Answer:
The molecular structure of complex macromolecules show that a chemical reaction has occurred.
Explanation:
A macromolecule is defined as molecule containing a very large number of atoms, such as a protein, nucleic acid, or synthetic polymer.
Macromolecules are formed by chemical reactions between simple molecules which join together to give the macromolecule.
If we look at the structure of a macromolecule very closely, we will discover evidences that show that the complex structure of the macromolecule was created by stepwise chemical reactions.
Answer:
IgM
Explanation:
The first molecular mechanism of adptative immunity to appear is IgM. These molecular pentameric (constituted of 5 smaller units), are produced in the macrophages of the organism and are released when some time has elapsed since the beginning of the infection (latency period). By having 5 possible epitopes, it increases the chances of triggering a cell-mediated immune response and stimulating the production of IgG.
Abrasion, plucking, deposition, and physical weathering are the glacial actions which can be observed all over the park.
Explanation:
When the huge ice masses slope down to fall over the land surface during a glacier, many glacial actions or processes take place which defines the landforms formed on the surface. These actions include abrasion, plucking, deposition, and physical weathering.
Abrasion is an erosive process which scrapes the surface of ice rocks and other frozen rocky material beneath the ice and causes striations over the rocks.
Plucking also an erosive process plucks the frozen rocks beneath the ice surface.
Physical or freeze-thaw weathering causes water to enter the cracks in the rocks when the temperature increases. This water enters inside and freezes inside when the temperature goes down. This repeated melting and freezing of water destabilizes the rocks and will break the rocks.
These materials which are worn off are transported and deposition on the land surface when the glacier settle down.
Longshore drifts occur along coastlines and brings materials along the coast when waves move at an angle with the coastline.
Answer:
There was no oxygen in the flask.
Explanation:
Anaerobic organism do not need oxygen!!
