Answer:

sodium and bromine

Explanation:

The one valence electron from sodium would be transferred to the bromine atom so they can both have an octet.

Which two atoms form an ionic bond?

Answer : A

Explanation : Ionic bond is a type of chemical bond and binds the chemical molecules together. Ionic bond is formed by the transfer of electrons from an electropositive element ( metal) to the electronegative element (non metal).

Sodium is an electropositive element and contains one positive charge. Bromine is an electronegative element with a single negative charge over it. Sodium gives the electron to bromine and results in the formation of ionic bond.

Thus, the correct answer is option (C).

If mammalian cells receive a go-ahead signal at the G1 checkpoint, they will complete the cell cycle and divide normally.

The cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next nuclear division.

There are three major checkpoints in the cell cycle. One at the end of the G1 phase, the second at the end of the G2 phase, and while third is during the M phase.

Therefore, if mammalian cells receive a go-ahead signal at the G1 checkpoint, they will complete the cell cycle and divide normally.

Explanation:

The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas.

There are 2 of them :-

1) Phagocytes

2) Macrophages.

These WBCs attach themselves to disease causing pathogens & then engulf them resulting in the destruction of the pathogens.

Answer:

Air quality is affected by natural processes. Wind can move pollutants from their source to far-away locations. It can still spread and harm living creatures and destroy their environments.

Explanation:

Air quality is affected by natural processes where wind can carry pollutants to places far away from their source which can still spread and harm living beings and destroy their environments.

Pollution is defined as the introduction of harmful materials into the environment where the harmful materials are called pollutants. Pollutants can be natural, such as volcanic ash which can also be created by human activity, such as waste or runoff produced by factories. Pollutants harm the quality of air, water and land.

Many things produce pollution such as cars spewing pollutants from their exhaust pipes. Burning coal to generate electricity pollutes the air. Industries and homes generate waste and sewage that can pollute land and water. Pesticides which is chemical poisons used to kill weeds and insects which is seep into waterways and harm wildlife.

Thus, air quality is affected by natural processes where wind can carry pollutants to places far away from their source which can still spread and harm living beings and destroy their environments.

Reinforcement and support

parenchyma, in plants, tissue typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with differentiation, to various functions. The cells are found in many places throughout plant bodies and, given that they are alive, are actively involved in photosynthesis, secretion, food storage, and other activities of plant life. Parenchyma is one of the three main types of ground, or fundamental, tissue in plants, together with sclerenchyma (dead support tissues with thick walls) and collenchyma (living support tissues with irregular walls).
