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.

Explanation:
During an experiment, if you purposely change the temperature to test a hypothesis, the temperature is called the a. manipulated variable. b. responding variable. c. hypothetical variable. d. dependent variable.
Answer:
Option a (manipulated variable) would be the appropriate choice.
Explanation:
To analyze the influence on something like a dependent variable, another modified variable seems to be an important variable responsive to modifications in quite an analysis. Plainly defined, the variable has been adjusted to determine its effect on the overall outcome of the study. There would be only one manipulated component in a correctly planned analysis.The other options offered are not relevant to the situation described. So, the solution above is the best one.

How does the burning of fossil fuel affect the carbon cycle?
A.The more fossil fuels are burned, the less carbon dioxide enters the atmosphere, less than can be absorbed by plants or the ocean.
B.The more fossil fuels that are burned, the more carbon dioxide enters the atmosphere, more than can theoretically be absorbed by plants or the ocean.
C.The less fossil fuels are burned, the more carbon dioxide enters the atmosphere, more than can be absorbed by plants or the ocean.
D. The more fossil fuels are burned, the more oxygen enters the atmosphere, more than can be absorbed by plants or the ocean.
Answer:
B.The more fossil fuels that are burned, the more carbon dioxide enters the atmosphere, more than can theoretically be absorbed by plants or the ocean.
Explanation:
The most reasonable answer.
The more fossil fuels that are burned, the more carbon dioxide enters the atmosphere, more than can theoretically be absorbed by plants or the ocean.
What are fossil fuels?Fossil fuels are made from decomposing plants and animals. Coal, oil, and natural gas are examples of fossil fuels.
When fossil fuels are burned they release a large number of carbon dioxide a greenhouse gas in the air. This leads to increases in the temperature of the globe. If the temperature of the earth increases it leads to the melting of icebergs.
Coal, oil, and petrol are some examples of fossil fuels. Oil releases a huge amount of carbon when burned, approximately one-third of the total carbon on earth.
Carbon dioxide is a greenhouse gas, this gas generally releases trapped heat in our atmosphere.
Therefore, The more fossil fuels that are burned, the more carbon dioxide enters the atmosphere, more than can theoretically be absorbed by plants or the ocean. Option B is correct.

The sequence that best explains the relationship between DNA and protein structure and function is: DNA base triplets → amino acid sequence → protein folding pattern → protein shape and function
DNA is the genetic material found in living cells. They encode genetic information that are read and used to produce useful products in an organism. A triplet nucleotide sequence called CODON is used to synthesize an amino acid sequence via the process of transcription and translation. The amino acid sequence determines the folding pattern of the protein. The folding pattern of a protein molecule is responsible for the shape and function of that protein molecule. Therefore, the sequence that best explains the relationship between DNA and protein structure and function is: DNA base triplets → amino acid sequence → protein folding pattern → protein shape and functionLearn more at: https://brainly.com/question/14136689?referrer=searchResults

In eukaryotes the electron transport chain is composed of a series of electron carriers located in the blank of mitochondrion
Answer:
Facts that is right
Explanation:
In eukaryotes, the electron transport chain is composed of a series of electron carriers located in the inner membrane of the mitochondrion
The electron transport chain is composed of four large, multiprotein complexes. These protein complexes are formed of a series of electron carriers.
These complexes are embedded in the inner mitochondrial membrane and two small diffusible electron carriers shuttling electrons between them.These transfer electrons from electron donors to electron acceptors via redox reactions and joins this electron transfer with the transfer of protons across a membrane.Thus, in eukaryotes, the electron transport chain is composed of a series of electron carriers located in the inner membrane of the mitochondrion

When you exhale, what happens in the lungs?
A. Air moves from high pressure (in the lungs) to low pressure (outside)
B. Space in the lungs increases
C. Lung pressure decreases
D. Air moves from low pressure (in the lungs) to high pressure (outside)
Answer:
Conversely, exhalation moves the diaphragm up into the chest cavity and reduces the space in it. This forces the air, which is dense with carbon dioxide at that point, out of the lungs and windpipe. It then exits the body either through the nose or mouth. Usually, this requires no physical effort from the body.

What can you do to play an active role in cancer prevention?
Answer: Although humans cannot prevent all cancers, a healthy diet and weight followed by adequate exercise, sleep, and stress reduction all play a part in cancer reduction.
Cancer occurs when cells multiply uncontrollably and are not "cleaned up" by the body. We are dependent on our bodies recognizing and destroying old cells and foreign substances like toxins. When our body's fail to do this, either through stress, poor diet or being sedentary, cancer could result.

What happens to the atoms of a solid when the temperature increases?
Answer:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.

amylase**
Which soil-based compounds do plants use to create amino acids from glucose?

What is a lipid that makes up cell membranes and is used to create hormones?
cholesterol**
Cholesterol makes up cell membranes and is used to create hormones.
Cholesterol is a necessary lipid for the body as it contributes to the formation of cell membranes and hormones. However, high amounts of cholesterol in the blood have harmful consequences for health.
Cholesterol has different functions in the body such as:
- Formation of structures: It is one of the main components of the plasma membranes of animal cells.
- Contributes to the formation of hormones: sex hormones (progesterone, estrogens, and testosterone), corticosteroid hormones (cortisol and aldosterone).
- Contributes to the metabolization of calcium to obtain vitamin D.
Additionally, the options hydrocarbon (natural chemical compound obtained from the earth to be used as fuel), starch (natural macromolecule that contributes to the human digestion process) and glucose (the most abundant chemical compound in nature that serves as a source of energy for organisms) are not correct options, because these substances do not have the function of forming cell membranes and creating hormones.

Answer:
O a researcher who is investigating selective breeding of livestock
Explanation:
The Human Genome Project (HGP) aims at determining the full nucleotide sequence of the human genome, which can be used for the identification, characterization and mapping of the human genes. The livestock genome sequence exhibits a high level of conservation with the genomes of many mammals including humans. In consequence, the information obtained by mapping genes from the HGP can be of help to map livestock genes. The livestock genome mapping projects have greatly been helped by the increasing availability of human and murine genome sequences, which has been used in comparative genomics for the identification of candidate genes involved in animal traits.
