increased overall ocean salinity
B
decreased global polar ice melting
с
increased overall atmospheric humidity
D
decreased global surface temperatures

Answers

Answer:

C) Increased overall atmospheric humidity

Increasing overall atmospheric humidity is the result of an increase in the amount of greenhouse gases in the atmosphere. Therefore, option C is correct.

What are greenhouse gases?

The gases that trap heat in the earth's atmosphere are referred to as greenhouse gases. The earth's surface warms during the day when the light beams through the atmosphere. The earth's surface cools at night, redistributing heat into the atmosphere. However, part of the heat is captured by the atmosphere's greenhouse gases.

Due to minute concentrations of water vapor (H2O), carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) in the atmosphere, the Earth has a natural greenhouse effect.

Increasing overall atmospheric humidity is the result of an increase in the amount of greenhouse gases in the atmosphere. Therefore, option C is correct.

Draw the structure of ATP molecule and explain how it is formed​

Answers

ATP is formed from the breakdown of glucose molecule in mitochondria of the cell.

ATP molecule is formed in the process of respiration i.e. aerobic and anaerobic. During aerobic cellular respiration, glucose reacts with oxygen in the mitochondria of the cell, forming ATP that can be used by the cell in different cellular activities. When glucose reacts with oxygen, three molecules are formed i.e. ATP, Carbon dioxide and water. ATP is used by the cell whereas the Water and carbon dioxide molecules are waste materials which are removed from the cell so we can say ATP is formed from the breakdown of glucose molecule in mitochondria of the cell.

HELP QUICKLY Why are the deepest high tides so deep and the shallowest low tides so shallow? Hint: how are the Earth, Sun, and Moon aligned?

Answers

There are different kinds of tides. This change occur because  when the gravitational pull of the sun works along with the gravitational pull of the moon on Earth, it leads to the oceans bulging out.

This result above makes the high tides as been little higher and low tides been little lower than normal.

Spring tides are known to be the deepest as oceans levels are highest in this kind of tide. The neap tides are known to be the shallowest.

This often occurs when the moon, earth, and sun are said to be at a right-angled plane.  Therefore, the gravitation pull of the moon and sun on the oceans do counteract each other making its net effect is smaller.

What are temperate grasslands?

Temperate grasslands are biomes characterized by vast expanses of open grasslands with few trees or shrubs. These ecosystems experience a wide range of temperature fluctuations between seasons, with hot summers and cold winters. As a result, animals that live in temperate grasslands have evolved adaptations that enable them to survive in this challenging environment. One of the most common adaptations of grassland animals is the ability to dig burrows. Burrows provide shelter and protection from predators, as well as a stable microclimate for animals to live in.

Answer:: De-termination could offer experiences into development and normal assets that are at present inaccessible to us.

2: Compromised or harmed biological systems could be reestablished with the assistance of specific now-wiped out species.

3 In the event that  people  drove plant and creatures species into termination, maybe we owe it to these species to attempt to bring them back.

4 De-elimination could be a major advance forward for hereditary designing.

There are loads of valid justifications to bring back wiped out creatures. All creatures perform significant jobs in the environments they live in, so when lost species are returned, so too are the 'positions' they once performed. Wooly mammoths, for instance, were nursery workers. ... It very well may be something similar for other de-wiped out creatures, as well.

Zeroing in on de-elimination could think twice about by redirecting assets from protecting environments and forestalling more current eradications. It could likewise diminish the ethical load of annihilation and backing for imperiled species, sending the mixed signal that resuscitating a wiped out creature or plant is trifling
