Answer:

During a chemical reaction, what happens to matter? An atom is regrouped or rearranged during a chemical reaction. During chemical reactions, two or more chemical bonds are formed or broken, not atoms

Explanation:

A chemical change produces a new substance, while a physical change does not. Reactions involving chemical elements involve combining them. New, different chemical and physical properties result from the chemical reaction. The chemical reaction cannot destroy or create matter. A new substance is formed when particles of one substance are rearranged.

Answer:

building up antibodies in the immune system of those who get a vaccine

Explanation:

A vaccine is a small amount of the live virus being fought, given in such a small amount that is will not get you too sick for your body to fight it off. By inserting that small amount of the virus into the body it can build up its immunity to that virus. This means if the immunized body gets exposed to the virus later it already has its antibodies built up to fight off the virus in full. think of it as a set of instructions on how to get rid of this thing that is attacking you.  when mass quantities of the vaccines are spread through a population, the virus has a lesser probability of making lots of people badly sick. But the vaccine will only do its job if a lot of people get it.

Answer:

plant leaves contain openings called stomata, which allow the diffusion of gas exchange

Plant leaves contain openings called stomata, which allow the diffusion of gases.

Plants are living organisms that obtain carbon dioxide (CO2) gas from the atmosphere and give off oxygen gas in the process of photosynthesis.

They contain a structure that opens and closes on their leaves called stomata. This stomata functions as a means of gaseous exchange between the plant and the environment.

Therefore, plant leaves contain openings called stomata, which allow the diffusion of gases.

Hope this Helps

Organisms can be separated by their most basic characteristics into the broadest groups known as Kingdoms.

It is a taxonomic group composed of smaller groups called phyla. The classification of living organisms into kingdoms is a way of organizing the diversity of life into manageable categories.

The most widely recognized system of classification is the Five kingdom classification which was given by Robert Whittaker which recognizes kingdoms such as- Monera, Protista, Fungi, Plantae and Animalia.

Each kingdom is further divided into smaller groups based on increasingly specific characteristics until the species level is reached. The system of classification is constantly being refined with the discovery and interrelationship between different organisms.

Explanation:

The process of osmosis is the diffusion of water across a membrane. It is crucial for organisms to balance water between themselves and their surroundings.

Since this cell is placed in a solvent containing more solutes than inside the cell, the cell is considered to be in a hypertonic solution, and thus will expel water out.

Cell body The part of the neuron that contains the nucleus, which directs the manufacture of substances that the neuron needs for growth and maintenance.

Explanation:

brainliest pls

The part of the neuron directs the manufacture of substances that help the neuron grow in the cell body. The correct option is b.

The cell body, dendrites, and axon are the three components that make up a neuron. The majority of the molecules that the neuron requires to survive and operate are produced in the nucleus, which is part of the cell body.

The chromosomes, which make up the genetic makeup of the cell, are located inside the nucleus. The nucleus regulates protein synthesis through these chromosomes, as well as cell growth and differentiation into its final form.

The neurotrophins serve as axon guidance molecules, encourage synaptogenesis, and support the growth and survival of neurons.

Therefore, the correct option is b, cell body.
