The number one difference among those sorts of organisms is that eukaryotic cells have a membrane-certain nucleus and prokaryotic cells do not. The nucleus is wherein eukaryotes save their genetic information.
Prokaryotic cells lack a nucleus surrounded with the aid of using a complicated nuclear membrane and typically have a single, round chromosome positioned in a nucleoid.
Eukaryotic cells have a nucleus surrounded with the aid of using a complicated nuclear membrane that includes multiple, rod-fashioned chromosomes.DNA is loosely contained with inside the nucleoid region, eukaryotic cells own a nucleus, that's surrounded through a complicated nuclear membrane that homes the DNA genome.

B.obtener energia, reproducirise y eliminar desechos
Answer:
D) The area was on land.
Explanation:
We can tell that this is the answer because of the process of elimination.
- It is not A or C, because there is not enough information given to us to determine whether the area was hot or cold.
- It is not B, because ferns do not grow in the ocean. (Unless it a specific type of water fern that have not heard about... but this is <u>highly unlikely</u>, so don't worry.)
- This leaves us with: D) The area was on land. This is the correct answer because ferns do grow on land, and a sedimetary rock containing a fern fossil is much more likely to be found on land than on the ocean floor.
Hope I could help!

Answer:
True. You can get vitamin A as "preformed vitamin A" which is already active and/or you can get vitamin A as carotenoids which the body can turn into active vitamin A.
Explanation:
There are two different types of vitamin A that can be obtained from food:
1. Preformed vitamin A, which is already active, is found in animal products such as beef, fish, poultry and dairy products.
2. Provitamin A, which is the inactive form, is found in plant-based foods, such as fruits and vegetables. The most common type of provitamin A is β-carotene, which is a carotenoid that the body can turn into active vitamin A via an enzyme named β-carotene 15,15'-monooxygenase.
Characteristics of Endocytosis:
* use energy
* takes substances into a cell
* moves substances in vesicles
Characteristics of Exocytosis:
*use energy
*releases substances outside a cell
*moves substances in vesicles.
Both use energy and move substances in vesicles.
