Cystic fibrosis is caused by a recessive allele. The frequency of this allele is 0.1 in a population of 2,500.
What is the frequency of the dominant allele?
How many people in this population will have cystic fibrosis?
How many people in this population are cystic fibrosis carriers? (Heterozygous)
Answers
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.
What is the Hardy-Weinberg equation?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 %

how would the solar eclipse be different if the moon was moved AWAY from the earth?
Answers
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.

Answers
Answer:
X-Ray
Explanation: It is just what they use
The X-rays represent the types of electromagnetic waves that the doctor will use to check the dog.
What are X-rays?X-rays can be defined as a special type of electromagnetic radiation that can be used to create images inside the body.
The wavelengths of X rays range from 11 picometers (pc) to only 10 nanometers (nm).X-rays are used in medicine because these types of rays can pass through the human and animal bodies.In conclusion, the X-rays represent the types of electromagnetic waves that the doctor will use to check the dog.

Astronomers often need to collect data and observations from distant objects to which it is dangerous for astronauts to travel. Which instrument helps astronomers safely collect samples from distant objects to which they cannot travel?
Answers
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.
What instrument helps astronomers safely collect samples?
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.

Why would invertebrates fertilise their eggs internally?
Answers
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.
