A. The answer is C.
Explanation: it is the only logical answer that describes the difference between the living things.
Q16. The answer is increases between its source and mouth.
A stream's discharge is the amount of water that passes any point at giving time (m³/sec). On the way from the source to the mouth, the amount of water will increase because water is added to the stream from groundwater and tributary streams. That means that more amount of water will pass at the further point from the source suggesting the conclusion that the stream's discharge will increase between its source and mouth.
Q17. The answer is usually consists of fine sand, silt, and clay-sized particles.
A suspended load of a stream is a part of a stream load. The other two parts of the stream load are a bed load and dissolved load. The suspended load consists of particles, usually fine sand, silt, and clay-sized particles, that are carried in the middle part of the stream. However, the size of the particles can depend on the velocity of the stream. That means that stream with higher velocity can carry larger particles.
Q18. The answer is rapids and waterfalls.
V-shaped valleys are deep river valley that at a cross section look like a letter V. They are usually found at the in the upper part of the river. The characteristic of the narrow V-shaped valley is that the stream profile drops rapidly. The common features of this type of V-shaped valley are rapids and waterfalls. The stream profile of the narrow V-shaped valley is the result of cutting the easily eroded bedrock by a stream channel.
Answer:
El pez que cultiva algas.
El cangrejo bailarín.
Explanation:
For a reaction to occur, substrate particles need to collide with each other with enough force (To overcome activation energy), at the right orientation for a successful collision, causing a reaction to occur.
Enzyme catalysts are a type of protein that has a specific 3 dimensional conformation. They have specific reaction sites called active sites. Substrates collides with the enzyme and binds to the active site if it fits to the specific 3 dimensional conformation. This allows bonds to be either formed or broken for reactions to occur.
This process provides an alternative reaction pathway with lower activation energy to enable the rate of reaction to increase.
The answer is; concentration of oxygen and/or total atmospheric pressure is lower at high altitudes
This means that at high altitude, due to the low pressure, every breath has a lower oxygen content than at a lower altitude. This, therefore, necessitates the body to increase the erythrocyte numbers in the blood to maximize the uptake of oxygen from the thinner air.
