Answer:
Meiosis consists of one round of DNA replication and two rounds of chromosome segregation.
Explanation:
DNA replicates twice during meiosis. Meiosis consists of one round of DNA replication and two rounds of chromosome segregation. Therefore, this statement in false.
What do you mean by meiosis?Meiosis is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, such as sperm or egg cells. It involves two rounds of division that ultimately result in four cells with only one copy of each chromosome.
Meiosis is a type of cell division in sexually reproducing organisms that reduces the number of chromosomes in gametes (the sex cells, or egg and sperm). In humans, body (or somatic) cells are diploid.
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.

How are humans changing the carbon cycle?
Humans are planting more trees to add more oxygen to to the carbon cycle.
Humans are adding carbon to the Earth by over-farming,
Humans are burning carbon and putting it into the atmosphere.
Humans change the carbon cycle by burning carbon and putting it into the atmosphere. Thus, the correct option for this question is C.
What is the Carbon cycle?The carbon cycle may be defined as a type of biogeochemical cycle through which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. This cycle governs the exchange of carbon and its derivatives among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.
The activity of Plants in the carbon cycle is determined by the fact that they breathe carbon dioxide. Humans are often cutting them down and the carbon dioxide stays in the air.
Apart from this, the burning and combustion of fossil fuels, trees, and chemicals increase the level of carbon in the atmosphere. Due to these human actions, the carbon cycle may be changing gradually.
Therefore, the correct option for this question is C.

why is vacuole in plant cell larger than a vacuole in an animal cell?
Answer:
The plant has the largest vacuole than animal cells because in plant cells the larger central vacuole performs two functions, one is to store water and the other is to help the plant remain upright. In animal cells, vacuoles are smaller but more in number because they do not require vacuole for rigidity or pressure.

In determining probabilities all you need to do is count and then divide by the number of results.
What is punnett square?A Punnett Square is a useful tool for forecasting the changes and probabilities that can result from cross-breeding. This includes foreseeing the mating of different species, including humans and animals.
It is asking the chances of having green seeds and that's the recessive allele. For recessive traits to be expressed, there can't be a dominant trait next to it because the dominant trait will always be expressed. So the expected result should be yy (two lowercase) if you want the recessive trait to be expressed.
In the Punnett square of the second generation, there is 1 out of 4 yy genotype. So then divide 1 by 4 and multiply it by 100% to get the probability in percent. So in short, the answer is 25%.

The revisions to the model that would be most useful for the researcher to include is the replacement of thymine (T) with uracil (U) in the DNA molecule.
What do you mean by Transcription?Transcription may be defined as a process by which DNA is converted into mRNA in the nucleus of the cell.
In RNA, thymine is replaced by Uracil because during the elongation process, the presence of adenine in the DNA strand message the RNA polymerase to attach uracil in the complementary area of the elongated RNA strand.
Apart from this, Uracil requires less energy in the production as compared to thymine.
Therefore, the revisions to the model that would be most useful for the researcher to include is the replacement of thymine (T) with uracil (U) in the DNA molecule.

how certain structures affect the function of reduced collision impact? PLEASE ITS DUE IN 30 MINS I NEED AN ANSWER
Answer:
When the size of a fixed mass of a solid reactant decreases, the rate of reaction increases.
This can be explained using the collision theory, as below:
When the size of a fixed mass of a solid reactant becomes smaller, the total surface area exposed to collision with the particles of the other reactants increases As a result, the frequency of collision among the reacting particles at the surface of the solid reactant increases. This causes the frequency of effective collision to increase. Hence, the rate of reaction increases.
