Answer: Option 1 is the correct answer
Archaean eon
Explanation:
You are in the Archean Eon era because the it was early in the Archean that life first appeared on Earth. The most two earlier of the formal divisions of Precambrian time (about 4.6 billion to 541 million years ago) and the period when life first formed on Earth It began about 4 billion years ago with the formation of Earth’s crust and enlongated to the begining of the Proterozoic Eon 2.5 billion years ago; the latter is the second formal division of Precambrian time.
In the Archean eon there are unsual landscapes no rocks are preserved from this stage. The earliest terrestrial materials are not rocks but minerals.
Throughout the Archean, oceanic and island arc crust was produced semi-half way.
You cannot breathe because there was no oxygen on the Earth. Oxygen was only present in compounds such as water and chemical reactions change to carbon containing molecules that form simple living cells that does not require oxygen.
The
correct answer is no.
<span>The
development of retinoblastoma occurs as a consequence of mutation of genes RB1
or MYCN. Those mutations occur in the early stages of fetal development and affect
the way in which cells grow and develop within the body. The more common is the
defective RB1 gene that can be inherited from either parent. The expression of
the RB1 allele is autosomal dominant.</span>
Answer:
When we compare the feeding of larvae with royal jelly to raise queen bees with turning off the Dnmt3 gene
It can be said that the latter is more effective in terms of the number of queens that can be produced and the energy expenditure is much lower. Well, keep in mind that bee larvae only become queens when they receive large amounts of royal jelly. A royal jelly protein is what activates the mechanisms to be a queen bee, this jelly machinery the nurse worker bees.
Through genetic manipulation, the Dnmt3 gene can be turned off in any larva to produce a queen bee.
Stable elements are those which have atleast one isotope with no tendency to "decay", i.e., change into anotherelement.
