Answer:
Respiratory
Explanation:
Red blood cells pick up oxygen in the lungs.
Answer:
A test tube would be used
Explanation:
The test tube refers to a laboratory device that is made of graduated glass for which cylinder used to measure small quantities of liquids that is from 5 mL to 2 L. The most suitable type of specimen must be chosen for measuring the liquid volume, in this situation that is a 15 mL. The specimen is shutdown to lower and has a support base.
Therefore the correct answer is a test tube.
Based on the traditional definition of species, bacterial species cannot be defined readily, due to the fact that they do not mate.
<h3>Why does the typical definition of a species not fit bacterial species?</h3>
The definition of species is that a species is one with distinct characteristics that produce viable offspring when mated with another organism in the same species.
This definition of a species does not fit bacterial species because bacterial species do not mate or reproduce se×ually.
Bacterial species reproduce by other means that do not involve mating such as by binary fission.
Therefore, based on the traditional definition of species, bacterial species cannot be defined readily, due to the fact that they do not mate.

Answer:
B. Convection
Explanation:
most of heat energy transferred in the troposphere is done by convection. Convection does not only mean thunderstorm clouds but means any mixing of air. Air is always on the move (rising, sinking and advecting). The air mixes as it moves into the surrounding air.
B. Convection Currents
If you want it explained, read on.
Lets go through the answers here. A. Conductive enegry cant be correct since conduction is when heat is transfered through touching objects. B. Convection currents are when heat is trasfered through a current, so we will come back to this one. C, well, its not radioective at all. D radient heat is when heat trasfers from the sun. Now, back to b. The question describes a circular current between the poles and the Equator. Heat tranfer through convection is through currents.
