Answer:
During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.
Explanation:
Layer 8 is older than layer 1
For full activation of a cyclin-CDK complex, an enzyme called CDK-activating kinase must phosphorylate an amino acid near the CDK active site.
CDK-activating kinase (CAK) actuates the cyclin-CDK complex by phosphorylation of an amino acid i.e. threonine residue 160 near the CDK active site.
CAK is a member of the CDK family and serves as a positive regulator of CDK1, CDK2, CDK4, as well as CDK6.
CDK activation needs two steps. Primarily, the cyclin should attach to the CDK and secondly, CAK should phosphorylate the cyclin-CDK complex on the threonine residue 160, that is situated in the CDK activation section.

Answer:
Organisms in the surviving population will be genetically superior, which will strengthen the population
Explanation
Mutation are the fundamental forces of evolution,as they fuel the variability in the population
Ans.
The Sanger sequencing or chain-termination method for sequencing involves use of ddNTPs (dideoxyribonucleotide triphosphates) to identify the sequence of nucleotides in a DNA segment. The ddNTPs are nucleotide derivatives that lack both the 2'- and 3'-hydroxyl group, hence called dideoxyribonucleotides. When a ddNTP is added to a growing chain of DNA, absence of 3'-hydroxyl group leads to termination of growing chain as this ddNTP cannot make phosphodiester bond with a NTP and DNA sequence can be identified.
Thus, the correct answer is option C).
