In an ionic compound, the attraction between actions and _________ hold the compound together

Nady [450]

Answer:
The correct option in blank is anion.

Explanation:
Ionic compound is formed by the transfer of electron from one atom to another atom. When an electropositve atom lose an electron it form cation, whereas as anion is formed when an atom gain an electron. These actions and anions then attract each other and form an ionic compound.
I hope it will help you.

Example:
The formation of NaCl is best example of ionic compound. Na has one electron in its outer most shell which can easily be removed to form Na+, while Cl has seven electron in its outer most shell so it can easily gain an electron lost by Na to form Cl-. Then these ions attract each other and form NaCl as shown in the figure.

Reverse transcriptase is an enzyme utilized by many retroviruses. This enzyme most likely demonstrates which type of activity

CaHeK987 [17]

Answer:

The activity of speed up the process.

Explanation:

Reverse transcriptase is an enzyme encoded from the genetic material of retroviruses that accelerate or speed up the process of transcription of retrovirus ribonucleic acid into deoxyribonucleic acid. Reverse transcriptase enzyme is also called RNA-directed DNA polymerase. Some retroviruses such as human immunodeficiency virus (HIV) and avian myeloblastosis virus used this Reverse transcriptase enzyme.

How does a vascular system serve the needs of a plant cell??

saw5 [17]

We first have to understand what a vascular system is. A vascular system consists of the water-carrying tube(xylem) and food-carrying tube(phloem). These 2 tubes are very essential for plants to survive. The xylem transports water to the leaves thru the stem to nourish the leaves so as to make food. The word equation is : Water + Carbon dioxide ----> Glucose + Oxygen. The phloem on the other hand transports the food from the leaves that creates them amd sent them to all parts of the plant. It is often a misconception that food is only sent to the fruits. The plant receives nutrition from the food that is made by the leaves. Overall the vascular system plays a very importamt roles in the survival of the plant.

To put it simple, think of the vascular system of a plant like the circulatory system of a human. Without the circulatory system, the human is unable to receive oxygen for breathing and remove carbon dioxide which is acidic in nature and pose a threat to the human body.
