Answer:
Approximately 28 minutes.
Explanation:
Given:
Length of a duplex molecule of DNA = 10 mb
= 10 * 10^6 bases
So, it means each DNA has = 5 * 10^6 base pair
rate of DNA synthesis = 1500 nucleotide pairs per sec.
location of replication = at the middle which is 5 * 10^6/2
= At 2.5 * 10^6
solution:
As we know replication of DNA is a bidirectional process so it will synthesize in both directions and the rate is given is 1500 nucleotide per sec so the time required to replicate 2.5 * 10^6 in both directions will be from the formula
time = distane/rate
= 2.5 * 10^6/1500
= 1666.66 seconds
or, 28 minutes aprrox (27.77)
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.
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
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.

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?
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

CO₂ is a gas that composes the atmosphere, but its increase contributes to the greenhouse effect. C)CO₂ has increased as a result of increased human activities.
What is CO₂, and how does it affect the greenhouse effect?Carbon dioxide (CO₂) is a gas that, among other gases, composes the atmosphere, mainly the troposphere, which is closest to the Earth.
The balance of this gas in nature is very complex and involves interactions between the atmosphere, the plants, and the oceans.
CO₂ is essential for plants to photosynthesize. Photosynthesis transforms CO₂ into organic compounds and releases oxygen as final products together with carbohydrates.
This gas is not nocive at concentrations between 300 and 500 ppm. However, the current increase in CO₂ is a responsible component of the greenhouse effect involved in global warming and climate change. The rise in CO₂ is possibly the best documented.
The atmospheric increase of CO₂ follows a natural fluctuation trend that has been happening throughout the whole of Earth's history.
It has been proven that the current rise in CO₂ concentration overlaps the expected variation and that the reached levels at the moment exceed the highest past registered levels. This substantial increase must be related to human activities, such as forest destruction, industry, and fossil fuel uses, among many others.
The correct option is C. Carbon dioxide has increased as a result of increased human activities.
