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.

Identify organelles in a plant cell.
The organelles in the plant cell that are shown in the image are: A: Chloroplast, B: Vacuole, C: Cell wall and D: Endoplasmic reticulum.
A: Chloroplast - This organelle is responsible for photosynthesis, the process by which plants convert sunlight into energy and produce glucose. Chloroplasts contain chlorophyll, a pigment that captures light energy.
B: Vacuole - The vacuole is a membrane-bound sac filled with fluid, primarily containing water and various dissolved substances. It plays a role in storing nutrients, waste products, and maintaining turgor pressure in plant cells.
C: Cell Wall - The cell wall is a rigid outer layer found in plant cells, bacteria, fungi, and some protists. It provides structural support and protection for the cell, helping maintain its shape and integrity.
D: Endoplasmic Reticulum (ER) - This organelle is involved in the synthesis, folding, modification, and transport of proteins and lipids. It can be rough (with ribosomes on its surface) or smooth (lacking ribosomes). The rough ER is involved in protein synthesis and modification.

D) It takes place in plant and animal cells and involves the division of cells.
Answer:
C
Explanation:
Cellular reparation tales place in both plant and animal cells, and it has to do with energy, using elimination all but C is crossed out.
Glucose+O2---(energy released)--> CO2+water
Hope it is correct
The process of cellular respiration takes place in plant and animal cells and
involves chemical reactions with oxygen to release stored energy.
Cellular respiration involves metabolic reactions which takes place in plant
and animal cells and converts chemical energy into energy in the form of
ATP and then releases waste products.
Cellular respiration usually takes place in the mitochondria as it is regarded
as the power house of the cell.

Atoms whose outer electron shells contain eight electrons tend to do what
Answer:
Atoms with a full valence shell are non reactive. Most shells have room for 8 electrons, so these atoms described are most likely noble gases. The answer is more or less nothing. They do not react because they have no electronegativity and no "extra" electrons
Explanation:
Atoms with a full valence shell are non reactive. Most shells have room for 8 electrons, so these atoms described are most likely noble gases. The answer is more or less nothing.
What is electronic configuration of carbon?Carbon atomic number is 6. Its electronic configuration is 1s2 2s2 2p2. As you can see from the electronic configuration the inner shell has 2 electrons and the outer shell with principal quantum number 2 has 4 electrons.
An atom is made up of electrons, protons and neutrons. Both protons and neutrons are located in the nucleus of the atom, while electrons are in the shell/s. The shell of an atom is the orbit on which the electrons revolve around the nucleus. The number of shells in an atom extends from the first, n =1, to infinity, n = ∞, depending on the number of electrons in the given atom.
The first shell, n =1, is the ground state and can only contain a maximum of 2 electrons. The inner shell contains two electrons and the outer shell contains four electrons.
Therefore, Atoms with a full valence shell are non reactive. Most shells have room for 8 electrons, so these atoms described are most likely noble gases. The answer is more or less nothing.

Why is plastic a non-biodegradable and nonpoint source of pollution?
Plastic is a non-biodegradable and non-point source of pollution because it cannot be broken down into degradable materials by micro-organisms. It comes from man-made substances and industries therefore, it is non-point pollutant.
What is Plastic?Plastic is a non-biodegradable and non-point pollutant. Because, the enzymes in the microorganisms cannot break down the waste into bio-degradable materials as microbes cannot recognize the bonds that hold these polymers together. Eventually, the polymers in plastic may break down, perhaps after hundreds of years. But after a long time, the damage is already done to the environment.
Nonpoint source of pollution comes from oil, pet waste, herbicide, bacteria, sediment, and any other contaminant that ends up on the ground naturally or from human activity.

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.

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.
