<h2>
Answer:</h2>
<u>a. Earth quakes</u> are common.
<h2>
Explanation:</h2>
"Ring of Fire" is a significant region in the bowl of Pacific Ocean where numerous earthquakes and volcanic ejections happen. In an enormous 40,000 km horseshoe shape, it is related to an about nonstop arrangement of maritime channels, volcanic circular segments, and volcanic belts and plate developments. It has 452 volcanoes.
About 90% of the world's tremors and about 81% of the world's biggest seismic tremors happen along the "Ring of Fire". The Ring of Fire is an immediate aftereffect of plate tectonics: the development and impacts of lithospheric plates, particularly subduction in the northern segment.
What do you mean <span>It has been observed that certain species of insects which had not previously caused significant harm have become serious pests. the best explanation for this phenomenon is that the pesticide killed off predators which had previously held this species in check. a mutation occurred in the species. the pesticide increased the vigor of the species. was able to be used by the pest as an additional food source is also a reproductive for some insect species. </span><span />
Answer:
ribosome, cell membrane, nucleus
Explanation:
The organelles that perform similar functions in both plant and animal cells among the listed organelles would be <u>the ribosome</u>, <u>the cell membrane</u>, and <u>the nucleus.</u>
First of all, chloroplast and cell wall are limited to the plant cell only. Animal cells do not have these organelles.
The ribosome functions as the site of protein synthesis in both plant and animal cells. The cell membrane acts as a channel for the control of the movement of materials in and out of the cells and is found in both plant and animal cells. The nucleus is also present in both cells and serves as the control unit of the cell by housing the genetic materials and dictating how the cells will behave.
Answer:
For recessive traits to be observed, dominant genes must be absent.
Explanation:
There are 3 possibilities for the genes: AA, Aa, aa.
in both AA and Aa, there is a dominant gene present. If a dominant gene is present, it will always show the dominant trait.
In aa, there is no dominant gene present, and there are only recessive genes. Because of this, the recessive trait is observed!
Answer:
Cool air falls, this is associated with greater pressures areas.
Warm air rises, this is associated with low-pressure areas.
<u>Explanation:</u>
Due to the <em>differences in air pressure</em>, <em>the wind is blown from 'one location to another location'</em>. The cool air is denser than warm air hence the cool air fells which has high density. The warm air has less density and it rises. So the cool air is related to greater pressure areas and warm air is related to lower pressure areas.
