A - Ff and Ff is the answer
Answer: Option C) Determining the link between genes and the traits they influence.
Explanation:
First, the field of molecular biology seeks to understand the relationship between genes and proteins. Now, since genes are specific sequences on the DNA that codes for functional proteins, and these proteins make up the various traits physically expressed in living organisms such as skin color, blood group etc.
Then, the specific research goal of Carlita would be determining how genes control the expression of individual traits at the molecular level
The total volume of the gas-exchanging region in the lung is called alveolar volume.
The alveolus is an air sack-like organ in the end of the respiratory airway. The alveolus is the site where gas-exchanging happens, so only air inside alveolus that will undergo actual exchange. Air in bronchus or trachea wouldn't do exchange
Explanation:
Classification systems function in order to organize a group of organisms into smaller groups according to some kind of logic. For example, the most used classifications system in biology is the phyllogenetic, which classifies living beings according to their evolutive affinity.
In the other hand, a dichotomous key is a "guide" used by biologists when they need to indentify an individual. It is organized in several steps regarding some key characteristics in order to guide you to which species/genus/family your individual belongs to. A dichotomous key never provides any kind of trustworthy phyllogenetic information, and should be understood only as a tool.
