Answer:
- 4 out of 16 guinea pigs would have white hair.
- 12 out of 16 guinea pigs would have short hair.
Explanation:
This question involves two genes. One coding for hair color and the other for hair length in guinea pigs. The alleles for black and white hair are B and b respectively while the alleles for short and long hair are S and s respectively.
Based on this question, two parents that are heterozygous for both genes (BbSs) are crossed (as seen in the attached punnet square). The guinea pigs that have an allelic pair of bb have white hair while those that have an allelic pair of SS or Ss have short hair as described in this question.
Using the punnet square attached,
- 4 out of 16 guinea pigs would have white hair because 4 offsprings possess the genotype bb for the first gene.
- 12 out of 16 guinea pigs would have short hair because 12 offsprings possess the genotype SS or Ss for the second gene.
Answer:
1. Food / nutrients
2. Autotrophs
Explanation:
The word "autotroph" means "automatic nourishment", a word of greek origin. Autotrophic organisms are a group of organisms that don't need to find / hunt their food, since they can make it using the radiation (energy) provided from the sun along with other elements.

Answer:
a. Coded for on the X and Y chromosomes
b. Coded for on the X but not Y chromosome
c. Coded for on the Y but not X chromosome
Explanation:
The X and Y chromosomes are the sex chromosomes as they are involved in sex determination. All the genes that are present on the X and Y chromosomes are inherited along with these chromosomes and therefore, exhibit sex-linked inheritance.
X and Y chromosomes share a homologous region. Therefore, the sex-linked genes are defined as the ones present on both X and Y chromosomes as well as the ones that are present on either X or Y chromosomes.
For example, the gene for hemophilia is present on the X chromosome; but not on the Y chromosome. The SRY gene is present only on the Y chromosome.
Answer:
The energy stored in the living organisms in the chemical bonds.
Explanation:
The energy in the living system is stored in the chemical bonds. The chemical bonds are covalent in nature. The energy that is stored is extracted when these bonds break and use by the body of organisms in performing different functions. The body stored energy in the form of glycogen and triglycerides.
