Answer:
Option (4)
Explanation:
The earth is comprised of numerous lithospheric plates. This lithosphere is comprised of dozens of major plates and a few minor plates. These plates are constantly in motion over the less dense asthenosphere layer where the rocks tend to flow during deformation. This plate motion takes place due to the creation of convection current in the mantle region as a result of which the plates move under the influence of uprising magma. These currents are formed because of the heat supplied from the core of the earth.
Some of the major plates are Indo-Australian plate, North American Plate, South American plate and the Pacific plate.
Some of the minor plates include the Cocos plate, Nazca plate, and Caribbean plate.
Thus, the correct answer is option (4).
Answer:
Arrangement of the actin and Myosin filament
Explanation:
SACROMERE :An elastic membrane which serves for the *arrangement of the actin and myosin filament *
The fasciculi consist of still smaller bundles of elongated, cylindrical muscle cells, the fibre. Each fibre is a syncytium, i. e, has many nuclei. With the aid of an electron microscope, it can be seen that the muscle fibre is made up of smaller units, the myofibrils. Each myofibrils consists of small protein filaments known as *ACTIN and MYOSIN* filaments. The myosin filaments are slightly thicker and make up the darkband(or A-band). The actin filaments make up the light bands(I-band) which are situated on either side of the dark band. The actin filaments are attached to the Z-line.
During the contractions of skeletal muscle, the actin filaments slide inwards between the myosin filaments. Mitochondria provides the energy for this to take place. This action causes the shortening of the sacromeres(Z-lines move closer together, which in turn causes the whole muscle fibre to contract.This can bring shortening of the entire muscle such as biceps, depending on the number of muscle fibres that were stipulated. The contraction of the skeletal muscle is very quick and forceful.
Hiya once again,
The fluid mosaic model explains only but observations about the structure of functioning cell membranes. However, a lipid bilayer is used to describe the membranes of animals and plant cells. This isn't a great question to be honest with you, so let's try it like this:
Triglyceride: Ester formed by Glycerol and 3 fatty acid groups. These guys are basically made up of fats and oils. (Ex- High concentrated blood)
Phospholipid: A lipid containing a phosphate (an ester of phosphoric acid) in its molecule.
Bilayer: A film (layer) of molecules (created by lipids) that are arranged with it's hydrophobic (meaning whatever it is does NOT mix well with water... Kinda like pouring sugar into a cold glass of water and waiting for the sugar to melt) inverted at both ends of the film.
Embedded Proteins ('Intrinsic Proteins' if you wanna be fancy): Having one or more segments embedded into the phospholipid bilayer.
Stationary (phase): This is something that is mostly involved with bacterial growth
I really hope this helps! Let me know what you got and which one was right!
<span>The most significant characteristic of sexual reproduction is the fact that the offspring's traits/ characteristics are not identical to the parents' traits. So, there is a variety of looks and traits passed down.
Hope this helped you!

Answer:
You will have to find many different methods in which the resource is most useful. Some resources may be useful in one place and some may be useful in another its all about how you use the resource.
