“In the light-dependent reactions, energy absorbed by sunlight is stored by two types of energy-carrier molecules: ATP and NADPH. The energy that these molecules carry is stored in a bond that holds a single atom to the molecule. For ATP, it is a phosphate atom, and for NADPH, it is a hydrogen atom.”
Functions of blood:
1. Blood carries oxygen from and carbon dioxide to lungs, nutrients from guts, urea from the liver.
2. It contains anti-bodies, hormones, haemoglobin and many other substances.
3. It distributes heat around the body.
The true difference between the two cells is prokaryotes
a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles. On the other hand, Eukaryotes are organisms consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. Eukaryotes include all living organisms other than the eubacteria and archaebacteria.
The amount of genetic variation in a population
Because it creates the same amount of tension for small animals as skin would. That is why some small animals can be on water without sinking. That is surface tension.
