Birds and mammals have a four-chambered heart, but most reptiles have a three-chambered heart. How does this fact affect the con
eduard

Answer:

The animals present body structure is due to evolution. It is seen in each part including the structure of the heart. The vertebrate heart becomes complex from a simpler form.  

Invertebrates, the heart of fishes is two-chambered having one auricle and one ventricle. The deoxygenated blood gets purified in the gills. They are aquatic and no lungs for breathing. The hearts pump a mixture of oxygenated and deoxygenated blood to the body.  

The amphibians and reptiles have 3 chambered heart as they lead terrestrial mode of life. The gills modified into the lungs.  The left auricle receives pure blood and the right auricle receives deoxygenated blood. The blood purified in the lungs and in the ventricle, both types of blood get a mix. The ventricle pumps the mixed-blood throughout the body.

In the case of birds and mammal, the heart is 4 chambered and the oxygenated and deoxygenated blood are separated. These two are higher vertebrates. No mix of pure and impure blood, the body receives only the oxygenated blood.

This shows to construct the phylogenetic tree of vertebrates - the fishes should be in the bottom, and above it amphibians, reptiles, then, mammals and birds on the top branch of the tree. As the chambers and structure of the hearts modified one after another.

maria [59]

Answer:

The correct answer is B. The virus can infect the host.

Explanation:

  • As the host and the virus both remain in the agar plate, the virus is capable of infecting the host cells.
  • The host cell multiplies and grows by utilising the nutrient from the agar medium.
  • After the virus particles infect the host, they replicate inside the host and produce new progeny virions which get released out of the host cell by killing it.
  • The newly formed virions infect other host cells and the process continues.
  • The killing of the host cells by the viruses result in the generation of clear zones on the agar plate which is also known as the zone of exclusion.
  • In the zone of exclusion region, the host cells have been killed by the viruses.

What are the sources of energy for the processes that affect Earth?​
marissa [1.9K]

Answer: ok so Most of the energy in the Earth system comes from just a few sources: solar energy, gravity, radioactive decay, and the rotation of the Earth. Solar energy drives many surface processes such as winds, currents, the hydrologic cycle, and the overall climate system. Gravity makes rivers and other materials flow downhill and creates tides (from the Moon's gravitational pull). Radioactive decay creates heat in the Earth's interior, while Earth's rotational forces influence currents of air and water.
