Answer:
Telophase can be described as the phase in which there are complete haploid set of chromosomes. The chromosomes have two sister chromatids. A cleavage furrow is formed from the centre of the cell which divides the cell into two parts. Telophase is the final stage of the process of division of a cell.
Cytokinesis can be described as a process by which the cytoplasm between the two new daughter cells separate.
Answer:
Lava flows block a river.
Explanation:
Lava flows block a river. Streams flow into shallow areas. Groundwater feeds into low-lying areas. Grassy wetlands get covered by a stream.
<span>Point mutations are of two types: Substitutions of bases that are the change of one base of DNA by another. And Transitions that are replaced on a pyrrhic basis by another pyrrhic or a pyrimidine by another pyrimidine. Transversions: substitution of a pyrrhic base by another pyrimidine or vice versa. These mutations are negative because they affect only one of the nucleotides, and therefore, only one triplet of bases are affected. When the mutation does not affect the individual it is a silent mutation. Chromosomal mutations Changes in the structure of the diploid chromosomes, where one of the chromosomes has a mutation, will have another normal. They can hinder the process of meiosis in the carrier since it hinders the correct pairing of the homologous chromosomes. It would produce an unfeasible offspring or with mutations.</span>
Answer:
Starch present in A and C, starch not present in B.
Explanation:
Photosynthesis is the process by which plants synthesise sugar.
This process requires light energy, carbon dioxide, and water, and produces sugar and oxygen. This sugar can be turned into starch.
In leaf B, the chemical that absorbs carbon dioxide would mean that there is none in the air for the plant to take in and use for photosynthesis, so it would not make sugar which can be converted to starch.
This is in contrast to C and A, where there is carbon dioxide present in the bag that can be used in photosynthesis.
Answer:
The reactants for photosynthesis are light energy, water, carbon dioxide, and chlorophyll.
