The US population most closely represents a clumped pattern, as humans are social animals who interact regularly. The United States has higher populations near major cities, which generally have more resources than rural areas.
The correct answer is mouth of a river
That's where the river slows down and particles start sedimenting. When the sediment is huge, deltas are formed.
Answer:
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
<h2>Answer</h2>
The fact that many human traits are determined by a combination of genetic and environmental factors is referred to as multifactorial transmission.
<u>Explanation </u>
Multifactorial transmission that is determined by a connectivity of genetic and environmental fact is defined as, many factors which are concerned in generating a delivery error. The factors are mostly transmitted and the environment in which there is a blend of genes of parents male and female both. it also can be said that hidden environmental factors contribute to the characteristics and creates a condition.
A mutation in the HBB gene can cause the formation of haemoglobin S (HbS) which leads to sickle cell disease. So, in this case the mutation is harmful. On the other hand, people who are heterozygous for the mutant allele are resistant to malaria and in this case mutation is beneficial.
A mutation in EYC3 gene is neutral, because the change of eye color is either beneficial or harmful.
A mutation in CFTR gene is harmful, because malformed CFTR protein can't perform its key function in the cell. As a result, the balance of Cl and fluids is disrupted, causing mucus in various organs to become thick and sticky.
A mutation in LRP5 causes high bone mass and consequently, many bone density related diseases. So, this mutation is harmful.
