<span>In the question,'when a doctor is able to determine the sex of the foetus, during an ultrasound scan, what stage of development is the foetus in, the correction option is D, that is, the second trimester. Human pregnancy usually lasts for an average of nine months. The nine months are divided into three parts of three months each called trimester. The first trimester is made up of the first week of the pregnancy to the twelfth week. During this period, the foetus is just developing and can not be picked up easily by an ultrasound scan, but by the second trimester, which is week thirteen to week twenty four, the foetus would have develop enough to be picked up by the ultrasound scan. At this stage, the doctor can easily determine the sex of the foetus whether it is a boy or a girl.</span>

krek1111 [17]

Explanation:

Meiosis is the formation of reproductive cells, like the egg in the fallopian tube; if not fertilized by sperm, it is expelled by the menstrual cycle.

Some conditions during fertilization can be disrupted by an egg attaching to the fallopian tube instead of the uterus causing an ectopic pregnancy. Arranging chromosomes in a different way causes congenital defects like color blindness, crohn's disease down's syndrome, etc.

When you drink a cup of milk and eat a peanut butter sandwich, what happens to the protein in the milk, peanut butter, and the w
Butoxors [25]

Answer:This food combination is made up of protein, Carbohydrate and fats.

Mechanical digestion of the carbohydrate begins in the mouth during chewing of the sandwich-whole bread. The starch in the bread is broken down by enzyme amylase in the saliva to maltose and this begins chemical digestion. Generally starch-carbohydrate digestion begins in the  mouth.

The digesting food moves by peristalsis through the oesophagus to reach the stomach -this is ingestion.

In the stomach milk digestion begins by changing it to curds for easy absorption; Enzyme pepsin acts on the protein fragments of the  milk to converts it to small fragments. While enzyme Ligual lipase converts the fatty components to  smaller fragments .Both  enzymes use the acidic environment provided by the HCL  acid in the stomach.

Jelly is Jam, which is made of fruit juice,  thus it contains sugars, pectin and water. Therefore it digestion begins in the stomach.

These(Chyme-partially digested food) are pushed to the small intestine,where pancreatic  and intestinal enzymes , acts on the carbohydrate, protein, and fats. and converts them to monomers/ end products. Thus  starch to glucose, protein to amino acids., and nucleic acids  monomers.

Emulsification by the bile acids from the gall bladder and the liver, converts the fats to globules for easy absorption.This is together with  the activity of  enzymes e.g lipase, the fat is converted to fatty acid.

The amino acids and glucose monomers are absorbed directly into the blood stream through the villi on the wall of the duodenum. Villi increases surface area for absorption .

However  fatty acids  are larger than the blood vessels diameter. But small chains fatty acids  can enter the blood capillaries directly.However longer chains are converted to compound Chylomicron.(cholesterol and protein coat) .This is known as the( the Chyle).It  is  moved into the Lacteal where they are transported to the lymphatic vessels to reach the left subclavian vein enroute  the blood stream. by-passing the liver.

Massive water absorption occurs in the large intestine.The undigested materials from the above food substances  are moved into the large intestine,  and moved out as faeces.
