2. What biosecurity measures does the hatchery take?<br> Enter your answer
Cloud [144]

Answer:

Provide a closed environment.

Clean the hatch chamber with chemical.

Explanation:

Biosecurity  is a measure which is taken in order to protect or prevent the population of existing species from infestation of harmful organisms and chemical substances. The hatchery should provide a closed environment in order to prevent the entry of harmful organism. Cleaning of the chamber where eggs were hatched with chemicals in order reduce the infestation of microorganism.

Theodor W. Engelmann illuminated a filament of algae with light that passed through a prism, thus exposing different segments of
WARRIOR [948]

Answer:

The correct answer is C and Engelmann conducted this experiment to prove relationship between algae and the rate of photosynthesis.

Explanation: First we must talk about 3 facts:

1) Prism scatters the white light into different wavelengths.

2) Photosynthesis, 6 carbon dioxide and 6 water molecules are consumed and 6 oxygen and 1 sugar molecule is synthesized using light energy.

6CO2 + 6H2O → C6H12O6 + 6O2

3) Aerobic bacteria breaks down sugar while using oxygen and produces water and carbon dioxide in simplified terms.

So with this experimental setup a researcher can understand the rate of the photosynthesis by increased accumulation of aerobic bacteria near algae  in certain wavelengths since they uses oxygen and tend to move close to the oxygen source (<u>see figure</u>). In this experiment there are no ways to measure heat (B), there is no known relation between wavelength of light and aerobic respiration since it can happen even in the dark (A) and finally there are no ways to measure carbon dioxide (D).

Which amino acids are the primary nitrogen donors for biosynthetic reactions in the cell?
prohojiy [21]
Glutamine and glutamate are the primary nitrogen donors for biosynthetic reactions in the cell.  Glutamine is an α-amino acid that is used in the biosynthesis of proteins. Its side chain is similar to that of glutamic acid, except the carboxylic acid group is replaced by an amide. It is classified as a charge-neutral, polar amino acid. It is non-essential and conditionally essential in humans, meaning the body can usually synthesize sufficient amounts of it, but in some instances of stress, the body's demand for glutamine increases, and glutamine must be obtained from the diet. Glutamate is generally acknowledged to be the most important transmitter for normal brain function. Nearly all excitatory neurons in the central nervous system<span> are glutamatergic, and it is estimated that over half of all brain synapses release this agent. Glutamate plays an especially important role in clinical neurology because elevated concentrations of extracellular glutamate, released as a result of neural injury, are toxic to neurons</span>

Drilling for fossil fuels.

This is because the main fossil fuels are not typically found in the rainforest. To also back up this claim, use the process of elimination.

The last choice, demand for rainforest products, is obviously incorrect as that would mean expansion into the rainforest to gather said products.

Shortage of food sources wouldn't be the correct answer either as food sources aren't typically found in the rainforest among popular demand and food can be shipped into the country as well. 

Overcrowding in cities would also lead to expansion, where to can differ based on location but to rainforests or anywhere surrounding the area would be preferred or desirable.

Hope this helps!

How do identify veins in our body​
Alexandra [31]

Answer:

Veins are blood vessels in humans, and most other animals that carry blood towards the heart. Most veins carry deoxygenated blood from the tissues back to the heart; exceptions are the pulmonary and umbilical veins, both of which carry oxygenated blood to the heart. In contrast to veins, arteries carry blood away from the heart.
