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
The commas (,) I used separate the 2 processes
No,yes
Yes,no
Chloroplasts, mitochondrion
Yes, no
Carbon dioxide +water(in the presence of sunlight energy),
Oxygen and glucose
Oxygen +glucose +energy, carbon dioxide + water
Carbon dioxide is used up(photosynthesis), carbon dioxide is produced(respiration)
Light energy, glucose
Released, captured
PHOTOSYNTHESIS
Light energy
CO2+ H2O (——————-> O2+C6H12O6
RESPIRATION
O2+C6H12O6——————> CO2+H2O
The answer is D, sweating.
Homeostasis is where the body uses some mechanisms to maintain a optimum condition for the body to function. These conditions may include body temperature, blood glucose level etc.
Sweating is a mechanism that can help maintain the body temperature. During hot conditions, the sweat glands under the skin surface may produce sweat, which is then released to the skin surface. When the sweat is on the skin surface, they evaporate. During evaporation, heat energy is brought away from the skin as the sweat molecules that have a higher kinetic energy (=temperature) escaped from the sweat drop. The average temperature of the sweat is reduced.
Eventually, the temperature of the body is decreased and this help maintain the suitable temperature for the body to function.
Therefore, your answer is D, sweating.
