(A) As a result of metabolic inactivity, newly harvested fruits are unable to absorb ethylene gas from the atmosphere.(B) Ethylene gas is a chemical signal through which ripening fruits trigger the ripening process in other fruits.(C) Because of normal phenotypic variation, only some of the fruits in a given generation are expected to produce ethylene gas.(D) The rate of ethylene gas production by ripening fruits is an indicator of the relative age of an ecosystem.

Answers

Answer 1

Answer:

Option (B) Ethylene gas is a chemical signal through which ripening fruits trigger the ripening process in other fruits.

Explanation:

The ethylene hormone triggers the ripening process of fruit. However, in order to slow down the ripening process the action of ethylene is to be blocked. All fruits are capable to produce ethylene up to a certain level after which they start ripening. There are some classes of fruits that respond to the external ethylene such as apple, mango, tomato etc.  

Hence, option B is correct

Answer 2

The following describes the most likely connection between natural ethylene production and fruit ripening - (B) Ethylene gas is a chemical signal through which ripening fruits trigger the ripening process in other fruits.

Ethylene

A plant hormone or regulatory hormone found in form of a gaseous compound

Ethylene is a chemical signal through which ripening fruits trigger the ripening process in fruitsethylene signaling have shown a linear transduction pathway leading to the activation of ethylene response factors. Most fruits produce ethylene that starts the ripening process.Its level in under-ripe fruit is very low, but as the fruit develops, the production of ethylene becomes larger that speeds up the ripening process of fruit.

Thus, The following describes the most likely connection between natural ethylene production and fruit ripening - (B) Ethylene gas is a chemical signal through which ripening fruits trigger the ripening process in other fruits.

A sperm cell's acrosome ______.

A) contains the sperm's mitochondria
B) fuses with the plasma membrane of the egg cell
C) contains enzymes that are released when the sperm encounters an egg and dissolves a hole in the jellylike matrix that surrounds the egg
D) contains the sperm's nucleus and is the part of the sperm that enters the egg during fertilization

Answers

Answer:

C

Explanation:

Sperm cells do a great and tasking job in their quest for egg fertilization. First, they have to find an egg to fertilize by swimming a long distance, as not all released sperm finds an egg. The few that finds an egg still have to cross the egg's protective coat and fuse their own membrane with the plasma membrane of the the egg. This process of crossing the egg's barrier is referred to as ACROSOME reaction.

The acrosome is a lysosome-like vesicle located in between the sperm's plasma membrane and nuclear membrane (nucleus) derived from the golgi complex of the spermatid. It is closer to the plasma membrane at the tip of the sperm's head. The vesicle contains soluble proteolytic enzymes such as acrosin and inner membrane proteins such as bindin.

The acrosome reaction is the exocytosis of the acrosome, or the fusion of the acrosomal membrane with the sperm's plasma membrane. The process releases the acrosomal contents (lytic enzymes) to the outside of the sperm.

When the acrosome's proteolytic enzymes are released, they begin to degrade the egg's protein-rich protective coat. The egg's plasma membrane is surrounded by a thick ZONA PELLUCIDA layer made of extracellular matrix and a jelly-like cumulus layer surrounding it. This degradation creates a path for the sperm to swim through on its way to the egg's plasma membrane. This enables the plasma membranes of the egg and sperm to fuse placing both haploid nuclei (one from the sperm, the other from the egg) into the same cell, where they form the diploid genome of the new organism.

An advantage of gas exchange in fresh water, compared with gas exchange in air, is that:
a. water usually contains a higher concentration of oxygen than air
b. ventilation requires less energy in water
c. the respiratory surface does not have to be as extensive in water
d. water is easier to move over the respiratory surface
e. water loss through evaporation across the respiratory surface can be minimized

Answers

Answer:

e. water loss through evaporation across the respiratory surface can be minimized

Explanation:

Exchange of gases, otherwise known as respiration is an important process in living organisms during which food material within the body is broken down to unlock their energies for the functioning of living organisms.

During gaseous exchange, oxygen gas diffuses into respiratory tissues and dissolves on respiratory surfaces while carbon dioxide diffuses in the other direction.

Respiratory surfaces are usually thin walled with moist inner surfaces that enables the dissolution of gases. Depending on the atmospheric temperature, respiratory surfaces in terrestrial organisms are at varying risks of losing moisture to the atmosphere due to evaporation.

In aquatic organisms however, evaporation from respiratory surfaces is minimized as the immediate environment is water.

Options a to d are not entirely true about water and respiration.

The correct option is e.

Final answer:

The major advantage of gas exchange in fresh water, compared to air, is that water loss through evaporation across the respiratory surface can be minimized. This is crucial for water-dwelling organisms' survival.

Explanation:

The advantage of gas exchange in fresh water, compared to gas exchange in air lies within option e). Water loss through evaporation across the respiratory surface can be minimized in water. Freshwater species often have additional adaptations to prevent excessive water loss. For instance, fish have gills which allows for effective gas exchange whilst maintaining water balance. Gas exchange surfaces in water-dwelling organisms are usually kept moist to facilitate this exchange. Consequently, these organisms minimize water loss through evaporation which is vital to their survival. Note that options a, b, c, and d are not correct because water does not usually have a higher concentration of oxygen than air, ventilation requires more energy in water, the respiratory surface needs to be more extensive in water, and water is not necessarily easier to move over the respiratory surface.

When gene duplication occurs to its ultimate extent by doubling all genes in a genome

Answers

The gene duplication occurs to its ultimate extent by doubling all genes in a genome during mitosis.  

Explanation:

Mitosis is a process by which an Eukaryotic organism divides its cells into two cell keeping all the genetic setup and the genetic configurations same. During mitosis, at first, during the G0 phase of mitosis, the cell prepares itself for mitosis, where it duplicates its DNA and some of the other proteins required during cell division.

During the mitosis these DNAs concentrate as different chromosomes and are separated and pulled apart into two different poles by spindle fibers and two new cells are eventually formed. Thus, during mitosis, cells produce ultimate gene duplication.

(2) hormones present in replacement organs prevent the synthesis of antibiotics
(3) transplanted organs produce their own antibiotics
(4) antigens present in these organs attack antibodies already present in the blood

Answers

Answer:

Option 1

Explanation:

The organ transplanted is a foreign element for the body and the medication prescribed after transplantation surgery prevents this organ from the attack of immune system of the body.

Since the immune system is in habit of attacking all foreign agents, it poses highest risk in transplantation surgery and hence effective medication can prevent the organ form being rejected.

What body systems remove toxins from the body? What are "toxins," and where do they come from? Are all "toxins" alike? Do toxins really cause you to gain body fat or prevent you from losing weight?

Answers

Answer:

Basically, detoxification means cleansing the blood. This is done by removing impurities from the blood in the liver, where toxins are processed for elimination. The body also eliminates toxins through the kidneys, intestines, lungs, lymphatic system, and skin.

Toxins created by the body and even your emotions. These toxins come from industry, car exhausts, air and water pollution, pesticides, herbicides and radiation. They also are found in your hair care products, soaps, make-up, perfumes and cleaning products.

Obesity is a continually growing trend in countries that follow more Western diets and lifestyles, but what if this spike in weight gain can’t be entirely blamed on sugary or fatty foods and a lack of exercise? Turns out toxins contribute to fat storage and make it more difficult to lose those extra pounds too.

Hope it helps!!!!!!!!!!

Brainiest?

Final answer:

The excretory system and the liver play key roles in removing toxins, which are diverse substances from various sources that can affect health. The direct relationship between toxins and weight gain is not well-established, but a healthy excretory function supports overall health and can influence weight management.

Explanation:

The body systems responsible for removing toxins from the body are primarily the excretory system and the liver, which is part of the digestive system. Toxins can be substances such as pollutants, chemicals, and metabolic by-products that need to be cleared out to maintain health. They come from various sources like the environment, food, and the breakdown of bodily tissues. Not all toxins are alike, as they can be both external substances and internal waste products.

Beliefs that toxins are directly causing fat gain or preventing weight loss are not strongly supported by scientific evidence. While an accumulation of certain toxins in the body could potentially lead to negative health outcomes, how much they contribute to body fat gain is not well-established. However, a healthy functioning liver and excretory system are crucial for overall health and can indirectly support weight management by maintaining proper metabolism and bodily functions.

In general, the percentage of body weight that comes from bones, muscles, organs, or body fat varies from person to person, and factors such as diet, exercise, and individual metabolism can influence body composition. Health outcomes can indeed differ based on where body fat is stored, with abdominal (visceral) fat being linked to higher health risks than subcutaneous fat located in other body areas.

The codon AUG specifies the amino acid methionine. What would the tRNA anitcodon be that recognizes this codon?

Answers

Answer:

UAC

Explanation:

This example portrays that translation, which is the second process of protein synthesis, is about to occur. Translation cannot occur without a special type of RNA called tRNA or transfer RNA.

A tRNA contains a set of three nucleotides called ANTICODON. The tRNA matches an mRNA codon with the amino acid it encodes. The tRNA initially binds to the mRNA and reads the mRNA codon using its anticodon (which is complementary to the mRNA's codon). The actual reading is done by matching the base pairs through hydrogen bonding following the base pairing rule i.e. A-U, G-C. After reading the mRNA codon using its anticodon, it then carries the specific amino acid encoded by that codon it binds to, in order to add to the growing polypeptide chain.

For example, a codon AUG (start codon that signals beginning of translation) will be read by tRNA anticodon, UAC. Since the codon AUG codes for amino acid, Methionine. The tRNA then carries Methionine via its amino acid attachment site and adds to the polypeptide chain (future protein).

A new kind of tulip is produced that develops only purple or pink flowers. Assume that flower color is controlled by a single-gene locus, and that the purple allele (C) is dominant to the pink allele (c).

a. Determine the frequency of the purple and pink alleles in this field population.
b. Estimate the proportion of all purple flowering plants that are heterozygotes and homozygotes.
a. purple allele (C) = 0.609, pink allele (c) = 0.391
b. purple homozygotes = 371, pink homozygotes = 153, heterozygotes = 476

Answers

Answer:

a. purple allele (C) = 0.609, pink allele (c) = 0.391

b. purple homozygotes = 371, pink homozygotes = 153, heterozygotes = 476

Explanation:

Given -

Purple flowers - 847

Pink flowers - 153

The frequency of recessive genotype i.e

[tex]q^ 2 = \frac{153}{1000} \\q^ 2 = 0.153\\[/tex]

Frequency of recessive allele i.e q is equal to

[tex]q = \sqrt{0.153} \\q = 0.391[/tex]

As per hardy Weinberg's first equilibrium equation -

[tex]p + q = 1\\p = 1-q\\p = 1-0.391\\p = 0.609[/tex]

Frequency of purple homozygous species

[tex]= p^2\\= 0.609^2\\= 0.371[/tex]

Number of purple homozygous species [tex]= 0.371 * 1000= 371[/tex]

Number of pink homozygous species [tex]= 0.153 * 1000= 153[/tex]

Heterozygous species is equal to

[tex](1-0.371-0.153)* 1000\\= 0.476 * 1000\\= 476[/tex]

Answer:

a. purple allele (C) = 0.609, pink allele (c) = 0.391

b. purple homozygotes = 371, purple heterozygotes = 476

Explanation:

According to Hardy-Weinberg equilibrium:

p + q = 1

p² + 2pq + q² = 1

where, p = frequency of dominant allele

q = frequency of recessive allele

p² = frequency of dominant homozygous genotype

2pq = frequency of heterozygous genotype

q² = frequency of homozygous recessive genotype

a. Assuming the population is in Hardy-Weinberg equilibrium,

frequency of pink flowers (cc) = q² = 153/1000 = 0.153

frequency of pink allele c = q = √0.153 = 0.391

p + q = 1 where p = frequency of dominant allele

So, frequency of purple allele C = p = 1-0.391 = 0.609

b. Purple homozygotes = CC = p² * total population =

(0.609)² * 1000 = 370.88 = 371

Purple heterozygotes = Cc = 2pq * total population =

2 * 0.609 * 0.391 * 1000 = 476.23 = 476

This prediction strongest supports the conclusion that the gibbon population will decrease by 10 percent every year until it reaches a minimum size, which it will then maintain (which corresponds to option B). This conclusion assumes that the gibbons' population size is directly correlated with the carrying capacity of the environment, which in this case is decreasing due to deforestation.

However, when he attempts poses, he is unable to manipulate his body into each pose, and has difficulty holding some poses. According to SCT, why does Ron have difficulty holding these poses? What is the percent composition by mass of nitrogen in the compound N2H4 (gram-formula mass = 32 g/mol)? In pea plants, the allele for purple flower color is dominant to the allele for white flower color. If you were to perform a test cross to determine the genotype of a purple-flowered plant, what would you expect the phenotypic ratio of purple-flowered to white-flowered progeny to be if the plant is homozygous? And what would you expect if the plant is heterozygous?A. If the purple-flowered plant is homozygous, then the progeny would all have purple flowers; if the purple-flowered plant is heterozygous, then the progeny would have purple to white flowers in a 1:1 ratio.B. If the purple-flowered plant is homozygous, than the progeny would all have white flowers; if the purple-flowered plant is heterozygous, then the progeny would have purple to white flowers in a 1:1 ratio.C. If the purple-flowered plant is homozygous, than the progeny would have purple to white flowers in a 1:3 ratio; if the purple-flowered plant is heterozygous, then the progeny would have purple to white flowers in a 1:1 ratio.D. If the purple-flowered plant is homozygous, than the progeny would all have purple flowers; if the purple-flowered plant is heterozygous, then the progeny would have purple to white flowers in a 3:1 ratio.E. If the purple-flowered plant is homozygous, than the progeny would have purple to white flowers in a 1:3 ratio; if the purple-flowered plant is heterozygous, then the progeny would have purple to white flowers in a 1:3 ratio. 3.

The fundamental attribution error is also known as the: a) partner difference. b) self-serving bias. c) correspondence bias. d) matching bias. Polyvinyl chloride, or PVC, is used in most water-carrying pipes in the United States. Known for their resistance to the corrosion that can be caused by water, PVC pipes are more durable than the metal pipes of old. As useful as PVC is, it may be surprising that it was accidentally discovered in 1835 by Henri Victor Regnault, who observed a mysterious white solid plastic forming inside some test tubes that were left exposed to sunlight in his lab. It can be inferred from the passage that metal pipes:A. are used more than PVC pipes outside of the United States B. are more expensive than PVC pipes C. are more likely to corrode than PVC pipes D. are no longer used in the United States A sample of 41 observations is selected from one population with a population standard deviation of 3.4. The sample mean is 100.0. A sample of 45 observations is selected from a second population with a population standard deviation of 5.6. The sample mean is 98.4.
