Answer:
B) Krebs cycle (citric acid cycle)
Explanation:
Glycolysis breaks glucose into two pyruvate molecules. Pyruvate is decarboxylated into acetyl CoA and the reaction occurs in the matrix of mitochondria. In the mitochondrial matrix, acetyl CoA enters Kreb's cycle and is broken down into CO2 and H2O. For one molecule of acetyl CoA, two molecules of CO2 are released as a by-product. Therefore, out of three carbon atoms of pyruvate, two are released as CO2 during Kreb's cycle.

Nuclear magnetic resonance provide information on the structure of a purified protein based on its nuclear spin properties in a magnetic field, whereas X-Ray crystallography uses diffraction pattern of protein in solid phase.
Explanation:
Nuclear magnetic resonance is a spectroscopic technique that involves change in nuclear spin energy in presence of an external magnetic field. It is based on the absorption of electromagnetic radiation in the radio-frequency region.
X-Ray crystallography is a method of determining the arrangement of atoms within a crystal.This technique is based the fact that when a beam of X-ray strikes a crystal, the beam gets diffracted. From the angle and intensities of diffraction a three-dimensional structure of electron density can be determined .
Answer:
In the Cretaceous period, Mesozoic Era forests begin to look like modern day forests and included a variety of conifers and decidous trees.
Explanation:
The Cretaceous period was the last and longest segment of the Mesozoic Era.It lasted approximated 79 million years from the minor extinction events that closed the Jurassic Period about 145.5 million years ago to the Cretaceous - Palogene ( K-Pg) extinction event dated at 65.5 million years ago. This era have seen more dinosaurs than before.The horned Cretaceous dinosaurs appeared, like the Triceratops and Centrosaurus. The armored Ankylosaurus, duckbilled Parasaurolophus, and large carnivore Tyrannosaurus were a few of the quickly evolving dinosaurs.
