Hypothesis is a proposed explanation which is made on the basis of given experimental data taken as starting point for further investigation. All hypothesis test are conducted in a same manner fiollowing the four main steps:
1. State the hypothesis
2. Formulate an analysis plan
3. Analyzing the data obtained
4. Final step is to analyze the results
There are three types of variables taken in an experiment:
1. Independent variable: light, temperature, humidity
2. Dependent Variable: these depends upon the other variable. changes in the independent variable may cause the dependent variable to change, for example, growth of plant is a dependent variable which depends upon the amount of light(independent variable), the plant receives
3. Controlled Variable: these variable can be controlled and prevented from being change like ty[pe of plant, type of soil
Answer:
Firstly they are too big to pass through the natural pores of the cell membrane the way water molecules do through aquaporins. Secondly, they would not pass through the hydrophobic layer of the cell membrane because the sodium ions are charged. This is because the hydrophobic layer does not interact positively with charged molecules/ions. Additionally, because sodium ions would be traveling up the concentration gradient into the cell, there is need for active transport. The channels proteins are able to harness energy from ATP to actively transport the sodium ions into the cell.
Answer
Vagus Nerve
Explanation:
That would be the vagus nerve.
Well I want to first point out sugars molecules DO NOT form amino acids. In addition, a sugar by definition is a 6 carbon ring. All molecules form bonds primarily based the valance electrons of each atom or molecule, and to a lesser degree electronegativity. Valance electrons refer to the number of electrons in the outer shell of a neutral atom. All atoms want to have 8 electrons around them, this is referred to as the octet rule. Therefore the total number of bonds an atom can for is 8-the # valance electrons. For example Oxygen has 6 valance electrons and can form 2bonds. This is the basics. Atoms are able to move and share electrons to form more bonds, or double and triple bonds.
