Answer:
In the population of the study, mutation in the achondroplasia gene is unusually high
Explanation:
In this population, the incidence of genetic mutation that leads to achondroplasia would be 6 children for every 30,000 births. In the general population, achodroplasia has an incidence of 1 per 30,000 births, which indicates that in this specific population, the mutation rate is high above average, which can be explained by a high prevalence of the gene in the population.
Achondroplasia is a genetic disease with inheritance of an autosomal dominant pattern and to suffer from the disease, only one copy of the defective gene is necessary.However, in recent years after several studies it has been possible to demonstrate that even achondroplasia could be generated even in new mutations in the germ cells of the parents.

Archaea?
Explanation:
Domain archaea holds micro-organisms that is bacteria that has cell wall consist up of peptidoglycan .The eukarya differ from the archea and bacteria in that cells are eukaryotic,meaning they consist up of a membrane enclosed nucleus and other membrane enclosed organelle
Answer:
Glycolysis
Explanation:
Glycolysis is the first step of cellular respiration, where glucose is turned into 2 pyruvate molecules.
This step happens in all living organisms, since it does not require oxygen and also occurs in the cytoplasm, which all cells have.
So, glycolysis is the process that all organisms do during cellular respiration.
Answer: the low-pressure areas on the map are the purple triangle and half circles
Explanation:
It consists of different layers of different thicknesses.
It allows visible light to pass through completely.
It contains gases that filter out ultraviolet radiation.
2. Matthew has recently learned that Earth’s atmosphere is made up of nitrogen, oxygen, water vapor, and many other trace elements. Which of the following is NOT a way in which gases in the atmosphere are helpful to life on Earth?
Carbon dioxide insulates Earth
Protection against radiation from the Sun
Barrier against violent storms and lightning
Oxygen stays within the atmosphere
3. Which of the following is a way the atmosphere helps maintain life on Earth?
The atmosphere helps maintain a moderate temperature.
The atmosphere draws water vapor from outer space.
The atmosphere has air currents that rotate the planet.
The atmosphere contains some gases that are toxic.
keep her skin protected. She wonders what else the atmosphere does that she takes for granted each day. The atmosphere allows which of the following to happen?
Meteorites to hit Earth’s surface
Chloroplasts producing oxygen
Reflection from the ocean's surface
Precipitation and the water cycle
5. Gases in the atmosphere are helpful to life on Earth because they offer protection from which of the following?
Poisonous gases from stars
Harmful radiation from the Sun
Collisions with other planets
Violent storms and lightning
6. Without the atmosphere, life on Earth would not be possible. Which of the following is NOT an explanation for how Earth’s atmosphere protects life on the planet?
It allows visible light to pass through completely.
It contains gases that filter out ultraviolet radiation.
It keeps Earth warm by trapping in heat.
It protects life from ultraviolet rays of light.
7. Alexander applies sunscreen to help provide protection from ultraviolet radiation. With what does the atmosphere provide protection for Earth?
Thick layers of ice clouds
Ozone in the upper atmosphere
Water vapor in the lower atmosphere
The reflective surface of the ocean
8. The atmosphere is often referred to as a blanket that covers Earth, keeping out harmful things and protecting life inside. Which of the following best represents a way in which the atmosphere helps maintain life on Earth?
The atmosphere provides air for oxygen.
The atmosphere controls the distance from the Sun.
The atmosphere helps rotate the planet.
The atmosphere provides protection from disease.
9. Which two gases in the atmosphere are essential to life on Earth?
Nitrogen and helium
Carbon dioxide and oxygen
Neon and argon
Helium and hydrogen
10. The atmosphere is made up of four different layers: the thermosphere, mesosphere, stratosphere, and troposphere. Which of the following is NOT true regarding the composition and structure of the the atmosphere?
The structure maintains safety against harmful UV rays.
The composition allows necessary gases for life on Earth.
The atmosphere allows Earth to rotate around the Sun.
The atmosphere is made up of nitrogen, oxygen, and a variety of gases.
Earth's atmosphere contains gases that filter out ultraviolet radiation. So, the correct options for 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 are D, A, A, D, B, A, B, A, B and C respectively.
The layer of gases that covers the Earth is known as the atmosphere. It is made up of roughly 78% nitrogen, 21% oxygen, and 1% additional gases like argon, carbon dioxide, neon, and methane. It is held in place by the gravity of the Earth. The troposphere, stratosphere, mesosphere, and thermosphere are the four principal layers of the atmosphere.
Gases in the atmosphere of Earth serve as UV radiation filters. CO2 acts as an insulator. The existence of life on Earth is not a result of atmospheric gases. A temperate temperature is kept by the atmosphere. The water cycle and precipitation are made possible by the atmosphere. Life on Earth benefits from gases in the atmosphere because they provide protection from harmful solar radiation.
Earth is protected by ozone in the upper atmosphere. The best way to think about how the atmosphere supports life on Earth is as the source of oxygen in the air. The atmosphere's carbon dioxide and oxygen are necessary for life on Earth.
So, the correct options for 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 are D, A, A, D, B, A, B, A, B and C respectively.
