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.

Use a Punnett square diagram to show why, for each pregnancy, the chances of giving birth to either a boy or a girl are 50-50. Explain the results shown in your diagram.
Answer:
Because the offspring of a male and female are always going to be xx, xx, xy, or xy.
Explanation:
Remember that men have different reproductive chromesomes than women. Women have 2 x chromesomes(xx) while men have 1 x and 1 y(xy). These are given down to their offspring.
So we can write the this out in a punnet square as(link down below).
After you see the visual, you will find that the genotypes are xx, xx, xy, xy.
As I said above, women have sex chromesomes xx, while men have sex chromesomes xy. When you match the genotypes on the punnet square with the ones we know from men and women, we find that two of them match with men and two match with female.
So with this, we can conclude that 2/4 of offspring will always be male and 2 will be female. And as you well know 2/4 is 1/2 which is 50%.

Which is NOT a benefit of xenophyophores in a habitat?
1 They maintain benthic biodiversity.
2 They increase populations of isopods, mollusks, and crustaceans.
3 They churn up sediments that build up on the ocean floor.
4 They convert salt and iron into energy and nutrients.
The correct answer is 4. They convert salt and iron into energy and nutrients.
Explanation
Xenophiophores are large single-celled organisms generally found deep in the deep sea. They are characterized by being very delicate organisms, which makes it difficult for scientists who intend to study them since they are easily damaged by manipulation. However, in the studies that have been carried out on these organisms, it has been found that they are irreplaceable agents in the sediment deposition process and the maintenance of the biological diversity of benthic organisms. Also, it has been shown that in the areas where these organisms are found there are three to four times more benthic crustaceans, echinoderms, and mollusks than the equivalent areas not inhabited by these organisms. On the other hand, none of these studies has proven that They convert salt and iron into energy and nutrients. Therefore, the correct answer is 4. They convert salt and iron into energy and nutrients.

Why is stem cell research important within the field of medicine?
15. Suppose a human blood cell containing a 0.9 percent solute concentration were put into a container of 30 percent solute solution. Would the blood cell get bigger or smaller? Why? In your explanation, you must tell me which area has the hypotonic solution (inside the blood cell or outside the blood cell), which area has the hypertonic solution (inside the blood cell or outside the blood cell), and which direction the water would be moving (into the cell or out of the cell).
Answer:
Smaller
Explanation:
The human blood cell has a smaller percentage of solute concentration than the solution it was placed into. This means that the cell is hypotonic in comparison to the solution, and the solution is hypertonic compared to the cell. When a cell is placed in a hypertonic solution it undergoes crenation, meaning it shrivels up. Water moves from the lower solute concentration to the higher solute concentration. The water inside the cell moves outside to the hypertonic solution. This causes the cell to become smaller.

Explain the importance of using engine powered pump for irrigation works.
Answer and Explanation:
Engine irrigation pumps are used to propel water into the irrigation channels, providing full water supply to agricultural crops. The use of the engine pump has advantages and disadvantages. Among the advantages, we can present the simplicity of operation of these pumps, being easily operated efficiently. They also save energy and are essential for irrigation with more viscous liquids, when necessary. This feature is the main reason for using this type of pump.
Among the disadvantages we can say that these pumps have a slower and less accurate work.

What are the two main ways bacteria cause illness?
A. By releasing toxins that poison your cells
B. By using your cells to make copies of themselves
C. By changing the genetic material inside your cells
D. By breaking down your cells for nutrients
Answer:
A. By releasing toxins that poison your cells
B. By using your cells to make copies of themselves
Explanation:
Within the body, bacteria can divide (multiply) and kill host cells by disrupting their normal functioning. Moreover, bacteria secrete toxins that are able to destroy host cells' metabolic machinery. For instance, many bacteria synthesize exoenzymes and interferons that disrupt and destroy host cells. Bacterial toxins can be synthesized internally in order to develop sensitivity through antigenic properties.

In the liver, excess amino acids are broken down into ____________ and rapidly combine with ____________ to produce urea, which is much less toxic to cells.
Answer:
In the liver, excess amino acids are broken down into ammonia and rapidly combine with carbon dioxide to produce urea, which is much less toxic to cells.
Explanation:
The correct answer to the given quested about Urea Cycle is Ammonia and Carbon dioxide respectively and the complete statement will be "In the liver, excess amino acids are broken down into Ammonia and rapidly combine with Carbon Dioxide to produce urea, which is much less toxic to cells."
What do you mean by Urea Cycle?The urea cycle, commonly referred to as the ornithine cycle, is a series of metabolic processes that converts ammonia into urea (NH2)2CO (NH3).Highly poisonous ammonia is transformed into urea by rapidly combining with carbon dioxide via the urea cycle for elimination. Five years before the TCA cycle was found, this cycle was the first to be identified as a metabolic process. Later, Ratner and Cohen provided a more thorough explanation of this cycle.Thus we can conclude that in the liver, excess amino acids are broken down into Ammonia which is highly toxic to cells and that ammonia rapidly combine with Carbon Dioxide to produce urea, which is much less toxic to cells.

Which of the following factors decrease biodiversity? (Choose all that apply)
a. habitat destruction
b. unpredictable precipitation
c. warm temperatures
d. freezing temperatures
Answer:
habitat destruction, unpredictable precipitation, and freeing temperatures.
Explanation:
i took the quiz
The destruction of the habitat, unpredictable precipitation, and freezing temperatures decreases biodiversity. Thus, options a, b, and d are correct.
What is biodiversity?Biodiversity is the variety of life that sustains on earth and lives in a particular habitat. The biodiversity can be measured based on the ecosystem, species, and genetics. It comprises the ecological and evolutionary process.
The destruction of the habitat of a species can lead to a decrease in biodiversity as it affects the ecosystem and the ecological pyramid as a whole and will affect the population of the species.
The unpredictable precipitation can affect the species and the habitat as it may lead to floods that will destroy the habitat hence resulting in the loss of species.
Similarly, the decrease in temperature will affect many species as they will not be able to cope with low temperature resulting in their death.
Therefore, the unpredictable precipitation, freezing temperature, and destruction of habitat lead to a decrease in biodiversity.

write a paragraph that explains what the causes of Long term climate cycles are. Give examples
Explanation:
Scientists have predicted that long-term effects of climate change will include a decrease in sea ice and an increase in permafrost thawing, an increase in heat waves and heavy precipitation, and decreased water resources in semi-arid regions.
Below are some of the regional impacts of global change forecast by the Intergovernmental Panel on Climate Change:
North America: Decreasing snowpack in the western mountains; 5-20 percent increase in yields of rain-fed agriculture in some regions; increased frequency, intensity and duration of heat waves in cities that currently experience them.
Latin America: Gradual replacement of tropical forest by savannah in eastern Amazonia; risk of significant biodiversity loss through species extinction in many tropical areas; significant changes in water availability for human consumption, agriculture and energy generation.
Europe: Increased risk of inland flash floods; more frequent coastal flooding and increased erosion from storms and sea level rise; glacial retreat in mountainous areas; reduced snow cover and winter tourism; extensive species losses; reductions of crop productivity in southern Europe.
Africa: By 2020, between 75 and 250 million people are projected to be exposed to increased water stress; yields from rain-fed agriculture could be reduced by up to 50 percent in some regions by 2020; agricultural production, including access to food, may be severely compromised.
Asia: Freshwater availability projected to decrease in Central, South, East and Southeast Asia by the 2050s; coastal areas will be at risk due to increased flooding; death rate from disease associated with floods and droughts expected to rise in some regions
