In Activity 2, the respirometer C serves as the control. A control is an essential part of any scientific experiment as it provides a baseline against which the experimental results can be compared.

Respirometer C containing only plastic beads does not contain any living organisms and therefore does not undergo cellular respiration. By comparing the results of respirometers A and B with the control (respirometer C), any changes in oxygen consumption and carbon dioxide production can be attributed to the metabolic activity of the germinated beans in respirometer A and the dormant beans in respirometer B.

This allows researchers to determine the specific effects of germination on cellular respiration by isolating the variables and eliminating any external factors that could influence the results.

Explanation:

Phytoplankton, cyanobacteria, algae, and green plants are examples of autotrophs that make up the producers in a food-chain. All organisms are regarded as consumers if they depend on other living things, such as plants, for food.

Decomposers are creatures that obtain their energy from organic waste or dead things. To survive and develop, any organism human, plant, or animal needs to consume energy. This procedure is ongoing constantly. As an illustration, grass grows on a grassland. It produces its own nourishment, which it obtains from the sun. The rabbit eats the grass since it is a consumer and needs to eat something to get energy. The following customer, a coyote, consumes the rabbit. When a coyote dies, worms and bacteria, which are decomposers, consume it and break it down, returning its nutrients to the food chain to be used once more. Complex food webs are created in ecosystems by the connections between many diverse food chains.

To move charges, there needs to be a motive or a driving force that facilitates the flow of electric charges through a conductor. This motive can be provided by various factors and mechanisms.

One of the primary motives for the movement of charges is the presence of an electric field. An electric field exerts a force on charged particles, causing them to move in a particular direction. This force can be generated by applying a voltage difference across a conductor, creating an electric potential difference. The charges will naturally move from an area of higher potential to an area of lower potential, driven by the electric field.

In addition to electric fields, other motives for charge movement can include electromagnetic induction, where a changing magnetic field induces a current in a conductor, and chemical reactions, such as in batteries or fuel cells, where the conversion of chemical energy into electrical energy creates a motive for charge flow.

Ultimately, the motive for moving charges is provided by the presence of a force or potential difference that can overcome any resistances or obstacles in the conductor, allowing the charges to move and establish an electric current.

Explanation:

Answer:

If the active site is altered, the enzyme can no longer perform its catalytic activity

Explanation:

Changes in temperature or pH alters the structure of the enzyme. Enzymes have catalytic activity that lowers the activation energy required for a reaction to proceed.

Enzyme catalytic activity is facilitated by the active site - a specific region of the enzyme where the reactants bind.

At the active site, the conditions are optimal for the reaction to take place (the active site gets the reactants in the perfect position to make contact and react).

If the structure of the active site is compromised, it won't have catalytic activity anymore and won't be able to catalyze the reaction

According to the Big Bang theory, if you reverse the galaxy motion and go back in time A. Everything would become condensed into one dense point.

The Big Bang Theory simply explains how the universe was formed from a large explosion. According to the Big Bang theory, the universe was formed as a result of the explosion of particles.

The reverse of the Big Bang Theory simply means the scenario where the expansion of the universe reverses. This is also called the Big Crunch. This will lead to the recollapse of the universe.

In this case, the cosmic scale also reaches zero. Then, everything would become condensed into one dense point.

Answer: D. The reproductive cells have half as many chromosomes as the body cells.

For an organism that has 18 chromosomes in its body cells and its sex cells have 9 chromosomes, the correct statement is C, Its sex cells are haploid and a result of meiosis.

Haploid cells have half the number of chromosomes as diploid cells. Mitosis is a type of cell division that produces two identical daughter cells. Meiosis is a type of cell division that produces four daughter cells, each with half the number of chromosomes as the parent cell.

In the organism described, the body cells are diploid (18 chromosomes) and the sex cells are haploid (9 chromosomes). This is because the sex cells are produced by meiosis, which is a type of cell division that reduces the number of chromosomes by half. This allows the sex cells to combine with each other to form a new diploid cell, which is the beginning of a new organism.

We can see from the diagram that we are comprised of a deoxyribose sugar base and phosphate groups. We can also spot that there are nitrogenous bases present as well, specifically Adenine and Thymine.

Recall that DNA is comprised of a deoxyribose sugar and nitrogen bases Adenine, Thymine, Cytosine, and Guanine.

Since the diagram has both of these present, we can say that this biomolecule is DNA. If this biomolecule is DNA, then it has to be the holder of the blueprints of the cell. Recall also that DNA holds the genetic material of a cell.

Therefore, our best bet is answer choice B.

The average gives better information about the population than individual measurements.

The average of a quantity is used to reflect the weighted property of a system. For instance, in a bag of rice, there are so many grains. Each of these grains of rice has their individual weights and it could be difficult to measure them one after another.

It would be better to have a property that helps us to obtain a number that gives us an idea of the masses of all he grains of rice in the bag of rice without measuring them individually.

Thus, the average mass is more useful because it gives more information about the masses of all the grains of rice rather than individual masses.

Answer:

Matter is anything that has volume and mass.

Explanation:

Answer:

Cell volume is the amount of material inside the cell. Surface area is the total area of the cell's membrane. Ratio of surface area to volume is the surface area divided by the volume.

Explanation:

The amount of stuff inside a cell is measured by its volume. The overall area of a cell's membrane is its surface area. The surface area divided by the volume is known as the surface area to volume ratio.

In order to allow enough materials, such as food particles, to flow through the cell membrane fast for the cell's survival and optimal function, the ratio of cell surface area to volume in live organisms must always be very modest.

In a cell with decreasing size, the surface area to volume ratio (S/V) would rise as a result of a greater decrease in volume than surface area.

Therefore, a cell's volume is used to calculate the volume of its contents. The surface area of a cell is its total membrane area. The surface area to volume ratio is defined as the surface area divided by the volume.
