Answer:
First question - Green curve
Second question - Red curve
Explanation:
Answer:
homologous structure
analogous structure
natural selection
This is known as an analogous structure.
To make this determination, you need to think about if the features are the same in function or also in structure. Features that have a closely related structure and function are likely to be related.
To learn more about why your friend is in the hospital, you should research vestigial structures.
These two beetles aren't closely related, but they look and behave similarly. This is because they live in the same environmental conditions and likely share a common ancestor that lived in Gondwana (the supercontinent that included the southern continents before they split apart through plate tectonics).
Australia has so many genetically distinct organisms because it has been separated from other bodies of land by water for a very long time. This has created an opportunity for long-term independence of other geographic areas.

Hey there!
Here is your answer:
Since there are not options im going to go with what i know:
<u>(Alleles)</u>
<span><u>heterozygous: A,a</u>
</span><u>homozygous: a,a</u>
<u>Therefore the Punnett square should look like this:</u>
<u>A, a</u>
<u>a IA,a I a,a</u>
<u>a IA, a I a, a</u>
Therefore the answer is 50% A,a , and 50% a, a!

Answer:
1. DDT (
Dichlorodiphenyltrichloroethane) with molecular formula; C14H9Cl5
2. Lead
Explanation:
1. DDT (Dichlorodiphenyltrichloroethane) is an example of compounds that biomagnifies in the biosphere. DDT is used as pesticides. When DDT is sprayed on plants to kill their pests, part of it is accumulated within the plants.
However, when primary consumers feeds on the affected plants, DDT is passed on to them and then to the secondary consumer in that sequence until it get to the top of the trophic level.
Effects of DDT have been seen in many organisms including birds and humans. The effects seen in humans is quite minimal to that of insects and birds. DDT causes lost of many insects and young birds. In humans, it causes vomiting, seizures etc.
2. Lead: it enters the biosphere by absorption and consumption means. Humans through the use of lead paint, smoking of cigarettes, use of cosmetics and combustion of coal accumulates lead in their bodies. Lead can't be synthesize by human, therefore it accumulates and biomagnify within their systems.
The effects of lead in human include; vomiting, stroke and abdominal pains. In tough scenario, it causes immune system deterioration and cardiovascular diseases.
