A study was conducted in a nursing home to examine the association of hand-washing and Gastroenteritis. Residents with the disea

cupoosta [38]

Answer:

The correct answer is case control study.

Explanation:

A study in which a comparison is made between the patients carrying the disease with the patients not carrying the disease is known as the case-control study. In the mentioned study, the one carrying the disease is termed as cases, and the one that does not possess the disease is termed as controls.

This form of study is generally done to predict the association between the disease and the risk factor. In case-control studies, only observation is done as no attempt is made to change the course of the condition. The prime objective of the study is to predict the exposure of the risk elements for the individuals present in two groups, that is, controls and cases. This form of study is also called case-referent studies or retrospective studies.

Explain Gynecomastia in males.

PolarNik [594]

Gynecomastia is an increase in the size of the mammary gland in men. The condition can occur in one or both breasts. It starts as a small mass under the nipple, which can be sensitive. One breast can be bigger than the other. Its cause is an imbalance between the stimulatory effects of estrogen (female sex hormones) and the inhibitory effects of androgens (male sex hormones) in the breast tissue, when the first ones increase, or the second ones descend.

Gynecomastia is a problem relatively common in the population, and there are three prevalence peaks throughout life:

Newborns: Between 60 and 90% of newborns have gynecomastia, produced by the passage of maternal estrogens through the placenta. It is a transient gynecomastia that disappears in about 2-3 weeks.

Puberty: Gynecomastia in puberty affects mainly young people aged between 10 and 14 years, and is due to the transient and physiological increase in estrogen that occurs at this age.

Elderly: Is due to an increase in fatty tissue with a greater peripheral aromatization ( a process that occurs in adipose tissue and that involves the conversion of androgens into estrogens), a decrease in the production of testosterone by the testes and the use of drugs.

Can someone explain how it is possible for a single molecule of steroid hormone to create a significant and lasting response in

Mars2501 [29]

Steroid hormone

The cell signaling pathways induced by the steroid hormones regulate specific genes within the cell's DNA. The hormones and receptor complex act as transcription regulators by increasing or decreasing the synthesis of mRNA molecules from specific genes.
Steroid hormones are not able to target every cell within the body, so the overall response is slower. They bind to receptors on the cell's surface and the receptors aid in helping the steroid hormones enter the cell.
Hormones work by binding to protein receptors either inside target cells or on their plasma membranes. The binding of a steroid hormone forms a hormone-receptor complex that affects gene expression in the nucleus of the target cell.
Steroids pass into a cell's nucleus, bind to specific receptors and genes and trigger the cell to make proteins.

3' CTGGCTAC5' 5' GACCGATG 3' 3'CUGGCUAC 5'

Explanation:

Some of the sequence of DNA given is in 3' to 5' direction, mRNA sequence is also given.

The DNA is double stranded helix which replicates by semi conservative mode. The two strands unwind to act as a template for other strands. In transcription the 3' to 5' strand acts as a template because RNA synthesis takes place in 5' to 3' direction. mRNA is single strand. It has nucleotides in it from which 3 base pairs acts as a code for amino acid.

The following table shows DNA strand having complementary sequaence and mRNA synthesized.

Many molecules are moved through the body by

Solnce55 [7]

Question: Many molecules are moved through the body by?

Answer: The molecules are moved through the body by uses special transport proteins to move molecules across the membrane that cannot pass thorough on their own. Usually large molecules. Carrier proteins blind and carry the molecules across the cell membrane. They provide an open channel of passageway through the cell membrane for molecules to move across.

Hope this helps!.
