Answer:
The evidence that supports the big bang theory is that uniform background radiation, known as cosmic microwave background radiation, is detected coming from all parts of the sky. Most galaxies are moving away from us except for the Andromeda galaxy. In fact, the galaxies that are farthest away are moving away from us the fastest.
Explanation:
The six types of physical weathering are
Abrasion weathering.
Exfoliation weathering.
Frost wedging.
Salt crystallization.
Thermal expansion.
Biological activity/root wedging.
Origins and early evolution of herbivory in tetrapod's About 300 million years ago, in the Late Carboniferous, the first herbivorous tetrapod's evolved. By the Late Permian, continental ecosystems of `modern' character had been formed, with a massive standing crop of herbivores sustaining relatively few predators. In order to process high-fiber plant material, it is necessary to make anatomical changes to the jaw, digestive system, and dentition as well as to acquire microbial endosymbionts that can create the enzymes required for fermentative digestion of cellulose, the main component of plant cell walls. Recent tetrapod phylogenetic studies show that several lineages separately developed endosymbiotic cellulitis throughout the late Paleozoic.
What is tetrapod's?
Animals classified as Sarcopterygii include tetrapod's. Tetrapod's, which include hawks, frogs, and turtles, are land-dwelling creatures. Along with such, there are marine creatures including sea lions, whales, sea snakes, seals, dolphins, and sea turtles.

Answer:
Explanation:
Crossing over is the swapping of genetic material that occurs in the germ line. During the formation of egg and sperm cells, also known as meiosis, paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another
<span>7. which, if any, of the blood samples tested cna the patient with type b+ blood receive? explain why.
It can't be answered because you didn't put the sample test result
8. explain how you were able to use your knowledge of how different types of blood react with anti-a, anti-b, and anti Rh antibodies to determine the blood types of the four samples.
If the blood react with anti-a, then the blood must not have A antigen
</span>If the blood react with anti-b, then the blood must not have B antigen
If the blood react with anti Rh, then the blood must not have Rh antigen
Based on the antigen, you can conclude the result as:
react with anti A= blood type B
react with anti B= blood type A
react with anti A and anti B= blood type O
react with anti Rh= Rh-
not react with anti Rh= Rh+

9. if a person has type a blood, he or she would have antibodies for what blood type?
Type A blood has antigen A. So that person should not have anti-A antigens.
The person should have anti-B antibodies because it was a foreign object to him. Depends on the Rhesus type, he can have Rh antibodies too.
10. why is type o negative blood known as the universal donor? why is o positive not a universal donor?
Type O blood doesn't have antigen-A or antigen-B. That means the blood cells won't trigger any reaction on Type A, B, AB, or O blood. Negative rhesus also means that the blood is safe for Rhesus negative or Rhesus positive type.
Positive O blood type has rhesus antigen, so it will trigger a reaction in Rhesus negative type. </span>
