Answer:
e, both A and C
Explanation:
The lytic life cycle ends when the virus load is expelled from the host cell. But, to be released, the virus have to escape from the host cell's plastic membrane, usually by changing the osmotic change, and making it explode.
This releases the viruses into the extracellular matrix, allowing them to infect other tissue cells.
Vasoconstriction
Definition-The blood vessels under your skin become narrower. This decreases blood flow to your skin, retaining heat near the warm inner body.
Answer:
C. Synthesis of organic molecules
Explanation:
According to chemical evolution theory, life originated from inorganic molecules by the mode of chemical evolution. In primitive conditions of earth, only inorganic molecules were present. These molecules reacted under lightning, UV radiation and other environmental conditions to give rise to complex organic molecules like amino acids, sugars, lipids etc. They formed the basis for proteins, RNA and other molecules which ultimately led to the formation of cellular structures.
Answer:
E. It takes a picture of the brain according to oxygen levels. More oxygen in an area indicates more activity in that area.
Explanation:
Haemoglobin is diamagnetic when oxygenated but paramagnetic when deoxygenated. This distinction in magnetic characteristics leads to tiny variations in the blood MR signal. Since blood oxygenation differs, these variations can be used to identify brain activity depending on the concentrations of neural activity.
A community is where a group of people live really close by vs. a population counts how many people live in a area
