Propose an experiment that would test if the RNA component of telomerase serves as a template to extend telomeres. A cell free s

IceJOKER [234]

Answer:

To study the importance of the RNA telomer element, we can evaluate it by generating an in vitro state where all the purified components are included, organizing two groups, one of them will have an RNAase and the other will not, if it is observed that the telomeres extend to the component of the RNA, in the set where there is no RNAase, longer telomeres could be observed, if there were no influence of the RNA, the length in both groups would be the same

Newsweek in 1989 reported that 60% of young children have blood lead levels that could impair their neurological development. As

Kamila [148]

Answer:

The answer is 83.38%.

Explanation:

The probability of young children having blood levels that impair their neurological development is given as 60% in the question. To find the probability of at least 5 children out of 10 in a sample having said blood levels, we need to use the binomial probability.

n represents the total number of children in the sample so n = 10 and p is the probability of the children having blood levels causing the problem which is 60% so p = 0.6.

We want the probability of it being observed for 5 or more children and that is $P(x\geq 5)$ . If we subtract the $P( x\leq 4)$ from 1, which is the probability of not observing the condition in 5 or more children, we will have the $P(x\geq 5)$ .

$1 - P(x\leq 4) = 1 - pbinom(4, 10, 0.6)$ which are the probability range in the function, the sample size and the probability of observing the condition respectively.

The result is 1 - 0.1662 = 0.8338 which means that the probability that is asked is 83.38%.

I hope this answer helps.

Suppose that a dominant allele (P) codes for a polka-dot tail and a recessive allele (p) codes for a solid colored tail. If two

Oduvanchick [21]

Option A is correct. After making a punnet square, we can see that the genotypic ratio would be 1:2:1, being 25% dominant, 25% recessive and 50% heterozygous. However, we are asked for the phenotypic trait percentage. The phenotypic ration is 3:1, with 75% polka dotted tail (dominant gene active) and 25% solid tail (recessive gene active).

Pls thanks + branliest :P
