which igneous rock could physically weather to beach sand that contains the minerals pyroxene, plagioclase, feldspar, and olivine?
Answer:
gabbro
Explanation:
just took the test!
An igneous rock which could physically weather to beach sand that contains the minerals pyroxene, plagioclase, feldspar, and olivine is: Gabbro.
Weathering refers to both the chemical and physical breakdown of a rock into smaller fragments (pieces) referred to as sediments.
Generally, there are two (2) main types of weathering and these are;
1. Chemical weathering.
2. Physical weathering.
Gabbro is a coarse-grained (phaneritic), mafic intrusive type of igneous rock which physically weather to beach sand containing the following sediments or minerals:

A gene has 2 alleles, R & B, List the possible genotypes? I also need help with questions 5, 6, 7 and 8 please help! Pls look at the picture! I will mark whoever sounds best the brain! Ty!
Answer:
5.) The possible genotypes should be: RR RB BB ( if the could for the same proteins)
6.) Frequency of R: 0.5
7.)Frequency of R: 0.5
8.)Frequency of R: 0.375
Explanation:
5.) If R and B code for the different forms of the same protein then they are only a few possible out comes
6.) First calculate the total alleles in population
allele R= 40
Allele B=40
total allele = R+B= 40+40
=80
Now to find allele R frequency is:
(Total R alleles) / (Total allele in pop)
40/80=
0.5
7.)Calculate the total alleles
Alleles from for R
RR= 10
R=10x 2= 20
Multiply the value by 2 because there are 2 R alleles present in
RB=20
R=20
Number doesn't change there is only 1 R allele
Total R=20+20
=40
Alleles For B
BB=10
B=10×2
=20
Same thing here, two B alleles together so multiple by 2
RB=20
B=20
Total B= 20+20
=40
Total alleles in pop add
40+40
=80
Frequency of R
Total of R/Total Alleles
=40/80
=0.5
8.)Repeat the same thing in 7 but use different numbers
RR=10
R=10x2
=20
RB=10
R=10
Total R= 20+10
=30
13. What type of chemical hazard is a person ingesting if they eat a lot of processed foods, cured
meats, and certain types of wines?
Answer:
The correct answer is - health hazards (carcinogenic).
Explanation:
Processed foods, cured meat, and certain types of wines have a chemical present in them for increasing the life of the food and taste. This chemical is used in this food are known for their cancer-causing properties and grouped as group 1 carcinogen which comes under health hazard of type of chemical hazard.
N-nitroso-compounds (NOC) and polycyclic aromatic hydrocarbons (PAH) are the two major chemicals used in cured meat and processed food. There are many other severe health conditions also caused by ingesting a high amount of such food like diabetes, cardiovascular disease, and obesity.

How do you think molecules of food rearrange when they react with oxygen in the cells of your body?
Answer:
In cellular respiration, complex molecules containing carbon react with oxygen to produce carbon dioxide and other materials. Within individual organisms, food moves through a series of chemical reactions in which it is broken down and rearranged to form new molecules to support growth or to release energy.
Explanation:
The glucose and oxygen atoms are rearranged into carbon dioxide and water molecules during aerobic respiration. Being an exothermic chemical reaction, this process releases energy as it goes along.
What is aerobic respiration?A chemical reaction that converts carbohydrates into energy using oxygen (sugars). also known as oxidative metabolism, aerobic metabolism, and cell respiration.
During aerobic cellular respiration, glucose and oxygen combine to create ATP, which the cell can utilise.
As byproducts, carbon dioxide and water are produced. The general equation for aerobic cellular respiration is: ATP is produced when glucose and oxygen combine in cellular respiration.
During aerobic respiration, glucose and oxygen atoms are rearranged into carbon dioxide and water molecules. As it proceeds, this process releases energy since it is an exothermic chemical reaction.
Thus, molecules of food rearrange when they react with oxygen in the cells of your body.

1. What processes create igneous rocks?
2. What processes create metamorphic rocks?
3. What processes create sedimentary rocks?
Answer:
Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust.
Sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification. Erosion and weathering include the effects of wind and rain, which slowly break down large rocks into smaller ones.
Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
Explanation:
Answer:
1. Igneous rocks form when magma molten rocks cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. All magma develops underground, in the lower crust or upper mantle, because of the intense heat there.
2. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.
3. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification. Erosion and weathering include the effects of wind and rain, which slowly break down large rocks into smaller ones.

can someone help with this? the answer choices are sex-linked or autosomal for the first one, and dominant or recessive for the second
Answer:
sex-linked and recessive
Explanation:
A pedigree chart is a genetic representation that exhibits the phenotypes and genotypes for a genetically inherited trait (usually a disease or condition) in a family tree. In this case, the trait in the pedigree is recessive and linked to sex (X chromosome-linked) because it can occur only in males who receive the X chromosome for this condition from their mothers, while females can be carriers that don't have the disorder but can pass it on to offspring.

3) Select the reasons why global warming might still occur even if greenhouse-gas emissions drastically decrease.
Answer:
If the emission of greenhouse gases were stopped, global warming would still happen due to the gases that are already in the atmosphere and the constant deforestation.
Explanation:
Greenhouse gases are the biggest creators of global warming. This is because these gases cause holes in the ozone layer, which protects the planet from the sun's rays. These holes cause the sun's rays to reach the earth's surface with greater intensity, promoting global warming.
Trees are able to absorb these gases, decreasing their concentration in the atmosphere and preventing them from degrading the ozone layer. However, the constant deforestation has reduced the number of plants and the remaining amount on the planet cannot cope with the constant emission of these gases. In this case, even if the emissions of greenhouse gases were ended, the amount of these gases in the atmosphere would still be very large. Plants were slow to absorb all these gases, which would not prevent global warming from happening.

Which prezygotic mechanism most likely allowed divergence of an ancestral species into these present-day species
Answer:
The answer is "Sympatric speciation due to disruptive selection"
Explanation:
Disruptive selection is a certain type of natural choice, that aggressively favors all ends of the spectrum in a moderate community. Disruptive selection is often deduced by a phyletic prepared to change to contribute to speciation. These two species happened due to various habitats associated with extreme speciation due to various confusing choices.

5) How does a prism separate white light into the different colors that compose it?
Answer:
4 Black light uses Ultraviolet light
5 As light passes through a prism, it is bent, or refracted, by the angles and plane faces of the prism and each wavelength of light is refracted by a slightly different amount. ... As a result, all of the colors in the white light of the sun separate into the individual bands of color characteristic of a rainbow.
