They are different because endocrine glands has tiny amount of hormone directly into the bloodstream . While exocrine glands secret their products on to epithelial
When organisms leave the group they were born into and join another group, this can alter allele frequencies in the new group. This mechanism is called gene flow.
Allele frequency is a relative term that tells about the frequency of an allele in a population. To calculate allele frequency, the total number of allele of interest is divided by the total number of all the alleles present in that population.
Gene flow is the movement of the genes. It can move into a population or move away from the population. This results in change in the total gene pool of a small population. The migration can either ne natural or forced.

Answer:
Enzymes acts as catalysts to speed up chemical reactions.
Explanation:
Enzymes are otherwise known as biological catalysts which means that the help speed up reactions and break down large food molecules.
Answer:
1) The correct answer would be A. it transfers carbon to the atmosphere as carbon dioxide.
Cellular respiration refers to the set of biochemical reactions take place in a cell in order to convert the energy of glucose into adenosine triphosphate (ATP).
The carbon dioxide is released as the byproduct of the process.
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP
2) The correct answer would be D. fermentation can occur without oxygen.
Fermentation is the process which occurs in oxygen is either absent or present in very less amount.
Thus, it enables the cell to survive when oxygen is not available.
For example, in humans, the muscle cells switch to lactic acid fermentation when oxygen supply is decreased during intense exercise.
It produces very less amount of ATP as compared to the aerobic respiration.
