Spiders grow from eggs, to spiderlings, to spiders. Insects grow from eggs, to larvae, to insects.

Explanation:

Hope you have a great day :)

In the life cycle of a Spider, there are no larvae, pupae, or nymphs stage.

The first stage, egg

When a female has mated, she stores her spermatophores until she is ready to lay her eggs. The number of eggs is between a few and tens of thousands.

The second stage, egg sacs

The progeny develops in the egg sac, which was designed to shield the eggs from the weather and from predators like birds and ants.

The third stage, spiderlings

The young spiders that resemble their parents the most are called spiderlings.

The fourth stage, adults

The majority of spider species mature in five to ten molts. The spiderlings are prepared to reproduce and restart the life cycle once they reach adulthood.

Answer:  Epithelium tissue refers to the sheets of cells that cover exterior surfaces of the body, lines internal cavities and passageways, and forms certain glands. Connective tissue binds the cells and organs of the body together and functions in the protection, support, and integration of all parts of the body. Muscle tissue is excitable, responding to stimulation and contracting to provide movement, and occurs as three major types: skeletal (voluntary) muscle, smooth muscle, and cardiac muscle in the heart. Nervous tissue is also excitable, allowing the propagation of electrochemical signals in the form of nerve impulses that communicate between different regions of the body

Explanation:

Oxygen gas and water must be present for iron to rust.

A region of the metal’s surface serves as the anode, where oxidation

occurs:

Fe(s) → Fe²⁺ (aq) + 2 e⁻

The electrons given up by iron reduce atmospheric oxygen to water at the cathode, which is another region of the same metal’s surface:

O₂ (g) + 4H⁺ (aq) + 4 e⁻ → 2 H₂O (l)

The overall redox reaction is:

2 Fe(s) + O₂(g) → 4H⁺(aq) + 2Fe²⁺ (aq) + 2 H₂O(l)

The Fe²⁺ ions formed at the anode are further oxidized by oxygen:

4 Fe²⁺ (aq) + O₂(g) 1 (4 + 2x) H₂O (l) → 2 Fe₂O₃ . xH₂O(s) + 8 H⁺(aq)

This hydrated form of iron(III) oxide is known as rust. The amount of water associated with the iron oxide varies, so we represent the formula as 2 Fe₂O₃ . xH₂O.

Simulation

Explanation:

In an experiment where you find something out without being there would be a simulation. Hope this helps :)

Without actually going into space to find out, simulation can be used. Thus option D is correct.

Simulation is the re-enactment of real-world situation for different reason as it cannot be done in real due to several reasons.

This is completely conducted in a controlled environment which also the modification or addition of variable factor if needed.

The primary aim of this technique is to teach people with the appropriate steps to take in the event.

It is mostly used in cardiopulmonary resuscitation (CPR), science  experiments,  movies, sports, and video games.

It is used to identify what type of situation needs to be recreated and assess will be feasible, the goal for doing simulation should be decided, the device, model or parts need to be executed during simulation.

The Mantle

I hope this helps

The mantle is the part which is the most similar to the sun’s convection zone. It is the second layer of Earth.

It is the troposphere that is convective in nature. Troposphere means the region of mixing.

The mantle is  the most similar to sun's convection zone. Sun's convection zone is later  dominated by  the convection currents that carries energy outward to surface. Mantle is second layer of Earth.

The zone is not that  dense enough to  just use the  radiative transfer of  the  energy, infact ,  they uses the  thermal convection zones in just  other words then  it boils. Energy is  then carried out  through the  thermal columns to surface of sun and  later creates  out areas that are seen  as  the solar granulation and  the super granulation.
