Heat energy is transferred on Earth by the processes of convection, conduction, and radiation. How does heat energy cause materials to move during convection? Complete the sentences below.
It causes denser materials to ______.
It causes less dense materials to ______.
Answer choices are Rise, Sink, Reflect, Absorb.
Answer:
Heat can travel from one place to another in three ways: Conduction, Convection and Radiation. Both conduction and convection require matter to transfer heat. If there is a temperature difference between two systems heat will always find a way to transfer from the higher to lower system.
In heat transfer by convection, heat energy causes denser materials to sink and causes less dense materials to rise.
What is heat transfer?Heat transfer refers to the process by which heat energy is transferred from one point at higher temperature to another at lower temperature.
Heat energy is transferred on Earth by the processes of convection, conduction, and radiation.
Thus, during convection, heat energy causes denser materials to sink and causes less dense materials to rise.

How can a shortage of nutrients harm organisms in an ecosystem? How can an excess of nutrients harm organisms in an ecosystem? Give an example of each scenario to support your answers.
Answer:
Explanation:
Shortage of nutrients in an ecosstem can harm an organism because when nutrients are scarse or very limited for organism and did not meet up with the organism requirements, there will be reduced metabolism and this can cause malfunction. Shortage of nutrients can lead to decline in growth and can lead to spring up of some diseases in the organism because enough nutrients us not available for good metabolic processes and fight diseases.
For example when an organism is deficient in vitamins and carbohydrates, the organism will not have energy to power metabolic processes and for it's activities and vitamins deficient will make the organism not to have the ability to fight against disease.
Too much of nutrients also affect organisms negatively. When there is much build up of nutrients, it can be harmful to the organisms and restrict metabolic processes.
For example too much of nutriwnts like too much of fat can block blood artieries and veins and thus can lead to inability of blood to flow .

what do chromosomes store?
Answer:
A chromosome is a single, long molecule of DNA. These highly organized structures store genetic information in living organisms. Small sections of the chromosome, called genes, code for the RNA and protein molecules required by an organism.
where do convection currents occur.
A. in areas with the same temperature.
B. in areas with the same altitude.
C. in areas with different air pressures
D. in areas with different cloud types.
Answer:
the answer is C-in areas with different air pressures
Explanation:
Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated.
Answer:C. in areas with different air pressures
Explanation:
In a strand of DNA, if the percentage of thymine is 30%, what would the percentage of cytosine in the same DNA strand be?
Answer: 20%
Explanation:
I haven't learned this exactly yet, but if there is 30% of thymine, then there has to be 30% of adenine because they match. That would leave 40% for other Guanine and Cytosine, and since they also match that means that it is exactly half, meaning that there is 20% Guanine and 20% Cytosine.
Do you think these fish are an example of natural selection among two populations of the same species? Explain your answer.
Answer:
It depends on the fish (I do not see any pictures) Any fish is an example of natural selection.
Explanation:
A good example would be that polar bears grew and evolved to have white fur to blend in the snow to sneak upon prey. However, their brown bear counterparts failed to do that. So due to better camouflage and hunting technique, the polar bears survived more up north.
Answer:
The two fish are of the same species because they can mate with each other. Also, the characteristics of the blind cave fish enable them to live in caves. Eyes need energy. So, developing bodies with no eyes allowed these fish to function more efficiently.

PLEASE HELP!!!? Are humans an invasive species? Why or why not. GIVE TWO PIECES OF EVIDENCE TO SUPPORT YOUR OPINION.
Answer:
I think yes, humans are an invasive species.
Explantation:
I think humans are an invasive species because they are everywhere, and very few places in the world do not have humans. Humans are in control of the planet because of their number. Humans are not going to be extinct ever. They are always going to be here on earth. If somebody finds new land, they make a base/camp and send other people to live there and to populate it. Like in North america, settlers came and sent men to live there. They hunted animals and set up homes. Then, more and more people came and soon all that is left is a over populated land with citys and cars and humans everywhere.
I hope this helps. :)
Why are cells are able to harvest about 34% of the available stored potential energy in a glucose molecule? What happens to the other 66%?
Answer:
Why are cells are able to harvest about 34% of the available stored potential energy in a glucose molecule is because of the process of cellular respiration. And what happens to the other 66% is that it's used to make water from hydrogen ions and oxygen that converted to heat and used directly for energy to store as fat

people can obtain groundwater by drilling a well A. above the water table B. into an aquifer C. into the unsaturated zone D. into the impermeable.
Answer:
B. into an aquifer
Explanation:
People can obtain groundwater by drilling a well into an aquifer.
An aquifer is a porous and permeable formation where groundwater can be found.
Aquifer is usually found below the water table. In this regard, the pore spaces of this layer of the earth allows for the storage of ground water. When the aquifer is punctured, groundwater can be abstracted.Answer:

1) What two problems does the transfer of information from DNA to protein need to overcome?
Clues:
a. DNA is made of nucleotides.
b. Protein is made of amino acids.
c. DNA is located exclusively in the nucleus.
d. Protein is synthesized exclusively in the cytoplasm.
Answer:
The two problems that the transfer of information from DNA to protein must overcome are:
How to bring the information from the nuclear DNA to the place of protein synthesis?How to convert this DNA information into amino acids and then into proteins?Explanation:
The genetic information is found in the DNA and depends on a specific sequence of nitrogenous bases. This information is transcribed into the messenger RNA, whose base sequence is organized into triplets and codons, each of which encodes an amino acid, as well as establishing the pattern for starting and stopping the synthesis of a protein.
How to bring the information from the nuclear DNA to the place of protein synthesis?The DNA must be transcribed into messenger RNA (mRNA), a process that occurs in the nucleus of the cell. mRNA leaves the nucleus and travels to the cytoplasm, where amino acid synthesis will take place.
How to convert this DNA information into amino acids and then into proteins?Once in the cytoplasm mRNA binds to ribosomes, structures in charge of translating the sequence of nitrogenous bases RNA to synthesize amino acids. The set of ribosomes and rough endoplasmic reticulum are in charge of the assembly of amino acids to produce peptides and proteins.

First drag pink labels to pink targets to identify the digestive organs. then drag blue labels to blue targets to identify the source of each digestive enzyme or fluid.
Answer:
According to the diagram, the digestive organs on the pink targets includes:
a.) Liver, c) esophagus, d) gall bladder, e)Stomach, I) Small intestine j) Pancreas
The source of each digestive enzyme or fluid on the blue targets includes: b) bile, f) pepsin, g) Intestinal enzymes, h) Pancreatic juice.
Explanation:
The digestive system is the collective name used to describe the alimentary canal, accessory organs and a variety of digestive processes that takes place at different level in the canal to prepare food eaten for absorption.
Accessory organs of digestion generate various secretions which are poured into the tract to aid in the digestion of the food taken. They include: salivary gland, pancreas (secrets pancreatic juice), liver ( secrets bile), gall bladder ( stores bile).
