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 :)

The fish shown here is normally found in a pond but is being studied in an aquarium. The amount of water and salt intake and excretion is measured as the fish maintains homeostasis. What scientific
question is most likely being asked based on the information in the model?
Based on the information in the question, we can infer that the question being asked is most likely "What mechanisms do fish use to maintain homeostasis in salt-water environments?".
What is homeostasis?Homeostasis is a series of regulatory processes by which an organism maintains core values (or range of values) necessary for everyday life.How to test the questionThe question is in the form of a hypothesis.This means that the scientist must first propose a possible solution to the question.Then, the scientist will make observations based on this question. In this case, it would seem the scientist has placed the fish into an environment that differs from its natural habitat, in order to observe how the fish maintains homeostasis.
Therefore, we can infer that the most likely question being asked is in regards to the way in which fish maintain homeostasis.

What's a recycling plant and how are electromagnets used there?
Answer:
A recycling plant is a factory for processing used or abandoned materials. The different types of recycling plants include those that process glass, metals, and paper back into raw materials. Other plants focus on items that require complicated recycling processes, such as concrete, electronic equipment and various plastics.
Electromagnets are used to lift and manoeuvre the crushed up ferrous materials or again to extract them from a pile of scrap. Ferrous materials are heavy and sharp but with the strength of the electromagnets they can be lifted and moved around with ease.

What is the name given to the process by which a parent cell becomes two identical daughter cells?(1 point)
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).
