Answer:
↓
Explanation:
I can't really read what you have typed, but the subscripts are the little numbers such as this 2 in H₂O. So using the blue pen, I'm assuming you would circle the little numbers. The coefficients are the numbers in front of the elements so from what I can read, in 2HCl the 2 would be circled in the orange. So in a simple way the subscripts are the tiny numbers that are at the bottom (usually after elements), and the coefficients are normal numbers in front of the whole element.
Hopefully that makes sense! :)
Answer:
True.
Explanation:
The heart of the mammals is divided in half by the right atrium and ventricle (AD, RV) and the atrium and left ventricle (LA, LV). The atria communicate through a small fissure within the ventricle, and the ventricles communicate through the pulmonary trunks. In the atrium there are two vena cavae and a pulmonary artery with two outlets. In the ventricle there is an artery with only one outlet, the aorta and a bicuspid valve. This entire structure supplies oxygenated blood to the organs through one channel, while the other directs blood to the lungs for re-oxygenation.
On the other hand, the heart of reptiles has three cavities: two atria (one right and one left) and one ventricle. The heart of crocodilian reptiles has four cavities: two atria and two ventricles (such as birds and mammals). However, even in crocodilians there is a mixture of blood types (venous and arterial) that pass through the heart, although to a lesser extent than in amphibians. Thus we can consider the circulation of reptiles double and incomplete. Because of this, the animals in this group are pecilodermic, that is, they adapt the body temperature to the ambient temperature.

Explanation:
Streptobacilli are linked together in chains, the bacterium is gram positive and the generally rod-shape. The genus could be aerobic ( required oxygen for their growth), falcultative anaerobe (in the absence of oxygen, they can switch to fermentation).
