How is earths surface most likely to change as the water freezes and expands on a mountain side over time?
Erosion will cause the ice to crack the rock
Physical weathering will cause the ice to crack the rock
Chemical weathering will cause the water to dissolve the rock
Disposition will cause the water to break the rock into sediment
The earths surface most likely to change as the water freezes and expands on a mountain side over time because Physical weathering will cause the ice to crack the rock.
What is soil erosion?Erosion is nothing more than the displacement of land that happens from one place to another. In nature, the erosive process occurs by the natural action of the sun, winds and, mainly, rainwater.
It is a natural procedure, however, human action contributes to its intensification. The uncontrolled erosion process causes great damage to the environment, as it acts on the wear of the soil, makes it difficult to maintain species of animals and plants, in addition to disrupting human activities.
In this case, Erosion involves the wearing down, transport and deposition of soils and rock particles. So, the Physical weathering will cause the ice to crack the rock.

Cual de estos no se podria observar en un microscopio optico crestas mitocondriales, poros de la membrana nuclear, cromosomas de una celula animal condensados durante la mitosis, las dos capas lipidas que forman la membrana plasmatica
Answer:
Crestas mitocondriales, poros de la membrana nuclear y las capas lipídicas que forman la membrana plasmática no son visibles al microscopio óptico.
Explanation:
El límite de resolución de un microscopio óptico es de, aproximadamente, de 0,2 μm (es decir 10⁻⁶ m). Es decir, que en un microscopio óptico sólo podrán verse células y estructuras celulares mayores a 0,2 μm, y en algunos casos serán visibles sólo con tinciones especiales.
Por ende, entre las cuatro estructuras que se nos presentan en el problema sólo los cromosomas de una celula animal condensados durante la mitosis pueden verse al microscopio óptico.
Tanto las crestas mitocondriales como los poros de la membrana nuclear y las capas lipídicas que forman la membrana son estructuras muy pequeñas y visibles solamente al microscopio electrónico.

I’m at the beginning of earth’s timeline, but at the end of life’s start. I was there when a T-rex began, but in the middle of it’s asteroid end. What am I?
I believee it's the Cretaceous Period?
All of the dinosaur periods are at the start of Earth's timeline, and "the end of life's start" suggests the end of dinosaurs, meaning, when the asteroid hit. So it's probably one of the Mesozoic periods.
The T-rex first appeared in the Cretaceous Period, and the asteroid hit somewhat during middle of the Cretaceous Period.

Red-green color blindness is an X-linked recessive disorder.
A Punnett square is shown. The columns are labeled X Upper B and Upper Y. The rows are labeled x Upper B and x b.
What is the probability of the offspring having red-green color blindness for the cross that is represented by the Punnett square?
0 percent
25 percent
50 percent
75 percent
Answer: 25%
Explanation: This is the correct answer on Edge 2020 (just took the unit test review and made a 100%) ^-^.
X-linked recessive disorder refers to the genetic condition in which mutations or errors are associated with the gene are present on the X chromosome. The male will be affected by the disorder, while the females can be carriers.
In the given Punnett square, there is a 25% chance that the offspring can be -red-green color blind.
Red-green color blindness in people refers to the difficulty in distinguishing the colors like red, green, orange, and yellow. People with color blind have a normal life and there is no proper cure for the condition.
Thus, the percentage of the offspring that will be red-green color blind is 25%.

how is the plant able to obtain each ingredient
Answer:
light enters a plant through its leaves O2 enters the plant through the stomata's or open pores
and water enters through the roots then up the stem to the tubes to leave
Explanation:
hopefully this helps
The Plants able to obtain each ingredients from the atmosphere. the light from the sunlight, [tex]CO2[/tex] from the stomata, and the water from the roots.
Stomata allow plants to absorb [tex]CO2[/tex] from the atmosphere. Water is taken from the earth by plants and transmitted to their leaves via their roots. The only source of light that the chlorophyll and other green parts of the plant absorb is sunlight.
Plants use sunlight, water, and carbon dioxide to perform photosynthesis.
They produce Chlorophyll, the pigment that makes plants green, by using stored carbon, hydrogen from water, and magnesium from the soil. They make Adenosine triphosphate, which is vital in energy transfer, by combining phosphorus, oxygen, and carbon.
Thus, Plants take nutrient from the atmosphere . light from the sunlight, [tex]CO2[/tex] from the stomata, and the water from the roots.

O The amount of nutrients available in a soil
O A measure of soil quality which stays constant throughout a growing season
O The quality or ability of a soil to provide nutrients to plants
Answer:
O the amount of nutrients available in soil
Explanation:
good answer
Measure of soil quality which stays constant throughout a growing season is best describes the soil fertility.
What do you mean by soil fertility?Soil fertility refers to the ability of soil to sustain agricultural plant growth, i.e. to provide plant habitat and result in sustained and consistent yields of high quality.
A fertile soil will contain all the major nutrients for basic plant nutrition (e.g., nitrogen, phosphorus, and potassium), as well as other nutrients needed in smaller quantities, e.g., calcium, magnesium, sulfur, iron.
The following properties contribute to soil fertility in most situations: Sufficient soil depth for adequate root growth and water retention; Good internal drainage, allowing sufficient aeration for optimal root growth.
