This question had choices. These are the missing choices.
A) Scientists made careful observations of behavioral patterns.
B) The DNA mutation rates for both species was calculated and compared.
C) Scientists made a detailed analysis of the fossilized bones of each species.
D) The enzyme activity of each species was studied to determine similarities in metabolism.
My answer:
C) Scientists made a detailed analysis of the fossilized bones of each species.
This determination is the only feasible thing to do since dinosaurs are long dead and choices A, B, and D requires the subjects to be alive.
Answer:
The correct answer is: the mass in grams of one mole of a substance
Explanation:
The molar mass of a given substance corresponds to the mass of one mole of this in grams. Corresponds to a physical property of the substance. Example: the molar mass of water (H20) is:
Molar mass H20 = (Mass H) x 2 + Mass 0 = 2 x 1 g + 16 g = 18 g / mol
Answer:
D. Cytokines
Explanation:
I would utilize Cytokines to recruit more leukocytes to the battle.
Cytokines are important chemical messengers that act via receptors in the immune system of the body. They are a group of proteins made by various immune cells. Immune cells communicate through Cytokines in regulating immune response
As you move up to the food chain, the energy will decrease. This explains that the more the consumers, the lesser the energy that the last consumer will get from the sunlight. This is because each energy will decrease as it passes by the consumers because each consumers takes a portion of the full energy from the sun.
Weathering causes the granite to break down into small particles - sand. The sand becomes buried and compacts into sandstone. If the sandstone continues to be buried and comes into close contact with high heat, such as magma, it can be turned into quartzite.
