I had to look for the options and here is my answer: When transcription of a protein-coding gene occurs in a bacterial RNA polymerase, what happens is that, it produces pre-mRNA. Pre-mRNA is also an RNA strand that is not yet matured and it is still to be synthesized.
The answer is taiga.
Taiga is a coniferous forest located in the northern polar subarctic climate zone. What is characteristic for taiga is that winters are very long and very cold. Summers are, on the other hand, short with low temperatures. Many trees in the forest are evergreen conifers with needle-like leaves. <span>Animals have adaptations to seasonal changes by changing their fur or feather color. <span /></span>
Answer:
The correct answer would be - option B. information system.
Explanation:
DNA is the unit of heredity as it contains the genetic code of an organism which is carried all the genetic information and transfer from the parent cell to the daughter cell. It also carries the information required for making all essential proteins in an organism.
So, if an organism did not have DNA, it would be missing the information system which is also responsible for the cell division other than given information.
<em>B. Water; thirst</em>
Explanation:
Water is very vital for survival, even in animals such as dogs. Water is around 90% of blood, so as you can imagine it is very important to consume water regularly to not get dehydrated.
The feeling of thirst is a very important internal stimuli which makes us want to drink water, as our body is fueled on water along with numerous other things. If the water content in Spot's blood gets low, the body will set off a signal for him to get thirsty, which then leads to him getting up to find water.
This is just a way the body continues to work as great as it does, even in dogs! Internal stimuli signals like thirst, hunger, and the feeling of being tired keep our body in check.
