Answer:</h2>
To obtain more amount of single cell, a method called <u>cell culture</u> is employed.
<h2>
Explanation:</h2>
Cell culture, otherwise called limited cells, will be cells that are legitimately arranged from a life form's tissues. Whenever placed under the correct conditions essential cells will develop and multiply, however they are just ready to do so a limited number of times. As far as possible is identified with the telomere length toward the finish of the cell's DNA.
As cells experience every cell division, a little portion of the telomere is lost after each time DNA is copied. This procedure in the long run prompts a phase of senescence, where the cells can never again separate. Persistent cell lines, then again, can get away from the ordinary limitations of the cell cycle and develop inconclusively, making them incredibly helpful for long haul inquires about.
Answer:

Explanation:
Photosynthesis is a special process that certain organisms (plants, algae, and some bacteria) undergo to create "food".
This turns light energy, carbon dioxide, and water into glucose and oxygen. The glucose becomes the food for the organism, because it is turned into ATP during cellular respiration. The ATP is energy that fuels the processes, like growth, repair, and transport.
This process occurs because of the <u>sun</u>. It provides the light energy needed for the reaction. Organelles inside of the cells, called chloroplasts, contain a pigment (chlorophyll) that captures this energy.
I would say d because mars for us maybe was with ice till the big bang and made mars really hot.
Answer:
Genetic variation is the difference in DNA among individuals or the differences between populations. There are multiple sources of genetic variation, including mutation and genetic recombination.
Explanation:
A field habitat vegetated by grass and other non-woody plants (grasslands) is known as a meadow. They are of ecological benefit as they are open, sunny regions, which fascinate and support fauna and flora that could not survive in other conditions.
In the given case, when a fungus colonizes the meadow and destructs the majority of its vegetation, which comprises species of small shrubs and grasses, then this may result in the decline of herbivore species due to lack of vegetation on which they survive, which will eventually result in the reduction of carnivore species, as they feed on herbivores.
