I disagree with this statement. Asexual organisms are at a lower risk for extinction due to the fact that they do not need a partner to procreate. They have an easier time making offspring.
Water is attracted to ions, such as sodium, potassium, phosphate, and chloride ions. Maintenance of normal intracellular fluid volume depends largely on the intracellular concentration of potassium and phosphate ions. Maintenance of extracellular water volume on the other hand depends primarily on the extracellular concentration of sodium and chloride ions.
Answer: unfavourable ph condition for the pepsin
Explanation: during digestion, enzymes are needed to aid the process.digestive enzymes are biological catalyst that breakdown large food particles into digestible form .
As biological catalyst, enzymes require an optimum temperature and pH condition.outside this temperature or pH,the enzyme is denatured.
In the stomach, hydrochloric acid is required to convert pepsinogen into it's active form,pepsin.the acid also creates an optimum low pH that pepsin needs to function.
As the food moves to the small intestine,the pH is alkaline and is unfavourable for pepsin to function.
Just as animals, plants also contain vascular<span> tissues (</span>xylem<span>), which transports water and minerals up from the roots to the leaves, and </span>phloem<span>, which transports sugar molecules, amino acids, and hormones both up and down through the plant</span>
Answer:
They are used to transport electron during metabolic reaction.
