Urinary bladder is the last structure to contact sperm before it leaves the body.

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.

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

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.

Knowing how to pair bases, we can fill the RNA molecule boxes.

                                     A ⇒ 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.  

Two primary agents of cellular communication are hormones and chemicals produced by nerve cells.

Cellular communication is a stepwise process that affects the generation of an extrinsic signal, detection of the signal by a receptor, transduction of the signal by intracellular signalling molecules and cellular response. When the extrinsic signal is removed, cellular communication processes cease.

Thus,  hormones and chemicals are two primary agents of cellular communication.

Explanation:

1.The Moon has phases because it orbits Earth, which causes the portion we see illuminated to change. The Moon takes 27.3 days to orbit Earth, but the lunar phase cycle (from new Moon to new Moon) is 29.5 days. The Moon spends the extra 2.2 days "catching up" because Earth travels about 45 million miles around the Sun during the time the Moon completes one orbit around Earth.

2.

An eclipse is the result of the total or partial masking of a celestial body by another along an observer's line of sight. Solar eclipses result from the Moon blocking the Sun relative to the Earth; thus Earth, Moon and Sun all lie on a line. Lunar eclipses work the same way in a different order: Moon, Earth and Sun all on a line. In this case the Earth's shadow hides the Moon from view.Lunar and solar eclipses occur with about equal frequency. Lunar eclipses are more widely visible because Earth casts a much larger shadow on the Moon during a lunar eclipse than the Moon casts on Earth during a solar eclipse. As a result, you are more likely to see a lunar eclipse than a solar eclipse.

3.Why Do We have Seasons?

As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons. When the earth's axis points towards the sun, it is summer for that hemisphere. When the earth's axis points away, winter can be expected. Since the tilt of the axis is 23 1/2 degrees, the North Pole never points directly at the Sun, but on the summer solstice it points as close as it can, and on the winter solstice as far as it can.

Why Do the Seasons Change on Earth?

Two things cause the seasons to change. First, the Earth moves around the Sun. Second, the Earth has a tilted axis of rotation.

The Earth spins around an axis. This imaginary line extends from the South Pole to the North Pole. But the Earth’s axis is not vertical. It’s actually tilted at an angle of 23.5°. The planet is always tilted in the same direction as it orbits the Sun.

Answer:

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.

Explanation: Lesser pandas are more genetically similar to raccoons that they are to giant pandas.

The statement "Lesser pandas are more genetically similar to raccoons than they are to giant pandas" is not fully supported by the information in the dendrogram presented above.

While it is true that the dendrogram suggests that the giant panda and lesser panda share a more recent common ancestor than either does with the other bears or the raccoon dog, it does not provide evidence to support the claim that the lesser panda is more genetically similar to raccoons than to giant pandas.

The dendrogram provides evidence for the evolutionary relationships among these organisms based on their DNA and RNA sequences. It suggests that these organisms have a common evolutionary history and can be grouped together based on their molecular data.

However, it does not provide information on the degree of genetic similarity between any two specific organisms or groups of organisms.

Therefore, while it is possible that the lesser panda may be more genetically similar to raccoons than to giant pandas, this claim cannot be fully supported by the information in the dendrogram alone.

Further analysis of genetic data and comparison of specific genetic sequences would be necessary to determine the degree of genetic similarity between these organisms.
