Answer:
the evolutionary time between two nodes
Explanation:
Branch lengths indicate genetic change i.e. the longer the branch, the more genetic change (or divergence) has occurred
Answer:
The number of bonds for a neutral atom is equal to the number of electrons in the full valence shell (2 or 8 electrons) minus the number of valence electrons. This method works because each covalent bond that an atom forms adds another electron to an atoms valence shell without changing its charge.
Answer:
The study of living things.
Explanation:
Biology is known as natural science which helps to study the life of living things along with some characters such as development in characters, evolution in species, chemical processes inside the body, physical body structure, and molecular interaction between the ions.
Living species such as animals, plants are known as an open system that has the ability to survive by lowering entropy and transforming the energy to sustain stable homeostasis. Biology helps us to identify the basic unit of life which is known as cell and for creation and extinction of living organisms.
Answer:
C3 photosynthesis produces a three-carbon compound via the Calvin cycle while C4 photosynthesis makes an intermediate four-carbon compound that splits into a three-carbon compound for the Calvin cycle. Plants that use CAM photosynthesis gather sunlight during the day and fix carbon dioxide molecules at night.
