<u>Answer</u>: A) They have been geographically isolated from each other for a longer time.
<u>Explanation</u>: An isthmus is defined as a narrow strip of land that separates two bodies of water as well as connecting two larger landmasses at the same time. Thus, an isthmus if an efficient physical barrier that has separated an original shrimp species. This has resulted in the extant deep-water shrimp species through the evolutionary process known as allopatric speciation.
The age of an isthmus is in the range of at least two million years. Thus, the two deep-water shrimp species have been separated from each other for a very long time.
Answer:
Option-3
Explanation:
Collagen is one of the most abundant proteins of the animal kingdom as it is present in the connective tissue.
The collagen protein undergoes glycosylation that is carbohydrate molecules are attached to the protein.
The collagen fiber is produced by the chondroblasts which are suspended in the extracellular matrix of the cell. These fibers provide strength and flexibility to connective tissue.
Thus, Option-3 is the correct answer.Answer:
<span>The nurse's priority is to assess the patient, including vital signs. If the nurse detects that the labor is progressing, she should notify the physician. She should also determine whether the patient is due for pain medication and determine what she is able to give at that time period.</span>
Answer:
a. glycolysis—preparatory reaction--cirtric acid cycle--electron transport system
Explanation:
- Glycolysis is the first stage of cellular respiration that occurs in the cytoplasm of the cell. During glycolysis one 6 carbon glucose is converted into two molecules of 3 carbon pyruvic acid or pyruvate.
- In the preparatory reaction, the pyruvate converted into a two-carbon molecule called acetyl CoA. In this reaction, a carbon dioxide molecule is released and a molecule of NADH is released.
- The citric acid cycle begins with the reaction of the acetyl CoA with a four-carbon molecule in the mitochondrisl matrix. It goes through a cycle of reactions regenerating the four-carbon starting molecule. ATP, NADH and FADH₂ are produced.
- The electron transport system is the terminal step of aerobic respiration that operates on the inner membrane of the mitochondria. Reduced coenzymes NADH and FADH₂ move along electron transport system release high-energy electrons and produce ATP.
