Answer:
B. Sodium ions directly enter the cells, indicating the signal is transduced by an ion channel.
D. Sweet utilizes the GPCR signaling pathway, activating phospholipase C.
Explanation:
The taste received by the taste buds is processed through different channels
a) The Sweet, bitter, and umami tastes are transduced by the GPCR (G-protein-coupled receptors) signaling pathway
b) Sour taste reaches the taste bud through the acidification of acid-sensitive membrane proteins with in the taste cell
c) The epithelial sodium channels in the renal tissues directly takes up the salty taste
Hence, option B and D are correct

Explanation:
Selective breeding -
It is the method of selection , where the human develops the new organism having some characteristics which they desire , is known as selective breeding .
In this case , the humans select two parents to mate in order to produce the offspring with the desirable traits .
hence ,
Humans are responsible of the process of selective breeding .
Answer:
Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP. Overall, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water.
