Transpiration is the process of release of water from the plants. In the absence of transpiration, the plant bursts. Thus, option D is correct.
How the process of transpiration takes place?The transpiration process is the release of water from the plants through stomata. The pressure of water allows the movement of the stomatal guard cell, and the stomata opens.
The opening of stomata releases the water inside the plants, and release of pressure results in the relaxation of stomata, thereby closing the stomata.
The absence of transpiration in plants results in the accumulation of water inside the body. The access water in the body exerts the force to the plant body, and it may burst.
Therefore, in the condition of loss of transpiration by the plants, the plant may burst out. Thus, option D is correct.

Which formulas shows the relationship between momentum, mass and velocity
Answer:
P=m*s
Explanation:
The linear momentum of a particle of mass m or body m moving with a speed v is defined as the product of the mass times the speed:
P = m * v
Where, as previously stated, P = moment, m is the mass of the body, v is the speed.
The standard units for moment are [tex]kg*\frac{m}{s}[/tex], and moment is always a vector quantity. Its direction and direction coincide with those of the velocity vector.
Describe three signs that a chemical reaction has taken place and give an example of each sign
Change in state, change in color, and change in odor are three signs that a chemical reaction has taken place.
What is a chemical reaction?A chemical reaction is a process in which the atoms or molecules of one or more substances (known as reactants) are rearranged to form one or more different substances (known as products).
During a chemical reaction, chemical bonds between atoms are broken and new bonds are formed between different atoms. It results in the creation of new chemical compounds with unique properties.
Chemical reactions can be represented by chemical equations that show the reactants and products involved in the reaction. These reactions can be exothermic (releasing energy) or endothermic (requiring energy). They play a crucial role in various natural and industrial processes.

which of the following equations does not demonstrate the law of conservation of mass
The equation P4 + SO2 → 2P4O10 does not demonstrate the law of conservation of mass.
What is law of conservation of mass?According to law of conservation of matter, "the mass in an isolated system can neither be created nor be destroyed but can be transformed from one form to another."The law of conservation of matter is a general law in chemistry applicable for any system closed to all transfers of matter and energy.According to this law, the mass of a substance or an object never changes over time, no matter how the constituent parts rearrange themselves. To put it in simple words, the mass can neither be created nor be destroyed.In equation P4 + SO2 → 2P4O10, the mass of the reactants are not equal to the mass of the products. Therefore, this equation does not obey the law of conservation of mass.

Describe the acceleration of your bicycle as you ride it from your home to the stoe
The acceleration of your bicycle can vary depending on the situation. If you are riding at a constant speed, your acceleration would be zero. However, if you are starting from rest or changing your speed, you would have a non-zero acceleration.
Explanation:The acceleration of your bicycle as you ride it from your home to the store can vary depending on the situation. If you are riding at a constant speed, your acceleration would be zero because acceleration is the rate of change of velocity, and constant speed means there is no change in velocity. However, if you are starting from rest and gradually speeding up or slowing down, then you would have a non-zero acceleration.
For example, if you start from rest at your home and gradually increase your speed as you ride to the store, your acceleration would be positive. On the other hand, if you start at a high speed and gradually slow down as you approach the store, your acceleration would be negative.
It's important to note that acceleration is a vector quantity, meaning it has both magnitude and direction. So, depending on the direction of your motion, the acceleration could be positive or negative.

Which term names the underground region between where water saturates pores and where it does not? A. water zone B. water table C. aqua zone D. porous zone
Water table is the underground region between where water saturates pores and where it does not.
Answer: B
Explanation
It is known that water is present below the ground. The rocky terrain inside the ground contains water and the water will be filled in the pores between the rocks.
The water filled in the saturated region below the ground is separated from the unsaturated region which is the region above the ground by a surface termed as water table.
The unsaturated region is the soil above the ground and the plants get water from this region.
The water is present in unsaturated region occupy between the pores of rocks and soils but they are loosely filled so that plants can extract water from them.
Then below the ground water table region will be present and below the water table the saturated water region is present.
So water table is the region dividing the saturated and unsaturated water pore regions.

A balloon with a volume of 0.851 L holds 0.783 mol He gas at a temperature of 150.0 K. The temperature then increases to 305 K, and the pressure is changed to 0.800 atm. The original pressure of the gas was ______ atm. The final volume of the balloon is _____ L.
Answer:
Original pressure = P1 = 11.3 atm
Final volume = V2 = 24.5 L
Explanation:
Given data:
Initial conditions:
Volume V1 = 0.851 L
Temperature T1 = 150.0 K
Moles of He n1 = 0.783
From ideal gas equation:
[tex]PV = nRT\\\\P = \frac{nRT}{V}[/tex]
Substituting the initial V, T and n using R = 0.0821 L.atm/mol-K we get:
[tex]P1 = \frac{0.783*0.0821*150.0}{0.851} = 11.33 atm[/tex]
Final conditions:
T2 = 305 K
P2 = 0.800 atm
Since the number of moles of He will remain constant we can write:
[tex]\frac{P1V1}{T1} = \frac{P2V2}{T2} \\\\V2 = \frac{P1*V1*T2}{T1*P2} = \frac{11.33*0.851*305}{150*0.800} =24.50 L[/tex]
