Answer:

38 chromosomes are in the red foxes DIPLOID skin cells

Explanation:

There are two principal types of cells in the organism:

Gametes are the product of germ cell division by meiosis, and they have only one set of chromosomes, n (19 in this example). Their destiny is to merge in the process of fecundation, during which a new diploid cell called the zygote emerges through fertilization. The zygote is a complete diploid cell that suffers successive mitosis and forms a new organism (a new fox in this case).

- So, through meiosis, the diploid germ cell (2n) produces four haploid cells (n) that are the gametes.

- Through fecundation or fertilization, two gametes (n) merge and produce a diploid cell (2n) that is the zygote.

If the red fox gamete has 19 chromosomes (haploid number n, the single set of chromosomes), it must merge with another gamete (coming from the other parent) with 19 chromosomes to form the zygote. The zygote is a diploid cell. The zygote will suffer many mitosis divisions to become a new fox.

To know the number of chromosomes in a skin cell, we need to duplicate the number of chromosomes in the gamete (19).

Answer:

Carbon dioxide (CO2) makes up the vast majority of greenhouse gas emissions from the sector, but smaller amounts of methane (CH4) and nitrous oxide (N2O) are also emitted. These gases are released during the combustion of fossil fuels, such as coal, oil, and natural gas, to produce electricity.

Explanation:

What can Carbon do?

Carbon emissions affect the planet significantly, as they are the greenhouse gas with the highest levels of emissions in the atmosphere. This, of course, causes global warming and ultimately, climate change. Carbon dioxide is released into the atmosphere when fossil fuels — coal, natural gas, and oil — are burned.

Explanation:

Answer:

20%

Explanation:

Pairing do occur between a purine and a pyrimidine base or a pyrimidine and a purine base where Adenine pairs with Thymine and Guanine pairs with Cytosine.

DNA(deoxyribonucliec acid) sample is usually compose of 100% nucleotide base,

Since 30% of the sample section is compose of thymine then Adenine the base pair will also be 30% this is because adenine will always pair with thymine and each will occur in equal quantity. Together, adenine and thymine compose 60% of the segment.

While the remaining 40% of the section is composed of guanine and cytosine pairs and since the two bases will be equal in quantity, 20% of the DNA section will be cytosine nucleotide.

Answer:

A homo-zygous dominant genotype and a heterozygous genotype

Explanation:

A homo-zygous dominant genotype refers to a genotype that contains two copies of the dominant gene variant, i.e., two dominant alleles at its locus, thereby individuals carrying this genotype will show a dominant phenotype. Moreover, a heterozygous genotype is a genotype that contains both dominant and recessive alleles at its locus. In a heterozygous genotype, the dominant allele is always expressed and masks the recessive allele, thereby showing a dominant phenotype.

Answer:

The DNA of the cell tells the cell how to make proteins

Explanation:

Explanation:

Use the particle model of matter to explain why solids have a fixed shape, but gases fill the shape of the container they are in. ... The particles in a gas have very large spaces between them, so the particles can be 'squashed' closer together, meaning the gas can easily be compressed to take up a smaller volume.

Answer 1.- Well a duck is still a bird. So it has hollow bones that makes its body lighter.It eats insects, worms amphibians and plants, so it's an omnivore.2. It has hollow bones, it has an oily coating that prevents any water from settling in its duck feathers. 3. Feature no. 1-Makes body lighter so it's easier to swim, Feature 2- oily coating prevents water from getting into the feathers, preventing any water being absorbed into their bodies.

Explanation:

Answer:

1. Increase/occurrence

2. Heat

3. Warm

4. Global warming

Explanation:

Greenhouse effect is the process whereby heat is trapped by certain gases in the atmosphere called GREENHOUSE GASES e.g. carbon dioxide (CO2). Greenhouse gases have the ability to trap heat, hence, their increase in the atmosphere becomes a major concern as it starts becoming a bad occurrence.

An increase in the greenhouse gases in the atmosphere means more heat will be trapped, thereby, inducing the Earth to become WARM. This process where the Earth's temperature rises as a result of greenhouse effect is called GLOBAL WARMING.

Explanation:

In order to remove oxygen from the water, they rely on special organs called "gills." Gills are feathery organs full of blood vessels. A fish breathes by taking water into its mouth and forcing it out through the gill passages.

Answer: this is adaptation, but not in the way suggested in the question.

Explanation:

The question is suggesting that the 1% or so of turtle hatchlings that make it to maturity are the result of a variation that gives a selective advantage. This is not so. The only thing being selected for is sheer luck. The underlying adaptation is that all eggs hatch within a short period, so that predators are overwhelmed by numbers and some offspring by chance make it to the water, still dangerous, but less so than the sand. After the hatchlings reach the sea chance will still be a factor, but it is at this stage that natural selection may operate on advantageous variations.

There are two reproductive strategies, common to plants as well as animals. Turtles represent one of those strategies, which is to invest resources to produce large numbers of immediately self-sufficient offspring so that at least some will survive. The other strategy is to produce one or few offspring and invest resources in protecting and feeding it or them until self-sufficient and capable of surviving to maturity.

These are adaptations which are selected for because they confer advantage for the species concerned. One or the other may be the better solution depending on the species. Mammals, for example, invest in the latter strategy.

Explanation:

Answer

75% chance

Explanation:

The dominant and recessive are the terms used to explain the phenotypic traits and genetic makeup of an organism. The cross between a heterozygous species will result in a 75% chance of the species expressing a dominant phenotype.

The correct answer is:

Option B. 75%

The heterozygous condition refers to the one dominant and one recessive allele, whereas purebred is the condition in which both alleles are either recessive or dominant.

The dominant alleles are always expressed in purebred and heterozygous conditions.

The recessive alleles are expressed in purebred conditions only.

In the given attachment, consider the cross between round shaped-seeds in heterozygous conditions.

Thus, the chance of progeny will have round-shaped seeds is 75%.

Answer: A

Explanation:

Heterozygous means it has both a recessive and a dominate allele so in this case it’d be shown as Rr. For a parent to appear pink, the genotype must be rr (because r is recessive and won’t show up in the parent if there’s a dominant allele to over lower it). The only option that shows an Rr and rr pairing is option A
