because the location of the ascospores (haploid cell of sordaria) within the ascus shows whether or not crossing over took place. since the formation of ascospores occurs within an ascus, all of the daughter cells are packaged together. if crossing over did not take place, four black ascospores are grouped together next to four tan ascospores. using this as a subject, scientist are easily and accurately able to determine whether or not crossing over occured.

Why do some organisms possess non-ideal traits?
Some organisms possess non-ideal traits due to genetic mutations, environmental pressures, or random chance during evolution. These traits may not be advantageous for survival or reproduction, but they can persist in a population if they do not significantly impact an organism's ability to survive and reproduce.
Is the optimum growth temp the ideal temp for all cell activities. based on observation of S.marcescens and S.cerevisiae cultures Explain?
The optimum growth temperature is the temperature at which a microorganism grows best, which may not necessarily be the ideal temperature for all cellular activities. In the case of S. marcescens and S. cerevisiae cultures, the optimum growth temperature may differ from the optimal temperature for other metabolic processes such as enzyme activity or protein synthesis. Different cellular activities may have their own optimal temperature requirements beyond just growth.
Why did mendel use pea plants in his experiment?
Mendel used pea plants in his experiment because they have distinct traits that are easy to observe and manipulate. Pea plants also have a relatively short life cycle which allowed Mendel to conduct multiple generations of controlled breeding experiments. This made it an ideal model organism for studying inheritance patterns.
What is the ideal human comfortable temperature range for indoor environments?
The ideal human comfortable temperature range for indoor environments is typically between 68 to 76 degrees Fahrenheit.
What is the ideal pH level of egg whites for achieving the best results in baking or cooking?
The ideal pH level of egg whites for best results in baking or cooking is around 7.6 to 8.0.
Why S fimicola an ideal organism for demonstrating crossing- over?
Sordaria fimicola is an ideal organism for studying crossing-over because it undergoes a visible change in genetic recombination during meiosis, which can be observed with a microscope. The fungus produces ascospores in a linear arrangement, making it easy to analyze and count crossovers. Additionally, the gene markers used in S. fimicola are stable and well understood, allowing for accurate mapping of the crossover events.
Why are fruit flies an ideal organism for organism research?
Drosophila(fruit flies) can produce plenty of offspring and have specific traits, such as eye color and body color/shape. They are easy to observe and therefore easily traced throughout the following generations.
How trilobite eyes indicated the environment they live in?
If the eyes were located toward the front of the head,the organism was probably an active swimmer.If the eyes were in the back of the head, the organism might have been an ocean bottom dweller. in most species,the eyes were located midway on the head-ideal for an organism that both crawled on the seafloor and swam in the water.
How do Trilobite eyes indicate how the Trilobite lived?

Why are fruit fies an ideal organism for genetic research?
Fruit flies are prolific breeders, have 4 pairs of chromosomes, and have easily distinguishable chromosomes.
What type of climate is ideal for moss?
Moss is a very hearty organism and thrives in humid areas. The best place for moss to grow is in forests and jungles, where precipitation and moisture is prevalent.
What role does temperature play in an?
Most organisms have an ideal temperature range in which they can live. If temperatures are too hot or too cold for any length of time, then the organism may not be able to survive.
Why do some organisms possess non-ideal traits?
Some organisms possess non-ideal traits due to genetic mutations, environmental pressures, or random chance during evolution. These traits may not be advantageous for survival or reproduction, but they can persist in a population if they do not significantly impact an organism's ability to survive and reproduce.
What organism grow best in a candle jar?
Organisms like mold and certain bacteria can grow well in a candle jar due to the warm and humid environment created by the burning candle. However, this is not a recommended or ideal environment for any organism to grow due to the presence of combustion by-products and potential fire hazard.
What slide organism in mitosis in plant cell?
The slide organism commonly used to study mitosis in plant cells is the onion root tip. Onion root tips have actively dividing cells that are easily observable under a microscope, making them ideal for studying the different stages of mitosis such as prophase, metaphase, anaphase, and telophase.
How does temperature affect the distribution of a plant?
Temperature greatly affects the distribution of organisms, especially in hotter countries, where they are less likely to find the water they essentially need to survive. Most organisms have a ideal/acceptable temperature range, where maximum population will flourish. If the temperature is outside of the ideal temperature range, the organism will be unable to survive and reproduce, meaning there will be no other organisms of the same species being produced, and therefore, no other organisms of the same species will be able to grow around the area where the original organism was.
What gases are not ideal and why?
Fartting is not ideal
