What is the greenhouse effect?

Answers

Explanation:

The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth.

The Earth’s atmosphere consists of a combination of gases. Scientists believe that we are creating air pollution, which causes an increase in some gases, such as carbon dioxide. Such increases make it difficult for the atmosphere to stay in balance, and heat radiating from the Earth is being trapped. What term refers to the sun’s energy being trapped in our atmosphere?

A) cumulus clouds


B) greenhouse effect


C) transpiration


D) convection

And I need an explanation

Answers

Answer:im guessing its the greenhouse effect

Explanation:The Earth's atmosphere is composed of Nitrogen (78%), Oxygen (21%), and other gases (1%). ... Due to increases in gases, like carbon dioxide, that trap heat being radiated from the Earth, scientists believe that the atmosphere is having trouble staying in balance creating the greenhouse effect

O
B. Four siblings' cells are identical to their parents' cells.
O
C. Four bacteria daughter cells are similar to their parent cell.
OD. Four bacteria daughter cells are identical to their parent cell.

Answers

Answer:

A. Four siblings' cells are similar to their parents' cells.

Explanation:

Genetics of offspring are based on the paten but it will never be identical to them. The reason why is when the male and female cells combine to form a child they mix and most of the time one will dominate the other. You can have cases where you have both alleles though. Sometimes they also mix to form a new one. But usually you'll get one from each parent.

A. Four siblings’ cells are similar to their parents’ cells.

Answers

Answer:

A. Nucleotide bases in one strand can only be paired with specific bases in the other strand.

Explanation:

Had the same question on a test. Hope this helps :)

DNA is a genetic material found in every living organism. DNA is made up of purines, pyrimidines, a pentose sugar, and phosphate backbone. DNA is a genetic material that carries information from parent to daughter cells.

The correct answer is:

Option A. Nucleotide bases in one strand can only be paired with specific bases in the other strand.

Characteristics of the DNA include:

1. DNA is a double-stranded genetic material, which is made up of four nitrogenous bases, adenine, cytosine, thymine, and guanine.

2. These nucleotides bind to specific nucleotide sequences present on the template strand of the DNA.

3. DNA consists of coded sequences known as genes, which are inherited from the parent to the daughter cells.

4. DNA undergoes a unique semi-conservative mode of replication.

Thus, the correct answer is the ability of the DNA nucleotides to bind to the specific bases in the other strand.

10. Which arrow or arrows represent reactions that demonstrate a conservation of mass and energy? Explain your answer.

Answers

6. Is false because the factory uses mechanical energy and when carbon is released into the atmosphere it is the process of chemical energy.

7. Is true because Solar energy is created when it is used in the process of photosynthesis in a plant. Then chemical energy is used when the plants create glucose.

8. Arrows C + F represent a release of carbon dioxide. Arrow C shows carbon being released into the air from the factory. Arrow F shows respiration and carbon being released.

9. The cycle would be made by process C and E. The process E happen when the organism dies and become a fossil. The organism could be a cow that eats grass(plants) that takes carbon from the atmosphere by doing photosynthesis.
The process in C happens when the factory (nonliving) using fossil fuel and produce carbon. The factory takes the fossil, use it as fuel, and return the carbon to the atmosphere.

10. The process of photosynthesis and cellular respiration can represent the law of conservation of mass and energy. In photosynthesis, you need sunlight(arrow A), carbon dioxide(arrow B) and water. The process will produce glucose which can be used in cellular respiration.
In cellular respiration, the glucose will produce energy which was made from sunlight. It will also produce water and carbon dioxide that will be released back into the atmosphere (arrow F)

Think of another science topic you studied earlier. How might considering scale be useful when investigating that topic? How is that similar to and different from how the crosscutting concept of Scale is useful in this unit?

Answers

Scale can be extremely important to consider when applying the conclusions of an investigation to a larger group.

Scale is defined as a series of measurements in a given ratio, in order to compare two objects or groups. Some examples include:

Scale modelsScale populations

In the case of scale models, one example may be creating a 1:100 scale model of a building. What this means is that the model created will be one hundred times smaller than the original.

The idea of scale is very important to consider when performing experiments. For example, if we were to take a sample of 10 people and test for a specific bacteria, which gives us a result of 1 in 10 (or 10%) of the people that test positive for the bacteria, it would seem as though it is a very small number of people. However, if we take scale into consideration we can apply this 10% to the global population, which will result in hundreds of millions of people who will test positive for the bacteria.

Scale is important to consider when performing any experiment or drawing conclusions because it offers a method to calculate and make an educated assumption as to the impact of the results on a population that would otherwise be impossible to test.
