Schleiden and schwann believed

Answers

Answer: Plants and animals were made up of same basic structure, which provided support to the cell theory.

Explanation:

Matthias Schleiden stated that plant were composed of cells, and Schwann demonstrated the same fact for animal tissues. In 1839 Schleiden and Schwann formulated the cell theory which states that organisms are composed of cells, which is the smallest unit of life. This means all tissues are made up of cells.

The conclusion is that:

  1. All tissues are made of cells so all living organisms are composed of cells.
  2. A cell is the smallest and basic structural and functional unit of life.
  3. All cells arise from other cells, which already existed before.
Schleiden and Schwann both believed in cell theory. Schwann's theory was that all living things are made of cells. Schleiden believed that different parts of plant organisms are composed of cells.  

What is an independent variable?

Answers

The independent variable is the variable that you change and control in your experiment. The dependent variable is the one you don't have control over and is affected by how the independent variable reacts.

For Example:
Let's say you're doing an experiment seeing how different sugars affect the density of cupcakes. The type of sugar you add would be the independent variable, because you are choosing it. The density would be the dependent variable, since it depends on the sugar used.
It is the variable that you have control over and that doesn't have to depend on another variable. 

According to the Universal Law of Gravitation, every object attracts every other object in the universe. Why can’t you feel the force of attraction between you and Mars?A. There is no force between you and mars.
B. Your mass is too low.
C. Mars is a larger planet than Earth.
D. Mars is a long distance away.

Answers

The correct answer is option D. Mars is a long distance away.

According to the universal law of gravitation, the effect of the force of gravity decreases as the distance increases. The gravitation force is inversely proportional to the radius or the distance. So, the gravitational force exhibited by the Mars is not experienced by us due to the large distance.

The correct response for why you can't feel the force of attraction between you and Mars is because D. Mars is a long distance away, and thus why there is no gravitation attraction between you and Mars.

Which of the options best describes the purpose of photosynthesis?A) Store genetic information to pass onto offspring

B) Convert sunlight into chemical energy to produce a food (sugar)

C) Break down food sources to produce ATP

Answers

Answer:

B

Explanation:

I answered this question before.

Answer:

B

Explanation:

Since plants are autotrophs, they produce their own food, so the purpose of photosynthesis is to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.

Hope this helps:)
