Choose the CORRECT statement concerning the cell membrane lipid molecules
VashaNatasha [74]

Answer:

The correct statement concerning the cell membrane lipid molecules is that "energy is not expended during diffusion" (Option d)

Explanation:

Biological membranes are formed by two lipidic layers arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, and their hydrophobic tails against each other. Membranes are fluid, which means that molecules that form it have the capability to move through it.  

Lipids can easily change places with other neighbor lipids by <u>lateral diffusion</u> in the same layer. This is passive diffusion, which means that it does not need energy to happen.

Lipids can also diffuse transversally to the other layer, but this kind of movement is not as easy as lateral diffusion.

There are also other lipidic movements as rotational diffusion that imply the rotation of the molecule.

Through this lipidic bilayer, there is also a passive transport of some particles from one side of the cell to the other which happens because of concentration differences.

What is the probability of a pea plant with genotype rryy producing a gamete with genotype ry?
andrew-mc [135]

The probability of a pea plant with genotype rryy producing a gamete with genotype ry is 1.

<h3>What would be the probability of a pea plant producing genotype ry from the genotype rryy?</h3>

  • Probability is a measurement used in genetics to forecast the likelihood that a desired trait will be acquired by a child. The most easiest way to calculate the probabilities is to make a punnet square.
  • The genotypes of a specific cross or breeding experiment are predicted using the Punnett square, a square diagram. It bears Reginald C. Punnett's name, who developed the method in 1905. Biologists use the figure to calculate the likelihood that a child will have a specific genotype.
  • If we employ a punnet square for the genotype rryy producing a gamete with genotype ry the probability would be 1. You can refer the diagram for the understanding of the punnet square.
  • F1 genotype: rryy
  • F2 genotype: ry ry ry ry
  • Thus the probability would be 1.
