Throughout history, many unscientifically based claims have been made. One such claim was
that some people believed that fleas actually came from dust. Which part of the cell theory
provides a basis for disproving this claim?
Answer:
There are no options to this question, however, it can be answered. The answer is:
All cells arise from previously existing cells
Explanation:
The universal cell theory was proposed in 1830's by three scientists viz: Rudolf Virchow, Mathias Scleiden, and Theodor Schwann. The cell theory consists of three major components which are generally accepted and used till date. The components are:
- All living things are made up of one or more cells
- The cell is the fundamental and basic unit in every living thing.
- All cells arise from previously existing cells via cell division
According to this question, many unscientifically based claims including the believe that fleas actually came from dust have been made. This claim has been DISPROVED by the part of the cell theory that states that "All cells arise from previously existing cells via cell division". Hence, fleas do not arise from dust but from other cells according to cell theory.
It can be deduced that the cell theory that provides a basis for disproving this claim is that all cells are from existing cells.
What is a cell theory?It should be noted that a cell theory simply means that all biological organisms are made of cells.
In this case, some people believed that fleas actually came from dust. This was proved wrong as the cell theory states that all cells are from existing cells.

What is photosynthesis and chlorophyll?
Answer:
photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
chlorophyll is a green photosynthetic pigment found in plants, algae, and cyanobacteria. Chlorophyll absorbs mostly in the blue and to a lesser extent red portions of the electromagnetic spectrum, hence its intense green color.
Hey there!
Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunlight, so we eat plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae, and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the green pigment found in the chloroplasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.

What is it called when a whale has died and rested in the bottom of the ocean to provide nutrients for other animals and the soil?
Answer:
Decomposition.
Explanation:
Decomposition is the process in which dead or organic matter is broken down over time into simpler organic and inorganic matter. A whale resting at the bottom of the ocean will provide food for animals and restore nitrogen to the soil. Overtime, the whale will no longer exist. This is an example of decomposition.
Warmer water due to climate change might favor harmful algae in a number of ways: ... Warmer water is easier for small organisms to move through and allows algae to float to the surface faster. Algal blooms absorb sunlight, making water even warmer and promoting more blooms.
Answer:
See explanation
Explanation:
Actually, a warmer water is less dense than cold water. It follows that small organisms can easily move through a less dense water. Warm water allows algae to flow through it faster leading to an algal bloom facilitated by climate change.
The water will further be heated up by the fact that the increasing number of algae absorb sunlight thereby further increasing the temperature of the water. The foregoing explains the greater algal bloom in warm years.

proton
a glucose molecule
Next Question
Answer:proton,electron, helium atom,carbon 14 atom, molecules of glucose
Explanation:
The order for the given scenario can be electron, proton, helium atom, carbon 14 atom, and glucose molecule.
What is an atom?An atom is a matter particle that defines a chemical element uniquely. An atom is made up of a central nucleus and one or more negatively charged electrons.
The nucleus is positively charged and contains one or more protons and neutrons, which are relatively heavy particles.
Protons and neutrons are roughly the same mass. However, one proton is approximately 1,835 times heavier than an electron.
A molecule is two or more atoms linked together by chemical bonds that form the smallest unit of a substance that retains its composition and properties.
Chemistry is built on molecules. Molecules are identified by the element symbol and a subscript indicating the number of atoms.
Thus, the electron, proton, helium atom, carbon 14 atom, and glucose molecule will be the correct arrangement.

Describe the effect of an enzyme on the activation energy in a chemical reaction.
Enzymes are biological catalyst meaning they speed up reactions. They do this by lowering the activation energy which results in bond breaking much faster, leading to a quicker chemical reaction.
In conclusion, enzymes speed up a chemical reaction by lowering the activation energy, resulting in a faster rate of reaction as bonds break quicker.

Describe how the amount of light influences the rate of photosynthesis
Without enough light, a plant cannot photosynthesise very quickly - even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply.
When Jeremy returned home after vacation, he noticed that his new plant had not grown. His mother, a florist, told him that it was because the plant was not getting enough sunlight. He moved his plant closer to the window to get more sunlight. How can Jeremy best support the idea that his plant needs more sunlight? A) Ask his mother to make the plant better. B) Wait and see what happens to the plant. C) Remove the plant from direct sunlight after a week. D) Ask his science teacher at school what she thinks could be the reason.
Answer:
Why did you delete my answer? The answer is B.

A new fat-burning pill for men is introduced. To test for effectiveness, 50 men are given the pill and 50 men are given a placebo. After 6 months, the men's body fat percentage is calculated. Identify the control group, the manipulated variable, and the responding variable. Explain how you can identify each.
Answer:
The correct answer is -
The control group - the group of men with a placebo pill,
The manipulated variable - fat burning pill,
The responding variable - men's body fat percentage
Explanation:
The control group of a study is a group that did not get the treatment or manipulated variable so the comparison between the experiment group and the control group can be found and see what are the difference. Here the group of subjects that receives no treatment but a placebo pill only is the control group.
The manipulated variable is the treatment or the manipulation that can cause the response in the subject here the fat burning pills are manipulated variable. The responding variable is the variable known as the dependent variable that is measured to see what effect on the subject occurred here the body fat is the responding variable.
