The answer is D. Individual birds with the mutation will be more likely to survive than birds without the mutation
Answer:
The cell interior would experience higher than normal Na+ concentrations and lower than normal K+ concentrations.
Explanation:
Na+/K+ ATPase exists in two forms: Its phosphorylated form has a high affinity for K+ and low affinity for Na+. ATP hydrolysis and phosphorylation of the Na+/K+ pump favor the release of Na+ outside the cell and binding of K+ ions from the outside of the cell. Dephosphorylation of the pump increases its affinity for Na+ and reduces that for K+ ions resulting in the release of K+ ions inside the cells and binding to the Na+ from the cells.
The presence of ATP analog would not allow the pump to obtain its phosphorylated form. Therefore, Na+ ions would not be released outside the cells. This would increase the Na+ concentration inside the cell above the normal. Similarly, the pump would not be able to pick the K+ from the outside of the cell resulting in reduced cellular K+ concentration below the normal range.
I think the correct answer from the choices listed above is option B. Rescuing someone who is in danger is an example of chivalry. Chivalry is a term used to describe the qualities expected for a knight where one is the readiness to help who needs help.
Answer:
B. Earth rotates on its own axis and revolves around the Sun.
Explanation:
The earth moves not only in one way but in two ways. It revolves around its axis and revolves around the Sun.
We do not notice it because we are on Earth and we turn together with it.
When the Earth revolves around its (imagined) axis, we call such a movement a rotation, and when it revolves around the Sun - a revolution.
Answer:
0
Explanation:
This question involves a single gene coding for wool color in sheeps. The allele for white wool (TT) is dominant over the allele for spotted wool (tt). This means that a sheep with an heterozygous genotype (Tt) will be white-wooled.
In this cross, 10 purebred white wool sheep (TT) are crossed with 10 spotted wool sheep (tt). This will give rise to all offsprings with heterozygous genotype: Tt (see attached image for punnet square). Since, white wool (T) is dominant, all the offsprings will have a white wool and none i.e. 0 will have a spotted wool.
