Think critically A restaurant owner wants to serve fresh-cut fruit. What factors might be considered in choosing a recipe and preparation method
Answer:
Explanation:
1.Oxidation- some fruit after cutting on exposure to air begin to oxidate this leads to a change of color, this color change could range from light brown to dark brown in some fruits such as apple this could make it unappealing to to the consumer.
2. Shelf life- How long can the fruits start after exposure to air before it begins to loose its taste assuming they are not consumed immediately. This have to considered in selecting fruits
3. Time- How long will it take to prepare and make the fruits ready, some fruits requires some thorough cleaning, professional cutting skill
if all will be available and will meet up the time required for the fruits to be served.
All this are some of the factors needed to be considered

What sequence elements could be looked for within the inserted sequence that would help place it in one of the three families?
Answer:
DNA transposons, viral-like transposable elements, and non-LTR retrotransposons
Explanation:
Transposable Elements (TEs) are genetic mobile elements that can change its position within a genome, thereby producing mutations at the genomic sites where they are inserted. According to their composition and structure, TEs can be divided into three main types: DNA transposons, viral-like transposable elements, and non-long terminal repeat (non-LTR) retrotransposons (also known as polyA retrotransposons). In the first place, DNA transposons are composed of conserved inverted repeat sequences at both ends of the element which are surrounded by target site duplications (TSDs). Moreover, viral-like TEs contain LTRs and they encode reverse transcriptase enzymes. Finally, non-LTR retrotransposons contain a poly(A) tail at the 3′ end, but they don't have inverted repeats.

what solution describes a saturated solution?
Answer:
This is not my answer, I found it on the internet.
No more solutes can be dissolved in a saturated solution at a given temperature and pressure.
Explanation:
A saturated solution is a solution that consists of maximum amount and concentration of the solute that is dissolved in the solvent.
The extra amount of solute cannot be dissolved in a saturated solution.
The saturated solution is composed of solute and solvent and solvent cannot dissolve more solute at some extent.
The carbonated beverage is an ideal example of saturated solution.
A saturated solution is one that contains the greatest concentration and amount of the solute dissolved in the solvent. In a saturated solution, the excess solute cannot dissolve.
What is Saturated solution?Solvent and solute make up the saturated solution, and to a certain extent, solvent cannot dissolve more solute. A saturated solution is best exemplified by fizzy beverages.
A solute's solubility is the greatest amount of that solute that can dissolve in a solvent at a given temperature and pressure. The moles of solute per volume (mol/L) or the mass of solute per mass of solvent (g/g) are other common ways to express solubility.
There is typically a limit to how much solute can dissolve in a given amount of solvent, even for extremely soluble compounds. In general, temperature and pressure—for gases—as well as the energy components we have already covered affect a substance's solubility.
Therefore, A saturated solution is one that contains the greatest concentration and amount of the solute dissolved in the solvent. In a saturated solution, the excess solute cannot dissolve.

Place the steps involved in burning coal to create electricity in the correct order.
Water boils, creating steam.
Coal is burned
Turbines generate electrical energy.
Moving steam turns turbines.
Answer and Explanation:
Coal is burned: Electrical Centrals burn coal with which they get enough heat. The coal might be pulverized to increase the effective combustion area. Water boils, creating steam. The heat generated by the burning coal is used to create water vapor that rises and moves turbines. This occurs when water passing through some tubes is heated by the hot gases coming from the burning coal, turning it into high-pressure steam. Moving steam turns turbines. The high-pressure steam is taken to turbines where it expands and moves the rotor which is the moving part of the turbines. Turbines generate electrical energy. The turbines are connected to a generator that transforms the energy produced by the rotor into electricity.Answer:
Coal is burned
Water boils, creating steam
Moving steams turns turbines

Light behaves in specific ways. It can be reflected, refracted, or absorbed, and under certain conditions, run into different kinds of interference. Which explanation best describes why light is refracted as it enters water?
A. The light bends when it enters water due to its reflection.
B. The speed of light remains the same as it moves from air to water, causing the light to reflect.
C. The speed of light increases when it enters a different medium, but it doesn't bend.
D. The speed of light changes as it moves from air to water, causing the light to bend.
Answer:
D
Explanation:
Refraction is generally defined as the change in the direction of a wave as it travels from one medium to another. Light is a form of wave and light refraction is caused by a change in the speed of light as it moves from air to water, causing the light to bend in the process. The medium of travelling has to be transparent.
The change in the speed and direction is due to the variability in the refractive index of media. Light travels faster as it moves from a medium of higher refractive index to a medium of lower refractive index and vice versa.
The correct option is D.

What is wrong with this cell diagram ? (Giving brainliest)
Answer:
C
Explanation:
It has a round shape so obviously plant cell. You can see the vacuoles, mitochondria, and E.R., but it's missing its nucleus.
Answer:
D
Explanation:
A plant cell would have a cell wall to make the cell structured and more rectangular, so the other answer is incorrect. This is an animal cell. You can tell because there is no cell wall and the vacuoles are smaller (plant cells usually only have 1 large vacuole), and there are no chloroplasts. There is no nucleus pictured and since it is an animal cell, the cell doesn't need chloroplasts. That means that the answer is D.

Answer:
Pseudomonas aeruginosa
Escherichia coli
Staphylococcus aureus
Proteus vulgaris
Explanation:
Binomial nomenclature means a system of using two terms to describe the name of an organism.
It is a generally accepted system of nomenclature in biology. The first term represents the genus of the organism while the second name represents its specie.
The genus name begins with an uppercase letter while the species name is written in lowercase letters throughout.
The names of organisms in the answer section have been correctly written according to these rules.
The slow depolarization of the pacemaker cells is caused by the opening of the:_______.
Answer:
The slow depolarization of the pacemaker cells is caused by the opening of the non selective cation channels.
Explanation:
Pacemaker cells are specialized cardiac muscle cells with the task to create the rhythmic pulses that make the cardiac muscle contract properly, functioning as a whole and not as independent contractile cells.
One of the things that differentiate pacemaker cells from regular cardiomyocytes is that pacemaker cells slowly depolarize by themselves. This happens because when these cells are in phase 4, in a state of hyperpolarization, the 'funny current' appears to begin depolarizing the cell again.
Hyperpolarization usually occurs because there's an outflux of potassium ions (which makes the inside of the cell much more negative than the outside of the cell) but, in pacemaker cells, the membrane becomes less and less permeable to potassium, which ends up decreasing the outflux of this ion. Along with this change in potassium's electrical conductance, the funny current increases the permeability of sodium, which means that there's also a sodium influx happening at the same time, helping in the depolarization process.
This mixed sodium and potassium permeability is one of the key features of the funny current, and is possible thanks to the opening of non-selective cation channels in the membrane that allow the passing of any cation following their specific chemical gradients.
Victor has been studying the vascular systems of plants. He wanted to find out if food coloring would travel up the stalk of celery faster if the temperature of the water increased. Victor set up his experiment with three cups of colored water at different temperatures, three equal sized celery stalks, and a stopwatch. Cup A was filled with colored water at 21 C. Cup B was filled with cold colored water at 4 C, and Cup C was filled with warm colored water at 30 C. One celery stalk was placed in each cup at the same time. Victor timed how long it took the colored water to travel to the leaves at the top of the celery stalk. He measured the time in minutes. What is the independent variable
Answer:
temperature
Explanation:
The independent variable would be the colored water at different temperatures.
The independent variables are changeable or controllable variables supplied directly by researchers in the course of experiments. They produce effects on the dependent variable and are thus referred to as the 'cause' variable. The dependent variables are referred to as the 'effect' variables because their values vary based on that of the independent variables.
In this case, the only controlled variable of all the variables supplied by Victor is the temperature of the colored water. Changing the temperature of the colored water is expected to have effects on the time it will take for the colored water to travel to up the stalk of celery. Hence, the temperature is considered as the independent variable while the time it takes for the colored water to travel to the leave would be the dependent variable.

A peptide has the sequence of Gly-Ser-Glu-Leu-Ala-His-Gly-Arg-Leu-Ala-PheCys-Leu. (pKR=4.25, 6.0, 8.2, 12.5. Assume pKa’s of amino terminus and carboxyl terminus are 9.6 and 2.3, respectively.) The PI of the peptide is close to:_______
a. 7.1
b. 7.8
c. 5.1
d. 8.2
e. 10.3
Answer:
The correct answer is option a. "7.1".
Explanation:
One easy way to determine if a peptide sequence is acidic, basic or neutral is to check for the number of amino acid residues that are acidic, basic or neutral. In this case, most amino acid residues are neutral, which mean that under neutral conditions they have a pKa close to 7.0. Particularly, the content of 3 leucine, 2 alanine and 2 glycine residues determines that the peptide have a pI of around 7.1.

Answer:
Bare soil is exposed, weeds and grasses colonize, perennial plants are established, shrubs appear, trees appear, and forest results
Explanation:
This question describes a secondary succession, which is a colonization that occurs after a natural disaster has caused damage to an ecosystem. In secondary succession, SOIL, is already present, hence, there is rapid initial recolonization by GRASSES AND WEEDS.
The colonization of grasses and weeds is soon followed by the establishment of PERENNIAL PLANTS, after which SHRUBS appear, then TREES until a stable or climax ecosystem of FOREST results.

Answer:
The name of the test which can increase the accuracy of the identification of the organism is Coagulase testing.
Explanation:
Given the points stated in the question, the organism most likely under scrutiny here is Staphylococcus Aureus. Science has shown that it is the most harmful of all of the many different staphylococcal bacteria that there is.
The best test for differentiating and identifying Staphylococcus Aureus apart from other types of other Gram-positive cocci is the coagulase test.
The coagulase test checks to see if the microbe can produce an exoenzyme called coagulase.
Coagulase - an exoenzyme, is usually produced by bacteria. This enzyme triggers the coagulation of blood or plasma.
Only the pathogenic or disease-causing forms of staphylococcus can produce this enzyme. The enzyme is qualified by the suffice "exo" because the enzyme is secreted externally and not internally. Also, its functions are external, not internal.
The Coagulase testing is of two types:
The Slide TestThe Tube TestIt is usually safer to use the test tube method. If one must rely on the slide test, the results must be read quickly as it is prone to false positives.
