Fertilization is the fusion of gametes to form the zygote. ... Fertilization allows restoring of the chromosome number of the species as the two nuclei of gametes fuse together. Therefore, the number of chromosomes in the zygote is twice the number of chromosomes in gametes.
Explanation:
Answer;
A. A-delta fibers
A-delta fibers transmit pain that is sharp, nonchronic, and well localized.
Explanation;
-The information about touch and pain is transmitted to the spinal cord and brain by primary afferent axons - these are the nerve fibers connected to the different types of receptors in the skin, muscle and internal organs.
-The different nerve fiber groups are; A-alpha, A-beta, A-delta and C-nerve fibers.A-alpha, A-beta and A-delta nerve fibers are insulated with myelin. C-nerve fibers are unmyelinated.
-A-delta nerve fibers carry information related to pain and temperature. A-delta nerve fibers can conduct action potentials as fast as a sprinter in the Olympics.
Chromatin is within the nucleus and is found in BOTH eukarayotic and prokaryotic and is a condensed structure of DNA,proteins, and RNA. It basically protects the DNA sequence and structure. It allows for mitosis and meiosis to happen. The nuclelous is located inside the nucleus but ONLY in eukarayotic cells. It makes ribosomes.
The kidneys are a pair of bean-shaped organs on either side of your spine, below your ribs and behind your belly. Each kidney is about 4 or 5 inches long, roughly the size of a large fist. The kidneys' job is to filter your blood.
Answer:b. microsystem.
Explanation:
The microsystem is one of the component of ecological system theory. The microsystem describes the system, which is close proximity to the person. For example, the interaction of child with the school teachers, classmates, friends, parents and siblings. The person learns a lot through the direct interaction with people. This is like to influence the physical and behavioral outcomes.
