Answer:
Photosynthesis.
Explanation:
Photosynthesis may be defined as the process by which the plants prepare their own food by the use of sunlight and chlorophyll. The light energy is converted into chemical energy for food storage.
The early environment of the Earth's atmosphere is highly reducing. The photosynthesis at an early environment causes the formation of the traces of oxygen. The water molecule will breakdown into the hydrogen and oxygen by the use of the ultraviolet light.
Thus, the answer is photosynthesis.
SCNT stands for Somatic Cell Nuclear Transfer. It is used for creating an ovum with a donor nucleus. It can be useful in embryology and a donor nucleus.
The steps of SCNT are as following:
<span>d. Isolate donor cells from egg donor and germ cell donor
</span><span>c. Remove and discard the nucleus from the egg cell
</span><span>e. Transfer the somatic cell nucleus into the egg cell
</span><span>a. Stimulate cell division
</span><span>f. Implant embryo into a surrogate mother
</span><span>b. Deliver baby</span>
Answer:
Enzymes are biological catalysts which speed up biochemical reactions.
The more intense the force is of the car hitting something and the faster it goes the longer it's going to take to stop going forward. Lighter cars accelerate faster than heavy cars.
Answer:
<em>The correct option is B) as the light colored moths were seen and eaten, the allele for dark colour became more prevalent in the population.</em>
Explanation:
The process of natural selection tends to favour those organisms which are better adapted to live in an environment. Evolution changes the allele frequencies of a population over time depending on the traits favoured by natural selection.
Before the industrial revolution, the colour of the trees was lighter and hence, the light coloured moths were better adapted to such environments as they could hide from predation. After the industrial revolution, the colour of the woods of trees became darker. The light coloured moths were no more able to hide from their predators and hence their population declined.
