Choose one of the two major phases of photosynthesis. Draw a model of that phase that corrects one of the weaknesses in the student’s original model.

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:

Therefore, differential reproductive success based on inherited traits best expresses natural selection.

Grey matter is a part of the central nervous system that is found on the surface of the brain.

It is a neural tissues that has alot of cell bodies of neurons, neuroglia and contain more unmyelinated axons and surronds the narrow central canal.it is distinguished from white matter because it has alot of cell bodies and unmyelinated axons and also it is not as white as white matter with greyish color.

Answer:

Answer:C) The patient may have internal bleeding and cuts may not stop bleeding.

Explanation:

Platelets are cells that form scabs to help stop the bleeding of wounds. When you have low platelets, you can have fewer scabs at a time, so wounds will bleed more. If you have dangerously low platelets, any wound you have will not close and you will not stop bleeding without outside help.

Madison lives near the ocean. She’s formed a hypothesis that increased concentrations of salt in the air speeds the corrosion of certain metals. If Madison plans to test this hypothesis, she will have to deal with the following variables in her experiment: dependent variable: independent variable: one possible confounding variable:

Answer:

A variable, which is under study or observation in an experiment and changes concerning the independent variable is termed as a dependent variable. Based on the given experiment, Madison is checking the influence on the progression of corrosion of metals concerning the variations in the concentration of salt. This shows that the extent of corrosion of metals is a dependent variable.  

A variable, which can be controlled or monitored like increased or decreased, and one is familiar with is termed as an independent variable. This variable is not affected by another variable, like a change in the concentration of salt is the air may exhibit an effect on the corrosion of the metal, however, the process that is, the corrosion of metals does not affect the concentration of salt in the air. Hence, the independent variable is the salt concentration in air.  

A variable that possesses the tendency to change or influence both the independent and dependent variables is known as a confounding variable. If the airspeed is higher than it will carry the salt particles at a brisk rate and speed resulting in enhanced corrosion of metals. Likewise, if the speed of air is slower, there will be a reduction in the corrosion of metals. Hence, the confounding variable is the speed of air.

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:

A diving regulator is a pressure regulator that reduces the pressure of gas in the tank and deliver it to the diver so that he/she can breathe easily. It must pass the controlled laboratory testing and must have a second adjustment knob to ensure ease of breathing. Modern regulators are precision made and designed to work under demanding conditions. 1st stage and 2nd stage, diaphragm and piston, exhaust valve and purge button are types of diving regulators.

A scuba regulator is a pressure regulator that lowers the gas pressure in the cylinder and supplies it to the diver, making it easier for the diver to breathe. A second adjustment knob is needed to pass controlled laboratory tests and facilitate breathing. Modern regulators are precisely designed and designed for use in harsh conditions. The first and second stages, diaphragm and piston, exhaust valve, and flush button are a type of regulators.

The regulator is an excellent invention that provides exactly the air needed for breathing from the scuba tank. The regulator is the focus of the scuba gear and connects the scuba tank to BC, scuba pressure gauge (SPG), alternative air sources, and many other devices.

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.

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.

 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.
