<span>linnaen classification was 2 kingdom classification,named plantae and animalia, on the basis of nutrition w.h.whittaker included 5 kingdom classification monera,protista,fungi,plantae,animalia.
so option b)plant and animal kingdom is right,
actually linnaeus put all protists,monerans,and plants in one kingdom plantae,though they have different cell structure,and mode of nutrition.</span>
I think it’s B. Hunting and gathering !
⭐️ A number of forces can cause gene mutations, such as smoking, radiation, viruses, cancer-causing chemicals (carcinogens), obesity, hormones, chronic inflammation and a lack of exercise.⭐️
Polyribosomes are groups of ribosomes linearly arranged, associated with mRNA, and producing several copies of proteins. The coupling of processes shown in the image can not be found in eukaryotic cells.
<h3>
What is a polyribosome?</h3>
A polyribosome is a group of single ribosomes associated with an mRNA molecule and producing simultaneous translation events of the same protein.
Polyribosomes can be found in both prokaryotic and eukaryotic cells. However, translation occurs at different moments and places in these cells.
⇒ In a prokaryotic cell
Polyribosomes can act before transcriptional termination occurs.
While transcription is still happening, ribosomes can produce many polypeptide copies.
This is because
- both transcription and translation occur in the cytoplasm simultaneously.
- transcription and translation directions are 5' to 3'.
- mRNA does not need to be modified after transcription.
⇒ In eukaryotic cells
Polyribosomes are found in the cytoplasm but only when
- the transcription process is over,
- the mRNA molecule is already modified and left the nucleus.
Since transcription occurs in the nucleus and translation in the cytoplasm, they can not be simultaneous.
According to this information, the coupling of processes shown in the image can not be found in eukaryotic cells.

Answer: Increased reproductive success of individuals with the ability to survive in a variety of water temperatures
Explanation: Natural selection establishes that the conditions of an environment favor or hinder (select) the reproduction of organisms according to their characteristics. Natural selection was proposed by Darwin as a means to explain biological evolution.
The trait subject to selection must be inheritable.
There must be variability of the trait among the individuals of a population.
The variability of the trait must give rise to differences in the survival or success of the player, making certain characteristics of the new appearance can be extended in the population.
The accumulation of these changes over generations would produce all evolutionary phenomena.
