if a human has an extra copy of one pair of homologous chromosomes, how many chromosomes will she have in total?

Answers

Answer 1
the DNA has replicated so there is a double copy of each of the 46 chromosomes (23 pairs of homologous chromosomes).

Answer:

How Do Cows Reproduce?

12 to 14 months is the age of puberty in a cow, but early maturing breeds do reach puberty by the time they are around 7 to 9 months of age. Cattle producers are working towards using science to bring that age down so that milk and meat producers can start using their cattle at a younger age. Usually, it's best to wait until they are at least 15 months of age before breeding cattle. This is so that their bodies have fully matured before trying to get them to reproduce. Even with the early maturing breeds you should wait around 13 to 15 months of age before you can breed them. The Estrous Cycle of Cattle averages a 21-day period. The length of ovulation varies partly depending on the species. The mean time of ovulation for dairy cows is 15 ± 2.6 hours. But the ovulation time does vary greatly, here are some other examples: Short- horn, 12.69 ± 1.15 hours; Angus, 13.93 ± 1.68 hours; and Hereford, 13.5 ±.87 hours. (www.sciencedirect.com/science/article/pii/S0022030241953912) A cow's gestation period (how long after insemination the mother is pregnant with the calf) is approximately nine months. But if your cow has calved before, there's a good chance she'll give birth after the same number of days as before. Some things you should consider when breeding cattle are as follows:

Safety- Your safety is more important than the animals, so it is smart to learn good safety measures when breeding such a large animal.

Fertility- You should get the IBR vaccine for your cows because IBR can cause the unborn calves to die. This situation is also known as an IBR abortion. Appropriate management of the bull is also an important factor when considering infertility. For example, you must have an appropriate bull to cow ratio for your farm and pastures.

Mating or insemination? - many farmers take the less natural rout of artificial insemination to grow there heard because they do not have to have a prized bull to have their cow breed with one. It can save farmers money to use artificial insemination, but it also flattens out the gene pool because lots of people are using the same animals so there’s less diversity. There are pro’s and con’s to both sides so make sure you do your research before deciding what method to take for breeding.

Breeding plan- Setting up a breeding program involves setting a breeding goal, making the selection of parents, and then carrying out the mating or artificial insemination. Your breeding plan should be specific to you and your farm.

E. Climate change is caused solely by the ozone hole because the hole lets in more radiation, whereas
ocean acidification is the consequence of accumulation of methane in the ocean sediments.

Answers

Answer:

Explanation:

A because Climate Change and Ocean Acidification Impacts on Marine Ecosystems. ... Acidification harms shell-forming plants and animals including surface and deep-water corals, many plankton, pteropods (marine snails), mollusks (clams, oysters), and lobsters.

While the term “ocean acidification” refers to the overall alteration in ocean chemistry caused by atmospheric carbon dioxide inputs, “coastal acidification” refers to a different mechanism by which coastal chemistry can change. Thus, option A is correct.

What ocean acidification different from climate change?

The average pH of the ocean is 8.1 right now, making it basic (or alkaline), but when more CO2 is absorbed, the pH decreases and the ocean becomes more acidic.

Because of human activity, atmospheric carbon dioxide concentrations are rising, which causes more carbon dioxide to evaporate and enter the ocean.

Due to its extensive effects, ocean acidification is consequently the global warming's evil twin. In actuality, the disruption of the natural carbon cycle, which is the cause of both processes, is the same issue.

Therefore, This describes how the atmosphere, land plants, and oceans constantly exchange carbon.

Genes A, B , C and D are present on the same chromosome. The recombination frequency between the genes is as follows: A and B: 24%, A and D: 16%, B and C: 18%, C and D: 10%. What is the correct order of genes along the chromosome

Answers

Answer:

BDCA

Explanation:

Recombination, also know as crossing-over, refers to the exchange of genetic material (DNA) between non-sister chromatids of homologous chromosomes during cell division (meiosis). The recombination frequency refers to the frequency of crossover between two genes/loci during meiosis. The recombination frequency is not a direct result of the physical distance between genes/loci on the same chromosome, but this value provides a good approximation of such distance. The recombination frequency is measured in centimorgans (cM), where 1 cM is equal to a 1% chance of recombination. The higher the recombination frequency between two genes/loci, the greater the chance that a cross-over will occur between them, and the greater the distance between them. Moreover, the lower the recombination frequency between two genes/loci, the lower the probability that they will separate by recombination, and the more closely they are linked.

The coniferous forests are the forests which have their vegetation composed primarily of the cone-bearing needle-leaved or scale-leaved evergreen trees, that are found in areas which have long winters and moderate to high annual precipitation.

Most of the animals which migrate to the warmer climates once the cold weather begins as they could not adapt to the conditions of coniferous forests. Some animals have adapted to life in the taiga by hibernating when the temperature drops. Other animals have adapted to the extreme cold temperatures through the production of a layer of insulating feathers or fur to protect them from the cold.

Why is protein synthesis important when we talk about genetic variation?

Answers

Answer:

Protein synthesis is the process all cells use to make proteins, which are responsible for all cell structure and function. In transcription, DNA is copied to mRNA, which is used as a template for the instructions to make protein. In the second step, translation, the mRNA is read by a ribosome. The key to a protein molecule is how the amino acids are linked. The sequence of amino acids in a protein is a type of code that specifies the protein and distinguishes one protein from another. A genetic code in the DNA determines this amino acid code.

Explanation:

. One function of the circulatory system is to help maintain a uniform body temperature. Explain how the constant circulation of blood through the body can accomplish this.

Answers

Answer:

Capillaries are the blood vessels with the smallest diameter and those closest to the surface of the skin. The blood that circulates through them is therefore closer to the outside air than the blood in the rest of our blood vessels. As the capillary dilates, a greater amount of blood is exposed to the air, which allows it to cool down and our body temperature to be maintained.

Explanation:

Blood is a solution where solutes and cells are found and that participates in homeostatic mechanisms such as the control of body temperature, helping to regulate respectively the preservation and elimination of heat. Blood vessels are the routes of the cardiovascular system, which are responsible for being a means of transport for blood with and without oxygen that reaches all tissues and returns to the heart. In very hot weather, surface thermoreceptors signal the brain that something needs to be done to dissipate heat. For this reason, a vasodilation process is activated, which allows blood to flow to the outermost layers of the skin. This promotes a heat exchange with the environment, which helps the individual to lower their body temperature. Cold causes a decrease in blood flow by reducing the size of the vessel (arteries or veins) through which blood and other substances circulate. By reducing the size of the vessel, the substances that circulate in the blood are also reduced. The heat causes an increase in the size of the blood vessels, which generates greater transport of nutrients through the blood.
