A. Midline 2 to 3 cm (0.8 to 1.2 in) above the symphysis pubis. Normal ultrasounds use sound waves to produce images, but unlike Doppler devices, they are unable to show blood flow.
The Doppler device ultrasonography is a non-invasive diagnostic that gauges the blood flow through your arteries by reflecting high-frequency sound waves off circulating red blood cells. Doppler ultrasound uses sound waves to monitor artery blood flow. It is used to examine the blood flow to the placenta, uterus, and unborn child throughout pregnancy.It has advantages when used in high-risk pregnancies where the health of the unborn child is a worry. Nowadays, most pregnant women have an ultrasound before 12 weeks. Typically, a fetal Doppler test is performed between weeks 13 and 28 of your second trimester.

Answer:
Ureter
Explanation:
Ureter -
Ureter is a narrow tubes which carry urine from the kidneys to the bladder .
The muscles in the ureter walls relax and tighten in order to force the urine downwards , out of the kidneys .
Hence ,
The ureters are responsible to conduct the newly formed urine , that is produced in the renal pelvis to the urinary bladder .
Answer:
CD4 cells are a type of immune cell found in the human body. These cells protect us from infections. CD4 count is a measurement of the number of CD4 cells in a blood sample. It is also used to monitor the progression of HIV infection.
In an HIV-negative adult, the normal range of CD4 count is 500-1500 mm3.
In AIDS there is the destruction of the blood CD4 lymphocytes by the virus.
Explanation:
CD4 cells are a type of immune cell that is found in the blood. This cell count is a measure of the number of these cells in a milliliter of blood. It is an important indicator of immune health.
When the CD4 count gets lower than 200 mm3 the patient is more prone to get opportunistic infections like rare fungal infections, Tuberculosis, Mycobacterial infections, parasitic infections, etc.
The CD4 count is used to measure to identify an immune deficiency in people.

More recently, medicine and science has taken a <u>prevention</u> stance, or identifying the factors that cause specific mental health issues and implementing interventions to stop them from happening, or at least minimize their deleterious effects.
<h3>What is prevention?</h3>
In Science, prevention can be defined as a wide range of activities generally referred to as interventions, which are typically aimed and focused on stopping or reducing (mitigating) risks or threats to the health and well-being of a living organism.
<h3>The types of prevention.</h3>
Basically, there are two major types of prevention and these include the following:
- <u>Primary prevention:</u> it is aimed at preventing an injury or disease before its occurrence.
- <u>Secondary prevention:</u> it is aimed at reducing the impact of an injury or disease that has occurred already.
In conclusion, medicine and science is focused on a <u>prevention</u> stance, or an identification of the factors that cause specific mental health issues while implementing interventions that would stop them from happening, or at least mitigate (minimize) their deleterious effects on a living organism.

Answer:
Catabolism is method by which large complex molecules like lipids, proteins and carbohydrates are broken down into the simpler smaller molecules.
Protease or peptidase are the enzymes that catalyzes the breakdown of proteins into amino acids or smaller polypeptide units. The protease enzyme pepsin is secreted in the<u> stomach</u>; and trypsin and chymotrypsin is secreted in the<u> pancreas.</u>
Amylases are the enzymes that breaks down the complex carbohydrates to simple sugars. The enzyme salivary amylase is secreted by the <u>salivary gland in mouth</u> and the enzyme pancreatic amylase is secreted by <u>pancreas.</u>
Lipases are the enzymes that catalyzes the breakdown of lipids or fats. Lipases are secreted in the <u>mouth, stomach, and pancreas.</u>
