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.

Answer:

B. Biological Evolution

Explanation:

The biological evolution or evolution is a process by which organisms changes over time and the heritable traits are passed on to the successive generations.

The traits which increase the survival rate or reproductive fitness become permanent in the population when they are passed on to the generations.

In the given question, all the organisms possess DNA, use energy and perform metabolic functions is the result of the transfer of the traits as these characteristic feature allows the cells to survive and thus allows the organism to survive in the different conditions.

Thus, Option-B is the correct answer.

Which label belongs in the area marked X?
jarptica [38.1K]

Answer:

Option A. can reproduce by budding.

Explanation:

Sponges is a multicellular organism which consists of pores that allows water to move through the body. Sponges belongs to kingdom animalia and phylum porifera. Sponges can reproduce by budding. Sponges are placed in kingdom animalia because they are unable to make their own food, made of more than one cell and absence of cell wall.
