A diploid number of chromosome is reduced to a haploid number

Biology
1 answer:
guajiro [1.7K]3 years ago
7 0

Explanation:

In addition, in meiosis I, the chromosomal number is reduced from diploid (2n) to haploid (n) during this process. ... In humans (2n = 46), who have 23 pairs of chromosomes, the number of chromosomes is reduced by half at the end of meiosis I (n = 23).

Any stimulus that opens a ________ ion channel will produce a graded potential.
Fiesta28 [93]

E) All of the answers are correct.

Ion channels are proteins located in the membrane that allow ions to pass through the channel pore. Ion channels can be classified (by what opens and closes the channels) into few groups:

• Voltage-gated channels-open and close in response to membrane potential

Examples: Voltage-gated proton channels, Voltage-gated sodium channels, Voltage-gated potassium channels

• Ligand-gated (neurotransmitter) or ionotropic receptors (ligand binds to extracellular domain of the receptor

Examples: "nicotinic" Acetylcholine receptor, ionotropic glutamate-gated receptors

• Lipid-gated- lipid molecules bind to the  transmembrane domain of the channel

Example: Inward-rectifier potassium channels

• Light-gated channels-like rhodopsin channel that is directly opened by photons

• Mechanosensitive (e.g. stretch, pressure) ion channels.

horrorfan [7]

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.
