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.

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,

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).

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.

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.

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.
