Answer:
Hydrogen bonding between water molecules allows water to be <u>cohesive.</u> This property of water allows it to rise from a plant's roots to its highest branches.
Explanation:
Cohesion is that force of attraction between molecules that holds the particles of a substance together with others of the same type. It is said that a liquid has more or less cohesion, depending on whether its molecules are more or less attracted to each other. In water, the cohesion force is high because of the hydrogen bonds that hold the water molecules tightly bound together, forming a compact structure. For example, in plants, it is essential that the water column be kept continuous, so that the tension of the xylem (conductive plant tissue) is transmitted to the root. The water column is held together thanks to the powerful cohesion forces that attract water molecules together.
Answer:
No, they don't.
Explanation:
Trees need leaves for photosynthesis because leaves contain chlorophyll. As the article states, the food-making process stops after these trees lose their leaves. Some trees keep their leaves all year long.
The brain is divided into lobes that carry out different kinds of functions. There are 5 lobes in the brain:
1. Frontal lobe: Concentration, planning, problem solving, etc are the function performed by this region of the human brain.
2. Parietal lobe: Touch, pressure, taste and body awareness is processed by this lobe.
3. Temporal lobe: Long-term memory, hearing, emotions are processed in this lobe.
4. Occipital lobe: Sight is processed in this lobe.
5. Cerebellum: Coordination and balance, fine motor control are performed by this part of the brain.
The modern neuroscience has also confirmed the presence of brain waves like the alpha, beta, theta and gamma rhythm that sweep across the different lobes and regions of the brain. These waves are known to result from the collective activity of neurons in each of the regions. The brain waves are studied to check the activity of the regions that are coordinating together to carry out a particular type of task.
Answer:
Biological species contest.
Explanation:
Different species concept are introduced to describe the exact definition and classification of species. Some species concept are biological species contest, morphological species concept and ecological species contest.
According to biological species contest, the group of individual that can breed among themselves and not with the other group. Here, the Drosophila species has been classified by the biologist depending on their mating ability to their group of individual only.
Thus, the answer is biological species contest.
the biome that is found at the biomes is called tundra
