Suppose members of a true-breeding strain of salamanders with yellow stripes are crossed with a true-breeding strain with red st

ripes. Red and yellow are two alleles of the same gene. The resulting offspring have both yellow stripes and red stripes. Which dominance pattern is most likely?

Answer:

Co-dominance pattern

Explanation:

<em>Co-dominance is a phenomenon in which the two alleles of a gene exert equal effects on each other. That is neither allele of a gene is has the ability to suppress the expression of the other.</em>

On the other hand, the alternate version of a gene represented by alleles are both expressed phenotypically in individuals carrying a co-dominant gene.

<u>Apart from the illustration shown in the question, a good example of co-dominance can be observed in the human ABO blood system in which both allele A and B are expressed in individuals with AB blood group.</u>

6. Adolescent females often require additional amounts of iron in their diet. Explain why.
Oxana [17]
Our blood contains a large proportion of the iron in our bodies. Because women lose blood during a period, they also lose iron. This means that they need more iron in their diet to counteract this.

Question 1 of 10
Sati [7]

Answer: Option A) Parathyroid glands

Explanation:

The Parathyroid gland located in the neck region helps in the secretion of an hormone called Parathormone.

This hormone helps to raise the levels of calcium ions in the body, by preventing the loss of calcium ions through urine, and also preventing excess deposit of calcium ions in the bone, thus regulating bone density.

If 1/8 remains after 21 years, what is the half-life?
vagabundo [1.1K]

Half life formula

The number of unstable nuclei remaining after time t can be determined according to this equation:

N(t) = N(0) * 0.5^(t/T)

where:

N(t) is the remaining quantity of a substance after time t has elapsed.

N(0) is the initial quantity of this substance.

T is the half-life.

It is also possible to determine the remaining quantity of a substance using a few other parameters:

N(t) = N(0) * e^(-t/τ)

N(t) = N(0) * e^(-λt)

τ is the mean lifetime - the average amount of time a nucleus remains intact.

λ is the decay constant (rate of decay).

All three of the parameters characterizing a substance's radioactivity are related in the following way:

T = ln(2)/λ = ln(2)*τ

How to calculate the half life

Determine the initial amount of a substance. For example, N(0) = 2.5 kg.

Determine the final amount of a substance - for instance, N(t) = 2.1 kg.

Measure how long it took for that amount of material to decay. In our experiment, we observed that it took 5 minutes.

Input these values into our half life calculator. It will compute a result for you instantaneously - in this case, the half life is equal to 19.88 minutes.

If you are not certain that our calculator returned the correct result, you can always check it using the half life formula.
