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.
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 .

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.
Some people think hydropower should be used to supply all of the electricity

this plan?
A. Hydropower contributes to the greenhouse effect.
L
B. Hydropower can be used only in the desert.
C. Hydropower is used only as transportation fuel.
D. Hydropower can harm native aquatic populations.
Answer:
D. Hydropower can harm native aquatic populations.
Explanation:
Hydropower is the power of water or hydrosphere and is the cheapest and simplest form of energy. The hydrosphere is a renewable source of energy and is thus non-polluting but most of the hydropower that is converted into electricity is harmful to the marine and aquatic life forms. As it disturbs their habitats and created chemical and physical change in the body of water. Such as depletion of oxygen and enrichment of nutrients.what do you know about energy and cells?
Answer:
Cells do not use the energy from oxidation reactions as soon as it is released. Instead, they convert it into small, energy-rich molecules such as ATP and nicotinamide adenine dinucleotide (NADH), which can be used throughout the cell to power metabolism and construct new cellular components.

urinary bladder
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.

Answer:
CELL
Explanation:
1. Why does the moon go through Phases?
I
2. Why do we experience solar and lunar eclipses?
3. What is the underlying reason the Earth goes through
Seasons?
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.
