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
Answer:
d option eukarya
Explanation:
Organisms belonging to the plant kingdom are eukaryotic and multicellular organisms. They have a distinct cell wall made of cellulose. Cells are organised into true plant tissues. Plants contain plastids and photosynthetic pigments such as chlorophyll.
Passive transport<span> is a kind of </span>transport<span> by which ions or molecules move along a concentration gradient, which </span>means<span> movement from an area of higher concentration to an area of lower concentration. Examples of passive </span>transport<span>include diffusion, filtration, and osmosis.</span>
True, Eukarya is the only domain with multicellular organisms
I think the answer is Ancestors
