Answer:
as causas de las extinción de una especie pueden ser muchas, como la destrucción de su hábitat natural, la caza o captura de animales exóticos, la contaminación, la deforestación (la desaparición de los bosques por la tala de árboles) o el cambio climático, que son consecuencia de la intervención de los seres humanos. Aunque esto también puede relacionarse con distintos fenómenos naturales como inundaciones, incendios, o la llegada de enfermedades.
Explanation:
En algunas ocasiones y por diferentes motivos, las especies de animales empiezan a desaparecer, y esto se conoce como extinción. A pesar de que escuchamos esta palabra muy a menudo, alguna vez te has preguntado, ¿por qué una especie se extingue y qué pasa cuando esto sucede?
The answer is C.Petroleum I hope this helped ^^
When you scrape your original sample onto your agar plate, you cannot see how much single bacteria or where the individual bacteria is on your plate- since it's invisible to the naked eye. But when the bacteria start to multiply, you start to see the individual colonies. (from the single bacteria, it begins to multiply within 20 min. maybe after 1-2 days you'll see a colony, meaning there are millions of bacteria)
for example, if you take a water sample and spray it onto an agar plate, you won't know which parts of the agar plate the bacteria landed on. however, when they start to multiply from a single bacterium, you'll see where each starting bacterium was because now you can see a whole bunch of bacteria. (remember that a colony contains millions of bacteria- which allow it to be visible to the naked eye).
so you count the number of colonies, and that'll tell you how much bacteria you started with. if you look at the size of the colonies, you're only looking at how long you allowed the bacteria to incubate (since from the single bacteria that you started with, it's only multiplying and growing outwards).

Answer:
C. Scavenging of dead animals and gathering of plants (just as Homo <em>habilis</em> had done), and perhaps the hunting of smaller animals
Explanation:
Homo <em>erectus</em> (erect man): Homo erectus is believed to be appeared about 1.5 million years ago. It was in the middle Pleistocene age when they evolved from homo habilis. Homo erectus probably ate meat, was around 1.5-1.8 meters tall and males were probably larger than females. As the name suggests they has erect posture. His skull was flatter than that of modern man and he had protruding jaws. Other features includes projecting brow ridges, small canines and large molar teeth. Their cranial capacity was 900 cc. Cranium was dome shaped to accommodate the large brain. Homo erectus was omnivorous and he made various tools using stones and bones. He made use of fire for hunting, defense and cooking. Homo erectus inculdes three fossils: Java Ape-man, Peking man and Heidelberg man.
