Describe the movement of water molecules in this diagram and identify the state of the solution. Explain why the water molecules moved in this direction
Answers
Answer:
A. Water molecules moved from compartment 2 to compartment 1.
B. The water molecules moved in this direction because the concentration of solutes in compartment 1 is greater than that in compartment 2
Explanation:
The setup in the diagram demonstrates the process of osmosis. In the setup, two solutions of different concentrations as shown by the difference in the number of solutes present in each, is separated by a semipermeable membrane. After sometime, it will be observed that the level of the solution in compartment 1 rises while that in compartment 2 reduces. This is because of the movement of water molecules across the membrane from 1 to 2. This process is known as osmosis.
Osmosis is the movement of water molecules across a semipermeable membrane from a region of lower solute concentration or higher concentration of water molecules to a region of higher solute concentration or lower concentration of water molecules until an equilibrium concentration is attained.
This movement of water molecules is due to the difference in concentrations of the two solutions as well as a presence of a semipermeable membrane which allows only water molecules to move across it but not solute molecules.

Which would be an adaptation in a rainforest, but NOT in a desert? A: Skin that blends in with green plants B: Better eyes for hunting prey C: Ability to store water for a long time (Obviously not the answer) D: Very small leaves to trap water
Answers
Answer: A: Skin that blends in with green plants
Skin that blends in with green plants is an adaptation in a rainforest, nut not in a desert. Thus, the correct option is A.
What are rainforest adaptations?Some of the most common animal adaptations in the rainforest include camouflage. This adaptation is much like soldiers in the army wear camouflage to blend in with their outside environment, animals use camouflage to move around the rainforest undetected.
Rainforest plants show adaptations which help them to survive better including the shallow root systems which enable them to obtain more moisture and tap into the rich supply of nutrients which are available from rotting plants and animal materials in the upper soil layer of the forests. The leaves of the rainforest trees have special adaptations and are noticeably different from that of eucalyptus leaves.
Therefore, the correct option is A.

During ecological succession, why is one type of tree that is short get replaced by taller
tree types?
Answers
Answer:
change in environment
Explanation:
During ecological succession, short type of tree get replaced by taller tree because the environment is in favor of the taller trees. The suddenly and drastically change that occurs in an ecosystem is the main reason for ecological succession. In this ecological succession, the old species becomes vanished and replace by new species which has the ability to survive in that changed environment. The short type of tree get replaced by taller tree because the shorter trees did not get sunlight and nutrients from the soil so tall trees takes their place. The tall trees are more competitive that short trees.

The statement “force equals mass times acceleration (F=ma)” is Newton’s second law of motion. Why is this a law rather than a theory?
A-It states, rather than explains, the relationship between the variables.
B- .It cannot be proven, whereas a theory can be proven.
C-.It may be revised if new information shows that the relationship has changed.
D- It was classified as a law because it is related to other similar discoveries.
Answers
Answer: it’s A
Explanation:
Newton’s second law of motion is a law rather than a theory because: A. It states, rather than explains, the relationship between the variables.
Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.
Mathematically, it is given by the formula;
[tex]Force = mass[/tex] × [tex]acceleration[/tex]
This ultimately implies that, Newton's Second Law of Motion is a law because rather than explain, it states the relationship between the three (3) variables;
Force.Acceleration.Mass.In conclusion, a law can be proven whereas a theory may be revised in the event that a new information shows that there is a change in relationship between the variables.

Using the data you just reviewed, create a scientific argument of one to two paragraphs that support or oppose the current flu vaccine recommendations.
Answers
The flu vaccine is essential in our society and should be encouraged and financed whenever necessary. That's because, as we know, the flu is a disease of rapid proliferation and that imposes risks to the lives of some people. The vaccine has the ability to reduce the risk of a person being infected with the flu virus by 50%, this percentage is essential for people who are more sensitive to this virus such as the elderly, pregnant women and people with respiratory problems.
In addition, it is important that the manufacture and distribution of this vaccine is always financed, because the flu virus is a very changeable circle that is constantly changing and needs to be combated annually.
Answer:
Flu vaccinations are fundamental as they reduce the risk of flu illness by over 50%.
Explanation:
Flu vaccinations reduce the risk of flu illness by over 50%. This makes this process extremely important and fundamental for all human beings as they not only protect the person who gets the vaccine, but it also contributes to the prevention of spreading to other people, especially children and older adults who possess a greater risk of developing flu complications.
The antibodies that are produced by the vaccine prevent the flu virus from attaching to a healthy cell. However, if a person has not been vaccinated, the virus will attack the healthy cells because there is an absence of antibodies that prevent this process.

Which of Charles Darwin’s main points is depicted in the image? Organisms within a population compete with each other to survive. Over time, beneficial variations will be passed on to future generations. More offspring are produced than can be supported by an environment. All organisms within a population have an equal chance for survival.
Answers
Answer:
A). Organisms within a population compete with each other to survive.
Explanation:
Charles Darwin in his evolution theory proposed that the organisms of all species emerge and develop via the 'natural selection' of tiny, inherited discrepancies and these disparities enhance the individual's ability to contest and compete with each other in order to survive and reproduce to continue their existence. This led to the emergence of the phrase 'survival of the fittest' which suggests that in this competition of 'natural selection', only the fittest will survive. Thus, option A is the correct answer.
