Answer:

Unlike the other planets of the solar system, Uranus is tilted so far that it essentially orbits the sun on its side, with the axis of its spin nearly pointing at the star. This unusual orientation might be due to a collision with a planet-size body, or several small bodies, soon after it was formed.

Explanation:

the axis is vertical

Answer:

The axis is pointing towards the sun!!!

Answer:

The correct answer is X.

Explanation:

Lysosomes are heterogeneous structures present in animal cells which are bound by single membranes. They are of varying shape and size and contains hydrolytic enzymes inside it.

Lysosomal membrane has H⁺ ATPase which pumps H⁺ into the membrane through ATP hydrolysis. This pumping of H⁺ makes the internal pH of lysosome acidic.

Lysosome contains many hydrolytic enzymes like protease, lipase, nuclease, therefore, lysosome protects the cell from pathogens by engulfing it and hydrolyze it by its hydrolytic enzymes.

The process by which substance comes from outside cell and broken down through lysosome is called heterophagy.

Electrical energy is caused by moving particles that have a negative or positive charge. These charged particles are called electrons. The faster the electrons are moving, the more electrical energy they carry. Electrical energy commonly moves through a wire in an electrical circuit.

                                     [tex]\huge\boxed{Electrons.}[/tex]

Electrons are particles that move to create electricity. In other words, they are responsible for electric currents. Thus, the answer should be Electrons.

Answer:

10.01461 kilojoules of thermal energy are absorbed when 98.5 g of water is heated from 24.5 ° C to 48.8 ° C

Explanation:

Sensible heat is the amount of heat that a body absorbs or releases without any changes in its physical state (phase change) causing a change in temperature.

The equation that allows to calculate heat exchanges in this case is:

Q = c * m * ΔT

where Q is the heat exchanged by a body of mass m, constituted by a substance of specific heat c and where ΔT is the change in temperature.

In this case:

Replacing:

Q= 4.184 [tex]\frac{J}{g*C}[/tex] *98.5 g* 24.3 °C

Solving:

Q=10,014.61 J

Since 1 J is equal to 0.001 kJ, then you can apply the following rule of three: if 1 J is equal to 0.001 kJ, then 10,014.61 J is equal to how many kJ?

[tex]kJ=\frac{10,014.71 J*0.001 kJ}{1 J}[/tex]

kJ=10.01461 kJ

10.01461 kilojoules of thermal energy are absorbed when 98.5 g of water is heated from 24.5 ° C to 48.8 ° C

Students can address water and air pollution by organizing seminars to raise awareness and educate others about the issues,

A. Organize seminars

B. recycling and waste disposal

Water pollution and air pollution are significant environmental hazards that require collective efforts to address. Students can play a crucial role in raising awareness and taking action to mitigate these issues. Here are the appropriate answers from the given options:

What can students do to address these environmental hazards?

A. Organize seminars

B. recycling and waste disposal

A. Organize seminars: Students can organize seminars or workshops to educate other students and the community about the deteriorating environmental conditions and the steps needed to improve the area. By sharing knowledge and information, students can raise awareness about the causes and impacts of water and air pollution, as well as the potential solutions to mitigate them. Seminars can provide a platform for experts, scientists, and environmentalists to share their expertise and inspire action.

B. Recycling and waste disposal: Encouraging other students to volunteer for workshops about recycling and waste disposal is an effective step toward addressing environmental hazards. By promoting proper waste management practices, such as recycling, composting, and reducing single-use plastics, students can contribute to minimizing pollution and conserving resources. These workshops can educate students on the importance of responsible waste disposal and provide practical tips and techniques to implement in their daily lives.

In summary, students can address water and air pollution by organizing seminars to raise awareness and educate others about the issues, as well as by promoting recycling and proper waste disposal practices. Through these actions, students can foster a culture of environmental stewardship and inspire positive change in their communities.

Answer: solid particles deposit at the base of the vessel because they are heavy compared to the liquid particles.

Explanation:

Answer:

Explanation:

All chemical reactions involve energy. Energy is used to break bonds in reactants, and energy is released when new bonds form in products. Endothermic reactions absorb energy, and exothermic reactions release energy. The law of conservation of energy states that matter cannot be created or destroyed.

The chemical reaction absorbs energy by comparing the energy received when bonds in the reactants are broken with the energy released when bonds in the products are formed. Exothermic is refers to chemical reactions that release the energy.

The term chemical reaction is defined as a process that leads to the chemical transformation of one set of chemical substances to another.

If heat is absorbed during the reaction,then the change in enthalpy is positive and if heat is released, then the change in enthalpy is negative.

All chemical reactions contain energy. But, not all chemical reactions release energy. In some chemical reactions, the energy is absorbed rather than released.

Thus, The chemical reaction absorbs energy by comparing the energy received when bonds in the reactants are broken with the energy released when bonds in the products are formed.

Answer:

C. Period

Explanation:

The elements from this section of the periodic table belongs to the same period.

A period on the periodic table is a horizontal arrangement of elements according to their atomic number.

Answer:

4.5 moles of H2O.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

C2H5OH + 3O2 —> 2CO2 + 3H2O

From the balanced equation above,

1 moles of C2H5OH reacted to produce 3 moles of H2O.

Finally, we shall determine the number of mole of H2O produced by the reaction of 1.5 moles of C2H5OH. This can be obtained as follow:

From the balanced equation above,

1 moles of C2H5OH reacted to produce 3 moles of H2O.

Therefore, 1.5 moles of C2H5OH will react to produce = 1.5 × 3/ 1 = 4.5 moles of H2O.

Thus, 4.5 moles of H2O will be produced.

Explanation:

calcium has lost 2 electrons.

Answer:

Electric Current

This is a flow of electrons (such as the flow of electrons in a wire to light up a lamp).

Insulator

These stop the electricity from flowing (think rubber and glass).

Resistance

This is slowing the flow of electrons (the current) and where some of the electrons' energy gets converted into heat.

Conductor

These allow electricity to flow easily through them (think copper and aluminum).

Answer:

6.533 × 10^-21J

Explanation:

The energy of the microwave photon can be calculated using:

E = hf

Where;

E = energy of photon (J)

h = Planck's constant (6.626 × 10^-34 J/s)

f = frequency (9.86 x 10^12 Hz)

Hence, E = hf

E = 6.626 × 10^-34 × 9.86 x 10^12

E = 65.33 × 10^(-34 + 12)

E = 65.33 × 10^(-22)

E = 6.533 × 10^-21J

The energy of the microwave photon is
