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>

Orlov [11]

Answer:

Mutation.

Explanation:

All adaptations begin as a genetic mutation because these adaptations passed from one generation to another generation through genes of that organisms. Organisms that are adapted to their environments and survive more better, it will produce more offspring in which that genetic characteristics are transmitted from the parents so we can say that genetic mutation is responsible for adaptations.

What theory dramatically improved geologist's ability to predict where certain ore deposits were formed? Select one:
mrs_skeptik [129]

Plate tectonics is referred to a geology theory, which explains the movement of earth’s lithosphere.  This theory suggests that the earth’s lithosphere is made up of many plates, and these plates move on each other causing collision of the plates or sometimes separation of the landmasses.  

Sometimes, the movements of the plate occur in such a way that the surface of the earth is buried underground. Even in normal circumstance, some of the surface materials buried underground. So, by studying the type of things existed on the surface in past, one can predict the abundance of a specific substance underground.  

Hence, the correct answer is option b. – Plate tectonics.

In an ecosystem, why can only one species fill an ecological niche? (Site 1)
Anastaziya [24]

Answer:

Only one species can fill an ecological niche because each niche is destined exclusively for each species, since its structure, physiology and behavior determine it.

Explanation:

An ecological niche is the way in which each species relates to its environment, to other species and takes advantage of the resources available for its development, being an exclusive and individual characteristic of that species.

The ecological niche is a concept that many consider abstract, since it is unique for a species. Each species has a physical structure, functioning and behavior that differentiates it from the others, which leads it to occupy a certain place within an ecosystem, which would be its ecological niche.

How does the movement of materials across the cell membrane relate to an<br> organism’s survival?
ioda

I believe it relates because as we know the cell membrane is permeable meaning that allows oxygen, carbohydrates, food to enter the cell but it doesn't allow the entrance of large molecules that harm the cells.

After all the movement around it, matters because for example without food the mitochondria won't be able to create the energy and then with that energy, the nucleus to use it to complete the main the activities of the cell.

Hopefully this what you meant when you asked the question. Have a nice day/evening
