Answer:
Structure and function of eukaryotic cell
Eukaryotes have following promint components of cell
1. True nucleus:
The nucleus is surrounded by a true membrane called nucleoplasm. Nucleus contain hereditary materials, DNA which control inheritance. It also contain RNA synthesize in nucleolus.
2. Cell wall:
It is present only in plant cell, and contain cellulose, hemicellulose, lignin, suberin etc. It provides mechanical support to plants.
3. Cell membrane:
It is present both in plants and animal cells. It is made from protein, lipids and carbohydrates. It acts as selective permeable membrane and control the movement of molecules in and out of the cell.
4. Mitochondria and chloroplast:
Chloroplast is present only in plant cell. It contains chlorophyll which aid in photosynthesis and prepare glucose.
Mitochondria is present in all eukaryotic cells.cellular respiration occurs in mitochondria and ATP is formed by the break down of glucose.
5. Endoplasmic reticulum and Golgi apparatus:
Endomembrane system of eukaryotic cell is made from a network of tube and sacks connected together forming endoplasmic reticulum and golgi apparatus independently. Endoplasmic reticulum may have attached ribosomes or not and is involved in protein synthesis, while golgi apparatus help in modification, packaging, and transport of proteins through out the cell.
Lysosomes, cytoskeleton, vacoules, peroxisomes, glyoxisomes and other organelles are also present in eukaryotic cell.
Answer:
You have to finish putting the question
Explanation:
Answer:
May be of the environment they live or genetics.
Explanation:
This naked mole rat species evolved back to an ectothermic life style rather than staying endothermic like all other mammals because of the environment they live or change in the genetic makeup. The main reason for this evolution may be the environmental they lives or through the change in genetic makeup of this naked mole rat species so both factors can contribute in the evolution.
Yes it will.
It happen because of the great ocean conveyor which will moves the water around the globe. As the result of this flow of movement, the water from the bottom of the ocean can move onto the top of the ocean and vice versa
C. The long-term survival of an entire species of organisms
