Correct answer is B.
Explanation:
In their nucleus cells contain DNA. The DNA has information about size, shape and function of each cell. When the cell reaches it's full size it stops growing and starts doing whatever it's function is. If more cells are needed then the cell replicates. This explanation excludes answers A and C.
Male and female sexual cells are used to conceive a baby. These cells combine to form a new type of cells. In the first few weeks all types of cells are created. Then the creation of new types of cells stops and existing cells multiply in order to achieve needed number of cells. This explanation excludes answer D.
When we compare an adult person and a baby we can see that, for example, an adult has bigger bones than a baby. This was result of increasing number of existing types of cells without creating any new type.
Answer:
abyssal clay is not an example of biogenic sediments .
Explanation:
Any sediment containing more than 30% of organic matter in it , is called as biogenic sediment or biogenic ooze.
The two most common types of biogenic oozes are calcareous and sileceous.
abyssal clays are the fine grained sediment particles that are settled in the deep ocean basins.
abyssal clay mostly consists of land derived eroded particles and have less than 30% of organic matter in them ,
Hence , abyssal clay is not an example of biogenic sediment.
It is called seismic waves. That should help:)
Answer: The Australian continent.
<h2>
Answer: India, Pakistan, Bangladesh, Nepal, Bhutan, Sri Lanka and Maldives</h2>
The Indian subcontinent (also called South Asia) is the geographical region that is currently divided among the states of India, Pakistan, Bangladesh, Nepal and Bhutan. However, for cultural and geographical reasons, the island states of Sri Lanka and Maldives are also considered part of this subcontinent.
This landmass, which is a peninsula in the southern region of Asia, is mostly situated on the Indian Plate. In this sense, it is considered a subcontinent because it belongs to a continent, but is smaller compared to a continent.
Nevertheless, this region is part of a distinct landmass that was originally larger, but after the separations due to the movement of tectonic plates, it became part of Asia.
