Answer:
What sends oxygenated blood back to the heart from the lungs?
Oxygen-rich blood flows from the lungs back into the left atrium (LA), or the left upper chamber of the heart, through four pulmonary veins. Oxygen-rich blood then flows through the mitral valve (MV) into the left ventricle (LV), or the left lower chamber.
Explanation:
So basically you have to like multiply and stuff so you would freaking get like 250 or something.
Answer:
<em>between </em><em>an </em><em>animal</em><em> </em><em>cell </em><em>and </em><em>a </em><em>plant </em><em>cell </em><em>there </em><em>are </em><em>some </em><em>parts </em><em>that</em><em> </em><em>are </em><em>similar</em><em> </em><em>and </em><em>carry </em><em>out </em><em>the </em><em>same </em><em>function </em><em>like:</em>
<em>both </em><em>have </em><em>a </em><em>cell </em><em>membrane</em><em> </em><em>which </em><em>selects </em><em>what </em><em>goes </em><em>in </em><em>the </em><em>cell.</em>
<em>both </em><em>have </em><em>cytoplasm</em><em> </em><em>which </em><em>holds </em><em>the </em><em>protoplasm(</em><em>the </em><em>living</em><em> </em><em>part </em><em>of </em><em>the </em><em>cell)</em>
<em>both </em><em>have </em><em>a </em><em>nucleus</em><em> </em><em>which </em><em>carries </em><em>out </em><em>all </em><em>cell </em><em>activities</em><em> </em><em>and </em><em>holds </em><em>threads </em><em>of </em><em>DNA </em><em>called </em><em>chromosomes</em>
<em>both </em><em>have </em><em>a </em><em>mitochondria</em><em> </em><em>which </em><em>is </em><em>the </em><em>power </em><em>house</em><em> </em><em>of </em><em>the </em><em>cell</em>

The correct answer is: B) flesh of another animal
The shape of teeth is tightly connected with the food that animal eats.Examples:
• Herbivores (plant eaters) have flat teeth specialized for the grass chewing.
• Carnivores (flesh eaters) have long and sharp teeth for meat cutting.
• Omnivores (eat meat and plants) such as humans have various types of teeth with different functions.
There are four main types of teeth: incisors (at the front, sharp for cutting), canines ( to grip and tear food), premolars (flat surface for food crushing), molars (the biggest with flat biting surface, to chew).
