Answer:
popcorn kernels aren't living things
Explanation:
characteristics they have that show proof they are living organisms:
• movement when exposed to heat
• irritability/sensitivity since they react to change of temperature
• growth since when they are exposed to high temperatures they grow and become bigger
We can determine if they are living or not by:
• seeing if they respire
• seeing if they need nourishment
• seeing if they can excrete
• seeing if they can reproduce
In conclusion they aren't living things
Answer:
D, organisms that survive long enough to reproduce.
Explanation:
C and D are the best answers. Adaptations and skills other than speed and strength contribute to an organism's survival too, so that means it isn't C. Natural Selection is about how an organism must have useful traits to survive to reproductive stage and successfully reproduce, so it would definitely be D.
Please Mark Brainliest! I need nine to level up.
Explanation:
The amount of blood that leaves the left ventricle of the heart with each contraction is called Stroke volume.
A person has a stroke volume of 80 ml/beat. It means that it is 80 milliliters per beat.
We need to find how many liters would that be.
We know that, 1 litre = 1000 milliliters
1 mL = 0.001 L
To convert 80 mL to litres, we can do it as follows :
80 mL = (80 × 0.001) LL
= 0.08 L
Hence, he stroke volume of a person is 0.08 L/beat.
