During passive transport, materials move by simple diffusion or by facilitated diffusion through the membrane, down their concentration gradient. Water passes through the membrane in a diffusion process called osmosis.

The passive forms of transport, diffusion and osmosis, move materials of small molecular weight across membranes. Substances diffuse from areas of high concentration to areas of lower concentration; this process continues until the substance is evenly distributed in a system.

Eating potatoes with the skin as opposed to without the skin can increase dietary fiber intake. A medium-size baked potato weigh
KATRIN_1 [288]

Answer:

  • <em><u>There are 1.6g more of fiber in the the potato with skin than the potato with flesh only</u></em>

<em><u /></em>

Explanation:

In the internet, you can find that a regular potato (medium-sized) with the skin contains about 4 grams of fiber; and half that is  in the skin , thus a potato without skin contains about 2 grams of fiber.

In other site, I found that the source used to deal with this question states 4.2 grams of fiber for <em>White, Flesh and Skin (173 grams)</em> and <em>2.6 grams for Potatoes, Baked, Flesh Only (173 grams)</em>.

Therefore, using the second reference, the differnce in the amount of fiber, in grams,  for the potato with skin and the potato with flesh only is:

  • 4.2g - 2.6g = 1.6g

The answer is that there are 1.6g more of fiber in the the potato with skin than the potato with flesh only.

Which of the following statements is true?
Paraphin [41]

Functionality of Genes and chromosomes is described below.

Explanation:

  • Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes.
  • Genes are contained in chromosomes, which are in the cell nucleus.
  • A chromosome contains hundreds to thousands of genes.Every normal human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes.
  • A trait is any gene-determined characteristic and is often determined by more than one gene.Some traits are caused by mutated genes that are inherited or that are the result of a new gene mutation.
  • The body produces thousands of different enzymes. Thus, the entire structure and function of the body is governed by the types and amounts of proteins the body synthesizes. Protein synthesis is controlled by genes, which are contained on chromosomes.
  • the genotype is a complete set of instructions on how that person’s body synthesizes proteins and thus how that body is supposed to be built and function.
  • The phenotype is the actual structure and function of a person’s body. The phenotype is how the genotype manifests in a person—not all the instructions in the genotype may be carried out (or expressed). Whether and how a gene is expressed is determined not only by the genotype but also by the environment (including illnesses and diet) and other factors, some of which are unknown.
  • A karyotype is a picture of the full set of chromosomes in a person’s cells.

Nuclear envelope forms at each pole spindle dissolves chromosomes uncoil. True or False
Doss [256]

Answer:

True.

Explanation:

There are four phases which occur during karyokinesis, these are -

  • Prophase
  • Metaphase
  • Anaphase
  • Telophase

Telophase is the last phase of karyokinesis. The main events that occur during telophase are-

  • Uncoiling of chromosome occurs
  • Chromatin is formed
  • Spindle breaks down
  • Nuclear membrane or nuclear envelope if reformed

Thus it is clear that the events that are mentioned in the question denote truly about the Telophase.
