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 .

In guinea pigs, short fur (S) is dominant to long fur (s). Two heterozygous guinea pigs
(Ss) mate. Complete the Punnett square and then list the percentages of the
expected genotypes for their offspring.
Explanation:
A way I like to remember heterozygous is by remembering that the other word for heterozygous because brainly wont let me say it apparently. The same gender liking each other, so (word) is same, hetero is different.
each square would have 25% each because 100%÷4=25.
Dominant one is like mixing black and blue together,the black is gonna give a dark effect to blue so black is dominant.
Blue is recessive.
The percentage of the Ss is 75% while the percentage of the ss is only 25%.
Performing a crossGiven that we have the genotypes of the both parents as Ss. The Ss imples that the gene for short fur is dominant over the gene for long fur.
Now, when we perform te cross for the first generation, we will discover that we have the offspring; Ss, Ss, Ss and ss. The percentage of the Ss is 75% while the percentage of the ss is only 25%.

Some people think hydropower should be used to supply all of the electricity
for the United States. Which of the following statements describes a flaw in
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.If an air mass is sinking, it must be
A. cold and less dense
B. warm and more dense
C. cold and more dense
D. warm and less dense
Answer:
The awnser to your question is C.
Explanation:
The colder matter is the atoms get closer therefore making the matter more dense. A. is half correct but if the matter is cold it wouldn't be more dense because when something is less dense it goes above whatever is around it. Take for example water and oil. They seperate into different layers due to density. Hope this helps. :)
The airmass is a large homogenous mass of air over a region that could be for many days.
The volume of air is defined by the temperature and water vapor content. Airmass may spread from hundreds to miles and are classified according to latitude and altitude. There are 4 types of air mass artic, tropical equatorial, and polar. The airmass that is light is warm and has a low pressure always lifts upwards. The cold and cool airmass always settles as it's dense and heavy. Hence the option C is correct.Learn more about the air mass is sinking, it must be.

Imagine that the cell is exposed to some kind of stressor such as extremes of temperature, exposure to toxins, or mechanical damage. The chain reactions will be
Disruption or the formation of cell membrane blebsAlteration of protein synthesis and accumulation of altered proteins in the ERAlteration of the chromatin of the chromosomes inside the nucleus and DNA damageAlteration of the permeability of organelles such as mitochondria with consequent alterations in metabolismDecrease in ATP levels and increase in cytoplasmic calcium levelThe combination of all this can lead the cell to death but it can respond in various ways:
the cell can decrease protein synthesis and induce the transcription of specific stress-sensitive chromosomal genes that correct altered proteinsIt can respond to DNA damage by stopping replication and trying to repair it If it cannot survive it can commit suifcide so as not to harm other cellsdescribe an environment factor that could affect the growth of an organism
The main factor that affects the growth of a organism is the pollution caused by factories and wastes as well as harmful gases released.

In patients infected with nonresistant strains of the tuberculosis bacterium, antibiotics can relieve symptoms in a few weeks. However, it takes much longer to halt the infection, and patients may discontinue treatment while bacteria are still present. How could this result in the evolution of drug-resistant pathogens?
The bacteria are still present and may obtain antibiotic resistance to spread to other species by horizontal gene transfer.
Antibiotics have become diluted and weak because of a limited supply.
Bacteria have purposefully directed their immune system to resist the effect of the antibiotic.
Resistant bacteria are polyploidy and can resist the antibiotic, a trait that is passed on to their offspring.
Answer:
The bacteria are still present and may obtain antibiotic resistance to spread to other species by horizontal gene transfer.
