What conclusion about photosynthesis is supported by the evidence from this experiment? Explain your reasoning.
more light means more photosynthesis means more oxygen
closer to light the more oxygen is produced
distance from light & oxygen produced is in an inverse relationship which means when one goes up the other goes down
According to the data on the table, when the distance from the light increased, the bubbles produced per minute have decreased. The relationship between the two variables shows an inverse one. This means that if one variable increases, then the other one decreases, and vice-versa. Using this information, we can conclude that when the aquatic plant is placed far from light, it gets less sun exposure. This affects the rate of photosynthesis, including its by-products. When the rate of photosynthesis is slow, the oxygen produced as a waste product is also low.

Some _____ become memory cells when exposed to an infection agent and, if they encounter the same antigen in the future, they can respond quickly to destroy the invader before it causes illness.
Answer: T cells and B cells
Explanation:
Memory cells are the type of immune cells that responds to the previously exposed infectious agent. B and T cells become memory cells.
What are B and T cells?B and T cells are antibody and cell-mediated immune cells respectively that are produced in response to the pathogens and fight the infectious agents that invade the body.
The cells differentiate into the same type and one in the form of the memory cell. The memory cells remember the infectious agent and respond quickly to the same antigen in a future invasion.
Therefore, B and T cells differentiate into memory cells.

Water stress occurs when the demand for water exceeds the supply. This is likely to occur in:
Question 19 options:
Rainforest, small towns, industrial areas
Wet ecosystems, Sparsely populated Countries, less intense agriculture
Naturally arid ecosystems, Heavily populated countries, Areas with intensive, highly-irrigated agriculture
Tundras, medium populated countries, cattle-farming
Answer:
C. is the correct answer!
Explanation:
If its a naturally arid ecosystem then there wouldn't be that much water there in the first place.
The more people means the more supplies its needed to support those people, which can also lead to supply shortages such as in water.
Highly irrigated agriculture can also lead to tons of water being wasted, needed, and used up.
Why is dna replication considered a semi-conservative process.
Answer:
This process is said to be 'semiconservative' because one strand from each parent is conserved and remains intact after replication has taken place.
Answer:
Because each DNA strand is made up of one "conserved" old piece of DNA and one new piece.
Explanation:
during DNA replication once the two strands are unzipped on strand is older an theater strand is new

what happens to the surface area to volume ratios as a cell gets larger?
Answer:
Smaller as the cell gets larger [Decrease]
Explanation:
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Therefore, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.
Assuming that the shape of the cell stays the same, if the cell increases it's linear dimension (length) by a factor of 2, the surface area will be increased by a factor of 4, and the volume will be increased by a factor of 8. You can verify that this is true with simple shapes such as spheres or cuboids.
The volume grows more rapidly than the surface area. Hence the surface area to volume ratio decreases.

what results from sea-floor spreading? please help
Answer:
The crust cracking.
Explanation:
Seafloor spreading is a geologic process in which tectonic plates—large slabs of Earth's lithosphere—split apart from each other. ... The less-dense material rises, often forming a mountain or elevated area of the seafloor.
Answer:
Seafloor spreading creates new oceanic crust at a mid-ocean ridge.
