Look at the diagram below. It shows two solutions separated by a partially permeable membrane. Which number arrow shows the direction in which water molecules will move?
Answer:
Arrow no. 4
Explanation:
Water flows from a region of higher concentration to a region of lower concentration, i.e, osmosis.
Dilute solution means it has relatively less solute and more solvent, meaning more amount of water.
And just the opposite for concentrated solution.
So since the dilute solution has more water and concentrated solution has less, and water moves from a region of higher concentration to a region of lower concentration, option 4 is the correct answer.
During the osmosis process solvent is moved from a lower solute concentration to a higher solute concentration, hence arrow 4 defines the movement of water molecules.
What is osmosis?Osmosis is the process through which solvents move from a region of lower solute concentration to one of higher solute concentration across a semi-permeable membrane.
Water in the cell acts as a solvent and moves from lower solute concentration to higher solute concentration through a partially permeable membrane.
Conversely, in diffusion, molecules migrate from an area of greater concentration to regions of lower concentration without the need for a semi-permeable barrier.
Therefore diffusion of water molecules in the osmosis process from low solute concentration to high solute concentration, hence arrow 4 defines the movement of water molecules.

Which terms best complete the chart about characteristics of human development between fertilization and birth? Stages of Human Gestation First trimester Second trimester Third trimester - Embryo develops - Organs begin to develop - (1) - Starts swallowing - Fat begins to develop - (2) - All organs are developed - Can hear and see - (3)
Answer:
Im doing the unit test and i believe the answer is C
Explanation:
It makes the most sense if you have studied.
The stages of human gestation and their time duration are given below:
First trimester: After conception to 12 weeks.Second trimester: Between 12 to 24 weeks. Third trimester: Between 24 to 40 weeks. What do you mean by Fertilization?Fertilization may be defined as a biological event that occurs by the fusion of male and female gametes successfully to produce a zygote.
The embryo develops after four to five weeks of conception which is the first trimester, organs initiate to develop by the end of the first trimester.
Swallowing is initiated at the beginning of the second trimester, and all organs are completely developed by the initiation of the third trimester. While all senses of hearing and seeing are developed by the middle of the third trimester.
Therefore, each trimester is characterized with its own functionality.

How did the insertion of a nucleotide in a DNA sequence result in a phenotypic change in an organism
Answer:
if the nucleotide insertion occurs within the coding region of a gene (frameshift mutation), then it will change the open reading frame (ORF) of the resulting protein and thus also will alter the phenotype of the individual
Explanation:
A mutation is any change in the DNA sequence of the genome of a cell/organism. A point mutation is a genetic mutation where a single nucleotide is inserted, deleted or changed from the original DNA sequence. The insertion of a single nucleotide in the coding region of a gene is called frameshift mutation since this nucleotide base shifts the way the DNA sequence is read. A frameshift mutation changes the meaning of the codons that follow the inserted nucleotide base and thereby protein function is generally lost, thereby also affecting the resulting phenotype associated with this protein.

Alcon blue butterflies spend the first part of their lives as caterpillars that live with Myrmica ants. When a caterpillar lives with the ants, it pretends to be a Queen ant by making noises that make it sound like the Queen ant. Queen ants receive more food and better protection than any other ants in the nest. When the caterpillar mimics a Queen ant, the ants feed and protect the caterpillar instead of other ants in the nest. Which word best describes the relationship between the caterpillar and ants
Answer:
The correct answer is - parasitic.
Explanation:
The Maculinea Alcon butterfly has a unique relationship with species of Myrmica ants. The butterfly's caterpillars picked up by passing Myrmica ants, and take to their nests where this caterpillar makes sounds like the queen ants, and to this sound, all ants protect and feed this caterpillar instead of other ants.
Normally there is a mutualistic relationship between ants and caterpillars but in the case of The Maculinea Alcon caterpillar and Myrmica ants, there is a parasitic relationship.
How could the aquifer around the Los Angeles are in California be susceptible to an impact by a Tragedy of the Commons?
Answer:
Due to over-pumping of water.
Explanation:
The aquifer around the Los Angeles are in California could be susceptible to an impact by a Tragedy of the Commons because the people used more water than the aquifer receives. The excess use of water from the aquifer through the well causes depletion of water which results in the shortage of water to fulfill the needs of existing population so it is wise to use water efficiently and used lower or equal water the aquifer receives in order to maintain level of aquifer.

Mad cow disease is caused by deformed proteins called prions. The disease is spread when meat from an infected cow is eaten. Prions can make normal proteins deform into more prions. After a few years, the brain of an infected person or cow looks like a sponge full of holes. Are prions considered organisms?
Answer:
No.
Explanation:
No, prions are not considered organisms because they are proteins that the infection to the surrounding cells and tissue. Prion is a type of protein that can change normal proteins in the brain into abnormal. Prion diseases can affect both humans and animals and spread to humans by eating infected meat products. So we can conclude that prions are not organisms, they are proteins.
Owls can be found all over the world, EXCEPT ________. *

What is the ultimate role of ecological succession in an environment
Answer:
The stable, end stage of ecological succession in which the plants and animals of a community use resources efficiently and balance is maintained by disturbances such as fire. The ultimate goal of ecological succession. After a natural disaster and continues until a climax community is reached.
Explanation:
The ultimate role of ecological succession in an environment is to reach the equilibrium in an ecosystem.
What is Ecological Succession?This event involve in the steady and gradual change in a species of a given area with respect to the changing environment is called as ecological succession.
The changes are inevitable process where all biotic components of the ecosystem keep up with the changes in our environment.
This process ultimately reach equilibrium in the ecosystem and the community that achieves this referred as a climax community, where some species increase in number and others decrease.
The communities that undergo changes sequentially in an area is called sere, so it is also called as seral stage or seral community.
Evolution has taken place simultaneously with that of ecological succession, so all the communities we observe are the result of ecological succession.
