The two correct options are Poison dart frog and Boa constrictor. Both these organisms are pure carnivores which are also known as pure meat eaters in the food web. Carnivores are organisms in the food chain that only meat-eaters and never take any type of vegetation in their diet.
Explanation:
- A Poison dart frog purely survives on meat (meat- eater).
- Long sticky tongues are used to catch their prey such as ants, flies, insects.
- Since they produce high toxin levels, it has very few predators in the wild.
- Boa constrictor is also an organism that eats only meat.
- While they are young they eat prey like rats, squirrels and mice.
- The type of attack used by a boa constrictor is an ambush attack type. It attacks its preys using the surprise factor.
It is called a cycle because it is repetitive, therefore making it a cycle (or almost never ending)
Answer:
32. Opcion E
Explanation:
ZO₂ podemos entenderlo como dióxido de Z
1 mol de ZO₂ contiene 1 mol de Z y 2 moles de O₂ por lo que si la masa molar es de 64 g/mol, podemos plantear lo siguiente
Masa de Z + 2 masa de O = 64 g/mol
Sabemos que la masa del oxígeno es 16 g/mol
x + 2. 16 g/mol = 64 g/mol
x = 64 - 32 → 32 g/mol
La masa atómica coincide con la masa molar, por lo tanto la masa atomica de Z es 32.
