Answer:
The question lacks options, the options are:
A). the body cell has 2n; the sex cell has 1n.
B). the body cell has 26; the sex cell has two.
C). the body cell has 1n; the sex cell has 2n.
D). the body cell has 24; the sex cell has 26
The answer is A
Explanation:
According to the question, the snapping turtle possesses 52 chromosomes in its cell. This means that the chromosomal number of its body cell is 52. However, the turtle, which reproduces sexually will produce gametes or sex cells via meiosis. Meiosis is the kind of cell division that results in daughter cells (gametes) that have a reduced number of chromosomes (by half).
Based on this, the diploid cells (2n) of the turtle with chromosome number 52 will undergo meiotic division to produce haploid gametes or sex cells (n) with chromosome number 26.
N.B: Diploid (2n) means two complete sets of chromosomes while haploid (1n) means one complete set of chromosome.
The body cell of the turtle contains two set of chromosomes received from each parent, hence, making it Diploid (2n). However, meiosis will reduce the chromosome number to one set in each gamete i.e. haploid (n).
The main function of the PNS is to connect the CNS to the limbs and organs. The PNS sends information to the CNS as quickly as possible.

The argument or the reason that Dr. Douglas used with Dr.
Brodus in allowing the Tuskegee study to continue despite of certain
circumstances was because of validation in terms of the autopsy in which he
stated that is needed in order to know whether the study is reliable and it is considered
to be science.
Answer: Either the cell wall or the membrane
Explanation:
The cell wall proctects the cell while the membrane forms structures inside of the cell
Answer: 1. Carbon is removed by the producers, and added by the consumers.
Explanation:
Carbon cycle is one of the important biogeochemical cycle. The carbon is present in the atmosphere to an appreciable amount in the form of carbon dioxide. This is absorbed by the producers like plants and other autotrophs to conduct the process of photosynthesis. The autotrophs are consumed by the consumers and the carbon dioxide is released by them in the form of fecal matter. The decomposition of these consumers by the soil microbes also add carbon dioxide to the atmosphere.
