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.

<u>Group D</u> 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.

Imagine a population of moths. White moths are easier for birds to see and eat. Black moths blend into their surroundings, so th

Ksju [112]

Answer:

The correct answer is - natural selection.

Explanation:

Natural selection is a process of adapting according to the environmental change in order to survive and reproduce and increase their number. It is represented by Darwin for the first time. Natural selection leads to evolution.

In this case, White moths adapt according to the environment by increasing the population of black moths in order to blend with the surrounding and as the result, black moths are more likely to produce and survive and passed this trait to the next generation.

Which events take place in the light-dependent reactions of photosynthesis?

borishaifa [10]

The correct answer is : Light energy is captured by plants; light energy is converted to chemical energy.

In the process of photosynthesis, special pigment molecule called chlorophyll can capture the energy of the light, more specifically the photon. When a particle of light (a photon) with a specific energy reaches this pigment in the leaves of plants, the energy is transferred from the particle to the molecule, and the molecule becomes excited. This is the phase where the energy of the light is captured and transformed into chemical energy that can later be used to make sugars.

All of the later chemical processes that transfer the energy from the excited chlorophyll to the sugar molecules are not dependent on the light and can happen during the night as well.

iris [78.8K]

<h2>Answer :</h2><h3>Part 1:</h3>

Yes, embryos have leaves which are known as cotyledons.

Plants with two embryonic leaves are termed dicotyledonous ("dicots") .

Plants with one leave are known as monocotyledon.

Six (6) Chromosomes.

As embryo is formed from the combination of egg and sperm. If embryo has 12 chromosomes then sperm will have half means 6 chromosomes.

After a dye diffuses uniformly throughout a glass of water, the dye molecules are no longer moving. True or false?

Anton [14]

The answer is false, liquid molecules continue to move even after the concentration is uniform.

Diffusion happens because there’s a concentration gradient between the dye and the water, therefore dye molecules moves to the water area. But note that this is only the net movement of the molecules, which means, even if more molecules are moving towards water, there are still some dye molecules that are moving in the opposite direction.

So, after the concentration is equal, the motion of the dye molecules does not stop, they still move in random directions, but there’s no net movement instead, as there’s no concentration gradient. Remember molecules are always moving in all directions , it just depends on whether there’s a net movement or not. If there’s no net movement, the amount of molecules moving to each and every direction is always equal.
