Answer:

Cellular differentiation is a process that exists in physiological, pathological and embryologic processes. In these processes a cell changes from one cell type to another. This process is related with the fact that somatic cells has the potential to grow and develop a multicellular organism, the development of an adult organism from a zygote is the result of cell division and differentiation

A scientist is studying the population of a particular species of beetle in an ecosystem. The beetles currently have an estimate

Snowcat [4.5K]

Answer/Explanation:

Given an estimated beetle population of 11,500, of which it is estimated to increase approximately by 5% each year, we can calculate the estimated population for each year as follows:

Year Calculation Est. Population

1st yr (current yr) 11,500

2nd yr 11,500*105% 12,075

3rd yr 12,075*105% 12,679

4th yr 12,679*105% 13,313

5th yr 13,313*105% 13,979

6th yr 13,979*105% 14,678

The above is how the table would like showing the estimated population for each year.

a man with blood group A marries a woman with blood group O and their daughter has blood group O. Is this information enough to

Nonamiya [84]

This information is not enough to tell which of the traits-blood group A or O is dominant.
It is known that blood groups A and B are codominant, which means both will express if found together in a heterozygote. However, blood group O is recessive. But from this information, you can conclude that blood group O is dominant. Why is that so?
Let's imagine that father's genotype is AA and mothers' genotype OO and cross them:
Parents: AA x OO
Offspring: AO AO AO AO
Since we have information that daughter has blood group O, we can conclude that O is dominant over A and mask it. This is not true! In this case, the daughter will have blood group A.

Mother's genotype surely is OO (because O allele is recessive, so to express a recessive trait both alleles must be recessive). But, the father cannot be AA, because it must give O allele to the daughter so she can have genotype OO and blood group O. So, the father's genotype is AO. Let's take a look at that crossing:
Parents: AO x OO
Offspring: AO AO OO OO
Thus, in this case, daughter can have genotype OO and blood group O.

Each of the following statements concerning hair is true except

Levart [38]

Answer: A. scalp hairs grow constantly throughout life.

Explanation:

Hair is a squamous keratinized epithelium which is consist of multi-layered flat cells. Hair are made up of protein called "keratin".

The statement "scalp hairs grow constantly throughout life" is false because at a particular age or due to several factors scalp hairs stop growing.

Scalp hair growth rate depends on three main factors including sex (female hair grows faster than male), age (hair growth slows with age), and ethnicity (Asian hair grows slower than Caucasian hair).

Scalp hair growth stops because of follicle devitalization when the hair length become two or three feet.

Hence, the correct answer is A. "scalp hairs grow constantly throughout life".
