Biology
1 answer:
LenaWriter [7]2 years ago
4 0

Answer:

Apoptosis does not involve:

c. lysis of the cell

Explanation:

Apoptosis is a programmed cell death that occurs under normal physiological conditions and in a controlled manner. Normally seen in cell turnover, embryogenesis, also involved in processes of immune, nervous and endocrine systems.

The main morphological and biochemical changes seen during the apoptosis are the fragmentation of DNA by endonucleases, nuclear, chromatin and cytoplasmatic condensation, apoptotic bodies formation (membrane bound-vesicles form of cell parts) and the phagocytosis (digestion) of those bodies by the scavenger cells.

Apoptosis is regulated by cell- signaling pathways, the caspases, a family of cysteine proteases, are the ones involved in the process.

In the process there is no lysis of the cell as this could lead to a inflammatory response (just happens in necrosis) which would affect contiguous cells, and will involve immune cells. In apoptosis there is just a membrane blebbing, but it does not loss its integrity.

A, B, and C make no sense

A makes no sense because Methane is lighter than air, and so the Methane would stay higher in the atmosphere, so it would not seep into the ground, it would remain in the air.

B makes no sense because Burning fossil fuels causes air pollution by increasing the amount of carbon dioxide in the air. the only way that carbon dioxide could pollute water is if it is combined on a molecular level, plus carbon dioxide does not inhibit the process of water being evaporated by the sun.

C also makes no sense because Deforestation causes acid rain by increasing carbon dioxide not decreasing carbon dioxide in the atmosphere.

so therefore by elimination your answer is D

The government of a flood prone region wants to implement some measure to reduce risk of floods. Which method is likely to reduc
Sonja [21]

Answer:

The correct answer is "preservation of wetlands".

Explanation:

Wetland are areas of lands that are saturated with water, usually comprised by marshes or swamps. Preservation of wetlands help to reduce the risk of floods because wetlands temporarily store and slow the release of stormwater. It has been reported that areas where wetland have been lost, the chances of flood increases by as much as 80 percent. The government of a flood-prone region would likely reduce the risk of floods by preserving its wetlands.

soldi70 [24.7K]

Answer:

<h2>C-A-B</h2>

Explanation:

Given

As given: A and B are 30 map unit apart

A and C are 15 map unit apart

B  and C are 45 map unit apart

So the sequence of genes : according to the map unit distance is:

C-A-B

C-15-A-30-B

C-A=15

A-B=30

C-B= 45.

correct order of genes is C-A-B .
