The lost carbons are released as CO2.

Krebs Cycle- The Krebs cycle, sometimes called the TCA cycle or the citric acid cycle, is a series of chemical processes that take place in the mitochondria and are essential for the aerobic respiration that provides energy to nearly all living things. It consumes oxygen and produces carbon dioxide and water as waste. ATP is created here from ADP.

Mitochondria- The majority of the chemical energy required to drive a cell's metabolic operations is produced by mitochondria, which are membrane-bound cell organelles (mitochondrion, singular). Adenosine triphosphate, a tiny molecule, serves as a storage container for the chemical energy generated by the mitochondria (ATP).

Why is crossing over an essential step in meiosis
marshall27 [118]

Crossing over is essential for the normal segregation of chromosomes during meiosis. Crossing over also accounts for genetic variation, because due to the swapping of genetic material during crossing over, the chromatids held together by the centromere are no longer identical.

Imagine that you take a journey through time, starting in the age of the dinosaurs. You see plants and animals as they turn into
VLD [36.1K]

Answer:

You take any of the "signs of change in populations of organisms and their environments". For imagine, Australopithecus (early man) turning to Homo sapiens. In that way they could tell that you took this journey.

aksik [14]

Answer:

For sample A, A=17.7 %, T=17.7 %, G=32.30%, C=32.30%

For sample B, A= 28.9%, T=28.9%, G= 21.10%, C= 21.10%

Explanation:

The composition of nitrogenous bases in DNA is calculated using the suggestions proposed by the results of the experiment performed by Erwin Chargaff.

He found that in a DNA sample the composition of purine to pyrimidine is 1:1. This indicates that the amount of purine equals pyrimidine. This can be presented as purines + pyrimidines= 100. Also, adenine binds thymine and cytosine binds guanine.

In the given question,  

<u>For sample A </u>

A= 17.7 %, Therefore, thymine will be = 17.7 %,

A+T= 35.40%

Now, G+C=100- 35.40%

G+C= 64.60%

content of G= 64.60/2= 32.30%

content of C= 32.30%

<u>For sample B </u>

T=28.9%, A will be= 28.9%

A+T= 57.80%

G+C=100-57.80%

G+C= 42.20%

Thus content of G will be= 42.20/2=21.10

content of C= 21.10%

Thus,  

For sample A, A=17.7 %, T=17.7 %, G=32.30%, C=32.30%

For sample B, A= 28.9%, T=28.9%, G= 21.10%, C= 21.10%

Describe how each of these 4 processes can affect salinity. Are they increasing or decreasing the salinity?
Charra [1.4K]

Iceberg: The formation of icebergs increases salinity because it is taking liquid water out of the ocean without taking the salt.

Sea Ice: Same as icebergs, this increases salinity because it removes liquid water.

Runoff: This decreases salinity because it is introducing fresh water into the ocean, reducing the salt to water ratio.

Evaporation: This would increase salinity because it is removing liquid water from the ocean, increasing the salt to water ratio.

Hope this helps!
