What does it mean that a hypothesis must be testable? can a hypothesis be proven unquestionably true? why or why not?

katen-ka-za [31]

A testable hypothesis must be just that--testable. You must be able to provide evidence that your hypothesis can be proven true in order for it to be considered accurate enough for future use among scientists. This can be done through repeated experimentation.

1. How does the cell membrane allow animals to move without rupturing the cells in the body?

oksian1 [2.3K]

Explanation:

1)The cell membrane functions as a semi-permeable barrier, allowing a very few molecules across it while fencing the majority of organically produced chemicals inside the cell. Electron microscopic examinations of cell membranes have led to the development of the lipid bilayer model (also referred to as the fluid-mosaic model). The most common molecule in the model is the phospholipid, which has a polar (hydrophilic) head and two nonpolar (hydrophobic) tails.

2) simple diffusion across the cell plasma membrane. The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down the concentration gradient is , by simple diffusion.

3) some molecules, such as carbon dioxide and oxygen, can diffuse across the plasma membrane directly, but others need help to cross its hydrophobic or however, because they are charged the polar, they can't cross the phospholipid part of the membrane without help .

4) during fission a copy of the DNA is made and attached to the cell membrane as well. As this cell elongate in preparation for fission, the two DNA copies are pulled apart two opposite ends of the cell. New membrane material is deposited between the two ends of the cell, and a new wall grows between them .

6) example of passive transport and active transport across a cell membrane so, cell membranes are semipermeable meaning they have control over what molecules can or cannot pass through. Some molecules can just drift Inn.

In the couple described in Problem, the woman gives birth to a color-deficient but otherwise normal daughter. The husband sues f

Rashid [163]

Answer:

See the answer below

Explanation:

From the problem, color is X-linked. Males have just one (XY) chromosome while females have two (XX). Hence, for a recessive trait, males will need only one allele to be affected while females will need two alleles.

Dominant form allele for normal vision = C

Recessive form allele for color deficiency = c

Genotype of a man with normal color vision = $X^CY$

Genotype of a woman with color deficiency = $X^cX^c$

Crossing the two:

$X^CY$ x $X^cX^c$

$X^CX^c$ $X^CX^c$ $X^cY$ $X^cY$

normal female normal female affected male affected male

(a) All their sons would be affected for color deficiency. Hence, the probability of them having a color-deficient son is 100% or 1.

(b) None of their daughters is supposed to be affected for color deficiency. Hence the probability of them having a color-deficient daughter is 0.

If the woman gives birth to a color-deficient but otherwise normal daughter and husband sues for a divorce on the ground of adultery, the case will definitely stand up in the court because none of their daughters can be affected for color deficiency based on genes of the man and the woman.

In order to produce an affected daughter, the father will need to supply an affected X chromosome in conjunction with the one that will be supplied by the woman.

In this case, the man does not have an affected chromosome, hence it is not possible for them to have an affected daughter except that the woman slept with another man who happens to have an affected X chromosome.
