Is this a true or false question? if so, the answer would be false because adrenaline increases your heart rate, evolution is how things grow and change over periods of time.
There are many types of frogs thus there are a lot of scientific names also, such as Rana draytonii or Atelopus zeleki. But the common scientific name or order for frogs is called Anura.
Answer:
B. an amino terminal signal peptide
Explanation:
The reactions of the citric acid cycle occur in the matrix of mitochondria. Therefore, all the enzymes required for this pathway are present in the matrix of mitochondria. These enzymes are formed on the ribosomes present in the cytosol and are transported into the mitochondria with the help of cytosolic heat shock proteins. The newly formed mitochondrial proteins have signal sequences present at their N terminal. The proteins to be transported into the matrix have a single signal sequence that at N terminal which is removed by a protease once the enzyme enters into the matrix.
Based on the information in the question, we can infer that the question being asked is most likely "<u><em>What mechanisms do fish use to maintain homeostasis in salt-water environments</em></u>?".
<h3>What is homeostasis?</h3>
- Homeostasis is a series of regulatory processes by which an organism <em><u>maintains core values (or range of values) necessary for everyday life.</u></em>
<em><u /></em>
<h3>How to test the question</h3>
- The question is in the form of a hypothesis.
- This means that the scientist must first propose a possible solution to the question.
- Then, the scientist will make observations based on this question.
- In this case, it would seem the scientist has placed the fish into an environment <em><u>that differs from its natural habitat, in order to observe how the fish maintains homeostasis. </u></em>
Therefore, we can infer that the most likely question being asked is in regards to the way in which fish maintain homeostasis.

Answer: False.
Meat is a good source of protein. There are nine essential amino acids which are required under special conditions like illness.
These are- Histidine, Leucine, Isoleucine, Valine, Threonine, Methionine, Lysine, Phenylalanine and Tryptophan. They cannot be synthesized by the body and therefore need to be taken from external protein sources.
Since meat contains all the essential amino acids, therefore it is considered as a good source of protein. Hence, the given statement is false.
