Allele frequencies in a population may change due to four fundamental forces of evolution: Natural Selection, Genetic Drift, Mutations and Gene Flow. Mutations are the ultimate source of new alleles in a gene pool. Two of the most relevant mechanisms of evolutionary change are: Natural Selection and Genetic Drift.
Hello!
A polar molecule is where one of the atoms in a molecule has a slight positive charge, and another has a slight negative charge, due to the unequal sharing of electrons.
Water is one of these molecules - the electrons spend more time around the oxygen atom in the center, and less around the hydrogens, so the hydrogen atoms have a slight positive charge, and the oxygen a slight negative.
Therefore, your answer is B, water has a slight negative and a slight positive charge at opposite poles.
Hope this helps!
Answer:
Cell size at division is determined by the balance between cell growth (the increase in mass or volume) and the timing of cell division. Interestingly, faster growth rates in bacteria and eukaryotes lead to larger cell size. ... In this model cells “add” a constant volume (or mass) between cell divisions
Explanation:
Answer: ATP and NADPH are produced in the light dependent stage
Explanation:
In the light dependent stage of photosynthesis, photoactivation of chlorophyll results in the splitting of water molecules and the transfer of energy to ATP and reduced nicotinamide adenine dinucleotide phosphate (NADPH).
NADPH and ATP are used to carryout the light-independent stage and not just ATP alone as claimed in the publication.
The phrase that needs correction is "ATP is generated in the light reactions "
