They are all rock with different size and shapes and are located in different areas possibly in the same areas but they all have there own unique textures from the photographs and 3 of them look like maybe a fossil of some type of when the dinosaurs where still around and the rocks on the top left corner look smooth and are a small type of igneous rocks. That have been soothed over the years.
<h2>Active & Passive transport</h2>
Explanation:
- Active transport is where a chemical reaction using ATP moves things in/out of the cell through transport proteins within the cell wall. It uses a concentration gradient to trigger the reaction (it goes against the concentration gradient in active transport)
- Molecules move against a concentration gradient ( low concentration ―→ high concentration)
- Cellular energy (ATP) is required
- Passive transport also uses a concentration gradient by diffusion (hydrophobic or very small polar molecules) and facilitated diffusion via carrier proteins and channels
- Molecules move along the concentration gradient (high concentration ―→ low concentration)
- No cellular energy is required
Answer:
archaeabacteria ( context clues can often give the answer :)
Answer:
A) Leaf cell
Explanation:
Plant cells are surrounded by cell walls, made of cellulose
The answer is this: the RNA is only translated into a single long polypeptides, which is then cleaved into shorter ones.
