If a container is divided into two compartments by membrane, both compartments are filled with a solution A an B having similar solute concentration, and a solution B is having higher volume. As the solutions are of same concentration there is no osmosis between two solutions separated by a semipermeable membrane, they are said to be isotonic.
In this situation, water can freely pass the membrane without affecting the solute concentration on either side. Thus over a time both solution A and B will have no change in solute concentration and the level of solution B will be equilibrated with solution A.

Sound waves travel better through solid than through a gas. Explain why this is true.
Answer:
solids are more tightly packed together (the molecules) than liquid or gas so it allows it to travel through vetter/faster
Answer:
Explanation: Solids are packed together tighter than liquids and gases, hence sound travels fastest in solids. The distances in liquids are shorter than in gases, but longer than in solids. Gases are the slowest because they are the least dense: the molecules in gases are very far apart, compared with solids and liquids

Classification of organisms is defined as dividing living beings into different kingdoms based on their genetics, traits, and other features.
Why did Classification Schemes of taxonomists change?Taxonomists arrange and divide the organisms based on the DNA, traits, and features of the living organisms. The advancements in technology led the taxonomists to have more information on genetic lineage and arrange them accordingly. Introduction and discoveries of new species, their genetic make-up, and traits also contribute to the change of classification system. Molecular biology, cellular level studies, and genetics of species have contributed to the classification of organisms.
Thus, the given statements about the classification of organisms are correct.

Answer:
The mushroom is composed of two parts, the above ground part, and the underground part. Each part has its unique function and purpose in the life cycle of a mushroom.
Spores
It is usually released into the air and falls on the ground to start the life cycle of the mushroom. Seeds that acts as the mushrooms reproductive system.
Stem
A soft branch is supporting the mushroom’s cap.
Gill
Located under the cap, it produces the spore of the mushroom.
Mycelium
This part of the mushroom serves as the breeding ground of smaller mushrooms to grow.
Hypha
The microscopic filament that draws water and the organic matter necessary for mushroom development.
Volva
The remnant of a membrane that completely covers the immature mushroom.
Ring
A covering located under the cap surrounding the stem.
Cap
The upper part of the mushroom that protects the gills. It usually resembles a headdress, hence its name.

Which explanation best identifies the relationship between mitosis and
reproduction? *
Mitosis is a form of sexual reproduction because the daughter cells form from one
single parent cell.
Mitosis is a form of sexual reproduction because the daughter cells are genetically
different from the parent cell.
Mitosis is a form of asexual reproduction because the daughter cells form a new
nuclear membrane after reproduction
Mitosis is a form of a sexual reproduction because the daughter cells are genetically
identical to the parent cell.

What are the biological implications of the structure of the plasma membrane (how do your results about the fluid mosaic and findings relate to life and death in the ‘real’ world? Where could the materials you worked with be found affecting the real world?)
Answer:
Structure of Plasma Membranes
The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.

Young hermit crabs pick up sea anemones which live on their shells. The stingy tentacles of the anemone keep fish from eating the hermit crab, and the sea anemone is able to eat leftover food from the hermit
crab. Which best describes the relationship between the sea anemone and the hermit crab?
A commensalism
B. O mutualism
c. parasitism
DO predation
Answer:
mutualism.
Explanation:
Mutualism can be defined as an symbiotic relationship or interaction between two or more living organisms of different species that typically involves each organism benefiting positively. Therefore, mutualism influences the survival and reproduction of living organisms in their habitats.
In this scenario, young hermit crabs pick up sea anemones which live on their shells. The stingy tentacles of the anemone keep fish from eating the hermit crab, and the sea anemone is able to eat leftover food from the hermit crab. Therefore, the relationship between the sea anemone and the hermit crab is best described as mutualism because both of them are benefiting from the interaction.
Simply stated, the sea anemone provides protection (security) from predators for the hermit crab while the hermit crab provides food for the sea anemone.
Scientists compare the structures of a chicken embryo and a human embryo at the same stage of development. They find that both vertebrates have
similar shapes and structures, including the presence of gill slits and tails. How is this comparison of the embryos used as supporting evidence of
evolution?
The similarities suggest that chickens and humans are the direct descendants of modern-day fish with tails and gill slits.
The similarities suggest that vertebrates pass through each of the adult stages of their evolutionary history as they develop.
o
The similarities suggest that vertebrates can undergo genetic changes during development that lead to the evolution of new species.

How do the distances between the terrestrial plants compare to the distances between the gas giants?
Answer:
They are different from rocky or terrestrial planets that are made of mostly rock. Unlike rocky planets, gas giants do not have a well-defined surface – there is no clear boundary between where the atmosphere ends and the surface starts! The gas giants have atmospheres that are mostly hydrogen and helium.
Explanation:
I hope this helps!
They vary from planets that are predominantly made of rock, such as rocky or terrestrial planets. Unlike solid planets, gas giants lack a clearly defined surface, there is no discernible line separating the atmosphere from the surface.
What are terrestrial planets?Telluric planets are another name for terrestrial planets. The Latin words terra and tellus, which both indicate Earth, are the source of the words terrestrial and telluric, respectively.
While the terrestrial planets were warmed by the sun's rays, the Jovian planets developed above the frost line.
Worlds that could float on water and worlds appropriate for manned missions were created under very distinct circumstances, but they have some striking similarities. Every world in our solar system is different.
Therefore, the atmospheres of the gas giants are primarily composed of hydrogen and helium.

Is the Great Green Wall an example of Secondary Succession?
Answer:
The Great Green Wall is taking root in Africa's Sahel region, at the southern edge of the Sahara desert. The Great Green Wall is a symbol of hope in the face of one of the biggest challenges of our time - desertification. This game changing African-led initiative aims to restore Africa's degraded landscapes and transform millions of lives in one of the world's poorest regions, the Sahel.
