lungs or ribs that separate the two upper chambers from each other
Answer:
Gills allow for gas exchange
Explanation:
<span>The correct answer is d. the idea that T. rex held its tail aloft was supported by the studies of many scientists. This is how science works, things are discovered by having members of the scientific community do experiments and come to the same conclusion. Many of them confirmed this theory and a concensus was established.</span>
Answer:
The correct answer is ''Translocation.''
Explanation:
Translocation is a chromosomal abnormality that is due to a change in position of a chromosomal segment to another non-homologous chromosome of the same nucleus or to another part of it. It is produced by the exchange of segments between two chromosomes without loss of genetic material is called reciprocal or balanced translocation, when it gives rise to monocentric chromosomes.Translocations can be detected cytologically because the structural heterozygote forms a quadrivalent (4-chromosome association) in meiotic prophase. Sometimes they can also be detected by changes in the size of the chromosomes if the exchanged segments are of different lengths.
Answer:
Hypotheis:
<em>If high amounts of product in the samples, '+++' , correlates with optimal temperatures and pH for enzyme activity, then...</em>
- <u>A- Pepsin</u>
- <u>B- Amylase </u>
- <u> C- thermophilic enzyme</u>
Explanation:
Enzymes are specialized proteins that function as biological catalysts- <u>they speed up chemical reactions.</u> As proteins, these are susceptible to changes in temperature and pH- they function best at optimal values for both conditions, but can be denatured, rendering them inactive at relative extremes.
Each enzyme provided has its own optimal temperature and pH values.
- Thermophilic enzymes are usually found in regions characterized by high temperatures. They show high thermostability, and do not become denatured at high temperatures- they thrive, and do not function well at lower temperatures.
- Amylase is a hydrolase digestive enzyme found in the mouth, that acts on polysaccharides like starch to break 1,4 glycosidic bonds between glucose molecules. It works best at a physiological (neutral) pH and temperatures (around 37°)
- Pepsin, another digestive enzyme, is a peptidase that breaks down proteins into peptide molecules. It is found in the stomach lining, where the pH is typically low i.e. acidic due to the hydrochloric acid in digestive juices.
Thus from the table A- pepsin, B- Amylase and C- thermophilic enzyme can be hypothesized.
