Answer: Sickle-cell Anemia, Beta hemoglobin (beta globin)
Explanation: For example, sickle-cell anemia is a disease caused by the smallest of genetic changes. Here, the alteration of a single nucleotide in the gene for the beta chain of the hemoglobin protein (the oxygen-carrying protein that makes blood red) is all it takes to turn a normal hemoglobin gene into a sickle-cell hemoglobin gene. This single nucleotide change alters only one amino acid in the protein chain, but the results are devastating.
Beta hemoglobin (beta globin) is a single chain of 147 amino acids. As previously mentioned, in sickle-cell anemia, the gene for beta globin is mutated. The resulting protein still consists of 147 amino acids, but because of the single-base mutation, the sixth amino acid in the chain is valine, rather than glutamic acid.
Sickle-cell anemia is an example of a mutation in the beta-globin gene that changes the phenotype of a red blood cell.
What is Mutation?Genetic alterations might result in a condition like sickle-cell anemia. Here, a normal hemoglobin gene may be converted into a sickle-cell hemoglobin gene by changing a single nucleotide in the gene encoding the beta chain of the hemoglobin.
A single chain of 147 amino acids makes up beta-globin, often known as beta-hemoglobin. The beta-globin gene is mutated in sickle-cell anemia, as was already noted.
The resultant protein still has 147 amino acids, but due to the single-base mutation, valine rather than glutamic acid makes up the sixth amino acid in the chain.
Therefore, only one amino acid in the protein chain is altered by this one nucleotide mutation, but the consequences are disastrous.

Which of the following best explains why cells that contain the same genetic material do not develop into the same types of cells?
A. Because chemical signals that are released during the cell cycle can result in the linking of similar genes
B. Because internal or external stimuli can trigger the activation of specific genes in the DNA of cells
C. Because messenger RNA is converted to transfer RNA when cell differentiaton begins
D. Because random mutations can occur in the DNA of cells during early embryonic development
The statement 'internal or external stimuli trigger the activation of specific genes in the DNA of cells' BEST explains why cells having the same genetic material do not develop into the same cells (Option B).
Cell specialization refers to the process by which common stem cells differentiate to produce specialized cells that perform specific functions.Cell specialization is caused by differential gene expression patterns that lead to the expression of different proteins in different types of cells.For example, hematopoietic stem cells differentiate into red blood cells to transport oxygen in the blood by expressing the hemoglobin gene, whose protein binds to oxygen.In conclusion, the statement 'internal or external stimuli trigger the activation of specific genes in the DNA of cells' BEST explains why cells having the same genetic material do not develop into the same cells (Option B).

Helppppp please What characteristic of water
means that clear water is not
necessarily clean water?
A. the density of the water
B. high specific heat capacity
C. the temperature of the water
D. ability to act as a universal solvent
Answer:
B
Explanation:
Ability of water to act as a universal solvent means that clear water is not necessarily clean water. Therefore, option (D) is correct.
What is clean water?Clean, safe water is defined by the USGS as "water that won't hurt you if you come in touch with it." Although drinking water is often mentioned when discussing clean water, clean water is also crucial for all residential uses.
It is impossible to smell, taste, or even see the microscopic contaminants that pollute water, such as bacteria, viruses, and parasites. Therefore, just because your water is clear doesn't imply it's okay to drink.
Therefore, due to the fact that water is a universal solvent, meaning that it is capable of dissolving a wide range of substances with relative ease clear water is not considered clean.

a football plyer throws a ball with a mass of 0.34kg what is the gravitational potential energy of the ball when it is 5.0 m above the ground?
Answer:
17 J
Explanation:
PE=mgh=0.34x10x5=17
The potential energy is defined as the energy that is present in a resting body. It is 17J.
What is the other form of energy in any moving objects ?It is the kinetic energy that is present in the moving objects. It is just possessed by the moving objects.
PE= mgh where m stands for the mass of a body where it is the matter that is contained inside a container, g stands for the gravity under which effect the body comes down back to the Earth which has value of 9.8 and h is the height that is the distance covered by the body in the vertical manner.
When 0.34 is multiplied with 9.8 and 5.0 the answer is 17 J that is the energy that is possessed by the resting body which is not undergoing any kind of motion and not going through any kind of disturbance in the motion.

In natural selection, organims that are well suited for their environment tend to survive and reproduce. WHen organisms reproduce, they pass their characterisitcs on to their offspring through their genes. Organisms with characters not well suited for their environment are not as likely to survive to reproduce and pass on their characteristics. Organisms that are not able to reproduce and pass on their traits to their offspring die off, or become extinct.
