Answer:

A scenario where a cell may be needed to perform a form of endocytosis is when transporting large molecules. A scenario where a cell may be needed to perform a form of exocytosis is when releasing the large molecule from the cell.

In exocytosis,cells release material such as proteins like enzymes from within the cell into the extracellular space. Endocytosis is where a  cell transports molecules such as proteins <span>into the cell. The complimentary and twined processes can be used for the transport of proteins as an example.</span>

The crossing of a hybrid and a dominant purebred will always result in offspring which are what?
inn [45]

Answer:

Dominant

Explanation:

A hybrid trait is also known as heterozygous, which is the combination of the dominant and recessive alleles of a gene. On the other hand, a purebred is combination of the same two dominant alleles or the same two recessive alleles. For example, in the gene coding for height, allele for tallness (T) is dominant over the allele for shortness (t).

A purebred for this trait will either be "TT" or "tt" while a heterozygous or hybrid will be Tt. Hence, according to this question, crossing of a hybrid (Tt) and a dominant purebred (TT) will always result in offspring which are DOMINANT (see attached image).

Rina8888 [55]

Options:

A. The enzyme lactase will speed up the breakdown of lactose in the small intestines.

B. Reactions that involve enzymes require more energy than reactions without enzymes.

C. The enzyme lactase will slow down the breakdown of lactose in the small intestines.

D. Lactase will require more energy to break down lactose, and less energy is required if it is not present.

Answer:

A. The enzyme lactase will speed up the breakdown of lactose in the small intestines.

Explanation:

A. The enzyme lactase will speed up the breakdown of lactose in the small intestines. - this is true. Lactase is an enzyme that catalyses the breakdown of lactose.  This means it greatly reduces the activation energy required for the breakdown of lactose, and the reaction will happen quicker.

B. Reactions that involve enzymes require more energy than reactions without enzymes. This is false. Reactions that involve enzymes require less energy that reactions without

C. The enzyme lactase will slow down the breakdown of lactose in the small intestines. This is false. It will speed it up

D. Lactase will require more energy to break down lactose, and less energy is required if it is not present.  This is false, more energy is required if it is not present

Which ingredients are needed to transform NADP+ to NADPH?
Gnesinka [82]

Answer: Two electrons and a hydrogen ion

Explanation: The light reactions use solar power to reduce NADP+ to NADPH by adding a pair of electrons along with a hydrogen nucleus, or H The light reactions also generate ATP by powering the addition of a phosphate group to ADP, a process called photophosphorylation.
