Explanation:
An organism can be homozygous dominant if it carries two copies of the same dominant allele, or homozygous recessive if it carries two copies of the same recessive allele. Heterozygous means that an organism has two different alleles of a gene.
A homozygous recessive allele combination contains two recessive alleles and expresses the recessive phenotype. For example, the gene for seed shape in pea plants exists in two forms, one form (or allele) for round seed shape (R) and the other for wrinkled seed shape (r)

Attached is the exercise. I found the full scheme on the internet.
For the position "a" the correct label is the pink label with glucose concentration low. This type of cotransportation transports two solutes in the same direction, being one in favour of its gradient, and another one against its gradient. In this case the one that's in favour of its gradient is the Na+, so the glucose is in low concentration outside the cell.
For the position "b" the correct label is the one with the glucose and Na+ entering the cell. This is cotransport, done by the glucose-sodium cotransporter.
For the position "c" the correct label is the pink label with glucose concentration high. This type of cotransportation transports two solutes in the same direction, being one in favour of its gradient, and another one against its gradient. In this case the one that's in favour of its gradient is the Na+, so the glucose is in high concentration inside the cell.
For sentence "1." the correct term is "down". Because the Na+ concentration is higher on the outside of the cell, the Na+ moves down its electrochemical gradient.
For sentence "2." the correct term is "against" for the reasons explained above.
Answer:
The Hydrogen Fusion Process In the basic Hydrogen fusion cycle, four Hydrogen nuclei (protons) come together to make a Helium nucleus. This is the simple version of the story. There are actually electrons, neutrinos and photons involved that make the fusion of Hydrogen into Helium possible.
