3. If a daughter has an X-linked recessive disorder, such as color-blindness, she inherited the
trait from
a. her mother
b. her father
c. both parents
d. neither parents
Answer:
She inherited the trait from C: both parents.
Explanation:
The daughter, being female, has the chromosomes XX. Since the disorder is recessive, both of the chromosomes need to have the disorder's allele in order for it to activate. The daughter's chromosomes can be labeled as X(c)X(c); where the c stands for the color-blindness allele. She needs one X chromosome from the father, and one X chromosome from the mother. Both of these chromosomes contained the (c) allele, as said before, so the mother has one X(c) and the father has one X(c). This means that she inherited the trait from both parents. The final answer is C.
cross a heterozygous individual with a homozygous recessive one determine the genotype ratio and phenotype ratio of their offspring
Answer:
Let's have our alleles be J = dominant, j = recessive. And for fun let's make the dominant phenotype black coat, the recessive brown coat.
Heterozygous x homozygous recessive
= Jj x jj
Punnett square:
J j
j Jj jj
j Jj jj
Genotypic ratio: 2 Jj : 2 jj, or a one-to-one ratio of Jj to jj.
Phenotypic ratio: 2 black : 2 brown, or a one-to-one ratio of black to brown.

Can the number of protons in an element ever change?
Answer:
An elements atomic number will never change
Explanation:
That is because the atomic number is its "identity.". The atomic number is the number of protons that is contained in the nucleus, if you add a proton you change the element. Therefore, an elements atomic number will never change. Atomic mass, however, can change and we call these isotopes.

A. altitude, insolation, ocean currents, soil type
B. insolation, mountain ranges, ocean currents, soil type
C. insolation, latitude, mean June temperature, ocean currents
D. global winds, insolation, large bodies of water, ocean currents
Answer:
Global winds, insolation, insolation, large bodies of water, ocean currents.
Explanation:
Climate is the atmospheric condition of a place at a time such as temperature and rainfall . global winds, insolation, large bodies of water, ocean currents consist of four factors that play a role in determining climate. Insolation or solar energy determine climate of an area. Rays of sunlight hit the Earth and area near the equator which in one way or the order increase the temperature of an area.
lakes, oceans, and streams play a vital role in climate processes by serving as reservoirs for water, which can evaporate from the surface to fall later as rain or snow.
Bodies of water also reduce changes in temperature of surronding land areas .They make sure high temperature Don't get high and low temperature Don't reduce to low.
Ocean currents which move water from one place to another affect the climate of a place.

Genes often contain large regions that are NOT included in translation. These sections are called
Answer:
Non-coding regions
Explanation:
Genes are segments of DNA that undergoes expression into functional products called PROTEIN. However, these genes contain both the parts or regions that encode proteins and those that don't. The part that encodes proteins are called coding sequences while those that don't encode proteins, which make up the bulk of the gene are called Non-coding regions.
When a gene undergoes expression, it is first transcibed into an RNA molecule, then translated into proteins. The coding regions of the gene will be translated while the non-coding regions will be spliced out
(introns) post-transcriptionn or be used to make RNA.

Which of the following statements best describes the formation of volcanoes?
A.
At a transform plate boundary, the crusts slide against each other to form magma by frictional heat.
B.
At a convergent plate boundary, the oceanic crust is pulled beneath the continental crust, where magma forms and moves upward.
C.
At a divergent plate boundary, the pressure of seawater rushing into the oceanic crust rift creates a volcano.
D.
At a convergent plate boundary, the continental crust collides with another continental crust to form volcanoes.
Answer:
B). At a convergent plate boundary, the oceanic crust is pulled beneath the continental crust, where magma forms and moves upward.
Explanation:
Volcano is described as the fissure in the crust of the earth through which the molten rock, lava, or hot gases are allowed to escape from this chamber. The second option most appropriately states that 'the oceanic crust is pulled beneath the continental crust at a convergent plate boundary where the formation of magma takes place and makes it to the surface(through eruption in the form of lava).' The process can have both the creative as well as destructive impacts as it brings a lot of useful minerals that makes the soil rich and fertile while on the other hand, the ash is fatal for the environment. Thus, option B is the correct answer.
The statement which best describes the formation of volcanoes is: B. At a convergent plate boundary, the oceanic crust is pulled beneath the continental crust, where magma forms and moves upward.
A volcano can be defined as a mountain or hill that has a large circular or conical hole at the top through which volcanic ash, rock fragments, gases, dust, hot lava, steam etc., are expelled from the vent of a planetary-mass object, either at regular intervals or continuously.
A convergent plate boundary refers to a boundary where two (2) plates move towards each other, thereby, resulting in subduction or collision.
As a result of the oceanic crust being pulled beneath the continental crust at a convergent plate boundary, molten magma are formed and then moved upward as volcanoes.
In conclusion, the collision between two (2) plates as a result of subduction causes an oceanic crust to be forced underneath the mantle, thereby, forming volcanoes.

Two mammals with the genotype CcEr are crossed. 'C' produces a thick coat of fur and is dominant to 'c', which produces a thin fur coat. 'E' produces brown eyes and is dominant to 'e', which produces red eyes. What fraction of offspring would you except to have both a thin fur coat and brown eyes?
Answer:
3/16 of the kids would be expected to have a thin fur coat and brown eyes.
Explanation:
Use the punnet square method.
The fraction of offspring would you except to have both a thin fur coat and brown eyes is 3/16.
What is Punnett Square?A Punnett square is defined as a helpful tool to help predict variations and probabilities which may come from cross breeding in which plants, animals, even humans interbreed with each other. This is used by biologists for determining the probability of an offspring having a particular genotype.
The information given above is dizygotic cross which is a cross between two individuals having two observed traits which are controlled by two different genes. In this case, the two traits are thick and thin fur coats (C and c, respectively) and brown and red eyes (E and e, respectively).
The expected phenotypic ratio of crossing heterozygous would be 9:3:3:1 which produces
9 Thick fur coat and Brown eyes mammals (9/16 fraction)
3 Thick fur coat and Red eyes mammals (3/16 fraction)
3 Thin fur coat and brown eyes mammals (3/16 fraction)
1 Thin fur coat and red eyes mammals (1/16 fraction)
Thus, the fraction of offspring would you except to have both a thin fur coat and brown eyes is 3/16.

Giraffes, camels, and horses share some traits, although they vary in other traits. Which statement accurately describes the evolution of these species?
Answer:
If there are options for this question, I couldn't find them online but I can tell you that one statement that describes the evolution of these species is that each of them shared an ancient ancestor.
Explanation:
The ancient common ancestor that these species share is that animal, in this case, from which all species descend.
It is the only species of living being that has evolved over the years and its original traits have varied, which led to the creation of all these species. That is why some of those traits will still be shared by them, while others, due to evolution, will not.
That is why we could say that these animals belong "to the same family" since they all come from the same ancestor.

Which word best describes the nature of predator-prey dynamics in stable communities?
Answer:
Cyclic
Explanation:
It is cyclic because as the number of predators increase in the ecosystem, the number of preys decreases with time. This decrease in preys means lesser food resources for the predators which then decreases the population of the preys. As the predators decrease the number of preys starts to recover and increase in population.
The cycle goes on and on which makes it a cyclic relationship in the nature of predator-prey dynamics in stable communities
The word that described the nature of predator-prey dynamics in stable communities is Cyclic.
What is Cyclic?It should be cyclic since the no of predators should be raised in the ecosystem also the number of prey should be decreased along with time. Here the reduction of prey represents that there are fewer food resources due to which it reduced the preys population. Also, when the predators reduced the no of preys so it begins to recover due to which the population is increased.
