My best guess would be c because b makes no since we as humans do not have photosynthesis and are considered living organisims, d is also wrong because the brain requires oxygen, and its not a because the brain is made of cells.
So they can handle the tough terrain, like rocks and dirt and gravel and harsh grounds.
They way they have an advantage of actually being able to move places

The average distance is 16,000 km
Converging rate is 10 cm/year
1 km = 100,000 cm
= 16,000 × 100,000/10 cm/year
= 160,000,000 years
It will then take 160 Million years to collide.
Answer:
An anabolic reaction can be described as a reaction in which reactants join to form products. In the process of photosynthesis, carbon dioxide and water molecules join to build up glucose molecules hence, it is an anabolic reaction.
The catabolic reaction can be described as a reaction in which large molecules are broken down into smaller substances. In cellular respiration, glucose is broken down into carbon dioxide and water. Hence, cellular respiration is a catabolic reaction.
The equations of photosynthesis and cellular respiration are exactly opposite to one another. Hence, holding a connection. The products of photosynthesis are the reactants of cellular respiration and vice versa.
Answer:
The order must be K2→K1, since the permanently active K1 allele (K1a) is able to propagate the signal onward even when its upstream activator K2 is inactive (K2i). The reverse order would have resulted in a failure to signal (K1a→K2i), since the permanently active K1a kinase would be attempting to activate a dead K2i kinase.
Explanation:
- You characterize a double mutant cell that contains K2 with type I mutation and K1 with type II
mutation.
- You observe that the response is seen even when no extracellular signal is provided.
- In the normal pathway, i f K1 activat es K2, we expect t his combinat ion of two m utants to show no response with or without ext racell ular signal. This is because no matt er how active K1 i s, it would be unable to act ivate a mutant K2 that i s an activit y defi cient. If we reverse the order, K2 activating K1, the above observati on is valid. Therefore, in the normal signaling pathway, K2 activates K1.
