Answer:
a. the rough endoplasmic reticulum
Because it is the site of protein synthesis.
and all of the other organelles have no relation to protein and handling especially peroxisomes which detoxifies h202 and helps with intracellular digestion similar to the lysosomes and microtubules only function is for locomotion of prokaryotic cells and some eukaryotic cells like the sperm cell also they make up spindle fibers used to bind and separate chromosomes/chromatids in mitosis and meiosis.
Answer:
The environment plays a role in a mutant allele in a population because some mutations are more beneficial to the organism than other mutations.
Explanation:
Organisms with a beneficial allele mutation will be able to pass on their genes as they reproduce. The mutation makes them <em>fit</em> for survival in their environment. Other organisms <em>without </em>the beneficial allele won't be able to pass on their genes since it will be more difficult for them to survive in their environment. Natural selection will deem that the organisms with the mutation will survive better and be able to produce offspring with the same mutation.
Answer
Wind may be involved in the formation of sandstone arches by facilitating erosion which wore away exposed sections of rocks and enlarges the cracks on the surface forming marrow sandstone fins.
Explanation
Sandstone arches can be formed when a large piece of sandstone flaked off as a result of high winds. In addition to that, alternative frost and thawing can result into crumbling of porous sandstone which will in the long run cut through some fins. These resulting holes enlarge to form arches with effects of weathering and rock fall caused by wind.
Frog temperature. Frogs are ectotherms, this means they gettheir heat from external sources. They are sometimes called 'cold blooded', but in fact they do not have cold blood, it is justregulated by their environment. In comparison, humans are endotherms and can maintain their body temperature at about 37°C.
