40. I remember this by knowing that haploid is like half and diploid is like double
We know that reate constant (-Ea/RT)
K = Ae^(-Ea/RT)
A = frequency factor
Ea = activation energy
R = constant
T = temperature
Let us take two rate constants
<span>K1 = Ae^(Ea1/RT) </span>
K2 = Ae^-(Ea2/RT)
K2 = K1/H
<span>H = e^ (Ea2/RT - Ea1/RT)</span>
1.386 = 1/RT (Ea2 – HG Kj/mol)
<span>Substituting everything to the equation, we get 3.43 kJ/mol</span>
Answer:
Explanation:
. Natural selection is a pressure that causes groups of organisms to change over time. Animals inherit their genetics from their parents or ancestors, and the environment is constantly changing. So, no organism is perfectly adapted to its environment.
The three evidence that support the existence of plants on Antarctica are:
- Climate;
- Pollen;
- Herbivorous animals;
Apart from the plant fossils found on Antarctica, there are few other evidence that suggest that plants existed in the past on the now frozen continent. Some of those evidence for the existence of plants on Antarctica are the pollen found in the rocks and fossils of organisms, the climate records, as well as the herbivorous animals.
The pollen is only released by the plants, thus that is a sure indicator that plants were occupying this part of the world.
The climate records on Antarctica that can be seen in the rock layers, suggest that for most of its existence, Antarctica had a warm and wet climate, which is perfect conditions for the plants to thrive.
The herbivorous animals are feeding themselves on plant material, so since there's fossils of herbivores in Antarctica, it for sure is an evidence that there were plants existing in order for them to feed and be able to live in there.
Answer:
RNA Analysis
Explanation:
the test shows that in archaea, the RNA polymerase is complex and contains more subunits, than the RNA polymerase in bacteria.
