The answer would be:

Question 3 refers to something that can be measured.

If you'd like to know why, please read on:

A scientific question is a question that can lead to a hypothesis.  A question is considered scientific if one can design an investigation to answer the question. To put it simply, you can answer the question through testing and experimentation. These type of questions are based on <u>scientific</u> ideas, thus supernatural, morality, opinions and the like are not considered scientific because they are not observable.

Which characteristic makes osmosis different from diffusion?
nalin [4]

A) Net movement in osmosis is from areas of higher water concentration to areas of lower water concentration. Net movement in diffusion occurs from areas of higher solute concentration to areas of lower solute concentration.

This happens so that both solution have roughly the same concentration

The ____ phylum of seedless vascular plants has about 1000 known living species, including those in the genera
dalvyx [7]

Answer:

D)Lycophyta

Explanation:

The seedless vascular plants or the pteridophyte forms one phylum of the plant kingdom.  The pteridophyte kingdom can be classified into three groups: the Sphenophytes, the pteridophytes and the Lycophytes.

The Lycophyte group contains about 1000 living species as it is the most primitive group of vascular plants. The species is characterised by the presence of the microphyll like the Selaginella and Lycopodium.

The rhizoids of the gametophyte of these plants form the mycorrhizal association with the fungi.

Thus, Option-D is the correct answer.

During respiration, most ATP is formed as a direct result of the net movement of potassium against a concentration gradient pota
Fantom [35]

Answer:

b. False

Explanation:

All living organisms such as plants and animals require energy to function properly (life activities). Thus, the organelle where energy from nutrients is released is generally referred to as mitochondria. Animals retrieve energy using mitochondria to do cellular respiration because they typically act like a digestive system by taking in nutrients, breaking them down and obtaining energy rich molecules for cell-life activities.

Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). These intermediary products are produced at the glycolysis and citric acid cycle stage.

Basically, mitochondria is one of the cell organelles found in all living organisms and it is known as the powerhouse. Therefore, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.

Hence, during respiration, most ATP is formed as a direct result of the net movement of protons down a concentration gradient but not potassium against a concentration gradient potassium.
