Answer:
Your answer is probably A). If you find a fossil of an armored fish in layer A, and you find a fossil of a trilobite in layer B (five layers deeper), then you can safely assume that the trilobite is older than the armored fish.
Carbohydrates are your body’s main source of energy. The amount of carbs a man should consume daily depends on his age and activity level. The Institute of Medicine suggests adults to eat at least 130 grams of carbs a day. But If you’re a competitive athlete like Shana, you need additional amount.
<span>A study made by The Academy of Nutrition and Dietetics recommends a 2.3 to 4.5 grams of carbohydrates per pound of body weight each day, to athletes depending on the intensity of training. Therefore, Shana who weighs 135 lbs, needs approximately 310.5 grams carbohydrates daily for her physical workouts. </span>
Answer:
pindle fibers form a protein structure that divides the genetic material in a cell. The spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells during both types of nuclear division: mitosis and meiosis. During mitosis, the spindle fibers are called the mitotic spindle.
Explanation:
Answer:
X is negative heterotropic modulator
Explanation:
In allosteric regulations, modulators are molecules that causes a change in the conformation of an enzyme, hence, resulting a change in enzyme activity. It can lead to a decrease or an increase of the enzyme. When a molecule decreases the enzyme activity it called a negative modulator, when it increases or activates the enzyme activity, it is called a positive modulator.
A positive or negative modulator can either be homotrophic (substrate acts as modulator) or heterotropic (another ligand acts as modulator).
In the example above, X is negative heterotropic modulator, because the modulator is different from the substrate and it also decreases the enzyme activity.
Answer: "Articulating" means that the bones are moving relative to each other at a joint.
