Chara 27.3 light years
Tau Ceti 11.9 light years
Zeta Leporis 70.2 light years
Epsilon Reticuli 59.5 light years
The answer is Tau Ceti.
Answer:
Explanation:
Hard-shelled organisms absorbed calcium and carbonate iron and use them in making their hard shells which are calcium carbonate. When these organisms die, there shells are used in the formation of limestone rock. Limestone rocks are a huge store carbon. When acid rain reacts with limestone, these trapped carbon are released to the atmosphere thereby causing an Increase in atmospheric carbon.
Conclusively, the accumulation of limestone rock and subsequent reactions with acids such as acid rain has resulted in an increased atmospheric carbon throughout the years.
Answer:
d. Atrophy of the flexor digiti minimi.
Explanation:
The logical diangosis would be d. Atrophy of the flexor digiti minimi.
Flexor digiti minimi is a hypothenar muscle of that is used when we flex our little toe of the foot.Present at the metacarpophalangeal joint. When the foot is in anatomical position, it is lateral to the abductor digiti minimi. it is homologous to digiti minimi in the hands.
Hence, Atrophy of the flexor digiti minimi is necessary.
Answer:
The missing options are:
A. Spindle fibers have not correctly attached to chromosomes.
B. Damage occurred to DNA when it was being copied in G1.
C. There are not enough nucleotides available to construct new DNA.
D. Proteins necessary for M phase of the cell cycle have not been produced.
The correct option is <u>C.There are not enough nucleotides available to construct new DNA.</u>
Explanation:
During the G1 phase, the cell grows in size since it prepares its organelles and molecule combinations for the next phase of the cell cycle, the S phase. Before the cell transitions to the S phase, it has to pass through a checkpoint that makes sure that there are no mutations, it has grown enough, and has the necessary molecules for the next phase, which is the synthesis of DNA. If there are not enough nucleotides, the cell will not be able to synthesize new DNA in the S phase, so the checkpoint stops the cells from moving to this phase till it has all the necessary things to do it.
