Answer:

The galaxies are moving away from Earth because the fabric of space itself is expanding. While galaxies themselves are on the move — the Andromeda Galaxy and the Milky Way, for example, are on a collision course — there is an overall phenomenon of redshift happening as the universe gets bigger.

Draw a phylogenetic tree demonstrating the evolution of the multi-chambered heart in fish, amphibians, reptiles, mammals, and bi

RSB [31]

<h2>Multi-Chambered Heart </h2>

Explanation:

The four-chambered in warm blooded mammals like frog's have three chambered of heart.
Other warm-blooded creatures, consume a great deal of vitality and need a lot of oxygen.This change bears the turtle's body blood that is somewhat more extravagant in oxygen than the frog's.

Advantages of fish-

The heart doesn't require extra chambers past the initial two.
Fish and different creatures with 2-chambered hearts, along these lines, have less difficult circulatory frameworks than creatures with lungs and therefore, 3-and 4-chambered hearts.

Advantages of Amphibians-

The amphibians have a three chambered of the heart which to be very helpful to amphibians of land and water.

Advantages of Reptiles-

The reptiles have a three-chambered heart comprising of one ventricle and two atria.
The chamber called the correct chamber gets d<em>eoxygenated, or "spent," blood coming back from the body tissues. </em>

Advantages of Mammals-

The four-chambered heart of feathered mammals and well evolved creatures advanced freely from a three-chambered heart.

Advantages of Birds -

Birds like mammals , similar to vertebrates, have a 4-chambered heart (2 atria and 2 ventricles), with complete division of oxygenated and de-oxygenated blood.
The correct ventricle siphons blood to the lungs, while the left ventricle siphons blood to the remainder of the body.
