What does it mean if there are two different alleles for a trait ?

Biology

AURORKA [14]3 years ago
7 0

Answer:

The trait is heterozygous.

Explanation:

Heterozygous: "Having two different alleles of a particular gene or genes."

A heterozygous genotype looks like: Rr. The capital R is a dominant allele, and the lowercase r is a recessive allele. These two alleles are not the same (not two dominant alleles or two recessive alleles) meaning that the trait is a heterozygous trait.

The opposite of a heterozygous trait is a homozygous trait, in which both alleles are the same (both dominant or both recessive) and can look like RR or rr (genotype-wise).

Mkey [24]

Answer:

The correct answer to the question is: 1) free in the cytoplasm.

Explanation:

  • Ribosomes are responsible for synthesising polypeptide chains by the process of translation from mRNA or messenger Ribonucleic Acid.
  • They are found free in the cytoplasm or remain bound to the Endoplasmic Reticulum (ER) to form the Rough Endoplasmic Reticulum (RER).
  • The cytoplasmic proteins are synthesised by the free ribosomes.
  • The membrane proteins, secretory proteins and the organelle specific proteins are synthesised by the Ribosomes located on the Endoplasmic Reticulum.
  • This is because these proteins need to be translocated to the target organs through vesicles that buds out of the ER and and the Golgi bodies.
  • As the luciferase polypeptide is located in the cytoplasm, it is synthesised by the free ribosomes present in the cytoplasm.

If 8.0g of H2 reacts and 72g of H2O is produced how much O2 is consumed in the reaction
Lady_Fox [76]

Answer:

  64 g of O₂ is consumed in this reaction.

Explanation:

  Mass of H₂O = 72 g

  Mass of H₂ = 8 g

  So, mass of O₂ consumed = mass of H₂O - mass of H₂ = 72 - 8 = 64 g

   64 g of O₂ is consumed in this reaction.
