Answer:
A. a developing nation
Explanation:
Age pyramids are the age structure diagrams that represent the number and proportion of people at each age in a population. The base of the age pyramids represents the population in pre-reproductive age which is from 0 to 10 years. The overall shape of an age pyramid indicates if the population is increasing, stationary, or shrinking.
The age structure diagram for a developing nation has a broad base that tapers quickly towards the top. This means that a larger percentage of the population is in the pre-reproductive age group and reproductive age group with a smaller percentage of the population in the post-reproductive age. These countries have a great chance of future population growth.
Answer:
tRNA molecules bring a specific amino acid to the ribosome, according to the mRNA codon.
Explanation:
In the context of protein synthesis, an mRNA molecule contains the specific codons that encode the amino acids that will be part of the protein. The tRNA is in charge of bringing the amino acids to the ribosome, according to the specific information of the mRNA codons.
Answer:
A. Skeletal muscles
Explanation:
An effector is a group of cells, an organ, gland or any part of the body that acts to bring about a change in response to a nerve impulse from the CNS.
In the case of thermogenesis as stated in the question above, where a drop in temperature is detected by thermoreceptors in the CNS, the part of the body that responds in returning the body temperature back to its baseline are the skeletal muscles. The skeletal muscles are the effectors that responded in repeated contracions to generate heat.
<span>The condition of not being able to speak is called aphasia. Aphasia is an inability to comprehend language because of damage brain caused by the low supply of blood to the brain. People having this may not just lose their ability to speak but also the ability to read and write. </span>
Answer:
The correct pair is -'d' that is nuclear accumbens-reward.
Explanation:
The location of nuclear accumbens is the basal region of fore brain.This is the part of basal ganglia.
This is an important part of ventral striatum along with dorsal striatum which from the basal ganglia.
The main structure of nuclear accumbens are core and shell.
The shell region is also called as NAcc shell is located in the outer region of the nuclear accumbens also called as dorsal amygdala.
The core region NAcc core is located in the inner region of the nuclear accumbens and considered to be a part of basal ganglia.
This region control the reward and punishment centers that are present in the brain. This contain another function which is associated with psychotic problem such as depression, addiction and ablation etc.
