An experiment to test the best conditions for bacteria to grow is the material that the bacteria feed upon. <u>Option D.</u>

<u />

Antibacterial hand soap with different concentrations. Dependent variable bacterial growth as measured by the diameter of the zone of inhibition. Exposing Petri dishes to different temperatures can skew the level of bacterial growth they inhabit. Plant height is the dependent variable that responds to changes in the independent variable.

Sunlight is the controlling variable because each plant is exposed to the same amount of sunlight. It is the dependent variable because it measures the amount of plant growth. The dependent variable depends on the independent variable. How much plants grow depends on how much sun they receive. A continuous increase in temperature from a minimum value increases the rate of bacterial growth because the rate of metabolic reactions increases with increasing temperature.

Answer:

C

Explanation:

This is placing a cell in hyper tonic solution.Therefore, the water potential of the cells is higher than the environment. Hence it lose water to the environment which has a  lower water potential, but higher solute potential.

Therefore the loss of fluid by the cell leads to shrinking of the cytosol and it containing organelles. Later the cells collapse.

<u>Spanish</u>

Esto es colocar las células en una solución hipertónica. Por lo tanto, el potencial hídrico de las células es mayor que el del medio ambiente. Por lo tanto, perder agua al medio ambiente reducirá el potencial hídrico, pero aumentará el potencial de soluto.

Por lo tanto, la pérdida de líquido por parte de la célula conduce a la contracción del citosol y que contiene orgánulos.

Does the study of disease require Science? If yes, why?
Stella [2.4K]
First of all science is needed to study most things including diseases and this is so since the study of diseases would require a research organism of course and this is any creature that scientist would use to study life and so without science this would not be possible as science allows for the study of animals and humans which are likely to be vectors and diseases requires epidemiology which are scientific disciplines similar to biology to better understand the disease processes and so science is definitely needed.

Answer:

The correct answer is option D. True tissues.

Explanation:

The cell that made sponge does not form the tissue however sponge have cells that play important role and specific for specific function but does not have true tissues.

In other animal phyla cells form tissue or organ or organ systems and called as true tissues.

Thus, the correct answer is option D. True tissues.
