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:
a = 9
Explanation:
5(a + 4) - 6a + 1 = 12
5a + 20 - 6a + 1 = 12
5a - 6a + 20 + 1 = 12
-1a + 21 = 12
-21 -21
--------------------------------
-1a = -9
/-1 /-1
---------------------------------
a = 9
Answer:
Another evidence of evolution is the convergence of form in organisms that share similar environments.
Answer:
The correct answer is - A. Growth 1, Synthesis, Growth 2.
Explanation:
The cell cycle has three important phases Interphase, M -phase and cytokinesis. Interphase is the laongest phase of eukaryotic cell cycle. This phase shows no observational change in the cell, however, it collects nutrients, generates protein and replicates DNA and prepare the cell for the M- phase.
Interphase has 3 phases G1, S, and G2 phase. G1 phase is the phase that collects nutrients and increase the size of the cell for the cell division. S phase or synthesis phase is the phase takes maximum time in cell divivon and acompanied by protein generation, duplication of the genetic material. G2 phase is preparatory phase that prepeare the cell before the cell enter in the M - phase.
