What internal structure is a functional part of an open circulatory system, which is found in arthropods and mollusks?
kupik [55]

Answer: Haemocoels

Explanation:

In the open circulatory system found in arthropods and mollusks, the heart pumps blood into a blood vessel which branches and opens in an internal structure called Haemocoels.

The haemocoel is a highly functional part because it allows

- organs and tissues to be bathed in blood,

- for exchange of materials to occur between the body cells and the blood.

- blood to eventually flows back to the heart.

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.

Kaden is making waves using a string tied to a doorknob. He moves the string up and down and creates four waves, as shown in the
Alexeev081 [22]

Answer:

C

Explanation:

For standing waves, the areas where the amplitude is zero are referred to as nodes while the areas where the amplitude is at the maximum are known as antinodes.

A standing wave derives its feature primarily from the fact that there are certain points along the medium of transmission that are apparently seeing to be standing still with no displacement whatsoever. At the same time, there exist opposing points to the points of zero displacements. These points have a maximum displacement in both the positive and negative directions. While the former is referred to as nodal points, the latter is known as the antinodal points.

Which describes the correct pairing of DNA bases?
liberstina [14]

The correct pairing of DNA bases A. T with A, and C with G. Thus, option "A" is correct.

<h3>How, explain your answer briefly?</h3>

It can be explained with the help of complementary base pairing.

In DNA,  thymine (T) always forms a base pair with adenine (A) and cytosine (C) always base pairs with guanine (G) .

There are two hydrogen bonds present in between A and T and three hydrogen bonds in between G and C.

Thus, option "A" is correct.
