6 0

Answer:

Prokaryotic cells are simple cells whereas Eukaryotic cells are large and complex cells.

Explanation:

  • There is difference between the prokaryotic cells and eukaryotic cells in its structure and functions.
  • Prokaryotic cells lack well defined nucleus but contain DNA molecules called as nucleoid. whereas, Eukaryotic cell contains a well defined nucleus.
  • Prokaryotic cell is a single-cell and contains only one chromosome whereas eukaryotic cell is a multicellular which contains many chromosomes.
  • Features like growth, response and reproduction is present in both type of cell.

Mendel used single gene (or monohybrid) experiments to describe his law of segregation. He used _______ characters (or dihybrid)
allochka39001 [22]

Answer:

Law of Independent assortment

Explanation:

Gregor Mendel, who was regarded the father of Genetics, discovered principles that governs inheritance in his experiments. He discovered that the alleles of a gene will separate into gametes when he performed a crossed involving a single gene or character like height, pea color etc. He proposed his law of segregation based on this.

However, he considered two characters or genes in his cross, which he called a DIHYBRID cross. He discovered that the alleles of each different gene separates into gametes independently of one another i.e. without one gene influencing the other in each gamete. He called this principle his LAW OF INDEPENDENT ASSORTMENT.

He obtained a 9:3:3:1 phenotypic ratio for the F2 dihybrid offsprings which is only possible if each gamete equally likely contains two alleles of the two different genes in different combinations.

Which of the letters above best models a molecule of water moving into the membrane via an aquaporin?​
nika2105 [10]

Answer:

Letter B.

Explanation:

Aquaporins, also known as "water channels," are the main transport of water through the membranes of plant, animal, and bacterial cells. These channels allow the water to travel into and within cells and, at the same time, exclude the passage of ions and solutes.

What makes letter B the correct answer, is the form of transport and shape of the channel that allow water according to the osmotic gradient. In this model, letter A shows simple diffusion, while C and D seem to illustrate gated channels.
