Suppose a scientist must choose whether to publish a report in a newspaper or in a peer-reviewed journal. What is a benefit of publishing in the journal?
Answer/Explanation:
Because the journal is peer-reviewed, it means their report is assessed and critiqued by experts in the field. This means the data is more reliable and more likely to be trusted by other scientists in the field.
Additionally, the journal is likely to be specialized and used to accepting scientific reports, meaning they will have certain regulations and criteria for publishing.

each of my nucleotides includes a phosphate sugar and base am i dna or rna
Nucleotides are defined as the building blocks of DNA and RNA. These are the genetic material found in every living cell. The nucleotides are made up of sugar, a phosphate group, and nitrogenous bases.
The molecules like DNA and RNA have some of the building blocks same. The pentose sugar and nitrogenous bases. The molecule when composed of sugar molecules and nitrogenous bases are termed as a nucleoside.
The addition of the phosphate group to a nucleoside forms the nucleotide.
RNA is composed of nitrogenous bases (adenine, cytosine, uracil, and guanaine), pentose sugar (ribose), and a phosphate group.
DNA is composed of nitrogenous bases (adenine, cytosine, thymine, and guanaine), pentose sugar (deoxyribose), and a phosphate group.
Thus, DNA and RNA are nucleosides consisting of nitrogenous bases (purines and pyrimidines) and sugar groups.
Therefore, the correct answer is the molecule can be DNA or RNA.

Which statement about the relationship between the ocean and the rest of Earth's water is true
A. The ocean is connected to all of Earth's freshwater through evaporation and precipitation.
B. The ocean is connected to all of Earth's freshwater through circulation.
C. Freshwater sources are connected to each other through evaporation and precipitation.
D. Ocean waters are connected to each other through circulation. Salt water and freshwater are not linked in any way
please help me asap
Answer:
Choice A
Explanation:
The water cycle connects all types of water, since the clouds of sea water or fresh water are moved then become rain somewhere else.
The statement about the relationship between the ocean and the rest of Earth's water is true, is the ocean is connected to all of Earth's freshwater through evaporation and precipitation. The correct option is A.
What is the ocean?About 71 percent of the surface of the Earth is covered by the ocean, a vast body of saltwater. The abundance of water on Earth is truly exceptional.
Water helps link the Earth's lands, oceans, and atmosphere into a cohesive system, which is essential to sustaining life.
The oceans not only contribute evaporated water to the water cycle, but they also permit water to travel throughout the world as ocean currents. Oceans serve as nature's reservoirs for water, which it uses to power the water cycle.
Therefore, the correct option is A. The ocean is connected to all of Earth's freshwater through evaporation and precipitation.

How does being small help cells survive?
Cells are small in size because it is very important that they have a surface area to volume ratio that would allow adequate intake of food nutrients, as well as the excretion of waste materials.
A cell can be defined as the fundamental (basic), functional, structural and smallest unit of life found in all living organisms.
According to cell type, living organism are mainly divided into two (2) main groups and these are;
Unicellular organisms: these are living organisms that are single-celled i.e they have a single cell.Multicellular organisms: this category of living organisms have many (multiple) cells.It is very important that the surface area to the volume ratio of cell is small, so as to allow enough materials such as food, move through the cell membrane quickly for the survival of the cell.
Hence, cells are small in size because it is very important that they have a surface area to volume ratio that would allow adequate intake of food nutrients, as well as the excretion of waste materials.
In conclusion, the smaller a cell, the larger would be its surface area to volume ratio.

Based on the video, do you think changes to the environment could still affect living things on Earth today? Explain your answer using information from the video to support your argument.
Answer:
I didn't see the video but global warming might be one.
Explanation:
Due to global warming the polar ice caps are melting, so that means a decrease in the food a polar bear might have.
Answer:
An ice age caused Earth’s oceans to cool, which killed many of the unicellular organisms. When the ice age ended and Earth warmed, the continents broke apart. This event allowed the shallow seas to cover the continents. The warming of Earth, accompanied by the seas covering the land, created the proper conditions for multicellular organisms to form.

Which of the following is NOT evidence of plate tectonics?
1. distribution of fossils
2. location of earthquakes
3. rain forest depletion
4. the shape of the continents
Rain forest depletion is not evidence of plate tectonics.
• Plate tectonics is responsible for the distribution of fossils on distinct continents, for the continental and ocean floor features comprising volcanoes, mountains, trenches, and faults, for the occurrence of earthquakes, and the shape of the continents.
• On different continents, the fossils are identical to the fossils found on the continents, which were once connected.
• The majority of the oceanic and continental floor features are the outcome of the earthquake and geological activity along the plate boundaries.
• The depletion of rainforest is not a result of plate tectonics. The major reason for rainforest depletion are agriculture and fuelwood collection.
• Apart from this, some of the human activities like logging, mining, development of large dams and industry is also major cause of rainforest depletion.
Thus, rainforest depletion is not evidence of plate tectonics.
