Answer:
Changes in the environment affect the food sources available for birds. For example, if a flood was to occur, there would be an abundance of fish to birds to eat. So birds with bigger beaks will be able to eat fish, to live and reproduce offspring with bigger beaks. While birds with smaller beaks will not be able to catch fish to eat, therefore decreasing the population of birds with smaller beaks.

The Canada lynx is a rare wildcat in Minnesota. The lynx has large "snowshoe' like feet that enables it to walk on top of deep, soft,
snows. Snowshoe hares are also common in the area. According to the graph of the interactions between the lynx and the hare, what
best describes their ecological relationship?
A)
Mutualism
B)
Predator/prey
C)Parasite/Host
D)
Interspecific competition
Answer: B) Predator/prey
=========================================================
Explanation:
The lynx is the predator that hunts and eats the snowshoe hare, which is the prey.
The graph shows that when the hare population is large, so is the predator population because they rely on the hares as a source of food. However, the more predators there are, the less prey there will be. This causes the prey population to decrease. In turn, this decrease causes the predator population to decrease as well. If there's less food, then some of the lynx population will starve to death.
At some point, the hare population will rebound and go back up due to less predators eating them. They have a better chance to survive. As the hare population goes up, so does the lynx population. They're both strongly linked together, and we have this cyclic pattern the graph indicates. You could say this is "the cycle of life" or "cycle of nature" so to speak.
This is a very simplistic viewpoint because it does not account for other factors such as other predators and other prey, and it also doesn't take account of things like habitat loss for instance. Despite that, such predator-prey models are still useful to understand the connection between the two species.

Explain how the structure of DNA determines the structure of proteins which carry
out most of the work of cells.
Explanation:
A; Structure and Function. All cells contain genetic information in the form of DNA molecules. Genes are regeions in the DNA that contain the instructions that code for the formation of proteins, which carry out most of the work of cells.
The linear order of nucleotides in a gene sequence is used to encode a specific protein by the sequential processes of transcription and translation.
Deoxyribonucleic acid (DNA) is a double helix molecule that contains the information required to synthesize all proteins present in an organism.
During the mechanism of gene transcription, a specific fragment of DNA referred to as a 'gene' is used as template to encode a complementary messenger RNA (mRNA) sequence.
Subsequently, this mRNA travels to the ribosome where it is used as a template to encode a specific protein.
The linear order of triplets of nucleotides or 'codons' in the mRNA sequence specifies the linear order of amino acids in the nascent polypeptide chain (i.e., the protein).
In conclusion, the linear order of nucleotides in a gene sequence is used to encode a specific protein by the sequential processes of transcription and translation.

Which refers to the ends of a magnet where the forces are strongest?
attracting forces
opposing forces
magnetic fields
magnetic poles
Answer:
Magnetic poles would be your answer
Explanation:
The ends of a magnet where the forces are strongest are called magnetic poles. These are the points where attracting forces and opposing forces occur due to the interaction of magnetic fields. The correct option is D.
What are magnetic poles?When talking about magnets, the ends where the forces are the strongest are referred to as magnetic poles. The poles are the points on a magnet where the magnetic field lines appear to originate or terminate. A magnet has two poles, north and south, and the magnetic field flows from the north pole to the south pole.
Magnetic fields are generated by electric currents. Opposing forces and attracting forces, which relate to magnets, describe how two magnets interact with each other. Two like poles (north and north, or south and south) repel each other because they have the same charge.
Two unlike poles (north and south) attract each other because they have opposite charges. The strength of these forces is determined by the distance between the magnets, as well as their sizes and orientations.
Therefore, the correct option is D.

Paleontologists construct a model of a dinosaur from its fossil bones and teeth. The fossil bones and teeth can help the paleontologists to infer all of the following about the dinosaur except the?
height of the dinosaur,
type of food the dinosaur ate
length of the dinosaur,
skin color of the dinosaur
Answer:
B - Dinosaur Skin
Explanation:
Unless the skin is mummified, like that of a Pinacosaurus, the chromatin in the bones will be completely deteriorated.
From fossils, scientists can learn more about dinosaurs. Scientists can learn about dinosaur lengths and tooth shapes from fossils. Scientists speculate on the weights, movements, and diet of the dinosaurs.
What are fossils?Fossils are defined as the well-preserved remnants of plants and animals whose carcasses were buried beneath ancient seas, lakes, and rivers in sediments like sand and muck. Usually, sedimentary rocks include fossils, though rarely, low-grade, fine-grained metamorphic rocks will as well. It's possible that the fossils have been removed, leaving molds in the surrounding rock.
Take note of pattern, color, and shape. Matthew continues, "Seek for something distinctive on the ground, and as you examine it, look for patterns." Dinosaur bones typically have a lined organic pattern, which are the original bone tissue's preserved Haversian canals.
Thus, from fossils, scientists can learn more about dinosaurs. Scientists can learn about dinosaur lengths and tooth shapes from fossils. Scientists speculate on the weights, movements, and diet of the dinosaurs.

What happens to DNA once transcription is done?
O It is destroyed.
O It makes more copies of itself right away.
O It zips back up until it is necessary to transcribe the gene again.
O It mutates.
Answer:
it makes more copies of itself right away
Explanation:
transcription is the process by which the information in a strand of DNA is COPIED into a new molecule of the messager RNA
When DNA transcription is done, it zips back up until it is necessary to transcribe the gene again (option C)
What is DNA transcription?The process of DNA transcription involves copying the information, from DNA into RNA.
Once transcription is complete the DNA molecule returns, to its double helix structure. This occurs because DNA is highly stable and doesn't require transcription. The DNA molecule is transcribed again solely when the cell requires production of a protein.
With the above information, we can conclude that when DNA transcription is done, it zips back up until it is necessary to transcribe the gene again (option C)

What is meant by "concentration"? How can you increase the concentration of salt (electrolytes) in a solution of water? How can you decrease the concentration of electrolytes in a solution?
Answer:
See the answer below
Explanation:
The concentration of a solution refers to the amount of solute that is dissolved in a particular amount of solvent.
In order to increase the concentration of salt in a solution of water, more solute (that is, the salt) would be required to be added to a fixed volume of the solution. The more the amount of the salt added, the more the concentration of the solution provided the volume remains constant.
In order to decrease the concentration of electrolytes in a solution, more solvent would be required to be added to the electrolyte while keeping the dissolved solute constant. The more the added solvent, the lower the concentration as long as the amount of solute dissolved remains constant.

Photosynthesis removes carbon from the atmosphere, respiration adds carbon to the atmosphere.
What is photosynthesis?Photosynthesis is defined as the process through which plants convert carbon dioxide, water, and sunshine into oxygen and sugar for energy.
It can also be defined as a method used by plants and other living things to change light energy into chemical energy that can then be released through cellular respiration to power the organism's activities.
Through photosynthesis, plants transport carbon from the atmosphere into the biosphere and up the food chain. They use solar energy to chemically combine carbon dioxide, oxygen, and hydrogen from water to create sugar molecules.
Photosynthesis is primarily used to convert solar energy into chemical energy, which is then stored for use at a later time.
Thus, photosynthesis removes carbon from the atmosphere, respiration adds carbon to the atmosphere.

Protein are digested and transported by fellow proteins. Give vivid example to support the statement
Answer:
Proteins are digested in the body when ingested food from a protein source, is broken down in the stomach by enzymes like Chymotrypsin, trypsin which are both proteins, their common goal is to convert protein into a more simple form or simplest form ( Amino acids). This enzyme (Chymotrypsin and trypsin) are Proteins and they act as biological catalysts that are responsible for breaking proteins down.
An example of how Proteins are transported by fellow proteins is the case of Ferritin. Ferritin is an essential protein in the cell of the body that regulates the amount of iron available to the body. This is important for the hemoglobin in red blood cells.
