The cell cycle of yeast cells grown in the nutrient-poor environment is approximately what percent of the cell cycle of yeast cells grown in the nutrient-rich environment.

Answers

Answer: 168

Explanation:

The cell cycle of yeast cells grown in the nutrient-poor environment is approximately 168 % of the cell cycle of yeast cells grown in the nutrient-rich environment. Hence option 1 is correct.

What is cell cycle?

Cell cycle is defined as the cascade of cellular activities that lead to cell division into two daughter cells. The primary purpose of the cell cycle is to accurately divide the enormous amount of DNA found in the chromosomes into two daughter cells that are genetically identical. A cell spends the majority of its time in what is known as interphase, where it develops, duplicates its chromosomes, and gets ready to divide.

The interphase and M-phase are the two phases that make up the cell cycle. About 90% of the cycle is made up of interphase, during which the cell develops and copies its chromosomes in order to divide. Undifferentiated ESCs have a G1 and S cell cycle percentage of 15-20% and 60–70%, respectively, however as the ESCs differentiate, this ratio changes.

Thus, the cell cycle of yeast cells grown in the nutrient-poor environment is approximately 168 % of the cell cycle of yeast cells grown in the nutrient-rich environment. Hence option 1 is correct.

Some salmon have been genetically modified to grow bigger and faster than wild salmon. They are grown in fish-farming facilities. These genetically modified fish should not be introduced into a natural habitat because
A)
the salmon would recycle nutrients at a rapid rate

B)
their rapid growth rate could cause them to outcompete native salmon

C)
they would not have enough oxygen for survival

D)
they would reproduce asexually once they were released

Answers

Answer:

B

Explanation:

Their growth rate would cause them to grow much larger than the native salmon meaning they require more habitat space and sustenance to live. This would drive out the native salmon as they wrestle for food and space.

Hurricanes tend to disperse after making landfall because the land is much hotter than the ocean water.

Answers

Answer: False

Explanation:

For a Hurricane to keep going it needs to have hot air constantly going up and cold air coming down. When it gets to land, it loses access to the heat and moisture of the sea which is greater than on land. This forces it to weaken and to eventually dissipate.

Therefore, hurricanes disperse after making landfall because land is not as hot as the ocean water.

How do convection currents work?

Answers

Answer:

Convection currents form because a heated fluid expands, becoming less dense. ... As it rises, it pulls cooler fluid down to replace it. This fluid in turn is heated, rises and pulls down more cool fluid. This cycle establishes a circular current that stops only when heat is evenly distributed throughout the fluid.

Explanation:

Convention currents work by forming a heated fluid expanding making it less dense.  As the current rises, it pulls cooler fluid down to replace it.

If a muscle contracts isometrically for a long period of time, an EMG (which records the electrical activity in the muscle) recording shows that as the amplitude (frequency of action potential) increases, the contractile force slowly decreases. What is the explanation for this?

Answers

Answer:

During the course of a continuous isometric contraction of given strength, the electrical activity progressively increases. This is due to recruitment of motor units taking place to compensate the decrease in force of contraction occurring in the fatigued muscle fibres.

Continue building the strand of mRNA until you have used all of the RNA nucleotides. What is the nucleotide sequence of the mRNA strand you built?

Answers

Answer:

This question is incomplete

Explanation:

However, mRNA can be built from a DNA sequence; i.e a DNA strand is used as a template for the production of an mRNA sequence. This process occurs during transcription. While the four nitrogenous bases in a DNA molecule are adenine, thymine, guanine and cytosine, in RNA the thymine is absent and replaced with uracil. While producing the mRNA strand, Uracil will be complementary to adenine, adenine will be complementary to thymine, guanine will be complementary to cytosine and cytosine will be complementary to guanine. This can be seen in the illustration below:

DNA sequence:    T--G--G--C--A--G--C--T--A--C--C--G

mRNA sequence:     A--C--C--G--U--C--G--A--U--G--G--C

Thus, while building a mRNA nucleotide sequence, the procedure above can be followed
