Answer: Self-replicating RNA
RNA can do catalytic functions like enzymes. It carries genetic information and replicate itself. It also carries information about vesicles which carries it. RNA is less stable than DNA which confirms that genetic material is evolved from a less stable to highly stable form.
Answer: Option C) water
Explanation:
The factors affecting the distribution of organisms in aquatic biomes include:
- Light penetration: Plants life is limited to the upper layers of the ocean where light cab penetrate and be used to produce food. Thus, very few organisms are found in the ocean deep.
- Waves: the movement of surface water of the oceans, and it's direction affect the placement of organisms as they must have strong anchor or body parts suited for buoyancy
- salinity: not all organisms can survive in water with high salt content. Thus, some live in salty water, and others in fresh water or the mixture.
- Mineral content: the levels of hydrogen ion could make a water bidy alkaline or acidic thus affecting organism that can survive in it
Thus, since water ordinarilly is Universal, it is not an important factor in determining distribution of organisms in aquatic biomes
Answer:
Electron microscope
Explanation:
Electron microscope uses a beam of electrons as energy source. Since the beam has an exceptionally short wavelength, it strikes most objects in its path and increases the resolution of the microscope significantly. Thus it has a higher magnification and resolution.
Answer:
1 is Triton and 2 is retrograde orbit
Answer:
heavier! ( depends what type of metal can)
Explanation:
Rusting has to do something with corrosion and involves oxygen.So basically, when oxygen is added to the system process, this what makes the metal can become heavier.
