Answer:
all the time
Explanation:
The radioactive wolves is a documentary film made on the Chernobyl radioactive disaster. This place is known as the Chernobyl exclusive zone and human trespasses is prohibited here.
A team of scientist went to the Chernobyl exclusive zone to do some research on the life of the wild animals in that place after the disaster. A large number of animals now are carrying particles of radioactive elements in their body and is roaming in the forests of the world.
So the scientist visiting the exclusive zone must wear the protective gears all the time they are in the place so as to prevent themselves from exposing themselves to the radio active elements.
Experiment Title: Does soil pH affect the color of tomato fruits?
A. Thesis statement: A high soil pH yields red tomatoes.
Set up: 9 pots each filled with soil of varying pH will be used in this experiment. The pots will be assigned into three groups: The control group will contain soil that has a neutral pH, the basic group will contain soil that has a pH greater than 7, and the acidic group will contain soil that has a pH lesser than 7.
The amount of water and sunlight received by the groups should be equal to eliminate other factors that could possibly affect the color variations. By keeping these factors the same, color variation would solely depend on the pH of the soil.
Control Group: It is necessary to keep the soil pH of the neutral group to be exactly 7. By making it neutral, we would be able to know what the natural color is exhibited by the tomato fruits.
The dependent variable in this experiment would be the color exhibited by the tomato fruits. The color exhibited is believed to be dependent on the pH of the soil. By having three samples each with varying pH, it is expected that there will be color variation.
Data Collection:
When the tomato plants bear fruits, determine the color of the fruits produced from each group. Create a table with two columns: the first column would be the group where the fruit belongs and the second column would be the color exhibited. Compare the data gathered from the three groups.
Data analysis:
A scenario which will support your hypothesis would be: the group which contained the basic soil produced red tomatoes. The neutral group produced orange tomato fruits while the acidic group produced yellow tomato fruits. It was found out that the higher the soil pH, the fruit color takes on a redder hue whereas if the pH keeps on going down, the fruit takes on a yellow a hue.
Solar system
Planets orbit around the Sun.
It is defiantly not a, because only part of the park was burnt. It wouldn't be c, because fire does not cause seeds to fly in. I would say B
Answer:
C.
Explanation:
In the context of evolutionary biology, coevolution refers to the evolution of at least two species, which occurs in a mutually dependent manner. ... An example is the coevolution of flowering plants and associated pollinators (e.g., bees, birds, and other insect species)
