Answer: Cell membrane
Explanation:
The cell membrane has the ability to transfer the molecules from the exterior of the cell to the interior of the cell.
The cell membrane is semi permeable which means only selected molecules will pass through the cell membrane.
The molecules and substances that are synthesized inside the cell needs to be transported from inside to outside via cell membrane.
Answer:
The correct answer will be option E.
Explanation:
The features given in the question are the characteristics features of the group of bacteria belonging to Cyanobacteria.
These Cyanobacteria are the prokaryotes which are capable of synthesizing the food through a process called photosynthesis. These bacteria use sunlight as their energy, use water and air to synthesize food. They under anaerobic condition synthesize the nitrogen in special structures called heterocyst, a characteristic feature of cyanobacteria.
Thus, the features given in the question are:
1. contain photosystems to carry out photosynthesis.
2. producing oxygen
4. contain phycobilins
6. Hetrocysts: nitrogen-fixing structures.
7. The ancestor of plant chloroplasts.
Thus, option E is the correct answer.
Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy between physical systems.
Reticulum is the only one I know of that contain lysosmes.
Answer:
C) DNA produces messenger RNA, also called mRNA.
Explanation:
During transcription DNA is used as a template to make RNA. RNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. Translation reads the genetic code in mRNA and makes a protein.
