Yes, the statement is indeed true.
Answer:
Cells within a large multicellular organism communicate through chemical signals. These signals are relayed from one cell to another. A cell must have a receptor for that chemical to interpret and respond to a signal.
Explanation:
To initiate a physiological response, all body cells possess specific proteins known as receptors. These receptors are essential for detecting chemical signals and eliciting responses. Different receptors are tailored for various chemical signals; for instance, a dopamine receptor engages with dopamine molecules, whereas an insulin receptor specifically binds to insulin molecules. Additionally, certain cells may also respond to mechanical signals.

Answer:
Brachydactyly and Huntington's are phenotypic conditions that occur when a person possesses one or two dominant alleles for those traits.
John's father has Huntington's disease but does not have brachydactyly, which means his genotype is Hh/bb.
John's mother, who is healthy and has brachydactyly, likely has a genotype of hh/BB or hh/Bb.
A food safety hazard refers to any element present in food that poses a risk to consumers. Such hazards can be biological, chemical, or physical. Their presence may lead to both illness and injury. Specifically, if a cleaning solution is used on a frozen yogurt machine, it must be handled carefully, as it may contain harmful chemicals. These substances can enter the body and lead to serious health issues, classifying this scenario as a chemical food hazard. To mitigate these risks, proper cleaning of the solution after use is essential.
