fomenos3 years ago
4 0

<span>Mitochondria and chloroplasts are the result of the process called endosymbiosis. Mitochondria and the chloroplasts are originally from the prokaryotes. They have the ability to take up inside a large single cell organism which they help each other in order to produce energy for each other. Endosymbiosis, from the term symbiosis, the organisms that are symbiotic is living inside the other pair, just like how the mitochondria and chloroplasts responds to each other.</span>

Why is redi's experiment a good example of a controlled experiment
Step2247 [10]
A controlled experiment is when the experimenter can change one variable in the experiment and completely change the results.

Redi experiment involved a closed jar with rotting meat on the inside. He waited for a few days and found no new forms of life in the jar.
He then did the same experiment, but this time he took the lid off the jar. After those few days he found there were maggots in the rotting meat from flies.

This is a great example of a controlled experiment, because he only had to change one variable to completely change the results. In this case that variable was just removing the lid from the jar.

Redi was trying to prove spontaneous generation with his experiment. Although, it failed.

Spontaneous generation: When life forms from non-livings.

Redi disproved spontaneous generation, but proved biogenesis.

Biogenesis: When life comes from other living beings.

He proved biogenesis because the flies had reproduced when the jar was opened.

What is bacteria flagellum? What is made of and its function? What type of organization can flagella have on cells?
Nadusha1986 [10]

Answer:

Bacterial flagella is the external structure that is thin, long and filamentous. It is attached to the cell wall of the bacteria which helps in the locomotion of the bacteria. It has three parts a filament, hook and basal body. The basal body is incorporated in the cell membrane.

A flagellum is made up of a protein called flagellin. It is a rigid protein and helps in making the hollow core of the filament by assembling together to form a structure which is cylindrical in shape.

The organization of flagella on bacterial cells is helpful in the identification of bacterial species. Mostly 4 type of organization of flagella is present on bacterial cell that are monotrichous, amphitrichous, lophoyrichous and perithrichous.

In monotrichious bacteria, only one flagella is present on one side, in amphitrichous both side of the cell have an equal amount of flagella. Lophotrichous bacteria have a group of flagella at one side of the cell and amphitrichous bacteria have many flagella distributed equally on its cell.

Bengal Tigers (Panthera tigris tigris) have coat colors that are either golden (the dominant trait) or white. In examining a pop
Hoochie [10]

Answer:

5%

Explanation:

Frequency of white tigers = 4%

population of tigers = 200

number of heterozygotes = 10

<u>Determine the actual genotype frequency of Heterozygotes </u>

frequency of heterozygotes = Number of heterozygotes / population

= ( 10 / 200 ) * 100

= 0.05 * 100 = 5%

The new Hazard Communication Standards provide teachers and students the right to __________ chemical hazards.
Aleonysh [2.5K]

The new Hazard Communication Standards provide teachers and students the right to manipulate chemical hazards.

Chemical hazards are non-biological substances that can cause damage to health. These are used in different enterprises, companies, school, universities and laboratories for different purposes such as cleaning, disinfection, scientific experiments, among others. When handling them, <u>employees are exposed to them and are vulnerable to harm from these chemicals</u>.  

There are many types of hazardous chemicals to be wary of, such as:

  • Carcinogens
  • Neurotoxins
  • Acids
  • Systemic toxins
  • Asmogens
  • Silica dust
  • Lead

In the workplace, exposure to these substances represents a real occupational hazard and there must be regulations to ensure that they are safe to handle.

The Occupational Safety and Health Administration (OSHA) is the agency of the U.S. Department of Labor which determined the Hazard Communication Standards. <u>This is a document with the necessary information to study the hazards of the chemical substances used by different employees in the companies</u>, so that they are aware of the dangers of these substances. These employees have the right to know exactly what compounds they handle and the risks involved in their use as well as the precautions and care to be taken.

Therefore, by having these safety standards in place in schools and universities, teachers and students have the possibility and the right to handle chemical hazards safely to be able to conduct the class normally and learn what is necessary.
