Two short-haired guinea pigs have several offspring over the course of a few years. Out of 100 offspring, 25 of them have long hair. What are the probable genotypes of the parents
The genotype of the short-haired parents that produced some long hair offsprings is probably heterozygous.
What is heterozygosity?Heterozygous means an organism which has two different alleles of a given gene.
An organism that is heterozygous posseses two different alleles of the same gene. For example, in this gene coding for hair length;
L represents short hair (dominant)l represents long hair (recessive)Therefore, if two short-haired parents produce 100 offsprings and 25 of them are long-haired, it means that they were probably heterozygous for the short hair.

Which of the following
best explains the
difference between

occur in the summer
B. freezing rain usually occurs when no clouds are
present while snow only occurs when there are clouds
C. snow freezes in a cloud then falls to Earth while
freezing rain freezes after it hits a cold surface
D. there is no difference between snow and freezing rain
Answer:
answer a,b,c is the difference between snow and freezing rain
As water vapor in the sky condenses around minute dust or salt particles, snow is created as a type of precipitation. Ice crystals are created when the water vapor freezes around these particles. The correct option is C "Snow freezes in a cloud and then falls to Earth while freezing rain freezes after it hits a cold surface" is correct.
Snowflakes are created when these ice crystals group together. When snowflakes are too heavy to remain floating in the air, snow falls to Earth.
Raindrops that fall through a layer of cold air condense into freezing rain, which is a kind of precipitation. Raindrops freeze as they come into touch with cold surfaces, such as the earth. Since it may make sidewalks and roadways slick and ice, freezing rain can be extremely dangerous.

Explanation:
Why do plants contain the
greatest amount of energy in the
food pyramid?
Answer:
According to the pyramid of energy, the energy content is maximum in autotrophs or producers. Autotrophs are the plants which prepare their food by photosynthesis. They are the primary producers and primary source of food energy. The flow of energy is unidirectional from producer to consumer level.
Explanation:
According to the energy pyramid, autotrophs or producers have the highest energy content. Autotrophs are plants that prepare their nourishment through photosynthesis. They are the key producers and energy sources for food. Energy flows unidirectionally from producer to consumer.
What is an Energy pyramid?A trophic pyramid, also known as an ecological pyramid, is an illustration of the flow of nutrients through an ecosystem. It is a graphical representation of the proportions of energy available in an ecosystem at each trophic level, or feeding level.
The pyramid of energy is often divided into tiers, with primary producers, like power plants, at the bottom. Above the primary producers come the principal consumers, which include herbivores that eat plants. Then there are secondary consumers, like carnivores that eat herbivores, and so on.
Thus, according to the energy pyramid, autotrophs or producers have the highest energy content.
