Answer:

The five spheres of Earth are the geosphere, hydrosphere, atmosphere, cryosphere, biospheres.

The ocean is one environment that is comprised of both the hydrosphere and biosphere. The ocean, being nothing but water, serves as the whole known world to all marine life within, which serves as the biosphere component.

Mountainous environments are also made up of multiple spheres; including, but not limited to, cryosphere, geosphere, with a little bit of biosphere as well. Mountains--which are giant rock formations created by years of seismic activity--are mostly covered in snow near the peaks due to low temperature, which will melt at different points during the year. A small assortment of wildlife call these areas home, such as jackrabbits, white-tailed deer, mountain goat, bear, gray wolf, coyote, lynx, and wolverine.

I am Lyosha [343]

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.

______ is a defense mechanism that occurs when group members believe the logical, but false explanation of their behavior.

Ede4ka [16]

Answer:

The correct answer is- Rationalization

Explanation:

Rationalization is a defense mechanism that involves the action to justify their unobvious behaviors by logical reasons to avoid true explanation. For example, if an employee is not given promotion might rationalize his disappointment by saying that he does not want extra responsibilities.

Rationalization may help the person to avoid guilt and maintain self-respect when he has done something wrong. Many times rationalization is not harmful to the person but if it becomes a habit of a person it can cause a problem for him and others. Therefore the correct answer is rationalization.
