Answer:
B. An incoming charged tRNA binds to this site.
Explanation:
This is part of a process called TRANSLATION, in which mRNA is translated into proteins by the ribosomes, it comprises 3 stages: Initiation, Elongation, and Termination.
The A site is part of the ribosome, which has 1 binding site for mRNA and 3 binding sites for tRNA: A: Aminoacyl or acceptor site; P: Peptidyl; E: Exit, and it´s involved in ELONGATION, where it binds to the Aminoacyl tRNA (charged tRNA), that has the aminoacid that´s going to be added.
The answer is C. large changes in allele frequencies can occur in a short time.
Genetic drift is a change in the frequency of alleles in a population as a result of random sampling of organisms and it decreases genetic variation of the population. In specific circumstances, large and rapid changes in allele frequencies can occur in a short time. The smaller the population, the more susceptible it is to genetic drift.
Answer:0.5 g/cm
Explanation:
calculate the density : we'll use the formula below
density = volume over mass
Usually, density will have units of
g
m
L
when dealing with a liquid or units of

when dealing with a solid.
The mass has units of grams,
g
.
The volume can have units of
m
L
or
c

3
We are given the mass and the volume, both of which have good units. All we have to do is plug the given values into the equation:

Answer:
You are correct it's the earth!
Explanation:
The reason why is because, the term "elliptical orbit" is used in astrophysics and astronomy to describe an oval-shaped path of a celestial body. The Earth, as well as all the other planets in the Solar System, follow this type of orbit around the Sun. The shape is created by the varying pull of forces, such as gravity, on two objects, such as the Sun and a planet.
Hope this helps! :)
