How does radiometric dating help scientists pinpoint the age of a fossil? A. In radiometric dating, scientists mix the carbon in a fossil with carbon from similar fossils whose age they know. By comparing the carbon, they can tell the exact age of the fossil.
B. Radiometric dating allows scientists to find fossils in only the lowest and oldest layers of sediment.
C. In radiometric dating, scientists place samples of a fossil in certain liquids until the samples dissolve. The rate at which they dissolve indicates the age of the fossil.

Answer 1

Answer:

Answer:

C. In radiometric dating, scientists place samples of a fossil in certain liquids until the samples dissolve. The rate at which they dissolve indicates the age of the fossil.

Explanation:

The radiometric dating is the technique that is used to date the rocks carbon contents and traces out their impurities.

When the fossils were formed and is compared with the abundance of the naturally occurring radioactive isotopes and is made of the chemical elements and fossils are kept in this solution to find their relative and absolute ages.

Answer 2

Answer:

C. In radiometric dating, scientists place samples of a fossil in certain liquids until the samples dissolve. The rate at which they dissolve indicates the age of the fossil.

Explain how the sun produces energy which is transferred to the earth by radiation

Answers

Nuclear fusion happen on the sun by colliding particles that release energy as they become a new particle. The energy that it create (thermal and electromagnetic) are radiated to the earth.

Which of the following statements is NOT true? A. You are exposed to nuclear radiation everyday.
B. Most of the nuclear radiation you are exposed to occurs naturally in the environment.
C. Naturally occurring nuclear radiation is called background radiation.
D. All natural radiation is at a level low enough to be safe.

Answers

Answer:

Option D

Explanation:

There are three major sources of background natural resources a) Terrestrial Radiation

; b) Internal Radiation and c) Cosmic Radiation

Cosmic Radiation is the radiation received from sun and stars. These radiations are received in traces as they go through different filters such as earth’s atmosphere, its elevation and magnetic field.

Terrestrial Radiations are received from radioactive minerals like uranium, radium and thorium. Since these minerals exists in soil and rock, their exposure is not harmful to mankind

Internal Radiation exists within the body of humans as radioactive potassium-40 and carbon-14 is presents with in the body since birth

Hence, option D is correct

im pretty sure that it is d all natural radiation is at a level low enough to be safe

Which of these would most likely result in a change to the current classification of an organism?

Answers

Hello. This question is incomplete. The full question is:

"Which of these would most likely result in a change to the current classiﬁcation of an organism? A- Discovering organisms with similar physical traits in the fossil record B- Finding a related organism that was previously considered extinct C- Linking the organism to different ancestors through DNA sequencing D- Observing organisms that occupy the same ecological niche. "

Answer:

C- Linking the organism to different ancestors through DNA sequencing

Explanation:

To formulate the oldest classifications, ecological and physiological characteristics were used, as well as all others that are available for the taxa in question. However, in recent years, classifications based on the similarity between genomes have been attempted, with great advances in some areas, especially when those from other fields of Biology are added to this information. Because of this evolution in the classification technology, a change in the current classification of an organism could occur by linking the organism to different ancestors through DNA sequencing.

The classification of living beings is part of the systematic, science that studies the relationships between organisms, and which includes the collection, preservation and study of specimens, and the analysis of data from various areas of biological research.

Hi There! :)

Which of these would most likely result in a change to the current classification of an organism?

An analysis of the DNA sequence of an organism will most probably result in a change to a current classification of an organism.
>>>DNA analysis is one of the new reasons why organisms/species are being re-evaluated . Basic genetic analysis information can change our ideas of how closely two organisms/species are closely related thus, their classification can change.

Which systems in the body work together to maintain blood sugar levels? Select the best answer.A.digestive, circulatory B.circulatory, endocrine C.digestive, endocrine, nervous D.digestive, circulatory, endocrine, nervous

Answers

The correct answer is D. The digestive, circulatory, endocrine and nervous system all work together in maintain blood glucose levels. Digestive system is responsible for metabolic process for breaking down food in utilizable form. Circulatory systme helps is dispensing glucose into different parts of the blood. Endocrine is responsible for release of hormones for controlling blood glucose levels. Nervous system is responsible for release of chemical signals for hunger/satiation.

At the point when glucose becomes low, the level of insulin decreases and different cells in the pancreas discharge glucagon, which makes the liver transform put away glycogen once more into glucose and discharge it into the blood. This conveys glucose levels move down to typical. The digestive and endocrine work together to maintain blood sugar levels, the digestive will be the one to carry the glucose and endocrine will process it. The answer is C.
