Answer:
Allopatric speciation occur due to various environmental factors with in the environment.
Explanation:
Speciation occur when two population become so genetically different and the can not interbred to produce fertile off spring. The allopatric speciation occur when population become sepret and diverge over time due to natural selection,genetic drift,and mutation.Genetic drift is the sudden loss of gene from a population which cause the population evolvation. Mutation is also change in the genetic makeup of an individual.Natural selection is the phenomena selected by nature and natural forces are involve to select the trait in a living organism.
There are two types of respiration namely aerobic and anaerobic respiration. Anaerobic respiration requires oxygen while anaerobic respiration does not require oxygen. The products of anaerobic respiration (also referred to as fermentation) in yeast are carbon iv oxide and ethanol. Anaerobic respiration has a range of applications in the society which includes Brewing process (bear making process) in alcohol industry, bread making process( baking) in baking industry.
Answer:
D. Friction
Explanation:
friction is when two materials rub against eachother
The phospholipid bilayer functions mainly as a structural framework for the membrane where the polar heads of the phospholipids tend to orient towards their polar surroundings, preserving the hydrophobic part from any contact with water.
<h3>What are phospholipids?</h3>
They are lipid molecules that have a strongly polar group in addition to the hydrophobic hydrocarbon chain.
<h3>Characteristics of phospholipids</h3>
- The polar heads are oriented towards the aqueous medium (intra and extracellular).
- The hydrophobic tails tend to be oriented towards the lipid medium, that is, inside the bilayer, constituting the membrane matrix.
Therefore, we can conclude that phospholipids, due to their amphipathic nature, tend to orient or organize themselves spontaneously, forming the so-called lipid bilayer.

Answer: A. The gut is positioned directly above the foot
Explanation:
Gastropoda comes from two Greek words: gaster (stomach) and pod (foot). The name refers to the fact that their gut is positioned above the foot.
