The other answers are all a part of the cell theory, but that one is NOT and since the question is asking for the incorrect one, that's the answer. :)
Mars and Moon are the locations from which meteorites would come.
Option (c);
<u>EXPLANATION: </u>
- The meteorites found on Earth look like martian crystal rocks.
- These might be first ejected into space during a collision of an asteroidal object with Moon or Mars and then it got into the Earth orbit because of the force produced during the collision.
- There are around seventy meteorites recognised to have come from the planet Mars till up to the present date.
- There are three types of meteorites such as Martian meteorites and a sample of two lunar meteorites.
- To identify the origin of the meteorite, the scientist tries to identify the type of rock followed by analysing the chemical composition and then try to identify its age.
Answer: 32 chromosomes, they are clones of the parent drone
Explanation:
The production of offspring drones without fertilization means that offspring that are produced are produced by mitosis, which results in daughter cells that are clones of the parent. They have the same amount of chromsomes as the parent drone, which is 32.
Answer:
<u>d. the cells in primary cell cultures do not divide.</u>
A key difference between primary cell cultures and secondary cell lines is that<u> the cells in primary cell cultures do not divide.</u>
<u>hope</u><u> </u><u>it</u><u> </u><u>helped</u><u> </u><u>you</u><u> </u>
Explanation:
<em>The main difference between primary and secondary cell culture is that the primary cell culture contains the cells directly obtained from host tissue, whereas the secondary cell culture contains sub-cultured cells from primary cell culture.</em>
Answer:
GUA and GUG.
Explanation:
If you look at the attached genetic code, the wild-type glutamic acid (Glu) is coded by the codons GAA and GAG.
Valine (Val) can be coded by the codons GUU, GUC, GUA or GUG.
Sickle-cell hemoglobin arises from a single mutation, which causes the translation of Val instead of Glu. The only codons that code for Valine that differ in just one base with the Glu codons are GUA and GUG.
