B. the body's internal environment
OCthe body's external skin and hair
0
D. the body's support for movement

Answers

Answer:

B. the body's internal environment

Explanation:

Homeostasis is defined as the process of maintaining the internal environment of the body.

All the systems work together to maintain homeostasis. The nervous and endocrine systems are two important system that helps in maintaining homeostasis.

The nervous and endocrine systems are linked with hypothalamus that controls the internal environment of the body by releasing and inhibiting hormones. These hormones keep pH,  temperature,  and other internal conditions stable that support homeostasis.

Hence, the correct answer is "B. the body's internal environment".

In South Carolina, there is an area of shoreline called Grand Strand. Its central part is not protected by barrier islands. Explain what you could infer about the impact that water movement has on this area.

A. Water movement has caused strong waves to build the shoreline up through the process of deposition.

B. Water movement has caused longshore currents to erode the sediment from one end of this shoreline.

C. Water movement has caused this land to erode because there is no protection from strong waves.

D. Water movement has caused a build-up of various inlets to form a combination of tides and currents.

Answers

The impact that the movement of the water has in this area, is that the movement of the water has caused the erosion of this land because there is no protection against strong waves.

What causes marine erosion?

Marine erosion, also called maritime erosion, is defined as “the process of wear, transport and sedimentation of rocks and coastal soils by erosive agents”. Fundamentally, it can be caused by the action of three factors:

WavesCurrents and Tides.

With this information, we can conclude that the impact that the movement of water has in this area is that the movement of water has caused erosion of this land because there is no protection against strong waves.

state two features of diffusion that do no apply to active transport​

Answers

diffusion moves ions from high concentration to low using no metabolic energy and active transport uses metabolic energy in the form of atp to move ions from high concentration to low concentration

What does active transport require that diffusion does not? Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.

What two features distinguish active transport from diffusion? An example of diffusion is oxygen moving from the airways to the lungs - there is very little oxygen in the lungs but lots in the air. Active transport is the movement of particles from an area of low concentration to an area of high concentration. This process requires energy (ATP)

What are the 2 key features of active transport? There are two types of active transport: primary active transport that uses adenosine triphosphate (ATP), and secondary active transport that uses an electrochemical gradient. An example of active transport in human physiology is the uptake of glucose in the intestines.
Both use ion channels to move ions across the cell membrane, in or out of the cell. Differences: Passive Transport (or Diffusion) moves ions from high concentration to low, using no metabolic energy. Active Transport moves ions from low concentration to high, using metabolic energy in the form of ATP.

In a separate study, 68 rock pocket mice were collected from four different, widely separated areas of dark lava rock. One collecting site was in Sonora, Mexico. The other three were in Chihuahua, Mexico. Dr. Nachman and colleagues observed no significant differences in the color of the rocks in the four locations sampled. However, the dark-colored mice from the three Chihuahua locations were slightly darker than the dark-colored mice from the Sonora population. The entire Mc1r gene was sequenced in all 68 of the mice collected. The mutations responsible for the dark fur color in the Sonora mice were absent from the three different populations of Chihuahua mice. No Mc1r mutations were associated with dark fur color in the Chihuahua populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changes have different genetic bases.

How does this study support the  concept that natural selection is not random?  

Answer:

The study supports the  concept that natural selection is not random because in different areas with the same or very similar environmental characteristics, the same phenotype was produced by different types of mutations.  

Explanation:

All of the sampled animals are inhabiting dark substrate. Probably animals needed to camouflage to survive. Natural selection must have driven them to produce dark color, similar to the substrate color. So animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. The environmental condition is favoring the same phenotype.

Eye color in a particular strain of fly is influenced by one gene with two alleles: a dominant allele that results in red eyes and a recessive allele that results in sepia eyes. A red-eyed female from a true-breeding population is mated with a sepia-eyed male. The Fl offspring are all red-eyed. The Fl flies are allowed to interbreed, producing the following in the F2 generation.
Females: 40 red eyes; 13 sepia eyes
Males: 39 red eyes; 11 sepia eyes
Which of the following best describes the likely mode of inheritance for the eye-color gene?
a. The eye-color gene is likely autosomal because males and females have similar phenotype ratios.
b. The eye-color gene is likely autosomal because more females have sepia eyes than males do.
c. The eye-color gene is likely sex-linked because the males and females have similar phenotype ratios.
d. The eye-color gene is likely sex-linked because the males and females display both phenotypes.

Answers

Answer:

The correct option is a. The eye-color gene is likely autosomal because males and females have similar phenotype ratios.

Explanation:

Available data:

Eye color is influenced by a diallelic gene R dominant allele results in red eyesr recessive allele results in sepia eyesCross: true-breeding red-eyed female with a sepia-eyed maleF1: 100% red-eyed.F2: Females: 40 red eyes; 13 sepia eyes

              Males: 39 red eyes; 11 sepia eyes

77% of the total progeny has red eyes and 23% has sepia eyes.

Among females, 75% is red-eyed, and 25% is sepia-eyed

Among males, 78% is red-eyed, and 22% is sepia-eyed.

The general phenotypic ratio is 3:1

If the eye-color gene was sex-linked, the phenotypic ratios would be different. There would be a higher proportion of red-eyed females than red-eyed males. Females would only express red eyes, while males would express red and sepia eyes. This is

Cross:         X⁺X⁻   x    X⁺Y        (Note: The symbol + represents the allele R

Phenotype: red-eyed both                    and the symbol  - the allele r)                  

Gametes) X⁺       X⁻     X⁺    Y

Punnett square)    X⁺         X⁻

                      X⁺   X⁺X⁺     X⁺X⁻

                       Y    X⁺Y       X⁻Y

F2) 3/4 of the whole progeny would be red-eyed

     1/4 of the whole progeny would be sepia-eyed

  BUT

     Females: 100% red-eyed

     Males: 50% red-eyed and 50% sepia-eyed

These proportions are not coincident with the exposed real proportions

So,

c. The eye-color gene is likely sex-linked because the males and females have similar phenotype ratios.

If this gene was sex-linked, Males and females would not have similar phenotype ratios. This is FALSE.

d. The eye-color gene is likely sex-linked because the males and females display both phenotypes.

If this gene was sex-linked, Males would display both phenotypes, but females would only be red-eyed. This is also FALSE.

According to this, we can assume that this is an autosomal gene. If this is true, then

Cross:   Rr XX    x    Rr XY

Gametes) RX, RX, rX, rX

                RX, RY, rX, rY

Punnett square:

              RX       RX       rX       rX

RX      RRXX    RRXX   RrXX   RrXX

rX       RrXX      RrXX    rrXX    rrXX

RY      RRXY     RRXY   RrXY   RrXY

rY       RrXY      RrXY    rrXY    rrXY

F2)  From the whole progeny

      12/16 = 3/4 = 75% would be red-eyed       4/16 = 1/4 = 25% would be sepia-eyed

       Phenotypic ratio 3:1

       Among females

       6/8 = 3/4 = 75% would be red-eyed, R-XX        2/8 = 1/4 = 25% would be sepia-eyed, rrXX

        Phenotypic ratio 3:1

      Among males

       6/8 = 3/4 = 75% would be red-eyed, R-XY        2/8 = 1/4 = 25% would be sepia-eyed, rrXY

       Phenotypic ratio 3:1

The phenotypic ratio in all cases are 3:1.

b. The eye-color gene is likely autosomal because more females have sepia eyes than males do.

Both males and females exhibit sepia eyes in equal proportions. This is FALSE

a. The eye-color gene is likely autosomal because males and females have similar phenotype ratios.

Males and females do have similar phenotype proportions of red eyes and sepia eyes. This is TRUE

How does cooling of magma affect crystal size?

A) Slow cooling creates small crystals

B) Fast cooling creates both large and small crystals.

C) Slow cooling creates large crystals

D) Fast cooling create large crystals

Answers

Answer:

When magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large.

Answer:

I learned about this, Uhm...

C is the right answer bc igneous rocks cool and form crystals.

Lava, since it comes out of a volcano, cools faster and has smaller crystals since they could not be developed enough.

Magma, still underground, cools slower than lava because of all the density and heat, which causes bigger crystals.
