If a device turned on then electrical currents flow through the device by which,
A magnetic field is created. Because all energy is released at once in static electricity.When a device that runs off of electricity is turned on, the flow of electrons is mediated through the process known as electric current.
What is Electricity?Electricity may be defined as a type of energy that typically results from the existence of charged particles like electrons or protons. It is a secondary source that commingles from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power, etc.
This flow of electrons also induces the formation of magnetic fields which involves the liberation of energy at once in the form of immobile electricity. All this process is obviously mediated by an electric switch that is responsible for breaking or closing an electric circuit.
Therefore, when a device that runs off of electricity is turned on, the flow of electrons is mediated through the process known as electric current.

What is DNA and why is it such a big deal to change an organism’s DNA?
Answer:
DNA Stands for Deoxyribonucleic acid and is the bodys' chemical blueprint. Changeing an organisms DNA can make the organism produce too much or too little protiens and can be fatal if the mutation/chance is significant enough.
Explanation:
Sarah is finishing a model drawing of a cell. She adds a membrane to the nucleus on her model. The nucleus of a cell has a membrane that isolates
material inside of it from the rest of the cell. Why does the nucleus need a membrane?
A.
The membrane helps the nucleus to create energy for the cell.
B.
The membrane helps the nucleus to create proteins for the cell.
C.
The membranes helps the nucleus to remove waste from the cell.
D.
The membrane helps the nucleus protect genetic material for the cell.
Answer:
C
Explanation:
a nuclear membrane is a double membrane that encloses the cell nucleus. It serves to separate the chromosomes from the rest of the cell. The nuclear membrane includes an array of small holes or pores that permit the passage of certain materials such as nucleic acids and proteins, between the nucleus and the cytoplasm .
What force creates the tides?
A. Solar Flares
B. Neptune’s gravitational force
C. Sun’s gravitational force
D. Moon’s gravitational force
Answer:
D.Moon's gravitational force.
Answer:
D) Moons gravitational force
Explanation:
Gravity and inertia act in opposition on the Earth's oceans, creating tidal bulges on opposite sites of the planet. On the “near” side of the Earth (the side facing the moon), the gravitational force of the moon pulls the ocean's waters toward it, creating one bulge.
Therefore saying, the moons gravitational force.

Define Habitat Isolation
Answer:
Habitat isolation occurs when habitat preferences lower the probability of mating between individuals associated with differing habitats. While a potential barrier to gene flow during ecological speciation, the effect of habitat isolation on reproductive isolation has rarely been directly tested.

1. Which of the following does NOT typically produce offspring with genetic variation?
a. Humans
b. Dogs
c. Trees
d. Bacteria
Answer:
d. Bacteria
Explanation:
They're the only creatures listed that can reproduce asexually. If something reproduces asexually, the offspring will have the same DNA as the parent unless a mutation occurs.
Hope this helps! Have a great day!
The bacteria does not typically produce offspring with genetic variation. hence, the option d is correct.
What produces offspring along with genetic variation?Se-xual reproduction does have the potential for generating the instant genetic variation in offspring. It is because of the independent assortment

O The gorilla and human are the most closely related organisms with the fewest differences in their amino acid sequences.
O The chimp and human are the most closely related organisms with the fewest differences in their amino acid sequences.
O The human and horse are the most closely related organisms with the fewest differences in their amino acid sequences.
O The monkey and gorilla are the most closely related organisms with the fewest differences in their amino acid sequences.
Answer:
d
Explanation:
d
The monkey and gorilla are the most closely related organisms with the fewest differences in their amino acid sequences. Hence option d is correct.
What are amino acid?Amino acid is defined as any of the elements present in both plants and animals that come together to produce a substance (protein), which is essential for a healthy body and for growth. The metabolism of amino acids plays a crucial role in many biological processes that take place inside the human body.
An examination of the first complete sequence of the gorilla genome suggests that humans and gorillas last coexisted 10 million years ago. The gorilla is the last of the surviving great apes, including humans, chimpanzees, orangutans, and gorillas, whose entire genetic sequence has been compiled.
Thus, the monkey and gorilla are the most closely related organisms with the fewest differences in their amino acid sequences. Hence option d is correct.
