Answer:
Analyzing data and drawing conclusions
Explanation:
The scientific method is a process or method of inquiry that follows a series of sequential steps which helps a scientist to understand the world around him, draw conclusions and predict results.
The steps in the scientific method include:
1. Observation: the scientist observes his environment keenly and carefully.
2. Asking a question to identify the problem.
3. Conducting research to get information about the problem.
4. Making a hypothesis or an educated guess of a possible outcome.
5.Conducting experiments to test the hypothesis.
6. Analyzing data and drawing conclusions: this involves drawing inferences about experimental results and determining if the collected data supports the original hypothesis and determining if the hypothesis is correct.
7. Communicate results: presenting the result and data through various media, such a laboratory report.
Answer:
C. Parasitism
Explanation:
Mutualism means both organisms benefit. An example of this is a bee and flower.
Commensalism means one organism benefits and the other is unaffected. An example of this is a whale and barnacles.
Parasitism means one organism benefits, and the other is harmed. An example of this other than mosquito and human is a dog and fleas.
Hope this helps!!
A) They are different states of matter.
Answer:
Atomic radius of sodium = 227 pm
Atomic radius of potassium = 280 pm
Explanation:
Atomic radii trend along group:
As we move down the group atomic radii increased with increase of atomic number. The addition of electron in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus size of atom increased.
Consider the example of sodium and potassium.
Sodium is present above the potassium with in same group i.e, group one.
The atomic number of sodium is 11 and potassium 19.
So potassium will have larger atomic radius as compared to sodium.
Atomic radius of sodium = 227 pm
Atomic radius of potassium = 280 pm
Answer:
D.phototropism
Explanation:
Phototropism is a type of tropism in which a plant or plant part responds to light. According to this question, a student wanted to investigate the effect of light on the growth of cress seedlings. The student used three different pots for the experiment.
Pot 1 was placed with light from above. Pot 2 was placed in a cupboard with no light. Pot 3 was placed in a window with light from one direction only. However, the image attached to this question shows that the plants in the different pots face different directions in response to light, which depicts phototropism
