Which factor distinguishes the experimental group from the control group

AysviL [449]

A control group is sort of the normal group. The group you aren't changing or messing with. It is to show what the species/experiment acts like on its own in response to something without you having to change it at all.

With an experimental group, you are changing something about the subject before putting it in the conditions it will need to respond to.

I don't entirely understand, but I know the control group is constant, unchanging. It sort of helps with distinguishing things. I have examples of experiments if that will help you understand what a control group is to answer the question. I also have a The Death Cure example if you have seen or read the book. I hope you do not fail this assignment, but even if I did not answer with an answer you were looking for, it could have helped you answer the question on your own.

I saw somewhere a similar question, though I was given the answer choices. If this is the answer you are looking for: variable(s).

Control groups don't use variables because you aren't changing them.

What is the difference between the life cycle of ferns and the life cycle of humans?

Bond [772]

Ferns make their own food. They grow and reproduce using spores instead of things like seeds. Humans on the other hand have to ingest food from their surrounding and when mature reproduce sexually. They can also choose if they want to reproduce or not while ferns don't have that option. Sexual reproduction is based on inseminating and egg cell, while ferns don't worry about this because the spores just fall on the ground.

Calculate the mass defect for oxygen-16 given this data. Round to the 5es001-1.jpg decimal place. mass of an oxygen-16 atom: 15.

Naya [18.7K]

Answer:

Explanation:

Given parameters:

Mass of oxygen atom = 15.994914amu

Mass of a proton = 1.00728amu

Mass of a neutron = 1.00866amu

Unknown:

Mass defect = ?

From the periodic table, the number of the elementary particles in a neutral Oxygen atom is given below:

Number of protons = 8

Number of neutrons = 8

Number of electrons = 8

Solution

The mass defect examines the difference between the actual mass of an atom and sum of masses of the nucleons.

The mass of an atom is concentrated in the nucleus which contains protons and neutrons. Electrons have little to no weight compared with the nucleons.

To calculate the mass defect, we first know the mass of the nucleons first:

1 proton has a mass of 1.00728amu

8 protons will weigh: (8 x 1.00728)amu = 8.05824amu

For the neutrons:

1 neutron has a mass of 1.00866amu

8 neutrons will weigh: (8 x 1.00866)amu = 8.06928amu

Mass of the nucleons = mass of protons + mass of neutrons

= 8.05824amu + 8.06928amu

= 16.12752amu

The mass defect = mass of the nucleons - mass of the atom

= 16.12752amu - 15.994914amu

= 0.132606amu ≅ 0.13261amu to 5 decimal places

Phycobiliproteins are A. found in purple sulfur bacteria.B. found in cyanobacteria.C. used to gather wavelengths of light that a

larisa86 [58]

Answer:

The correct answer is option E.

Explanation:

The deep-colored, water-soluble proteins, which are mainly found in Rhodophyta and cyanobacteria are known as phycobiliproteins. They captivate the light energy and then pass it to the chlorophyll at the time of photosynthesis.

They are comprised of proteins and are covalently attached through cysteine amino acid chromophores known as phycobilins. Thus, the correct answer is option E.
