Answer:
B. Cartilaginous fish
Explanation:
Sharks have a cartilaginous skeleton. Cartilage is less dense than bone which allows sharks to move quickly through the water without using too much energy.
Answer:
A. produce larger materials from the collision of smaller materials
Explanation:
The outcome of nuclear fusion reaction is that it produces larger materials from the collision of smaller materials.
- Nuclear fusion is the combination of small atomic nuclei into larger ones with the release of a large amount of energy.
- The energy released provides the needed temperature for another set of atoms to fuse.
- This process in turn yields a bulkier material accompanied with the release of a lot of energy.
Answer:
The growth factor receptors have a kinase domain while the Cytokines receptors do not contain a kinase domain as part of their structure.
Explanation:
The two are signaling molecules that control cell activities in some manners, such paracrine, endocrine and autocrine manners.
The receptor kinase domain can be specific for substrate sites in which phosphorylation occurs.
Answer:
D. It is the general term used to describe the amount of water vapor in the air
Explanation:
It's been a while since I've taken meteorology (2 years), but I think this is the correct answer because humidity in general refers to the amount of water vapor in the air and as we are discussing relative humidity, it cannot indicate the actual quantity of water vapor in the air (thus ruling out B). Therefore, D makes the most sense. I believe C refers to adiabatic cooling.
A student looking through a light microscope saw this cell in cytokinesis. This cell is most likely from a plant.
