Could someone help me out with this easy question? I wasn’t in class today.

Answer:

4

Explanation:

Answer:

Velocity

Explanation:

Given the change in positive (direction) over time we are given the velocity formula.

V = Change in direction/Change in time

Since we are given a direction we can rule out speed as well as direction in itself. We can also rule out acceleration because that is the change in Velocity divided by change in time.

Answer:

macromolecules: carbohydrates, lipids, proteins, and nucleic acids.

so the answer is macromolecules  

Explanation:

Adenosine triphosphate (ATP) production, the creation of sugar and alcoholic esters, and other energy-transfer processes all need phosphorus.

In many enzymatic processes, where inorganic phosphorus regulates the rate of reaction, phosphorus also serves a regulatory purpose in addition to these other tasks.

This holds true for everything from exploration to the development of young children and is determined not by our muscles and lungs but rather by the amount of energy we can obtain from food.

It has a significant impact on how the body utilizes fats and carbs. The production of protein by the body is also necessary for the development, upkeep, and healing of cells and tissues.

Therefore, the way energy puts limits on life and the way phosphorus is different.

Answer:

Nitrogen and oxygen are by far the most common; dry air is composed of about 78% nitrogen (N2) and about 21% oxygen (O2). Argon, carbon dioxide (CO2), and many other gases are also present in much lower amounts; each makes up less than 1% of the atmosphere's mixture of gases.

Answer:

D16.5 degree F. Explanation : when x = 9: y = 25.2 + 3.3(9) = 54.9 deg. when x = 5 more chirps or 14: y = 25.2 + 3.3(14) = 71.4 deg. 71.4 - 54.9 = 16.5 deg.

Explanation:

ok

The first cricket: the sky's the limit. 9 chirps in a quarter of a minute, or 15 seconds, are equivalent to 36 chirps in 60 seconds. In the same amount of time, the first cricket makes 12 chirps.

When x = 9: y = 25.2 + 3.3(9) = 54.9 deg. When x = 5 more chirps or 14: y = 25.2 + 3.3(14) = 71.4 deg. 71.4 – 54.9 = 16.5 deg.

As the temperature rises, it gets simpler to reach a particular activation energy, which speeds up chemical processes like the one that causes a cricket to chirp.

On the other hand, as the temperature drops, the reaction speeds slow and the chirping also decreases.

Although the amount of light has no bearing on their chirp, temperature does: warmer air causes a faster chirp.

The number of cricket chirps over a 15-second period multiplied by 37 will often give you the temperature in degrees Fahrenheit.

Therefore, The cricket is chirping because of the vibrations produced while the scraper is moved along the file.

Answer:

It should be solid.

Explanation:

Solids have little to no movement in their particles. If you were to fill it to the top and shake, not much would move, therefore representing solids.

Particles are the unit that makes the matter. The states of matter based on particles can be solid, gas, or liquid. The matter in the experiment represents solid matter.

The phases or states of matter are based on the composition and the distribution of the particles of the object. There are four known and observable states of matter namely solid, gas, plasma, and liquid.

The gas is the freest and most spaced particle with no fixed volume and shape. On the other hand, the particles of a liquid are a little closer than the gas but do have an indefinite shape.

The solid has particles closely packed with no space, which makes them have a definite shape and volume. When a container filled with particles is shaken, there is no movement as they are very closely packed, like solid.

Therefore, the container represents solid matter.

There are four types of consumers: omnivores, carnivores, herbivores and decomposers. Herbivores are living things that only eat plants to get the food and energy they need. Animals like whales, elephants, cows, pigs, rabbits, and horses are herbivores. Carnivores are living things that only eat meat.

Answer:

Mass the bag before and after its exposure to the solution. If diffusion occured, then there should be an increase in the bag's mass.

Explanation:

please mark brainlyest

To modify the experiment to collect quantitative data showing that water diffused into the dialysis bag, you could measure the change in the weight of the dialysis bag before and after the experiment.

Here's how you can do it: Prepare the dialysis bag and fill it with a known volume of a solution. For example, you could fill the bag with 100 mL of a sugar solution. Weigh the dialysis bag using a balance before placing it in the beaker with water.

Place the filled dialysis bag into a beaker of pure water. Make sure the dialysis bag is fully submerged in the water. Allow the setup to stand for a specific amount of time (e.g., 1 hour) to allow water to diffuse into the dialysis bag.

After the specified time, carefully remove the dialysis bag from the beaker of water and gently pat it dry with a paper towel to remove any excess water on the outside. Weigh the dialysis bag again using the same balance.

Calculate the change in weight of the dialysis bag by subtracting the initial weight from the final weight. The weight difference represents the amount of water that has diffused into the dialysis bag.

Answer:

In an ecosystem, everything is connected. All ecosystems have some form of food chain and symbiosis. This means that animals rely on each other for life. If one animal were to die then others would be negatively affected. Overall, this means that when biodiversity is lost it becomes harder for organisms to survive. For example, pandas rely on bamboo to survive. So, when it gets cut down and destroyed the pandas also suffer. Additionally, in ecosystems, a wide variety of organisms helps other living creates have more forms of survival. This shows how important biodiversity is.
