Explanation:
To swim, they move their tails up and down, rather than back and forth as fishes do. This is because whales evolved from walking land mammals whose backbones did not naturally bend side to side, but up and down. ... Whales do the same thing as they swim, showing their ancient terrestrial heritage.
Cetaceans are fully aquatic marine mammals belonging to the order Artiodactyla, and branched off from other artiodactyls around 50 mya (million years ago). Cetaceans are thought to have evolved during the Eocene or earlier, sharing a closest common ancestor with hippopotamuses.
Answer:
A. Nuclear reactors increase thermal pollution
Explanation:
From the analogy provided in this context, we can vividly see that the author is suggesting that the use of nuclear energy causes thermal pollution.
- Nuclear energy is an alternate energy source as identified in the text.
- Since a huge amount of heat energy is generated and they are not all used up, they are released into the ecosystem.
- The earth is usually depicted as heat reservoir.
- Increased release of heat to the environment will cause thermal pollution.
- This increases the ambient temperature of water and degrades it.
Meristematic tissue is the dividing tissue present at the growing regions of the plants. They are meant for growth of an organ Cells of meristems divide continuously and help in increasing the length and girth of the plant
The cells of this tissue are similar in structure and have thin cellulose cell walls
The cells do not contain any intercellular space between them
The cells contain few vacuoles or no vacuoles at all
They are further divided in the following parts
1)Apical meristem
2)Lateral meristem
3)Intercalary meristem
The answer is a im pretty sure
