Besides, mitochondria,vacuole and nucleus
"cell membrane - the thin layer of protein and fat that surrounds the cell. The cell membrane is semipermeable, allowing some substances to pass into the cell and blocking others.
centrosome - (also called the "microtubule organizing center") a small body located near the nucleus - it has a dense center and radiating tubules. The centrosomes is where microtubules are made. During cell division (mitosis), the centrosome divides and the two parts move to opposite sides of the dividing cell. The centriole is the dense center of the centrosome.
cytoplasm - the jellylike material outside the cell nucleus in which the organelles are located.
Golgi body - (also called the Golgi apparatus or golgi complex) a flattened, layered, sac-like organelle that looks like a stack of pancakes and is located near the nucleus. It produces the membranes that surround the lysosomes. The Golgi body packages proteins and carbohydrates into membrane-bound vesicles for "export" from the cell.
lysosome - (also called cell vesicles) round organelles surrounded by a membrane and containing digestive enzymes. This is where the digestion of cell nutrients takes place.
mitochondrion - spherical to rod-shaped organelles with a double membrane. The inner membrane is infolded many times, forming a series of projections (called cristae). The mitochondrion converts the energy stored in glucose into ATP (adenosine triphosphate) for the cell.
nuclear membrane - the membrane that surrounds the nucleus.
nucleolus - an organelle within the nucleus - it is where ribosomal RNA is produced. Some cells have more than one nucleolus.
nucleus - spherical body containing many organelles, including the nucleolus. The nucleus controls many of the functions of the cell (by controlling protein synthesis) and contains DNA (in chromosomes). The nucleus is surrounded by the nuclear membrane.
ribosome - small organelles composed of RNA-rich cytoplasmic granules that are sites of protein synthesis.
rough endoplasmic reticulum - (rough ER) a vast system of interconnected, membranous, infolded and convoluted sacks that are located in the cell's cytoplasm (the ER is continuous with the outer nuclear membrane). Rough ER is covered with ribosomes that give it a rough appearance.
smooth endoplasmic reticulum - (smooth ER) a vast system of interconnected, membranous, infolded and convoluted tubes that are located in the cell's cytoplasm (the ER is continuous with the outer nuclear membrane). The space within the ER is called the ER lumen. Smooth ER transports materials through the cell. It contains enzymes and produces and digests lipids (fats) and membrane proteins.
vacuole - fluid-filled, membrane-surrounded cavities inside a cell. The vacuole fills with food being digested and waste material that is on its way out of the cell." I quote from my science paper. It was exhausting! But I know all this so I added some extra.
All cells are surrounded by a cell membrane (option B).
A cell membrane is the semipermeable membrane that surrounds the cytoplasm of a cell.
Living organisms are made up of cells- a lot of them. These cells are the simplest unit and they contain smaller substances that perform different functions called organelles.
However, the cell and its internal organelles are surrounded by a structure called the cellmembrane.
The cell membrane functions to protect the cell from external hazards but also serves as a gateway for substances to enter the cell, hence, it is called semi-permeable.
Hence, the correct option is B.
The complete options are as follows;
A. Vacuole
B. Cell membrane
C. Cell wall
D. Nucleus

Cohesion is the term for molecules of a substance sticking together. One of the most common examples is water beading up on a hydrophobic surface. ... Because the water molecules' positive and negative charges are attracted to the positive and negative charges in the cellulose molecules in the paper.
When NAD+ becomes NADH, it is being reduced.
NAD+ is a coenzyme that is involved in many metabolic reactions. It is a dinucleotide, meaning that it is made up of two nucleotides. The nucleotides are nicotinamide adenine dinucleotide (NAD) and adenosine diphosphate (ADP).
NAD+ is oxidized when it loses an electron. This leaves the nicotinamide ring with an extra hydrogen atom, which gives NADH its name. NADH is a reduced form of NAD+.
The reduction of NAD+ is a necessary step in many metabolic reactions. For example, NADH is used in glycolysis, the process by which cells break down glucose to produce energy. NADH is also used in the Krebs cycle, the process by which cells break down carbohydrates, proteins, and fats to produce energy.

NAD+ accepts a hydrogen ion (H+) and two electrons (2e−), as it becomes reduced to NADH + H+. The NADH moves to the electron transport chain and donates a pair of electrons (becomes oxidized) to the first compound in the chain.
Explanation:
They are not valid because the student did not control all the variables that can affect plant growth
They are valid because the dependent variable caused a change in the independent variable.
They are not valid because the time frame to grow a plant is too short.
They are valid because the dependent variable caused a change in the independent variable.
Answer: Option C
Explanation:
The validity of a student’s result is basically based on how the dependent variable caused a change in the independent variable. A dependent variable is one which a scientist produce a variable and finds means to explain it in a proper way. An independent variable is one that is formed to compliment the dependent variable.
When the independent variable increases it causes decrease or increase in dependent variable. A intermediate or intervening variable is found which helps explain about the changes happening between the Independent and interdependent variable.
Answer:
Option (c) ''They are valid because the dependent variable caused a change in the independent variable'' is the correct answer.
Explanation:
The dependent variable is the one which is the center of observation. It is changed during the reaction and affected by it. When we measure the value of the reaction we always measure the dependent variable.
The independent variable is the one that is changed to cause the change in the value of the dependent variable. We can say that the dependent variable depends on independent for its reaction.
So dependent and independent variables are correlated with each other which tells the authenticity of the experiment.
