not really sure cuz this is biogeography and this not my field, but i think (C) is the correct answer (a biome may include multiple ecosystems that share a smaller climate).

Explain in your own words why a dominant trait is not always a common trait.
taurus [48]

Answer:

Describing a trait as dominant does not mean it is the most common; it means that it is expressed over the recessive trait. For example, tongue rolling is a dominant trait, controlled by the dominant version of a particular gene (R). Individuals with one or two copies of R will exhibit tongue rolling.

What did darwin believe was the primary cause of evolution?
lesya692 [45]

→ Darwin believed that the need to adapt, in similar words, the changes occruing in the environment caused evolution.

The main cause of evolution, according to Darwin, was natural selection. Natural selection is a process in which a group of organisms with certain characteristics survive and thrive, in comparison to other organisms with different characteristics. This idea basically means that having some characteristics makes you suited for an environment.


And how would that ↑ explain Evolution?

Well, evolution is the change in species that occurs during time. But for you to change, there must be a cause for that change, which is none other than the need to survive, reproduce, etc.


→ As mentioned before, not all characteristics are enough to surive, and hopefully the image pasted below will help you.



Hope it helped,

A population of 150 individuals has an allele frequency of 0.2 for the dominant allele (H) and a frequency of 0.8 for the recess
Amanda [17]
Hardy-Weinberg Equation (HW) states that following certain biological tenets or requirements, the total frequency of all homozygous dominant alleles (p) and the total frequency of all homozygous recessive alleles (q) for a gene, account for the total # of alleles for that gene in that HW population, which is 100% or 1.00 as a decimel. So in short: p + q = 1, and additionally (p+q)^2 = 1^2, or 1
So (p+q)(p+q) algebraically works out to p^2 + 2pq + q^2 = 1, where p^2 = genotype frequency of homozygous dominant individuals, 2pq = genotype frequency of heterozygous individuals, and q^2 = genotype frequency of homozygous recessive individuals.
The problem states that Ptotal = 150 individuals, H frequency (p) = 0.2, and h frequency (q) = 0.8.
So homozygous dominant individuals (HH) = p^2 = (0.2)^2 = 0.04 or 4% of 150 --> 6 people
Heterozygous individuals (Hh) = 2pq = 2(0.2)(0.8) = 0.32 or 32% of 150
--> 48 people
And homozygous recessive individuals (hh) = q^2 = (0.8)^2 = 0.64 = 64% of 150 --> 96 people
Hope that helps you to understand how to solve these types of population genetics problems!

The use of scientific name, which follows the rules of a standardized classification system.

<h3>Scientific classification of organisms</h3>

The scientific classification of organisms is known as the taxonomy. This system is used to categorise organisms into seven main divisions which include:

  • Kingdom,

  • Phylum or Division,

  • Class,

  • Order,

  • Family,

  • Genus,

  • Species

This system of naming organisms is accepted internationally. If the first person that named the killer whale used the scientific name which is <em>Orcinus orca,</em> the second person would have understood better.
