An earthworm receives support and shape from its fluid-filled cavity. It has Hydroskelton
Explanation:
The muscle of earthworm encloses with two layers of muscle which is circular and longitudinal. There is fluid cavity between digestive part and muscle. it is called coelom and fluid is coelomic fluid. This fluid work as hydrostatic skeleton.
It provides resistance to muscular contraction. It helps the earth worm to applying the force and change the shape. Mostly hydrostatic Skeleton organism has more or less cylindrical. This type of Skeleton found in soft bodied invertebrates.
- Rough Endoplasmic Reticulum.
- Chloroplast.
- Cell wall.
- Mitochondria.
- Vacuole.
- Membrane
- Golgi Apparatus.
- Nucleus
- Nucleolus.
The cell in the diagram is a plant cell because it has chloroplasts and a cell wall.
There are two types of cells animal cells, which are the ones that humans and animals have, and plant cells, which are the ones that plants and trees have. They share some organelles, but they also have some that are specific to each type.
The plant cell parts in the picture are:
- Rough Endoplasmic Reticulum: it is where the ribosomes are. The synthesis of proteins happens there.
- Chloroplast: it is an organelle-specific of plant cells. They are in charge of photosynthesis.
- Cell wall: it is only present in plant cells. It surrounds the membrane.
- Mitochondria: It is the place that generates the energy that the cell needs.
- Vacuole: they are bigger in cell plants than in animal plants. It has many functions, but one is to store water.
- Membrane: it draws the limits of the cell.
- Golgi Apparatus: it is the place where proteins go to be distributed.
- Nucleus: it contains DNA, and it has a membrane around it.
- The nucleolus: is the larger part of the nucleus. It is in contact with the endoplasmic reticulum.
To sum up, the plant cell has a bigger vacuole than the animal cell; it also has chloroplasts and a cell wall, which are not present in the animal cell.

The correct answer is option A, that is, there was no life prior to Phanerozoic.
The Phanerozoic eon refers to the eon of visible life. It began about 541 million years ago. It signifies only one by an eighth of the time since the formation of Earth crust took place.
The Precambrian eon is older, and it extends from 4.6 billion years ago to the Phanerozoic eon. The fossils in the Precambrian eon are rare. It was in the late Precambrian eon that the origination of the first multi-cellular species took place.
