Muscle is composed of small units known as myofibril which itself composed of cylindrical bundles of thread like filaments; thick filament and thin filament known as myosin and actin respectively.

These filaments make up a myofibril which is organized into a chain of contractile units called sarcomeres. . There are two more proteins known as titin and nebulin which also contribute to the structure of sarcomere.

The function of the muscle is to contract and these filaments play a major role in it

Naturally occurring solid mixture of one or more minerals and organic matter
alina1380 [7]

The naturally occurring solid mixture of one or more minerals and organic matter is known as a Rock.

A rock is a naturally occurring substances that is a solid mixture of one or more minerals together with organic matter.

<h2>Further Explanation;</h2>
  • Rocks are classified based on the chemical composition, texture and the way they are formed.  One type of rock may change from one form to another through a rock cycle.
  • Rock cycle is the process through each various rocks change from one form to another, normally an interchange between the three major types of rocks.

There are three major classification of rocks:

<h3>Sedimentary rocks </h3>
  • Sedimentary rocks are types of rocks that are formed through accumulation of sediments at low temperatures in tectonic layers and sinks. These sediments includes; pebbles, shells, sand and other material fragments.  
  • The sediments accumulates in layers and then harden into rocks over a period of time.
  • Examples of sedimentary rocks include; limestone and conglomerate
<h3>Metamorphic rocks</h3>
  • These are types of rocks that are formed as a result of changes that occurs due to intense heat and pressure under the surface of the earth. They result from action of heat and pressure on other rocks that pre-existed.
  • These types of rocks are characterized by shiny crystals, ribbon-like layers among other features.
  • Examples of metamorphic rocks are marble and gneiss

<h3>Igneous rocks </h3>
  • These are types of rocks that are formed as a result hardening and cooling of magma from volcanic eruptions. Magma may cool inside the earth or when on the surface of the earth as a result of volcanic eruptions. The lava from this eruptions cools and hardens to form metamorphic rocks.
  • Igneous rocks are glass-like and shiny with no crystals. They may also have tiny spaces and holes due to gas bubbles trapped during the cooling process.
  • Examples of igneous rocks include obsidian and basalt.
  • The three types of rocks may be further classified in terms of chemical composition, texture and formation.

Key words: Rocks, types of rocks, chemical composition

What does the biodiversity on Earth indicate about its organisms?
mixas84 [53]

A high biodiversity tally may indicate that some of its organisms may be able to survive drastic environmental changes. If there weren't at least a few organisms that contribute to biodiversity, most of the biotic Earth would be gone by now.

For example, woolly mammoths were unable to adapt to the up-and-coming warmth of the poles. Because they lacked biodiversity among their species, all of them died out and weren't able to adapt to the heat.

A elephant cell has 20 chromosomes. how many chromosomes will the cell have just before mitosis begins in the elephant cell?
lora16 [44]

The elephant cell will have 20 chromosomes.

Cells undergo interphase before getting to the mitotic phase. At the S phase of the interphase, the amount of DNA in the cell is double by replication. However, the number of chromosomes remains intact.

Thus, the cell gets to the mitotic phase with the same number of chromosomes that is usually present in normal vegetative cells of the animal.

Why are formation and decay considered a cycle of nature?
harkovskaia [24]
They are considered so because are the indispensable parts of the nature cycle.Without formation,decay cannot be possible and similarly,formation cannot be possible without decay.In addition to this,THEY ARE IN A CHRONOLOGICAL MANNER SET BY NATURE and that's why cannot be seperated and so together constitute the cycle of nature.
