Answer: the structure of an atom: At the center of the atom, there is a very small region called the nucleus. This area makes up most of the mass of the atom.
The area around the nucleus is called the electron cloud. This area makes up the majority of the volume of the atom. The electron cloud is mostly empty space.
Explanation: Hope this helps :)
Answer:
Centrioles is only found in animal cells
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 .
can I get brainlist pls?
Answer:
In eukaryotes, it is well known that polyadenylation is required to produce the mature messenger RNA (mRNA) molecule and it provides stability to the mRNA during translation initiation. In prokaryotic organisms, polyadenylation is required for the degradation of the mRNA in a mechanism that involves three steps: endonucleolytic cleavage, polyadenylation and exonucleolytic degradation. Moreover, it is also important to note that no evidence of polyadenylation has bee reported in some prokaryotes including the halophilic bacteria Haloferax volcanic (Slomovic et al. 2005).
