Select the correct answer. Which statement about natural selection is true? A. Natural selection and evolution are two terms for
Masja [62]

Answer:

C. Natural selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce.

Explanation:

Natural selection is an evolutional process by which species of living organisms with stronger or more beneficial traits have higher chances of survival and reproduction. In other words, it is the process by which organisms adapt and survive.

Organisms in a population are all different in their own ways. And those with characteristics or traits better suited for the environment are more likely to survive than those without. The selection prefers more beneficial traits and not wholly on the superiority of the organism. So, the survival and reproduction chance of an organism depends on the presence of traits beneficial to the environment, which is how nature selects. And in this process, those selected will dominate the population while those rejected will be reduced or even die.

Thus, the correct answer is option C.

Suppose the femur bone of an animal has 1,000 atoms of carbon-14 when the animal dies. How many atoms of carbon 14 will be prese
shtirl [24]

Answer:

After 6000 years, approximately 500 atoms of carbon-14 will be left in the femur bone of an animal which had 1000 atoms of carbon-14 when the animal died.

Explanation:

The half-life of a radioactive isotope of an element is the time taken for half the atoms present in a given amount of the element to undergo decay or disintegration. For example, the half-life of carbon-14 isotope is 5730 years. This means that, if there are 100 atoms of carbon-14 present in a given sample of a material, in the next 5730 years, approximately, 50 atoms of carbon-14 will be left in the material.

Since the half-life of radioactive isotopes are constant, these radioactive isotopes are used in the determining the ages of ancient life-forms as well as rocks.

In the given example, after 6000 years, approximately 500 atoms of carbon-14 will be left in the femur bone of an animal which had 1000 atoms of carbon-14 when the animal died.

Which carbohydrates are found in our genetic material?
Kisachek [45]

The carbohydrates found in our genetic material are the two sugars deoxyribose and ribose.

Carbohydrates are defined as organic compounds which occur in food and living tissue and include starch, sugars and cellulose. They are composed of hydrogen, oxygen and carbon.

Deoxyribose is a sugar found in the structure of DNA, while the sugar ribose is found in the structure of RNA.

DNA is the molecule that carries the cell's genetic information while RNA is the molecule involved in synthesis of protein using the coded information received from DNA.

Both DNA and RNA are termed as the genetic molecules of life.
