This question is incomplete. The options are:
a. Oligocene b. Eocenec. Miocene<span>d. Pleistocene
</span>Option b is correct. This relates to the Paleocene-Eocene Thermal Maximum (PETM) which occured around 56 million years ago and was similar to modern-day climate change. Warming of more than 5 degrees Celcius occured over<span> 15-20 thousand years because of input of more than 2000 gigatons of carbon into the atmosphere. The PETM resulted in mass deep ocean extinctions and mass terrestrial and shallow ocean diversification.</span>
Chromatin is a simpler for of a chromosome. For example, in mitosis (somatic cells dividing) chromatin is in the nucleus, however when it condenses, it forms chromosomes.
Answer:
Explanation:
I would say that your answer would be A.) seeds. Plants don't even have reproductive organs, so that answer would be a definite no. Pollen and nectar comes from both trees and flowers, not fruit. So, that would make your answer seeds.
Answer:
DNA polymerase makes a molecule of RNA from a DNA template
Explanation:
DNA polymerase is an enzyme involved in the process of DNA replication. DNA replication replicates or synthesizes a new DNA replicate from the parental DNA.
The enzymes mentioned in the question perform a specified function which is matched with their description except for DNA polymerase as this enzyme is responsible for adding nucleotides to the synthesizing strand from the template strand f DNA.
Thus, the selected option is correct.
Answer:
When the virus enters a living cell (a human cell, if the virus infects humans, or a bacterial cell, if the virus infects bacteria) it reprograms that cell and turns the cell into a virus factory. Adaptive Immunity: All organisms have different types of immunity to protect themselves against infection.
While both can cause disease, viruses are not living organisms, whereas bacteria are. Viruses are only "active" within host cells which they need to reproduce, while bacteria are single-celled organisms that produce their own energy and can reproduce on their own.
As you might think, bacterial infections are caused by bacteria, and viral infections are caused by viruses. Perhaps the most important distinction between bacteria and viruses is that antibiotic drugs usually kill bacteria, but they aren't effective against viruses.
Some bacteria help to digest food, destroy disease-causing cells, and give the body needed vitamins. Bacteria are also used in making healthy foods like yogurt and cheese. But infectious bacteria can make you ill. They reproduce quickly in your body.
