(a) Tyr-Gly-Arg-His
(b) Met-Pro-Ala-Val
(c) Tyr-Gly-His
(d) Met-Pro-Val
The sequence of amino acid for the given mRNA code is Methionine-Proline-Valine.
What is a codon?It is a trinucleotide sequence of RNA or DNA, which corresponds to a particular amino acid. The genetic code illustrates the association between the DNA base sequence within a gene and the corresponding sequence of protein, which it encodes.
The sequence of the gene is read based on the groups of three bases. In total there are 64 distinct codons, of which 61 codes for amino acids and the rest three are used as stop signals. On seeing the mRNA code AUGCCAGUAUG, it can be seen that,
AUG codes for methionineCCA codes for prolineGUA codes for valineUG is not a codonTherefore, the correct amino acid sequence will be Methionine-Proline-Valine.

15 POINTS Imagine that you are playing in a basketball game. Write 3-5 sentences
describing different forces observed during the game. Remember, any time an
object's motion changes, there must be some kind of force acting on it.
Answer:
A friction force occurs in the shoes that are played and the floor of the court.When the ball spins, a centripetal force occurs that prevents the ball from moving away from the center of its rectilinear motion. The weight force allows the ball to fall back to the ground because without it it would be suspended in the air, it would not bounce, which would make basketball an impossible game.Which of these provides evidence from developmental blology of a shared evolutionary history?
a. the dna sequences of the cytochrome c genes in chimpanzees and spider monkeys are over 90% identical
b. the skeletal structure of a leg of a horse and a flipper of a whale are very similar
c. both snakes and dogs have pelvical bones even though they are vestigial structures of the snake
d. both lobsters and frogs go through metamorphosis as a process in their life cycle
Answer:
b
Explanation:
The evidence from developmental blology of a shared evolutionary history is both snakes and dogs have pelvical bones even though they are vestigial structures of the snake and the correct option is option C.
Snakes and dogs belong to different evolutionary lineages, yet both possess pelvical bones, which are vestigial structures in snakes. The presence of these bones in both species suggests a shared ancestry and evolutionary history.
This indicates that their ancestors once had functional pelvic structures, but over time, snakes lost the need for them and they became reduced and non-functional.
The presence of vestigial structures in different species indicates a common ancestor with a shared developmental pathway, supporting the idea of shared evolutionary history.
Thus, the ideal selection is option C.

What is mutation?A mutation, as stated in this question, is an alteration in the nucleotide sequence of a gene, which can alter the gene product. In this question, each sentence is made up of three‑letter words, representing mRNA codons. The sentences are:
THE FAT CAT SAT
THE CAR WAS RED
SHE HAS THE DOG
A substitution mutation is that mutation involving the replacement of a nucleotide by another in a sequence. In the sentence; THE CAR WAS RED, R letter was replaced by letter T, hence, the sequence/sentence changed to THE CAT WAS RED.
An insertion mutation involves the addition of a nucleotide into the original sequence. In the sentence/sequence; THE FAT CAT SAT, letter A was added in between "fat" and "cat" to change the sentence to THE FAT ACA TSA T.
Deletion mutation involves the removal of a nucleotide from an original sequence. In the sentence/sequence; SHE HAS THE DOG, letter O was removed from the sentence to change it to SHE HAS THE DG.

1-Paragraph that explains an example of natural selection . (3-5 sentences)
Answer:
In a habitat there are red bugs and green bugs. The birds prefer the taste of the red bugs, so soon there are many green bugs and few red bugs. The green bugs reproduce and make more green bugs and eventually there are no more red bugs.
Answer:Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment.For example, tree frogs are sometimes eaten by snakes and birds. Gray Tree frogs blend well in dark wooded areas on tree bark and Green Tree frogs blend in well with green vegetation found in marshes and swamps. A Green Tree frog on the bark of a tree is easier for a predator to find, compared to a Green Tree frog on a green leaf. So, Green Tree frogs that go into habitats where they are not camouflaged are more likely to be eaten by predators. Since Tree frogs that have been eaten do not live to have any more baby Tree frogs, natural selection has favored Tree frogs that live in habitats in which they are more camouflaged.
What are three ways body systems work together to maintain homeostasis?
Answer:
Each organ system performs specific functions for the body, and each organ system is typically studied independently. However, the organ systems also work together to help the body maintain homeostasis.
For example, the cardiovascular, urinary, and lymphatic systems all help the body control water balance. The cardiovascular and lymphatic systems transport fluids throughout the body and help sense both solute and water levels and regulate pressure. If the water level gets too high, the urinary system produces more dilute urine (urine with a higher water content) to help eliminate the excess water. If the water level gets too low, more concentrated urine is produced so that water is conserved. The digestive system also plays a role with variable water absorption. Water can be lost through the integumentary and respiratory systems, but that loss is not directly involved in maintaining body fluids and is usually associated with other homeostatic mechanisms.
Similarly, the cardiovascular, integumentary, respiratory, and muscular systems work together to help the body maintain a stable internal temperature. If body temperature rises, blood vessels in the skin dilate, allowing more blood to flow near the skin’s surface. This allows heat to dissipate through the skin and into the surrounding air. The skin may also produce sweat if the body gets too hot; when the sweat evaporates, it helps to cool the body. Rapid breathing can also help the body eliminate excess heat. Together, these responses to increased body temperature explain why you sweat, pant, and become red in the face when you exercise hard. (Heavy breathing during exercise is also one way the body gets more oxygen to your muscles, and gets rid of the extra carbon dioxide produced by the muscles.)

is it B,C, OR D???
The answer is C; Many copies of a DNA Fragment
The specific DNA sequence has been doubled. This cycle of Denature-Anneal-Extend is repeated, usually about 35 times, by using a thermocycler over 2-3 hours (the "chain reaction" of PCR). This produces 34,359,738,368 copies of DNA (That's 2^35)!
PCR is a technique used which is used to amplify DNA so, many copies of a DNA fragment will get as a end result of using PCR.
What is DNA?DNA stands for deoxyribose nucleic acid.It is a self-replicating substance that makes up the majority of chromosomes in practically all living creatures. It carries genetic information of living beings.What is PCR polymerase chain reaction?Kary B. Mullis, an American scientist, invented PCR in 1983.The polymerase chain reaction (PCR) is a laboratory technique used for rapidly amplifying millions to billions of copies of a single DNA region.PCR entails selecting a portion of the genome to be amplified using short synthetic DNA fragments called primers, followed by several rounds of DNA synthesis to amplify that segment.Amplification is accomplished by a three-step process:-Denaturation is the process of heating double-stranded DNA templates to separate the strands at 95°C.Annealing is the process of short DNA molecules called primers binding to flanking regions of target DNA at 55°C.Extension is the process of DNA polymerase extending the 3′ end of each primer along the template strands at 72°C.These processes are performed 25–35 times to make precise copies of the target DNA exponentially.
Hence, the correct option is D.

The D string on a violin has a frequency of 293 Hz when it is in tune. Calculate the period.
Answer:
Answer:The Time (period) is 0.003 s
Step-by-step explanation:
The period is equal to Time.
the formula for calculating Time (period) is:
Time (period)= 1/frequency
frequency= 293 hz
Time (period) = 1/293
= 0.003
If The D string on a violin has a frequency of 293 Hz when it is in tune, its period is equal to 0.003 s.
What is period?The period is the length of time required to finish a circuit. The inverse of this, or the amount of cycles in a second, is frequency. The wavelength is the distance that sound moves in one period.
Time is equivalent to the period.
Time (period) is calculated using the following formula:
Period (time) Equals 1/frequency
Frequency=293 hertz
Period (time) Equals 1/293
= 0.003 s
As an illustration, if a newborn baby's heart pulses 120 times per minute, its period—the space between beats—is half a second 60 seconds divided by 120 beats.
Therefore, the period is the reciprocal of the frequency because it is the length of time for one cycle in a repeating occurrence.

Note that the evidence shown on the map that indicates point B is most likely experiencing precipitation is the front represented by the line with bumps moving from low to high pressure.
On the map, the indication that point B is likely experiencing precipitation is the presence of a front represented by a line with bumps moving from low to high pressure.
This front typically denotes a transition zone where warm and cold air masses meet, leading to atmospheric instability and potential precipitation. As the front advances, it often brings changes in weather conditions, including cloud formation, rainfall, or other forms of precipitation, affecting areas along its path such as point B.
