Answer:
Their survival is correlated to water clarity because kelp, the main food of otters' prey (sea urchins), needs clear water to thrive.
Explanation:
Otters are extremely important organisms, also known as "<em>keystone</em>" species. They keep aquatic ecosystems healthy because they control other populations such as sea urchin populations that consume kelp, sometimes in excess.
For this reason, otters prefer inhabiting near the kelp, which generally grows in clear waters near shores. They also prey on crabs, marine snails, squid, etc. as they possess the ability to dive as deep as 250 feet.
Therefore, their survival is correlated to water clarity because kelp, the main food of otters' prey (sea urchins), needs clear water to thrive.

Alpine tundra occurs in mountains worldwide. The flora of the alpine tundra is characterized by dwarf shrubs close to the ground.
Answer: Cell
Explanation:
The cell is the structural and functional unit of life. It is the the most basic level. A life starts from a single cell.
When a male and female gamete(germ cell) fuse together they form zygote. Firstly it is a single cell surviving inside the mother's womb.
Then differentiation takes place and the cell keeps on dividing to form different tissue layers and then organs form which makes a complete baby. Hence, zygote and germ cell are cellular level of organization.
Answer:
10 chromosomes
Explanation:
<u>Ten (10) chromosomes</u> would be found in each cell of Arabidopsis thaliana during prophase.
The prophase stage represents the first stage of the mitotic division immediately after the interphase. A diploid cell has 2n number of chromosomes and the ploidy level of a cell remains intact throughout the interphase to the prophase stage of mitosis.
<u>At the prophase, the chromosomes of a cell only condense and become visible under the microscope. Each chromosome is seen as being consisting of two sister chromatids joined together by a structure known as the centromere. </u>
<em>Hence, the number of chromosomes in the cells of Arabidopsis thaliana would remain the same even at the prophase stage of mitosis.</em>
