Which of the following is NOT a valid scientific method used by modern scientists to date fossils?A Use of index fossils
B Relative position of fossils in rock strata
C Analysis of nitrogen-14 isotopes
D Analysis of Uranium-238 isotopes

Answers

Answer 1
Answer: A Use of index fossils

Fossil records are described as the position of found fossils all through the surface or the layers of the earth. The older the fossils are, the deeper it is found. Fossil records are also considered to be gathered information about the total number of the discovered fossils and the data obtained from them. Fossil records are important guides to determine how life existed before. If you are to assemble a fossil, you will be able to see and tell the evolutionary changes that happened over the past years. Fossil records are evidences pointing out that life before is totally different from now.

Usually, it is observed that climates in coastal regions are moderate as compared to climates in the interiors of continents. Why is this so?

Answers

The water bodies affects the climate of the particular place because it influences the air pressure near the water bodies.

The heated air takes much energy to heat the water bodies so the environment there is moderate.

In case when the air is cooler than water then heat goes from water to air and it does not takes much energy to raise the temperature of the air.

In this way the climate is moderate at the coastal regions.

what energy conversion took place on a strawberry bush to make the suns energy turn into carbohydrates

Answers

The strawberry bush has green leaves in which photosynthesis can occur. During photosynthesis, sunlight energy is converted into chemical energy stored in carbohydrates. Photosynthesis occurs in the leaves of green plants. During photosynthesis, carbon dioxide and water are converted into glucose and oxygen using the energy of sunlight. The excess of glucose synthesized in photosynthesis is converted and stored as a starch. Thus, one energy (sun energy) is converted into another (chemical energy) in the process of photosynthesis.
