Describe why Alleles occur in pairs?

Biology
1 answer:
Arada [10]3 years ago
3 0

Answer:

Alleles occur in pairs because chromosomes come in pairs for each trait, there will be two possible alleles. These different versions of genes (alleles) occur as the DNA base sequence is different. This combination of alleles for each trait is called the genotype; this can be any combination of two of the available alleles.

Ike is conducting a scientific experiment involving clear adhesive tape.
Nezavi [6.7K]

Answer:

see if the strips repel each other when brought close together

Explanation:

Electric fields can exert forces on objects, even if the objects involved are not touching. One way to demonstrate that electric fields exist around charged objects is to observe the effects of their forces at a distance.

Since Ike knows that each strip of tape carries a negative charge, he could see if the strips repel each other when brought close together.

What is the most important factor that determines the rate of diffusion in biological systems?
miv72 [106K]
The factors that determines the rate of diffusion in the biological system include: temperature, size of the particles, diffusion distance and concentration gradients. Of all these factors, the most important  one is the TEMPERATURE.
The relationship between temperature and the rate of diffusion is a direct one, that is, the higher the temperature the higher the rate of diffusion and vice versa. At high temperature the molecules in the particles move faster because they have higher amount of energy.
