Answer: Cells have specific jobs they have to do, like for example, reproduction, cells help in the reproduction of organisms. Energy metabolism, some cells help with nutrients and oxygen. Regeneration, if you get a cut or a scrape, some cells help to heal that wound. And information transfer, this is when we get information in our brain.
Hope this helps!
Answer;
D. redwood tree forests.
Explanations;
Gymnosperms are seed-bearing vascular plants including, conifers, cycads, ginkgo, in which the ovules or seeds are not enclosed in an ovary.
In gymnosperms the cone is the female reproductive part and the pollen is the male reproductive part.
Red wood trees are examples of gymnosperms and are important in maintaining the balance of carbon dioxide in the atmosphere like other green plants.
1. hydrogen atoms crash together
Hydrogen atoms (or protons) fuse within the Sun core and fall apart.
2. helium atoms are formed
Helium atom is a product of the proton-proton fusion and this process occurs through a series of steps.
3. an enormous amount of energy is released
The transformation that occurs after the fusion results in a release of huge amount of energy that keeps the sun hot. Energy is radiated out from the core of the Sun
4. energy travels to Earth in the form of light energy and heat
This energy is called The Solar energy to the Earth because it hits the surface of the Earth itself.
5. plants will use energy from the sun to make their own food
Plants are phototrophic organisms that transform the light energy into usable energy for their metabolism.
Answer:
B
Explanation:
It would not be D because D is the location of a common ancestor, AKA an animal that does not haver jaws or bones. It would not be C because the question states that the fish has jaws, and C does not have jaws since the arrow does not point to that. It would not be A because the question states the fish has "NO TRUE BONES", meaning that there are no bones present. And in A, there is the bones arrow pointing to it, meaning that A has bones since that trait is on the same horizontal line as A. Only leaving us with option B left, since it came from an ancestor with jaws but not from an ancestor with bones. Sorry, I'm not the best with explaining but hopefully that makes sense why it is B, it's like a family tree, you just have to follow it carefully :) I hope that helps
Answer:
As the cell ages the volume of cytoplasm increases, enzymes that synthesize DNA move from the nucleus to the cytoplasm, and there is a gradual build up of lipofuscin. While it is unclear how this directly affects the cell, it is known that once the DNA migrates from the nucleus it is unable to synthesizes enzymes.
Explanation:
there
