Answer:
D) 10.5
Explanation:
DNA which is known as Deoxyribonucleic acid have base pairs which are the building blocks of the DNA. The base pairs are known as Adenine-Thymine base pair and Guanine-Cytosine base pair.
DNA studies by scientist however have found that there are approximately 10.5 base pairs in two turns of a B-DNA double helix.
Answer: C
Explanation:
In substrate level phosphorylation energy is trapped directly from the substrate, without the help of the complicated electron transport chain reactions.
Substrate-level phosphorylation refers to the formation of ATP from ADP by directly phosphorylating ADP from a high energy substrate catalyze by an enzyme.
But when energy is trapped by oxidation of reducing equivalents such as NADH, it is called oxidative phosphorylation.
Examples of substrate level phosphorylation in glycolysis include conversion of 1, 3-Bisphospho glycerate to 3-Bisphospho glycerate and conversion of phospho enol pyruvate to pyruvate
Earth's crust lies above the mantle and directly interacts with living organisms.
Earth is divided into four systems: the lithosphere, hydrosphere, biosphere and atmosphere. The lithosphere is the solid outer layer of Earth that consists of the crust and the solid upper part of the mantle and is divided into the tectonic plates. The crust is a thin cell on the outermost zone of the Earth, lying just above the mantle.
