Electric current is the flow of ________ through a substance.
Answer:
Electrons
Explanation:
Answer:
A current is a flow of electrons for this to happen there must be a closed circuit.
- The electricity is nothing but a flow of free electrons present in the external surface of the electricity conducting substance.
The flow direction of this electron flow is also the direction of electricity flow.
- There is a type of electrical circuit which is known as the closed circuit. This circuit is completely connected with the two terminals of the battery and there are no hindrances in the path of electricity flow in these circuits. That's why current can only flow through these complete circuits.
What happens during the process of translation?
Explanation:
Translation is the process by which a protein is synthesized from the information contained in a molecule of messenger RNA (mRNA). Translation occurs in a structure called the ribosome, which is a factory for the synthesis of proteins.

Which is the best way to describe the biodiversity of an area?
Answer:
The best way to describe of biodiversity in a area is a grassland with a wide variety of organisms living on it.
Explanation:
A scientist separates a population of lizards into two groups. What would
most likely increase the rate of speciation in this population?
A. Have one group breed twice as often as the other.
B. Keep the two groups apart, but in identical ecosystems.
C. Force the two groups to breed with each other.
D. Have one group live with a much stronger predator.
Answer:
Hi, there your answer is D. Have one group live with a much stronger predator.
Explanation:
Having one group live with a much stronger predator will most likely increase the chances of speciation.
What is speciation?It is a process by which a new species of an organism is created.It occurs due to evolution.It occurs when a portion of population gets separated from the original population and evolves different characters that are heritable.Will speciation occur if :one group breeds twice as often as the other? No, because no selective force is acting on it.both groups are in identical ecosystem? No, since no reason for adapting and evolving a new character will be there.both groups interbreed? No, there is no competition, no struggle for existence and hence no evolution occurs.one group lives with a strong predator? Yes, since they will evolve evasive mechanisms and characters.To learn more about species, evolution, and predator here,

What was Darwin’s conclusion about the shells in Santiago
Answer:
Darwin noticed that the plants and animals on the different islands also differed. For example, the giant tortoises on one island had saddle-shaped shells, while those on another island had dome-shaped shells (see Figure below). People who lived on the islands could even tell the island a turtle came from by its shell.

Archaea (or extremophiles) like to live in extreme environments.
A. True
B. False
Answer:
A. True
Explanation:
We could just split the two parts of "extremophile'' and we get the gist.
"extremo-" (from Latin extremus) means to the highest degree of something.
"-phile" (from Greek philia), means love.
As a result, the term means "loving being in the highest degree (or something like that)."
To explain things, archaea are adapted to these extreme environments (hence the name extremophiles), except for hyperthermophily. Fungi, for example, live in mining areas, which are acidic and metal enriched.
Another term for the light-independent reactions of photosynthesis.
A. The Calvin Cycle
B. Cellular respiration
C. The nitrogen cycle
Answer:
A. The Calvin Cycle
Explanation:
The light-independent reactions cover half of photosynthesis, with the other half being the light-dependent reactions. Another word for this process is the Calvin cycle. It is named after the biologist, Melvin C. Calvin, who discovered it. The Calvin cycle is responsible for turning carbon dioxide into glucose. It also requires no light, hence its other name. Additionally, because it is occasionally called the Calvin cycle, sometimes, the light-dependent reaction is simply called the light cycle.
Answer:
A. The Calvin Cycle
Explanation:
The Calvin Cycle is the another term for the light-independent reactions of photosynthesis. So, option (A) is the correct answer.

by many scientists. Evolution by way of natural selection is most likely which type of concept?
an explanation of phenomena that can be accepted as true because it is supported by repeated observations and
experimentation
a likelihood based on the chance that a particular event will or will not occur during an experiment
a testable explanation or answer to a scientific question based on prior knowledge or research
a statement of fact that is accepted as true because it has always been observed to be true through observations
and experimentation

Explanation:
Why did Gregor Mendel choose to use purebred plants in his experiments?
A They reproduce sexually.
B They exhibit only one form of a trait.
C They have a variety of traits.
D They reproduce asexually.
Answer:
B
Explanation:
Gregor Mendel chooses to use purebred plants in his experiments because they exhibit only one form of a trait. The correct option is B.
What is Mendel's experiment?Mendel altered pure pea plant lineages. First-generation hybrids (F1) displayed dominant qualities like purple flower color while hiding recessive traits like white bloom color.
But in second-generation (F2) pea plants, recessive characteristics returned in a 3:1 ratio (dominant to recessive). Every pea plant has both male and female reproductive organs, and they all typically procreate by self-pollinating.
This was crucial to make sure that there were no other factors influencing the result of the cross when he crossed two plants with different features.
Therefore, the correct option is B, They exhibit only one form of a trait.

The overall process of photosynthesis can be written as the equation:
A. 6 glucose + 6 water --> 6 oxygen + 6 carbon dioxide + light
B. 6 water + 6 carbon dioxide (+ light) --> 6 oxygen + glucose
C. 6 oxygen + 6 water (+ light) --> 6 glucose + carbon dioxide
Answer:
B. 6 water + 6 carbon dioxide (+ light) --> 6 oxygen + glucose
Explanation:
Remember that in a chemical equation the reactants (input) are on the left and the products (output) are on the right. For photosynthesis to occur 3 different reactants are needed: water, carbon dioxide, and light. Note that because the light is not an element or molecule, it is sometimes written in paratheses or left out of the equation. Then, the products are glucose, which is the intended product, and oxygen, which is an unintentional byproduct that is released back to the atmosphere. Additionally, the equation for cellular respiration is the opposite of this, with the products as reactants and vice versa (except ATP is switched in for light).

What are valence electrons?
A. the atomic mass
B. the atomic number
C. all of the electrons in an atom
D. electrons in the outermost energy level
Answer:
D
Explanation:
The simple answer is the electrons in the outermost energy level.
Hydrogen has 1 electron in the outermost energy level.
Magnesium has 2 so this tells you that magnesium has a charge of 2
Oxygen has 6 oxygen has a charge of - 2
Fluorine has 7
For most elements, the electrons in the most outer ring determine the valence of the element.
Notice that the non metals work differently than the metals. Mg may have a charge of 2 and that is the number of electrons in the valence right.
Oxygen is a non metal it has a charge of - 2. It gets 6 electrons by subtracting the number of its charge from 8.
Answer:
D. electrons in the outermost energy level
Explanation:
The valence electrons are the electrons in the outermost energy level.
The atomic number determines an elements identity and shows the number of _________________ in the atom.
