Scientist can determine the age of ancient objects by a method called radiocarbon dating. The bombardment of the upper atmosphere by cosmic rays converts nitrogen to a radioactive isotope of carbon, 14C, with a half-life of about 5730 years. Vegetation absorbs carbon dioxide through the atmosphere and animal life assimilates 14C through food chains. When a plant or animal dies, it stops replacing its carbon and the amount of 14C begins to decrease through radioactive decay. Therefore, the level of radioactivity must also decay exponentially. A parchment fragment was discovered that had about 64% as much 14C radioactivity as does plant material on Earth today. Estimate the age of the parchment.

Over a period of several years, a large hospital kept track of the number of births of babies displaying the trait achondroplasia. Achondroplasia is a very rare autosomal dominant condition resulting in dwarfism with abnormal body proportions. After 120,000 births, it was noted that there had been 27 babies born with achondroplasia. One physician was interested in determining how many of these dwarf babies result from new mutations and whether the apparent mutation rate in his area was higher than normal. He looked up the families of the 27 dwarf births and discovered that 4 of the dwarf babies had a dwarf parent. What is the apparent mutation rate of the achondroplasia gene in this population? Is it unusually high or low?

Answers

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.

Which process do all organisms do when performing cellular respiration?

Answers

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.

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

Answers

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.

What is the atmosphere of the Earth?

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.

(Hint: look back at the assumptions made by the mark and recapture method).a. random loss of tags might sufficiently large to change the proportion of tagged fish.b. as tagged fish die and larvae that were not tagged reach maturity the proportion of tagged changes.c. The fish might eat the tags.d. we cannot assume tags would stay on longer than six months, so we need new tags for the fishfish.
