Answer:
False.
Explanation:
Classification of organism is important to classify them in similar and different groups. Organisms can be classified on the basis of the development of the mouth or the anus first.
The organism in which mouth develops first by the opening of gastrula are called protostome not deuterostomes. Deuterostome develop anus first from the opening of gastrula.
Thus, the correct answer is option (b).
Climate regulation, nutrient cycling, and other ecosystem services are economically valuable and essential for life on Earth.
Oxygen
During aeroobic respiration oxigen reacts with sugar or glucose, producing carbon dioxide, water, and energy.
During anaerobic respiration when there is not enough oxygen, cells break down glucose into lactic acid and energy.
Answer:
English:
RNA and DNA are polymers made up of long chains of nucleotides . A nucleotide is made up of a sugar molecule (ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).
Spanish:
El ARN y el ADN son polímeros formados por largas cadenas de nucleótidos. Un nucleótido está formado por una molécula de azúcar (ribosa en el ARN o desoxirribosa en el ADN) unido a un grupo fosfato y una base nitrogenada. Las bases utilizadas en el ADN son la adenina (A), citosina (C), guanina (G) y timina (T).
Answer:
I believe the answer is C from my knowledge.
