A swimmer dives underwater and needs to swim a long distance while holding her breath. This prevents her body from getting oxygen.
What is most likely to occur in her cells so that glycolysis can continue to produce ATP?
a) cellular respiration
b) alcohol synthesis
c) lactic acid fermentation
d) alcohol fermentation
Answer:
C is the correct option.
Explanation:
Cells in the body continue to produce ATP in absence of oxygen.
Lactic acid fermentation is most likely to occur in the swimmer's cells so that the process of glycolysis can continue to produce ATP. Thus, the correct option is C.
What is Lactic acid fermentation?
Lactic acid fermentation is a metabolic process in which glucose or other six-carbon sugars are converted into cellular energy (ATP) and the metabolite lactic acid. It is an anaerobic fermentation reaction which occurs in some bacteria and animal cells, such as muscle cells and in absence of oxygen molecule.
Lactic acid fermentation happens in the skeletal muscles. In this process, pyruvate is converted to lactic acid by the lactate dehydrogenase enzyme when oxygen is inadequate. Fatigue is brought on by the formation of lactic acid which buildup in the muscles.
Therefore, the correct option is C.

If a cell crossed over one time during Prophase I of Meiosis, how
many genetically distinct gametes would be produced?
Answer:
If crossing over doesn’t occur, then 2 out of the 4 daughter cells would be identical.
We have 46 chromosomes and are diploid meaning we got 1 set (23 chromosomes) from our mom and 1 set (23 chromosomes) from our dad.
In prophase 1, homologous chromosomes associate (chromosome #1 from dad and chromosome #1 from mom. They both code for the same things, but they are NOT identical)
Let’s compare mitosis to meiosis
On the left, see how in mitosis all chromosomes (even homologous) line up in single file (imagine all 46 lining up individually). When anaphase splits the sister chromatids (which are identical) in mitosis, each daughter cell gets the exact same genetic info.
(they get both homologous chromosomes: 1 from dad (yellow)and 1 from mom (purple) resulting in a full diploid set)
On the right in meiosis, see how the homologous chromosomes associate and will split? Chromosome #1 from mom (purple) is going to the left daughter cell while chromosome #1 from dad (yellow) is going to the right daughter cell. This means the two daughter cells will only have 1 set for chromosome #1 (either moms or dads but NOT both) and become haploid (1 set of 23 chromosomes)
Again in mitosis, all 46 lined up individually, but in meiosis the 23 from mom and 23 from dad first associate and each orient to decide which daughter cell gets the dads chromosome or the moms chromosome. They assort independently meaning just because dads chromosome #1 went to the left DOESN’T mean that dads chromosome #2 or #3 will go to the left. This gives a unique pattern of 23 chromosomes for the 2 daughter cells of meiosis 1 (a various mixture of moms and dads, but it is possible to result in a daughter cell with just moms and just dads set, though this would be a very small probability like 1 in 2^23 )
So each daughter cell of meiosis 1 is a haploid set (only 1 set instead of 2) and the opposite of the other (since 1 has fathers while the other has mothers for the same chromosome)
Meiosis 2 is just like mitosis. Here the sister chromatids separate producing 2 identical daughter cells
(identical if crossing over doesn’t occur. Crossing over only occurs on adjacent homologous chromatids)
If crossing over doesn’t occur then both sister chromatids are identical so that 2 out of 4 daughter cells will be exactly identical haploid sets. The other 2 are identical to each other as well.
Explanation:
Answer:
please give me brainlist and follow
Explanation:
Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.

Cattle and other ruminants have evolved to eat grass. What problem has emerged as a result of feeding
corn to cattle instead?
Explanation:
Since corn was very cheap, the farmers raised cattle on corn also believing that the cows would gain more weight, therefore, more product or supply for them to sell. However, this resulted in the cows begin developing a disease called E. Coli, which then leads to social issues.
Answer:
the cattle are more on a risk of health diseases
Explanation:
because corn has nutrients but not enough of each to provide the cattle the nutrients it needs

Explanation:
The DNA is doble stranded in a double helix structure. There are 5 nucleobases (adenine (A), cytosine (C), guanine (G), thymine (T), and uracil(U)), only the first 4 are present in the DNA whilist the U substitutes the T in RNA.
The DNA has deoxyribose sugar while RNA has ribose sugar, that's what gives the doble stranded and single stranded form respectively.

a.
The populations of the other three species would also increase.
b.
The populations of the other three species would decrease.
c.
The grass population would decrease. The snake population and hawk population would increase.
d.
The grass population and hawk population would decrease. The snake population would increase.
Please select the best answer from the choices provided
A
B
C
D
Answer:
she is wrong , its c
Explanation:
The grass population would decrease. The snake population and hawk population would increase.
The correct answer is option C. . If you were to suddenly double the population of rabbits, the grass population would decrease due to overgrazing by the increased rabbit population.
What will happen in result to it ?As a result, the snake population and hawk population would increase due to the increased availability of prey. This is known as a trophic cascade, where changes in one trophic level affect the populations of other trophic levels in the food chain.
Option A and B are unlikely as doubling the population of rabbits would not necessarily cause the populations of the other three species to increase or decrease in a straightforward manner.
Option D is incorrect as there is no direct relationship between the rabbit population and the hawk population in this food chain.

What is the function of each lymph organ?
Explanation:
The main role of the lymphatic system is the transport of cells of the immune system during the activation of immunity, lipids in the form of lipoproteins, as well as the introduction into the systemic circulation of various objects (small and large molecules, liquids, infectious agents, etc.), packed in delivery vehicles - exosomes and vesicles
The main role of the lymphatic system is the transport of cells of the immune system during the activation of immunity, lipids in the form of lipoproteins.
What is lipoprotein?Particles called lipoproteins are comprised of protein and fat (lipids). They deliver cholesterol to your cells through your bloodstream.
High-density lipoprotein, or "good" cholesterol, and low-density lipoprotein, or "bad" cholesterol, are the two main categories of lipoproteins.
LDL comes in the form of lipoprotein. These lipoproteins transport cholesterol to the artery cells. High levels of LDL particles can cause cholesterol to accumulate in your arteries and create blockages known as plaques. The term "hardening of the arteries" or atherosclerosis refers to this condition.
Therefore, The main role of the lymphatic system is the transport of cells of the immune system during the activation of immunity, lipids in the form of lipoproteins.

to which part of a dna molecule are nucleotides added?
Answer:
Nucleotides are exclusively added to the 3' end of the developing strand when DNA is produced in the 5'-to-3' orientation. The 5'-phosphate group of the new nucleotide attaches to the 3'-OH group of the final nucleotide of the developing strand.
At the 3' end of the deoxyribose sugar, an upcoming nucleotide is added. The existing nucleotide's 3'-OH end and the new nucleotide's 5' phosphate make a phosphodiester bond. In this way, new nucleotides are added.
How does DNA polymerize?
The DNA is made up of nucleotides. Each nucleotide of DNA is made up of a deoxyribose sugar, a phosphate group, and a nitrogenous base. Nitrogenous bases include adenine, guanine, cytosine, and thymine. The sugar of the DNA has a lack of oxygen at the 2' end. A glycosidic bond connects the sugar's 1' end to the nitrogen base.
The 5' end of sugar is attached to the phosphate group. The 3' end of sugar is attached to the 5' phosphate of the new upcoming nucleotide. A phosphodiester bond is formed during the addition of new nucleotides. Two phosphate groups of the new nucleotides are removed. Example: If ATP comes, then it will make AMP and attach to the DNA chain.
Hence, at the 3' -OH end of sugar of the existing nucleotides, a new one is added.
