As you can see in the picture presented below, the DNA sequence in individuals with normal hemoglobin and in the individuals with sickle cell hemoglobin differ in only one nucleotide. However small, this difference in the nucleotide changes  the amino acid from glutamate to valine, changing the structure of the protein in the red blood cells.

The offspring {blank} reproduction are more likely to survive changes in the environment.
geniusboy [140]

Answer:

sexual

Explanation:

there are two types of reproduction,

the boring kind and the fun kind

Uh i mean asexual and sexual

in asexual the DNA is copied pretty much exactly the same so there is no room for improvement so if something suddenly changes the organism dies.

In sexual, The DNA of 2 different organisms are combined and this allows for greater variation in genetic evolution. so if something in the environment happens, the ones with a better genes will survive and reproduce more while the other ones die.

A communications satellite transmits a radio wave at a frequency of 9.4 x 10^9 Hz. What is the signal’s wavelength? Assume the w
sergejj [24]
To calculate this we will use the light equation:
c=λ*f

We have Frequency f=9.4* 10^{9}Hz.
We know that speed of light in vacuum is c =3.8* 10^{8} m/s.
Since a unit of speed of light is m/s, we can change the unit of frequency Hz to 1/s, since Hz means cycles per second (f=1/T).

So:
f=9.4* 10^{9}1/s
<span>c =3.8* 10^{8} m/s
</span>
<span>c=λ*f
</span>⇒ λ= \frac{c}{f}
⇒ λ= \frac{3.8* 10^{8}}{9.4* 10^{9}}
⇒ <span>λ</span>=0.04 m

What change is observed in leukocytes during an allergic disorder (type I hypersensitivity) often caused by asthma, hay fever, a
blagie [28]

Answer:

Increase in eosinophils.

Explanation:

The leukocytes are the white blood cell that plays an important role in the immune system. The white blood cell include eosinophil, basophil, neutrophil and monocytes.

The allergic reactions that are caused by hay fever or asthma is marked by the excess increase in the number of eosinophils in the body. The eosinophils are the first to reach at the site of parasitic infections and protect the body during the allergic reactions.

Thus, the answer is eosinophils.

Why are common names a problem for scientist?
Bess [88]

It can be confusing because it isn't specific enough. In astronomy, the big dipper is not a spoon. It is a bear. Scientists know it as Ursa Major rather than a dipper or bear.
