In the cells of humans and other animals, a great deal of energy is dedicated to operating a pump that transports sodium (Na+) ions out of cells and potassium (K+) ions into cells. This transport creates a chemical and electrical gradient. Maintaining the proper balance of sodium and potassium is critical to ensuring that nerve cells work properly. Nerve cells drive muscle contractions—including heart muscles—and are responsible for animals’ abilities to sense their environment and for humans’ ability to think.
Scientists gain a better understanding of the sodium-potassium pump by creating models of what the pump accomplishes. Such models are used to examine many other complex processes as well.
This model of the sodium-potassium pump illustrates the process by which sodium is pumped out of cells and potassium is pumped in. The sodium-potassium pump moves the two different ions in opposite directions.
Where in a cell does this transport process take place?
A.
nucleus
B.
cell wall
C.
cell membrane
D.

The Transport process takes place in cell membrane.
What is Transport?Cell transport describes the transportation of a material across a cell membrane. The chemical has the ability to enter or exit cells.
The plasma membrane and cell membrane are both permeable to different substances. The nature of the plasma membrane is quite selective.
Cell transport is very important for transport of molecules. There are two transport of cell transport of endocytosis and exocytosis.
Therefore, The Transport process takes place in cell membrane.

mitosis
asexual reproduction
binary fission
sexual reproduction
Answer:
The answer to this question is B.) asexual reproduction
Explanation:
Hope this helps :) !!!!!!!!!!!!!!!!!
In asexual reproduction fewer offspring are produced. Asexual type of reproduction is the type of reproduction in which single parent is involved. Thus, option B is correct.
What is asexual reproduction?
Asexual reproduction is defined as the mode of reproduction in which only single parent is involved and in asexual reproduction fewer offspring are produced. There are several types of asexual reproduction and these are binary fission, spore formation, vegetative reproduction, and fragmentation.
Reproduction has been defined as the process that has been carried out by the living organisms and during the process of the reproduction the living organisms produces their own young ones and feed them. Reproduction has the supreme quality of the living things.
There has been two types of the reproduction and these are the sexual as well as asexual reproduction. The process of the reproduction in which two parents has been involved has said to be sexual mode of reproduction and the process of the reproduction in which only single parent has been involved in known as asexual mode of reproduction. The example of asexual reproduction are budding, fragmentation, spore formation, and binary fission.
Therefore, In asexual reproduction fewer offspring are produced. Asexual type of reproduction is the type of reproduction in which single parent is involved. Thus, option B is correct.

Which of the following is true about subatomic particles?
The mass of a neutron is equal to the mass of a proton
Neutrons have no charge and are the lightest subatomic particle
Electrons are negatively charged and are the heaviest subatomic particle
Protons are positively charged and the lightest subatomic particle
Answer:
Neutrons have no charge and are the lightest subatomic particle
Explanation:
Nucleus of an atom contains three subatomic particles. These are protons, neutrons and electrons.
Mass of a proton is [tex]1.67[/tex]×[tex]10^{-27}[/tex]kg.
Mass of a neutron is [tex]1.67[/tex]×[tex]10^{-27}[/tex]kg.
Mass of an electron is [tex]9.1[/tex]×[tex]10^{-31}[/tex] kg.
Also, protons are positively charged, neutrons have no charge and electrons are negatively charged.
Therefore, we can conclude that the mass of a neutron nearly equals the mass of a proton.

2. Explain why glucose continues to enter a cell, even when the concentration inside the cell might be higher than outside.
Answer:
Both diffusion and facilitated diffusion are driven by the potential energy differences of a concentration gradient. Glucose enters most cells by facilitated diffusion. ... Na+ is maintained at low concentrations inside the cell and K+ is at higher concentrations. The reverse is the case on the outside of the cell
Glucose continues to enter a cell, even when the concentration inside the
cell might be higher than outside as a result of the process known as active
transport.
Active transport involves the movement of molecules through a
cell membrane against the concentration gradient. Examples include:
Antiport Pumps.Symport Pumps.This type of transport requires the use of energy such as ATP to move the
glucose molecules into the cell.

why is a floating ice layer important to aquatic organisms?
Answer:
It helps life survive on Earth.
Explanation:
Since water ice floats, it helps life survive on Earth. This ice layer insulates the water below it, allowing it to stay liquid, which allows the life within it to survive. If ice sank, the liquid water on top would also freeze and sink, until all the liquid water became frozen.

A particular type of potato can only be produced by cloning from it's eyes or budding. Large commercial growers worldwide now plant only this particular type. Some scientists are warning that exclusively growing this type of potato by asexual reproduction presents a serious disadvantage. Why are these scientists concerned?
If an economically important crop such as the potato as highlighted in the illustration can only be produced by cloning, it is normal for scientists to be concerned because a single even of disease attack might end up wiping the entire crop away.
Cloning is more or less mitosis - a division of vegetative cells. In other words, there is no form of genetic recombination in clones. All clones have exactly the same genes as themselves and their parents.
The implication of an entire population of an organism having the same genetic composition is that they will be resistant and susceptible to the same limiting factors - be it biotic or abiotic. Just an event of a disease outbreak might end up wiping all the population away because there will not be any resilience.

Plz help I need help
Answer:
The cell theory states that all living beings are made of cells. There is a debate as to whether or not viruses should be considered to be alive. The debate results from the fact that viruses cannot reproduce on their own. They must invade a host cell and utilize the host’s genetic material in order to reproduce. Viruses are not true cells. They lack the most important part of the cell, the protoplasm. Hence, the cell theory is not applicable to viruses. Hence, the answer is C.

Which of the following evidence supports the theory of plate tectonics?
The age of rocks and mountains on the edge of neighboring continents varies.
Fossils from the same species are found on only one continent.
Iron-rich, molten magma rocks no longer align to Earth’s poles in many locations.
Grooves created from glacier movement travel in opposite directions on each continent.
The characteristics of the tectonic plates allows to find the result for the correct statement is:
Iron-rich, molten magma rocks no longer align to Earth’s poles in many locations.
The tectonic plate model establishes that by the hot magma convection currents the solid crust breaks in the weakest areas, forming plates that move floating on this, hot magna that can rise through the cracks and separate these plates.
In the attached we see a diagram of the magnetic alignments in the rocks from a tectonic plate, we can see that the alignment changes due to the inversion of the earth's magnetic field in such a way that we can appreciate the separation of the two plates.
Another proof is that other similar animals are on continents separated by great distances.
Let's analyze the different claims:
a. False. Radioactive dating evidence gives that the rocks give that the rocks on the two continents are the same age.
b. False. Fossils of the same spice are found on several continents.
c. True. These rocks when they emerged were aligned and when moving and the magnetic field reversed the rocks are no longer aligned, this is one of the greatest proof of the separation of tectonic plates.
d. False. The furrows of the glaciers go from the North to the South, it does not have the direction of the displacement of the plates.
In consequence of the characteristics of the tectonic plates we can find the result for the correct statement is:
Iron-rich, molten magma rocks no longer align to Earth’s poles in many locations.
