The symbiosis between a Pistol shrimps and gobies is called Mutual symbiosis. <u>In this process both animals benefit. </u>The shrimp creates and maintains a burrow for both the animals to live in, where as the fish offers protection from predators. When outside of their burrow the fish keeps a keen eye to spot any predator around and sends a warning to the goby through flicking of its tail in cases of a predator approaching.
The given blank can be filled with enzymatic molecules.
Enzymes refer to biological molecules or proteins, which function as catalysts and assist the composite reactions to take place everywhere in life. The enzymes generally end with the suffix - ase. For example, proteases, which functions to dissociate the peptide bonds between the amino acids.
Enzymes are big molecules, which accelerate the rate of chemical reactions within the cells, and like all other kinds of proteins, they comprise lengthy chains of amino acids.
Answer:
Testes and ovaries produce two types of hormones:
androgens (male sex hormones)
estrogens (female full hormones)
In each type of gland, both types of hormones are secreted only in different amounts: the ovaries secrete more estrogen than the androgen hormones, and the sperm inversely.
Explanation:
In testicular tissue, Leydig cells produce androgen hormones: androsterone and testosterone. The ovaries produce a group of estrogen hormones and progesterone. These hormones exert their effect at puberty when the glands are activated. At puberty, the pituitary gonadostimulins activate the sex glands, whose activity leads to the development of secondary sex characteristics (the appearance of first menstruation in girls, beards and mustaches in boys, etc.).
Primates refer to mammals characterized by there large brain and complex behavior. Non - primates refer to any animal that’s not a mammal
