An analysis of DNA and RNA sequences can be used to classify organisms. A dendrogram, such as the one shown below, is based on molecular data. It can be used to represent evolutionary relationships within a group of organisms that are hypothesized to have descended from a common ancestor. Brown bear Sun bear Spectacled bear Giant panda Lesser panda Raccoon Dog 100 0 So 60 40 20 Mulions of Years Ago 13 Which statement is best supported by the information in this dendrogram?
Answers
Answer: C
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.
What does the dendrogram suggest basically ?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.

All of the major components of the light reactions, including the pigment molecules
clustered in photosystems I and II, are located in the thylakoid membrane. What is the advantage of
having these components confined to the same membrane rather than dissolved in the stroma or the
cytosol/cytoplasm? Explain your argument. (up to 5 points)
Answers
Answer:
Having the light reaction components in close proximity speeds up the process. Electrons move from one protein to the next in sequence. If the proteins had to 'swim' around to find the next part of the electron transport chain, then the ATP would form at a much slower, inefficient rate.

1. If your child had a child with a man with sickle cell disease, predict whether that child
would also have sickle cell disease. Explain the reasoning and describe the information
you used to make your prediction.
Answers
Answer:
Sickle cell disease (SCD) is a blood disorder that a child is born with. It's passed down through a parent’s genes. Children with SCD make an abnormal type of hemoglobin. This is the protein in red blood cells that carries oxygen to all parts of the body. With SCD, the body organs and tissues don’t get enough oxygen.
Explanation:
Healthy red blood cells with normal hemoglobin are round and move easily through blood vessels. When a child has SCD, the red blood cells are hard and sticky. They are shaped like the letter C (and like a farm tool called a sickle). These damaged red blood cells (sickle cells) clump together. They can’t move easily through the blood vessels. They get stuck in small blood vessels and block blood flow. This blockage can cause pain. It can also damage major organs.
Sickle cells die sooner than healthy cells. Normally the spleen helps filter infections out of the blood. But sickle cells get stuck in this filter and die. Having fewer healthy red blood cells causes anemia. The sickle cells can also damage the spleen. Without a healthy spleen, children are more at risk for serious infections.
There are several complex types of the sickle cell gene. Some don’t cause symptoms or severe problems, but others do. Talk to your child’s healthcare provider about the specific form of sickle cell your child has.
Most children with SCD will start showing symptoms during the first year, often around 5 months.
Answer:
IN my opinion I dont really thinkthe child would have ssickle cell because the mother or father dont have it, its only one part of its family have it but if the one part of its family sickle cell jeans is storng thn yes the child may get it .

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.

Answers
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 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.
