A student was asked to prepare a model of the rock cycle as it moves matter slowly through the Earth. The student creates a model,
as shown here. In order to revise the model, how should the lettered components be modified in order to create an accurate model?
Select all choices that apply
es )
A)
Letter A should represent igneous rock that is extruded from magma,
B)
Letters A and B should both be igneous rock, which is found near the
Earth's surface.
C)
Letters and B should be sedimentary rock, which is found under layers of
other materials
D)
Letter C should represent metamorphic rock which changes composition
under heat and pressure.
E)
Letter B should represent sedimentary rock that is buried by layers of sand
and deposited material.
Answers
Answer:
A) Letter A should represent igneous rock that is extruded from magma.
D) Letter C should represent metamorphic rock which changes composition under heat and pressure.
E) Letter B should represent sedimentary rock that is buried by layers of sand and deposited material.
Explanation:
Igneous rock comes from magma/lava. Sedimentary rock is buried as layers are deposited. The metamorphic rock is formed when one type of rock changes from one form to another. The single letter options are all right here.
The Rock Cycle is related to transformation of three basic Rock types into one another through the Plate tectonic activity, along with weathering and erosional processes. Hence Correct options are A, D, and E.
The Rock CycleIt is a phenomenon through which three basic types of Rock transformed into one another. These three types of Rock are Igneous, Metamorphic, and Sedimentary rocks.
Therefore, to prepare a model which shows Rock Cycle, student need to have three types of Rock as mentioned in option A, D, and E.
A) Letter A should represent igneous rock that is extruded from magma.
D) Letter C should represent metamorphic rock which changes composition under heat and pressure.
E) Letter B should represent sedimentary rock that is buried by layers of sand and deposited material.

What type of chemical bond exists between two water molecules
Answers
Hydrogen bonds, type of chemical bond exists between two water molecules.
What is a chemical bond?A chemical bond is what binds atoms in molecules together. Electrical forces between positive charge atomic nuclei and negative-charged electrons form bonds. A chemical bond is a long-lasting attraction between ions or atoms that allows molecules and crystals to form.
Hydrogen bonds arise between neighboring water molecules' hydrogen and oxygen atoms. A hydrogen bond is formed by the attraction of individual water molecules. A water molecule is made up of two hydrogen and oxygen atoms atom, with one partly positive hydrogen atom connected to a more highly electronegative atom.

Answer:
Physical adaptations do not develop during an individual animal's life, but over many generations. The shape of a bird's beak, the color of a mammal's fur, the thickness or thinness of the fur, the shape of the nose or ears are all examples of physical adaptations which help different animals survive.
The organism in the photo is a daphnia, or water flea. Daphnia are tiny aquatic organisms that live in most freshwater habitats. Adults range from less than 1 to 5 mm in length. They are good swimmers and eat mostly algae. Daphnia become mature at 5 to 10 days, and an adult female can produce up to 100 eggs every 3 or 4 days during its 2-month life span. When harmful algae rapidly increase in the daphnia environment, daphnia can develop adaptations to tolerate the negative effects of the algae within 10 years. What characteristic of the daphnia allows the population to adapt to environmental change
Answers
Answer:
The characteristic of daphnia which allows the population to adapt to the environmental change is the short generation time.
Explanation:
As evident from the text, the maturity comes in 5 to 10 days and they reproduce for the next 2 months at a rate of 100 eggs every 3/4 days. This is a short generation time which makes the evolutionary changes easy and less time-consuming to incorporate.
Is race a biological characteristic determined by our genes?
Answers
Answer:
No, they are not. The concept of human races appears to be solidly grounded in present-day biology and our evolutionary history. But if you asked that conference of geneticists to give you a genetic definition of race, they wouldn’t be able to do it. Human races are not natural genetic groups; they are socially constructed categories. Genes certainly reflect geography, but unlike geography, human genetic differences don't fall along obvious natural boundaries that might define races.
If DNA code consists of only four nitrogenous bases, how can it produce so much variety among
organisms of the same species?
Answers
Explanation:
I tnought this will help you
If DNA code consists of only four nitrogenous bases, still it produces so much variety among organisms of the same species with the help of Codons and amino acids sequences.
What do you mean by Nitrogenous bases?Nitrogenous bases may be defined as a molecule that contains nitrogen and possesses the chemical properties of a base. The nitrogenous bases that are found in DNA are Adenine (A), Guanine (G), Thymine (T). and Cytosine (C). Uracil (U) is present instead of Thymine in RNA.
There is a total of 4 nitrogenous bases that are found in DNA and RNA. Each codon codes with the help of three nitrogenous bases. So, total variations = [tex]4^3[/tex] = 64.
But there are only 20 amino acids that are commonly known. Some codons are stop codons, they do not code for any amino acids. While some codons code for the same amino acids.
Therefore, If DNA code consists of only four nitrogenous bases, still it produces so much variety among organisms of the same species with the help of Codons and amino acids sequences.

Which statements about geocentric model and heliocentric model are true? Select the two correct answers.
A. They both are models of the solar system.
B. They both show the position of Earth relative to the Sun.
C. They both show Earth at the center of the solar system.
D. They both show the Sun at the center of the solar system.
Answers
Answer: Your correct answer would be both A & B.
Explanation: A is the correct answer because both of these models are in fact models of our solar system. The geocentric model had Earth at the center of the solar system with all the other planets and sun rotating around us. The heliocentric model is the accepted model of our solar system today with the sun at the center and planets rotating in slightly elliptical fashions around it due to gravitational pull. B is also correct because as I just explained, both models position Earth in relativity to the sun though both models vary greatly. The aim of both of these models was to specify where Earth was exactly in the solar system. I hope this has been of use to you! Please do not hesitate to ask if you have other questions :)
The two correct statements about the geocentric and the heliocentric model are:
They both show the position of Earth relative to the Sun. They both are models of the solar system.The geocentric model
The geocentric model has the assumption that the earth is at the center of the universe. The sun and the planets are said to revolve around the earth in this model
The heliocentric model:
The heliocentric model has the assumption that the sun is at the center of the universe. The earth and the planets revolve around it.

If there weren't alleles for different traits, but rather only one version of a gene for different traits, how would humans be different?
Answers
Answer:
Humans would look exactly alike
Explanation:
An allele which is a variation of a gene which expresses a particular trait(Phenotype).
For example, if humans have a gene for eye color but has different alleles for the color being black or brown for example, their phenotypes are different since the alleles are different.
But, if the alleles for the eye color are all the same, the eye color and every other phenotype would be the same. So, there would be no variations in eye color, height, color of skin etc. So, all humans would thus look alike having one set of genes for the different traits.
