What is the principal source of dissolved substances in the ocean
Ipatiy [6.2K]

Answer:

infiltration

Explanation:

  • As Na and Cl make up much of the dissolved common salts found in the ocean waters, the element in the earth's crust can be easily be dissolved in the rain and river and get carried away from the runoff of the river.
  • Infiltration is process by which water on the ground enters the soil. The porosity of the soil particles on land water determine the infiltration capacity and thus are a major source of dissolved sediments in water bodies.
  • Also, rainfall influences this rate of sediment flows in water all the organic and inorganic matter in the soil is mainly composed and collected from the rain and discharge rate of the soil. Weathering produces mass wasting and erosion of the landforms from the above and thus indirectly related to the dissolved content.

Let's say that Sam and Joe are identical twins. This means they are like clones of each other. They have the same DNA sequences
galben [10]

Answer: No, only identical twins will look identical.

Explanation:

Identical twins are also called monozygotic twins. Such twins are produced by the fertilization of one egg that splits into two. The genes present in these twins are same thus the expression of traits is also same in them and they have the same sex.

Sam and Joe and Maria and Ella are identical twins these pairs are expected to have same genotypic and phenotypic traits. They may be clones of each other. But if Sam and Maria are married and Joe and Ella are also married then their children will have some similar traits in common but their children will not be identical as they are not identical twins as their parents were.

A muscle cell usually contracts or expands simultaneously when one is working or doing some activities like running, exercises, house chores e.t.c

Muscles are flexible fibers that are very essential appendages for locomotion in human beings.

For muscle cells to contract, they are pulled together thereby causing tension in the muscle. When they are relaxed, they move away from one another.

Kay [80]

Answer:

As the erosion happens often, there is a principal way of solving or reducing the erosion, like sea wall.

Sea walls should be formed in places where erosion hits. They serve to stop the water and return it to the sea.

Explanation:

People are the main reason for erosions. They are using explosions for fishing and that is how they are degrading the coastline.

Other ways of stoping the erosion are sand, vegetations, sandbags, etc.
