<span>A spider is small enough that its weight can be supported by surface tension, the relatively weak forces that hold water molecules together. </span>Water molecules "bond"<span> to other water molecules around them in all directions, so they tend to stick more strongly to their neighbors, forming a film-like layer across the surface</span>

Mariana [72]

Answer:

C) Bacteria congregated in these areas because these areas had the most oxygen being released.

Explanation:

Below is the full question:

Theodor W. Engelmann illuminated a filament of algae with light that passed through a prism, thus exposing different segments of algae to different wavelengths of light. He added aerobic bacteria and then noted in which areas the bacteria congregated. He noted that the largest groups were found in the areas illuminated by the red and blue light.

What did Engelmann conclude about the congregation of bacteria in the red and blue areas?

A) Bacteria released excess carbon dioxide in these areas.

B) Bacteria congregated in these areas due to an increase in the temperature of the red and blue light.

C) Bacteria congregated in these areas because these areas had the most oxygen being released.

D) Bacteria are attracted to red and blue light and thus these wavelengths are more reactive than other wavelengths.

E) Bacteria congregated in these areas due to an increase in the temperature caused by an increase in photosynthesis.

The most efficient region of white light for photosynthesis has been found to be the blue and red region of the white light. Hence, these two regions must have had the most oxygen being released because they are the regions with the highest rates of photosynthesis.

<em>Aerobic bacteria thrived better in the regions illuminated by red and blue light because these regions had the highest oxygen production as a result of having the highest rates of photosynthesis.</em>

<em>The correct option is C.</em>

Which box depicts the tissue level of organization?
Effectus [21]
<span>Levels of OrganizationIn unicellular (single-celled) organisms, the single cell performs all life functions. It functions independently. However, multicellular (many celled) organisms have various levels of organization within them. Individual cells may perform specific functions and also work together for the good of the entire organism. The cells become dependent on one another.Multicellular organisms have the following 5 levels of organization ranging from simplest to most complex:<span><span>LEVEL 1 - Cells<span><span>Are the basic unit of structure and function in living things.
</span>May serve a specific function within the organismExamples- blood cells, nerve cells, bone cells, etc.</span></span><span>LEVEL 2 - Tissues<span>Made up of cells that are similar in structure and function and which work together to perform a specific activity
Examples - blood, nervous, bone, etc. Humans have 4 basic tissues: connective, epithelial, muscle, and nerve.</span></span><span>LEVEL 3 - OrgansMade up of tissues that work together to perform a specific activityExamples - heart, brain, skin, etc.</span><span>LEVEL4 - Organ Systems 
<span>Groups of two or more tissues that work together to perform a specific function for the organism.
Examples - circulatory system, nervous system, skeletal system, etc. 
The Human body has 11 organ systems - circulatory, digestive, endocrine, excretory (urinary), immune(lymphatic), integumentary, muscular, nervous, reproductive, respiratory, and skeletal.</span></span><span>
LEVEL 5 - Organisms 
<span>
Entire living things that can carry out all basic life processes. Meaning they can take in materials, release energy from food, release wastes, grow, respond to the environment, and reproduce.
<span>Usually made up of organ systems, but an organism may be made up of only one cell such as bacteria or protist.
</span>Examples - bacteria, amoeba, mushroom, sunflower, human</span></span></span></span>

butalik [34]

ANSWER: POPULATION ECOLOGY

EXPLANATION:

The scientific field that deals with populations (i.e all individuals of a single species inhabiting a community) and how they interact with their extrinsic environment, is referred to as POPULATION ECOLOGY.

Thus, it's categorized under population ecology, because the research depicts how the number of individuals (beetles) in a population changes in time and the gross impact on their number decrease and loss of all the individuals (extinction) over a period of time.
