Difference between unicellular and multicellular.

The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialised it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.

Multicellular and unicellular organisms are perform almost all the life running activities and processes such as respiration, reproduction digestion, breathing, and metabolism.

In unicellular organism division of labour is at the organ level on the other hand in multicellular the division of labour at cellular, tissue, organs and organ system level. Unicellular organism has simple body organization and multicellular organism have complex body organism.

Therefore,the best example that shows the levels of organization in a multicellular organism from the smallest level to the largest is cell, tissue, organ, organ system, organism. Thus, option B is correct.

can you explain in brief about gigatism and dwarfism​

Answers

Gigantism is a condition caused by excessive secretion of STH(somato trope hormone) before puberty. Individuals reach heights of about 2 meters.

Dwarfism(hypophyseal dwarfism) is caused by hyposecretion of STH before puberty. Individuals reach heights of about 1,20-1,30m

Is is all die to hormones.The pituitary gland produces growth hormone.Overproduction of growth hormone by frontal lobe of pituitary gland causes gigantism and it’s low production causes dwarfism

what is the primary difference between diffusion and osmosis

Answers

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

Answers

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.

Answers

Answer:

A.) A.DNA; D.Chromosome; E.Gene

Explanation:

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.

Therefore,  A.DNA; D. Chromosome; E. Gene
