When considering an RBC histogram, what can cause an elevation in the left side of the curve?
stepladder [879]

Answer:

Low mean corpuscular value can shift the curve to the left side.

Explanation:

RBC histogram may be defined as the process of plotting the number of blood cells on Y- axis and their relative size on X- axis. Modern automated haematology is used for the construction of RBC histogram.

The cell population of RBCs is similar in size but not equal to the size of RBC the curve can shift to either direction. The low MCV (mean corpuscular value) value can shift the the curve to the left side while considering an RBC histogram.

Which relationship is an example of commensalim?
azamat
One of the most poplar examples of commensalism is the relationship between cattle egrets and livestock.

Wood deposits recovered from an archaeological site contain 36% of the C-14 they originally contained. How long ago did the tree
Veseljchak [2.6K]

Answer: It was obtained 8515 years ago

Explanation:

Expression for rate law for first order kinetics is given by:

t=\frac{2.303}{k}\log\frac{a}{a-x}

where,

k = rate constant

t = age of sample

a = let initial amount of the reactant

a - x = amount left after decay process  

a) to find the rate constant:

Half life is the amount of time taken by a radioactive material to decay to half of its original value.

t_{\frac{1}{2}}=\frac{0.693}{k}

k=\frac{0.693}{5760}=0.00012years^{-1}

b) for completion of 36% of reaction

t=\frac{2.303}{k}\log\frac{100}{36}

t=\frac{2.303}{0.00012}\log\frac{100}{36}

t = 8515 years

The time was 8515 years.

Compare and contrast genetic engineering to the process of natural selection select all statements that are are
alisha [4.7K]

Genetic engineering is due to the human selection of desired phenotypes, whereas natural selection is a slow process of differential survival and reproduction.

<h3>What does natural selection mean?</h3>

According to the evolution theory, natural selection is a slow process of differential survival of the fittest organisms in a given environment.

Conversely, genetic engineering refers to the molecular biology techniques used in the laboratory to produce organisms expressing desired phenotypes.

In conclusion, genetic engineering is based on human molecular biology techniques, whereas natural selection refers to differential survival and reproduction in nature.
