We must first define these three prominent definitions of species. Biological species concept means that organisms resemble each other because of genes being passed from parent to offspring. Phylogenetic species concept means that organisms resemble each other because they evolved from a common ancestor. Lastly, morphological species concept characterizes species on the structure of their body parts rather than genetic or phylogeny.
In this case, (1) biological species concept is not applicable for extinct species, (2) phylogenetic species concept is based on evolutionary history, (3) morphological species concept relies on similarities in structure, (4) Morphological and phylogenetic species concept accommodates asexual reproduction, and lastly (5) all species concepts are used by scientists in classification.
Answer:
All of the above----------
Answer:
G, S, G2, M
Explanation:
Cell cycle refers to the orderly events that prepare the cells for cell division and finally divide the parent cells into the daughter cells. The cell cycle consists of two stages: interphase and M phase.
Interphase is the phase wherein cells prepare to enter the M phase. Interphase has three stages: G1, S, and G2.
G1 is the first gap between represents the time between the end of mitosis and the beginning of the S phase. During the G1 phase, normal growth and metabolism take place. G1 phase is followed by the S phase, the synthesis phase, during which DNA replication and synthesis of histone proteins occur.
The cells then enter the G2 or the second gap during which cells synthesize more proteins and prepare to enter the M phase.
M phase is the phase of nuclear division that divides the nucleus of the parent cell into 2 or 4 daughter nuclei (depending on the type of the cell division that the parent cell has entered).
Therefore, the sequence of the stages that the cell will go through is G, S, G2, and M.
Answer:
A. metabolism
Explanation:
Metabolism is the bodily process used to convert food into energy.
To survive, the body must use energy. Energy is important to perform daily tasks as big as moving and as small as undergoing mitosis. All of this energy comes from the food we eat.
Metabolism is a complex process that works to break down the calories within food and convert them into energy we can use.
Natural Selection helps animals survive in their habitats and they have adaptations to help them survive better.
