Explanation:
Answer:
D.-
Explanation:
A control group is needed to carry out the experiment, that control group is the one that is not injected with anything. Ethanol and pesticide need to be injected into separated groups to document whether it is one or the other that is harmful
The primary ethical guidelines that apply to this experiment are those of human experimentation.
The use of humans as subjects of experimentation would seem to demean their human dignity. The issue of abuse of the human subjects and also the prospects of the clinical trial going wrong (such as causing an adverse effect on the subjects) also raise ethical challenges even when the subjects are volunteers. In case of a clinical error, what is the right compensation?
Answer:
2 chromosomes
Explanation:
The cell of an eukaryotic organism like roundworm contains the Nucleus, which harbors the genetic material embedded in the chromosome. The number of chromosomes of that organism is contained in each cell.
Somatic cells, also called body cells, are all other cells asides sperm and eggs, that form the tissues and organs of an organism. Somatic cells are usually diploid i.e two sets of chromosomes from each parent. In this question, the roundworm has 4 chromosomes in its somatic cell.
The reproductive cells or sex cells (sperm and eggs) of an organism always result from meiotic division of specialized cells.
Since meiosis is a kind of division that results in cells with their chromosome number reduced by half (haploid), it therefore means that the ovum and sperm cell will be expected to contain 2 chromosomes each.
This way, when fertilization occurs (sperm and egg fusion), the resulting zygote, which will eventually develop into an adult organism, will have 4 chromosomes.
Answer:
At 4 months old, the baby should receive the vaccines in order to get protected against the diseases like Diphtheria, tetanus and whooping cough, polio, Haemophilus influenzae type b, rotavirus, and pneumococcal infections. Thus, the child in the mentioned case will receive the second dose of DTaP, Hib, IPV, PCV13 and rotavirus vaccine.
