Answer:

If the emission of greenhouse gases were stopped, global warming would still happen due to the gases that are already in the atmosphere and the constant deforestation.

Explanation:

Greenhouse gases are the biggest creators of global warming. This is because these gases cause holes in the ozone layer, which protects the planet from the sun's rays. These holes cause the sun's rays to reach the earth's surface with greater intensity, promoting global warming.

Trees are able to absorb these gases, decreasing their concentration in the atmosphere and preventing them from degrading the ozone layer. However, the constant deforestation has reduced the number of plants and the remaining amount on the planet cannot cope with the constant emission of these gases. In this case, even if the emissions of greenhouse gases were ended, the amount of these gases in the atmosphere would still be very large. Plants were slow to absorb all these gases, which would not prevent global warming from happening.

The directions for generating MHC comes from the option c. inherited DNA. hence, the option c is correct.

The full form is a major histocompatibility complex. It is the genes group that have the proteins code that should be founded on the cell surface which helped the immune system, that recorded in the foreign substance.

So at the time of directing, it produced MHC that came from inherited DNA.

hence, the option c is correct.

The answer is "Sympatric speciation due to disruptive selection"

Explanation:

Disruptive selection is a certain type of natural choice, that aggressively favors all ends of the spectrum in a moderate community. Disruptive selection is often deduced by a phyletic prepared to change to contribute to speciation. These two species happened due to various habitats associated with extreme speciation due to various confusing choices.

Answer:

Bacteria are neither animals nor plants.... Because bacteria are prokaryotic, they do not have a nucleus and no membrane-bound organelles. In contrast, plants and animals are made up of eukaryotic cells, which means they have a nucleus and membrane-bound organelles like mitochondria or golgi apparatus.

Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust.

Sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification. Erosion and weathering include the effects of wind and rain, which slowly break down large rocks into smaller ones.

Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.

Explanation:

Answer:

1. Igneous rocks form when magma molten rocks cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. All magma develops underground, in the lower crust or upper mantle, because of the intense heat there.

2. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.

3. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification. Erosion and weathering include the effects of wind and rain, which slowly break down large rocks into smaller ones.

Answer:

In cellular respiration, complex molecules containing carbon react with oxygen to produce carbon dioxide and other materials. Within individual organisms, food moves through a series of chemical reactions in which it is broken down and rearranged to form new molecules to support growth or to release energy.

Explanation:

The glucose and oxygen atoms are rearranged into carbon dioxide and water molecules during aerobic respiration. Being an exothermic chemical reaction, this process releases energy as it goes along.

A chemical reaction that converts carbohydrates into energy using oxygen (sugars). also known as oxidative metabolism, aerobic metabolism, and cell respiration.

During aerobic cellular respiration, glucose and oxygen combine to create ATP, which the cell can utilise.

As byproducts, carbon dioxide and water are produced. The general equation for aerobic cellular respiration is: ATP is produced when glucose and oxygen combine in cellular respiration.

During aerobic respiration, glucose and oxygen atoms are rearranged into carbon dioxide and water molecules. As it proceeds, this process releases energy since it is an exothermic chemical reaction.

Thus, molecules of food rearrange when they react with oxygen in the cells of your body.

Answer:

5.) The possible genotypes should be: RR RB BB ( if the could for the same proteins)

6.) Frequency of R: 0.5

7.)Frequency of R: 0.5

8.)Frequency of R: 0.375

Explanation:

5.) If R and B code for the different forms of the same protein then they are only a few possible out comes

6.) First calculate the total alleles in population

allele R= 40

Allele B=40

total allele = R+B= 40+40

=80

Now to find allele R frequency is:

(Total R alleles) / (Total allele in pop)

40/80=

0.5

7.)Calculate the total alleles

Alleles from for R

RR= 10

R=10x 2= 20

Multiply the value by 2 because there are 2 R alleles present in

RB=20

R=20

Number doesn't change there is only 1 R allele

Total R=20+20

=40

Alleles For B

BB=10

B=10×2

=20

Same thing here, two B alleles together so multiple by 2

RB=20

B=20

Total B= 20+20

=40

Total alleles in pop add

40+40

=80

Frequency of R

Total of R/Total Alleles

=40/80

=0.5

8.)Repeat the same thing in 7 but use different numbers

RR=10

R=10x2

=20

RB=10

R=10

Total R= 20+10

=30
