Control - group B

Constant - Task

<h3>Research variables</h3>

In every scientific investigation, there are different variables. These include:

Independent variables: These are the variables that are supplied by the researcher and often varied to produce different effects. It is often referred to as the 'cause' variable.
Dependent variables: These are variables that are measured in the course of research. They are a result of the effects of the independent variable on the experimental subjects or groups. They are otherwise known as 'effect' variables.
Constant variables: Variables that are applicable to all experimental groups and are usually kept constant.

Also, there are different groups in research:

Control group: The reference group. The group that is not fed with the independent variable and forms the basis for comparison in order to understand the effects of the independent variable.
The experimental group: The group that is fed with the independent variable.

Is a picked apple alive? Think about the five criteria: Contain cells, reproduce, Growth and Development, Obtain and use energy,

Stels [109]

Yes. They have cells, they have seeds to reproduce, and they respond to environment. Rotting is an example of an apple developing (although it is dying), using energy, and responding to the environment.

Which group is more likely to survive significant environmental change, one like black-footed ferrets with almost no variation o

Shkiper50 [21]

Mountain lions with lots of variation because variation is important for species’ survival. If there is an environmental change that negatively affects organisms with a certain trait, variation can insure that the entire species will not be wiped out because some organisms within that species might not have that trait and can survive.

Essential services, such as water purification, nutrient cycling, and plant pollination are all examples of earth's __________.

love history [14]

Essential services, such as water purification, nutrient cycling, and plant pollination are all examples of earth's Ecosystem services.

The ecosystem is defined as the interaction between the biological communities with its physical environment. The services provided by the ecosystem are termed as ecosystem services. The ecosystem with the help of its different components performs water filtration, recycling of the nutrients, pollination, seed dispersal etc. These all services provided by the ecosystem comes under the category of ecosystem services.

Group the terms according to the subatomic particle they describe.

LiRa [457]

Answer:

This question is incomplete

Explanation:

This question is incomplete but the completed question can be seen in the document attached.

There are three main subatomic particles namely electrons, protons and neutrons. However, the question only discusses two of them; electrons (negatively charged) and protons (positively charged).

A. Found in all matter

Answer: They are both found in all matter since all matter are made up of atoms and all atoms have both protons and electrons (and even neutrons).

B. Negative charge

Answer: The subatomic particle with negative charge (as discovered by R.A Millikan) is the electron

C. Exists in the nucleus

The subatomic particles found in the nucleus are the protons and neutrons.

D. Attract opposite charges

They both (protons and electrons) attract opposite charges because they are of opposite charges and generally unlike charges attract.

E. Moves at extreme speed

Of the two subatomic particles mentioned, electrons move faster than protons because of there lighter mass when compared to the protons. However, the fastest subatomic particle is the neutrino.

F. Bound by strong force

The protons are bound by strong nuclear force which binds them to the nucleus of the atom.
