Melanoma is often caused by ultraviolet radiation that is absorbed by the skin. Suggest an explanation for the differences in the figures for men and women.

Answer:

The correct answer would be -

parent 1: GG

parent 2: gg

offspring: Gg

Explanation:

Let assume the dominant allele of the dragon scale is represent by G and the recessive allele that expressed in brown is represented by g. As it is given that offspring by mating is expressing this trait as a speckled pattern of both alleles brown and green which means it shows codominance where both alleles expressed together in offspring if present in heterozygous condition.

So, the cross between GG and gg will result in a heterozygous combination to produce offspring with a speckled pattern of brown and green scales.

The correct answer would be -

parent 1: GG

parent 2: gg

offspring: Gg

Simple diffusion does not require energy from ATP. Facilitated diffusion may or may not require energy from ATP. In simple diffusion, the molecules can pass only in the direction of concentration gradient. In facilitated diffusion, the molecules can pass both in direction and opposite of the concentration gradient.

Explanation:

Answer:

asthenosphere

Explanation: The asthenosphere is a part of the upper mantle just below the lithosphere that is involved in plate tectonic movement

Active transport is the transport of molecules from the region of lower concentration to the region of higher concentration against the concentration gradient.

Energy is required in this type of movement which is provided in the currency of energy i.e. ATP

_________________________________________________________

Q. Why is Energy Required?

A. Energy is required in this type of movement, because the molecules are moving from less crowded region of the molecules to the more crowded region of the molecule, so the energy is required to get into the crowdy region the molecules require energy to kind of PUSH the molecules and get into that region.

_________________________________________________________

Q. Where does ATP come from?

A. Free energy obtained from hydrolysis of ATP is used for the movement of the solutes against the concentration gradient across the plasma. The transmembrane protein which is also called pump is used in this process, The transmembrane protein is the type of integral protein which provides gateways to permit the transport of specific substances across the membrane.

Answer:

A change in wind direction cause the air to spiral. Then, warm humid air rises up in the inside of the tornado while cold dry air goes down. These things cause the spinning air currents inside the tornado.

hope this helps!

Suddenly, air pressure changes that significantly cause rapid air movement which ultimately leads a tornado to form. Thus, the correct option is D.

A Tornado may be characterized as a type of natural phenomenon that significantly involves vehemently rotating columns of air touching the ground, usually attached to the base of a thunderstorm.

Tornadoes are generally considered nature's most violent storms. They are generated by powerful thunderstorms and have the ability to cause fatalities and devastate a neighborhood in seconds.

Winds of a tornado may reach 300 miles per hour. Apart from this, a tornado may evolve within a cyclone and form due to the influence of low pressure in the eye of a cyclone.

Therefore, suddenly, air pressure changes that significantly cause rapid air movement which ultimately leads a tornado to form. Thus, the correct option is D.

Answer: pathway intermediates are prevented from entering alternative metabolic pathways

Explanation: the clustering of enzymes in a metabolic pathway ensures that the product of one enzyme is efficiently transferred to the next enzyme in the pathway. So, the clustering prevents pathway intermediates from being diverted into alternative metabolic pathways.

The statement that best describes the most likely result of this clustering of enzymes is as follows:

Thus, the correct option for this question is A.

Enzymes may be defined as biocatalysts that increase the rate of a chemical reaction without being altered in the complete process. It is thought that all cellular reactions or processes are mediated by enzymes.

According to the context of this question, the process of assembling or clustering enzymes in any metabolic pathway makes sure that the outcome of one enzyme is operating as the reactant of the next enzyme in the same metabolic pathway.

So, the process of clustering effectively restricts the formation of intermediates and the regulation of alternative metabolic pathways.

Therefore, the correct option for this question is A.

c) Carrier females have the genotype XFXf.

d) There are four possible genotypes, XFXf, XfXf, XFY, XfY

Explanation:

The mutation for hemophilia is on the X chromosome. Females have two X chromosomes and males have one.

Let's say that the mutated allele is f and the normal allele is F.

A carrier female has the genotype XFXf. A hemophilic man has one X chromosome. and since he is affected, must have the mutated allele. He must have the genotype XfY.

The punnett square below shows the cross

                   XF                     Xf

Xf              XFXf                   XfXf

Y                XFY                   XfY

a) As we saw, carrier females have the genotype XFXf. In the cross, there 1:4 chance that phenotype will occur.

b) A normal male has the genotype XFY. In the cross, there 1:4 chance that phenotype will occur.

c) Carrier females have the genotype XFXf.

Answer:

[tex]V =2m/s[/tex]

Explanation:

Given:

Represent

- Susan's velocity with [tex]V_s[/tex]

- Michael's velocity with [tex]V_m[/tex]

[tex]V_m = 7m/s[/tex] eastwards

[tex]V_s = 5m/s[/tex] westwards

Required

Determine how fast is [tex]V_s[/tex] relative to [tex]V_m[/tex]

From the question, one train moves eastwards while the other moves westwards.

This means that travel in opposite travel and the relative speed (V) is calculated as:

[tex]V = V_m - V_s[/tex]

Substitute values for [tex]V_s[/tex] and [tex]V_m[/tex]

[tex]V =7m/s - 5m/s[/tex]

[tex]V =2m/s[/tex]

Hence, the Susan's train is moving 2m/s in relative to Michael's train

Answer:

Humans shiver when it is very cold.

Explanation:

"Homeostasis" is the ability of the body to regulate itself in order to maintain a steady state. This includes mechanisms that allow automatic adjustment when the need for it arises. Covering ourselves with a blanket, taking a shower and turning on the air-conditioner are "not self-regulated" activities because they are done "intentionally" by the person. It is only "shivering" that shows the body's regulation of heat.

When the environment is cold, the skeletal muscles of the body respond by rapidly contracting and relaxing. This is what you call as "shivering." It produces heat through "respiration." Thus, it helps increase the body temperature.

Answer:

Hypothesis is a educated guess

Explanation:

Answer:

shedding

Explanation:

they would lose hair/fur allowing more waste heat to be lost into the environment so that the body could be cooler.

If the environmental temperature increases, the animal is most likely to shed, which is present in the third option because shedding the fur that is present on the skin is helpful for the relief of the heat.

Heat regulates the internal temperature, organ activity, blood pH, and a variety of other functions in the animal body. Animals living in colder climates have more hair and fat than those living in warmer climates, which is due to their need to protect their internal body temperatures. In the case of colder weather, the skin or the fur acts as an insulator and protects the animal by conserving the heat, while in a hot climate, the animals shed these in order to release the heat.

Hence, as the environmental temperature increases, the animal is most likely to shed, which is present in the third option.

Answer:

Gravity is the force that gives weight to objects and causes them to fall to the ground when dropped. Two major factors, mass and distance, affect the strength of gravitational force on an object. You witness the first factor in everyday life - more massive objects are heavier.

Explanation:

"Acceleration due to gravity" typically refers to the increase in speed of a falling object due to the gravitational pull of the Earth. If jump out of a plane, your speed increases towards the Earth (or the center of the Earth really) due to the acceleration of gravity. If you throw a ball up in the air, it slows down and falls due to the acceleration of gravity. I guess it's specified because the force of gravity is causing the acceleration in these instances; as opposed to some other outside force.

RNA move information from the nucleus to the ribosomes for protein synthesis.

RNA is a compound that has a high molecular weight, and single stranded, they form the back bone of sugar.

RNA are known as messangers this is because they serve as intermediary between DNA(deoxyribonucleic acid) and ribosome as they move genetic information from DNA to ribosome where translation takes place.

Therefore, RNA move information from the nucleus to the ribosomes for protein synthesis.
