Anna11 [10]

Answer:

Plant A listens to classical music for three hours each day

Explanation:

  • Music affect plant growth of plants through the vibrations that it creates to the sound waves.Classical music causes more pressure to the sound waves causing vigorous vibrations  which is picked up by the plants speeding up the protoplasmic movement in the cells.
  • The vibrations causes movement of  the plant cells which speed up growth of the plants by stimulating the plants to produce more nutrients enabling them to germinate having more leaves,greater in size and other improved characteristics which means the plant's genetic chromosomes were changed.  
  • Also in the soil  is able to produce good fungi and bacteria encouraging better root development due to healthy vines resulting to vigorous growth and better fruit.
  • Moreover the plants are able to receive special attention and care from the farmer thus enhancing faster growth.

Besides producing sugar for itself, a plant also needs to absorb nitrogen to build proteins, salts to make concentration gradien
tino4ka555 [31]

Besides producing sugar for itself a plant also needs to absorb nitrogen to build proteins, salts to make concentration gradients and potassium to make enzymes.

<u>Explanation:</u>

Plant sugar is glucose and plants produce it by the process of photosynthesis making use of energy from sunlight, carbon dioxide absorbed from the atmosphere and the presence of chlorophyll in its parts. Plants also require components other than this. Nitrogen is essential to make proteins and it cannot be directly absorbed from the atmosphere but has to be absorbed from the soil.

Potassium is an essential component which is absorbed from the soil. It facilitates the activation of enzymes which play a crucial role in plant metabolism.  When plants lack potassium they won’t have enough energy for proper growth and will have poorly formed roots and weak stems.

What is a biological example of Juxtacrine Signaling?
kodGreya [7K]

Answer:

An example of juxtacrine signaling is exemplified by the activity of some cell adhesion or ECM proteins, such as laminin, that do not just allow a cell to move over them, but act as signals to promote increased motility

Would an organism be able to live in a biome they don’t usually live in ?
Zielflug [23.3K]

Answer:

Usually, no.

Explanation:

Normally, certain organisms and populations have already adapted to their respective environments. If you take that organism out of its preferred habitat and put it in an environment completely new to it, it would most likely die; in addition, the same biomes on different parts of the world even have slightly different organisms and amount of vegetation covering it.

The variability in marine salinity between habitats does not impact the fish living there.
nikitadnepr [17]
Well, there are two kinds of organisms: osmoregulators, that can regulate the level of salt and the salinity does not affect them (an example is salmon: for salmon this sentence is true. Generally, for most fish this sentence is true)

However, for some species, such shark - osmoconformers - this is false: they are affected by the salinity. in general I would conclude that This is false: the marine salinity DOES affect the fish (and other organisms) living there.
