Can someone give me 4 examples of physical weathering
valkas [14]
Yes, sure!

1) Moving Water - Water, when running for a long period of time, can actually start to weather rocks.

2) <span>Ice wedging - Yep, this can cause rocks to weather as well. Water, when being constantly frozen and unfrozen weathers the rock due to the fact that water is able to expand.
</span>
3) Plant Roots - Ah, these little nutrient grabbers can certainly weather rocks over periods of time.

4) Winds - Winds can certainly physically weather the rocks, and it's probably the most common way they do.


<span>P.S. If this answer helped you, please, make sure to say "Thanks" just below my answer. It will help me a lot</span>

What is responsible for the breakdown and absorption of nutrients
Maksim231197 [3]
Stomach

In the stomach, enzymes break down food such as carbohydrates, protein and fats, so that nutrients can be absorbed farther down the GI tract, according to the National Digestive Disease Information Clearinghouse. The stomach mixes and churns foods to slowly release into the small intestine. Liquids empty the quickest, in one to two hours, and solid food takes about two to three hours to transit out of the stomach.

Why is a system’s work output limited?
netineya [11]
<span>The correct answer is Energy is lost as heat in each stage, causing the amount of energy available to decrease with each stage. This means that eventually energy is bound to run out. Simplest example is a car for example, as long as it works there's less and less fuel, and eventually the energy runs out, or in this case the fuel.</span>

Anit [1.1K]

Answer:

Dark colored moth

Explanation:

Moths either dark or light live on the bark of the trees. During industrial revolution in England, excessive pollution caused the darkening of bark of trees. Due to this environmental change, some of the light colored moths evolved and turned into dark colored moths. Both bark and moth being dark in color, made the moths untraceable by their predators. While the light colored moths on dark trees were easily recognizable by their predators.

Hence, the dark colored moths possess high fitness.

Which best describes the factors that affect a phenotype?
Gnoma [55]
Genotype and the environment both can affect a phenotype.
Phenotype= a physical feature resulting from a certain genotype.

For example,  let's say a person born with a genotype pp has the phenotype: pale skin. However, if they live in a sunny environment, then the melanin in their skin will increase over time changing their phenotype to tan skin. Does that make sense as to how both factors can impact phenotype?
