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.
Answer:
True
Explanation:
ion: an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
Answer:
1.0 L
Explanation:
Given that:-
Mass of
= 
Molar mass of
= 64.099 g/mol
The formula for the calculation of moles is shown below:

Thus,


According to the given reaction:-

1 mole of
on reaction forms 1 mole of 
0.0396 mole of
on reaction forms 0.0396 mole of 
Moles of
= 0.0396 moles
Considering ideal gas equation as:-

where,
P = pressure of the gas = 742 mmHg
V = Volume of the gas = ?
T = Temperature of the gas = ![26^oC=[26+273]K=299K](https://tex.z-dn.net/?f=26%5EoC%3D%5B26%2B273%5DK%3D299K)
R = Gas constant = 
n = number of moles = 0.0396 moles
Putting values in above equation, we get:

<u>1.0 L of acetylene can be produced from 2.54 g
.</u>
Covalent bonds would be formed when a non-metal bonds with another non-metal
