Gravity , Explosion
<u>Explanation:</u>
Nebulae are made of dust and gases—mostly hydrogen and helium. The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger.
Eventually, the clump of dust and gas gets so big that it collapses from its own gravity. The collapse causes the material at the center of the cloud to heat up-and this hot core is the beginning of a star.
The correct answer is:
A. begin with the breakdown of glucose in glycolysis.
Explanation:
They both begin with a sequence of reactions known as glycolysis, which breaks glucose particles into smaller pyruvate molecules. They are also related in that through both processes, ATP is generated for the cell to use. Glycolysis is the metabolic pathway that transforms glucose C6H12O6, into pyruvate, CH3COCOO− + H+. The free energy delivered in this process is applied to form the high-energy molecules ATP and NADH .
Answer:
The correct answer will be option-accurate and complete DNA replication.
Explanation:
The cell cycle of a cell is controlled by the internal checkpoints where the cell cycle halts until the favourable conditions appear. These checkpoints are G1 checkpoint, G2 checkpoint and M checkpoint.
The G2 checkpoint asses that the DNA replication has been completed, all the chromosomes have been replicated and the replicated DNA is not damaged. The cell cycle stops if the replicated DNA is found damaged.
Thus, option-accurate and complete DNA is the correct answer.
Answer:
C
Explanation:
because it is a polymer of amino acid so it will be a protein
hope it make sense:)
Answer:
The correct answer is C) There is a larger variety of MHC proteins that can be expressed on the cell surfaces of their immune cells, providing a wider opportunity to recognize and attack pathogens.
