When making yogurt, bacteria and milk are mixed together and set in a warm area. The container is sealed and no gasses are allow
Ivenika [448]

Answer:

When making yogurt the tart flavor get in the end is more likely because the bacteria have carried out a type of respiration named lactic acid fermentation (option C).

Explanation:

The process of obtaining yogurt from whole milk involves the association of the bacterial species Streptococcus and Lactobacillus. In order to carry out the lactic acid fermentation that produces yogurt, the bacteria act in a different way:

  1. Streptococcus is in charge of removing the oxygen from the milk product.
  2. Lactobacillus promotes the conversion of lactose sugar into lactic acid.

This fermentation process  leads to the conversion of milk into a coagulated and tart flavor product.

Other options are not correct because:

<em>     A.  </em><u><em>Photosynthesis </em></u><em>: is the process that occurs in plants to obtain chemical energy from sunlight.</em>

<em>      B.  </em><u><em>Alcoholic fermentation</em></u><em>:  in this chemical process alcohol is obtained from the fermentation of a sugar.</em>

<em>      D.  </em><u><em>Aerobic cellular respiration</em></u><em>: does not involve fermentation, but the series of processes that convert glucose into energy.</em>

A student prepared a slide of pollen grains from a flower. First the pollen was viewed through the low-power objective lens and
bearhunter [10]

Answer:

(2) low power: 100 small pollen grains

high power: 25 large pollen grains

Explanation:

Compound light microscopes are devices used to greatly magnify objects. They have several objective lenses, a low-power lens magnifies 10 times (10X) the objects, and the high-power lens magnifies them 40 times (40X).

For that reason, when observing the pollen grains with the high-power lens the student will see them bigger than with the low-power lens. However, the field of view (the visible area through a lens) is reduced when a higher power lens is used, so fewer pollen grains will be seen.

The answer therefore is the option of higher number of pollen grains of small size for the low-power lens, and lower number of pollen grains of larger size for the high-power lens.

If there was a fungicide that killed all fungi, make a prediction on how that would affect the ecosystem and eventually us human
marishachu [46]
Fungi is what decomposes things and puts nitrogen back into the ground. without the fungi plants would soon begin to run out of the nutrients they need. lack in vegetation would soon form. animals would then start to die of or migrate to different locations. so eventually you would begin to see less food and more wildlife in town because of the food shortage.
