Answer:
b. synthesis of cellular membrane components
Explanation:
Endoplasmic reticulum is a network of membranes fistulas; within the cytoplasm of a eukaryotic cells, where proteins and lipids are synthesized usually connected in continuum with the nuclear membrane of the cell.
The ER is of two kinds the smooth and the rough ER (Endoplasmic reticulum).
Functions of Rough endoplasmic reticulum includes; * Synthesis of protein * Degradation of worn out organelles
While the functions of Smooth endoplasmic reticulum includes; * Synthesis of lipid and steroids * Role cellular metabolism * Storage and metabolism of calcium * Catabolism of toxic substance.
Inference from the functions stated above shows that ER is actively involved in the synthesis of cellular membrane components.
a. new source of fresh water <span>
Other choices are:
</span>
<span><span>b. less access to medicine </span>
<span>c. a higher birthrate </span>
d. a higher fertility rate
New source of fresh water </span>would most likely increase the carrying capacity for humans in a certain region. Water plays many important roles in the ecological and environmental systems, and also in humans. In cellular activities and organismic activities, water is used primarily.
For example,
Water is produce when glucose and fructose undergo a condensation process. The water is removed by the combination of hydrogen and a hydroxyl together. Glucose and Fructose forms a substance called glycosidic linkage. And hydrogen and hydroxyl is separated from glucose and fructose. When Hydrogen and hydroxyl is combined, they create H2o or water.<span> </span>

Answer: The correct answer is A
Explanation:
This because in space there is microgravity I.e absence or less gravity, the astronaut do not need to do much work, just to sleep, eat and go around. In microgravity the muscles are prone to atropy( respons e to gravity) which causes the muscle to be stiffen and straighten out, the muscles becomes weak.
