Methane (CH4 ) is a covalent compound containing covalent bonds. Carbon atom has atomic number 6. Its electronic configuration is 2,4. It has four electrons in its valence shell and needs 4 more electrons to get the stable noble gas configuration. Hydrogen atom has one electron and needs one more electron to get stable electronic configuration of nearest noble bas, helium. Therefore, one atom of carbon shares its four electrons with four atoms of hydrogen to form four covalent bonds.

The surroundings around us that are interacting with life forms can be called as Environment. We can divide the Environment into two components (Physical and biological) and study it by its measurable characteristics which are called as the environmental factors; they are those which are physical or biological variables and are in one or the other way impacts the existence of life.

 

The environment is a balanced Energy flow pattern through the interdependence of various Components & their interaction and transformations; generally termed as Ecosystems.

The environment is divided into biotic and abiotic components

Biotic Components are Autotrophs(Producers) which includes Microbes, Phytoplankton: These harnesses the energy of inorganic substances by Photosynthesis or Chemosynthesis to convert into organic substances (Life Building Blocks)

Under autotrophs, it is further divided into Heterotrophs and decomposers

Primary Heterotrophs are Zooplankton, Small Fish, Prawns, Crabs, feeds on Autotrophs

Secondary Heterotrophs are Large Fishes, Seagulls, Sea Snakes, Turtles o Tertiary Heterotrophs: Sharks, Marine Mammals, Sea Eagles, Humans: consume other organisms for energy

Decomposers are Detritus bacteria: destroy debris, such as decaying leaves or dead animals; keep streams clean and clear by filtering and recycling nutrients

Abiotic Components are factors like Temperature, Precipitation, Geology, Soil, Sunlight, Water chemistry (minerals and salts).

“Muscular” force is not a specific term. It is assumed that the question is meant as strength which is usually measured by the amount of weight a person can do in an aspecific exercise.

Force, as one would know, is defined as Mass x Acceleration, so in a physics sense, someone who moves 200 pounds faster than someone who is moving 250 pounds could potential be exerting more “force”.

In other words, the movement the only way we move is via muscles, examples would be the bicep curl your heartbeat, and your fingers are moving to type this question if you want to know which muscles let you do what, keep in mind that a muscle can only contract or shrink. They are all attached to your bones when they contract they pull your bones, and that’s how you move so think about where the muscle would have to be to move that bone by contracting.

 I hope this helps.

The unwanted plants that grow in-between crops are called weeds. The process of removal of such unwanted plants is called weeding. It has to be done 2-3 times in a week, and usually practised during the earlier stages of crop cultivation. The advantages of weeding are:

 

  •  The weeds compete with the actual crop for space, nutrients and water. Hence, the removal of these unwanted plants provides an ample amount of nutrients and water to the crops. 
  • It increases the fertility of the soil.
  • A weeded crop will aid in better penetration of the sun and the wind beneath the soil and also reduces the humidity. 
  • Due to better penetration of the wind and the sun, it reduces the number of diseases caused by crops and also helps in controlling pests. 
  • It loosens the soil, which helps in the penetration of water to the roots of the cultivated plant.

 

Despite the advantages of weeding, it is advised to keep a few spots of these unwanted plants between the crops. This ill act as a refuge and will help in conserving the ecosystem. 

The growth of weed can be controlled or stopped by using chemicals like herbicides, mulch or can also be controlled mechanically.

River valleys are most fertile region and the first human settlement were all done to do agriculture. The fertile soil in these regions were best suited for agriculture. Hence people first settled near river valleys.

Mitochondria is known as the powerhouse for the cell. They are responsible for cellular respiration as in the energy is released in the form of ATP, i.e., Adenosine triphosphate.

 

While the cells release 2 ATP, mitochondria release 34 ATP which adds up to 36 ATP. Since mitochondria release a significant portion of the ATP, they are called the powerhouse of the cell.

Through the process of cellular respiration, (commonly known as aerobic (with oxygen) respiration but it also includes glycolysis- a way of making energy without the presence of Oxygen) Mitochondria produce a molecule called ATP or Adenosine TriPhosphate.

The mitochondria are referred to as a "powerhouse" because it's the only cell organelle that can make energy in a form the cell can use to run various cell activities (1 example is active Transport, the movement of substances across a membrane against its concentration gradient)

So this is why Mitochondria is called the powerhouse of the cell.
