Explanation:
Because we always seek to make sense of any perceived stimulus to better understand the reality that surrounds us and act before it. Through perception we process information from the senses, with which the brain builds and tries to give meaning to those stimuli that reach it. However, each person captures, selects and organizes sensory stimuli differently and, therefore, arrives at different interpretations and responses when solving a problem, in which memory and experience also form a fundamental role. Thus, differences between perceptions help explain how people interpret the environment and why they behave differently in the same situation. For example, when we recognize a specific object, an action can be initiated, in which a motor activity is propitiated in response to that recognition, and which can be different in each person.
The speed of sound is faster in the air than in the water.
The speed of sound does not change as it moves through the air or water.
The speed depends on how loud you yell.
The correct answer is: The speed of sound is faster in the water than in the air.
The speed of sound is different between those two mediums because they have different densities. Since, water is denser than air, more energy is required to generate a wave but once it stars, it travels faster than it would do in air. Sound waves’ travel can be presented by particles that transmit the energy one to another as they bump. The sound speed is lower in the air (than in water) because particles are far apart, so they travel further before they collide.

Answer: The correct answer for the blank is -
A) competition.
The predator population captures, kills and consume the prey (such as Lion eats leopard and other animals) Due to this, the size of prey population is reduced. This will eventually lead to decrease in competition for various resources (such as food, shelter, mates) within the prey population.
no it wasnt the answer was A
If all of the individual in a generation receives one dominant allele and one recessive allele, then they will all show the dominant trait.
If they are bred, they will pass on the dominant allele to some of their offspring and recessive allele to others.
If an offspring receives two recessive alleles, it will show the recessive trait and therefore it will reappear.
When two true-breeding or homozygous individuals for dominant and recessive traits are crossed, the resultant is always a dominant trait. The recessive character appears in the following generation when the F1 progeny is self-crossed due to independent segregation and random fusion of gametes.
Further Explanation:
Consider Mendel's experiment on a pea plant in which he used the trait of height as tall and short. On self-pollinating the tall plants, the resulting progeny were all tall while when self-pollination was done for short plants, the resultants were all short. It was found that when true-breeding short (t) plants are bred with the true breeding tall (T) plants, the offspring results in all tall plants in the F1 generation. When this progeny is self-crossed, the F2 generation results in both tall and short plants in a 3:1 ratio.
Mendel stated that the traits are controlled by genes that are present in pairs of alleles. Each parent contributes the alleles in the pair. Allele 'T' is received from a tall parent while short parent contributes to allele’t’ and they together produce a tall plant. This is because the 'T' allele suppresses the expression of’t’ allele because of its dominant nature. Therefore,’t’ is a recessive allele, and 'T' is a dominant allele.
Cross between true-breeding tall (TT) and short (tt) plant:
Parents: TT x tt
Gametes: T x t
Progeny: Tt (tall, F1 generation)
When F1 generation is self crossed:
Parents: Tt x Tt
Gametes: T, t x T, t
Progeny: TT, Tt, Tt, tt
In the F1 generation,the recessive trait (short plant) was suppressed because of the dominance of the 'T' allele over the’t’ allele. In the following generation, the recessive trait reappeared because of the independent segregation of gametes and their random association with each other.

B. Mismatch repair
C. Direct repair by methyltransferases
D. Nucleotide excision repair
Answer:
The correct answer is B. Mismatch repair
Explanation:
Mismatch repair pathway recognizes the mismatched base pair that incorporated during DNA replication and then excise that incorrect base. After excision, it repairs the DNA.
The mismatched daughter strand is distinguished from the parent strand by mismatch repair system as the parent strand is methylated at some bases but the daughter strand is not methylated.
Three proteins help in mismatch repair MutH, MutL, MutS. Mut H and Mut S recognize the mismatch, Mut H excise the unmethylated strand from 5' side. Then helicase and exonuclease enzymes clave the segment from cleavage site to beyond the mismatch base.
The gap created by this action is filled by DNA polymerase and sealed by enzyme DNA ligase.
The 'Mismatch repair' pathway corrects mistakes when an incorrect nucleotide has been incorporated into a DNA sequence and DNA polymerase fails to recognize it. This pathway involves several proteins that recognize the error, excise the incorrect sequence, and re-synthesize the correct sequence.
When DNA polymerase fails to recognize that an incorrect nucleotide has been incorporated, resulting in a mismatch, the Mismatch repair pathway is in charge to correct this mistake. This system detects and repairs erroneous insertion, deletion, and mis-incorporation of bases that can arise during DNA replication and recombination, as well as repairing some forms of DNA damage. This process involves several proteins including MutS, MutL, and MutH. They recognize the error, excise the incorrect sequence and then re-synthesize the correct sequence using the original undamaged DNA strand as a template. The 'Mismatch repair' is a crucial mechanism to maintain the integrity of genetic information.
