What might happen if there were no controls on the cell cycle?
Answer: When cell cycle is not controlled, it leads to still alive older cells and newly formed younger cells growing along with each other resulting in a tumor which is malignant, that is cancer. This can happen due to many factors as a result of genetic mutations.
Explanation:
A lack of control on cell cycle would cause older living cells to grow alongside younger living cells (newly formed), thereby, resulting in the formation of malignant cells (tumors) such as cancerous cells.
A cell cycle refers to an ordered sequence of events that takes place within a living cell as it grows and divide into two new daughter cells.
Basically, there are four (4) main stages in a cell cycle and these are:
Gap 1 (G1).Synthesis (S).Gap 2 (G2).Mitosis (M).The cell cycle is usually controlled and regulated so as to ensure living cells only divide as and when required by the body system of a living organism.
Hence, at each stage of a cell cycle, a set of conditions and control system determines whether or not a particular cell will continue into the next stage.
Generally, the cell cycle is controlled by cyclin-dependent protein kinases (Cdks) and regulated by subunits referred to as cyclins.
In conclusion, lack of control on cell cycle would cause older living cells to grow alongside younger living cells (newly formed), thereby, resulting in the formation of malignant cells (tumors) such as cancerous cells.

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.

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

2.) 19. Which of these processes is important in increasing genetic diversity in
organisms?
♡
Answer:
its either meiosis or mitosis i cannot remember which though
Explanation:
The process that is important in increasing genetic diversity in organisms is meiosis, and in this process, the genetic diversity is seen due to the genetic crossing over and the recombination.
What makes meiosis important for the organism?Meiosis is the process in which the parent cell makes the gametes that are haploid in nature; the male makes the sperm and the female makes the ovum in this process, and each of these gametes contains half of the genetic materials of the parent. Because meiosis results in genetic diversity in nature, it is important for the organism that produces offspring through sexual reproduction, and genetic diversity is seen in animals due to this process.
As a result, meiosis is an important process for increasing genetic diversity in organisms, and genetic diversity is visible during this process.

Diffusion: the Simple and the Facilitated
Diffusion is the movement of particles down their gradient. A gradient is any imbalance in concentration, and moving down a gradient just means that the particle is trying to be evenly distributed everywhere, like dropping food coloring in water. This is what happened when we made our granola - a bunch of separate ingredients came together and spread out across the whole mixture. We call this evening-out moving “downhill”, and it doesn’t require energy. The molecule most likely to be involved in simple diffusion is water - it can easily pass through cell membranes. When water undergoes simple diffusion, it is known as osmosis.
Movement Across a Membrane and Energy
There are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.

Diffusion of the Facilitated and Simple best describes a cell that uses passive transport to maintain homeostasis.
What is passive transportation?Passive transport is a type of membrane transport in which substances are moved across cell membranes without the use of energy. Unlike active transport, which uses cellular energy to move substances across cell membranes, passive transport uses the second law of thermodynamics to move substances across cell membranes. Passive transport is defined as the movement of a solute from one side of the cell membrane with a high electrochemical potential to the opposite side with a lower electrochemical potential. Passive transport requires no energy input. Diffusion, the movement of molecules from a high concentration area to a low concentration area, is an example of passive transport. Facilitated diffusion is mediated by carrier proteins and channel proteins.To learn more about passive transportation refer to:

How does waste filtered by kidneys leave the body? ( USA Test prep)
Answer:
The waste filtered by the kidneys leaves the body through the urine, which is expelled through the urinary tract.
Explanation:
The kidneys have the function of filtering the blood and cleaning it of any waste product, and for this purpose it produces urine.
Urine is an ultrafiltrate of the blood containing water, urea, uric acid, creatinine and ammonia, a product of cellular metabolism. As the urine is produced passes to the calyxes and renal pelvis, from where it will pass into the urinary tract to leave the body.
