A pure culture consists of only one type of microbe while a mixed culture has two or more than two microbes.
Explanation:
A pure culture consists of only one type of microbe.
While a mixed culture consists of more than one type of microbes. such cultures may comprise of different species of bacteria or a group of bacteria, viruses and other pathogens.
In mixed culture the microbe species living together may harm each other existence.
An air mass that originates in the Pacific ocean, west of Brazil, is most likely WARM AND WET.
A. warm and wet
<u>Explanation:</u>
The pacific ocean has the tropical maritime air mass so it is warm and wet. they affect the United States originate over the Caribbean sea, Mexico, pacific and the western Brazil.
So the air masses in the pacific ocean, western Brazil are wet and warm.the air masses have the fairly uniform temperature and the moisture content in the horizontal direction.
Air masses are characterized by their temperature and the humidity properties. The air mass where the originate is based on the surface properties.
Answer:
a .carbon dioxide(Co2) and water (H2O)
b. air and soil
Explanation:
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
Answer:
The main difference between relative dating and radiometric dating is that relative dating is the method used to determine the age of rock layers according to their relative depth whereas radiometric dating is the method used to determine the absolute age with the use of decaying products of the natural radioactive. Also, absolute dating is more precise than relative dating because it tells the exact age of the fossils. Both are ultimately based on the fossils found in the strata.
