<h3><u>Answer;</u></h3>
<em>Centrioles </em>
<h3><u>Explanation;</u></h3>
- <em><u>Centrioles</u></em> are organelles that are only found in animal cells.
- <u><em>Centrioles are important organelles that functions by helping the process of cell division in animal cells.</em></u> This is by helping the formation of spindle fibers whose role is to separate chromosomes during cell division.
- Additionally, <em><u>centrioles also play a very important role in celiogenesis, the formation of cilia and flagella on the surface of cells.</u></em> The cilia and flagella enhance the movement of cells.
<h3><u>Answer;</u></h3>
white eyes are homozygous recessive
<h3><u>Explanation</u>;</h3>
- <em><u>Thomas Hunt Morgan work with the fruit fly showed that genes are linked in a series on chromosomes and are responsible for identifiable, hereditary traits. </u></em>He was the first to identify that genes are linked to the same chromosome.
- <em><u>According to his hypothesis he stated that genes that are linked are arranged linearly on a chromosome, while those genes with low combination frequencies must be closer together and thus difficult to separate</u></em>.
- When a gene contains two similar alleles that is, either two dominant alleles or two recessive alleles then it is called homozygous dominant and homozygous recessive respectively. White eyes of a fruit fly is an example of homozygous recessive
Answer:
Carbon dioxide
Explanation:
The carbon combines with oxygen to form carbon dioxide (CO2) and is released back into the atmosphere as a waste product when animals breathe and exhale.
Answer:
The correct answer is C. A buildup of lactic acid in the tissues.
Sore muscles after vigorous exercise are the result of lactic acid accumulation in the muscles.
Vigorous exercise reduces the levels of oxygen available in the muscles due to which complete oxidation of the glucose could not take place.
Muscle cells switch to another process called as lactic acid fermentation to produce energy. In this process, lactate dehydrogenase converts pyruvate into lactate and reduces NADH to NAD⁺.
This NAD⁺ enables the continuation of glycolysis which results in the production of net 2 ATP.
In addition, influx of materials such as nutrients, WBC, anti-inflammatory compounds etc into the muscle cell (for repair) causes swelling of the muscle fibers which is also the reason for the muscle soreness.
