Answer:
The correct answer is carbon dioxide.
Explanation:
Respiration (physical) process involves inhalation and exhalation of oxygen and carbon dioxide respectively in between the air and into the lungs to the blood. If the brain receptors sense the excess amount of carbon dioxide in the blood, they send signals the body to promote ventilation. So, the most important chemical regulator of respiration is carbon dioxide that determines the respiratory rate.
An increase in carbon dioxide concentration in blood results in a decreasing pH level of the blood, causing the person to increase his rate of ventilation.
Thus, the correct answer is carbon dioxide.
Answer:
The best answer to the question: Which term describes the individual in a pedigree whose phenotype was first brought to the attention of a medical researcher? would be: Proband.
Explanation:
The reason for this being the correct answer is that a proband, also known as proposito (for males) and proposita (for females) is known as the first member of a group (animal or human), most likely a family member, on whom a particular condition is appearing, and who is the first to seek medical help for it. The pedigree is further formed starting from the proband and relationships in groups and families to the proband are built with proper symbols to denote the relationship existent. In males the symbol used is a square and in females a circle. Usually these probands are used to study genetic disorders and the relation with the entire family group that springs forth from that proband.

Answer:
The interaction between cellulose-digesting organism in the gut of a termite and the termite is +
Explanation:
This relationship that exists between termites and the organisms present in their gut that are capable of degrading cellulose is a relationship called mutualism. Mutualism is part of the biological interactions in which both organisms benefit from the coexistence of both. For this reason this relationship would be positive.
The food of termites is wood, but they cannot produce the enzymes they would need for degradation of the wood. Thanks to this, there are small organisms called protozoa that are found in the intestine of the termites that allow them to degrade the cellulose present in the wood, these organisms help them to degrade the cellulose that by themselves they could not do since termites do not contain the cellulose enzymes responsible for cellulose degradation .In this way TERMITES can get what they need to perform its metabolism and biological functions.
