In the
evolutionary sense fitness refers to the measure of reproductive success of an
individual or of organisms in general. Those organisms that leave the largest
number of mature offspring are the fittest. Fitness can be achieved through survival
or mortality selection, mating success or sexual selection, and family size or
fecundity selection. Fitness is critical for a species’ survival and is a major
adaptation that all organisms do through a long period of time. <span> </span></span>
The Rules of Protein Structure. The function of a protein is determined by its shape. The shape of a protein is determined by its primary structure (sequence of amino acids). The sequence of amino acids in a protein is determined by the sequence of nucleotides in the gene (DNA) encoding it.
Answer:
Meiosis involves two cell divisions
Explanation:
Mitosis and meiosis are two kinds of cell divisions and one of the main differences between the two is that meiosis goes through <u>2 nuclear divisions</u>.
Meiosis has Meiosis I and Meiosis II division. In Meiosis I, the number of chromosomes in the daughter cells are only half of the parent cells. This is why it is called a reduction division, because the chromosomes will be reduced by half. In Meiosis II, the daughter cells will have the same number of chromosomes as the parent cells, which in this case is the daughter cells of meiosis I.
Answer
Photosynthesis yield sugar in two main steps
1. Light reaction
In this step plant absorb sunlight which cause photolysis of water and excitation of electron. this electron flow through Z-scheme and atlast enter into NADH, the end product of light reaction is ATP and NADH₂.
2. DArk reaction.
In this step ATP and NADH₂ are used as raw materials. it occurs in stroma of chloroplast. here CO₂ is used through Calvin cycle and at the end glucose is prepared.
