Which is true of a positive feedback loop?
A. It causes products of a reaction to increase the reaction, moving away from equilibrium.
B. It only occurs in plants.
C. It helps the characteristic stay at equilibrium.

Answers

Answer 1

 Answer: A. It causes products of a reaction to increase the reaction, moving away from equilibrium.

 Explanation: In a natural system, a positive feedback loop magnifies or worsens the impacts of a little disturbance or change, which then cause the system to react. Each input and output in a biological system is a result of and contributes to a specific occurrence. A biological phenomenon known as a feedback loop occurs when a system's output either amplifies the system (positive feedback) or suppresses the system (negative feedback). The ability of feedback loops to help living things maintain homeostasis makes them crucial. The mechanism known as homeostasis helps us maintain a reasonably stable internal environment that is neither too hot nor too cold, neither too hungry nor too sleepy. Depending on the type of organism and the environment it lives in, different levels of energy are required to keep an organism in a state of homeostasis.

Answer:

The answer is "using wind energy to generate electricity".

Explanation:

The Wind turbines may not emit water or sulfur compounds (with rare exceptions) and require no water as a coolant. The cost of power produced from energy sources may also be reduced by windmills, which will result in lower overall air quality and hosing pollution, that's why Utilizing wind energy for energy production decreases human greenhouse gas sources.

A panda (herbivore) eats bamboo shoots and leaves, while a lion (carnivore) preys on other animals.A bear (omnivore) eats both plants and animals, while a vulture (scavenger) feeds on the remains of dead animals.What are consumers?

In an ecosystem, consumers are organisms that obtain their energy and nutrients by feeding on other organisms. They are a vital part of the food chain, and they come in different sizes and types.

Consumers can be classified into several categories based on what they eat. For example:

Herbivores: These are animals that consume only plants for their food. Examples include rabbits, cows, and giraffes.

Carnivores: These are animals that consume other animals for their food. Examples include lions, tigers, and sharks.

Omnivores: These are animals that eat both plants and animals. Examples include humans, bears, and raccoons.

Scavengers: These are animals that feed on the remains of dead organisms. Examples include vultures, hyenas, and some types of beetles.

Consumers play an important role in an ecosystem, as they help to transfer energy and nutrients from one level of the food chain to another. They are an integral part of maintaining the balance and stability of an ecosystem.

Answers

Answer:

Probability is a method for determining the likelihood of something uncertain occurring. If you flip a coin, you do not know whether it will be heads or tails, but probability can tell you that there is a 1/2 chance of either happening. Probability is a method used to predict the likelihoods of uncertain outcomes. It is important for the field of genetics because it is used to reveal traits that are hidden in the genome by dominant alleles. Probability allows scientists and doctors to calculate the chance that offspring will inherit certain traits, including some genetic diseases like cystic fibrosis and Huntington's disease.
