Answer:
1)Ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom.
2) The atom that loses the electrons becomes a positively charged ion (cation), while the one that gains them becomes a negatively charged ion
3)onic bonds are important because they allow the synthesis of specific organic compounds. Scientists can manipulate ionic properties and these interactions in order to form desired products. Covalent bonds are especially important since most carbon molecules interact primarily through covalent bonding.
Explanation:
Internal regulators allow the cell cycle to proceed only when certain processes have happened inside the cell. ... Cancer cells do not respond to the signals that regulate the growth of most cells. As a result, they divide uncontrollably and form masses of cells called tumors that can damage the surrounding tissues.
Answer: c. binary fission
Explanation:
Binary fission or bipartition is a way of asexual reproduction that is carried out in archaea and bacteria. It consists of the duplication of DNA, followed by the division of the cytoplasm (process called cytokinesis), giving rise to two daughter cells.

If a student made a model of an onion skin cell using a microscopic magnification scale of 500:1 and the length of the modeled cell is 15 cm, the real cell's length would be 0.03 cm.
The scale is 500:1. This means that the dimension of the real cell without being magnified under the microscope would be 1/500.
Thus, if the length of the cell under the microscope is 15 cm. This length has been multiplied by 500. In order to get the real length, it must be divided by 500.
15 x 1/500
= 0.03 cm

Answer:
A. Chloroplasts and mitochondria replicate in a similar manner as some prokaryotes
Explanation:
Endosymbiont theory deals with how eukaryotic organisms were formed from prokaryotic organisms. Prokaryotes such as Bacteria were documented as the first form of life on earth through fossil records before eukaryotes came into light.
Organelles such as Chloroplasts and mitochondria replicate in a similar manner as some prokaryotes. This supports the endosymbiont theory that present-day eukaryotic cells are descendants of a successful symbiotic relationship between a host cell and an engulfed prokaryote
