Answer: a) The single base change mutation occurs at the beta chain of haemoglobin when glutamic acid is replaced with valine.
b) Sickle Cell Anemia is inherited in an autosomal recessive pattern.
Explanation:
Haemoglobin is a protein found in the red blood cells whose main function is to transport oxygen. Sickle Cell Anemia is a disorder caused by a base change in DNA beta chain of haemoglobin. The amino acid valine is substituted for glutamic acid at one point in each of the two beta chains. When this type of hemoglobin is exposed to low oxygen, it forms elongated crystals inside the red blood cells that are sometimes 15 micrometers in length. These make it almost impossible for the cell to pass through many small capillaries, and the spiked ends of the crystals are likely to rupture the cell membrane, leading to sickle cell anemia.
In describing the inheritance patterns of sickle cell anaemia, it is of autosomal recessive pattern. This means that the parent of the affected individual both carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition. The gene for normal red blood cell is dominant over the gene for abnormal red blood cell which is said to be recessive. A person who is a stickler should have the genotype SS.

How was osmosis used to stop Clark’s seizures?
Answer:
after Clark was treated with a hypertonic solution? increased Na concentration in matrix of brain caused water from blood to move in to the brain which increased the matrix pressure. Pressure caused the neuron firing rate to increase which increased the likelihood of seizures.
Explanation:
hope this helps :)
The osmosis used to stop Clark’s seizures should be considered as the hypertonic solution.
Usage for stopping the Clark’s seizures:After clark it was treated with the hypertonic solution.
Here Na concentration should be increased in matrix of brain that leads to water from blood for moving in brain that increased the matrix pressure.
hence, The osmosis used to stop Clark’s seizures should be considered as the hypertonic solution.

Please help Why must animals eat food but plants do not eat food?(1 point) Plants do not appear to eat, but they do actually eat nutrients in the soil. Animals must eat to obtain food that they can't get from the soil. Plants make their own food through photosynthesis, so they do not eat. Animals eat because the energy they make themselves is enough to live but not grow. By eating, they can grow big and strong. Plants use photosynthesis to make their own food instead of eating. Animals eat plants because they like the taste of certain fruits. Plants make their own food through photosynthesis. Animals must eat because they cannot make their own food.
Answer:
Because they will die if they don't eat food, they need the protein to keep them moving and there muscles strong. Some animals get food off of other animals.

Explanation:
what species of organism does the gene donor cell belong to?
Answer:
Prokaryotes, which include bacteria and single-celled microorganisms called Archaea, usually pass their chromosomal DNA on to their offspring asexually. In other words, a bacterial cell reproduces by simply replicating its chromosome and dividing into two daughter cells. The daughter cells that result from this division are genetically identical to each other and to the original parent cell. Thus, over time, asexual reproduction in bacteria can lead to a population of hundreds of thousands of cells, all of which are genetically identical to a lone original parent cell.
Given their asexual method of reproduction, it is tempting to think that bacteria are sorely lacking in genetic variation, but this is not the case. Prokaryotic cells have developed a number of methods for recombining their genetic material, which, in turn, contributes to their genetic diversity. The three most common ways that bacteria diversify their DNA are transformation, conjugation, and transduction. However, not all types of bacterial cells are capable of engaging in all three processes.

Which of the following is a disadvantage to using chlorine for disinfection of water?
Answer:
Damage our health.
Explanation:
The levels of chlorine used for disinfection of drinking water causes long-term health effects because chlorine is toxic substance that greatly damaged cells and tissues of our body. Chlorine has low protection against protozoa due to its ineffectiveness on the protozoans organisms. These protozoa also adversely affected our health so we can say that chlorine has to be used in a limit which does not harm our body.
Answer:
Chlorine reacts with organic compounds.
Explanation:
Chlorine reacts with organic matter to create chlorination byproducts which often change the overall chemical properties of water.

What do you think could make the magnetic force produced by the launcher system so much stronger in the Wednesday launch than in the Tuesday launch, even though the spacecraft was moved the same distance closer?
If I were you only answer this if you do amplify
Answer:Magnetic forces are stronger closer to magnets. The Wednesday test launch stored more potential energy, and launched the spacecraft at a faster speed because the stronger magnetic field closer to the magnet resulted in a greater increase in potential energy.
