<h2>Upper limb,Pectorial girdle and Axial skeleton</h2>

Explanation:

Upper limb-

  • The muscles of the upper appendage can be divided  into 6 distinct areas such as <em>pectoral, shoulder, upper arm, front lower arm</em>, <em>back lower arm, and the hand</em>
  • There are 4 muscles of the pectoral locale <em>pectoralis major, pectoralis minor, serratus foremost and subclavius  </em>

Pectorial girdle-

  • The <em>shoulder </em>girdle <em>or pectoral </em>girdle is the arrangement of bones in the attached skeleton which interfaces with the arm on each side
  • In many of the it comprises of the <em>scapula and clavicle</em>
  • In many <em>species  have three bone found in the shoulder, it connected of the coracoid and clavicle   and scapula</em>

Axial skeleton function-

  • The pivotal skeleton underpins and ensures the <em>mind, spinal rope and huge numbers of the interior organs</em>
  • It likewise gives locales to the connection of different bones and muscles in the body and shields the nerves and veins from the <em>cerebrum and spinal line.</em>

Is the movement of water along the concentration gradient
Nuetrik [128]

Answer:

<em>- Is the movement of water along the concentration gradient: </em><em>Osmosis</em><em>. </em>

<em>- Is the use of energy to move the particles against the concentration gradient: </em><em>Active transport</em><em>. </em>

<em>- Is the movement of particles by diffusion without energy: </em><em>Simple diffusion</em><em>. </em>

<em>- Is the movement of particles along the concentration gradient: </em><em>Passive transport</em><em>.</em>

Explanation:

The mechanisms of cellular transport involve all the processes that the cell carries out to incorporate substances into its interior or send them to the extracellular space, through its semipermeable cell membrane.

<h3>- Osmosis</h3>

Is a type of transport that consists of the passage of water from a space with a lower concentration of solutes to one with a higher concentration, in order to reach equilibrium, following a concentration gradient.

The concentration gradient is given by the difference in concentration between two substances, which indicates the direction in which molecules, such as water, should move from one place to another.

<h3>- Active transport</h3>

Unlike passive transport mechanisms, which depend on a concentration gradient that determines the movement of particles, in active transport there are two characteristics that define it:

The passage of substances into the cell against a concentration gradient.

The use of energy to carry out this process.

In this case, the passage of substances through the cell membrane will be according to the requirements of the cell, or when they cannot pass through the membrane.

<h3>- Simple diffusion</h3>

According to the characteristics of the cell membrane, some substances can pass freely through it while others require special mechanisms. When a molecule is able to pass through the membrane without the use of special mechanisms or energy we speak of simple diffusion.

In a cell membrane, whose composition is by hydrophobic or non-polar lipid molecules, simple diffusion allows the passage of non-polar molecules, gases and alcohol.

<h3>- Passive transport</h3>

Refers to the mechanism of entry and exit of substances from the cell that does not require the use of energy.

The mechanisms involved in the passive transport of the cell are simple diffusion, osmosis, facilitated diffusion - which requires special conveyors or channels - and ultrafiltration, which depends on hydrostatic pressure. Examples of substances using this mechanism are lipid molecules, water and electrolytes.
