How far do scientists estimate the plates move in a year
Answer:
10 cm
Explanation:
They can move at rates of up to four inches (10 centimeters) per year, but most move much slower than that. Different parts of a plate move at different speeds. The plates move in different directions, colliding, moving away from, and sliding past one another. Most plates are made of both oceanic and continental crust.

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.

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 evidence supports the LAW OF CONSERVATION OF ENERGY?
1. Mechanical energy is converted to chemical energy during photosynthesis
2. Energy is absorbed by chlorophyll and becomes chemical energy during photosynthesis
3. Oxygen is made from the breakdown of carbon dioxide during photosynthesis
4. The sun gives off light energy that is absorbed by plants
The evidence that supports the law of conservation of energy is as follows: mechanical energy is converted to chemical energy during photosynthesis.
LAW OF CONSERVATION OF ENERGY:The law of conservation of energy states that energy can neither be created nor destroyed but is changed from one form to another. This means that energy involved in chemical reactions and natural phenomena is recycled by transformation and doesn't get destroyed. A typical example that obeys this law is photosynthesis, which converts mechanical energy in sugar molecules to chemical energy in ATP.Learn more about law of conservation of energy: https://brainly.com/question/2264339

Given what you learned about how influenza changes over time, how could you explain the emergence of drug resistance in bacterial pathogens?
Answer:
Beneficial mutations events can generate resistance to drugs
Explanation:
Bacteria can develop antibiotic resistance through mutations, as well as horizontal transference events, that allow them to reduce/eliminate the effectiveness of drugs used to treat infections. For example, penicillin-resistant strains have been identified in Staphylococcus aureus and Streptococcus pneumoniae. In general, mutations have a negative impact on the fitness of the organism; however, there are cases where mutations increase the fitness of the individual. In consequence, antibiotic resistance may occur by natural selection, where antibiotic-resistant bacteria that exhibit beneficial mutations are selected to survive and perpetuate their genetic material.

The decimal reduction time (DRT) to kill 90% of cell present for autoclaving a culture is 1.5 minutes. How long would it take to kill all the cells if 106 cells were present? What would happen if you stopped the heating process at 9 minutes?
Answer:
10.5minutes
Explanation:
DRT = 90%
Cells present = 10^6
Autoclaving = 1.5 minutes
Solution:
10^6(1.5)10^5(1.5)10^4(1.5)10^3(1.5)10^2(1.5)10^1(1.5)10^0(1.5)0=10.5
it would take it approximately 10.5 minutes to kill 10^6 of the cells.
If i should stop the heating process at 9 minutes this would have effect on some of the microbes as they are still present with 1 bacterium left which makes it not efficient.

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.

How are the enzymes that nerve cells produce different from the enzymes that blood cells produce? A. The molecules that nerve cells digest are more complex than those digested by blood cells. B. The genes that are activated in nerve cells are different from those activated in blood cells. C. Nerve cells contain more ribosomes than blood cells. D. Nerve cells contain more mitochondria than blood cells.
Red blood cells carry a specific type of protein, called hemoglobin, which is able to bind oxygen and release it in other tissues. A nerve cell doesn't have this protein because it doesn't need to bind oxygen. Instead, the nerve cell uses other proteins that help it transmit signals to other cells.
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.
