Answer:
Explanation:
In endoplasmic reticulum, many folds leads to an increase in surface area for ribosomes to attach which allows for protein synthesis to occur at an efficient rate.
mitochondria has two membrane,
It has an inner membrane which is folded inside the other. The fold create cristae, which is the site for a portion of cellular respiration.
The folds also enables a large surface area that makes chemical process to occur in an efficient way.
The correct option is (D) iteroparous; K -selected
Iteroparous organisms are the organisms that reproduce multiple times.
<h3>
What is Semelparity and Iteroparity?</h3>
- Semelparity and iteroparity are the two different reproductive strategies available to living beings.
- Iteroparous species have multiple reproductive cycles throughout their lifetimes, while semelparous species have just one reproductive cycle before they die.
- Death that occurs after reproduction is part of a bigger strategy in really semelparous animals that also entails maximizing reproduction at the expense of future survival.
- There will always be some iteroparous individuals who die between their first and second reproductive episodes, but unless they exhibit symptoms of a state of programmed death after reproduction, they are not termed semelparous.

Similarities and differences are explained below
Explanation:
Differences:
somatic nervous system:
- It is part of the peripheral nervous system associated with the voluntary control of body movements through the skeletal muscles and mediation of involuntary reflex arcs.
- It has sensory and motor pathways.
- It controls muscles and movement.
- System responses are based on skeletal muscle contraction.
Autonomic nervous system:
- The autonomic nervous system is subdivided into the sympathetic nervous system and parasympathetic nervous system
- It possesses only motor pathways.
- It controls glands and internal organs.
- This system works automatically, without a person's conscious effort.
Similarities between the somatic nervous system and the autonomic nervous system:
Both have motor pathways
Both the system use nerve impulse
Both the system Weaken Myocytes
Both the system use glucose as an energy source for the muscles that they control
Both the system are controlled by the CNS
Both possess neurons
Answer:
The two main variables in an experiment are the independent and dependent variable. An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment.
After the completion of first trimester that is 8 weeks of conception, the baby is almost 1 inch grown. At this stage, the baby is referred as fetus. At this stage, all the organs as well as limbs becomes visible except for the sex organs.
The heart of baby beats rhythmically. Eyes and the eyelids are completely visible. Both the forelimbs and the hind limbs are formed, and fingers buds are also visible.
At this stage, the fetus looks like a human. The umbilical cord is also clearly visible at this stage.
Hence, the correct answer is 8th week.
