3. Which of the following are NOT types of microorganisms?
timofeeve [1]

Answer:

d. Earthworms

Explanation:

Think about it: have you ever actually seen a prion, virus, or bacterium? No, because they can't be seen with the naked eye. Microorganism means that it's too small (hence the prefix micro-) to see.

  • Prions are little misfolded proteins. Viruses are nonliving things made up of a protein and nucleic acid. Bacteria are little prokaryotic microorganisms.

What is the most likely result of a cell with a mutation in the gene that codes for the enzyme primase?
Andreyy89

Answer:

The consequences will depend on the type of mutation. For example, if the mutation is synonymous it will not have negative effects on the cell function. On the other hand, if the mutation produces amino acid diversity it may cause loss of function

Explanation:

Primase is an RNA polymerase that adds RNA nucleotides to the complementary DNA strand in order to prepare it for the RNA polymerase III during transcription initiation

HELP ASAP<br> Punnett Squares
pashok25 [27]

Answer: The genotype ratio of offsprings of a cross between one homozygous tall plant and one heterozygous tall plant is 2TT:2Tt

The phenotype ratio is that all offsprings will be tall.

The genotype ratio of a cross between two heterozygous red flowers is 1RR:2Rr:2rr. The phenotype ratio is 3 Red flowers: 1 white flower.

Explanation: From the information given, tall is dominant and short is recessive while red is dominant and white is recessive.

Let T represent the allele for tall height, t represent the allele for short height, R represent allele for red flowers and r represent allele for white flowers.

The genotype of a homozygous tall plant is TT, the genotype of a heterozygous tall plant is Tt, the genotype of a heterozygous red flowered plant is Rr.

The possible genotypes of offsprings of a cross between one homozygous tall plant and one heterozygous tall plant are TT and Tt.

Tt will manifest outwardly as tall because T is dominant over t. Therefore, all the offsprings will be tall.

The possible genotypes of a cross between two heterozygous red flowers are RR, Rr and rr. RR will manifest as red, Rr will also manifest as red because R is dominant to r while rr will manifest as white because white allele (r) is recessive. Therefore 3 plants will be red-flowered while 1 plant will be white flowered.

See the attached punnet squares for details of the cross.
