Answer:
The correct answer would be meiosis.
In diploid organisms, meiosis is the process that results in the formation of four haploid daughter cells from single diploid parent cell. Each of the daughter cell contains half the number of chromosomes present in parent cell.
It results in the formation of haploid gametes (sperm in males and eggs in females) which is essential in the process of sexual reproduction.
The fusion of gametes results in the formation of diploid zygote that is, maintains the diploid nature of the organism.
Hence, in absence of meiotic division the chromosomal number would keep on doubling after each generation.
In addition, crossing over (exchange of genetic material between non-sister chromatids) also takes in the prophase-I of meiosis I. It increases the genetic variation within organisms of the species. It may add survival adaptations to the population.
Answer:
a. surrounds individual muscles.
Explanation:
Individual muscle fibers have layers of connective tissue surrounding them. Epimysium, perimysium, and endomysium are the three layers of connective tissue that extend from the fascia and protect the muscle fibers. Epimysium is the outer most layer of connective tissue of individual muscle fiber. It encircles the entire muscle. Epimysium consists of dense irregular connective tissue. It serves to separate the muscle fibers from the other types of tissues present in the area to facilitate their independent movement.
Answer:The sequence of the nucleotides along the backbone encodes genetic information
Explanation:
The peripheral nervous system receives information from the environment and relays commands from the central nervous system to organs and glands.
<h3>What is the peripheral nervous system?</h3>
The nerves that emerge from the brain and spinal cord make up the peripheral nervous system. The CNS and the body components are connected through a network of nerves. The somatic nervous system and the autonomic nervous system are additional divisions of the peripheral nervous system.
The somatic nervous system and the autonomic nervous system are two subsystems of the peripheral nervous system. With the exception of the optic nerve (cranial nerve II) and the retina, the cranial nerves make up the PNS in the somatic nervous system. The second cranial nerve is a tract of the diencephalon and not a real peripheral nerve. The CNS is where the cranial nerve ganglia were born. The PNS, however, is thought to include the ten remaining cranial nerve axons because they travel outside of the brain. Smooth muscle and glands are subject to involuntary control by the autonomic nervous system. The sympathetic and parasympathetic states of the system are made possible by the relationship between the central nervous system and the organs.

The answer to this is multicellular. Unicellular organisms' life processes all take place in the one cell which is their entire being - their entire existence - whereas multicellular organisms require specialized organs and organ systems to keep us alive.
