The immediate source of the intracellular fluid surrounding all human body cells is:_____.
densk [106]

The immediate source of the intracellular fluid surrounding all human body cells is capillaries.

Interstitial fluid forms the immediate environment of all cells.

What are capillaries?

  • Capillaries are very tiny blood vessels — so small that a single red blood cell can barely fit through them.
  • They help to connect your arteries and veins in addition to facilitating the exchange of certain elements between your blood and tissues.
  • Capillaries are delicate blood vessels that exist throughout your body.
  • They transport blood, nutrients and oxygen to cells in your organs and body systems.
  • Capillaries are the smallest blood vessels in your vascular system.

What are the contributions of each of these scientists to the cell theory? And how did that information contradict what was beli
SpyIntel [72]

M. J. Schleiden:

In the year 1838, a German botanist presented the first cell theory (Although his theory was ultimately disproved, it did contribute to a change in scientific focus to cellular processes.)

<h3>What is cell?</h3>

All living creatures and body tissues are made up of the smallest unit that can live on its own. The cell membrane, nucleus, and cytoplasm are the three primary components of a cell. The cell membrane encloses the cell and regulates the molecules that enter and exit it.

His theory: Cells make up all plant tissues, and an embryonic plant is made up of just one cell. He declared that the cell is the fundamental building block of all plant matter.

Louis Pasteur- 1855 - German physiologist, physician, pathologist; and anthropologist. Added a third to the cell theory: Omnis Cellula e cellula (all cells develop only from existing cells).- Implied that there was no Spontaneous generation.

Rudolf Virchow- In 1862 he conducted a famous experiment supporting the theory that cells can only come from other cells.

His experiment:

Steralized flasks with straight and curved necks were used to heat nutrient broths. Bacteria only developed in the straight necks because bacteria cells from the air settled in the S-shaped necks' curves. Spontaneous gen did not produce proven cells in the broth.

kondor19780726 [428]

Complete question:

A geneticist crossed fruit flies to determine the phenotypic ratio. The geneticist crossed a fly with blistery wings and spineless bristles (bbss) with a heterozygous fly that had normal wings and normal bristles (BbSs). Which proportion of offspring that are dominant for both traits in would you not expect based on Mendel's law of independent assortment? 1/2 , 4/16, 25% , or 1/4

Answer:

1/2 is the proportion of the offspring that is NOT expected among individuals that are dominant for both traits.

4/16 = 1/4 = 25% of the progeny and the correct expected proportion of individuals that are dominant for both traits.

Explanation:

<u>Available data</u>:

  • Cross:  a fly with blistery wings and spineless bristles with a heterozygous fly that had normal wings and normal bristles
  • Recessive trait: blistery wings and spineless bristles
  • Dominant trait: normal wings and normal bristles

Let us say that:

  • B is the dominant allele for normal wings
  • b is the recessive allele for blistery wings
  • S is the dominant allele for normal bristles
  • s is the recessive allele for spineless bristles

Parentals)        bbss       x        BbSs

Gametes)  bs, bs, bs, bs     BS, Bs, bS, bs

Punnett square)    BS        Bs         bS        bs

                     bs    BbSs    Bbss     bbSs    bbss

                     bs    BbSs    Bbss     bbSs    bbss

                     bs    BbSs    Bbss     bbSs    bbss

                     bs    BbSs    Bbss     bbSs    bbss

F1)  4/16 = 1/4 = 25%  of the progeny is expected to be BbSs, dyhibrid individuals, expressing normal wings and normal bristles

     4/16 = 1/4 = 25% of the progeny is expected to be Bbss, expressing normal wings and spineless bristles

     4/16 = 1/4 = 25% of the progeny is expected to be bbSs, expressing  blistery wings and normal bristles

     4/16 = 1/4 = 25% of the progeny is expected to be bbss, expressing  blistery wings and spineless bristles

Cells differentiate because they need to become specialized. Which is an NOT example below of how specialized cells have unique
Elanso [62]
The only answer that is not an example of a cell specialization is : 
<span>Bacteria cells are small in size in order to easily diffuse in and out of the cytoplasm. 
All of the other examples, the muscle, nerve and the rod and cone cells have specific cell structures, shapes, and proteins that enable them to execute their specific roles in the organism. </span>
