Answer:
He examined covered and uncovered meat to determine that maggots came from eggs.
Explanation:
Prior to Redi's experiment and other supporting experiments, it was formerly believed that life could emanate from non-living things, for example, the generation of maggots from rotting meat.
In 1668, a scientist called Francesco Redi disproved the idea of spontaneous generation. He did this when he experimented that the maggots from meats are only as a result of eggs laid by flies when they perched on the meat.
He placed the meat in two jars; an uncovered jar and another in a covered jar with a cloth, after several days, the uncovered jar had maggots on the meat, while the covered jar had no maggot on the meat, but on the cloth. With this experiment, he was able to demonstrate that the maggot arose from the eggs of the flies, not the meat itself which is nonliving and hence, disproved the idea of spontaneous generation.
Answer:
9:3:3:1
Explanation:
A dihybrid cross tracks two traits. Both parents are heterozygous, and one allele for each trait exhibits complete dominance *. This means that both parents have recessive alleles, but exhibit the dominant phenotype. The phenotype ratio predicted for dihybrid cross is 9:3:3:1. (There's a calculator on google that show the outcomes just to let ya know) hope it's correct .
<h3><u>Comparison between Galapagos penguin and cold adapted Emperor penguin of Antarctica:</u></h3>
<u>Galapagos penguin:</u>
- Galapagos penguins are the only species of penguins that live north of the Equator.
- The Galapagos penguins breed all-round the year.
- The Galapagos penguins are smaller compared to the cold-adapted emperor penguins of Antarctica.
- The breeding and nesting place of the Galapagos penguins lie on the shoreline.
<u>Emperor penguin:</u>
- The emperor penguins live and adapt to the cold Antarctic environment.
- The Emperor penguins breed only during the Antarctic winters.
- The nesting of emperor penguins is on ice cliffs and icebergs where the eggs are protected from the strong and cold Antarctic winds.
- However, both of these species of penguins are at risk of extinction due to the rise in temperature and shortage of foods.
Answer: close ended
Explanation:
In a job oriented interview both open and closed ended questions are asked to the job seeker. The open ended interview questions are generally very long answer type questions these questions allows the person to express. These questions are asked to learn about the personality and interests of the job seeker. The closed ended questions are the short questions and they are easy to answer and these can be answered in yes and no. These questions are asked and answered quickly. The chances of mistakes in these questions are more. The chances of misinterpretation of the question is always more in these questions. But these questions allow to get more information about the candidate as compared to the open ended questions as during the open ended question session the job seeker can manipulate the facts but in the case of close ended questions the asking tendency is rapid so no manipulation can occur.
