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)
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.
what is the significance of a chemical formula?
Answer:
The significance of chemical formula is that it tells us a lot about the chemical reaction

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.

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.

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.

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 cattle, a single gene with two alleles determines fur color. The fur can be red, white, or roan. Roan fur has both red and white hair. Which of the following is true about alleles for fur color in cattle?
The allele for roan fur color is dominant over red and white fur color.
The allele for red fur color is dominant over white and roan fur color.
The roan and white alleles are expressed independently of the other.
The red and white alleles are expressed independently of the other.
Answer:
D
Explanation:
D the red and white alleles are expressed independently of each other. You know this because roan is when both red and white are present. So therefore, because of this, the cow can be red, white, or both depending on what alleles are present.

explain how the population of octopuses and seaweed in this ecosystem might be affected if a disease reduced the crab population
Answer:
Seaweed might start to grow out of control withough crabs eating it, octopuses on the other hand would struggle to find food and start to die off because they relie on crabs to be their food source.
Without crabs to consume it, seaweed would start to grow out of control; octopuses, on the other hand, might struggle to find food and begin to disappear because they depend on crabs as a food supply.
What is the role of seaweed and octopus in ecosystem?
Seaweeds are important components of marine ecosystems. They serve as the primary source of nutrients and energy for marine organisms.
Either directly when fronds are consumed or indirectly when decomposing sections break down into small particles that are ingested by filter-feeding species.
No other creature has a predatory function as significant as that played by octopuses in forming communities.
Therefore, the population of octopuses and seaweed in this ecosystem might be affected if a disease reduced the crab population.
