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.).
The answer is A, bacteria can move around, use energy, and reproduce just like humans can, the only difference is they're single cell and we're not.
Answer:
Motion
Explanation:
Kinetic particles are always in motion, that should just be the fundamental law of kinetic energy
The appropriate response is vestigial. Identifying with a body part that has turned out to be little and lost its utilization as a result of transformative change. Whales, for instance, have little bones situated in the muscles of their body dividers that are minimal bones of hips and rear appendages.
Answer: A cell is defined as the smallest functional units of the body
Explanation:
These cells are grouped together to form tissues, each of which has a specialised function, example blood, muscles, bone. Different tissues are grouped together to form organs with a special function. For example heart is an organ made up of muscles tissue, connective tissue, nervous tissue and vascular tissue. These tissues work in a coordinated manner and enable the heart to carry out the broader function of pumping blood continuously.
While organs are grouped together to form systems, each of which performs a particular function that maintains the body Internal environment and contribute to the health of the individual. For example the digestive system is responsible for taking in, digesting and absorbing food which involves a number of organs, including the stomach and intestines.
Therefore the statement that 'organs are large structures that keeps us alive" is a correct claim.
