Plants use different structures and processes to create offspring. Sphagnum spp. is a type of moss typically found in peat bogs. As Sphagnum spp. dies and decays, it creates peat moss. Peat moss is a type of organic matter popular in gardening due to its ability to absorb and hold moisture. Adding peat moss to soil can help create better growing conditions for plants. Which structure is part of Sphagnum spp. reproduction, but not part of fern reproduction?A. sporophyteB. gametophyte C. protonema D. sori

Some herbicides prevent sucrose uptake by plant cells. Upon applying the herbicide to an isolated plant cell, it was detected that the pH of the Solution surrounding the cell decreased over time. How do you think this herbicide specifically affects plant (be specific as to why the plant cannot uptake sucrose!)

Answers

Answer:

Herbicide essentially replaces sugar with itself during uptake by plants.

Explanation:

Noting that the pH is decreased around the plant cells indicate that there is an acidic environment that exists, It also indicates that the cell wall  had been perforated and the contents are being expelled or at the very least leaking.

The ability for the plant to break down and use sugar is vital for its survival. Most herbicides are in the form of glycophosphates and it moves along with the sugar in the plant that have been treated with herbicides through the transport vesicles, the xylem and phloem.

This causes an imbalance in the available sugars that are able to be taken up by the plant since much of it is replaced by the herbicide.

Enter your answer

Answers

Answer:

Temporary or Induced Magnets.

Explanation:

  • Temporary magnets: These magnets are made of soft iron that has temporary magnetic properties. These magnets behave as permanent magnets when introduced to a magnetic field but lose magnetism when moved away from the magnetic source.
  • Temporary magnets are usually used in radio, electric motors, phones.
  • They are extensively used as electromagnets to produce electricity.
  • The demagnetizing property of electromagnets by altering the intensity of electric current helps in a lot of practical applications based on controlled situations.

Processes that increase the density of seawater include evaporation and

Answers

Processes that increase the density of seawater include evaporation and sea ice formation. The density of seawater primarily depends on two factors, temperature and its salinity. When temperature is decreased and salinity is increased, the density increases. Sea ice formation lowers the seawater's temperature, while evaporation increases the salinity.
