Answer:

The present value after 2 years is $98

Explanation:

Given

[tex]a = 200[/tex]

[tex]r = 30\%[/tex]

[tex]t = 2[/tex]

Required

Determine the new value

This is calculated using:

[tex]y = ab^t[/tex]

Where b =

[tex]b = 1 - r[/tex]

This gives:

[tex]b = 1-30\%[/tex]

[tex]b = 1-0.30[/tex]

[tex]b = 0.70[/tex]

So:

[tex]y = ab^t[/tex]

[tex]y =200 * 0.70 ^2[/tex]

[tex]y =98[/tex]

The present value after 2 years is $98

Answer:

$98

Answer: C.) Into the heart

Once the ventricles flow through veins, the blood goes to the heart, it literally goes to the heart so the heart can pump the blood to your veins and it flows throughout your body.

Answer:

They study nearby objects and match their properties with those of distant objects.

Explanation:

I have already took a test for this.

Since we are unable to reach stars or collect samples from distant galaxies, electromagnetic radiation, or light, is the only means for far-off things in space to communicate with us.

Telescopes or other devices that have been launched into space as space observatories gather information about distant planets, galaxies, and other astronomical objects.

Numerous telescopes sensitive to various regions of the electromagnetic spectrum are used by astronomers to explore objects in space.

Although the nature of all light is basically the same, how astronomers observe light varies on the region of the spectrum they are interested in.

Therefore, telescopes are light collectors, light is responsible for Hubble Space Telescope.

Answer: Only the California condor is endangered

Explanation:

Answer:

The Isopropanol had a lower heat of vaporization than that of water, meaning that it didn't have to have as much energy to accomplish a phase change, in this case evaporation.

According to the forces of attraction, isopropanol has lower heat of  vaporization as compared to water .

Forces of attraction  is a force by which atoms in a molecule  combine. it is basically an attractive force in nature.  It can act between an ion and an atom as well.It varies for different  states  of matter that is solids, liquids and gases.

The forces of attraction are maximum in solids as  the molecules present in solid are tightly held while it is minimum in gases as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.

The physical properties such as melting point, boiling point, density  are all dependent on forces of attraction which exists in the substances.

Answer:

For example, the allele frequency of the mutant cystic fibrosis allele among Caucasians is 0.025, while the frequency of the normal allele is 0.975.

Explanation: hope fully this helps

The frequency of the dominant allele is 0.975, and the frequency of the cystic fibrosis (recessive) allele in the population is 0.02 (or 2%). 42 % is the people in this population are cystic fibrosis carriers.

Hardy-Weinberg equation states that there will be no change in the genotype of a population unless, there is any evolutionary change happens.

This is the Hardy-Weinberg equation

p2 + 2pq + q2 = 1 and p + q = 1

The  people in this population are cystic fibrosis carriers

2pq = 2 (0.7 x 0.3) = 0.42 = 42%

Thus, the correct option is 0.975, 0.02 (or 2%), and 42 %

The doctor do the X ray of her meniscus.

Explanation:

The doctor do the X ray of her meniscus in order to find out the damage in the meniscus, if the damage occurs on the outside of meniscus so it can be heal itself but if the meniscus is deeply damaged so it can only be repair through surgery. If the meniscus is removed, the Sue will not be able to maintain her regular active schedule because there is no shock absorber in your knee which absorb large stress so she can't  do her regular activities.

Answer:

The Sun is completely blocked in a solar eclipse because the Moon passes between Earth and the Sun. Even though the Moon is much smaller than the Sun, because it is just the right distance away from Earth, the Moon can fully blocks the Sun’s light from Earth’s perspective. Sometimes the Moon is far enough away that it doesn't create a total solar eclipse. However, once the Moon's growing orbit takes it approximately 14,600 miles (23,500 km) farther away from Earth, it will always be too far away to completely cover the Sun. That won't happen for a long time though.

Answer:

I am writing this in response to a letter regarding evolution. Evolution is increasingly solid, not shaky. Darwin’s “theory” or explanation was a way of understanding what he had discovered (which did not include genes, chromosomes, DNA or nucleotide bases). Our explanations now include genetics and the commonality of mutation.  

Proofs are solid, not in question by serious scientists. Direct observation is one, which we see in the fact that this year’s flu evolved a little too far from last year’s, so flu shots are less effective this year than we would like them to be.  

Fossils tell the story well: whales with legs, dinosaurs with feathers and Tiktaalik. The latter was found in the Canadian north and is part fish, part amphibian, before there were ever any amphibians. Imperfection is a good proof: think of your useless appendix, the very bad design of your ankles, knees, and back (talk to a chiropractor about that).  You have big toes because they used to be useful thumbs for your grasping feet.

Many other animals and even plants similarly have flaws that show their evolutionary past. Two large human chromosomes reflect the coming together of two chimpanzee chromosomes each.

Answer:

The advantage of inside fertilization is that the fertilized egg is protected against dehydration on land. The embryo is segregated from the woman, limiting young predation. The fertilization of internal eggs by a certain male is also improved.

Explanation:

Interior fertilization is the union in the female body of the egg and the sperm. The female has more control over internal fertilization, as opposed to its counterpart, exterior fertilization. There has to be a technique for males to introduce the sperm into their reproductive system in order for internal fertilization to occur.

Copulation, an intromittent organ, is inserted into the vagina or cloaca in mammals, reptiles, and some other group of species. The cloacal kiss is employed in most birds, and the two animals squeeze their cloacas together as sperm is transferred. Salamanders and Spiders are internally regulated by passing a bundle of sperm from the male to the female. Some insects and certain mollusks are fecundated. The embryos are placed as eggs in the organisms or continue to develop within the mother's reproduction tract as young, viviparous creatures after fertilization.
