If a somatic human cell is about to divide, then it has 92 chromatids. this is because there are 23 pairs of homologues chromosomes in a cell, one is given by both parents. when a cell divides my mitosis, the pairs separate into 46 chromatids, each one that is replicated which gives you 92 chromatids.
THIS IS known as the PERICARDIUm
The molecule which is the final electron acceptor for electrons from photosystem I is (d) NADP⁺.
Photosystem I is the protein complex involved in the process of photosynthesis. It captures the light energy to mediate the transfer of electrons from a series of electron transporters. It is involved in non-cyclic as well as cyclic photophosphorylation.
NADP⁺ is the Nicotinamide Adenine Dinucleotide Phosphate. It acts as a coenzyme. It is an important constituent in various anabolic reactions like Calvin cycle, lipid and nucleic acid syntheses, etc. The oxidized form of NADP⁺ is NADPH. It is present in organisms of almost all kinds.

Answer:
One Idea was the appreciation that the age of the Earth was much greater than had hitherto for been imagined.
This layer is called the cell wall.
The cell wall is located outside the cell membrane and provides the cells with structural support and protection. It gives cells rigidity and strength, offering protection against mechanical stress.
In most cells, it is flexible, meaning that it will bend rather than hold a fixed shape, but has a lot of tensile strength which is necessary to be able to withstand internal osmotic pressure.
Cell walls are found in plants, bacteria, fungi, algae and some archaea.
