Why do leaves change color in the fall?
- their roots stop absorbing minerals
- their roots stop absorbing water
- they stop photosynthesis
- they stop making chlorophyll

Answers

Answer 1

The correct answer is D. They stop making chlorophyll

Explanation:

The regular green color in leaves is mainly the result of chlorophyll, which is essential for photosynthesis. This substance stops being produced by plants during the fall, and this causes leaves to lose their characteristic color. Additionally, this process is the result of shorter days, and therefore fewer daylight hours, which reduces or stops the production of chlorophyll. At the same time, the carotenoids which are red, yellow, and orange pigments begin to be visible. Thus, the reason leaves change color in the fall is that they stop making chlorophyll.

Answer 2

Answer:

The answer you are looking for is they stop making chlorophyll

Explanation:

Because yes!! Also I hope you have a wonderful wonderful day!! :D

what is the purpose of the lab? red and light red walking beans​

Answers

The purpose of the laboratory experiment "red and light red walking beans​" is that the red light will make the beans invisible to other organisms and animals, which increase the population and survival rate of the beans.

What is a laboratory experiment?

Laboratory experiments are described as research methodologies  by which researchers create controllable environments to test hypotheses.

The hypothesis about the effect of the red light on the population of light red walking beans is that  If red light is shined on a population of red walking beans then they would not be as red as when started because they would need light to survive.

The red light is present but they will  not reflect it until they need it to survive.

Answers

Diagram A: Passive transport

Diagram B: Equilibrium

Diagram C: Active transport

Diagram D: Equilibrium

Diagram E: Active transport

Diagram F: Passive transport

Passive transport: The molecules go through the membrane from a place of higher concentration to a place of lower concentration according to the second law of thermodynamics, without the need to consume energy, until the system reaches the equilibrium.

Active transport: The molecules go through the membrane against the concentration gradient, with an energy cost to the cell.

Equilibrium: It is not static but dynamic, so some molecules may go through the membrane in both directions, but the result will be the same concentration in both sides of it.

Which can be excluded from the list of events caused by the flow of thermal energy inside the Earth?(1 point)volcanic eruptionsthunderstormsearthquakesvalley formations

Answers

Let's explore how each of the options is formed.

Volcanic eruptions: It is when a volcano explodes due to magma build-up in the magma chamber. Lava, pyroclastic materials, and magma flow out of the volcano. It is related to the thermal energy inside the Earth because the heat is released to the surface of the Earth.

Thunderstorms: It is formed when three components: unstable weather conditions, uprising cold air, and enough moisture are present in the area. Based on the criteria for thunderstorms to form, it is not related to the flow of thermal energy inside the Earth.

Earthquakes: It is a phenomenon when two tectonic plates collide, slide, or crush one another, or when a volcano is about to erupt. It is a sudden and violent shaking of the ground. It is related to the flow of thermal energy inside the Earth since the pressure and temperature of the collision of the tectonic plates result in the formation of geothermal energy.

Valley Formation: A valley is a land formation wherein a low area is found between two hills or mountains. It is formed by erosion and gradual weathering of land by the wind and water. In the case of Hawaii volcanoes, its valleys were formed on the weathering of the slopes between the volcanoes. It is related to the flow of thermal energy inside the Earth.

Answers

Answer:

Through the process of natural selection, sea urchins have developed spines that serve as a defense mechanism against predators and a means of anchoring themselves in turbulent waters. This adaptation allows them to better survive in their environment, with individuals possessing longer or stronger spines being more likely to pass on their genes to the next generation. As a result, the population of sea urchins gradually becomes better adapted to their surroundings, demonstrating the power of natural selection in shaping the evolution of species.

Devise a serial dilution scheme to prepare 1/10, 1/30 and 1/90 dilutions of a disinfectant.

Answers

Serial dilution is a simple process that involves repeated dilution of a stock solution to obtain solutions of different concentrations. This can be used to prepare a series of dilutions, each of which is one-tenth or one-third of the preceding concentration.

The following is an example of a serial dilution scheme to prepare 1/10, 1/30, and 1/90 dilutions of a disinfectant:Step 1: Obtain 3 sterile tubes labeled A, B, and C. Step 2: Transfer 1 mL of the disinfectant to tube .

A containing 9 mL of sterile water. This is the 1/10 dilution.Step 3: Transfer 3 mL of the 1/10 dilution to tube B containing 7 mL of sterile water. This is the 1/30 dilution. Step 4: Transfer 3 mL of the 1/30 dilution to tube C containing 7 mL of sterile water. This is the 1/90 dilution.

Answers

Tabletop

A tabletop exercise is a type of incident response plan evaluation that is typically conducted in an informal and stress-free environment. It is a discussion-based activity that takes place on a monthly basis and involves a scenario that is relevant to the organization’s incident response plan. During the exercise, the incident response team and other stakeholders use the scenario to test the organization’s readiness and response capabilities. This can include evaluating the team’s knowledge and understanding of the response plan, determining if the plan is complete and up to date, and identifying any gaps or weaknesses.

The tabletop exercise is an effective way to evaluate an incident response plan because it allows for an open dialogue between the team members and stakeholders. It also allows the team to identify any areas of ambiguity or confusion, as well as any potential issues or areas of improvement. By using a scenario-based approach, the team can work through the entire incident response process without any real-world consequences.
