<span>All cells have the same DNA. They are different because different genes have been locked up and only some of them are expressed. The process began in the embryonic stage, when stem cells are turned into different types of cells by turning off some of the genes. Scientists have been looking for ways to reverse the process, meaning turning specialized cells back into stem cells. Some success has been reported using different methods. The latest one uses a weak acid to stress the cells.</span>

a
Explanation:
A spider may produce hundreds of eggs, only a few of which may survive. This is an example of a. overproduction.
Answer:
Autotrophs are organisms that use light energy or energy stored in chemical compounds to make their own food.
1st order heterotrophs are organisms that eat only plants
2nd order heterotrophs are organisms that eat herbivores
3rd order heterotrophs: organisms that eat herbivores and other carnivores
Top group: carnivores
Explanation:
Producers are named as such because they produce their own food either by photosynthesis or chemosynthesis. These organisms are called autotrophs and include plants.
There are various levels of consumers. The first is first order heterotrophs, which feed on the producers. These are herbivores and include, for example, a deer feeding on grass.
The next is second order heterotrophs, which feed on the first order heterotrophs. E.g. an owl eating a mouse. These are carnivores
The next layer are also carnivores, third order heterotrophs which eat second order heterotrophs, for example a lion eating a zebra.

In clockwise hemisphere would you find this motion. As shown in picture the arrow is facing toward the south to north east direction.
<h3>
In which direction earth rotates?</h3>
Earth rotation direction is west to east, that appears counterclockwise when viewed from above the North Pole.
Any circle drawn around the earth divides it into two equal halves called hemispheres. There are four hemisphere northern, southern, western, eastern hemisphere on the earth.
