For keyboard navigation, use the up/down arrow keys to select an answer. a the relative distance between the genes b the presence of more than two alleles at each locus c that genetic material was being exchanged with the Y chromosome d the number of genes that could be found on any given chromosome
Answer:
The correct option is a) the relative distance between the genes.
Explanation:
A short distance between genes is a very little target for crossing-over to occur, which means that only a few of them will happen, compared with the number of events between genes that are more separated between each other.
Two genes that are very close have a few recombination events and are strongly bounded. These genes are linked.
The percentage of recombination frequency (P = Recombinant number / Total of individuals) is useful to determine the genetic distance between two or more genes. This distance results from multiplying that frequency by 100 and expressing it in map units (MU) or centiMorgans (cM). One centiMorgan (cM) equals one map unit (MU).
The map unit or centiMorgan is the distance between the pair of genes for which every 100 meiotic products only one results in a recombinant product.

What does the ATP molecule transfer to the sodium potassium pump?
Answer:
Using the energy from ATP, the sodium-potassium moves three sodium ions out of the cell and brings two potassium ions into the cell.
The pump binds ATP and three sodium ions to the cytoplasm where ATP then phosphorylates the pump and it changes shape, opening an opening to the outside of the cell and sodium is released and two potassium ions are taken up .
What is Sodium potassium pump?A sodium-potassium pump is defined as an enzyme found in the membrane of all animal cells where it performs many functions in cell physiology. The Na⁺/K⁺-ATPase enzyme is activated. For every ATP molecule used by the pump, three sodium ions are exported and two potassium ions are imported.
In this Na+ K+ pump which is an electrogenic transmembrane ATPase which was first discovered in 1957 and is located in the outer plasma membrane of cells; on the cytosolic side. The Na+ K+ ATPase pumps 3 Na+ out of the cell and 2 K+ into the cell for every ATP consumed.
Thus, the pump binds ATP and three sodium ions to the cytoplasm where ATP then phosphorylates the pump and it changes shape, opening an opening to the outside of the cell and sodium is released and two potassium ions are taken up.

Your friend is taking a Genetics lab at UT. She needs some help with a lab report so she calls you for some advice—she knows you will be able to help since you are taking Genetics. After analyzing data from a three point cross she has lost her lab manual. The only thing she can find is that the Interference in this cross was 0.68. She remembers a testcross was done with a heterozygous female and that the genes being analyzed were forked bristles, crossveinless wings, and white eyes. She also tells you that there is an equal distance between these genes. What is this distance if she counted 3 double crossover progeny out of 500 total progeny?
Answer:
The distance between these genes is 0.9375 MU
Explanation:
To calculate the coefficient of coincidence, CC, we must use the next formula:
CC= observed double recombinant frequency/expected double recombinant frequency
Note:
observed double recombinant frequency=total number of observed double recombinant individuals/total number of individuals expected double recombinant frequency: recombination frequency in region I x recombination frequency in region II.The coefficient of interference, I, is complementary with CC.
I = 1 - CC
Available data:
• Interference = 0.68
• Equal distance between genes
• 3 double crossover progeny
• Total number of individuals in the progeny, N = 500
We know that
CC= observed double recombinant frequency/expected double recombinant frequency
CC = (total number of observed double recombinant individuals/total number of individuals)/( recombination frequency in region I x recombination frequency in region II)
I = 1 - CC
So, all we need to do is to clear each formula with the data given in the problem:
I = 1 - CC
0.68 = 1 - CC
CC = 1 - 0.68
CC = 0.32
CC = observed double recombinant frequency/expected double recombinant frequency
We already know the value of CC, and we know how to calculate the observed double recombinant frequency. But we need to calculate the expected double recombinant frequency. So,
0.32 = (3/500)/(RF-RI x RF-RII)
0.32 = 0.006 / (RF-RI x RF-RII)
(RF-RI x RF-RII) = 0.006/0.32 = 0.01875
We know that the expected double recombinant frequency is the recombination frequency in region I multiplied by recombination frequency in region II. In this case, it equals 0.01875
We also know that there are equal distances between genes, so now we need to divide 0.01875 by 2
0.01875 /2 = 0.009375
The genetic distance will result from multiplying that frequency by 100 and expressing it in map units (MU) or centiMorgans (cM). Now we must multiply each recombination frequency by 100 to get the genetic distance
0.009375 x 100 = 0.9375 MU or cM

Lactic acid fermentation is a type of anaerobic respiration that occurs in organisms such as:
1) Bacterial Cells
2) Animals
3) Yeast Cells (fungi)
4) Plants
Answer:
animals
Explanation:
lactic acid fermentation occurs when there is not enough oxygen to make aerobic respiration. glucose will be converted into pyruvates and those pyruvates will become lactates to reduce NADH to NAD+
Lactic acid fermentation is a type of anaerobic respiration that occurs in organisms such as bacterial cells.
What is anaerobic respiration?The term "anaerobic" means "without oxygen". There is no need for oxygen in this type of cellular respiration to produce energy. Smaller creatures require energy to survive in the lack of oxygen since there is not enough oxygen available for them to breathe.They engage in anaerobic respiration, which they use to generate the energy they require.What is lactic acid fermentation?Lactic acid fermentation is a metabolic process that converts one molecule of glucose to two molecules of lactic acid. It occurs in the cytoplasm of the cell.Bacteria convert pyruvic acid into lactic acid when anaerobic conditions, or conditions without oxygen, exist. Not much energy is released throughout this process.

EXplain why a complex food web is better than a simple food chain for the survival of the community.
Answer:
A complex food web is better than the simple food chain because the food web links together the relationships between a producer, consumer, and decomposers. Another reason why a complex food web is better than a simple food chain is that if a particular species is eliminated from a food web, the entire ecosystem has a lower chance of collapsing due to that loss. A food web can more readily react to changes in the environment that impact one or more species.
Hope this helps :)
Answer:
(Answers may vary.)
A complex food web is more important than a simple food chain for the survival of a community. The food web is more important because it is more intricate and adaptive than a food chain. A community houses many species. These species are dependent on each other for energy and food. So, there are multiple relationships of energy transfer involved.
A food chain is linear, which means that each predator has only one source of food. So the predator is vulnerable if the food source is depleted through disease or a change in environmental conditions. Whereas in a food web, each predator has many food sources. A complex food web provides multiple preys to species at a higher trophic level. As a result, a food web illustrates the feeding relationships between many species at different trophic levels in an ecosystem.
