The best answer would be:
A membrane bound nucleus
<u>Here is more about the question:</u>
There are three domains in the classification of organisms and they are Eubacteria, Archaea, and Eukarya. What makes Eukarya different from the other two is the presence of a nucleus in the cells. Among the remaining two, Archaea is more closely related to Eukarya than Eubacteria.
Temperature is a measurement of the average kinetic energy of the molecules
in an object or system.
Answer:
Number 3
Explanation:
Dominant: 20, Recessive: 20
An allele is the alternative of a gene. On his case, these beans represent the alleles for a simple Mendelian trait, where red is dominant (R) and white is recessive (r).
As states earlier there are 20 red beans (20 dominant alleles) and 20 white beans (20 recessive beans) and each beach represent an allele.
Question:All known organisms use genetic information to produce protein molecules via the same genetic code. This finding strongly supports the hypothesis that __________.
a) the earliest macromolecules probably arose when lightning struck an oxygen-free atmosphere
b) all organisms are descended from one or a few common ancestors
c) the genetic code readily evolves by natural selection
d) there's only one possible way to encode information in a macromolecule
Answer:
b) all organisms are descended from one or a few common ancestors
Explanation:
Protein synthesis occurs when the nucleotide sequence of the mRNA is read in the form of genetic codes. A specific genetic code specifies the same amino acid in all living beings. For example, the code "UUU" codes for phenylalanine in all the living beings irrespective of their species. This suggests that all the life forms have originated from one or few common ancestors and the genetic code has been preserved during the course of evolution of various species.
