The correct answer is -
Conversion of forest to cropland or pasture decreases the rate at which carbon is taken up by plants.
Cut trees are often burned, and this releases carbon into the atmosphere.
Explanation:
Deforestation is the manual removal of the forest and trees permanently to make the land available for places other than forests such as agricultural land, road or cities, and industries. There are many negative impacts of deforestation on the environment and ecology such as reduces biodiversity , soil erosion , a higher chance of flooding , educes soil fertility , global warming, and many more.
Global warming can be influenced by deforestation as if the forests are removed to create cropland the uptake of carbon dioxide will be very less in comparison to the forests as trees use carbon uptake at a higher rate. Many times deforestation also results in burning the trees and log of trees which contribute to the release of more carbon dioxide in the atmosphere. So deforestation means more CO2 in the atmosphere which leads to global warming.

The recombination frequency between linked genes A and B is 40%, between B and C is 20%, between C and D is 10%, between C and A is 20%, and between D and B is 10%. What is the sequence of the genes on the chromosome?
Answer:
ACDB (or BDCA)
Explanation:
The linked genes A and B have a greater frequency of recombination (40%) and therefore they are found furthest away on the chromosome. Conversely, the smaller distance is between D and B, which exhibit a lower frequency of recombination (10%), while C is localized at the same physical distance of both A and B (20%), so the physical map is ACDB.

Oxygen has 6 valence electrons. How many electrons does an atom of oxygen need to become stable?
two
four
six
eight
Answer:
2 electrons
Explanation:
According to the octet rule, atoms must bond to each other, sharing electrons among themselves in an attempt to complete their valence shell (last layer of the electrosphere). In other words, an atom becomes stable when it has 8 electrons in its valence shell.
Oxygen atoms have six electrons in their valence shell, so to achieve the stability suggested by the octet rule (eight electrons), these atoms share two electrons, forming one oxygen gas (O₂) molecule.

A. two

What will be the end result of the process shown in the model?
A. Two identical daughter cells will be produced.
B. Crossing over will result in new genetic material.
C. Chromatids will have just moved toward opposite poles.
D. One much larger cell will be produced through nuclear fusion.
Answer:
i think its b i could be wrong
Explanation:
The correct model shown is Crossing over will result in new genetic material.
What is crossing over?
When it comes to genetics and genomics, the term "crossing over" describes the DNA exchange that takes place between paired homologous chromosomes (one from each parent) during the development of egg and sperm cells.
This process leads to novel allele combinations in the gametes (egg or sperm) produced, ensuring genomic variety in any offspring born.
When chromosomes of the same type are paired together during meiosis, a biological event called crossing over takes place. Parts of the chromosome can be exchanged when two chromosomes, one from the mother and one from the father.
Therefore, The correct model shown is Crossing over will result in new genetic material.

Explanation: We know for certain the son is NOT ww because the son has the dominant trait for the widow's peak. Both the parents are Ww because their daughter lacks a widow's peak, which means they both must carry the recessive gene. If we conduct a Punnett Square with the parents genotypes which are both Ww, the son has a 25% chance to be WW, and a 50% to be Ww and a 25% chance to be ww (which he is not since he has a widow peak!). The son could be WW or Ww. In order to find out which genotype the son has, we'd have to look as his offspring!

F. Cells protect their DNA by enveloping it in a nucleus.
G. Cells do not transcribe all of their genes all of the time.
H. Each cell has an exact copy of all DNA.
3. Each tRNA has a specific amino acid that it carries.
Answer:
Explanation:
hi
Regulation of gene expression involves process by which a cell determines which genes, among the numerous genes in its genetic make-up, are "switched on" (expressed).
The option that demonstrate that gene expression is regulated is that Cells do not transcribe all of their genes all of the time.
In eukaryotes, regulation of gene expression can take place at various points. This might include post transcriptional and post-translational modifications. This mechanism ensures to control some various processes which include:

g When an oxygen molecule diffuses from the air in the lung into the plasma in a capillary in the lung, how many times does it have to diffuse through a plasma membrane before reaching the plasma
Answer:
The answer is 2.
Explanation:
When oxygen gets into the lungs, it first needs to diffuse through the alveoli and into the blood. Then through the veins and capillaries, it diffuses into all the calls in the body. It does so quite easily because it is a nonpolar and a very small molecule with a low concentration inside the cell. This gives it the ability to diffuse easily through the cell membrane.
So the number of times that oxygen has to diffuse through a plasma membrane is two.

When a hawk eats a mouse and then uses the energy from the mouse to fly,
the hawk's body converts to what
Answer:
It would be Chemical to mechanical
Explanation:
Because food is a chemical source and the hawk flying is a mechanical source.
When a hawk eats a mouse and then uses the energy from the mouse to fly in this case chemical energy is converted to mechanical energy.
What is food chain?Food chain is the sequence of flow of energy in which all the levels get proper food supply and it is the food web which starts from producer and ending at top such as predator species, decomposer and detritivores.
In food chain plants play the role of producers as they are autotrophs and they prepare their own food in the presence of sunlight and all other organisms depend upon plant for food so they are known as producers in the food chain.
The main role of food chain is to understand the importance of each organisms and how they are depend on each other as well as to understand the role of food chain in maintaining ecological balance.
Therefore, When a hawk eats a mouse and then uses the energy from the mouse to fly in this case chemical energy is converted to mechanical energy.
