True both the ring of fire and island arcs are places with a lot of volcanoes
Answer:
In explanation.
Explanation:
Relationship between photosynthesis and cellular respiration.
-Both involve in the production of energy
-Both involve the exchange of gases
-Both the process takes place in cell organelle which was considered as endosymbiotic organism. They are chloroplast and Mitochondria, Photosynthesis takes place in the Chloroplast whereas respiration takes place in mitochondria.
-At critical condition both have an alternate pathway.
Extra: differences between photosynthesis and cellular respiration.
-Photosynthesis takes place in the chloroplast, whereas respiration takes place in mitochondria.
-Photosynthesis involves the production of carbohydrate and respiration involve breaking of carbohydrate.
-Photosynthesis occurs only during the presence of sunlight whereas respiration occurs all the time.
-In the photosynthesis process Oxygen is released whereas in respiration Oxygen is utilized.
Positive selection tests to see if the TCR of a T-lymphocyte can recognize and bind to an MHC molecule.
<h3>What is a T-lymphocyte?</h3>
A T-lymphocyte is a special type of immune cell that is generated inside the bone marrow.
The T-cell receptor (abbreviated as TCR) is a protein located on these immune T lymphocytes.
In conclusion, Positive selection identifies if the TCR of a T-lymphocyte can recognize and bind to an MHC molecule.

Answer:
Because the offspring of a male and female are always going to be xx, xx, xy, or xy.
Explanation:
Remember that men have different reproductive chromesomes than women. Women have 2 x chromesomes(xx) while men have 1 x and 1 y(xy). These are given down to their offspring.
So we can write the this out in a punnet square as(link down below).
After you see the visual, you will find that the genotypes are xx, xx, xy, xy.
As I said above, women have sex chromesomes xx, while men have sex chromesomes xy. When you match the genotypes on the punnet square with the ones we know from men and women, we find that two of them match with men and two match with female.
So with this, we can conclude that 2/4 of offspring will always be male and 2 will be female. And as you well know 2/4 is 1/2 which is 50%.
