Reproduction is one of the characteristics of living things and the ability to successfully execute this characteristics is termed fertility.
The opposite of fertility is sterility, which means the inability to produce offspring or reproduce.

Explanation:
DNA ___________ is important because it ensures that when a cell divides, the two resulting cells have the same genetic code. Pleaseee help
Answer: Replication
Explanation: When the cell is preparing to divide it will replicate its DNA so that both of the daughter cells will have a complete set of the DNA. It's like a book of instructions and the cell has to perfectly replicate it so that when it splits into two both of the new cells will have a perfectly made copy of it! Hope this helps :)

what substances are the reactants in photosynthesis
Answer:
The reactants of photosynthesis are everything to the left of the "———>" arrow, thus the reactants of photosynthesis are carbon dioxide, water, and sunlight energy.
The products of photosynthesis are everything to the right of the "———>" arrow, thus the products of photosynthesis are glucose and oxygen.
what is unique about HIV?
Answer:
HIV is called a retrovirus because it works in a back-to-front way. Unlike other viruses, retroviruses store their genetic information using RNA instead of DNA, meaning they need to 'make' DNA when they enter a human cell in order to make new copies of themselves.

A. meiosis
B. differentiation
C. senescence
D. mitosis
Answer:
D. mitosis
Explanation:
Mitosis is the process whereby the parent cell divides into two daughter cells that are identical.
Mitosis is the process by which a parent cell becomes two identical daughter cells. So, the correct option is (D)
What is mitosis ?Mitosis is the process in which cell duplication, or reproduction takes place. Wherein one parent cell gives rise to two genetically identical daughter cells. Mitosis is the duplication and distribution of chromosomes which carries the genetic information.
It is an important process in single celled eukaryotes as it is the mode of asexual reproduction. The main function of Mitosis is to produce more cells.
Life starts with single cell in multicellular organism which is formed from two gametes. Mitosis takes place one cell is divided into two cells as this single celled multicellular organism only carries genetic information in the form of DNA but not enough cells. These two cells further divide mitotically into four cells, then into 8 , then 16 and then 32.
It is essential to life because it give rise to new cells for growth and replacement of dead cells. It may take few minutes or some hours, depending on the type of cells. It depends on time, temperature and chemicals.
Thus, mitosis is the process by which a parent cell becomes two identical daughter cells. So, the correct option is (D).

the membrane activity most nearly opposite to exocytosis is:
Answer:
endocytosis
Explanation:
Endocytosis is defined as the process of trapping a particle or even a substance from the external environment by the process of engulfing it. The flexibility of the cell membrane helps the cell to engulf the food and also other materials from the external environment. Such a process is called endocytosis whereas exocytosis is the fusion of secretory vesicles with the plasma membrane and results in the discharge of vesicle content into the extracellular space
