Answer: The correct answer is -
B) The presence of at least one carbon-based sugar.
Explanation:
RNA (ribonucleic acid) and DNA (deoxyribonucleic acid) are the two types of nucleic acids that are composed of nucleotide (monomer of nucleic acid).
A nucleotide has three parts, which are pentose sugar (5 carbon sugar), nitrogenous base, and phosphate group.
Starch is a complex carbohydrate as it is composed of several units of simple sugar such as glucose.
Thus, the presence of at least one carbon-based sugar is common in DNA, RNA, and Starch.
The answer is C. If you search it up it will show that the answer is c.
Answer:
Oxygen
Explanation:
Plants take in water, Carbon Dioxide and light to make oxygen for humans and animals to breath.
Answer:
The <u>PCO₂</u> -carbon dioxide partial pressure- in the alveoli is 40 mm Hg and that of the blood entering the pulmonary capillaries is <u>45 mmHg</u>. This causes <u>carbon dioxide</u> to diffuse down its partial pressure gradient from the blood into the alveoli.
Explanation:
Gas exchange is a physiological process that involves the entry of oxygen into the body and tissues and the exit of carbon dioxide, a product of metabolic reactions.
At the pulmonary level, gas exchange occurs between the alveoli and the alveolar capillary, and the diffusion of gases across the alveolar-capillary barrier is dependent on a pressure gradient due to the partial pressure of gases.
In the case of CO₂ the diffusion goes from where the partial pressure is higher to where it is lower, i.e. <u>from the alveolar capillary, where the PCO₂ is 45 mmHg, to the pulmonary alveolus, where the PCO₂ is 40 mmHg</u>.
