Answer:

The given muscles can be categorized into following categories:

Smooth muscles: These are involuntary muscles and non-striated muscles which are usually found within the walls of internal organs such as stomach, intestine, uterus et cetera.

Cardiac muscles: These are involuntary and striated muscles which are only associated with the heart.

Skeletal muscles: These are voluntary in nature and striated in structure. They are anchored to the bones with the help of tendons. They help in skeletal movement such as maintaining posture, locomotion et cetera. For example, hand muscles and neck muscles.

Cladograms are graphic representations of the relationship between different taxa according to derivated characters. Option A is correct. Group D has a segmented body and jaws, but no limbs.

<h3>What is a cladogram?</h3>

A Cladogram is a graph drown as a tree, which is based on cladistic analysis. It represents the common ancestral relationships and the emergence of different characters among the involved groups.

The tree-type graph is a ramified diagram that represents the relationship between the involved taxa.

The cladistic analysis follows the maximum parsimony criterium. Explains the character state from the point of view of the fewest changes through history.

Explains evolution with the minimal amount of evolutive changes.

It recognizes the monophyletic groups as natural groups. These groups are the clades, and their classification -sequencing- represents their phylogeny.

The sequencing term refers to lists of groups according to their relation. One group is the brother-group of the following one.

So the cladogram represents the relationship between groups according to a derived character.

The derivated character is any trait that a group passes to its descendants.

Through evolution, the characters change, and new changes are added. When referring to a derivate character, we mean that all the subsequent species in the cladogram carry the trait.

In the provided cladogram, segmentes bodies, jaws, limbs and other traits are derivated characters.

Group D has a segmented body and jaws, but does not express limbs.

This last trait emerged later in history and is expressed by groups E, F and G.

Option A is correct. Group D.

Based on the internal and external solute concentrations, do you think the paramecium will swell up or shrink in this solution?

PtichkaEL [24]

Answer:

Depending on the external and internal solute concentrations, the paramecium will either, shrink, remain the same size or swell.

If the external solute concentration is less than internal solute concentration, the paramecium will swell.

If the external solute concentration is equal to the internal solute concentration, the paramecium will remain the same in size.

If the external solute concentration is greater than the internal solute concentration, the paramecium will shrink.

Note: The concentrations of the external and internal environments were not given.

Explanation:

When two compartments containing solutions are separated by a semipermeable membrane, by means of osmosis, water can move in or out of a compartment depending on the concentration of solutes in either compartments.

In a cell such as a paramecium, the cell membrane serves as a semipermeable membrane.

If the concentration of solutes in both the internal and external environment are the same, there is no net movement of water molecules, and the solutions are said to be isotonic.

If the concentration of solutes in the external environment is greater than the internal environment, water molecules moves out from the internal to external environment, and the paramecium shrinks in size.

If the concentration of solutes in the external environment is less than the internal environment, water molecules moves from the external into the internal environment, and the paramecium swells up in size.
