Carbohydrates are a type of biological macromolecule required to carry out life functions. Which of the following is NOT true regarding carbohydrates?
A. Monomers of starch are sugars such as glucose.
B. Living things store extra sugars as complex carbohydrates.
C. They contain carbon, hydrogen and oxygen, usually in the ratio of 1:2:1.
D. Carbohydrates are the main component that makes up cell membranes
Answer:
D. Carbohydrates are the main component that makes up cell membranes
Explanation:
The main component of the cell membrane is a double layer of phospholipids - molecules with a phosphate head and fatty acid tail. Therefore D is incorrect. There are some carbohydrates in the cell membrane, but they are not the main component.
The statement 'carbohydrates are the main component that makes up cell membranes' is NOT true (Option D).
Carbohydrates are biopolymers composed of monosaccharide units linked by glycosidic bonds.Complex carbohydrates (e.g., starch) consist of large branched or unbranched chains of monosaccharides, while simple carbohydrates (e.g., glucose) are monosaccharides.Complex carbohydrates serve as sources of longer energy storage for the cells, while monosaccharides provide energy quickly.The main component of the cell membranes are lipids (i.e., phospholipids and cholesterol).In conclusion, the statement 'carbohydrates are the main component that makes up cell membranes' is NOT true (Option D).

3) mechanical to thermal (motion -> heat from the body causes sweating)
The potential energy is stored in the body chemically (via food). That potential energy is then released when the body is put in motion.
APT and photovoltaic cells are simikar because
The question is incomplete, below is the complete question.
ATP and photovoltaic cells are similar because
A. they are both key components of plant cells.
B. they both produce chemical and electrical energy.
C. they are both key components of solar panels.
D. they both use energy from the sun to separate electrons from atoms.
The correct answer to the question is option D
ATP and photovoltaic cells are similar because THEY BOTH USE ENERGY FROM THE SUN TO SEPERATE ELECTIONS FROM ATOMS.
Photovoltaic cells are otherwise known as solar cells,they are made of silicone that are specially treated,these specially treated silicon transfers solar energy gotten from the sun to electrical energy.
These solar powered photovoltaic panels converts the rays from the sun into electricity.this it does by exciting electrons found in silicon cells and also using the photons of light from the sun.
When this electricity is generated,it can be used to supply energy that is renewable to ones home or business.
In ATP, during the process of photosynthesis, sunlight penetrates the cell and further pass into the chloroplast. This light energy is further intercepted by granal stacks containing chlorophyll molecules, from then,some of those light energy are concerted to chemical energy,as this is going on,a phosphate is then added to a molecule to give rise to ATP.

Which answer best explains how most scientists think that planets form? A. Large chunks of matter break off a star that collides with another star; these chunks then become planets orbiting the star. B. Large chunks of matter break off a planet that collides with a smaller body; these chunks gradually clump together to become a new planet. C. A rotating cloud of space dust and gases begins to flatten and condense, forming a new star; the remaining matter forms an accretionary disc around the star, gradually coalescing to form planets. D. A rotating cloud of space dust and gases begins to condense, forming a protoplanet; if the protoplanet is massive enough, its gravity will attract nearby matter until the protoplanet becomes large and round enough to be considered a planet.
Answer: B
Explanation:
Thats what the teacher told me
The scientists believe that planets form when a rotating cloud of space dust and gases flattens and condenses, forming a new star; the remaining matter forms an accretionary disc around the star, gradually coalescing to form planets, as described in Option C, also known as the "nebular hypothesis."
What is the nebular hypothesis?The nebular hypothesis is the most widely accepted scientific theory for the planetary systems, such that the solar system and, as per this theory, a cloud of gas and dust, called a nebula, collapse due to gravitational forces; the nebula contracts, and it rotates faster, flattening into a disk, which eventually cools and condenses, forming a protoplanetary disk.
Hence, the scientists believe that planets form when a rotating cloud of space dust and gases flattens and condenses, forming a new star; the remaining matter forms an accretionary disc around the star, gradually coalescing to form planets, as described in Option C, also known as the "nebular hypothesis."

(ANSWER NEEDED NOW PLS!!) your sister claims that
the digestive system works by itself to give your body energy. She states that small branches from the stomach get food to the cells throughout your body. Do you agree with this statement? Why?
My sister is right. The stomach has structures in its branches that see to the breakdown of food materials.
The digestive system is the system in the body that takes care of the breakdown of food materials and absorption of nutrients from food. The stomach houses most of the structures in the digestive system.
When food is broken down in the stomach, It is sent to other parts of the body via the circulatory system in the body. Therefore, my sister is right.

In the question “How does pineapple consumption affect the number of digestive bacteria?”, pineapple consumption is
A) the control group B) independent Variable
C) dependent variable D) experimental group
Answer:
For the approach of how does pineapple consumption affect the number of digestive bacteria?, pineapple consumption is the independent variable (option B).
Explanation:
The formulation of a hypothesis is not complete without the existence of the independent and dependent variables, the main variables from the research point of view.
The independent variable is one whose change or modification is capable of impacting the dependent variable, which is one that can be quantified or measured.
According to the approach, if somebody want to know how the consumption of pineapple influences the number of digestive bacteria, the independent variable is the consumption of pineapple, which can be controlled and modified, while the characteristic that is under the influence of this variable is the amount of bacteria, so that the latter is the dependent variable.
The other options do not apply because:
The experimental (D) and control (A) groups refer to the population in which the study is conducted. The dependent variable (C), in this case, is the amount of digestive bacteria.A classmate has asked you to help them determine the concentration of DNA in their solution. Their A260 reading was 1.69. What was the concentration of their DNA
Answer:
Acid , phenol or protein
Explanation:
The ratio of absorbance at 260 and 280nm is what is usually used to assess the purity which a DNA or RNA posses. A ratio of 1.8 is generally accepted as being pure for a DNA sample and a ratio of 2.0 is generally accepted also as being pure for RNA. when the ratio is significantly lower in each case, it indicates that there is presence of protein, phenol or other contaminants.

The diffusion of water molecules a secectively permeable membrane.
What is Diffusion?The net passive movement of molecules or particles from areas of higher concentration to areas of lower concentration is known as diffusion. There needs to be a concentration gradient for diffusion to happen.
The dissimilarity in the quantity of solutes, particles, or molecules between the two locations will drive them to travel between the two regions.
The gradient created by the uneven particle concentration between two fluids will cause the particles to move in order to balance the discrepancy in concentrations. However, solutes do not migrate in a single direction during the diffusion process.
Therefore, The diffusion of water molecules a selectively permeable membrane.

4) Cell C suddenly lost all its dynamin proteins. Which of the following will most likely happen
right
away as a result of this loss?
A) Transcription factor X will no longer be able to go to the nucleus
B) A vesicle bud will no longer be pinched off from a membrane
C) A vesicle will no longer be tethered to a target membrane
D) A protein will no longer be targeted to the mitochondrial matrix
E) Two of the above
Answer:
B) A vesicle bud will no longer be pinched off from a membrane
Explanation:
Dynamin is a protein responsible for endocytosis, the process where the cell takes substances in from outside the cell through a system of vesicles. At the edge of the cell, the membrane pinches in to form a vesicle, which buds off from the membrane and enters the cell.
The step of this process that dynamin is involved in is in cleaving newly formed vesicles from the membrane. Without it, a vesicle bud will no longer be pinched off from a membrane
