Answer:
The answer is B - Tap water can be found in the natural environment, but what the lab technician is testing is if there is lead in the water. This part is not related to biology therefore making B the answer.
Explanation:
Biology is the study of living organisms and life.
Every other answer is related to Biology.
A - A vitamin that helps with vision - this will affect the human vision to become better after taking it; this relates to biology because it involves the interaction of humans and the human body system.
C - Change of environment - this deals with the bird's environment and how they live and breed, which is in biology
D - Growing coffee to reduce harm to the rainforest - this deals with biology because it is taking about the environment and how certain changes will affect how it will thrive.
E - DNA - this is involved in human and other organism's systems and is related to biology.
Better adapted organism includes weeds, will replace some or all of the planted flower species.
Answer:
a) HT
Explanation:
This question shows an animal with two distinct unlinked genes i.e. on different chromosomes. One gene codes for head shape and the other for tail length. The gene for head shape possess alleles H and h, while gene for tail length possess alleles T and t.
According to Mendel's law of independent assortment, the alleles of a gene will separate into gametes independently of the alleles of another gene. This occurs in such a way that each gamete will contain only one allele from a gene.
Based on this principle, an animal with genotype HhTt will undergo meiosis and randomly produce gametes with the following allelic combinations: HT, Ht, hT, and ht. As seen in the gametes, only one allele of a gene occured in a gamete at a time.
Therefore, HT is the genotype possible in a gamete of parent: HhTt.
