Fossil Fuels are one form of pollution. It can affect the balance by making Carbon more dominant than Oxygen. If the fossil fuels continue to increase. Oxygen will decrease and we will all die because of no oxygen to breathe in.

Suppose virus A has a viral genome of 19,000 bp, and 10,000,000,000 viruses are replicated in an infected individual in a single

Kitty [74]

Answer:

1 day.

Explanation:

From the given information:

The rate of mutation induced by RNA polymerase is:

$\implies \dfrac{1}{10000}= 0.0001$

Since the genome comprise of 19000 bp;

To complete a single replication, the viral cycle induce: $= \dfrac{19000}{1000}$

$= 1.9 \ mutation \\ \\ \simeq 2 \ mutation$

However, in a single day; 10,000,000,000 viruses are reported to be replicated.

Hence, if a virus has 2 mutations; Then 10,000,000,000 virus will have:

$= \dfrac{10,000,000,000}{2} \\ \\ = \text{5000000000 \ mutations \ in \ a \ half \ day which is half} \\ \\ \text{ the given no of the replicated virus}$

SO, to round this up to whole number, it will take 1 day (s) to overcome the therapy.

The large size of the daughter oocyte after meiosis II results from the uneven distribution of the cytoplasm, which allows the z

Naddika [18.5K]

Answer:

True

Explanation:

Oogenesis includes the formation of one egg cell from a single oocyte or egg mother cell. The diploid primary oocytes in the ovaries enter into the first meiotic division and form a haploid secondary oocyte and a haploid first polar body. After fertilization, the secondary oocytes complete the meiosis-II and forms one large ovum and a second polar body. The ovum formed by meiosis-II is much larger than the second polar body due to the unequal distribution of cytoplasm during meiosis-II. This imparts enough amount of cytoplasm in the zygote to support the mitosis without any cell growth.

liraira [26]

I would say (A) because it allows the bacteria (bacteria X) to be exposed to the control condition and the experimental condition so that a cause-effect relationship can be established. Here, the control condition would be the darkened area and the experimental condition would be the lightened area.

Sort the statements based on whether they describe DNA replication in eukaryotes or prokaryotes. Replication takes place in the

Ilya [14]

In eukaryotes, replication takes place in the nucleus as prokaryotes do not have a true nucleus and replication takes place in the cytoplasm. The nucleus of the eukaryotes is the location where genetic material (DNA) is found; in prokaryotes, the genetic material is condensed in the cytoplasm called the nucleoid. There are multiple replication forks or multiple origins of replication in eukaryotes in contrast to prokaryotes which only has one origin of replication. Lastly, replication in eukaryotes occurs at multiple points along the chromosome; in contrast with prokaryotes where it occurs at just one point on the chromosome.
