D because the cell membrane transports nutrients and exports waste
Answer:
plasmid
Explanation:
plasmid
The human insulin gene is inserted into each plasmid. The plasmid acts as a vector - it is used to transfer DNA from one organism to another. Bacterial cells are made to take up the genetically modified plasmids.
The purpose of cell cycle is to replicate those parents cell by dividing into cells but maintaining the original cell genome. The cell cycle composes of two phases, the interphase wherein the cells are still growing and preparing for mitosis, the other phase is mitotic phase where in the cells will separate to create daughter cell.
Answer:
The correct answer would be B. segmented worms.
Segmented worms is a common name used for Annelida.
In Latin, Annelida is used to describe "little rings". The body of the organisms of this group is segmented.
It seems like numerous little rings are fused or joined together.
For example, the body of the earthworm is made up of around 100-150 segments.
Answer:
O macromolecule, population, community, ecosystem
Explanation:
Macromolecules are very large molecules composed of atoms, such as complex carbohydrates, fats and proteins (for example, fats are macromolecules mainly composed of C, H, and O atoms). Macromolecules in turn associate to form cellular structures (eg. organelles, cytoskeleton, etc), which subsequently combine to form cells. Individuals are made up of one or more cells (i.e., unicellular and multicellular organisms, respectively). In the next level, populations are groups of individuals of the same species that live within a given area; whereas communities are groups of populations that live in a given area and interact with one another. Finally, an ecosystem can be defined as a group of populations (i.e., a community) and the abiotic factors (i.e., nonliving parts) of their environment that support them (e.g., water, light, radiation, temperature, etc).
