Answer:

Energy pyramids is representation of food chain where producers lie at the base of pyramid followed by primary, secondary and tertiary consumer. A tertiary consumer lies at the top of the energy pyramid .

Explanation:

An ecological pyramid is a chronological arrangement of organism in which the organism producing the food lies at the base of pyramid and remaining all organism lie above it.

Each level of an ecological pyramid is called a trophic level and an organism lying at any trophic level feed upon organism lying in trophic level prior to it.

Energy transferred to an organism lying at certain trophic level is 10% of the energy contained in an organism lying at its lower trophic level. remaining 90% of the energy is used by an organism for its internal metabolic process.

irga5000 [103]

In prophase 1:
Chromosomes become visible, crossing-over occurs, the nucleolus disappears, the meiotic spindle forms, and the nuclear envelope disappears.
In metaphase 1:
The pairs of chromosomes (bivalents) become arranged on the metaphase plate and are attached to the now fully formed meiotic spindle. The centrioles are at opposite poles of the cell.

This type of membrane transport moves substances against the concentration gradient from an area of low concentration to an area

sashaice [31]

Answer:- Active transport

Explanation:-

There are two types of membrane transports

1. Passive transport - this type of transport occurs without the input of any energy and the molecules move along the concentration gradients that is from high concetration to low concentration.

2. Active transport- this type of transport takes place to move the molecules against the concentration gradient that is from low concentration to high concentration.

The active transport is of two types:

1. Primary active transport- in this type of transport ATP is used as an energy source to move the substances against the concentration gradient.

2.Secondary active transport - in this type of transport the gradient formed by the active transport is utilized and it involves the movement of 2 substances at a time aross the membrane. That is the movement of one molecule is coupled to another.

The membrane proteins that are associated with active transport are called as carrier proteins. These proteins have a binding site for the molecules that they transport. Once they bind to the specific molecules, a conformation change is induced and this leads to the transport of the molecule across the membrane.

So, the active transport is basically responsible for utilizing the energy from ATP and carrier proteins to move the substances across the membrane against their concentration gradient i.e. from low concentration to high concentration.

Allushta [10]

Answer:

The solute is powdered drink mix

Explanation:

The solute is powdered drink mix is solute because solute is any substance that dissolves in a solvent while solvent is the substance that dissolve solute or the dissolving medium. When solute dissolve in solvent it is called solution.

Solution is an homogeneous mixture of substance which comprises of solute that dissolve in solvent.
