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.
2) The concentration of O2 will increase inside the cell.
The cell will want to reach equilibrium, meaning that there should be an equal number of oxygen inside and outside the cell. In the picture, more oxygen is shown outside the cell than inside so oxygen will flow into the cell until it has reached equilibrium. Therefore, the concentration of O2 will increase in the cell.

1. grow more
2.do organisms make plants grow faster
3. what type of organism supports the plant the best
Answer:
The endocrine system is a chemical messaging network. Endocrine glands secrete hormones, which are carried by the circulatory system throughout the body. The primary endocrine glands are the pituitary, hypothalamus, pineal gland, thyroid, parathyroid, adrenal, pancreas, ovary, and testis. Hormones maintain homeostasis in the body.

Answer:
The correct answer is option b. "The receptor potential is carried by neuroglia".
Explanation:
Neuroglia is a term used to describe a class of cells which main function is to support the neurons. The term neuroglia include astrocytes, ependymal cells and oligodendrocyte. It is false to affirm that the receptor potential is carried by neuroglia, the receptor potential is carried out by the neurons.
