Answer:
Una cadena alimentaria es una secuencia lineal de organismos a través de la cual los nutrientes y la energía pasan de un organismo a otro mediante consumo. ... Las redes tróficas consisten de varias cadenas alimentarias interconectadas y son una representación más realista de las relaciones de consumo en los ecosistemas
Explanation:
A food chain is a linear sequence of organisms through which nutrients and energy pass from one organism to another by consumption. ... Food webs consist of several interconnected food chains and are a more realistic representation of consumption relationships in ecosystems
Answer:
1,2 and 4 are correct
Explanation:
Enzymes that show cooperativity are defined as Allosteric enzymes. This cooperativity is of several types.
1) homotropic/homoallestery - positive cooperation
2) heterotropic/heteroallestery - negative cooperation
Activity of allosteric enzymes is regulated by other molecules (effector molecules)
Hence, statement 1 and 2 are correct.
Binding curve of allosteric enzymes:
For cooperative binding, binding curve is Sigmoidal curve
For non cooperative binding, binding curve is Hyperboilc curve.
Hence, statement 3 is wrong.
Allosteric enzymes have multiple active sites.
Allosteric enzymes are often multi sub unit proteins.
Hence, statement 4 is correct.
Answer:
Explanation:
We are asked to find the density of a metal. Density is the mass per unit volume. It is calculated by dividing the mass by the volume.
The mass of the metal sample is 24.64 grams and the volume is 5.91 milliliters. We can substitute these values into the formula.
Divide.
The mass measurement has 4 significant figures the volume measurement has 3 significant figures. Our answer for density must match the least number of significant figures, which is 3.
For the number we calculated, that is the hundredth place. The 9 in the thousandth place tells us to round the 6 up to a 7.
The density of this metal is approximately <u>4.17 grams per milliliter.</u>
