The correct option is A.
Light microscope can be used to view living cells while electron microscope can not be used to view living cells; it can only be used to view dead specimens.
Electron microscope can not be used to view live specimens because, the preparation process used to prepare specimens for viewing under this microscope will kill the specimen.

lyudmila [28]

Answer:

Trend analysis

Explanation:

Trend analysis is a technique which is used during technical analysis in the prediction of the prices of future stocks based in the currently observed trends. The basic idea behind the trend analysis is the success or failure of a trade in future can be estimated by the conditions of the trade in past. Thus in this analysis the upward or downward growth trend of a business is used in prediction of future of business and in this way it is helpful for the investors to be sure that they should invest their money in the business or not.

Gestational diabetes occurs when a pregnant woman has high levels of blood sugar. Cells in the pancreas usually keep blood sugar
Ahat [919]

Answer:

environment controlling gene expression  

Explanation:

Gestational diabetes generally occurs in pregnant women. The sugar level in the bloodstream becomes little high than the normal range during pregnancy. But the glucose level returns to normal after child birth.

The pancreas secrets insulin which helps to lower the blood sugar level in the body. But during pregnancy, the placenta releases some of the hormones which dilutes the effect of insulin. This is known as insulin resistance. So now the pancreas secretes more of insulin to overcome this insulin resistance for the body. Now if a woman during pregnancy does secrete more insulin, the glucose level increases in the body and the woman develops gestational diabetes.

Gestational diabetes greatly depends upon obesity and the ethnicity of the women, but a definite genetic link has not been identified.

This it is a result of the environment control gene expression.

The correct sequence for aerobic metabolic breakdown of glucose is
Luba_88 [7]

Answer:

a. glycolysis—preparatory reaction--cirtric acid cycle--electron transport system

Explanation:

  • Glycolysis is the first stage of cellular respiration that occurs in the cytoplasm of the cell. During glycolysis one 6 carbon glucose is converted into two molecules of 3 carbon pyruvic acid or pyruvate.
  • In the preparatory reaction, the pyruvate converted into a two-carbon molecule called acetyl CoA. In this reaction, a carbon dioxide molecule is released and a molecule of NADH is released.
  • The citric acid cycle begins with the reaction of the acetyl CoA with a four-carbon molecule in the mitochondrisl matrix. It goes through a cycle of reactions regenerating the four-carbon starting molecule. ATP, NADH and FADH₂ are produced.
  • The electron transport system is the terminal step of aerobic respiration that operates on the inner membrane of the mitochondria. Reduced coenzymes NADH and FADH₂ move along electron transport system release high-energy electrons and produce ATP.
