Which of the following can be inferred from the diagram above that shows the dependence of potential Energy on the Internuclear distance between two atoms?
A)The atoms form a bond with a bond length of 25 pm
B)The atoms form a bond with a bond length of 75 pm
с)The net force between the atoms is attractive at 25 pm
D)The net force between the atoms is attractive at 75 pm
Answer:
A)The atoms form a bond with a bond length of 75 pm
Explanation:
The Morse curve is a plot of potential energy against internuclear distance between two atoms.
When two atoms are far apart, the bond energy is zero, this means that there is no significant interaction between the both atoms. Hence, when two atoms are positioned at infinite distance from each other, they do not interact with each other appreciably. At internuclear distance within the range of atomic diameter, attractive forces predominate between atoms. At shorter distances repulsive forces predominate and the energy of system is quite high. The minimum point in the plot of a Morse curve represents equilibrium between attractive and repulsive forces.
The internuclear distance that corresponds to this minimum point is known as the equilibrium bond length.
For the plot shown in the question, the minimum point occurs at an internuclear distance of 75pm. This corresponds to the bond length of the system.

Escribe lo que piensa de la siguiente suposición si es cierta o no: " Todas las semillas de una fruta sobrevivirán, se convertirán en adultas y tendrán sus propias frutas. " Describa de si esta suposición es verdadera para otros organismos como las bacterias y animales además de las plantas)
Answer:
Esta suposición no es realista, muchas de las semillas no llegarán a la etapa adulta y por lo tanto no podrán generar nueva progenie
Explanation:
Acorde a la teoría de la evolución por selección natural planteada por Darwin, solamente aquellos organismos que se encuentren mejor adaptados al ambiente en el que viven podrán sobrevivir y de este modo perpetuar sus genes en la progenie. Este es un principio que aplica a todos los tipos de organismos vivientes (es decir, plantas, animales, bacterias, etc). Darwin definió a este proceso evolutivo como 'descendencia con modificación', donde aquellos organismos que se encuentren mejor adaptados a su ambiente transmitirán sus rasgos a la descendencia, mientras que aquellos que no se encuentren suficientemente adaptados no podrán sobrevivir.

Identify the force used on your arm when you walk a dog on a leash and it tries to chase something
Friction
Gravity
Strong pull
Weak push
The force used on your arm when you walk a dog on a leash and it tries to
chase something is known as Strong pull.
Strong pull is defined a physical force which is usually aggressive or
coercive and it involves the movement in a particular direction due to
different factors or reasons.
The Dog in the example has a leash on and applies a force in the direction of
the thing it wants to chase which is a perfect example of a strong pull.

in what ways is ATP like a fully charged battery?
Answer:
ATP ATP can be compared to a fully charged battery because both contain stored energy, whereas ADP resembles a partially charged battery. Releasing Energy From ATP The energy stored in ATP is released when ATP is converted into ADP and a phosphate group.
Explanation:
The ATP molecule is comparable to a battery that can be recharged. It is ATP when ultimately charged. It's ADP when it's worn out. When the battery runs out, it is simply recharged rather than discarded.
What is ATP?A vital "energy molecule" in all living things is adenosine 5′-triphosphate, also known as ATP and typically written without the 5′-. In particular, it is a coenzyme that transfers cells' energy by liberating its phosphate groups when it interacts with enzymes like ATP triphosphatase. The molecule comprises an adenine bicyclic system, a furanose ring, and a triphosphate chain.
The discovery of ATP was announced in 1929 by two research teams. It was isolated from mammalian muscle and liver by Cyrus H. Fiske and Yellapragada Subbarow at Harvard Medical School (Boston). Karl Lohmann discovered it in muscle tissues while working for the Kaiser Wilhelm Institutes in Berlin and Heidelberg.
Over the next 15 years, ATP separation from other sources came next. In 1987, Koscak Maruyama of Chiba University (Japan) provided a thorough analysis of ATP's discovery and structural elucidation.
Therefore, ATP is like a rechargeable battery because it can be recharged and discharged.

Check Some flatworms reproduce through fragmentation. What is a disadvantage of this method?
1.) It is a very slow process relative to sexual reproduction.
2.) It is a process that leads to lower genetic diversity than sexual reproduction
3.) It is a process that does not result in many offspring relative to sexual reproduction
4.)It is a much more complex process than sexual reproduction.
Answer:
it is a process that leads to lower genetic diversity than sexual reproduction
Following are the disadvantages of this method:
It is a very slow process relative to sexual reproduction.It is a process that leads to lower genetic diversity than sexual reproduction.Fragmentation is a method of reproduction that occurs when an organism breaks into smaller pieces, which then grow into new individuals. While this process can be efficient in certain circumstances, it has several disadvantages compared to sexual reproduction. One disadvantage is that it is a very slow process relative to sexual reproduction. This is because it takes time for the fragments to grow and develop into new individuals, and there may be many steps involved in this process.
Additionally, fragmentation leads to lower genetic diversity than sexual reproduction, because the offspring are identical to the parent organism, rather than being the result of a mixing of genetic material from two different parents. These factors may make fragmentation a less effective method of reproduction in some circumstances.

Explain why diversity is important for the survival of a species?
Answer:
The importance of genetic diversity. More specifically, genetic diversity can be a species natural defence system against disease and survival even under extreme weather conditions but more importantly, genetic diversity can help weed out unfavourable traits in species which maximises opportunities for thriving in any environment². hoped it helped.
Explanation:
Increased genetic diversity leads to increased chance of species survival. Species with a limited variety of phenotypes and where all members of the species are similar to one another have a smaller chance of coping with environmental variability compared to a species with greater diversity.
