Answer:
Option D, The work done by each force is negative
Explanation:
When both the forces are negative, then irrespective of which force is large or small, the net force will definitely negative. A negative force indicates reduction in kinetic energy of particle. Since mass is constant , it is the speed which reduces and produces negative work. Reduction in speed is contrasting to the statement give in the question. Hence, option D is not possible.
I would go with C
hope this helps
Plants found in cold environments have a higher amount of photosynthesis at low temperatures. Plants in warm environments, have a higher photosynthesis in high temperatures.
Photosynthesis is the process by which plants make their food from sunlight . This process is mostly dependent on sunlight so it varies from temperature and seasons. Greater light intensity leads to higher photosynthesis rates, as does increased carbon dioxide concentration.
Photosynthesis is generally higher during early summer and decline by autumn season . Temperature also plays an important role in photosynthesis as temperature increases the number of collisions increases, therefore the rate of photosynthesis also increases.

Vascular tissue transports materials.
Answer:
Most likely Bacterial vaginosis (BV)
Explanation:
BV is a sexually associated health problem in women caused by a change in the normal balance of bacteria in the vagina.
This happens when the population of the good bacteria called <em>lactobacillus</em> reduces, giving room for the multiplication and growth of bad bacteria. The good bacteria keep the vagina a bit acidic, thereby preventing the growth and multiplication of bad bacteria.
A woman that is sexually active is predisposed to having BV. White vaginal discharge that appears milky is one of the symptoms of BV. A vaginal pH 6 affirms it is mostly a BV, as the pH level that is greater than 4.5 would favors the population of bad bacteria.
The 30-year-old female who is sexually active and complains of a large amount of milk like vaginal discharge, with the vaginal pH at 6.0, is mostly likely having Bacteria vaginosis (BV)
