Answer:
This occurs at the 3′ end position which sits on an mRNA, while a distinct tRNA anticodon triplet sequence matches a three complementary base pair mRNA codon sequence to guide appropriate amino acid into place at a ribosome activation site to form a polypeptide or protein.
The interaction between codon and anti-codon is occurs at the 3′ end position which sits on an mRNA.
What are the functions of mRNA?Messenger ribonucleic acid is a single-stranded molecule of RNA that corresponds to the genetic sequence of a gene, and is read by a ribosome in the process of synthesizing a protein.
The role of mRNA is to carry protein information from the DNA in a cell's nucleus to the cell's cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates each three-base codon into its corresponding amino acid.
Found in all cells, messenger ribonucleic acid, or mRNA, is a single-stranded molecule. It is responsible for transferring genetic information from DNA, found in the nucleus of the cell, to ribosomes floating in the cell's cytoplasm.

Mistakes are sometimes made in duplicating or transmitting genetic information. These mistakes are called
Answer:
Mutation
Explanation:
Mutation is any alteration or change in the genetic sequence of a gene caused by mutagens (substances) or mistakes during replication of genetic sequences.
A mutation occurs in the gene from time to time, although, the cell has protocols in place to put them under control if they occur. However, when DNA or a gene is being copied and transferred to offsprings, there is bound for mistakes called MUTATION to occur.

What causes ocean tides to reach higher up on a shore at certain times of day than at others? A. The moon's gravity and Earth's rotation B. The ocean's conveyor belt and refraction C. Earthquakes and volcanoes O D. Temperature and salinity differences
Answer:
A
Explanation:
I read about ocean tides. the Moon has an effect on the ocean which causes the ocean to bulge toward the Moon. When the Moon is in alignment with the sun the ocean bulges out more because of the added gravity. The Moon though smaller than the sun has more gravitational pull than the sun.

How do volcanoes provide evidence to scientists to support the idea that matter and energy move within the Earth’s interior?
Answer:
Scientists use volcanic activity data from this area to show the relationship between volcanic activity and lithospheric plate motion. Hot Spots and Plate Tectonics: A volcanic hot-spot is an area in the mantle from which heat rises in the form of a thermal plume from deep within the Earth. Higher heat and lower pressure at the base of the lithosphere melts rock and forms magma.

c. Suppose a large population of turtles consists only of two species, snapping turtle and box turtle, but the percentage of the species in the population are unknown. What is the maximum possible value of the diversity index D for the population
Answer:
[tex]D_m=1/2[/tex]
Explanation:
From the question we are told that
2 species
Assuming that questions a and be are solved
Diversity index D=2p_1p_2
with [tex]p_1 +p_2 =1[/tex]
Mathematically
[tex]D=2p_1(1-p_1)[/tex]
[tex]D=2(p_1-p_1^2)[/tex]
[tex]D=2({\frac{1}{4} -(p_1-1/2)^2}[/tex]
Therefore
[tex]D=\frac{1}{2} -2(p_1-1/2)^2[/tex]
Giving
[tex]D_m=1/2[/tex]
[tex]p_1=1/2[/tex]

If two hybrid tall pea plants are crossed what is the probability that the offspring will have the tall phenotype?
Answer:
There is a high probability that the Pea plant will have a High phenotype!
Explanation:
Because both "parent plants" are tall, this will cause the offspring to also be tall, this will be because it in it's genes or in other words DNA too be strong.
The mass of a cylinder of beetroot was 2.5 g. If its final
mass was 2.7 g, what was the
increase in mass in per cent?
Answer: The percent increase in the mass of cylinder of beetroot is 8%.
Explanation:
To calculate the percent increase in the mass of cylinder, we use the equation:
[tex]\%\text{ increase in mass}=\frac{\text{Final mass - Initial mass}}{\text{Initial mass}}\times 100[/tex]
We are given:
Final mass of the cylinder = 2.7 g
Initial mass of the cylinder = 2.5 g
Putting values in above equation, we get:
[tex]\%\text{ increase in mass}=\frac{2.7-2.5}{2.5}\times 100\\\\\%\text{ increase in mass}=8\%[/tex]
Hence, the percent increase in the mass of cylinder of beetroot is 8%.

C. When blood sugar concentration is above normal, the endocrine system releases hormones that lower the blood sugar concentration until it reaches a normal level, and the release of the hormones slows.
D. When a person is jogging, the body releases hormones that continually decrease the rate of oxygen supply to the legs.
ANSWER is A
When blood sugar concentration is too low, the endocrine system secretes hormones that increase blood sugar concentration to a normal level.

Answer:
light moths
Explanation:
yes their were most light color in most trees
Light moths was more common before the 19th century, when most trees were light in color.
What are the functions of light moths?Insects, like moths, are drawn to bright lights because they make it difficult for them to navigate. It's a common sight, particularly in the summer: The lights, like lamps, were surrounded by moths and other insects.
Most nocturnally dynamic moths are drawn to light, a peculiarity known as sure phototaxis. However, because they are phototactic, some species, like the Old Lady (Mormo maura), tend to avoid it.
No one really knows why moths are drawn to light, but there are a few theories, and they also like the smell of fermented sugar and ripe fruit, which are both food sources.

All of the following are true of spermatogenesis EXCEPT: Question 4 options: One spermatogonium produces 4 spermatids Genetically diverse spermatids are created. The products are spermatozoa that each have a head, midpiece and tail. DNA replicates once, but cells divide twice. Spermatids containing 23 chromosomes (1n) are produced.
Answer: The products are spermatozoa that each have a head, midpiece and tail.
Explanation:
The spermatogenesis can be defined as the process of gamete production in human males. It takes place in the testes in males. In this process the spermatids are produced which are four in number through reductional cell division called as meiosis. Each spermatid is haploid in number and the genetic material present in each is diverse as a result siblings are not identical to each other. The spermatozoa is an immature sperm cell which develops head, middle piece and tail. But it is not a precursor of production of sperm cells via cell division.
