Given the choice of 4 bases and the number of bases needed to make up a codon, how many possible codons are there? 16 23 64 128
Answer:
64
Explanation:
A codon is a group of three nucleotide sequence in a mRNA that specifies a particular amino acid acid. There are only four nucleotides composed of the four nitrogenous bases viz: Adenine, Guanine, Cytosine and Thymine/Uracil.
A codon is composed of only three of these nucleotide bases at a time. Hence, considering the number of nucleotide bases that can make up one codon and the 4 nucleotide bases, there can only be 4^3 = 64 combinations of the four nucleotides. This means that there are 64 possible codons.
During an earthquake, what is the most destructive type of seismic wave that caused a rolling motion?
1. P waves
2. S waves
3. Surface waves
4. Transverse waves
Answer:
Surface Waves
Explanation:
Surface waves cause more damage because they produce more ground movement and travel slowly, which makes it take longer to pass.
During an earthquake, the most destructive type of seismic wave that caused a rolling motion is known as a Surface wave. Thus, the correct option for this question is C.
What is an Earthquake?An earthquake may be defined as a sudden trembling of the surface of the earth. It causes great destruction, as a result of movements within the earth's crust or volcanic action. The circumstance of an earthquake is fatal to living organisms.
According to the context of this question, surface waves are those waves that significantly cause more threats to the surface of the earth. they effectively construct more ground trembling and movement. These waves travel gradually and this makes it take longer to pass.
Therefore, during an earthquake, the most destructive type of seismic wave that caused a rolling motion is known as a Surface wave. Thus, the correct option for this question is C.

Will give brainlist ! 6. Explain what happens to the forces of gravity when:
a. Two masses are moved further apart
b. Two masses are moved closer together
Answer:
a. When two masses are moved further apart from each other, the gravitational force between them will be weaker. They will not have a large effect on each other.
b. However, when two masses are moved closer together, the gravitational force between them will grow stronger (a prime example of this is the Sun's gravitational force on the Earth). The larger the mass is, the higher effect it will have on other bodies of mass.
How would plant populations be affected if the populations of decomposers,
such as earthworms, decreased dramatically?

O C. Plant populations would be unaffected by changes in the
earthworm population.
D. Plant populations would flourish because they would not need to
compete with the worms for nutrients.
pleaseee helppppp
Answer: B. plant population would suffer because the soil would have fewer available nutrients.
Explanation:
Earthworms are called a farmer's best friend as they make the soil more fertile. When earthworms purify the soil it makes it easier for the plants to grow as the soil is mineral rich. Decrease in the population of earthworms would make it difficult for the plants to grow because of the less fertile soil.
