In genetics, a mutation is a change that occurs in the DNA sequence of an individual. This change can affect the genetic information passed from one generation to another. Mutations can occur spontaneously, or they can be caused by environmental factors such as radiation or exposure to chemicals. In human genetics, mutations can lead to genetic disorders or predisposition to certain diseases. Some mutations may have no effect at all, while others may have a significant impact on an individual's health and well-being.

Answer:

Mutations are serious malfunctions to the human genetics. An example is cystic fibrosis. A mutation in a single gene causes the body to produce thick, sticky mucus that clogs the lungs and blocks ducts in digestive organs.

A geneticist hypothesizes that half of a given population will have brown eyes and the remaining half will be split evenly between blue- and green-eyed people. In a random sample of 60 people from this population, the individuals are distributed as shown in the table below.

Brown Eyes

Green Eyes

Blue Eyes

34

15

11

What is the value of the statistic for the goodness of fit test on these data?

a. At least 1, but less than 10

b. Less than 1

c. At least 10, but less than 20

d. At least 20, but less than 50

e. At least 50

According to the hypothesis, we would expect 30 people to have brown eyes, and the remaining 30 to be split evenly between green and blue eyes, with 15 people in each category.

However, in the sample of 60 people, there were 28 with brown eyes, 18 with green eyes, and 14 with blue eyes. This deviation from the expected distribution could be due to random chance, or it could indicate that the actual population distribution is different from what the geneticist hypothesized. Further research would be needed to determine the cause of this discrepancy. Based on the given information, the geneticist's hypothesis states that in a given population, 50% will have brown eyes, while the remaining 50% will be split evenly between blue-eyed and green-eyed individuals, meaning 25% will have blue eyes and 25% will have green eyes. In a random sample of 60 people, this distribution would be expected as follows:

Brown Eyes: 0.5 * 60 = 30 people
Green Eyes: 0.25 * 60 = 15 people
Blue Eyes: 0.25 * 60 = 15 people

So, according to the geneticist's hypothesis, in a random sample of 60 people, we would expect 30 to have brown eyes, 15 to have green eyes, and 15 to have blue eyes.

During ventricular contraction, the status of the atrioventricular valves is The mitral and tricuspid valves both are closed. (D)

The atrioventricular valves, which include the mitral and tricuspid valves, prevent the backflow of blood from the ventricles to the atria during ventricular contraction.

When the ventricles contract, the pressure inside the ventricles increases, causing the mitral and tricuspid valves to close. This prevents the backflow of blood into the atria and ensures that the blood flows out of the ventricles through the aortic and pulmonary valves to the rest of the body.

In summary, during ventricular contraction, the mitral and tricuspid valves both are closed to prevent the backflow of blood into the atria.

The correct sequence of events is:

Deposition of limestones: The limestone layer was deposited first, at the bottom of the cliff.

Deposition of sandstones: The sandstone layer was deposited on top of the limestone layer.

Intrusion of magma: The magma intrusion occurred after the sandstone layer was deposited.

Formation of metamorphic rocks: The metamorphic rocks were formed when the sandstone layer was subjected to heat and pressure.

The diagram shows that the magma intrusion cut through the sandstone layer, which means that the intrusion must have occurred after the sandstone layer was deposited. The metamorphic rocks are also found on top of the sandstone layer, which means that they must have formed after the sandstone layer was deposited.

Because it gives a clearer picture of the relative change in mass over time, computing percentage change on mass rather than change in mass is seen to be a more reliable method.

The difference between two values is expressed as a percentage of the original value using the measure of percentage change. Comparing changes in values over time is a common task in statistics, economics, and finance. By dividing the difference between two values by the original value and multiplying by 100, one may determine the percentage change. Regardless of the size of the changes, this metric offers a consistent way to compare results. When comparing data that are measured in different units or when the variables being compared have distinct scales, percentage change is very helpful. It is a straightforward yet effective technique for discovering patterns and trends in data.

Photosystem PS1 is a photosystem found in the thylakoid membranes of chloroplasts in plants and other photosynthetic organisms.

What exactly are photosynthetic organisms?

Photosynthetic organisms are organisms that can produce their own food through the process of photosynthesis. This process involves the use of light energy to convert carbon dioxide and water into glucose (sugar) and oxygen. Photosynthetic organisms include plants, algae, and some bacteria.

Photosystem PS1 is the primary photosystem in plants and other photosynthetic organisms. It is composed of two membrane-bound proteins, called photosystems, that contain light-harvesting complexes and a reaction center. The light-harvesting complexes absorb energy from sunlight and direct it to the reaction center, where it is used to produce ATP and NADPH, the molecules needed for photosynthesis. The products of photosystem PS1 are then used to drive the second photosystem, PS2, which produces the end products of photosynthesis.

One of the problems that occur as a consequence of CFC pollution is increasing skin cancer in humans.

CFCs (chlorofluorocarbons) are synthetic compounds that were commonly used in various industrial and consumer applications. When released into the atmosphere, CFCs can deplete the ozone layer, which acts as a protective shield against harmful UV radiation from the sun. With a thinner ozone layer, more UV radiation reaches the Earth's surface, increasing the risk of skin cancer in humans. Prolonged exposure to UV radiation can lead to various types of skin cancer, including basal cell carcinoma, squamous cell carcinoma, and melanoma.

C Es el tejido formado por fibras musculares que tiene movimiento involuntario y forma órganos internos

Explanation:

El tejido muscular es un tipo de tejido formado por células contráctiles especializadas llamadas miocitos. El tejido muscular se divide en tres clases diferentes: tejido muscular esquelético, tejido muscular cardíaco y tejido muscular liso. El tejido muscular esquelético es aquel que se mueve de acuerdo a la voluntad del individuo, cuyas células son multinucleadas y poseen una gran cantidad de mitocondrias. El tejido del músculo cardiaco es involuntario y está formado por células uninucleadas (miocardiocitos) las cuales componen las paredes del corazón. Finalmente, el tejido muscular liso también es involuntario y está formado por células uninucleadas con el núcleo en el centro. Las células musculares lisas contienen un citoplasma con haces de filamentos de actina y miosina los cuales están organizados más irregularmente que en fibras musculares estriadas. Este tipo de tejido (músculo liso) se localiza en las paredes de los órganos internos o víseras como, por ejemplo, el tracto gastrointestinal, conductos de glándulas, el sistema urinario, etc., y en los vasos sanguíneos.
