What is parasitism? Give two examples in which the host is harmed.

Artist 52 [7]

<h2>GIVE ME BRAINLIEST.</h2>

Parasitism is defined as a relationship between two species in which one organism (parasite) lives on or within the other organism (host), causing the host some degree of harm. A parasite reduces its host's fitness but increases its own fitness, usually by gaining food and shelter.

True or false: In a healthy individual at rest, the maximum amount of oxygen that can diffuse into the pulmonary capillaries wil

MrRissso [65]

Answer:

Cellular respiration is a complex biochemical process, whose main objective is to achieve that with the use of nutrient elements and in the presence of oxygen, energy, CO2, H2O and hydrogenation are produced as a final result. For vital reasons, since for the cell it can live and function, it needs energy, it is that the cells need the process of cellular respiration. In unicellular organisms, the process is simpler, since the cell membrane is in contact with the source of oxygen, either a liquid medium or an air medium.

In multicellular organisms, the process becomes more complex and much more dependent on multiple factors, because several mechanisms or events are needed, which guarantee oxygen and nutrients reach the different cells, degree of the degree of specialization that they have developed and from the place where they meet.

erik [133]

<span>Forced expiratory volume is the percentage of the vital capacity that can be expelled in a specific period of time. This value is obtained by inspiring as much air as possible and then expelling the air from the lungs as quickly as possible. Individuals with decreased ability to expire typically exhibit decreased FEV values. Maximum voluntary ventilation is the greatest amount of air that can be taken into, and then expelled from, the lungs</span>

Which of the following phylogenetic trees best represents this data?

Bess [88]

Phylogenetic trees are tree-like graphic representation that show the evolutive relationship between different taxa.

<h3>What is a phylogenetic tree?</h3>

A phylogenetic tree is a graphic representation of the evolutive relationship between different taxa.

This representation has a tree-like shape.

The phylogenetic tree expresses how far or close are in evolutive history the different groups.

<h3>Structure of the phylogenetic tree</h3>

The phylogenetic tree is composed of,

Lineages → The taxonomic groups of interest. These are placed in the extremes of the branches.

Nodes → These are the ramification points, which are also known as divergence points. They represent the location of the most recent common ancestor.

Root → This is the oldest common ancestor that all lineages share. The first one in the tree.

⇒ Highly related groups that share a recent common ancestor. This means that they all diverge from the same node.

⇒ Lineages less related to each other are those whose common ancestor is far away in history.

In a phylogenetic tree, the most distant group receives the name of outgroup.

It shares no traits or characters with the lineages of interest that compose the ingroup.

You can compare the outgroup with the ingroup to determine the evolutive relationship and which characters are primitive or derived.

Since I do not have further information, I will describe each of the trees.

A) Capibara and camel share a more recent common ancestor in history than they do with guinea pig. Capibara y camel are more closely related.

B) Guinea pig and Capibara share a more recent common ancestor in history than they do with camel. Capibara y guinea pig are more closely related.

C) The three lineages have the same common ancestor and are equally related to each other.

D) Guinea pig and Camel share a more recent common ancestor in history than they do with capibara. Camel y guinea pig are more closely related.

According to your information, you can determine which tree is the best.
