Is the Harvard Forest a carbon source or a carbon sink, and how has the net ecosystem exchange (NEE) changed over time?
Answer:
This is strong evidence that suggests that the forest acts as a carbon “sink”: each year, it removes more CO2 from the air than it produces.
Explanation:
There are different sources of carbon. Harvard Forest is known to be a carbon sink.
Harvard Forest is known to have active C sink that is due to the forest regrowth after land abandonment.
Net ecosystem exchange is known to be negative every year. but the result is shown to be very variable. Result also show a decrease over time and this implies that the forest is removing more CO2 from the atmosphere presently than before.
When you look at the data of the last 25 years, there is a pattern of NEE being negative and also many variability.

What is sodium thiosulphate?The inorganic compound sodium thiosulfate, sometimes known as sodium thiosulphate, has the formula Na2S2O3.xH2O.
It can be found as the pentahydrate which is white or colorless. The solid is a crystalline efflorescent (quickly loses water) substance that readily dissolves in water.
Gold mining, water purification, analytical chemistry, the creation of silver-based photographic film and prints, and medicine all make use of sodium thiosulfate.
The treatment of cyanide poisoning and pityriasis are among the medical applications of sodium thiosulfate. It is among the safest and most useful medications required in a healthcare system.
Therefore, Heat sodium thiosulfate in a water bath. The solid crystals will dissolve into the water in the hydrated crystals forming a supersaturated solution. Placing a small crystal in the supersaturated solution will cause the liquid to turn solid.

antibiotics are compounds capable of killing bacteria. how is this a biotechnology?
A. antibiotics are used to kill bacteria, which are alive.
B. antibiotics are used to treat sick humans, and humans are living organisms.
C. antibiotics are viruses that have been deactivated but we're once alive.
D. antibiotics were first isolated from a living origin: mold.
Antibiotics are compounds capable of killing bacteria. This is biotechnology because antibiotics were first isolated from a living origin: mold. The correct option is D.
What are antibiotics?When the body develops a resistance to antibiotics, antibiotic resistance happens. Antibiotic abuse or overuse is what led to antibiotic resistance. When germs develop resistance to medications meant to kill them, it happens.
Because antibiotics are unable to combat bacteria, the bacteria grow and produce illnesses that can result in life-threatening infections, incapacity, or even death.
The overuse or improper use of antibiotics was somehow the cause of all antibiotic resistance. It takes place when the bacteria completely lose their ability to be killed by drugs and instead develop a resistance to them.
Therefore, the correct option is D. antibiotics were first isolated from a living origin: mold.

which option would help maintain homeostasis during exercise?
Answer:
As your body converts food into energy during exercise, it produces heat as a waste product. This extra heat can elevate your body temperature above the typical 98.6 degrees. To maintain homeostasis, the blood vessels in your skin dilate to allow more blood flow to the surface of your body where it disperses the heat.Jan 10, 2019

How does thermohaline circulation force the thermocline toward the
ocean's surface?
Thermohaline circulation begins in the Earth's polar regions. When ocean water in these areas gets very cold, sea ice forms.
What is Thermohaline circulation?The thermohaline circulation (THC) is that part of the ocean circulation which is driven by fluxes of heat and freshwater across the sea surface and subsequent interior mixing of heat and salt.
What is polar region?The areas of the Earth that encircle its geographical poles and are contained inside the polar circles are known as the polar regions, sometimes known as the frigid zones as well as polar regions.
These deep-ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity. This process is known as thermohaline circulation. In the Earth's polar regions ocean water gets very cold, forming sea ice.Thermohaline circulation begins in the Earth's polar regions. When ocean water in these areas gets very cold, sea ice forms. The surrounding seawater gets saltier, increases in density and sinks. Winds drive ocean currents in the upper 100 meters of the ocean's surface.

If albumen is broken down by a protease, what sort of chemical is albumen?
Albumin is broken down by the activity of protease enzyme, this enzyme is responsible for the digestion of proteins. Therefore, albumin is chemically protein in nature.
What is Albumin?
Albumin is a family of proteins. These are globular proteins in which the most common are the serum albumins. All the proteins of the albumin family are water-soluble and moderately soluble in concentrated salt solutions. This protein denatures on continuous heat treatment.
Albumins are commonly found in blood plasma. It differs from other blood proteins as they cannot be glycosylated. Substances which contains albumin proteins are called albuminoids.
A number of blood transport proteins are found to be evolutionarily related in the albumin family such as serum albumin, alpha-fetoprotein, vitamin D-binding protein and afamin. This family of proteins is only found in vertebrates.
