Genetic variation among the gametes of one individual is most likely to
increase if crossing over
A. happens during meiosis I.
B. happens after meiosis II.
C. involves different species.
D. involves sister chromatids.
Answers
Answer:
A. happens during meiosis I.
Explanation:
In meiosis I, homologous pairs align independently on the equator. All possible combinations of chromosomes can occur among the gametes. Genetic variation is increased by crossing-over. (union of female and male gametes) produces random combinations.

how sunlight regulates the productivity of algae and the number of catfish in a pool.
Answers
Answer:
Algae produces food and catfish also needs warm water.
Explanation:
Sunlight regulates the productivity of algae and the number of catfish in a pool because algae produces food in the presence of sunlight during the process of photosynthesis. If algae produces more food, so more food is available for the catfish and as a result the population of catfish increases. If no sunlight occur on the pool the algae is unable to produce food and the population of catfish decreases. Sunlight increases the temperature of water which makes environment suitable for the catfish because catfish needs slightly warm water for its growth. So we can say that sunlight has a great affect on algae and catfish.

True/ False: Substances will diffuse more rapidly through a dense substance. Explain
Answers
Answer:
I'd say true
Explanation:
Mass of the molecules diffusing: Heavier molecules move more slowly; therefore, they diffuse more slowly. The reverse is true for lighter molecules. ... Because cells primarily use diffusion to move materials within the cytoplasm, any increase in the cytoplasm's density will inhibit the movement of the materials.
Answer:
False
Explanation:
As the density of a solvent increases, the rate of diffusion decreases. The molecules slow down because they have a more difficult time getting through the denser medium. If the medium is less dense, diffusion increases.
The statement, "the total mass of the product must equal the total mass of the reactants" is known as the ____
Answers
Answer:
The statement, "the total mass of the product must equal the total mass of the reactants" is known as the Law of conservation of mass.
Explanation:
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
This law was given by French chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
Consider the example of photosynthesis reaction:
6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂
There are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.

Which two parts of the water cycle involve water in its gas form?
A) Condensation and collection
B) Evaporation and condensation
C) Precipitation and condensation
D) Runoff and evaporation
Explain why.
Answers
Evaporation and condensation involve water in its gas form. Hence, option B is correct.
What is the water cycle?The continual movement of water on, above, and below the Earth's surface is referred to as the water cycle, also known as the hydrologic cycle or the hydrological cycle. It is a very important cycle for the survival of living organisms.
The water cycle is composed mostly of four processes: evaporation, convection, precipitation, and collection. When the water in rivers, lakes, or the ocean is heated by the sun and turned into vapor or steam, this process is known as evaporation. In condensation, water vapors are converted into water.
The parts of the water cycle that involve water in its gas form are evaporation and condensation. Hence, option B is correct.

Answers
Answer:
sunlight
Explanation:
Marine phytoplanktons are not found at great depths in the ocean because of the lack of sunlight at these depths.
Phytoplanktons need sunlight to survive. They utilize light for food production through photosynthesis. Without light, this process would become limited and the phytoplanktons will die of starvation.
At great ocean depths, sunlight penetration becomes limited and thus, phytoplanktons also stay away from these depths.

Answer:
d. Views could be used to make topographic maps of the area.
Explanation:
Satellite views helps the planners in choosing a location for the airport because it provides topographic maps of the area which contains all information about natural features of that area such as roads, railways, power transmission lines, contours, elevations, rivers and lakes. So the satellite images provides a great help to the planners to find out suitable place for the airport.
