Answer:
Pressure is simply the force experienced by an object divided by the area of the surface on which the force acts. Note that the force here is the force acting perpendicular to the surface. The unit for pressure is the pascal, Pa.
Explanation:
The fossils that provide information on the formation of an oxygen-rich atmosphere are the stromatilites from the Precambrian era. These are layered and columnar fossils consisting mainly of cyanobacteria which were the original life form back then. These bacteria took in carbon dioxide and produced oxygen by photosynthesis as early as 2.5 billion years ago (the earth is about 4.5 billion yrs old).
Answer:
Amino acids, often referred to as the building blocks of proteins, are compounds that play many critical roles in your body. They're needed for vital processes like the building of proteins and synthesis of hormones and neurotransmitters
Explanation:
Diffusion is a passive process. Passive transport
Answer:
Antibiotics are routinely introduced into the food of cattle, chickens and other livestock, which causes the animals to grow faster but the negative effect of using antibiotics is the development of antibiotic-
resistant bacteria.
When we use antibiotics at large scale some bacteria that live in these cattle become resistance to these antibiotics and then these resistant bacteria are shed in the soil through poop of animals.
Bacteria have the capability to transfer antibiotic-resistant genes to other bacteria by horizontal gene transfer mechanism so it can give rise to more antibiotic-resistant bacteria which can infect humans.
So when these resistant bacteria infect humans then if we take the antibiotics which the bacteria are resistant for then the antibiotic will not able to protect the patient.
Therefore, this practice could affect the probability of developing populations of antibiotic-resistant bacteria that cause human disease.
