How did land whales eventually became aquatic?
cluponka [151]

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.

A Chlorella cell viewed through a microscope is 0.00005 m wide when the magnification is 2000.
juin [17]

Answer:

0.0025micrometer.

Explanation:

To calculate the actual size of the image, the formula to be used is

Actual size=Image size÷magnification.

The image size is 0.00005 wide

Magnification is 2000

First, convert the image size to micrometer.

=0.00005 × 1000000

50micrometers.

Actual size= 50÷2000

Actual size = 0.0025

kvv77 [185]

Answer: C_6H_{12}O_6

Explanation: Photosynthesis is a phenomenon in which green plants containing chlorophyll use sunlight as a source of energy to convert carbon dioxide and water to form glucose and oxygen.

Photosynthesis is the process used by plants, algae and certain bacteria to convert energy from sunlight and turn it into chemical energy in the form of glucose which is used a s a source of energy by many organisms.

The balanced chemical equation for photosynthesis is written as :

6CO_2+6H_2O\overset{sunlight}\rightarrow C_6H_{12}O_6+6O_2
