Answer:
Takes 5 pots and apply water at different rates.
Explanation:
For determining the effects of water on seed germination, Lily have to used 5 pots having pumpkin seeds and apply different amount of water to the seeds of pumpkin. This experiment of providing different amount of water to the pumpkin seeds provides information that which plant germinate faster as compare to other seeds. Those seeds that receive suitable amount of water will germinate quickly as compared to those which receive very low or very high amount of water.
Some populations of Atlantic tomcod fish have an allele that makes the fish resistant to toxic pollutants called PCBs. Tomcod populations in several rivers were analyzed for the presence of this allele. Each river had varying levels of PCB pollution. Which of the following results would best support the conclusion that natural selection is influencing the presence of this allele in the tomcod populations?
A. All of the tomcod in each of the rivers have this allele.
B. The percentage of tomcod with this allele remains the same from year to year in each river.
C. The rivers with high PCB levels have larger percentages of tomcod with this allele than the rivers without PCBs.
D. Eggs from tomcod without this allele can hatch in rivers with or without PCBs, and eggs from tomcod with this allele can only hatch in rivers without PCBs.
Answer:
D
Explanation:
Hope it helps#CARRYONLEARNINGEggs from tomcod without this allele can hatch in rivers with or without PCBs, and eggs from tomcod with this allele can only hatch in rivers without PCBs.
What is Tomcod populations?A benthopelagic piscivore, the Atlantic Tomcod is also known as frostfish or tommy cod. Although large ones are allegedly caught less frequently than they once were in estuary rivers, it is still abundant around the seacoast.
Although anadromous, Atlantic tomcod do not migrate very far between fresh and salt water. In shallow brackish or fresh water, sand and gravelly bottoms are where eggs are laid. Masses of eggs sink to the bottom.
Within 24 hours of hatching, newly hatched larvae swim to the surface to breathe surface air before their pneumatic duct closes. Young-of-the-year may spend their first spring and summer in fresh or barely brackish water, but they eventually move into estuaries and nearshore waters.
Therefore, Eggs from tomcod without this allele can hatch in rivers with or without PCBs, and eggs from tomcod with this allele can only hatch in rivers without PCBs.

Why does the concentration of CO2 go up and down throughout the year?
the role of plants in carbon cycle
Explanation:
the amount of CO2 found in the atmosphere varies over the course of a year. much of this variation happens because of the role of plants in carbon cycle...respiration occurs all the time, but domains during the colder months of the year, resulting in higher CO2 levels in the atmosphere during those months.

X + H20 → Y + O2(what would be y in this equation ?)
Answer:
y. 2. • CxHy + O2 → x CO2 + y/2 H2O. Combustion Problem. Erythrose is an important mono-saccharide that is used in chemical synthesis. It contains Carbon.
Explanation:
In the chemical equation X + H₂O → Y + O₂, Y represents the product of the chemical reaction, here Y is the glucose, and this X is carbon dioxide, and this is a reaction of the photosynthesis.
What is photosynthesis?During photosynthesis, the energy from light is used to split water molecules into oxygen and hydrogen ions. The oxygen is released into the atmosphere as a waste product, while the hydrogen ions are used to create a chemical gradient across the thylakoid membrane within the chloroplast. This gradient is then used to power the creation of ATP, the energy currency of cells, as well as to reduce carbon dioxide to form organic molecules, such as glucose. The overall equation for photosynthesis is:
6 CO₂ + 6 H₂O + light energy → C₆H₁₂O₆ + 6 O₂
Hence, In the chemical equation X + H₂O → Y + O₂, Y represents the product of the chemical reaction; here, Y is the glucose.
