Create a Punnett square to calculate the possible genotypes that can result from a cross between the two parent plants. In a dihybrid cross, the alleles of the gametes of each parent are written along the left side and top of the Punnett square, just as they are for a monohybrid cross. Fill in the squares with the predicted genotypes.
Answers
Answer:
In a dihybrid cross, the alleles of the gametes of each plant parent (PpRr x PpRr) are written along the left side and top to the Punnett square drawing. We can calculate the outcome of the genetic cross of (PpRr x PpRr). Since each parent has four different combinations of alleles in the gametes, there are sixteen possible. There will be nine (9) individuals with both dominant traits, three (3) individuals dominant for one trait, three (3) individuals dominant for the other trait and only one individual recessive for both traits.
In this case, we are looking at a subcategory of the plants dominant for both traits. Four of these nine will be heterozygous for both traits. The ratios can be represented as: 9:3:3:1.
For further information, please see the image attached.
Final answer:
To create a Punnett square for a dihybrid cross between the two parent plants, list the alleles from each parent's gametes along the left side and top of the square. The possible genotypes that can result from the cross are: PR, Pr, pR, and pr.
Explanation:
To create a Punnett square for a dihybrid cross between the two parent plants, the alleles from each parent's gametes are written along the left side and top of the square. In this case, both parents have the same gametes, so the Punnett square will be symmetrical. The possible genotypes that can result from the cross are: PR, Pr, pR, and pr. These genotypes represent the different combinations of alleles from the two parents.

Captive Breeding:
Captive breeding is an ex-situ conservation technique (taking the animal out of its natural habitat to increase population numbers in zoos or sanctuaries). Captive breeding involves selective breeding of endangered species to help produce a sizable population that can later be introduced back into the wild when their habitat improves.
Captive breeding programs include zoos, sanctuaries located away from the animal's original habitat. For example, the Toronto Zoo has operated a captive breeding program for the Blanding's turtle since 2012. The turtles are kept their for 2 years after birth and then released back into the wild.

Lakes can be formed as a result of what type of weathering? Select ALL that apply.
Glacier movement over the crust
Upwelling from the water table
Formation of a terminal moraine
Trapped acidic water dissolving large amounts of limestone
Answers
Answer:
Options A and D are correct:
Glacier movement over the crustTrapped acidic water dissolving large amounts of limestoneExplanation:
Glacial lakes: It has been well reported that glacial erosion often leads to the development of lakes. When a glacier moves, it erodes the sediments which lead to the formation of depressions. In later years, these depressions are filled with water and form a lake. This is why these lakes are recognized as "glacial lakes".
Lakes formed by dissolving limestone: We know that acids can dissolve the limestone (CaCO3) very quickly. Therefore, if acidic water traps in an area where the bed-rock is made up of limestone, the water will dissolve it and form a depression. The acidic water could stay the same place forming acidic lakes or could be replaced with normal water later on due to hydrogeological processes.

Which of the following is the MOST accurate regarding the speed of light?
A) The speed of light depends on the color of light that we see.
B) The speed of light is constant in all media at all times and places.
C) The speed of light can change as it moves through different materials.
D) The speed of light is only affected by the brightness of the light.
Answers
Answer:
C
Explanation:
The speed of light can change as it moves through different materials
Option C is correct; the speed of light can change as it moves through different materials, even though it remains constant in a vacuum and is not affected by the light's color.
The most accurate statement regarding the speed of light is that it can change as it moves through different materials, making option C the correct answer. The speed of light in a vacuum, denoted as c, is a constant value of approximately 3 × 10⁸ m/s, and is one of the fundamental constants of physics. This means that regardless of the motion of the source or the observer, the speed of light in a vacuum remains the same. However, when light passes through different materials, such as air, water, or glass, its speed is affected by the refractive index of the material. For instance, light travels slower in glass than in air. While the speed is constant in a vacuum and does not depend on the frequency or wavelength of light (thus, not on the color), it does vary in materials with different refractive indices.

cyanide is a poison that prevents mitochondria from using oxygen. as a result, the mitochondria cannot produce what?
Answers
Answer:
the mitochondria would not be able to produce energy
Explanation:
"the mitochondria is the powerhouse of the cell"
Final answer:
Cyanide poisoning inhibits the enzyme cytochrome c oxidase in the electron transport chain, preventing ATP synthesis and increasing the pH of the intermembrane space due to reduced proton pumping.
Explanation:
Cyanide is a poison that has a high affinity for the enzyme cytochrome c oxidase, which is an essential component of the electron transport chain in mitochondria. The enzyme's inhibition by cyanide prevents the transport of electrons from cytochrome c to oxygen, disrupting the electron transport chain and halting ATP synthesis.
As a result of cyanide poisoning, the electron transport chain cannot create an electrochemical gradient across the mitochondrial membrane, which is necessary for ATP production through oxidative phosphorylation. Thus, ATP synthesis stops, which can lead to cellular energy deficit and ultimately cell death.
Furthermore, due to the disruption of the electron transport chain, the pH of the intermembrane space would increase as proton pumping by the chain's complexes is halted. This decrease in the proton gradient further prevents ATP synthesis.

It was passed to the individual by a somatic cell from the father.
It was passed to the individual by a gamete from the father.
Half of the individual's cells descend from the father's gamete.
Half of the individual's nuclei descend from the nucleus of the father's gamete.
Answers
Answer:
B. It was passed to the individual by a gamete from the father.
Explanation:
DNA is transferred to the next generation via gametes, which are produced during meiosis. During meiosis, half of the genetic material is transferred from parent cell to their gametes. Therefore, among the given options, only B is correct.
Option A is not correct because it talks about somatic cells; whereas, in somatic cells, genetic material is not transferred half rather duplicate first and then a complete duplicated set of genetic material is transferred.
Option C is also not correct because only one gamete (sperm) fertilizes the egg. Hence, not half of his cells descend from father gamete. Similarly, option D is also incorrect because it is not possible to descend half of the nuclei from the father to the offspring.

polysaccharides, such as starch, have in common?
A They are lipids made of fatty acids.
B They are proteins made of amino acids.
C They are nucleic acids made of nucleotides.
D They are carbohydrates made of simple sugars.
Answers
Explanation:
D They are carbohydrates made of simple sugars.
Both disaccharides and polysaccharides belong to the category of carbohydrates, as they are both made up of simple sugars or monosaccharides. Two monosaccharides combine to form a disaccharide, while many monosaccharides join together to make a polysaccharide. Hence, both sucrose (a disaccharide) and starch (a polysaccharide) consist of simple sugars.
Explanation:Disaccharides like sucrose and polysaccharides like starch are both classified as carbohydrates. These compounds are constructed from smaller, simpler units known as simple sugars, or monosaccharides. Disaccharides are formed when two monosaccharides combine together, whereas polysaccharides are made of a larger number of monosaccharides. Hence the correct answer to your question is D - They are carbohydrates made of simple sugars.
Examples of monosaccharides include glucose and fructose, and these can combine in different ways to form disaccharides and polysaccharides. Sucrose, for example, is made of one glucose and one fructose molecule. Starch, on the other hand, is a polysaccharide made primarily of glucose units.

Answers
Photosynthesis and cellular respiration interconnect plants and human beings.
Explanation:
Plants prepare their own food and are autotrophs. Humans depend on autotrophs both directly and indirectly for food and are heterotrophs.
Heterotrophs consume both plants and animals to get energy
Photosynthesis: reactants - sunlight, carbon dioxide and water; products – sugar, oxygen
Cellular respiration: reactants - glucose and oxygen; products – water, carbon dioxide
Carbon dioxide (end product) released due to cellular respiration by the humans enters the atmosphere and is absorbed by the plants which become a reactant in photosynthesis.
Oxygen (end product) released due to photosynthesis by plants enters the atmosphere and is inhaled by human beings and becomes a reactant in cellular respiration.

A student claims that if the animal producing the spermatozoa has a mutation in a mitochondrial gene, the probability that any offspring will inherit the mutation is zero. Provide evidence to support claim.
Answers
Answer:
Mitochondrial DNA is inherited from the maternal side
Explanation:
Mitochondrial DNA is inherited from the maternal side (from the oocyte). The mitochondria from the sperm cell including their DNA are degrade after fertilisation.
The size of the cells that make the zygote also contribute to this. The oocyte is much larger than the sperm, containing around 100,000 mitochondria, whereas the much smaller sperm cell only contains around 100. This means even initially, there are very few paternal mitochondria compared to maternal mitochondria in the first place, effectively diluting them out.
This, coupled with the degradation of the sperm mitochondria, means that offspring will not inherit mitochondrial DNA and any mutations from their father.
Sperm or the spermatozoa is a male reproductive cell. It consists of flagella, head and body. The sperm or the male cell fertilizes with the female reproductive cell called the egg to produce offspring.
If the organism producing the spermatozoa has a modification in a mitochondrial gene, then the possibility of offspring having a mutation will be zero.
The explanation for the above statement is:
Mitochondrial gene is obtained from the maternal side that is the mother's reproductive cells (oocyte).The mitochondria of the male reproductive cell the sperm degenerate after the process of fertilization and do not take part further in the process.The abundance of female mitochondria outnumbers the mitochondria present in the sperm cells.Therefore, mitochondrial DNA transfers exclusively from the mother to the offspring.

Where do marine scientists get the ethical standards for their profession and what kind of values do they include?
Answers
Answer:
Explanation:
The ethical standard was accepted by the Society in the 2013 mid-year ballot. This Code states 17 guiding principles aimed at assisting the Society.
Some of the ethical issues include the potential for data fabrication/ falsification,
conflicts of interest, human subjects violations, working with scientific uncertainty and values conflicts in marine conservation.
Final answer:
Marine scientists acquire their ethical standards from scientific ethics, philosophical discussions, religious and environmental ethics, and community norms. These standards emphasize the minimization of harm to organisms and ecosystems, as well as unbiased research. Ethical reasoning features in education and policy to guide practitioners in morally complex situations.
Explanation:
Origins of Ethical Standards in Marine Science
Marine scientists derive their ethical standards from a variety of sources including scientific ethics, philosophical discourse, and environmental considerations. These standards aim to protect humans, animals, and ecosystems from undue harm while promoting research that is free from bias. Principles of ethics such as compassion, humility, respect, coexistence, and sustainability guide interactions with marine life, with an increasing focus on moral considerations as we learn more about marine cognition and consciousness.
Ethical dilemmas, intrinsic and extrinsic values, and the application of ethical reasoning are core components within the marine science field. This includes the management of fisheries and the conservation of rare and endangered species, where ethical assumptions can significantly influence policy and practice. Additionally, religious and environmental ethics contribute to shaping the values and norms that marine scientists may hold, especially when pondering grand questions about humanity's relationship with the ocean and its inhabitants.
To foster ethical conduct, the incorporation of ethical reasoning is advocated in curricula, major meetings, and agency operations. Emotion plays a critical role in shaping moral judgments, which is why the engagement of both hearts and minds is encouraged in ethical deliberations. This holistic approach helps marine scientists navigate complex ethical landscapes in their work.

5. Metaphase II
6. Telophase I
7. Prophase II
8. Telophase II
Explanation:
The phases of meiosis can be remembered using the acronym PMAT
The first stage (during Meiosis I), is called Prophase I. During this phase, the chromosomes condense and become visible and the nuclear envelope breaks down. Homlogous chromosomes pair up and crossing over occurs, meaning they exchange bits of DNA.
Next, Metaphase I occurs, in which the pairs of chromosomes move to the centre (equator) of the cell and line up long the equator.
Anaphase I then occurs, where special microtubules called spindle fibres pull the homologous chromosomes to opposite sides of the cell.
The next step is called Telophase I, in which the chromosomes gather at the poles, spindle fibres degrade, the cytoplasm divides and a new nuclear membrane forms - producing 2 daughter cells.
The cell now enters Meiosis II, the first stage of which is Prophase II. During prophase II, the chromosomes condense, the nuclear envelope breaks down again and a new spindle apparatus forms.
The next stage is Metaphase II, during which the chromosomes (now not in their homologous pairs as these have already been divided) are aligned in the centre of the cell, the equator.
The next stage is Anaphase II, in which the chromatids are pulled to opposite ends of the two daughter cells by the spindle.
The final stage is Telophase II, where 4 haploid daughter cells are formed after the reformation of the nuclear membranes, division of the cytoplasm and the chromatids uncoil.
