Lloyd came up with the idea of Tragedy of the Commons
The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.
Hope this help
Hi!
The correct option would be A. There's lower biodiversity among birds
Biodiversity refers to the variety of organisms (species) that inhabit a particular place, such as in our case different species of birds.
From the graph we can see that over time, the bird species are declining. From roughly 1700 bird species, the number has fallen to about 200 bird species by the middle of the fourth year.
Hence, we can deduce, and it would be accurate to say, that there is a relatively lower biodiversity amongst the birds with regard to that in the beginning.
Option B is incorrect because if the birds had a higher reproductive rate, they would be able to make up for the loss of bird species from the habitat. From the graph, we can assume that there's a moderately low reproductive rate among the birds.
Option C is incorrect because we do not know the affect of this pollution on the producers (photosynthesizing plant lifeforms). It may be possible that they might be declining, but we cannot conclude that solely from the graph.
Hope this helps!
Mass movements (also called mass-wasting) is the down-slope movement of Regolith (loose uncemented mixture of soil and rock particles that covers the Earth's surface) by the force of gravity without the aid of a transporting medium such as water, ice, or wind.
The rate at which it moved
The type of motion is the most important characteristic of a slope failure, and there are three different types of motion:
If the material drops through the air, vertically or nearly vertically, it’s known as a fall.
If the material moves as a mass along a sloping surface (without internal motion within the mass), it’s a slide.
If the material has internal motion, like a fluid, it’s a flow.
The correct answers are:
• transcribe RNA that combines with a protein that has a DNA-cleaving function.
• identify viral DNA by complementary base pairing with template DNA.
CRISPR is a DNA sequence found in bacteria (or other prokaryotic cell), derived from DNA fragments from viruses that have previously infected that bacteria. Bacteria use CRISPR to destroy DNA from next similar viruses. So, it is form of antiviral defense in bacteria.
Cas9 is an RNA-guided DNA endonuclease enzyme (DNA-cleaving function) associated with the CRISPR that cleave specific sequences of DNA complementary to the CRISPR sequence.
