Answer:
None
Explanation:
closely look at the tentacles of the fish. none of them has the same length.
thus no lines of symmetry
Petroleum is not a source of coal or coal-precursor.
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.
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.

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%.
