Answer:Answer:
For 1: The correct answer is Model 1, 2, and 4.
For 2: The correct answer is Option 1.
Explanation:
For 1:
An element has 3 subatomic particles: electrons (E), neutrons (N) and protons (P).
Atomic number is defined as the number of protons or number of electrons.
Atoms having same number of protons are same. From the given models, Model 1, 2 and 4 have 2 protons with different neutrons. Hence, these models belong to same element.
For 2:
A compound is defined as a substance in which two or more types of elements combine in a fixed ratio. For Example: is a compound made out of atoms of carbon and oxygen.
Hence, the correct answer is Option 2.
Answer:
Renewable resources can become nonrenewable resources if they are used faster than they can be replenished. If the resource no longer exists, there is nothing to regenerate or be replenished. For example, if we cut down trees faster than we grow them, trees can become a nonrenewable resource because there are no trees to regenerate.

Answer:
They are called decomposers.
Explanation:
The genotype for the possible children is 'AATt, AAtt, Aatt, AaTt'. Woman has normal pigment which means she must have at-least one' 'A. her father is albino and albino allele is recessive , so his genotype is 'aa'. Then 'Aa' genotype is present in skin.
Woman cannot taste PTC because the ability ti taste PTC is dominant .So 'tt' genotype is present for tasting trait. Putting both the trait the woman's genotype is 'Aatt'.
(PTC) Phenylthiocarbamide tasting is a trait governed by pair of alleles , 'T' is for tasting dominant and recessive 't' is for non- tasting.The genotype of parents perform a punnett square to determine the F1 offspring. And the genotype of possible children can be determine.
