Answer:
D. Nucleus.
Explanation:
A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life. A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Some examples of cell organelles found in all living organisms such as trees, birds, and bacteria include; nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, vesicles, etc.
Proteins on the surface of vesicles determine where the vesicles go.
The nucleus is the cell organelle which provides the instructions for these proteins. It controls all the activities taking place in the cell and the synthesis of proteins.
Answer:
Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio of purine and pyrimidine bases, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.
Answer:
sequences of nitrogenous bases in the cell's DNA
The circulatory system moves the nutrients from the digestive system to all over the body.
Answer:
The hyphae of fungus serve as the main mode of vegetative growth.
Mycelia and hyphae are use to absorb nutrients from other organisms.
Explanation:
Fungi are either unicellular or multicellular organisms that are found in moist, slightly acidic and low oxygen environment. They are heterotrophs and decomposers.
Their cell walls are rigid and are composed of chitin and glucans. They are characterized by long filamentous structure called hypae. The structures of hypae form the mycelia.
