Option B, "They need more oxygen to function, so gas exchange needs to increase. "
Answer:Kristen is running a half marathon. By her tenth minute of running, her breathing rate has increased from her resting rate.
Which statement best describes how her tissues are responding to her running?
They need more oxygen to function, so gas exchange needs to decrease.
They need more oxygen to function, so gas exchange needs to increase.**
They need more carbon dioxide to function, so gas exchange needs to increase.
They need more carbon dioxide to function, so gas exchange needs to decrease.
Explanation:
took test
A). They are autotrophs
Answer is C ) chloroplasts.
Chloroplasts are oval shaped, double membraned cell organelles present in green plant cells and in algae. Chloroplasts contains a green color pigment called chlorophyll. Chlorophyll has ability to capture solar energy and store this energy in the form of ATP (adenosine triphosphate). with the help of this energy and water, green plants reduced carbon dioxide into sugar (a chemical compound) as food.
When the filament is tall, the anther is more exposed to different pollination agents. There are more chances that pollen grains stick on the animals' and insects' bodies or get blown by winds.
------------------------------
Flowers are reproductive structures in charge of the plant's sexual reproduction.
There are feminine and masculine reproductive structures.
The masculine structures include stamens, which are composed of anthers and filaments.
Mature pollen grains are driven to the stigma of the same flower or other flowers for the fertilization process.
Different agents are in charge of this transport: animals, wind, insects, water streams.
When filaments are tall, the anthers are more exposed and not protected by the flower.
So these anthers are more accessible for different agents.

Make connections: How might having the anther atop a tall filament make it more likely that plants will be pollinated? It gets the pollen grains up higher. That makes it more likely that a visiting insect will pick them up.4. ... When the pollen forms on the stamen, the pistils are not ready to receive it.
