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
A plant that was grown in the dark continuously would: ________.
a. not be able to take in CO2 without sunlight.
b. remain healthy because plants have stored materials in their roots that can provide what the Calvin cycle needs.
c. not be able to split water to provide NADH.
d. continue to photosynthesize because to in carbon dioxide, the only outside input to the Calvin cycle, does not require sunlight.
Answer:
c. not be able to split water to provide NADH.
Explanation:
Photosynthesis, which is the process by which plant species obtain their energy, occurs in two stages viz: light dependent phase and light independent phase. The light dependent phase of photosynthesis requires the energy from sunlight, which is captured by the chlorophyll pigments in the leaves of the plant.
The light energy captured by the chlorophyll is used to split water molecule in a process called PHOTOLYSIS OF WATER. Overall, ATP and NADH (electron donor) are products of the light dependent stage, which enters the next stage to complete the photosynthetic process.
Therefore, a plant that was grown in the dark i.e. no access to light, continuously would not be able to capture light energy and hence not be able to split water to provide NADH.
A plant that was grown in the dark spontaneously would not possess the tendency to split water to provide NADH.
What is photolysis of water?The process by which the species of plant attain their energy, that is, photosynthesis, takes place in two stages:
Light independent phaseLight dependent phaseIn the light dependent phase, energy is needed from sunlight, and is captivated by the chlorophyll pigments present in the leaves of the plant. This energy from the light is used to split the molecule of water by a process known as photolysis of water.
The products of the light dependent stage is ATP and NADH that enters the next phase to complete the process of photosynthesis. Therefore, a plant, which was grown in the dark, that is, having no accessibility to light, would not possess the tendency to captivate the energy from the sunlight and thus would fail to split the molecule of water to provide NADH.
Thus, the correct answer is option c.

which ground tissue is a major component of the blades of spinach leaves
Answer:
Parenchyma
Can i have brainliest?
Parenchyma is the ground tissue that is a major component of the blades of spinach leaves.
The fundamental tissue is made up of parenchyma cells located in leaves, stem and roots; responsible for photosynthesis or storing substances.
The parenchyma tissue is located under the epidermis, although it does not fulfill the photosynthetic function, if not that of serving as a storage tissue, the endodermis is located under the parenchyma.
The parenchymal cells in the cortex have a loose arrangement with air spaces between them and connected to each other to be able to transport water and nutrients through them.The pericycle is a group of parenchymal cells that surround the xylem and phloem.The parenchyma serve as storage and tissue that fills a space inside the stem.Therefore, we can conclude that parenchyma is the ground tissue that is a major component of the blades of spinach leaves.

Which of the three traits considered in this film (bipedality, extensive tool use, and large brains) were present in the 3.2-million-year-old Australopithecus fossil (Lucy)?.
Answer:
The bipedality
Explanation:
One of the things the discovered fossil signified was that human bipedality was more ancient than the large brain size because Lucy actually had a small skull which could indirectly be translated to small brain size.
NOTE: Bipedality can be described to mean the ability of an organism to move about with two legs. Hence, it must have been discovered that Lucy had two legs.

Forests dominated by gymnosperms tend to have mechanisms to allow it to regenerate after a fire. As a consequence this type of forest ______________.
a. dominate areas where the U.S Forest Service does not put out fires.
b. only lives 20-30 years
c. is dominated by trees of a single age
d. has no overstory species
Answer:
Forests dominated by gymnosperms tend to have mechanisms to allow it to regenerate after a fire. As a consequence this type of forest is dominated by trees of single age .
Explanation:
It is possible to conclude the question given above in many ways. After a forest fire in a specific forest patch occurs, the impacts are determined by the severity of the fire and the type of forest in which the occurrence occurs. Usually, the dramatic effect on the trees and plants that can be seen in that region can be seen after such an occurrence has occurred. In certain situations, the situation can also worsen, leading to the destruction of the entire cover, if the circumstances favor the propagation of fires. In such cases, the removal of the prevailing structure can lead to the formation of a new forest structure through a mechanism called 'succession,' in which there is a sequence of progression in a biologically acceptable manner through the growth of different plant species. Simply put, the new plants will attempt to adapt or acclimatize to the conditions introduced after forest fire in such a way that this will later provide the route for the growth of plants and trees that can not easily accommodate in the harsh conditions. Therefore, instead of the forest surviving for a short period of time following a forest fire occurrence, there would be changes in the nature of the forest. This suggests that option 'B' is not the response that is most suitable.Choice 'A' appears to be logically inaccurate, taking into account that if they are of high intensity, fires may be uncontrollable. In addition, there is no clear mention of the fire's region of origin and which trees are most affected. Typically, gymnosperms illustrate a simple process in which they can not limit their destruction from the flames, while they can provide a way for their progeny to initiate next generation development in the form of seed. This occurs in the case of Gymnosperms in which, under ordinary conditions, the seeds of the plants are enclosed within a cone that is restricted from germinating. Although the fires pave the way for the seeds to germinate under certain fire conditions, which in turn leads to the emergence of the next generation of gymnosperms, and several studies indicate that these newly introduced seeds would have the same age as choice 'C' indicated. But, as this is not under the jurisdiction of the US Forest Service, legally, option 'A' tends to be wrong. At the same time, it can be seen that forest fires are not consistent in their coverage in certain cases, and thus the chances of dispersal and germination tend to be not even and thus choice 'C' can be reported to be either correct or incorrect in all possible ways.But, first, it is important to know what an overstory is for the option 'D'. A forest consists of trees of all sizes, from the smallest to the tallest pine trees. The uppermost element that is directly in contact with the light from the sun is the overstory. The manner in which the degree of overstory damage occurs depends on the moisture content of the trees and the other associated conditions around the trees. Taking this into account, a forest fire may either lead to the loss of an entire overstory or can have impacts that are confined to plants and trees at the ground level. So, even the 'D' option can be right or inappropriate. But, therefore, choice 'C' should be the most suitable response, taking into account that most studies indicate growth of single-age trees due to germination mediated in the presence of fire. This seems to be scientifically right for a small patch where there was also fire-mediated damage. Accordingly, the most suitable response should be option 'C'.Hence , the correct option is C.
Two different groups of scientists studying a rare trait in ground squirrels report very different heritabilities. What factors influencing heritability values make it possible for both conclusions to be correct?
Answer:
It is a trait highly influenced by environmental factors (i.e., it has low heritability)
Explanation:
In population genetics, heritability is a statistical measure to estimate the proportion of the phenotype variation of a given trait which can be explained by hereditable genetic factors. The heritability of a trait is influenced by environmental factors, genetic factors (e.g., allele frequencies, number of genes involved in trait variation, recombination rate, etc), and the interaction between genetic and environmental factors. A low heritability value suggests that most of the variation is not genetic (i.e., due to environmental factors), while a high heritability value suggests that almost all of the variability in a trait is due to genetic factors.

What is the process that occurs when a recipient eukaryote cell accepts DNA gragmets indirectly from the surrounding environment?
Answer:
horizontal gene transfer
Explanation:
Horizontal Gene Transfer (HGT) can be defined as a non-sexual process that enables the exchange of genetic information between genomes. Although HGT mainly occurs between prokaryotic genomes, an increasing number of examples involving eukaryotic host genomes have recently been described. Agrobacterium bacteria are capable of transferring and integrating DNA into the genome of eukaryotic cell hosts by the HGT mechanism. The transference of genetic material via Agrobacterium-mediated transformation is widely used in biotechnology to generate plants with desired genetic sequences. In the last years, it has been shown that various bacterial species including Bartonella henselae Rhizobium etli or even Escherichia coli, are able to genetically transform eukaryotic cells under laboratory growth conditions. The genetic phenomenon of horizontal gene transfer has evolutionary significance since it enables to bypass barriers between kingdoms in order to acquire nucleotide sequences that may eventually have some adaptive advantage. Moreover, the mechanism of horizontal transfer challenges a narrow vision of the eukaryotic genome as a fixed entity.

. How are mineral deposits formed around vents?
Answer:
When hot, metal-laden water spews from vents and mixes with the cold ocean, the metals precipitate. Large piles of sulfide accumulate on the seafloor and are eventually buried by sediments, modified by heat and pressure in the crust, and uplifted. Some are exposed on land when erosion removes the overlying rocks.

The maintenance of relatively constant internal environment of an organism is called Homeostasis.It is an automatic regulations of the body systems and organs controlled by the brain and some receptors, specific for certain body fluctuations.E.g Thermoreceptors Chemoreceptors etc.
The fluctuations in the body internal systems must be controlled within a narrow limits, for existence of living organism.The brain receives inputs from the receptors, and the outputs from the brain ensures the homeostatic control.
The above examples are typical homeostatic responses by the organisms involved, because the inputs from the receptors send signals to the brain ,and the organisms responded to these with the example above.
