Photosynthetic organisms take light energy and use it to make their own "food". In this process they use carbon dioxide and light to make sugars and oxygen. This is great for other animals that utilize this oxygen and eat the plants for food.

Photosynthesis benefits all living things because chloroplasts absorb sunlight. In photosynthesis, water (H2O) and carbon dioxide (CO2) both reacts to form glucose (C6H12O6) that is actually food for the plants. Therefore, all living organisms get benefits by eating a similar type of food that gives energy to them. All animals and even human gets much of minerals and vitamins from plants when it is consumed.

your answer would be a characteristic known as albedo temperature

Answer: A characteristic known as albedo temperature.

Animals do not need the sun. Animals need glucose or whatever quick energy they can live on

Plants and animals both rely on cellular respiration for energy, but only plants perform photosynthesis to create the glucose needed for cellular respiration. Animals must consume food to get the glucose they need.

Plants and animals both rely on cellular respiration to produce ATP, a form of chemical energy that cells can use. However, while animals take in food that they then break down to fuel cellular respiration, plants generate their own food through a process called photosynthesis.

In photosynthesis, plants convert sunlight, carbon dioxide, and water into glucose. This glucose can then be used in cellular respiration to produce ATP. In other words, photosynthesis enables plants to create the fuel they need for cellular respiration.

Animals, on the other hand, do not have the capability to do photosynthesis. They cannot convert sunlight into chemical energy, so they must rely on consuming food to get the glucose they need for cellular respiration.

Adult stem cells are rare. Their primary functions are to maintain the steady state functioning of a cell—called homeostasis—and, with limitations, to replace cells that die because of injury or disease

Answer:

Adult stem cells are that present throughout the body of an individual that divide to restore or fill the place of dying cells or the cells that are damaged are regenerated by these cells.

They are present in adults and as well as in the children known as somatic cells. The major role of these stem cells to maintain the continuity of the cell functioning and replace the dead or regenerate the damaged cell by injury or the disease.

Thus, the correct answer is - replace or regenerate the dead or injured cells respectively.

"When autoinducers produced by one bacterium cross the membrane of another, they bind to receptors in the cytoplasm. This autoinducer/receptor complex is then able to bind to DNA promoters and activate the transcription of quorum sensing-controlled genes. In this way, individual bacteria within a group are able to benefit from the activity of the entire group."

Answer:

The concentration of chemical auto inducers increases with increase in population density

Explanation:

There is something known as Quorum sensing which is a sort of cellular communication in bacteria established through chemical signals. A bacterium is enabled to observe/monitor the environment and thus produce a widespread change in the species with in a community. These sensing processes are effective only when large numbers of cells are doing sensing controlled process together. A bacteria releases auto-inducers whose concentration increases when the population density of cells increase.

Answer:

The correct option is A. The oxygen atoms diffuse through the atmosphere and are inhaled by animals.

Explanation:

Photosynthesis can be described as a process in which plants use the light from sun to convert carbon dioxide and water into glucose. Oxygen is made as a by-product of this reaction. This oxygen is released into the atmosphere by the plants through the mechanism of diffusion.

The oxygen released into the atmosphere is taken up by animals. Animals utilize this oxygen for the process of respiration.

The process of respiration and photosynthesis are opposite to each other.

The oxygen released during photosynthesis is given off into the atmosphere and is available for respiration by many organisms, including humans. It plays a vital role in maintaining the balance of gases in the earth's atmosphere and is essential to the oxygen-carbon dioxide cycle.

During the process of photosynthesis, plants use sunlight, water, and carbon dioxide to produce glucose and oxygen. The oxygen produced as a byproduct is released into the atmosphere, which makes it available for organisms, including humans, to breathe.

Oxygen released during photosynthesis plays a vital role in supporting life on earth. Not only does it provide a critical element needed for respiration, it also helps to maintain the balance of gases in the earth's atmosphere.

For example, when humans and animals inhale, they take in oxygen and exhale carbon dioxide. The carbon dioxide is then used by plants during photosynthesis, effectively completing the oxygen-carbon dioxide cycle.

Explanation:

The seven characteristics of life are order, sensitivity or response to the environment, reproduction, growth and development, regulation/homeostasis, energy processing, and evolution.

Order refers to the organization of living things, such as the arrangement of cells or body parts. Sensitivity allows organisms to respond to stimuli in their environment. Reproduction is the ability to produce offspring.

Growth and development involve an increase in size and change over time. Regulation and homeostasis refer to the ability to maintain a stable internal environment. Energy processing involves the use of energy to carry out life processes. Evolution is the change in inherited characteristics over successive generations.

It's C Fungi cannot make their own food

The right option is; C)

Fungi cannot make their own food is the statement that BEST describes why mycelium, constructed of hyphae, are necessary for fungi survival.

Mycelium are the vegetative part of any fungus, consisting of a mass of branching, threadlike hyphae, usually found under the ground or inside the substrate on which the fungi are growing. The large masses of hyphae within the mycelium perform an essential role by obtaining nutrients from the organic substrates in which the fungi live or from beneath the soil to support fungi growth and its survival. This is because fungi do not have chlorophyll and cannot manufacture their own food.

Some frogs are slimy because they are covered in a mucous coating. This coating helps them keep their skin moist which helps them breathe through their skin. The mucous often contains other chemicals, like antibacterial or anti fungals to help protect the frog.

I hope this helps you

Amphibians are slimy due to their permeable skin and mucus glands, which help in respiration, moisture retention, and protection against predators. This slimy layer is essential for amphibians' survival in their wet habitats and plays a crucial role in their sensitivity to environmental changes. The mucus can also contain toxins to deter threats.

Amphibians, such as frogs, toads, salamanders, and newts, are known for their slimy appearance, which is a result of their unique skin properties. Their skin is permeable and contains mucus glands that secrete a moist layer of mucus. This moist layer is crucial for their survival as it helps in cutaneous respiration, allowing them to absorb oxygen and release carbon dioxide directly through their skin. Additionally, the mucus serves to keep their skin moist, protecting them from dehydration while also facilitating easier movement in water.

Another vital role of the mucus is to protect amphibians from predators. In some species, the mucus contains toxins which can deter or harm potential threats. The unique skin of amphibians also means they are especially sensitive to environmental changes and pollution, making them important indicators of ecosystem health.

Living both on land and in water, amphibians have adapted to their environments with features like a lightweight skull and calcified bones to support movement and respiration in both mediums. Their skin's capacity to absorb water and gases directly is why amphibians are often found in moist environments and why they are at risk in dry or polluted conditions.

Step 5

tRNA releases the amino acid at the top, which joins the chain of amino acids being produced

Answer:

The correct answer is: C) 2, 4, 1, 3, 5.

Explanation:

Translation is the name of the process in which proteins are synthesized. For it to be possible, translation requires 1 mRNA molecule, tRNA molecules, and 1 ribosome (that is also made of RNA).

First, the mRNA (messenger RNA) is synthesized in the nucleus by using a DNA sequence as a template. This is how DNA is involved in protein synthesis. Now, this mRNA molecule, binds to a ribosome - which is a structure made of two subunits composed of rRNA. The mRNA sequence is read by the small subunit of the ribosome, while the large subunit binds to the tRNA (transfer RNA). Each tRNA molecule is specific for one of the 20 possible amino acids. For each group of 3 nucleotides (codon) in the mRNA, there's an anticodon provided by the tRNA molecule - this is how the mRNA sequence is read and translated into a protein. Once assembled the ribosome, the mRNA and tRNA, the amino acids carried by the tRNA will bond with one another and form a polypeptide. This process repeats itself until a stop codon in the mRNA appears and signals the end of the translation. When translation ends, the protein is complete, so the ribosome releases both the mRNA and the polypeptide.

The frequency of the heterozygous rabbits is 0.65. The frequency of the B allele is 0.675. The frequency of the b allele is 0.325.

a. The frequency of heterozygous rabbits can be calculated by subtracting the frequency of the homozygous dominant genotype (BB) from 1. Since the frequency of the BB genotype is 0.35, the frequency of heterozygous rabbits is 1 - 0.35 = 0.65.

b. The frequency of the B allele can be calculated by adding half of the frequency of the heterozygous genotype (Bb) to the frequency of the homozygous dominant genotype (BB). Since the frequency of the BB genotype is 0.35 and the frequency of the Bb genotype is half of the frequency of heterozygous rabbits (0.65/2 = 0.325), the frequency of the B allele is 0.35 + 0.325 = 0.675.

c. The frequency of the b allele can be calculated by subtracting the frequency of the B allele from 1. Since the frequency of the B allele is 0.675, the frequency of the b allele is 1 - 0.675 = 0.325.

The Hardy-Weinberg equilibrium and its principals can be used to answer all the genetics-related questions about rabbits, lizards, humans and more. The frequency of genotypes can be calculated by dividing the population of each genotype by the total population size. To determine if populations are in Hardy-Weinberg equilibrium, we need to compare observed frequencies with predicted frequencies and see if they match.

In answering your questions, it is crucial to understand the Hardy-Weinberg equilibrium and its equation p^2 + 2pq + q^2 = 1.

For your first questions, without further information, it is impossible to accurately determine the frequency of heterozygous rabbits (Bb) or the frequencies of the alleles (B and b). However, you can generally calculate the frequency of the b allele from the frequency of bb rabbits and the B allele frequency from the overall allele total.

For the lizard question, the frequency of genotypes would be calculated by dividing the number of each genotype by the total population size. The Hardy-Weinberg equilibrium isn't necessarily maintained because drift and selection could have occurred in the population. We would need to analyze if the frequencies of the genotypes match the predicted frequencies based on the allele frequencies: p^2, 2pq, and q^2.

In relation to the human blood type question, the same calculation applies as for the lizard, by dividing the population of each genotype by the total population size. However, in predicting the new generation under the Hardy-Weinberg equilibrium, we would need to make some assumptions like infinitely large population size, random mating, no mutation, no migration, and no selection, which are not likely to be true in a real population.

For the birds, it seems that you might have gotten the dominance relationships reversed. In this case the frequency of each allele could be determined by finding the frequency of the recessive phenotype (assuming it is homozygous) then taking the square root (getting q), and p = 1 - q. However, the frequencies of the genotypes isn't straightforward because dominance doesn't tell you anything about the heterozygotes.

For your final question, if 9% of an African population is born with the severe form of sickle-cell anemia (ss), this means that q^2 = 0.09 and q = 0.3. Using this, p can be solved as 1 - q = 0.7, and 2pq gives the estimated proportion of heterozygous individuals in the population.
