Answer:

Explanation:

The independent and the dependent variables are the two principal factors needed in an experiment.

• Manipulated variable: Refers to all the variables in an experiment that provoke a response in another variable. They are also known as independent variables. The independent variable changes or is controlled and modified in the experiment to analyze how the other variable responds to it. The researcher can change it to see what changes it implies in an object, process, trait, or anything that depends on them, to study its effects on the dependent variable. Usually, the independent variable is represented by the X letter. In the exposed example, the researcher manipulates the water given to the plants.  One plant receives water that has been microwaved and the other plant receives regular tap water.

• Responding variable: Refers to the dependant variable. The dependent variable is the one that is being investigated, studied, and measured. It represents a quantity of something which value depends on how the independent variable is modified. A change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually identified by the letter Y.  In the exposed example, the dependent variable is the height of each plant after 2 weeks of treatment.

• Controlled variable: Refers to those variables in an experiment that are controlled and have no influence on the results. These variables do not affect the change in the dependent variable values. In the exposed example these are the light and pots.

Proteins

Explanation:

Biomolecules are any organic molecule, meaning they contain carbon and they are produced by cells in living organisms, and they generally aid in the functioning of that living cell. The four major types of biomolecules are carbohydrates, lipids, nucleic acids, and proteins.

Proteins are large biomolecules, as they are also macromolecules.

Proteins are responsible for cellular functions and regulation of the body's tissues and organs.

When we talk about providing structure for healing, then proteins fit perfectly as collagen works on quick healing while immunoglobulin is an example of a protein that fights of harmful organisms.

Ferritin, Hemoglobin is an example of a protein that transports essential molecules from one part of the body to a target organ or destination.

Insulin for example is a protein that sends signals to target organs and is considered very important.

Answer:

It's the picture of the dolphins tale or fin, whatever it's called.

In this case answer B.

Explanation:

The leaf isn't used for motion.

The tail is moved up and down etc.. and creates motion that helps the dolphin swim.

The apple isn't used for motion.

The wolf's eye is used for sight, not motion.

Thus the answer is picture B.

The structure that is most likely used for motion is the tail fin of the fish. The correct option is B.

Motion is changing or modifying an object when applying a force. The living body move or locomote with the locomotion organ. These are different types of locomotion organs in different organs.

There are different organs in different animals for locomotion and motion. In humans there are legs, in animals there are paws and in fishes, there are fins, in insects, there are wings and legs.

There is no movement made by the leaf. The dolphin swims with the assistance of its tail, which is moved up and down and in other directions. It is not used to move the apple. The wolf's eye is for sight alone, not for movement.

Thus, the correct option is B. the tail fin of the fish.

Reducing gene flow causes speciation because the species are not allowed to exchange genetic material.

When gene flow is blocked from exchanging between populations, this results in speciation that prevents the populations of the same species to exchange genetic material.

So we can conclude that reducing gene flow causes speciation because the species are not allowed to exchange genetic material.

See the answer below

Explanation:

It was important for Pasteur to place the broth in the flasks before heating rather than transferring it to new flasks after heating because the new flasks might be a source of contaminants in the form of microorganisms, hence, leading to a biased outcome.

In order to prevent cross-contamination and preserve the integrity of the outcome of the experiment, the broth needed to be placed in the flasks before heating instead of transferring it after heating.

Answer:

they do have skeleton which is called exoskeleton, main component is chitin

Fiddler crabs don't have a skeleton. Instead, they occupy a carapace, a rectangular shell. As they expand, the carapace is absorbed, and a new, larger one is produced.

The paraphyletic group of animals known as invertebrates lacks the notochord-derived vertebral column and does not even develop one. Except for the chordate subphylum, all animals fall within this classification.

To assist remove food from sand, they frequently dine in a watery puddle. Because both of a female's claws are little, she has an advantage over a male in terms of finding and consuming food. Feeding is more challenging for older males due of their main claw.

Therefore, fiddler crabs don't have a skeleton.

Answer:

Viruses are not made out of cells, they can't keep themselves in a stable state and they can't make their own energy therefore no.

Explanation:

Answer:

no Viruses are considered to be nonliving

Explanation:

Viruses resemble organisms because they can multiply. They are different because they are not alive: they are not cells, they do not use their own energy to grow or respond to their surroundings.

Answer and Explanation:

The criteria for maintaining a Hardy-Weinberg equilibrium are:  

If one of these points does not carry out, then the population under study is not in equilibrium.

Then the observed allelic and genotypic frequencies are different from the expected ones if the population under study was in H-W equilibrium.

Explanation: The more layers, the more water it absorbs.

Answer:

A virus attaches to a specific receptor site on the host cell membrane through attachment proteins in the capsid or via glycoproteins embedded in the viral envelope. The specificity of this interaction determines the host—and the cells within the host—that can be infected by a particular virus.

Answer:

Viruses initially stick to cell membranes through interactions unrelated to fusion proteins. The virus surfs along the fluid surface of the cell and eventually the viral fusion proteins bind to receptor molecules on the cell membrane (4). If only binding occurred, the two membranes would remain distinct.

Answer:

Precise, but not accurate

Explanation:

First, let's define precision and accuracy.

Precision: how close multiple measurements are

Accuracy: how close the measurements are to the true measurement

The three measurements are:

167.0 g, 166.9 g, 167.2 g

The true mass is 172 grams.

We can see that each measurement is far from the actual value of 172 grams: about 5 grams off. They are not close to the actual measurement, so they are not accurate.

The three measurements are very close to each other. They are all within 0.3 grams of each other. The measurements are all close to each other, therefore they are precise.

Therefore, the measurements are precise, but not accurate.

Answer:

More precise than accurate.

Explanation:

Precision is a measurement of how close your measurements to each other, accuracy is a measurement of how close your measurements are to the true value.

The correct option associated with the question is given as follows:

a.All macromolecules are monomers.

b.All macromolecules are polymers made up of smaller units.

c.All macromolecules are created by dehydration reactions.

d.All macromolecules contain carbon.

Answer:

The correct answer is: a. All macromolecules are monomers.

Explanation:

Macromolecules are huge biological molecules made out of thousands of covalently associated atoms. Carbohydrates, lipids, proteins, and nucleic acids are altogether macromolecules. Macromolecules are framed by numerous monomers connecting together, shaping a polymer.  

In doing such, monomers discharge water atoms as side products. This kind of reaction is called dehydration reaction, which signifies "to assemble while losing water."  

lipids are worked from an alternate arrangement of monomers that look like each other in creation and size. Lipids are not polymers, since they are not made up of monomers.
