Which particles cannot pass through the cell membrane?

Biology
1 answer:
kolezko [41]3 years ago
7 0

The most important property of the cell membrane is its selective permeability: some substances can pass through it freely, but others cannot. Small and non polar (hydrophobic) molecules can freely pass through the membrane, but charged ions and large molecules such as proteins and sugars are barred passage.

There was a release of immense heat within the bodies as they collided together as gravitational potential energy was converted into kinetic energy of the individual gas particles and then collisions between these particles converted this energy into heat.

Therefore, a massive amount of heat was released.

A researcher crosses the F1 generation of two snapdragon plants. According to this information and the diagram below, what is th
Stels [109]

The correct answer is B. 1 red; 2 pink; 1 white

Explanation:

In genetics, the combination of alleles (genotype) determines the phenotype or physical features; for example, in this case, the color of the flowers in the snapdragon plants can be determined by the combination of dominant alleles (R) and recessive (r) alleles. Additionally, in the case presented, a dominant allele combined with a recessive allele (Rr) leads to pink snapdragon plants, while two dominant alleles (RR) lead to red snapdragon plants, and two recessive alleles (rr) lead to white snapdragon plants.

According to this, the generation F2 shown in the chart produced 1 red plant because there is only one plant with RR genotype; 2 pink plants because there are two plants with Rr genotype; and finally one white plant because the last plant has an rr genotype.
