Pioneer Species are hardly species which are the first to colonize previously disrupted or damaged ecosystem, beginning a chain of ecological succession that ultimately leads to a more biodiverse steady state ecosystem and the best example to it is the flower called Centaurea Maculosa
Answer: A, B, and D
Explanation:
1. A - mitosis produces offspring that are genetically identical to the parents so A can't be true.
2. B - meiosis produces offspring that are haploid (they only contain one copy of the chromsomes and not 2 like the parent gametes) so B isn't true.
3. D - all of the above
The mouse, every other animal is on it's own as soon as it hatches.
The respiratory system, functionally, can be separated in two zones namely the conducting zone (nose to bronchioles) form a path for conduction of the inhaled gases and respiratory zone (alveolar duct to alveoli) where the gas exchange takes place. Anatomically, respiratory tract is divided into upper (organ outside thorax-nose,pharynx and larynx) and lower respiratory tract (organ within thorax-trachea, bronchi, bronchioles, alveolar duct and alveoli). Airway closure is a normal phenomenon in the body, with reopening of airways during the succeeding inspiration.
The appropriate choice would be the supraglottic portion of the laryngeal vestibule. It is the portion of the cavity of the larynx above the vocal cords. It is wide and triangular in shape, it is inlet to another cavity in the lateral wall of larynx, the laryngeal ventricle.
