The law of conservation of energy states that energy can neither be created nor be destroyed in a chemical reaction or biological system. Although, it gets transformed from one form to another.
What is an example of the law of conservation of energy?An example of the law of conservation of energy is as follows:
When you roll a toy car from a flat staircase, it will fall into the ground where the kinetic energy gets transferred into potential energy.This may be clearly understood by the fact when taking all forms of energy are present in the environment, the total energy of this isolated environment always remains constant. This reveals the law of conservation of energy.
Therefore, the law of conservation of energy is well described above.

Explanation:
what do each of the genes involved in maturity-onset diabetes of the young (mody) have in common?
The genes involved in maturity-onset diabetes of the young (MODY) have in common that they each play a role in metabolism of glucose, or insulin action and release.
What is metabolism?The group of chemical processes in organisms that maintain life is known as metabolism. The three primary functions of metabolism are the transformation of food's energy into cellular energy, the synthesis of proteins, lipids, nucleic acids, and certain carbohydrates, and the removal of metabolic wastes. Organisms may grow and reproduce, maintain their structures, and react to their environments thanks to these enzyme-catalyzed processes.
What do you understand by MODY?MODY, which stands for "Maturity-onset diabetes of the young," was previously known as Type 2 diabetes in adults because of how similar it behaved to Type 2 diabetes in young people. MODY is distinct from the juvenile form of diabetes in that it restricts the body's ability to manufacture insulin (Type 1 Diabetes).
Thus from above conclusion we can say that the genes involved in maturity-onset diabetes of the young (MODY) have in common that they each play a role in metabolism of glucose, or insulin action and release.

Hi can you help me come up with a hypothesis for a plan and design lab?
the problem statement was that Mary uses an enzyme based detergent for washing and noticed that it cleaned her clothes better in warm water rather than cold water.
Provide a hypothesis to the problem statment.
Answer:
The enzymes in the detergent have an optimal temperature closer to that of the warm water at which they have the greatest reaction velocity.
Explanation:
Enzymes function best at a specific pH and temperature. This is due to the chemical characteristics of the enzyme. In this case it was observed that the enzyme was able to clean better at a higher temperature. To test this you could measure the reaction velocities using a kinetic enzyme assay that uses a spectrophotometer to measure the absorbance of a sample over a period of time to record the change. The independent variable would be the temperature.

which is not true about disturbances? they occur only on short time scales. they are caused by natural events such as hurricanes. some are due to anthropogenic causes. they can cause complete destruction of an ecosystem.
The statement that is not true for disturbances is 'they can cause complete destruction of an ecosystem'.
Ecological disturbance is a non-biological or biological event or force that alters the spatial organization of organisms in the ecosystems they live in as well as their mortality. The nature of entire ecosystems as well as the organization of particular populations are significantly shaped by disturbance.
Even though disturbances frequently have a negative impact on the populations of native plants, animals, and other organisms in a given environment, they can also provide fugitive species a chance to enter and establish themselves in ecosystems where their biological communities once were excluded.

According to Charles Darwin, human traits and actions may be inherited and used for evolutionary goals. The correct option for given question is e
Charles Darwin introduced the Theory of Evolution by Natural Selection in his 1859 publication "On the Origin of Species." Darwin describes in his book how creatures change over generations through the inheritance of physical or behavioral features. As illustrated by one of the Galapagos finches Darwin studied and the form of its beak, the theory's central principle is that features can change within a population.
The theory holds that individuals who have traits that make it simpler for them to adapt to their environment will help them survive and have more offspring, who will inherit those traits. People that are less flexible are less likely to survive and pass those traits on.

The water molecule its going to break and its OH group attaches to the phosphate that is removed from the ATP.
What is hydrolysis?Hydrolysis is when a water molecule reacts with another macromolecule and it hydrates. What happens then is that the water molecule splits and releases an OH and the other part of the H2O is going to join the molecule forming part of the new chemical bond.
In ATP hydrolysis, the chemical bonds of ATP, which are high-energy bonds, are broken, resulting in the formation of ADP and an inorganic phosphate, which is to which the OH binds.
ATP hydrolysis occurs when energy is needed for a reaction, since ATP bonds have a lot of energy. It is used in many processes in the body, such as muscle contraction, transport of substances against a gradient.

the lungs do not normally collapse because of group of answer choices their characteristic elastic recoil both surfactant and intrapleural pressure none of the choices are correct intrapleural pressure surfactant
The lungs do not normally collapse because of both surfactant and intrapleural pressure.
The two spongy, pinkish-gray organs in your chest are called lungs. Air enters your lungs when you inhale (breath), and the oxygen in that air travels to your blood. A waste gas called carbon dioxide travels from your blood to your lungs at the same time and is exhaled (breathed out).
The pressure drop lowers the intrapulmonary pressure as well, which causes the lungs to open up and take in more air. This action is the opposite after the timer expires. The pleural cavity's negative pressure acts as a suction to prevent the lungs from collapsing.
The lung cells secrete surfactant, which distributes throughout the alveolar tissue. By reducing surface tension, this chemical facilitates breathing by preventing the alveoli from collapsing following exhalation.

The ratio of x1/x2 after 10 h of batch growth would be 2:1. The batch growth of the mixed cultures should last for 20 h in order to obtain x1/x2.
We calculate this using,
a) Rate
N= N0ekt
For each bacteria we have to find out K so first bacteria with doubling time 2 hour
Assume there were 100 bacterias then after 2 hours there will be 200 bacterias
so N = 200 , N0=100 and t=2 hours
200 = 100*ek*2
200/100 = e^2K
e^2K = 2
Taking ln on both sides
2K = ln 2
K = ln2/2
=0.34657
The equation for bacteria X1
N0= Ne0.346t
For bacteria X2 K= ln2/4 ( because only difference here is the doubling time) =0.17328
So the equation for X2
N0= Ne0.173t
a) X1/X2 after 10 hours so t = 10
Ne0.346t / Ne
0.173t=e0.346t / e0.173t
= e0.346*10 / e0.173*10
= 31.817 / 5.64
=5.6413
b) X1 / X2= 10
e0.346t / e0.173t =10
Taking ln on both sides
ln ( e0.346t / e0.173t )= ln 10
ln e0.346t- ln e0.173t = ln 10
0.346t- 0.173t = 2.302
t ( 0.346- 0.173 ) = 2.302
t = 2.302/ ( 0.346 - 0.173)

After fermentation inhibition, muscle contraction could continue for a while.
What was his evidence?
It was shown by Lundsgaard that muscles still contract when in glycolysis, the formation of lactic acid is inhibited by the use of iodoacetate pharmacologically.
He also showed that during muscle contraction, pcr gets broken down and the breakdowns extent is proportional to tension created. On the idea of those experiments, Lundsgaard cautioned that the breakdown of PCr changed into the number one energy‐presenting response and this is what initiated the lactate‐forming reactions which regenerated PCr.
Therefore, for contraction, glycogen to lactate conversion is not necessary.
