Answer:
1) RNA strand = UCA GCA AAU
2) Amino acids: Asparagine Arginine Stop
(ASN) (ARG) (STOP)
Explanation:
Some theory that you need to know to answer the question:
Each tRNA has two important sites. One of them that couples with the codon of the mRNA molecule, named anticodon. The other site couples with an amino acid through the action of the aminoacyl-tRNA synthase enzyme. The whole complex, amino acid + enzyme + tRNA is named aminoacyl-tRNA. Considering that there are twenty amino acids available, there are also twenty complexes of aminoacyl-tRNA, one for each amino acid.
tRNA allows amino acids to align according to the nucleotidic sequence in the mRNA molecule.
Once the new amino acid joins the growing peptidic chain, the binding between the amino acid and the tRNA molecule breaks. The tRNA is now free to join another amino acid and repeat the cycle.
Now, to fill in the boxes, you need to pay attention to two things:
• Anticodon: In this box, you need to place the sequence of bases that pairs with the mRNA codon.
• Amino Acid: In this box, you need to place the amino acid that is codified by the mRNA codon.
For instance, let us say that the codon of mRNA is CUC. The anticodon for this sequence is GAG (because guanine joins cytosine and adenine joins uracyl).
The amino acid places on the 3´extreme of the tRNA molecule will be the one that is codified by the codon, NOT the anticodon. So, as the codon is CUC, the amino acid will be Leucine, Leu. Do not use the anticodon GAG to fill these boxes. Remember that tRNA is translating information carried by the mRNA, so we need to use this information to grow the protein.
1)
Strand of DNI → AGT CGT TTA
Each of these letters are bases → Adenine, A - Guanine, G - Thymine, T - Cytocine, CEach of these three-lettered groups are codons.So, we need to pair these bases, knowing that:
Adenine (A) and guanine (G) derive from purines, while Thymine (T) Uracile (U), and Cytosine (C) derive from Pyrimidines.
In the DNA molecule, Adenine (Purine) always pairs with Timine (Pyrimidine), while Guanine (Purin) forms pairs with Cytosine.
In the RNA molecule, Adenine is paired with Uracil, U. So, whenever there is an Adenine in the DNI strand, it pairs with Uracil of RNA strand. If there is a Thymine in the DNI strand, it pairs Adenine of the RNA strand. And, as always, Guanine pairs with Cytosine.
A ⇒ UT ⇒ AG ⇔ CKnowing how to pair bases, we can fill the RNA molecule boxes.
Strand of DNI → AGT CGT TTAStrand of RNA → UCA GCA AAUA ⇒ U C ⇒ G T ⇒ A
G ⇒ C G ⇒ C T ⇒ A
T ⇒ A T ⇒ A A ⇒ U
2)
Now we need to translate these new codons of mRNA to amino acids.
To fill the boxes you should have a genetic code chart to see the codons that codify for each amino acid.
Codon: AAU CGA UAG
Amino acids: Asparagine Arginine Stop
(ASN) (ARG) (STOP)
The new protein is synthesized from the amino terminus to the carboxy terminus of the mRNA molecule. The added amino acids to the chain are coded by a codon formed by three bases in the mRNA. mARNs also have a start and end codon that are the signals of the synthesis initiation and finish. When the ribosome reaches a stop codon, protein synthesis is over.

A farmer uses DDT to kill insects in his field. The first year nearly all of the insects were killed. By the fourth year, however, nearly all of the insects survived the DDT treatment. Explain the process of natural selection in this population of insects. Include these words - mutation, phenotype, variation, resistance, adaptation, and differential survival.
Answers
Answer:
Explanation:
Selection is the greatest force that alters gene frequency and brings about variation that is evidence in a population. There are both natural and artificial selection.
Mutation is one of the force that alters population frequency it is an heritable change that is sudden and occur in the gene, it can be induced or caused naturally.
The insect survived the DDT used because over the years they have build immunity and resistance against the chemical, they now mutate and produce gene that becomes resistance to the chemical and now adapted or adaptable to the environment. Natural selection helps in the continuous perpetuation of the new phenotype and a new differential survival rate.

A. little rainfall
B. little wind
C. soil with little organic matter D. few large animals
Answers
Answer:
12. C. slight temperature range
13. B. little wind
Explanation:
Grassland biomes do not have a slight temperature range, they have a large one. It could be very hot in the day time but then quite cold at night.
Deserts do not have little winds blowing across them. These winds are usually strong and dry. The sand dunes in deserts were formed by these winds as they pick up sand particles and carry it to another area.
Which is the last structure to contact sperm before it leaves the body?
penis
sperm duct
testes
urinary bladder
Answers
Answer:
A is correct
Explanation:
Urinary bladder is the last structure to contact sperm before it leaves the body.
What are the functions of urinary bladder?The urinary bladder, or simply bladder, is a hollow organ in humans and other vertebrates that stores urine from the kidneys before disposal by urination. In humans the bladder is a distensible organ that sits on the pelvic floor.
The urine formed by the nephrons of the kidneys is transported to the urinary bladder for storage before it gets expelled through the urethra. The urinary bladder is a sac that serves as a reservoir for urine.
The urinary bladder is a temporary storage reservoir for urine. It is located in the pelvic cavity, posterior to the symphysis pubis, and below the parietal peritoneum. The size and shape of the urinary bladder varies with the amount of urine it contains and with the pressure.

C - Natural selection is causing larger bird beaks.
E - Because the seed hardness has increased the birds need bigger beaks to crack them.
R - This means the birds with larger beaks are not able to crack the seeds, this causes starvation and the birds that have small beaks die as a result. However, birds with larger beaks are able to crack the seeds and eat. Those birds can then reproduce and produce more birds with larger beaks. So the population of large bird beaks has increased, but the population of small bird beaks has decreased.

In patients infected with nonresistant strains of the tuberculosis bacterium, antibiotics can relieve symptoms in a few weeks. However, it takes much longer to halt the infection, and patients may discontinue treatment while bacteria are still present. How could this result in the evolution of drug-resistant pathogens?
The bacteria are still present and may obtain antibiotic resistance to spread to other species by horizontal gene transfer.
Antibiotics have become diluted and weak because of a limited supply.
Bacteria have purposefully directed their immune system to resist the effect of the antibiotic.
Resistant bacteria are polyploidy and can resist the antibiotic, a trait that is passed on to their offspring.

In guinea pigs, short fur (S) is dominant to long fur (s). Two heterozygous guinea pigs
(Ss) mate. Complete the Punnett square and then list the percentages of the

Answers
Explanation:
A way I like to remember heterozygous is by remembering that the other word for heterozygous because brainly wont let me say it apparently. The same gender liking each other, so (word) is same, hetero is different.
each square would have 25% each because 100%÷4=25.
Dominant one is like mixing black and blue together,the black is gonna give a dark effect to blue so black is dominant.
Blue is recessive.
The percentage of the Ss is 75% while the percentage of the ss is only 25%.
Performing a crossGiven that we have the genotypes of the both parents as Ss. The Ss imples that the gene for short fur is dominant over the gene for long fur.
Now, when we perform te cross for the first generation, we will discover that we have the offspring; Ss, Ss, Ss and ss. The percentage of the Ss is 75% while the percentage of the ss is only 25%.
