Describe the ways mutations can affect DNA and chromosomes.​
lozanna [386]
Mutations present permanent and heritable changes in the genome. We distinguish gene and chromosome mutations. Mutations in the level of genes are called point mutations because only one to several nucleotides are changed. These processes are known as deletion, insertion, and substitution. Deletion presents a loss of nucleotides which changes DNA sequence. When new nucleotides are embedded in the DNA chain, it is known as insertion. Substitution implies the process where new nucleotides are inserted while the ones that were present in that specific spot in a DNA molecule are deleted.
Mutations can also appear in chromosomes altering their number and structure. There are four types of mutations - deletion, duplication, inversion, and translocation. In deletion, a whole or one part of a chromosome is lost. Duplication presents an extra copy of a whole or one part of a chromosome. In an inversion, parts of a chromosome change order, while in translocation a part of one chromosome detaches and then connects to another.

What would be the advantage(s) to having no chloroplasts in the cells of the spongy mesophyll?
Gwar [14]
Well, first off the spongy mesophyll does have some chloroplasts, however they are located quite far from the surface of the leaf where most of the chloroplasts are. Therefore they don't get much light and don't contribute a lot to photosynthesis in the leaf. So why should the leaf waste the energy in making chloroplasts if there is not enough light to make them all efficient enough at photosynthesis?

How are photosynthesis and cellular respiration related?
Mice21 [21]
The first statement is wrong because photosynthesis occur during day by plants, while respiration happens during day and night which are very related and they can be happened at the same time, in other hand photosynthesis cannot Accor in human cells because animal cells do not have chloroplasts which are using light energy to make glucose ,but in our cells or in animal cells we have mitochondria which break down the energy to make ATP....
for the second statement I'm not sure about that ....
I think that the third statement Is correct, because
the Cellular respiration make carbon dioxide + water + ATP then those would be then used by photosynthesis to make glucose and oxygen .
