Answer:
More Carbon dioxide is removed from the blood and exhaled in the breath
Explanation:
During exercise there is an increase in physical activity and muscle cells respire more than they do when the body is at rest. The heart rate increases during exercise. The rate and depth of breathing increases - this makes sure that more oxygen is absorbed into the blood, and more carbon dioxide is removed from it. So, when you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide.
Answer:KEYSTONE SPECIES
Explanation:
the ecosystem would be extremely different without the key stone specie or cease to exist complete .
Basically a keystone specie is a specie that helps define an ecosystem and if the specie was to die or cease to exist no other specie can take its place and the ecosystem will have to change radically and it'll be forced to introduce a whole a new habitat because the keystone specie has a huge influence on the food web
EXAMPLE :
A keystone specie could be any specie ranging from plants to fungi
Number 5 is A plants. Fossils of ancient reptiles have been called Cynognathus and Mesosaurus have been found on South America and Africa.
The answer is homo sapiens. It is believed mating apparently
took place in the Middle East, shortly after modern humans had left Africa.
Research has shown that Neanderthal DNA
is 99.7 percent identical to modern human DNA. All modern ethnic groups, other
than Africans, carry traces of Neanderthal DNA in their genomes, which
therefore supports this revelation.
First, we have to know the definition of the following vocabulary terms:
Abiotic = non-living
Biotic = living
Then, it's just a matter of seeing which answer choice has both a living organism and a non-living part of the ecosystem.
Correct Answer:
Algae and sunlight
- Algae is actually a living organism called a protist, which uses sunlight in a process called photosynthesis to create its own "energy" (just like plants).
- Sunlight is nonliving, but it is still an important part of the ecosystem especially for photosynthetic organisms like algae.
