explain where. in the world. the hbs allele is mostly likely to be prevalent and why the allele persists in spite of the danger associated with having two hbs alleles

Answers

Answer 1

The hbs allele is most likely to be common in regions with high rates of malaria like African area. The heterozygotes are not negatively impacted and are provided a benefit in these areas, therefore the allele survives.

What does the Hbs allele correspond to?Sickle cell anemia, which develops when two copies of the Hbs allele are inherited, is a serious, chronic condition that can be fatal. Hemoglobin becomes aberrant as a result, forcing the red blood cell to assume a crescent-shaped form and becoming hard as opposed to flexible. The red blood cell's shape is slightly altered by inheriting one copy of the Hbs allele (becoming a carrier), but not significantly enough to impair function as in the full disorder.

why do you produce carbon dioxide when working out?

Answers

Answer: The lungs bring oxygen into the body, to provide energy, and remove carbon dioxide, the waste product created when you produce energy. The heart pumps the oxygen to the muscles that are doing the exercise. When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide.

The rocket will then be at least 19.5 m above the ground for the interval 0.75≤t≤3.25  

0.75≤t≤3.25

The time interval for which the rocket is more than 3200 km above the ground level is 61.25 seconds.

What is quadratic equation?

To solve this problem, we need to find the time interval for which the rocket's distance above the ground level is greater than 3200 km.

We can start by setting the equation for the rocket's distance above the ground level equal to 3200:

We can then solve this equation for t using the quadratic formula

[tex]480t - 16t^2 = 3200\\t = (-480 +/- sqrt(480^2 - 4*(-16)*3200)) / (-32)\\This simplifies to:\\t = (-480 +/- sqrt(480^2 + 256000)) /\\ (-32)t = (-480 +/- sqrt(2304000)) /\\ (-32)t = (-480 +/- 1500) / (-32)t = (-1980) /\\(-32)t = 61.25t = -24.25\pi[/tex]

Since the time interval we are looking for is positive, we can ignore the negative solution. The time interval for which the rocket is more than 3200 km above the ground level is therefore 61.25 seconds.

B. friction between the ball and the ground

C. force applied to the ground by the foot

D. force applied to the foot by the ball

Answers

Answer: D. force applied to the foot by the ball.

Explanation:

The basic premise of force is that for every action, there is a reaction. The reaction force is the force that pushes back so to speak, against the action that you initiated.

This reaction force by acting against us, ensures that we move forward by pushing us.

When the player struck the ball, the ball pushed back against the player and this force that was applied to the foot by the ball was the reaction force.

Colorblindness is an X-linked recessive disorder. If Abby has normal vision (but her father was colorblind) and Ryan is not colorblind. What are the chances that their daughter is colorblind? SHOW ALL WORK FOR CREDIT. (To insert a table in your answer if necessary click on the three dots, click on the icon that looks like a table and you can customize the number and type of boxes you need)​

Answers

Answer:

Let ‘Xᶜ’ be the recessive allele for colour blindness and ‘X’ be the normal (dominant) allele.

Since Abby's father was colour blind, Abby must be a carrier for the same.

Which means Abby's genotype would be ‘XXᶜ’.

Now, Ryan is not colourblind which means his genotype would be ‘XY’.

Now, talking about their daughter, she would inherit a normal ‘X’ from Ryan and either ‘X’ or ‘Xᶜ’ from Abby.

Which means she wouldn't be colourblind but she might be a carrier of the disorder.

XXᶜ × XY

⬇️ ⬇️

X, Xᶜ X

↘️ ↙️

XX , XXᶜ

Their daughter will have either XX genotype or XXᶜ genotype.

And her chances of being colourblind thus, becomes zero.

have a nice day

Answer:

The difference between mirror and lens lies in how light reflects when falls over their surface. When light interacts with any surface, mainly two things happen; Reflection and Refraction. The main difference between mirror and lens is that image forms by reflection, as the light falls on a mirror. In lens, the image is formed by refraction.
