What is the creation of new combinations of alleles called?
gene flow
mutation
recombination
genetic drift
Genetic recombination is the interchange of genetic material across organisms, resulting in offspring with unique features. Therefore, option (C) is correct.
What is recombination?The exchange of genetic material between distinct species, or genetic recombination, produces offspring with features that are different from those of either parent is called recombination.
Chromosome arms may touch during the alignment and momentarily merge, leading to a crossover. Recombination and the transfer of genetic material between the maternal and paternal chromosomes occur as a result of crossovers. As a result, a child's gene combinations may differ from those of their parents.
As a result of genetic recombinations, the species integrity—an essential structure responsible for the preservation and improvement of ecological stability of animals in developing lineages—is continuously homogenized within the species.

In anticipation of cell division cells must first
A grow large enough
B replicate their DNA
C replicate their organelles
D all of the above
Answer:
D
Explanation:
Cells must replicate their DNA and organelles to split evenly between the two new cells, and to be able to have the cells be equal size to other cells, they must grow large as well.
D. all of the above
Before a cell divides, the strands of DNA in the nucleus must be copied, checked for errors and then packaged into neat finger-like structures. The cell division stages encompass a complicated process that involves many changes inside the cell.Cells must replicate their DNA and organelles to split evenly between the two new cells, and to be able to have the cells be equal size to other cells, they must grow large as well.Since, all options are correct. Therefore, option D is correct.

Ocean Acidification Evidence
Ocean Warming Evidence
:: expansion of ocean volume
:: difficult for some species to make shells
:: larger concentration carbonic acid
:: melting of glaciers and ice caps
growing difficulty in absorbing carbon dioxide
:: organisms more prone to illness
Answer:Ocean Acidification Evidence: Difficult for some species to make shells , larger concentration, organisms prone to illness . Ocean warming evidence: Melting of glaciers, expansion of ocean volume, growing difficulty in absorbing
Explanation:
Ocean Acidification Evidence includes difficult for some species to make shells , larger concentration, organisms prone to illness. Ocean warming evidence encompasses melting of glaciers, expansion of ocean volume, growing difficulty in absorbing.
What is ocean acidification?The massive amount of carbon dioxide absorbed by the ocean dissolves as carbonic acid in seawater.
This is known as ocean acidification, and it is literally causing a sea change that is threatening the basic chemical balance of ocean and coastal waters from pole to pole.
As greenhouse gases trap more solar energy, the oceans absorb more heat, resulting in higher sea surface temperatures and rising sea level.
Ocean acidification is the decrease in pH of ocean water caused by CO2 dissolution in water.
Ocean warming, on the other hand, is the long-term gradual increase in the average temperature of the Earth's atmosphere. Ocean acidification and global warming are both negative consequences of human activity.
Acidification of the Oceans Evidence: It is difficult for some species to make shells, there is a higher concentration, and organisms are prone to illness.
Melting glaciers, increased ocean volume, and increasing difficulty absorbing are all signs of ocean warming.
Thus, this is the match for the given scenario.

Answer: When the virus is inside the cell, it will open up so that its DNA and RNA will come out and go straight to the nucleus. They will enter a molecule, which is like a factory, and make copies of the virus. These copies will come out of the nucleus to be assembled and receive protein, which protects their DNA and RNA.

The adaptive value of allele b decreased.
The adaptive value of allele b increased.
The population of this insect species increased.
The population of this insect species decreased.
Answer:
The correct answer is - The adaptive value of allele b increased.
Explanation:
In this given population of insects, there is an increase in the number of insects in the given time of five years as initially there were 2800 insects and after five years there are 4000 insects, however, it is not the most probable explanation for the change in the phenotype as phenotype change does not depend on the size of population alone.
In this case, there is a drastic increase in the number of the recessive allele in last five years that suggests that adaptive value is increased of recessive allele due to some environmental change or mutation in the gene.

Rectangle ABCD went through a transformation and is now rectangle A'B'C'D'. Explain two different ways how rectangle ABCD becomes rectangle A'B'C'D'.
Answer:
(c)
Explanation:
Given
See attachment for rectangles ABCD and A'B'C'D
Required
Determine two possible ways of transformation
From the attachment, we have:
ABCD coordinates:
[tex]A = (-6,5)[/tex]
[tex]B = (-1,5)[/tex]
[tex]C = (-1,1)[/tex]
[tex]D = (-6,1)[/tex]
A'B'C'D' coordinates:
[tex]A' = (5,-1)[/tex]
[tex]B' = (5,-6)[/tex]
[tex]C' = (1,-6)[/tex]
[tex]D' = (1,-1)[/tex]
The first transformation is a rotation of ABCD by 90 degrees using the rule:
(x,y) => (y,-x)
So, we have:
[tex]A = (-6,5)[/tex] ===> [tex](5,6)[/tex]
[tex]B = (-1,5)[/tex] ===> [tex](5,1)[/tex]
[tex]C = (-1,1)[/tex] ===> [tex](1,1)[/tex]
[tex]D = (-6,1)[/tex] ===> [tex](1,6)[/tex]
Next, is to translate 7 units down using the rule
(x,y) => (x,y-7)
So, we have:
[tex](5,6)[/tex] ==> [tex](5,6-7)[/tex]
[tex](5,1)[/tex] ==> [tex](5,1-7)[/tex]
[tex](1,1)[/tex] ==> [tex](1,1-7)[/tex]
[tex](1,6)[/tex] ==> [tex](1,6-7)[/tex]
This gives
[tex]A' = (5,-1)[/tex]
[tex]B' = (5,-6)[/tex]
[tex]C' = (1,-6)[/tex]
[tex]D' = (1,-1)[/tex]
Option (c) is correct

What are the different types of granulocytes? Select all that apply.
basophils
T-cells
eosinophils
monocytes
neutrophils
There are four types of granulocyte;
Explanation:
basophils, eosinophils, neutrophils and mast cells.
The different types of granulocytes are: basophils (option A), eosinophils (option C), and neutrophils (option E). Granulocytes are a type of white blood cell that are characterized by the presence of granules in their cytoplasm.
What are granulocytes?The three types of granulocytes are basophils, eosinophils, and neutrophils such as basophils are the least common type of granulocyte. They are characterized by their large, dark-staining granules and play a role in allergic reactions and inflammation. Basophils release histamine, which causes blood vessels to dilate and become more permeable. Eosinophils are the second-least common type of granulocyte, and neutrophils are the most common type of granulocyte. They are characterized by their small, pale-staining granules.
Hence, the different types of granulocytes are: basophils (option A), eosinophils (option C), and neutrophils (option E).

Answer:
Basically, the peppered moths had to adapt due to the color of their surroundings changing. This was influenced by an abiotic factor because the trees changed color due to the soot and ash produced during the industrial revolution. This would change the color of the moths because if they were lighter living in a habitat with dark surroundings or vise versa, they would be more likely to be eaten/killed by predators and wouldn't be able to survive and reproduce to keep the species alive.
