¿Qué sucede con un pasajero que está de pie en un autobús cuando este inicia el
movimiento?
¿Por qué sucede eso?
Answer:
El pasajero se mueve hacia atrás.
Explicación:
Cuando el autobús comienza a moverse hacia adelante, el pasajero que está parado en un autobús se mueve hacia atrás debido a la inercia. La inercia es una propiedad en la que un cuerpo resiste cualquier cambio en su estado de reposo o movimiento. Al principio, el pasajero está en reposo, por lo que cuando el autobús comienza a moverse en la dirección de avance, el pasajero se mueve en la dirección de retroceso para permanecer en reposo debido a la propiedad de la inercia. Por eso el pasajero se mueve hacia atrás.

According to the Punnett Square shown above
A.
there is a 50% probability that an offspring will have brown eyes and a 50% probability that an offspring will have blue eyes.
B.
there is a 75% probability that an offspring will have blue eyes and a 25% probability that an offspring will have brown eyes.
C.
there is a 75% probability that an offspring will have brown eyes and a 25% probability that an offspring will have blue eyes.
D.
there is a 100% probability that an offspring will have one brown eye and one blue eye.
Answer:
C. There is a 75% probability that an offspring will have brown eyes and a 25% probability that an offspring will have blue eyes.
Explanation:
Note that the brown eyes is the dominant trait, denoted by B, while blue eyes is the recessive trait, denoted by b. In all cases of the Punnett square, if there is a dominant and recessive trait, the dominant trait will always come out on top.
The given Punnett square:
[tex]\left[\begin{array}{ccc}&B&b\\B&BB&Bb\\b&Bb&bb\end{array}\right][/tex]
Note that there are 3 options (BB, Bb, Bb) respectively, in which there is the dominant trait B (brown eyes). Only in one case is there only the recessive trait b (blue eyes), or a 1/4 chance of obtaining blue eyes. Therefore, there is a 3/4 chance of obtaining a brown eye:
C. There is a 75% probability that an offspring will have brown eyes and a 25% probability that an offspring will have blue eyes.

How gamete formation leads to genetic variation.
Answer:
The process that produces gametes is called meiosis. During meiosis, homologous chromosomes (1 from each parent) pair along their lengths. ... At each chiasma, the chromosomes break and rejoin, trading some of their genes. This recombination results in genetic variation.
Answer:
Explanation:
During fertilisation, 1 gamete from each parent combines to form a zygote. Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote.

Phalloidin is a toxin from a toadstool (mushroom). You are studying actin dynamics and the effect of phalloidin. You add G-actin and ATP to a test tube and allow the reaction to come to equilibrium. This produces the light scattering plot below. When you add phalloidin, what will happen to the line?
Answer:
Dissociation of actin subunits occurs.
Explanation:
When we add phalloidin to a solution containing G-actin, the phalloidin binds to actin filaments more tightly as compared to actin monomers which leads to a decrease in the constant rate of dissociation of actin subunits from the ends of the filament. This dissociation stabilizes the actin filaments through the prevention of filament depolymerization. So we can conclude that addition of phalloidin to actin leads to stabilizing of actin filaments.

Using examples where supportive, discuss the following statement, "From vaccinations and diagnostics, to explaining the root causes of many diseases, immunology is having a profound impact on life today"
Answer:
Yes.
Explanation:
Yes, immunology is having a profound impact on life today because this immunology provides information about the study of immune system. To find out the root cause of many disease, the study of immune system and its responses against many diseases are important in order to counter the infection. The immune system protects us from infection through various defense mechanism. If the immune system is not working properly, it can result in disease, such as autoimmunity, allergy and cancer etc.

Answer: Structural adaptations are physical features of an organism like the bill on a bird or the fur on a bear. Other adaptations are behavioral. ... Adaptations usually occur because a gene mutates or changes by accident! Some mutations can help an animal or plant survive better than others in the species without the mutation.
Explanation:
During the normal cardiac cycle, the bicuspid valve opens when: the pressure in the right ventricle is greater than in the right atrium b. the pressure in the right atrium is greater than in the right ventricle c. the pressure in the left atrium is greater than in the left ventricle d. the pressure in the left ventricle is greater than in the left atrium e. the pressure in the right ventricle is greater than in the pulmonary artery
Answer:
b. the pressure in the right atrium is greater than in the right ventricle
Explanation:
A bicuspid valve is an aortic valve that only has two leaflets, instead of three. The function of aortic valve is to regulates blood flow from the heart into the aorta. The valve opens and closes because of pressure differences. The opening of the valve occurs when the pressure is greater in the left atrium than ventricle whereas, closing happens when there is greater pressure in the left ventricle than atrium so we can conclude that the pressure in the right atrium is greater than in the right ventricle.

You are studying a disorder that is based on the genetic composition at three loci. Assume that a dominant allele at any locus adds 5 units of risk for the disorder and that a recessive allele at any locus adds 3 units of risk for the disorder. Individuals with 26 or more units of risk develop the disorder. The environment does not affect the presence or absence of this disorder. How many risk units will be present in an individual of genotype AABbcc
Answer:
24
Explanation:
Given that:
At either locus, the expression of the dominant allele increases the risk by 5 units.
The assigned genetic sequence "AABbcc" has three dominant alleles, implying that it increases risk by 15 units.
At any locus, the expression of the recessive allele increases the risk by three units. The assigned genetic sequence "AABbcc" has three recessive alleles, which means it increases the chance by 9 units.
In an individual with the genotype AABbcc, the total number of risk units is = 15+9 = 24. This implies that the person does not develop the disease).
Which of the following lists accurately represents the increasing complexity of genetic materials?
O base pairs, DNA, gene, chromosome, cell
O DNA, base pairs, gene, chromosome, cell
O gene, chromosome, cell, base pairs, DNA
gene, chromosome, DNA, cell, base pairs
The correct answer is A. Bases pairs, DNA, Gene, Chromosome, Cell.
Explanation
Nitrogen bases are chemical compounds that compose DNA and RNA, in the case of DNA the bases are adenine, thymine, guanine, and cytosine, while RNA is made up of uracil, adenine, guanine, and cytosine. Additionally, DNA makes up genes, which are structures that store information that is passed on to offspring. Also, genes are organized to form chromosomes (more complex structures) of genetic information. Finally, there are cells, in them are chromosomes, fundamental for the reproduction of an organism. Therefore, the correct answer is A. Bases pairs, DNA, Gene, Chromosome, Cell.
