Active transport makes it possible for cells to:______.
a. transport out secretory products and waste material against concentration gradients.
b. take up nutrients from the environment against concentrations gradients.
c. maintain nonequilibrium intracellular concentrations of ions such as Na , K , Ca2 , and H .
d. establish an electrical potential across the membrane.
e. All of the above are correct.
Answer:
e. All of the above are correct.
Explanation:
Active transport is a type of transport in living systems in which molecules/ions/substances are moved or transported against their concentration gradient i.e. from a region where the substance is LOW to a region which it is HIGH, across a membrane. Since molecules are transported across a memembrane against their concentration gradient, an energy input in form of ATP is needed to do so.
Active transport is used in living systems to transport out secretory products and waste material against concentration gradients, take up nutrients from the environment against concentrations gradients etc. Since ions are substance moved by active transport from a low region to high region, there is an imbalance in the intracellular concentration of ions, such as Na, K etc.
Since there is no equilibrium in the concentration of ions on opposite sides of the membrane, an electric potential is formed across the membrane i.e. one part of the membrane will be more positively charged than the other.

Which characteristic describes the whale but not its food source, the phytoplankton? The whale is heterotrophic. The whale has cell walls. The whale is unicellular. The whale is a prokaryote.
Answer:
A. The whale is heterotrophic.
Explanation:
The whale is an aquatic animal that is heterotrophic in nature. Heterotrophic means that this animal lacks the ability to manufacture its own food because it depends on plants and animals as a source of food energy. Since the Whale is dependent on phytoplankton for food, this means that it is not a producer of food and as such is heterotrophic.
Phytoplankton is a marine alga. Algaes are prokaryotes and this means that they are unicellular animals without a membrane-bound nucleus. The Cell wall is mostly a characteristic of plants. So the first option is a perfect description of the whale and not its food source which is the phytoplankton.
Answer:

Which best describes what happens if two waves meet and build on each other?
A. constructive interference
B. destructive interference
C. reflection
D. absorption
Answer:
constructive interference
Explanation:
when two waves build off of each other, they interfere with one another and construct. therefore, the answer is constructive interference.
When the path difference between subsequent crystal planes is equal to an integral number of electromagnetic radiation wavelengths, constructive interference occurs. Thus, option A is correct.
What is the constructive interference?Where the lines (which represent the peaks) cross over one another, constructive interference occurs. In other words, constructive interference occurs when two waves are in phase.
When two waves are entirely out of phase (a peak is located in the middle of two waves), destructive interference ensues.
Constructive interference is the phenomenon where the total amplitude of two waves is equal to the sum of the amplitudes of the separate waves when two waves are in phase and their maxima add.
Therefore, constructive interference best describes what happens if two waves meet and build on each other.

Describe how the water cycle moves water between the tree, the lake, and the sky in the picture below. Describe at least three of the water cycle processes you have learned about in the course. (10 points)
Answer:
The heat from the sun warms the water in the lake which evaporates and turns into water vapours. The water in the tree also rises into the atmosphere through a process, transpiration.
The water vapours rise into the atmosphere and forms clouds.
The water vapours in the clouds than condense into liquid water. Soon they'll get heavy and the water will fall down as rain, sleet, or snow.
Some of the rainwater sinks into the ground and is taken in by the roots of trees and plants.
This process keeps going on and on, and the water keeps shifting between the lake, tree and the sky.

Which of the following best expresses the concept of natural selection?
A) differential reproductive success based on inherited traits
B) inheritance of acquired characteristics
C) change in response to need
D) a process of constant improvement, leading eventually to perfection
E) survival of the fastest
Answer:
The correct answer is - option A. differential reproductive success based on inherited traits
Explanation:
Natural selection is the differential reproductive and survival of particular population due to the difference of shared characteristics that are inherited in a specific environment. In other words natural selection is differential reproductive success based on inherited traits.
The term differential reproductive success is suggests that comparing and analyzing successful reproduction rates between groups statistically which means how many individuals of the population left behind due to not inheriting traits require for survival.
Thus, the correct answer is - option A. differential reproductive success based on inherited traits
Due to genetic changes and the environmental conditions when the organism adapts itself to the current situation for survival is called natural selection.
Natural selection means that the organism that survived over another have better traits and characteristics for adaptation.
The correct answer is:
Option A. differential reproductive success based on inherited traits.
This can be explained as:
A particular type of trait carried by an organism that is better for adapting to survival than the other organism carrying less favorable trait will have a better chance of survival and their reproductive success will be much higher.Based on the inherited characteristics the natural selection will be based on reproductive success.Differential reproductive success is an analysis in which comparison is done among the organism that survived and those that did not.Comparing their traits and characters can give an idea about the factor affecting the selection.Therefore, differential reproductive success based on inherited traits best expresses natural selection.

Explanation:
The factories mostly need large quantities of water to carry out their production precesses, however, as well as they need natural recources for their operation, they also dispose of them and a large part of the environmental contamination is due to the release of substances emitted by these. It´s very easy for toxic waste to contaminate rivers, lakes and aceans. Groundwater on the other hand is more complicated to contaminate because it´s found in aquifers below the surface of the arth, making by these factories to reach these places; althouh not impossible.
Place the steps of biofilm formation in the correct order: 1. Quorum sensing and the establishment of the extracellular matrix commences as microbes attach more stably. 2. Surface (substratum) is preconditioned by environmental molecules. 3. Biofilm matures and some microorganisms escape to the planktonic state. 4. Microbes attach and detach from the preconditioned surface.
Answer:Step order:
2. The surface (substrate) is preconditioned by environmental molecules.
4.Microbes bind and detach from the preconditioned surface.
1.Quorum detection and extracellular matrix establishment begins as microbes bind more stably.
3. The mature biofilm and some microorganisms escape the planktonic state.
Explanation:
The biofilm is a highly complex structure where many microorganisms coexist, compete, reproduce, feed, within a micro-system with many ideal conditions for each microorganism that is housed in it.
The biofilm is resistant to non-selective antimicrobials, that is, to disinfectants such as sodium hypochlorite, chlorhexidine, among others.
Evidence was also presented that they are resistant to selective antimicrobials such as antibiotics, that is why they have great virulence factors or potential to trigger pathology.
The solution to destroy a biofilm is mechanical sweeping, with brushing as it happens on our teeth or even with the catheter cleaning brushes that are used (in addition to the sterilization methods).
This biofilm presents separate colonies in its interim with a fluid that it travels transmitting signals, food, toxins, resistant factors between these different types of microorganisms. This fluid and this communication between them is called quorum sensing and not all microorganisms tolerate it.
Many microorganisms compete with each other for the medium, an example is streptococcus mutating in the dental biofilm, which generates an acidic medium by metabolizing carbohydrates within the biofilm, thus generating that those bacteria that live in neutral or alkaline ph cannot reproduce and die.
The biofilm can be contained by bacteria, viruses, fungi and even parasites, but what they all have in common is that they have the ability to reproduce on an inert surface such as catheters, dental surfaces, silicone hoses.
