Cells are open systems that exchange matter and energy with their surroundings. Which of the following best explains why plant cells require sunlight to make organic compounds, according to Gibbs’s theory of free energy? The energy input required for making organic compounds equals the usable energy output of respiration. The energy required from sunlight to start photosynthesis is less than the energy needed from another energy source. The energy required to make organic compounds is always greater than the potential energy stored in these compounds. The energy that a plant absorbs from sunlight is spontaneously transformed into chemical energy because the outputs are more stable.
Answer:
The energy input required for making organic compounds equals the usable energy output of respiration.
Explanation:
A reaction is endergonic (energy-consuming) process if the change in free energy is positive.
A positive change in free energy implies that energy is required to enter into the system. Let us recall that free energy is a state function. Hence, change free energy =free energy of products - free energy of reactants.
If free energy of products > free energy of reactants then the reaction is an endergonic (energy-consuming) process..
But The energy input required for making organic compounds equals the usable energy output of respiration, hence making the process spontaneous.
The following best explains why plant cells require sunlight to make organic compounds, according to Gibbs’s theory of free energy - The energy that a plant absorbs from sunlight is spontaneously transformed into chemical energy because the outputs are more stable.
photosynthesis
is a process that occurs in the presence of sunlight in order to derive energy.
These organisms by doing work release energy into the environment.The energy released into the environment is in form of heat.Plants release energy into the atmosphere when they do any work. they also release energy in the surrounding.It is an open system where energy can be transferred from one part of the system to another part of the system.Plant cells require sunlight to make organic compounds, according to Gibb's theory of free energy because, the energy that a plant absorbs from sunlight is spontaneously transformed into chemical energy because the outputs are more stableThus, The following best explains why plant cells require sunlight to make organic compounds, according to Gibbs’s theory of free energy - The energy that a plant absorbs from sunlight is spontaneously transformed into chemical energy because the outputs are more stable.

All of the following are ways that animals maintain homeostasis and cool down except
flapping their wings.
sweating.
panting their tongues.
the production of goosebumps.
Answer:
flapping their wings
Explanation:
Homeostasis is a phenomenon which involves the ability for an organism to maintain a stable internal environment despite fluctuations in the external environment. Homeostasis is important for the survival of living organisms as their cellular functions depend on it.
One of these environmental conditions is heat/hot temperature. Animals need to maintain a stable internal internal temperature despite the change in environment's. Animals do this by cooling down via various ways which include the following:
- Animals like apes, primates possess sweat glands like humans and hence cool down by SWEATING
- Animals like dog quickly exhale hot air and bring in cool air in a process called PANTING to cool down.
- Production of GOOSEBUMPS in animals help their hairs to stand in adverse weather conditions
Note that bird flap their wings in order to support flight and not perform an homeostatic process like cooling down.

The wave carries energy that causes molecules to move back snd forth. C. The wave carries a molecule in one direction until it collides with another molecule. D. The wave move through air and gains energy from the moving molecules that it touches.
Answer: A. The wave carries molecules of air away from the source of the sound .
Explanation:
The wave carries molecules of air away from the source of the sound describes a sound wave travels through air. So, the correct option is (A).
What are Waves?
When a disturbance in a medium occurs while carrying energy without a net movement of particles, this phenomenon is known as Wave. It can take the form of elastic deformation, a variation of pressure, electric or magnetic intensity, etc. There are some important parts in the Wave, they are- disturbance or variation which travelled through a medium.
There are three types of waves which is based on the orientation of particle motion and direction
Mechanical wavesElectromagnetic wavesMatter wavesWaves come in many shapes and forms which share some basic characteristic properties and behaviors can be distinguished from others based on several characteristics.
Thus, the wave carries molecules of air away from the source of the sound describes a sound wave travels through air. So, the correct option is (A).

To balance the inputs and outputs of cellular respiration, there should be the same number of carbon, oxygen, and hydrogen atoms on each side of the arrow.
a. True
b. False
Answer:
True
Explanation:
According to the law of conservation of mass, mass can not be created nor destroyed.
The implication of this is that the total mass on both sides of the reaction equation must be the same.
Thus, the number of atoms of each element on both sides of the reaction arrow must be the same.

Why are unrepaired gene mutations bad?
They make proteins with normal functions.
Their changes can be easily undone by DNA.
They affect the structure of proteins.
The affected chromosomes recoup and repair.
Answer:
They affect the structure of proteins.
Explanation:
A mutation is any change that occurs to the nucleotide sequence of a gene. A Gene is a segment of the genetic material (DNA) that encodes the protein needed for the growth and development of an organism. Hence, a change in the nucleotide sequence of a gene (mutation) will alter the structure of that protein that the gene encodes.
A protein function is attributed to its structure, hence, once the structure is altered because of unrepaired gene mutations bad, the protein loses functionality. This is why unrepaired gene mutations are bad.

During typical urination, a man releases about 400 mL of urine in about 30 seconds through the urethra, which we can model as a tube 4 mm in diameter and 20 cm long. Assume that urine has the same density as water, and that viscosity can be ignored for this flow. a. What is the flow speed in the urethra
Answer:
The flow speed in the urethra is 3.77 m/s
Explanation:
The flow rate or speed of a liquid is a measure of the volume of liquid that flows in a given amount of time.
Fluid flow rate, Q = area of the pipe or channel × velocity of the liquid
Q = A × v ; where Q is in m³/s or L/s; A is in m²; velocity, v = is in m/s
Also flow rate, Q = volume/time
volume, V, is in m³ and time is in seconds
therefore, V/t = A × v
v = At / V
Volume, V = 400 mL = 0.4 L = 4 × 10⁻⁴ m³
Area, A, of tube = πr², where r is radius in meters
r = 4 mm = 4 × 10⁻³ m
A = 22/7 × (4 × 10⁻³ m)²
therefore, v = {22/7 × (4 × 10⁻³ m)² × 30}/4 × 10⁻⁴ m³
v = 3.77 m/s
Therefore, the flow speed in the urethra is 3.77 m/s
