Answer:
a. undergo complete metamorphosis and have segmented bodies
c. undergo complete metamorphosis and have an exoskeleton
Explanation:
Insects are the members of the phylum Arthropoda. They have jointed legs. Their body is segmented externally into the head, thorax and abdomen. Their body is covered by an exoskeleton. Exoskeleton formed from thick non-living cuticle which is made of chitin. In them, fertilization is internal. They are mostly oviparous. Development is direct or may be indirect. In the case of indirect development, there is complete metamorphosis.
Biodiversity impacts the environment and its stability because one organism depends on the other to survive, it is call the food change. The more biodiversity the healthier the environment.
Shelter: an ecosystem will only provide a certain amount of shelter for its organisms.
Competition: it will be determine by the amount of food available in that ecosystem.
Food: the amount of food available will be a factor on the population an ecosystem will be able to maintain.
Predators: there have to be a balance between predators and prey or food available.
Disease: It will affect the number and health of all the organisms living in the ecosystem.
Answer:
The evolution of the organisms can be explained on the different evidences like biochemical evidence, molecular evidence, morphological evidence and fossil evidence.
The fossil evidence indicates the direct evidence of the evolution. The feather present in the dinosaurs is used as the insulation that provide the heat to the birds. Later on the crowding on the land forms leads to the adaptation of the flight in the dinosaurs.
Answer:
En la fotosíntesis, la energía de la luz se utiliza para convertir el dióxido de carbono y el agua en glucosa y oxígeno. Para 6 moléculas de dióxido de carbono y 6 de agua, se producen 1 molécula de glucosa y 6 moléculas de oxígeno.
Explanation:
A = Phosphate group
B = Deoxyribose sugar
C = Nitrogenous base
