This is known as imbibition GLOSSARY imbibitionthe taking up of liquid, causing swelling. Water hydrates enzymes in the seed, activating them. As a result the seed begins to release energy from its food store for growth.

Which answer choices are assumptions within the kinetic theory of matter?
kicyunya [14]

The correct options are:

  • Matter is made of small particles.
  • Matter's particles are in constant random motion or vibration
  • There is empty space between matter's particles.

Anything which has mass and occupies shape is a matter. Matter is composed of particles. The particles of matter are very small in size and they  attract each other. There is space between the particles. The particles are in continuous random motion, thus they have kinetic energy. on absorbing energy their movement increases.

Why would different restriction enzymes cut the same DNA molecule into different numbers of fragments
Nataly_w [17]

Because different restriction sites are used by different restriction enzymes to cleave DNA.

<h3>What is restriction sites?</h3>
  • A restriction site is a segment of DNA with a base pair count between 6 and 8 that binds to a certain restriction enzyme. There are numerous restriction enzymes that have been identified from bacteria. By cleaving the viral DNA, they naturally render invasive viruses inactive.
  • Restriction enzymes are beneficial in a variety of contexts. Each organism has a unique DNA sequence, so each one will have a unique arrangement of restriction sites.

In pea plants, round seeds are dominant to wrinkled seeds. If you cross two heterozygous plants, what would your ratios be for g
Mila [183]

Answer:

Genotype - RR - 25%, Rr - 50%, rr - 25% (1:2:1)

Phenotype - Round seeds - 75%, Wrinkled seeds - 25% (3:1)

Explanation:

Let the letter "r" stand for the alleles, where R is round seeds and r is wrinkled seeds. A genotype is an individual's genes represented through alleles. Phenotypes are how the genes express themselves. In other words, genotypes will be written using letters, the alleles, and phenotypes will be the possible outcomes of the alleles.

To find the ratios/percentages of the genotypes and phenotypes you can use a punnet squares. Both of the parent seeds have the genotypes Rr and the phenotype of round seeds.

If you create punnet square (which had four boxes in total) 1 will have RR, 2 will have Rr, and 1 will have rr. These are the ratios for the genotypes. Each box represents 25%, so the percentages will be 25, 50, and 25. Finally, 3 of these boxes (RR and Rr) will result in round seeds because those are domiant. Only the genotype rr will result in wrinkled phenotype. Therefore, the ratio is 3:1 or 75% to 25%.
