Which statement best describes the cell membrane of a living cell?
A) It is composed of proteins and carbohydrates
B) It has the same permeability to all substances found inside or outside the cell.
C) It is a double protein layer that doesn't allow things to pass through it.
D) It selectively regulates passage of materials into and out of the cell..
D) It selectively regulates passage of materials into and out of the cell.
The plasma membrane in a living plant cell is composed of a double lipid layer that gives it hydrophobic character and acts as a semi- permeable barrier. The partial permeability of the substances allows regulating the passage of substances from and to the interior of the cell. At the level of the plasma membrane there are several mechanisms and transport to allow the entry of substances needed for the cell or the output of synthesized products or metabolic waste, thus regulating the passage of substance in a selective way.They keep toxic substances out of the cell.They contain receptors and channels that allow specific molecules, such as ions, nutrients, wastes, and metabolic products.Therefore, correct option is D)

Explanation:
An experiment was designed to investigate the effect of caffeine on the heartbeat of Daphnia magna, or water fleas. These tiny, aquatic animals are used because their transparent bodies make it easy to see their hearts and measure their heart rates. Two populations of Daphnia were raised, (A) and (B). Both populations lived in tanks of water at the same temperature and received identical amounts of food. Every 2 hours, water fleas from both populations were selected and their heartbeats were monitored. Population (A) had 0.5 g of caffeine given to them five minutes before their heartbeat was checked. Population (B) were given 0.5 g of water and with no caffeine.
Answer:
This question is incomplete. It is asking to identify the following in the experiment:
Independent variable: CAFFEINE
Dependent variable: HEARTBEAT
Experimental group: POPULATION A, which were given 0.5g of caffeine
Control group: POPULATION B, which were not given caffeine
Constants: SAME TEMPERATURE, SAME AMOUNT OF FOOD, SAME TIME BEFORE CHECKING
Explanation:
Independent variable in an experiment is the variable which is changed or manipulated by the experiment. In this experiment, the independent variable is the CAFFEINE.
Dependent variable is the variable that is measured by the experiment or in other words, the variable that responds to changes made to the independent variable. In this experiment, the dependent variable is the HEARTBEAT measured.
The experimental group of an experiment is the group that receives the experimental treatment (caffeine). In this experiment, the POPULATION A of Daphnia magna, or water fleas are the experimental group because they received 0.5g of caffeine.
On the other hand, the control group is the group that does not receive the experimental treatment. In this experiment, POPULATION B did not receive any caffeine, hence, it is the CONTROL GROUP.
Constant or controlled variable are those variables that the experimenter must keep unchanged for all groups throughout the experiment, in order not to influence the experiment's outcome. In this experiment, the constants are: SAME TEMPERATURE, SAME AMOUNT OF FOOD, SAME TIME BEFORE CHECKING (2hrs)

what does DNA use to store information
Answer:
DNA stores biological information in sequences of four bases of nucleic acid — adenine (A), thymine (T), cytosine (C) and guanine (G) — which are strung along ribbons of sugar- phosphate molecules in the shape of a double helix.
Explanation:
DNA uses the complimentary base pairs to store information in organisms.
The base pairs comprises of the nucleic acid include adenine (A), thymine
(T), cytosine (C) and guanine (G) .
The base pairs contain unique amino acid sequences which represent a
unique trait in organisms. Any alteration in this pair will lead to a different
result or mutation which is why it is very important and has to be rightly
paired .

Mario and several friends spend a day at the beach. While watching the ocean waves crashing to shore, Mario wonders how much of the world's water is contained in different types of bodies of water such as oceans, lakes, and rivers. He decides to research the percentage of Earth's water found in different locations. Which does his research reveal? Multiple choice question. A) Less than 3 percent of Earth's water is freshwater containing no salt. B) The ice caps located at both poles contain 30 percent of Earth's water. C) Fifty percent of Earth's water is in oceans and the glaciers at the poles. D) Ninety percent of Earth's water is in lakes, rivers, and groundwater.
Answer:
A
Explanation:
The correct answer here would be that less than 3 percent of Earth's water is freshwater containing no salt.
Generally speaking, about 71 % of the earth is made up of water. Out of this percentage, approximately 97 % is found in the oceans with less than 3 % being freshwater. About 68.7 % of the freshwater is locked-up as glacier and ice, 30.1 % is groundwater, while the remaining 1.2 % represents surface and other forms of freshwaters which include ground ice and permafrost, lakes, atmosphere, rivers, swamps and marshes, soil moisture, and the freshwater in living organisms.

The hardest coal has the most energy and burns the cleanest. Where do coal miners find the HARDEST coal?
A. on the surface of the earth
B. in the oceans
C. deep beneath the earth’s surface
D. at the bottom of shallow lakes and rivers
Answer:
C
Explanation:
This coal will be more compact and therefore most of the water and CO2 has been expelled due to this. This coal is called Anthracite and burns the cleanest. It is often found in areas with high stress and lots of pressure so mainly far underground. Why do you think the the majority of mines are underground and not open sites? So that they can get to the best coal the most economic and ergonomically way possible

How are photosynthesis and cellular respiration related?
Answer:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
I hope that helps determine your answer.
The product of photosynthesis are the reactants of cellular respiration.
What is cellular respiration?Cellular respiration is the process by which cells convert the energy stored in food molecules into a form of energy that can be used by the cells.
This process takes place in the mitochondria of the cell and involves the oxidation of glucose (sugar) to produce ATP (adenosine triphosphate), which is the main energy source for cellular processes. Cellular respiration has several stages, including glycolysis, the citric acid cycle, and the electron transport chain, each of which contributes to the generation of ATP. The end product of cellular respiration is carbon dioxide and water.
