Available options are:
A. a scientific inquiry is used only by scientists.
B. scientific inquiry is a process of asking and answering questions.
C. scientific inquiry has only one correct pathway.
D. scientific inquiry often involves similar processes and practices.
E. scientific inquiry involves performing investigations and collecting data.
Answer:
B, D, E
Explanation:
Given that scientific inquiry is a term that described how people mostly scientists, observe the natural world and then come out with credible justification established on the findings that were derived.
Hence, the statements that describe scientific inquiry are:
1. B. scientific inquiry is a process of asking and answering questions. Through this, scientist want to understand the reason behind a certain phenomenon
2. D. scientific inquiry often involves similar processes and practices. To carry out scientific studies, certain steps and practices are required, regardless of the subject under study, which does not entirely change.
3. E. scientific inquiry involves performing investigations and collecting data. This is because to carry out a scientific inquiry, part of the steps and practice includes performing investigations and collecting data, regardless of the subject under study.
Answer:
A glance of earth taken from space will depict it blue. This blue colour is actually water, the major part of the earth is covered with water. We need water for almost everything, for example- drinking, bathing, cooking etc and therefore we should know about the properties of water. 65 % human body is composed of water. Water is essential for the survival of life on earth. Water is distributed unevenly on the earth’s surface. It forms a major solvent and dissolves almost every polar solute. So let us have a look at its properties.
Physical properties of water : Water is a colourless and tasteless liquid. The molecules of water have extensive hydrogen bonds resulting in unusual properties in the condensed form. This also leads to high melting and boiling points. As compared to other liquids, water has a higher specific heat, thermal conductivity, surface tension, dipole moment etc. These properties form the reason for its significance in the biosphere. Water is an excellent solvent and therefore it helps in the transportation of ions and molecules required for metabolism. It has a high latent heat of vaporization which helps in the regulation of body temperature
Chemical properties of water: Amphoteric nature:
Water can act as both acid and base, which means that it is amphoteric in nature.
Example:
Acidic Behaviour: H2O(l)+NH3(aq) ⇌ H3O+(aq)+NH+4(aq)
Basic Behavior: H2O(l)+H2S(aq) ⇌ H3O+(aq)+HS−(aq)
Redox reactions:
Electropositive elements reduce water to hydrogen molecule. Thus water is a great source of hydrogen. Let us see an example in this case:
2H2O(l)+2Na(s)→2NaOH(aq)+H2(g)
During the process of photosynthesis, water is oxidized to O2. As water can be oxidized and reduced, it is very useful in redox reactions.
Hydrolysis reaction
Water has a very strong hydrating tendency due to its dielectric constant. It dissolves many ionic compounds. Some covalent and ionic compounds can be hydrolyzed in water.

Answer:
During telophase nuclear membrane is formed, nucleolus appears and astral rays disappear.
During telophase, the effects of prophase and prometaphase - the nuclear membrane and nucleolus disintegrating are reversed. Two daughter nuclei form in each daughter cell, and phosphatases dephosphorylate the nuclear lamins at the ends of the cell, forming nuclear envelopes around each nucleus.
Since it has no nucleus it's most likely a<u><em> prokaryote</em></u>
Answer:
the 4 different types of bases - adenine, thymine, cytosine, and guanine
adenine always pairs with thymine, and cytosine always pairs with guanine.
(dont know how they pair)
