Answer:

False

Explanation:

Most scientists were not yet concerned about global warming. This was because the major issue during the period between 1940 and 1970 was global cooling with little or no attention on global warming.

However things started to change due to more pollution as a result of technological advances. Global warming started becoming a concern between 1970s and 1990s because of the increase in steady surface temperature.

Explain the process of mitosis in a tissue culture for cancer cells.
Tresset [83]

The cells divide and die at a relatively constant rate. Thus, the body permanently contains an identical number of cells. Everything is under the control of genes preventing uncontrolled proliferation.

However, they are sometimes victims of mutations and, in a certain context, the cells begin to multiply in an anarchic and uncontrolled way. It is the tumor, which can be benign (non-cancerous) or malignant (cancerous). Sometimes the body manages to get rid of it. Other times, unfortunately, this is not the case.

The cancer cell is an abnormal cell,

* which loses certain normal characters (Morphological and functional) and acquires

new specific characters that are transmitted to the child cells.

* and multiplies in an anarchic and autonomous way escaping the mechanisms of  regulation of cell division.

Cancer is characterized by a multiplication of cancer cells that divide by  mitosis. The number and the atypical character of the mitoses are in favor of the malignancy, One finds:

• Increase in the number of mitoses with shortening of the interphase.

• Abnormal, multipolar mitosis with irregular distribution of chromosomes.

It tends to expand (expansive character) in an unlimited way at the expense of the fabric in the  which it originated, but while maintaining a certain degree of differentiation related to its  original fabric.

Why lactic acid fermentation is considered a type of Anaerobic respiration, when both of them are different things.
zepelin [54]

Answer:

Lactic acid fermentation is a type of anaerobic respiration

(or fermentation) that breaks down sugars to produce

energy in the form of ATP. It is called anaerobic because it

occurs in the absence of oxygen . Lactic acid is generated

as a byproduct of this reaction, which is what gives this

type of fermentation its name.

and also Lactic acid fermentation is the type of anaerobic

respiration carried out by yogurt bacteria (Lactobacillus

and others)
