When working with eye shadow, a color is generally a medium shade that is close to the client skin tone

Answers

Answer:

When working with eye shadow, a base color is generally a medium shade that is close to the client skin tone

Explanation:

A color base is used to generate uniformity and smoothness on a surface that will be painted. This technique is used both in artistic paintings and in make-up, as the question above shows, showing that a color base is used on the eyes before the eye shadow is applied. This is because the color base, by standardizing the color of the eyelid, allows the colors of the eye shadow to stand out and appear more pigmented, in addition to allowing the eye shadow to last longer in the customer's eyes.

What kind of information can scientist get from soft body parts that they cannot get from hard body parts?

Answers

Answer:

Function and working mechanism.

Explanation:

Information such as function and working mechanism etc can a scientist get from soft body parts that they cannot get from hard body parts because these soft body parts perform their work continuously and we can study it through a number of ways and methods. The working mechanisms of hard body parts can't be study because they are not visible to any instrument and occurs inside their structure so that's why function and working mechanism are the information given by the soft body parts.

Describe how the life cycles of the grunion and the horseshoe crab are timed to the rhythm of the tides?

Answers

Answer:

Grunion (Leuresthes tenuis): life begins at high tide. During summer and spring, thousands of these fish swim up onto sandy beaches (carried in by high tide). This is called a grunion run, and it occurs ta night during the new moon and full moon when the tide is highest. The females wiggle into the sand and lay thousands of eggs as the males deposit sperm around them. Afterward, they are swept back into the sea. The spawning is timed so exactly that it occurs only on the second, third, and fourth days that follow a new or full moon. After the grunion eggs are fertilized, they incubate for two weeks until the next new or full moon occurs.

Horseshoe Crab (Limulus polyphemus): during late May and early June, vast numbers of horseshoe crabs come together in shallow bays, marshes, and inlets along the Atlantic and Gulf coasts, waiting to come up on the beaches to spawn. The signal to begin is provided by the moon. During the new and full moons, when tide is highest, the crabs come ashore. The female produces a cluster of tiny eggs on her abdomen, and the eggs are fertilized by the male's sperm, and then deposited out in the sand by the female. The next two weeks, the eggs incubate until they hatch during the next full or new moon. When the high water reaches the eggs, they hatch and go out into the ocean.

Test One: If I breed a short fur, FF female with a short fur, Ff male, then I will expect to see (all short fur; some short and some long fur; all long fur) offspring.

Since all these offspring only have one trait for long fur, this trait stays hidden in their DNA and is not expressed in their phenotype. All the offspring will have short fur.

Test Two: If I breed a short fur, Ff female with a short fur, Ff male, then I will expect to see (all short fur; some short and some long fur; all long fur) offspring.

Test Three: If I breed a long fur, ff female with a long fur, ff male, then I will expect to see (all short fur; some short and some long fur; all long fur) offspring.

Answers

Answer:

test two:

some short fur and some long fur will be seen.

this is because in some cases, the offsprings have only have the trait for short fur or just one trait for long fur and so short fur is expressed in the phenotype. in other cases, the offsprings have only the trait for long fur and so long fur is expressed phenotypically.

test three:

all long fur is seen.

since all the offsprings only have the trait for long fur and no trait for short fur, long fur is expressed in the phenotype.

Assuming a diallelic gene coding for the trait and expressing complete dominance, 1) all short fur. 2)some short and some long fur. 3) all long fur.

According to the information that was provided, we can assume that the trait fur length is coded by a single diallelic gene

dominant allele F codes for short fur

recessive allele f codes for long fur

We can also assume that the gene expresses complete dominance.

What is complete dominance?

It is the inheritance pattern in which the dominant allele completely masks the recessive allele.

This is the case of individuals that are heter0zyg0us for a particular gene and express the dominant phenotype. The dominant allele is hiding the expression of the recessive allele.

Many genes show complete dominance.

Cross 1:

Parentals) FF x Ff

F1) 100% short fur

All short fur

Cross 2:

Parentals) Ff x Ff

F1) 1/4 FF + 1/2 Ff / 1/4 ff

    75% short fur + 25% long fur

Some short fur, and some long fur

Cross 3:

Parentals) ff x ff

F1) 100% long fur

All long fur
