Answer:
The correct answer will be option-B.
Explanation:
The plant tissues are composed of three types of cells: parenchyma, collenchyma and sclerenchyma.
The parenchyma and collenchyma remain alive at their maturity but sclerenchyma loses their protoplasm and become dead. These cells deposit lignin in their secondary walls and form hard tissues of the plant-like hard shell of a coconut. Sclerenchyma provides mechanical strength to the plant.
Thus, Option-B is the correct answer.
Answer:
Hey mate......
Explanation:
This is ur answer.....
1A) There are 2 ways:-
<em><u>•</u></em><em><u> </u></em><em><u>Anaerobic Respiration.</u></em>
<em>The anaerobic respiration process takes place in the absence of oxygen. </em>
<em><u>•</u></em><em><u> </u></em><em><u>Aerobic Respiration</u>. </em>
<em>In aerobic respiration, breakdown of pyruvate takes place in the presence of oxygen to give rise to 3 molecules of carbon dioxide and water.</em>
2A) <em>Oxygen is transported from lungs to body cells in the form of oxyhemoglobin . the main 2 gases exchanged are 02 & C02 . 02 is absorbed by blood capillaries from lungs alveoli by diffusion while C02 is absorbed by blood alveoli from blood capillaries by diffusion.</em>

Answer: Transcription
Explanation:
Transcription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis. ... The pre-messenger RNA is then "edited" to produce the desired mRNA molecule in a process called RNA splicing.
A- non-native species can have positive and negative affects
it is caused by relaxation of smooth muscle cells that are in the vessel walls which in the large arteries.
