Answer:

Una mutación es el cambio al azar en la secuencia de nucleótidos o en la organización del ADN (genotipo) de un ser vivo,1​ que produce una variación en las características de este y que no necesariamente se transmite a la descendencia. Se presenta de manera espontánea y súbita o por la acción de mutágenos. Este cambio estará presente en una pequeña proporción de la población (variante) o del organismo (mutación). La unidad genética capaz de mutar es el gen, la unidad de información hereditaria que forma parte del ADN.2​

En los seres pluricelulares, las mutaciones solo pueden ser heredadas cuando afectan a las células reproductivas.3​ Una consecuencia de las mutaciones puede ser, por ejemplo, una enfermedad genética. Sin embargo, aunque a corto plazo pueden parecer perjudiciales, las mutaciones son esenciales para nuestra existencia a largo plazo. Sin mutación no habría cambio, y sin cambio la vida no podría evolucionar.

A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division.

Explanation:

Br₂(g) and K(l) species are made at the anode and cathode, respectively.

Molten lead bromide, PbBr 2(l), is an electrolyte.

During electrolysis: Pb 2+ ions gain electrons at the cathode and become Pb atoms.

Br - ions lose electrons at the anode and become Br atoms, which pair up to form Br 2 molecules.

Thus, Br₂(g) and K(l) species are made at the anode and cathode, respectively.

The function of the basilar membrane, hair cells, and tectorial membrane are as follows: The sound waves cause the basilar membrane to vibrate first. The hearing receptors are embedded in the hair cells. The structure that bends the hearing receptors but does not vibrate itself is the tectorial membrane. The hearing receptors are connected to the basilar membrane by supporting cells. As a result of this vibration, hair cells are bent. Hearing receptors are called hair cells.

The cochlea is an organ of the inner ear that is shaped like a snail shell. It contains tiny hair cells that are responsible for picking up sound vibrations and transforming them into nerve signals that can be interpreted by the brain.

The cochlea contains a fluid-filled cavity that is set in motion by sound vibrations. The basilar membrane is a structure that runs along the length of the cochlea and separates the fluid-filled cavity into two chambers. When sound vibrations enter the cochlea, they cause the basilar membrane to vibrate.

This vibration causes the hair cells, which are embedded in the basilar membrane, to bend. The tectorial membrane, which is located above the hair cells, does not vibrate but is responsible for bending the hair cells when the basilar membrane vibrates. The bending of the hair cells causes electrical signals to be sent to the brain, which are then interpreted as sound.

Hence, the sound waves cause the basilar membrane to vibrate first. The hearing receptors are embedded in the hair cells. The structure that bends the hearing receptors but does not vibrate itself is the tectorial membrane. The hearing receptors are connected to the basilar membrane by supporting cells. As a result of this vibration, hair cells are bent. Hearing receptors are called hair cells.

Cross-pollination with two parental (P) plants produced the F1 generation,  Self-pollination on F1 plants produced the F2 generation, which had 75% purple flowers & 25% white blooms.

Mendel next crossed these plant lines for purebreeding and noted the characteristics of the hybrid offspring. The entire crop of first-generation (F1) hybrids, he discovered, resembled one of the parent plants. For instance, all the offspring of a hybrid between purple and white flowers were blue (not pink, as blending would have predicted).

A dihybrid cross is made up of two people who have two features that are regulated by two different genes. Gregor Mendel's observation of pea plants which were either round or wrinkled, yellow or green, gave rise to the concept of a dihybrid cross.

Ironically, Oersted made his discovery during a lecture where he was trying to show to students that electricity and magnetism are in fact not related. Using a compass and a wire with current, he showed that the needle of the compass pointed toward the earth's north pole. However, a student accidentally found out that moving the wire made the compass needle turn, which prompted Oersted to rethink his ideas.

17.

A magnetic field is largely affected by temperature, since a higher temperature causes the molecules in the wire to jiggle faster, and make the flow of electrons more difficult. The field is also affected by the material that the wire is made out of, because this once again impacts the conductivity of it and how much electricity can flow through it.

Explanation:

The part of the limbic system that is associated with pleasure and addictive behavior is the mesolimbic pathway.

This pathway is involved in the release of dopamine, a neurotransmitter that is often referred to as the "feel-good" chemical.

When dopamine is released in this pathway, it leads to feelings of pleasure and reward.

However, when this pathway is activated repeatedly, such as in the case of drug addiction, it can lead to the development of addictive behavior.

This is because the brain becomes accustomed to the release of dopamine and begins to crave it, leading to a cycle of addiction.

Understanding the role of the mesolimbic pathway in addiction is crucial for developing effective treatments for those struggling with addiction.

 The step-by-step approach helps maintain the equality of atoms on both sides of the equation, satisfying the law of conservation of mass.

Problem: Balance the following chemical equation: Fe + HCl -> FeCl3 + H2

Solution:

Step 1: Write down the given chemical equation.

Fe + HCl -> FeCl3 + H2

Step 2: Count the number of atoms on each side of the equation.

On the left-hand side (LHS):

Fe: 1 atom

H: 1 atom

Cl: 1 atom

On the right-hand side (RHS):

Fe: 1 atom

Cl: 3 atoms

H: 2 atoms

Step 3: Start by balancing the most complex or compound with the highest number of atoms. In this case, FeCl3 is the most complex compound.

Let's balance FeCl3 first:

FeCl3 has one Fe atom and three Cl atoms. To balance the Cl atoms, we need three HCl molecules on the LHS, so let's add 3 in front of HCl in the equation:

Fe + 3HCl -> FeCl3 + H2

The equation now looks like this:

Fe + 3HCl -> FeCl3 + H2

Step 4: Count the atoms again.

On the LHS:

Fe: 1 atom

H: 3 atoms

Cl: 3 atoms

On the RHS:

Fe: 1 atom

Cl: 3 atoms

H: 2 atoms

Step 5: Now, balance the hydrogen atoms. There are three hydrogen atoms on the LHS and only two on the RHS. To balance them, we need to add another H2 molecule on the RHS:

Fe + 3HCl -> FeCl3 + 2H2

The equation now looks like this:

Fe + 3HCl -> FeCl3 + 2H2

Step 6: Count the atoms one more time.

On the LHS:

Fe: 1 atom

H: 3 atoms

Cl: 3 atoms

On the RHS:

Fe: 1 atom

Cl: 3 atoms

H: 4 atoms

Step 7: Finally, the equation is balanced for all atoms.

The balanced equation is:

Fe + 3HCl -> FeCl3 + 2H2

In this equation, both sides have one iron (Fe) atom, three chlorine (Cl) atoms, and four hydrogen (H) atoms, satisfying the law of conservation of mass.

Now let's check the balanced equation to ensure it is correct. The number of atoms on both sides of the equation is equal, indicating that mass is conserved in the reaction.

Response to other students:

Student 1: Great job on balancing the equation! However, I noticed that you added an extra coefficient in front of HCl. It should be 3HCl instead of 4HCl to balance the atoms correctly. Keep up the good work!

Student 2: Your balanced equation is correct! Well done. However, I have a question. Can you explain why we balance the most complex compound first? Is there a specific reason for that?

To Student 2:

Thank you for your question! Balancing the most complex compound first is a common approach because it often involves more atoms, making it easier to balance other atoms afterward. By starting with the most complex compound, we can ensure that the equation is balanced in terms of the elements it contains.

Once the most complex compound is balanced, we can focus on balancing the remaining atoms, typically starting with the atoms that appear in only one compound on each side. This step-by-step approach helps maintain the equality of atoms on both sides of the equation, satisfying the law of conservation of mass.
