This is where magma is found and created

Convection currents in the mantle causes the tectonic plates to move

Explanation:

Answer:

It depends the substance

Explanation:

Physical properties of a substance like Color, odor, density, melting temperature, boiling temperature can determine the purity of a substance.

The matter can be classified as pure substances and mixtures.

Pure substances are made up same kind of particle and have a constant structure.

Pure substances can be up two types elements and compounds.

An element which consists of only one type atom, so it can not be broken down by using physical or chemical method. Elements are metals, non-metals or metalloids.

Compounds are the pure substances if two or more same type of elements are combined chemically, but these can be broken down into separate elements by treating them with chemical methods.

Answer:

- 002 .45 2.71 3.84 6.64 10.83

2 0.02 0.21 1.39 4.61 5.99 9.21 13.82

3 0.11 0.58 2.37 6.25 7.81 11.35 16.25

4 0.30 1.03 3.36 7.78 9.49 13.28 18.

Explanation:

From the test cross and X² test, I assume the individual is dihybrid and genes are in separate chromosomes. 1)25 aB. 2)X²=2. 3)P₀.₀₅=7.81. 4)Accept the model.

A test cross is a cross we use to determine the genotype of individuals whose phenotype we already recognize.

The cross occurs between the individual of an unknown genotype and a recessive h0m0zygous individual. We want to know if the unknown  genotype is heter0zyg0us or h0m0zyg0us dominant for a single gene.

Considering only one gene involved in the cross,

The phenotypic and genotypic ratio is 1:1

Considering two genes that assort independently are test crossed,

If more than one gene are involved, we can also determine if these genes assort independently, or if they are linked.

When phenotypes appear in different proportions than the expected ones, we can assume that these genes are linked.

However, the difference between the observed and the expected data can be by random chance. This means that genes could assort independently, but by chance, the observed ratios vary from the expected ones.

To analyze these situations and determine is the difference is by chance or because genes are linked, we need to perform a chi-square test.

---------------------

Now, let us answer the question.

Available data:

Test cross

F1 = 100 individuals

1)  What expected number would you use for the aB class?

To answer this question, we assume genes assort independently, so if this is the case, genotypic ratio should be 1:1:1:1, or 25% AB : 25% aB : 25% Ab : 25% ab

100% ------------- 100 individuals

25% -------------X = (25% x 100) / 100% = 25 individuals AB

25% -------------X = (25% x 100) / 100% = 25 individuals aB

25% -------------X = (25% x 100) / 100% = 25 individuals Ab

25% -------------X = (25% x 100) / 100% = 25 individuals ab

So, accordig to our calculations, the expected number for the aB class is 25 individuals.

----------------------------

2) Calculate the chi-square value.

Model: dihybrid test cross of two genes on separate chromosomes -assort independently-.

                             AB         Ab          aB         ab      

Observed, O        22          28          29         21

Expected, E          25          25         25        25    

(O-E)² / E             0.36      0.36       0.64      0.64

X² =  Σ(Obs-Exp)²/Exp =  0.36 + 0.36 + 0.64 + 0.64 = 2

X² = 2

The chi-square value is X² = 2

-------------------------

3) Determine the probability that the model would give the observed data.

Freedom degrees = n - 1          Where n is the number of classes ⇒ 4.

Freedom degrees = 4 - 1 = 3

Significance level = 0.05

Conventionally, we use 0.05 = 5% as the significance level.

Critical value (table value) = 7.81

Considering a significance level of 0.05 and 3 freedom degrees, the critical value equals 7.81.

--------------------------

4) would you accept or reject your model?

X² < P₀.₀₅  ⇒ 2 < 7.81

p value is greater than X², so there is not enough evidence to reject the null hypothesis. The ungenotype might be a dihybrid, and there might be independent assortment.

I would accept the model.

Crossing over shuffles alleles on non-sister chromatids of homologous chromosomes.

At the prophase I stage of meiosis, homologous chromosomes synapsed to form a four-chromatid structure known as tetrad. Exchange of chromosomal segments between non-sister chromatids of the tetrad then takes place, a process that results in the reshuffling of genes or alleles on the non-sister chromatids.

In order words, is an agreed way of doing things by a group of scientists with similar interests.

In relation to the question, there is a scientific convention with respect to experiments and the presentation of scientific studies.

Explanation:

Coronary sinus, right atrium is part of the circulatory system that consist of arteries, arterioles, veins, capillaries that move blood to the heart tissue and remove waste from the blood.

The cardiac veins return deoxygenated blood to the right atrium and it them moves to the right ventricle then to the heart where it becomes oxygenated

The coronary sinus received drain blood from ventricles veins, it then moves the deoxygenated blood to the right atrium which it transfer or move to the right ventricle (through the tricuspid valve which in turn move the blood to the pulmonary artery for pulmonary veins.

J = F∆t

is a vector quantity (since force is a vector and time is a scalar).

Impulse-Momentum Theorem

The impulse-momentum theorem states that the change in momentum of an object equals the impulse applied to it.

J = ∆p

If mass is constant, then…

F∆t = m∆v

If mass is changing, then…

F dt = m dv + v dm

The impulse-momentum theorem is logically equivalent to Newton's second law of motion (the force

Answer:The timing of the cricket's depends on the temperature of the box

so the answer should be

timing of the cricket's chirps

Explanation:Hi!

There are a few types of variables in these types of experiments. They are independent, dependent, and controlled.

The independent is the one changed by the scientist, or in this case, the temperature. The controlled is the things that remain constant through every case, and the dependent is what is being observed, seeing if it changes through the altercation of the independent variable.

In this case, what is being observed is the timing of a cricket's chirps, because it is being watched whether or not temperature affects it.

Therefore, your answer is the third choice, or the timing of the cricket's chirps.

Answer:

b. False

Explanation:

A scientific theory must have strong support from testable facts that are confirmed (or rejected) by observational and/or experimental procedures. The scientific method is a rigorous process that consists of arising a conjecture (hypothesis) which can be subsequently used to make predictions from its logical consequences, and finally to obtain information from empirical observations/experiments in order to obtain a conclusion about the veracity of the scientific claims (i.e., a hypothesis must be testable). In consequence, a scientific theory can not be based only on 'light' conjectures, but trustworthy observational data from the real world.
