Answer:
A. Dominant alleles often encode functional products, whereas recessive alleles often do not encode functional products
Explanation:
One gene can have it's variant forms called allele but in one individual only two allele form of a gene can be present. These two allele form can be the same(homozygous) or different(heterozygous). A dominant allele often encode a function protein of product while recessive allele often code for non- functional product.
Therefore when the dominant allele is present in the chromosome then function products are formed which can be seen in the phenotype and even a single dominant allele produce the functional product like in heterozygous condition so phenotype in heterozygous and homozygous dominant condition appears same. So the correct answer is A.
If the Independent Variable, then the Dependent Variable:
Your IV is how safe/supportive your design for your egg is
Your DV is what you believe/want the outcome to be after you drop the egg
So (an example could be):
If the structure of the apparatus that holds the egg is built of inflated balloons, then the egg will not crack when it is dropped.
Answer:
It is not necessary that both partners get equal benefits from each other.
Explanation:
Mutualism is a symbiotic relationship between two individuals. In mutualism both the partners get benefitted from each other but it is not necessary that both get equal benefits from each other.
Every mutualistic relationship is different and in all mutualistic relationships, altruistic behavior is not seen by any partner species. Each partner is selfish and help the other partner unintentionally in mutualism. So it is not necessary that each partner gain equal benefit in this relationship.
The answer is A, the more you test an experiment, the more trustworthy it is.
