The biosphere. This is the layer that contains all life on the planet.
Below are the choices, the answer is no. 3:
1) The virus was descended from a common ancestor of bird, pig, and human flu viruses.
2) The infected individuals happened to be infected with all three virus types.
3)Related viruses can undergo genetic recombination if the RNA genomes mix andmatch during viral assembly.
4)The human was likely infected with various bacterial strains that contained all three<span>RNA viruses.</span>
It is observed that the human population keep increasing significantly and it began to increase noticeably around 10,000 years ago.The greatest factor of this increase is the rapid development of the agricultures in lands, as well as the domestication of animals. These are the reasons why population increases at that time.
Answer:
Consumers use chemical energy from the chemical bonds within organic molecules such as carbohydrates, lipids, and amino acids.
Explanation:
<u>Heterotrophs are consumers</u>; they ingest or absorb organic matter (lipids, carbohydrates, proteins, etc.) made by autotrophs or producers for their energy consumption. Autotrophs include plants, bacteria, and other photosynthesizing organisms, while heterotrophs include animals, fungi, protists, and bacteria.
Heterotrophs obtain energy from food through the process of cellular respiration. For instance, during aerobic respiration in mitochondria, they break down sugars in the form of glucose into carbon dioxide and water to obtain energy in the form of ATP or adenosine triphosphate.
aerobic respiration: C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
glucose+ oxygen → carbon dioxide+ water+ energy
It would likely be cold...
Maybe 40 or 30 degrees?
