Can you list some examples for each of the three domains of bacteria, archaea, and eukarya?
Answer: bacteria: e Coli
Explanation:
The bacteria and archaea are microorganisms. Escheria coli, staphylococcus aureus etc are examples of bacteria. Different types of archaea includes bathyarchaeota, thermoproteota etc. Eukaryotes are multicellular organisms such as plants, fungi, animals etc.
What are eukaryotes?Eukaryotes are multicellular organisms with developed cellular organization and developed nucleus. All the higher level organisms such as humans, animals, fungi, plants etc are eukaryotes.
Microorganisms such bacteria are single celled organisms and they are called unicellular having only one cell without a developed nucleus.There are many types of bacteria based on their structure and functions such as spirulina, staphylococcus, vibrio coli etc.
Archaea is another type of unicellular organism which first classified as type of bacteria, but later they are included in a new class of domain. They are natural methanogens that is they produce methane gas. Some examples are bathyarchaeota, thermoproteota etc.

Explanation:
Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.
Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.
[tex]Al(s)\rightarrow Al^{3+}(aq)+3e^-[/tex]
Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

It is critical in the process of cellular respiration.
It has a huge electronegativity difference between its atoms.
It allows sunlight to pass through it.
Answer:
It's critical in the process of cellular respiration
It is critical in the process of cellular respiration; is the correct answer; as water plays a very important role in transportation of oxygen and maintaining cell structure.
What is cellular Respiration ?The process by which organisms combine food molecules with oxygen to form energy , which is used for life sustaining activities is called Cellular Respiration.
Carbon Di-Oxide and Water are produced as by products.
Water acts as a solvent in facilitating the transport of oxygen in respiration.
At the molecular level, water permits everything inside the cell to have the proper structure which is very important for biological processes.
Hence option B , i.e. It is critical in the process of cellular respiration; is the correct answer.

1. Caffeine has a distribution coefficient of 8.4 for methylene chloride (CH2Cl2)/water (H2O). How much caffeine will be extracted from a 60 mL cup of Turkish coffee (100 mg caffeine) by 40 mL of methylene chloride (CH2Cl2)
Answer:
91.224 mg of caffeine will be extracted from a 60 mL cup of Turkish coffee (100 mg caffeine) by 40 mL of methylene chloride (CH2Cl2)
Explanation:
The distribution co-efficient of Caffeine for methylene chloride (CH2Cl2)/water (H2O) is 8.4
Volume of Turkish coffee = 60 mL
Volume of methylene chloride (CH2Cl2) = 40 ml
Distribution coefficient is represented by K
[tex]8.4 = \frac{\frac{X}{60}}{\frac{100-X}{50} } \\X = 91.224[/tex] mg

Consider this statement: Earth is the only source of gravity in the solar system. Do you agree? Give
your reasons.
Answer:
Explanation:
You're kidding, right?
Earth is a puny little planet stuck in the Milky Way which is not a particularly large galaxy that has millions of stars with many times more our gravitational influence.
We are very lucky that the gravitational force is so weak. Were it not, We would be pulled in every direction imaginable and swallowed many times by larger and larger black holes until our existence could never be traced.
We would be like 1 electron in all the atoms of the Universe combined. There's no end to the size and scope of the forces involved if the gravitational force were even a small bit larger than what it is now.

An alpha particle is an ionized helium nucleus, consisting of 2 protons and 2 neutrons bound together. When alpha particles are beamed toward a thin metal foil, most of them pass through, undergoing a small deflection, while a small fraction of them bounce back at much larger angles in excess of 90 degrees relative to their incoming direction. The reason this happens is that Group of answer choices
Answer:
Due presence of empty as well as heavy particles.
Explanation:
The main reason for this is the presence of empty spaces as well as heavy particles in the nucleus of Helium atom. Most of the beam pass through the helium atom due to the presence of empty spaces in the atom whereas some beams deflect from the helium atom because both repel each other due to same charge i.e. positive charge. Few beams of light bounce back with an angle of 90 degree due hitting with the nucleus where heavy particles such as neutron and proton are present.
