The correct answer is option C. It causes water molecules to be attracted to other water molecules.
The water is a polar molecule. The polarity of the water is due to the electronegativity of the oxygen. Due to high electronegativity of the oxygen the bond of the hydrogen and oxygen is pulled towards itself, which causes the appearance of slight negative charge on the oxygen and slight positive charge on hydrogen.
Due to this slight charge, the water molecules are attracted towards one another and form hydrogen bonds.
b. question, observe, hypothesize, experiment, analyze, formulate a conclusion
c. question, hypothesize, observe, experiment, analyze, formulate a conclusion
d. observe, question, hypothesize, experiment, analyze, formulate a conclusion
Option D is correct.
The correct order of steps of scientific enquiry are observe, question, hypothesize, experiment, analyze, formulate a conclusion.
Explanation.
Initially we observe something. Like, why a change has occurred. For example, we observed that our room is still dark even after we switched on bulb in our house. It didn't light up as it usually do.
After observing this , we tend to question why it might have happened.
Then we hypothesize i.e. give many reasons for the bulb not working like may be there is no electricity supply, may be switch is impaired or may be bulb has ceased to work.
In order to establish that we are giving the right reason for this, we will prove it through experimenting using a control set and experimental set. Like, if we think that there is a problem in the bulb then we will replace it with the new bulb.
After that we will analyze the results of the experiment. If the room lights up after replacing the bulb then that means there was a problem in the bulb. It also means that there is proper current supply and switch is also working well. But, in case the room still doesn't light up then it simply means that there is a problem with electricity supply or switch. So, we can check for them as well.
In this case if the room lights up then we reach to this conclusion that there was a problem with the bulb otherwise we will that conclude some other factors are responsible for darkness in the room.
Answer;
-Cell theory
The most accepted theory regarding the make-up of living things is the cell theory.
Explanation;
-Cell theory is a theory that includes one or both of the statements that the cell is the fundamental structural and functional unit of living matter and that the organism is composed of autonomous cells with its properties being the sum of those of its cells.
-According to cell theory; All living beings are made up of cells. Cell is the most basic unit of life. All cells must come from pre-existing cells.
-Cells are autonomous, in that they can acquire and use nutrients to obtain energy and they can reproduce. Simple organisms like bacteria are unicellular and composed of a single cell.
a. Mitosis
b. Mutation
c. Apoptosis
d. Angiogenesis
e. Metastasis
that?
Answer:
11 males, 25%
Explanation:
Eleven of the 44 males in this study are taller than 175 centimetres, which makes it one fourth of the total that is 25%. See below:
simplify the fraction
= now multiply it by 100 to convert to a percentage value.
= 25%
Answer:
The correct answer is 10 and this is 50%
Explanation:
Answer: The correct answer for the fill in the blank is Light dependent phase of photosynthesis.
Photosynthesis ( synthesis of food in presence of sunlight) is primarily divided into Light dependent and light independent phase.
Light dependent phase occurs in the thylakoid membrane within chloroplast and the chemical reactions taking place in this phase are also called Hill reaction. Energy from sunlight is absorbed and converted into chemical energy in the form of ATP and NADPH and Oxygen is produced due to splitting of water in this phase.
