Answer:
Water and polymers.
Explanation:
Dehydration reaction may be defined as the reaction in which a water molecule is released during the process of reaction. Large molecules are joined together by the process of dehydration.
Polymers are formed by reacting the monomers together with a release of small molecules like water. Hence, water and polymers are formed by dehydration reaction.
Thus, the correct answer is option (3).
Answer:
There are many changes that is ongoing on the earth. Some of the changes are short term changes and the others are long term changes.
These changes are due to the effect of human activities or due to natural processes.
The life of organism depends on these geological processes that keeps on going with time. The growth and development of the organism is hampered by these processes.
Change is the rule of nature and it keeps on changing with time. There has been 5 massive mass extinctions which has affected the life of plant and animal species.
Many of the species have been extincted due to this process.
cells in the vegetal half of the embryo should be unpigmented those in the animal half and there should be heavily pigmented.
Explanation:
The Yolk molecules moving in the vegetal halves of the egg which is the case in most of the animals, slows down the cell division. These lesser division area or the zone demarcates the area to be vegetal pole and due to lesser cell division, it becomes unpigmented or less pigmented Based on the observation time and perspect with assuming no movement.
The pole opposite to the vegetal, is animal pole which with absence or less of yolk, gets more ability to divide and hence become more pigmented or heavily pigmented. This brings polarity to the egg and becomes telolecithal egg.
