The water vascular system of a sea star enables movement, digestion and respiration through the use of water to exert force on limbs known as tube feet. The vascular system is primarily water but also contains coelomocytes, protein and potassium salts.
Answer:
The potential risks associated with plant-based pharmaceuticals include: pollen transfer to related species, contamination of non-transgenic crops intended for the consumption by humans, allergic reactions to the drugs produced from the genetically engineered plant, and persistence of genetically engineered material to persist in the environment and accumulate in non-target organisms. Risk assessment of plant-made pharmaceuticals should be reviewed on a case-by-case basis because the plants used to produce proteins each have different risks associated with them.
Protein, the building blocks of proteins are amino acids, different sequences and combinations of these amino acids result in huge numbers of proteins which have a variety of functions.
Answer:
A scientific law is simply an observation of the phenomenon that the theory attempts to explain. For example, suppose that you were lying under an apple tree and observed an apple fall from a branch to the ground. The observation of this phenomena can be called the law of gravity.
Answer:
Average annual temperature in US cities would range between 50-70 degrees Fahrenheit
Explanation:
There are several factors that can influence the temperature of city in general. Higher altitude has a lower temperature because it has less air density and absorbs less sunlight. The city latitude coordinate also determines how much sunlight they will get. The closer the city to the equator, the more sunlight they can get.
Distance to the sea will influence the rate of rainfall and also influence temperature. Ocean currents can move hot water from other regions too.
