The Arizona poppy has adapted to living in areas that receive less rain, but there are still periods of time that a drought occurs. What part(s) of photosynthesis would the plant not be able to perform if there were no rain? What would be the long-term effects on the plant if the drought continues? Explain your answer.
Answer:
When plants lose more water than they can take up from the soil, they become water stressed. ... Such drought conditions certainly inhibit the growth of plants. If it goes long enough without water it will die because the plant uses water for a lot of different jobs needed to keep the plant alive, so the long-term effect is that the plant will die if the drought continues.
Explanation:
The Arizona poppy is the summer herb of deserts of southwestern US and has pinnately compound leaves and large snowy flowers. This poppy appears in rainy seasons.
Due to the drought like conditions and fast-changing climate the poppy plant has learnt to adapt to the harsh climate of Arizona and is able to carry out the process of photosynthesis. In the case of long-term drought conditions, the process of photosynthesis slows down as plant will absorb more light. This leads to stunted growth and possible death of the plant.Learn more about the Arizona poppy that has adapted to living in areas that receive less rain.

The density of manganese is 7.21 g/cm^3 . What is the density in kg/m^3 ? (dimensional analysis)
Answer:
7.21 x 103 kg/m3
Explanation:
Dimensional analysis has been the process to establish and convert the various units in the measurement. The density of manganese in kg/m3 is 7.21 × 10³ kg/m³.
What is dimensional analysis?Dimensional analysis has been the method that is also referred to as the unit factor or factor label method. It solves the mathematical expressions by multiplying the given value with another without changing its quantity and amount. It is used to change the units of the value.
Given,
Density of manganese = 7.21 g/cm³
The dimensional analysis method is used to convert grams per cubic centimeter into kilograms per cubic meter as:
1 gram / cubic centimeter = 1000 kilogram / cubic meter
So, 7.21 g/cm³ = X kilogram / cubic centimeter
Solving for X as:
X = 7.21 g/cm³ × 1000 kilogram / cubic centimeter
X = 7.21 × 10³ kg/m³
Therefore, 7.21 × 10³ kg/m³ is the density.

Which of these features of Earth's crust are caused by the shifting of tectonic plates?
A
mid-ocean ridges
B
desert sand dunes
С
arctic glaciers
D
continental shelves
To solve this we must be knowing each and every concept related to tectonic plates. Therefore, the correct option is option A among all the given options.
What is tectonic plates?The lithosphere, which includes the crust and topmost mantle, is divided into portions by tectonic plates. Numerous dangers, including volcanic eruptions, earthquakes, and tsunamis, are caused by the relative movement of tectonic plates.
Because of the makeup of the rocks inside the plates, tectonic plates can float on the mantle. This reduces their density relative to the mantle. Granite rock, which contains quartz, feldspar, as well as other relatively light materials mostly comprised of silicon and aluminum, makes up the continental crust. Mid-ocean ridges, earth's crust are caused by the shifting of tectonic plates.
Therefore, the correct option is option A.

Which of the examples represent potential energy A candy bar Wind A stretched rubber band Rowing a boat A ball rollinv down a hill A roller coaster at the top of a hill
Answer:
A candy bar
A stretched rubber band
A roller coaster at the top of a hill
Explanation:
Potential energy is the energy present as a result of the position of an object. This energy depicts zero motion or movement unlike kinetic energy.
A candy bar, stretched rubber band and roller coaster at the top of a hill all indicate positions without any said explanation of movement.
The other option choices depicts a type of movement .This is why the three option choices are correct in this scenario.
The examples that represent potential energy are:
A. A candy bar
B. A stretched rubber band
D. A roller coaster at the top of a hill
What is Potential energy?It is the stored energy in any object or system by virtue of its position or arrangement of parts. This energy depicts zero motion or movement unlike kinetic energy. For example : A candy bar, stretched rubber band and roller coaster at the top of a hill all indicate positions without any said explanation of movement.

9. How many grams of zinc are needed to produce 12 grams of zinc chloride according to the following equation? Y-
Zn + Cl2 --> ZnCl2
12 grams of zinc
O 2.9 grams of zinc
O 11.6 grams of zinc
O 5.8 grams of zinc
Given :
A balanced chemical equation :
[tex]Zn +Cl_2->ZnCl_2[/tex]
To Find :
How many grams of zinc are needed to produce 12 grams of zinc chloride.
Solution :
Moles of [tex]ZnCl_2[/tex] ,
[tex]n=\dfrac{Given \ wt}{Molecular\ Mass}\\\\n =\dfrac{12}{136.30}\ mol\\\\n=0.088\ mol[/tex]
Now, by balanced chemical equation we can say that 1 mol of Zn produce
1 mol of [tex]ZnCl_2[/tex] .
So, 0.088 mol of Zn is required to produced 0.088 mol of [tex]ZnCl_2[/tex] .
[tex]Mass \ required = molecular \ mass \times moles\\\\m = 65.38 \times 0.088\\\\m=5.8 \ gm[/tex]
Therefore, 5.8 grams of zinc is required.
Hence, this is the required solution.
