Look at this map of current volcano hazards. Click a few volcanoes to determine their warning levels. Why is it possible to have a warning system for volcanoes? If you were a volcanologist, would you watch certain volcanoes on the map more than others?
It is possible to have a warning system for volcanoes because most volcanoes issue warnings before erupting.
As a volcanologist, certain volcanoes on the map will be monitored more than others because some volcanoes are more explosive than the others.
Why do volcanologist monitor volcanoes?Monitoring volcanoes enables volcanologist to understand its activities during an unrest through seismicity, deformation and degassing. Some volcanoes are explosive while others are not so the volcanologist has to monitor the type of magma that flows from it.
The volcanologist also uses the map as an indicator to know when any volcano is scheduled to erupt because some volcanoes provide warnings before eruption.

Answer:
By examining the pace of change in the gases released, the rate of change in seismic activity, the rate of change in ground deformation, and other variables, a volcanic eruption can be predicted. These are early warning indicators of an eruption. Volcanologists should concentrate on Kilauea and Shishaldin when studying the map because these two volcanoes are at the watch alert level and are more likely to erupt.

Reptiles first appeared at the end of the _____ era.
Cenozoic Era
Archean era
Mesozoic Era
Paleozoic Era
Reptiles first appeared at the end of the Paleozoic Era. Thus, option D is correct.
What are reptiles?Reptiles first appeared during the Paleozoic Era. The Paleozoic Era occurred around 542 to 251 million years ago. More specifically, reptiles first appeared in the Upper Carboniferous Period known as the Pennsylvanian Period, which was from 323.2 to 298.9 million years ago.
Emergency procedures are processes that needs to have a quick action to arrive at a fast resolution. But it must still be conducted in an orderly manner. An elective procedure is a planned surgery. It is subjected to choice or election.
During the early period of the Paleozoic era (The Cambrian), there existed marine living organisms (phyla). During the Paleozoic era, volcanic activity was experienced. Lastly, the Paleozoic era was a geologic period that was prone to erosion and deposition of marine fossils.
Therefore, Reptiles first appeared at the end of the Paleozoic Era. Thus, option D is correct.

There are three plants, A, B, and C. Plant A is placed in a solution of the same solute concentration as that of the plant's cells, plant B is
placed in a solution of a higher solute concentration than that of the plant's cells, and plant C is placed in a solution of a lower solute
?concentration than that of the plant's cells. A cell of each plant is examined under the microscope. Which plant has the most tense cell walls
[tex]{ \: \: \: \: \: \: \: }[/tex]
Plant A is present in an isotonic solution; plant B is present in a hypertonic solution; and plant C is present in a hypotonic solution. The most tense cell out of three is cell C, which is present in the hypotonic solution as water goes into the cell.
What is a hypotonic solution?
The cell present in a solution can either take or lose water, and that depends upon the outside solute concentration or water potential. The plant cell A is present in the solution at an equal concentration of solutes, which means that the water potential is the same at both ends, that is, outside and inside, preventing any flow of water.
In plant B, the outside solution has more solutes than the water, so it has less water than that of the cell, and in this case, water will flow from the cell to the outside, resulting in a decrease in cell size. In cell C, the solution has low solutes, which means high water, so in this case, the water will flow from the outside to the inside and make the cell swell and more pressure on the cell wall.
Hence, cell C has a more tense cell wall.

Answer: it is drought
Explanation:
Answer:light
Explanation:In some cases, poor environmental conditions (e.g., too little water) damage a plant directly. In other cases, environmental stress weakens a plant and makes it more susceptible to disease or insect attack. Environmental factors that affect plant growth include light, temperature, water, humidity and nutrition.

Solution to reduce the damaging effects of an El Niño or las Nina event is alternating extreme weather condition which emanates from east central equatorial pacific ocean
El Niño is usually associated with rising sea level which raises temprature beyond normal and resulting into events such as flooding and rainstorm and El Niño effect can be curtailed by building storm resist structure in affected area while also ensuring good drainage system to reduce the effect of flooding's and more than 60 million around the world have been impacted and people whose livelihood depend in agriculture, fisheries and livestock's are particularly affected and hence resulting in extreme weather condition in some other location on earth

if the wet bulb depression is 3 degrees and the dew point is 24 degrees, what is the relative humidity?
if the wet bulb depression is 3 degrees and the dew point is 24 degrees, relative humidity would be approx. 66%
What is relative humidity?
Relative humidity, often expressed as a percentage, indicates a present state of absolute humidity relative to a maximum humidity given the same temperature. It is a measure of how much water vapor is in a water-air mixture compared to the maximum amount possible.
Moreover, it measures the density of water vapor in a space relative to the temperature in the same space.
Calculate relative humidity RH using the formula, RH = 100 × {exp[17.625 × Dp/(243.04 + Dp)]/exp[17.625 × T/(243.04 + T)]}

Why is it important that a pure water IV not be given to dehydrated patients?
Pure water IV is not given to a dehydrating patient because our circulation already includes some salt, IVs also contain saline, a solution of water and salt that is almost isotonic with blood. Water flows from a high concentration to a low concentration, preventing the cells from exploding.
What would happen if you injected pure water into a patient?Patient would pass away. The cell would rupture owing to osmosis because of the disparity in salt content between the interior and exterior. In order to establish an isotonic state, the water would exit the cell and switch from the less concentrated inside to the more concentrated outside, killing the cell and ultimately the patient.
Hence, Continuous monitoring is necessary when receiving a saline water IV injection to make sure the IV solution is giving the patient the proper amount of fluids and minerals.

Answer:
B.
Explanation:
Photosynthesis is basically plants using sunlight (or any light) to make 'food'.
Plants, algae, and cyanobacteria that contain chlorophyll engage in the most prevalent and important type of photosynthesis. These organisms absorb solar energy and transform it into chemical energy contained in the molecules of carbohydrates by using carbon dioxide and water. Thus, option B is correct.
What are the process involving in photosynthesis?The three episodes that occur during the photosynthesis cycle are: Light energy is absorbed by chlorophyll, which breaks down water molecules into oxygen and hydrogen. Light energy is converted into chemical energy. The reduction of carbon dioxide leads to the formation of carbohydrates.
The photosynthetic cycle contains three stages, which are as follows: Light energy is absorbed by chlorophyll, which then divides water molecules into oxygen and hydrogen. Light energy is converted into chemical energy. Carbon dioxide is reduced, which results in the creation of carbohydrates.

The age of the sample from the half life is 2.1 * 10^9 years.
What is the age of the sample?We know that when radioactivity is taking place, the parent nucleus would disintegrate and the daughter nucleus is formed. We can know the amount of the parent and daughter isotope as it is in the question.
We mow need to find the age of the sample from;
N/No = (1/2)^t/[tex]t_{\frac{1}{2} }[/tex]
N = Number of atoms that remain after time t
No = Number of atoms originally present
t = age of the sample
[tex]t_{\frac{1}{2} }[/tex] = Half life of the sample.
To obtain the age of the sample;
0.125No/No = (1/2)^t/704 * 10^6
0.125 = (1/2)^t/704 * 10^6
(0.5)^3 = (0.5)^t/704 * 10^6
