Red blood cells play a huge part in the human body
Red blood cells transport oxygen throughout the body
They are able to carry oxygen because of an important protein called haemoglobin.
Not only does haemoglobin carry oxygen, but it's also responsible for the red color of our blood.
If red blood cells didn't contain haemoglobin the cells wouldn't be able to do their job properly. If this happens we would slowly die
<span>The inferences I can make regarding the pH of a particular part of the digestive system is that it has a pH of 3. I know that 7 is neutral, and 8-14 is basic. I know that below 7 is acidic. The lower the number is from 7, the more acidic it is. I know that hydrochloric acid is quite acidic because I feel the burn from it when I get acid reflux attacks.
I think the relative size of carbon-based molecules are the size of a nickel, which I think is quite large. I think this because humans need carbon to live and a lot of foods contain carbon, so a lot of carbon molecules are broken down in the digestive tract.</span>
Answer:
Hypothesized causes for the declines include habitat destruction (the most obvious cause), climate change, pathogens, introduced exotic species, pollution, and increased UV radiation. These agents may act alone or in combination to contribute to the decline of amphibian populations.
Explanation:
I think this is the answer
Hope it helps you
Hypothesis- introduced evolution before Darwin, two big theories; use or disuse and acquired characteristics
The break down of carbon based molecules into smaller molecules
