The answer is C, hope this helps!
This pedigree supports the fact that widow's peak is due to a dominant allele because if it were due to a recessive allele and both parents show the recessive phenotype, then <u>all of the offspring would have a widow's peak.</u>

<h3>What is the widow Peak gene?</h3>
A widow's peak is a distinctive, V-shaped hairline that tends to run in families. Despite the myths, it's probably no more significant than other genetic traits such as curly hair or a cleft chin. Some people prefer to downplay their widow's peak and some want to show it off.
The following genetic disorders are linked to the widow's peak: Arskog syndrome is a rare genetic condition that primarily affects men. Children with Aarskog syndrome have short stature in addition to deformities of the face, limbs, and genitalia.
There is a 75% likelihood that any of the offspring of parents who are heterozygous (Ww) will have a widow's peak.

Answer: d. Perform a windshield survey
Explanation:
Environmental health risks include air pollution, disease vectors, lack of water and inadequate sanitation, electronic waste, and chemical hazards.
Conducting a windshield survey is a valuable first step in identifying possible safety threats to the environment. This offers first-hand neighbourhood information and areas of concern which need to be investigated.
Hence, the correct option is d.
The decreasing wolf populations in North America can result to the <span>range expansion of coyotes
</span><span></span>Wolves and coyotes usually compete for prey, especially the smaller mammals. Wolves do not actively hunt coyotes but do attack them when the latter ventures into their territory.
With decreasing wolf populations, coyotes can then venture and hunt more freely. However, the coyotes cannot take the place of the wolves in helping maintain balance in the ecosystem in which they belong to because of their preference for smaller mammals.
Wolves can help regulate an ecosystem's larger mammals such as the ungulate populations, as they do not prey on the smaller mammals as much as coyotes do. This leaves more prey available for mid-level carnivores like foxes. Moreover, wolves also leave behind carcasses of their prey, which become food for other animals such as <span>foxes, badgers, raptors, coyotes and other scavengers.</span>
