It is one of the essential building blocks of life. Carbon is integral because of its unique ability to form four different bonds with other elements.
They exhibit considerable molecular complexity and diversity
Answer:
2. Not move
Explanation:
An object at rest will stay at rest unless acted upon by an unbalanced force.
Answer: option d.hydrogen bonds between nitrogen base Pairs
Explanation:
DNA is called a Deoxyribonucleic acids, it contains hereditory information in the cell. DNA is located in nucleus of human cell. DNA consist of nucleotide strands that comprises of a sugar and oxyribose bound on a partto a phosphate group and bound on the other part to a nitrogenous base. The Nitrogenous base consist of Adenine, thymine, guanine and cytosine which are complementary base Pairs. They are grouped into 2 distinct classes called purines (double-ringed structures) and pyrimidines (single-ringed structures). The nitrogenous bases forms a ladder and pairs with bases on the other side commonly called rungs. Each complementary nucleotides purine with pyrimidine are held together by hydrogen bonds.A hydrogen bond is a known as chemical bond that is relatively weak and occurs only between hydrogen atoms along with or and electronegative atoms, e.g oxygen, nitrogen e.t.c. Hydrogen bonds usually occur in short length or distances and are formed quickly or easily and ca also broken.
Answer:
Sunlight.
Explanation:
Sunlight is responsible for proper functioning of stomata present on the leaves because the stomata only opens when there is sunlight and when the stomata opens, carbondioxide gas is absorbed by the leaves from the air while the water is taken from the roots which combines together to form glucose and oxygen. Glucose is stored in different parts of the plant while some oxygen is used by the plants in the process of respiration while the remaining oxygen is released in the atmosphere through stomata.
