Various factors influences the fluidity of the phospholipid bilayer of the cell membrane. If we were to chart the composition of
mote1985 [20]

Answer:

D

an increase in the length of the fatty acid tails.

Explanation:

As average annual temperatures decrease, we would expect to find phospholipids within the cell membranes of organisms to have both saturated

and unsaturated fatty acid tails. Saturated fatty acids tails are arranged linearly, in a way that maximizes interactions between the tails and

decreases bilayer fluidity. Unsaturated fatty acids, on the other hand, have more distance between the tails, fewer intermolecular interactions and

more membrane fluidity. Longer tails and decreased cholesterol also decrease fluidity

What is the part of the nervous system that receives information about what is happening within the body and in the outside envi
Alecsey [184]

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.

r-ruslan [8.4K]

Answer:

mitochondria  

Explanation:

Mitochondria are organelles found in eukaryotic cells that are capable of generating the main part of the energy required for the cellular biochemical reactions. In addition, mitochondria are also involved in distinct biological functions including, among others, cell signaling, death, differentiation and growth. It is believed that mitochondria evolved from prokaryotic organisms which introduced inside others to form eukaryotic cells, this theory is known as the 'endosymbiotic theory'.

asambeis [7]

Answer:

d. No longer dividing cells of the mammalian brain

Explanation:

Cell cycle consists of events that lead to the duplication of DNA and division of cell into two daughter cells. It occurs in the zygote to make more cells for building an organism. It also occurs in skin, blood and other internal organs for self renewal.

It consists of G1, S, G2 and M phase. DNA replication occurs in S phase of cell which means that it is in the process of dividing. No longer dividing cells of mammalian brain have exited the cell cycle and are in resting phase which is also called as G0. They cant form new cells hence wont have DNA replication. Thus, these cells would be least likely to contain cells in S phase.
