Answer: Yes, many plant cells have both mitochondria and chloroplasts!
Hope this helped! :D
If ice did not float, the world would be a hot mess. Ice reflects lots of sunlight, so if it was at the bottom, our world would be significantly hotter. Additionally, plants grow at the bottom, so if they were trapped in ice, the water would run out of oxygen and everything would die. Bottom feeders would not exist, because they would be frozen. Also, the ice would just like on, because the water above prevents it from melting entirely, leading to all of our bodies of water eventually freezing.
Answer:
Carbondioxode is present in the atmosphere which is used by plants during the process of photosynthesis. From this process, plants make their food by using carbondioxode from the air for making glucose. The carbondioxide is released in the atmosphere by the animals during respiration process and the carbon concentration is stable.
Increase occurs in carbondioxide concentration due to human activities such as use of fuels in vehicles and industries.
Answer:
pinwheel
Explanation:
Orientation preference in the primary visual cortex is a prominent feature of higher mammals. The neurons are arranged in the fix orientation in a primary visual cortex.
The orientation map has analysed that there are pinwheel like orientation are arranged in the ordered fashion. Orientation preference of straight-line stimuli across the primary visual cortex is arranged in pinwheel pattern.
Thus, the correct answer is option (b).
The barrier that you need to get through is the cell wall.
