what is the primary difference between diffusion and osmosis
Long answer here!
In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.
The movement of particles (such molecules or ions) from a region of higher concentration to a region of lower concentration is known as diffusion.
Thus, It happens in a variety of media, including gases, liquids, and solids. The inherent propensity of particles to travel down their concentration gradient in search of equilibrium is the driving force underlying diffusion.
On the other hand, osmosis is a particular kind of diffusion that entails the passage of water molecules over a membrane that is only permeable in certain places. It happens when the solute concentrations on opposite side of the membrane differ.
Thus, The movement of particles (such molecules or ions) from a region of higher concentration to a region of lower concentration is known as diffusion.

What geologic process creates an alcove
A) glaciation
B) wind erosion
C) tectonic uplift
D) coastal erosion
Answer:
wind erosion
- i know this question is older but i hope this helps anyone who may need it. :-)
The geologic process that creates an alcove is wind erosion, which is present in Option B, as the alcove is a recessed area in a rock or cliff face that is often semicircular in shape.
What is wind erosion?Alcove is created by the process of wind erosion. Over time, wind can carry abrasive particles, such as sand or small rocks, that erode the softer rock on the face of a cliff, carving out a hollow space. As the wind continues to erode the rock, the hollow can deepen and expand, forming an alcove. Alcoves are often found in areas with strong, consistent winds, such as desert regions, and can range in size from small niches to large, room-sized spaces. In addition to wind erosion, alcoves can also be created by other geologic processes such as water erosion or tectonic activity.
Hence, the geologic process that creates an alcove is wind erosion, which is present in Option B.

Which statement is true?(1 point) The Calvin cycle is the light-independent stage of photosynthesis and occurs in the thylakoid membrane. The Calvin cycle is the light-dependent stage of photosynthesis and occurs in the stroma. The Calvin cycle is the light-dependent stage of photosynthesis and occurs in the thylakoid membrane. The Calvin cycle is the light-independent stage of photosynthesis and occurs in the stroma.
The true statement about calvin cycle is "The Calvin cycle is the light-independent stage of photosynthesis and it occurs in the stroma"
Photosynthesis is generally the process whereby cells of autotrophic organisms obtain their food in form of sugars in the presence of sunlight. The photosynthetic process occurs in two stages namely: light dependent and light independent stage. The light dependent stage is the first stage, which occurs in the thylakoid membrane of the chloroplast. In this stage, ATP and NADPH is produced for the second stage.LIGHT INDEPENDENT STAGE is also known as CALVIN CYCLE. It is so called because it does not need light to occur. This stage occurs in the STROMA, where the glucose is synthesized.Therefore, the true statement about calvin cycle is "The Calvin cycle is the light-independent stage of photosynthesis and it occurs in the stroma"Learn more at: https://brainly.com/question/17600594?referrer=searchResults

The human genome is made up of 23 pairs of chromosomes that are found in the cell's nucleus and one tiny chromosome that is found in the mitochondria. Everything a person needs to grow and operate is encoded in their genome.
What is the genome organization in cell?The single linear bits of DNA that make up genomic DNA are connected to a protein called a nucleoprotein complex.
Chromosomes are made of a DNA-protein complex, and the 23 chromosomes found in the cellular nucleus are where almost all the genomic DNA is dispersed.
A genomic organization is the division of DNA molecules into chromosomes and their linear arrangement.
In addition to the three-dimensional structure of chromosomes, “genome organization” can also refer to the arrangement of DNA sequences inside the nucleus.

What type of organisms are most likely to be found as fossils?
Organisms with hard body parts such as a mineralized shell are much more likely to become fossilized as har parts are not fed by scavengers.
Types of organisms that are most likely to be found in the fossils have completely made up of hard bodies or at least some hard body parts.
The deposit of sediments and the finer the sediment deposited the likelier fossilization is to occurThe hard parts of organisms, for instance, bones, and teeth have had becoming fossils.Scavengers normally leave such hard parts, however, they also decay with time but this gives more time to be buried in sediments.These hards parts have better chances than the organisms with soft body parts to be found in fossils.
