Answer:
Genes and alleles assort independently during gamete formation. The possible gametes for the following will be: AB, aB, Ab, ab. The alleles will assort independently for each of the genes, hence there are equal chances for a gamete to carry the AB, aB, Ab or ab genes.
As Mendel's studies explained that alleles assort independently into gametes hence there are equal chances for a gamete to carry all the variability.
Answer:
The answer is A.
Explanation:
During logarithmic growth phase bacteria grows exponentially doubling every x minutes (x depends on the species). In this question doubling time/generation time is every 15 minutes and log phase takes 5 hours, which equals to the 300 minutes. During 300 minutes bacteria doubles 20 times (300/15 = 20) which equals 2^20. Bacteria culture has been started with 1000 bacterial cells so it must be added to the calculation therefore right answer is: 1000 X 2^20.
The opening of the stomata is thought to have or involve
with an increase in regards with the osmotic concentration in terms of the
guard cells. The guard cells are the ones surrounding the stomata in which when
they are pressured, they are likely to grow small or big.
According to the second law of thermodynamics, energy is never 100% efficient because some of the energy disperses as heat.
Answer: Option (d) is the correct answer.
Explanation:
Nucleus of an atom consists of protons and neutrons. Protons are positively charged and neutrons have no charge. So, due to the like charges of protons there occurs electrostatic force of repulsion inside the nucleus of the atom.
But due to similar number of neutrons and protons a force that is able to bind both of them together is known as strong nuclear binding energy.
This force is strong enough that it is able to overcome electrostatic force of repulsion. But when there is great difference in the number of protons and neutrons then binding force is not strong enough.
Hence, the atom becomes unstable and undergoes radioactive decay. So, this means weak forces are responsible for radioactive decay.
Thus, we can conclude that the statement which best describes Yanni’s error is that the strong force is responsible for radioactive decay.
