You are correct, A is the right answer.
Because there is more water outside of this cell, there will be a net movement of water into the cell - osmosis
Answer:
This composition of nucleotide given in the question do not obey the chargaff"s rule.
Explanation:
According to chargaff"s rule the total number of purine bases will be same to the total number of pyrimidine bases that is
Adenine+Guanine=Thymine+Cytosine
But here the above quation is not maintained because according to the question A+G=49%
and T+C = 51%.
Such DNA is replicated by rolling circle model.
Answer:
As the temperature of the water goes up, the amount and spatial extent of the kelp goes down. These changes could result in dramatic habitat loss leading to reduced ecosystem productivity and the extinction of many invertebrate species.

Besides producing sugar for itself a plant also needs to absorb nitrogen to build proteins, salts to make concentration gradients and potassium to make enzymes.
<u>Explanation:</u>
Plant sugar is glucose and plants produce it by the process of photosynthesis making use of energy from sunlight, carbon dioxide absorbed from the atmosphere and the presence of chlorophyll in its parts. Plants also require components other than this. Nitrogen is essential to make proteins and it cannot be directly absorbed from the atmosphere but has to be absorbed from the soil.
Potassium is an essential component which is absorbed from the soil. It facilitates the activation of enzymes which play a crucial role in plant metabolism. When plants lack potassium they won’t have enough energy for proper growth and will have poorly formed roots and weak stems.
A solution that has a pH of 6.8
it is <em>acidic</em><em> </em>as it has got ph value less than 7....But as it has got ph value near to 7 it is weak acidic..
