Secretion of human chorionic gonadotropin [HCG] only occur during pregnancy in the placenta. The concentration of this hormone increase rapidly during the first three months of pregnancy; the amount in the blood stream doubles every two to three days as the development of the placenta and embryo progress. The hormone reaches its maximum concentration peak around the sixth week of pregnancy and after this, its concentration decline.
Answer:

Explanation:
All the sensory information through sensory neurons must pass through the thalamus.
<u>Thalamus:</u>
- connects cerebral cortex and midbrain.
- collects information from the midbrain and passes it to the cerebral cortex.
- is involved in more functions such as; detects sensations of visual, auditory, and gustatory systems.
- is concerned with memory, emotions.

The question is asking to state the end result of Eukaryotic cell cycle, base on my research and further investigation, I would say that the correct answer would be that there is No parent cells and two daughter cells. I hope you are satisfied with my answer and feel free to ask for more
Answer: they showed the body of an organism not the activities
Explanation:
PCR technique is important in STR profiling in order to amplify and detect the number of Stars at a specific gene loci.
<h3>What is Short Tandem Repeat (STR) profiling?</h3>
Short Tandem Repeat profiling is a technique in molecular biology used to compare allele repeats known as STRs at specific loci in DNA between two or more samples.
The PCR (polymerase chain reaction) technique used in STR profiling involves making multiple copies is a particular segment of DNA in order to make enough quantities detectable in the analysis.
Therefore, PCR technique is important in STR profiling to detect the number of Stars at a specific gene loci.
