Answer:

<em>The correct option is B) Missense mutation.</em>

Explanation:

A missense mutation can be described as a type of point mutation in which a mutation in a single nucleotide causes the codon to change and form a different type of amino acid. As in the above scenario, we can see that the code CAU coded for the amino acid, Histidine, before a point mutation occurred. After the point mutation, the codon was changed to UAU instead of CAU. UAU codes for the enzyme, tyrosine, instead of histidine.

HACTEHA [7]

Answer: Hypothalamus

Explanation: The interface between the neural and endocrine systems is the hypothalamus, which through the pituitary gland controls the function of the peripheral endocrine glands. The hypothalamus, as a component of both the neural and endocrine systems, monitors the hormones secreted by the endocrine system, i.e. endocrine glands, to provide feedback that goes to the brain for processing. The pituitary gland, as one of the endocrine glands, is also controlled by the hypothalamus, meaning that the hypothalamus controls the secretion of hormones into the blood based on the needs determined by the processed brain data.

Explain how photosynthesis would be affected if there were a shortage of NADP+ in the cells of plants

viktelen [127]

Photosynthesis would stop

NADP+ is important in photosynthesis because they are significant in both light and dark phases of photosynthesis.

Explanation:

IN the light stage, NADP+ is the ultimate electron acceptor as high energy electrons are passed down a protein chain, from the reactive center of photosystems, as their energy is harnessed to create a proton motive force across the lamellae membrane. NADP+ is ultimately reduced to NADPH. Without NADP+, the electron transport chain would cease.

NADPH, on the other hand, is used to reduce carbon dioxide to glucose in the Calvin cycle. NADPH is oxidized to NADP+ which is recycled back to the light stage of photosynthesis.
