Answer:
b?
Explanation:
all of them are a community because a community coonsists of different types of organisms working together in an envoirment
1. DNA replication produces two identical DNA molecules, called sister chromatids, which separate during mitosis.
2. After chromosomes condense, the centromeres is the region where the identical DNA molecules are most tightly attached to each other.
3. During mitosis, microtubules attach to chromosomes at the Kinetochores.
4. In dividing cells, most of the cell's growth occurs during Interphase
5. The mitotic spindle is a cell structure consisting of microtubules, which forms during early mitosis and plays a role in cell division.
6. During interphase, most of the nucleus is filled with a complex of DNA and protein in a dispersed form called ,chromatin.
7. In most eukaryotes, division of the nucleus is followed by cytokinesis, when the rest of the cell divides.
8. The centrosomes are the organizing centers for microtubules involved in separating chromosomes during mitosis.
Answer:
Fat, starch, sugars and protein.
Explanation:
Enzymes break these biomacromolecule bcoz cells get energy by breaking them.
<span>Most reflex arcs involve only three neurons. The stimulus, such as a needle stick, stimulates the pain receptors of the skin, which initiate an impulse in a sensory neuron. This travels to the spinal cord where it passes, by means of a synapse, to a connecting neuron called the relay neuron situated in the spinal cord.</span>
