The town in this image is near an inactive volcano. If the volcano were to violently erupt, which location would be least affected by volcanic ash and lava?
Answer:
i think it is the state park im not sure but lmk if im wrong or right
Explanation:
The correct answer is the plane, as it is flying in the sky, but the lava from the volcano after its eruption can easily flow down to the park, hospitals, etc., and the plane is least about to be affected by the volcanic eruption.
What is a volcanic eruption?A volcanic eruption is a natural phenomenon that occurs when magma, ash, and gases are expelled from a volcanic vent or fissure in the Earth's surface. Volcanic eruptions can range from relatively small and quiet to explosive and violent, and they can have significant impacts on the environment and on human populations. Volcanic ash and lava can be carried by the wind over large distances, so the direction of the wind and its strength are important factors in determining which areas will be most affected. Areas that are located upwind from the volcano are likely to be more affected by volcanic ash and lava than areas that are located downwind.
Hence, the correct answer is the plane, as it is flying in the sky, but the lava from the volcano after its eruption can easily flow down to the park, hospitals, etc.

Answer:
B. The pea flowers are pollinated at random.
Explanation:
Hardy-Weinberg equilibrium states that allele and genotype frequencies will remain same in next generations without any evolutionary influence among a population.
If the pea flowers are pollinated at random, then the population will not follow Hardy-Weinberg equilibrium because random pollination give rise to variation among the population as flower will pollinate randomly and allele and genotype frequencies varies showing both tall and recessive alleles.
Hence, the correct answer is "B".
Answer:
One pea plant pollinates more flowers than the others

[tex] \Large{ \boxed{ \bf{ \color{blueviolet}{Required \: answers:}}}}[/tex]
1) An eclipse takes place when one heavenly body such as a moon or planet moves into the shadow of another heavenly body. There are two types of eclipses on Earth:
An eclipse of the moon An eclipse of the sun.2) Most years have 4 eclipses, which is the minimum number of eclipses that take place in a year; 2 of these 4 eclipses are always solar eclipses. While rare, the maximum number of eclipses that can take place in a calendar year is 7.
3) Differences:-
Solar eclipses happen at new moon. Lunar eclipses happen at full moon.Solar eclipses are only visible from a narrow strip of land over which the Moon shadow passes. Lunar eclipses are visible from the whole nighttime hemisphere.Solar eclipses can be total, annular, hybrid or partial. Lunar eclipses can be total, partial and penumbral.Solar eclipses can only be safely be viewed with the naked eye during totality. Lunar eclipses can always be safely viewed with the naked eye.The Moon's surface can't be seen during a solar eclipse, but it can be during a lunar eclipse.4) Moon phases:
We only see the Moon because sunlight reflects back to us from its surface. During the course of a month, the Moon circles once around the Earth. If we could magically look down on our solar system, we would see that the half of the Moon facing the Sun is always lit. But the lit side does not always face the Earth! As the Moon circles the Earth, the amount of the lit side we see changes. These changes are known as the phases of the Moon and it repeats in a certain way over and over.
5) The moon moves in an orbit around Earth, and at the same time, Earth orbits the sun. Sometimes Earth moves between the sun and the moon. When this happens, Earth blocks the sunlight that normally is reflected by the moon. Instead of light hitting the moon’s surface, Earth's shadow falls on it. This is an eclipse of the moon -- a lunar eclipse.
Sometimes when the moon orbits Earth, it moves between the sun and Earth. When this happens, the moon blocks the light of the sun from reaching Earth. This causes an eclipse of the sun, or solar eclipse. During a solar eclipse, the moon casts a shadow onto Earth.
6) The moon can look red during a total lunar eclipse because of sunlight that's filtered and refracted by Earth's atmosphere.
7) 50% of the lunar surface is always illuminated by Sun. Because half of the moon surface is lit, rest we can't see.
8) When the moon passes between the sun and Earth, it can create a solar eclipse. When the disk of the moon masks the disk of the sun, it creates a total solar eclipse. Lunar eclipses occur when Earth passes between the sun and the moon. During a lunar eclipse, the moon turns dark red due to the deviation of the sun's rays caused by Earth's atmosphere. Lunar eclipses occur more often and last longer.

Suppose that you are in charge of designing a fracking job site. Which of these locations would be most ideal for the site?
Answer:
B. On a flat, vacant plot in the outskirts of the city
Explanation:
Fracking, also known as hydraulic fracturing is a drilling method used in the oil and gas industry of most countries. It is the process whereby natural gas and petroleum is extracted from deep down the Earth. A crack is made in the rock layers, followed by the injection of a liquid called fracking liquid, which is usually water, at a very high pressure.
The process of fracking has serious environmental side effects e.g. release of harmful gases, noise pollution, water contamination etc. and hence, when choosing a fracking site, environment's sustainability and safety of people should be taken into account. This is why a fracking site cannot be designed in a residential city or around a neighborhood. The site should rather be designed in a location where it would pose a minimal environmental threat to the people e.g flat, vacant plot in the outskirts of the city

Answer:
The goal of disinfection of public water supplies is the elimination of the pathogens that are responsible for waterborne diseases. The transmission of diseases such as typhoid and paratyphoid fevers, cholera, salmonellosis, and shigellosis can be controlled with treatments that substantially reduce the total number of viable microorganisms in the water.
While the concentration of organisms in drinking water after effective disinfection may be exceedingly small, sterilization (i.e., killing all the microbes present) is not attempted. Sterilization is not only impractical, it cannot be maintained in the distribution system. Assessment of the reduction in microbes that is sufficient to protect against the transmission of pathogens in water is discussed below.
Chlorination is the most widely used method for disinfecting water supplies in the United States. The near universal adoption of this method can be attributed to its convenience and to its highly satisfactory performance as a disinfectant, which has been established by decades of use. It has been so successful that freedom from epidemics of waterborne diseases is now virtually taken for granted. As stated in Drinking Water and Health (National Academy of Sciences, 1977), "chlorination is the standard of disinfection against which others are compared."
However, the discovery that chlorination can result in the formation of trihalomethanes (THM's) and other halogenated hydrocarbons has prompted the reexamination of available disinfection methodology to determine alternative agents or procedures (Morris, 1975).
The method of choice for disinfecting water for human consumption depends on a variety of factors (Symons et al., 1977). These include:
its efficacy against waterborne pathogens (bacteria, viruses, protozoa, and helminths);
the accuracy with which the process can be monitored and controlled;
its ability to produce a residual that provides an added measure of protection against possible posttreatment contamination resulting from faults in the distribution system;
the aesthetic quality of the treated water; and
the availability of the technology for the adoption of the method on the scale that is required for public water supplies.
Economic factors will also play a part in the final decision; however, this study is confined to a discussion of the five factors listed above as they apply to various disinfectants.
The propensity of various disinfection methods to produce by-products having effects on health (other than those relating to the control of infectious diseases) and the possibility of eliminating or avoiding these undesirable by-products are also important factors to be weighed when making the final decisions about overall suitability of methods to disinfect drinking water. The subcommittee has not attempted to deal with these problems since the chemistry of disinfectants in water and the toxicology of expected by-products have been studied by other subcommittees of the Safe Drinking Water Committee, whose reports appear in Chapter III of this volume (Chemistry) and Chapter IV (Toxicity) of Drinking Water and Health, Vol. 3.
Organization of the Study
The general considerations noted in the immediately following material should be borne in mind when considering each method of disinfection. Available information on the obvious major candidates for drinking water disinfection—chlorine, ozone, chlorine dioxide, iodine, and bromine—is then evaluated for each method individually in the following sections. Other less obvious possibilities are also examined to see if they have been overlooked unjustly in previous studies or if it might be profitable to conduct further experimentation on them. Disinfection by chloramines is dealt with in parallel with that effected by chlorine because of the close relationship the former has to chlorine disinfection under conditions that might normally be encountered in drinking water treatment.
A mutation in human ATPase 6, which corresponds to E. coli subunit a, from leucine to arginine at position 156 may allow the movement of protons across the membrane, but not the rotation of the ring of c subunits. How might this possible mechanism affect the function of ATP synthase
Answer:
H+ protons will not be delivered from the cytoplasm towards the extracellular side of the cell membrane
Explanation:
ATP synthases are enzymes that catalyze the hydrolysis of phosphate bonds in the adenosine triphosphate (ATP) or the formation of ATP from adenosine diphosphate (ADP) and phosphate. The hydrolysis of ATP produces the rotation of a ring composed of six or more structurally different ATPase C subunits. The rotation of this ring enables the delivery of H+ protons towards the extracellular membrane surface and this gradient is used to generate energy by producing ATP. In consequence, when the ATPase ring can not move, H+ will accumulate in the cytoplasm, the proton gradient through the membrane will not occur, and ATP will not be produced.
how do each of the following factors affect the productivity in this process of photosynthesis ? 1)Temperature 2) Water 3) carbondioxide
Answer:
without the right amount of temperature and water photosynthesis won't take place and without the presence of carbon dioxide...there is nothing like photosynthesis
Explanation:
1) Temperature- Above 28°C of temperature photosynthesis will not take place faster as necessary. At this temperature, the enzymes responsible for photosynthesis will not work efficient as needed . 2)Water and 3)Carbon Dioxide-Water and carbon dioxide are the reactants in Photosynthesis which means they are taken in to produce energy. Six molecules of water and six molecules of carbon dioxide are needed to break apart glucose and produce energy.

Answer:
Passive transport.
Explanation:
Osmosis occurs in the cell which is a type of passive transport. Passive transport refers to the transfer of solutes from one place to another without the expenditure or use of energy. Osmosis refers to the transfer of solutes from outside the cell into inside the cell through a semipermeable membrane which allow solutes which are small in size. This process occurs only when the concentration of solute is different inside and outside of the cell. while active transport is a type of transport which transfer solutes from one place to another with the use of energy in the form of ATP.

Ecological carA hybrid ecological car, powered by solar energy and even electricity, brings numerous benefits to the environment. These vehicles are the ones that mix the use of electricity and fuel to move around. Generally, at low speeds, electricity is used as the main form of movement and gasoline only kicks in when high speeds are required.
The models powered by solar energy and electricity do not use fuel to move. The great advantage of this for the environment is the reduction in the emission of pollutants, such as CO2, which actively participates in the greenhouse effect and consequent global warming. With the use of ecological vehicles, our planet must become a better place to live.
With this information, we can conclude that choosing a car powered by renewable energy is the best option to choose, to maintain the ecological balance and health of the planet.

At temperatures higher than the maximum growth temperature for an organism:
a. proteins are permanently denatured. membranes become too fluid for proper function.
b. hydrogen bonds within molecules are broken.
c. hydrogen bonds are broken and proteins are permanently denatured.
d. hydrogen bonds are broken, proteins are denatured, and membranes become too fluid.
Answer:
The correct answer is option d, that is, hydrogen bonds are broken, proteins are denatured, and membranes become too fluid.
Explanation:
The maximum growth temperature refers to the highest temperature at which growth can take place. Let us take an example of bacteria, it is found that each bacterial species possess a requirement of specific growth temperature, which is mainly determined by the requirement of the temperature of its enzymes. Each of the organism exhibits an optimum growth temperature, a minimum growth temperature, and a maximum growth temperature.
When for an organism, the temperature goes more than its maximum growth than it results in the dissociation of the hydrogen bonds, denaturation of the proteins, and even the membranes become too fluid. This can even result in the death of the species. However, there are some of the organisms, which can thrive high temperatures known as thermoduric organisms, but they fail to grow effectively at such temperatures.
