When inhaled, crystalline silica can cause scar tissue to form on what organs?

Answers

Answer 1

Crystalline silica is a natural compound in the earth's crust and is a basic component of sand and granite. Silicosis is an incurable disease of the lungs caused by breathing crystalline silica dust. This dust can cause scar tissue to form in the lungs.

Answer 2

Answer:

lungs

Explanation:

Inhaling silica causes permanent damage to the lungs and can lead to death.

When people inhale crystalline silica, the tissue present in the lungs reacts and develope fibrotic nodules. It also scars the lung tissue around the trapped silica particles. If these fibrotic nodules grow large, breathing becomes difficult.

Breathing in crystalline silica dust can cause a severe even fatal case called silicosis. When silica enters into the lungs, it causes the formation of scar tissue and makes it difficult for the lungs to take oxygen. There is no cure to silicosis.

Therefore, Inhaling crystalline silica affects the lungs.

determine the genotype of the parents if the father is blood type A, the mother is blood type B, the daughter is blood type O, one son is blood type AB, and the other son is blood type B

Answers

Father: IAi

Mother: IBi

Final answer:

The father with blood type A and the mother with blood type B have genotypes AO and BO, respectively. This is evidenced by their children with blood types O, AB, and B, which indicates that both parents carry an O allele necessary for blood type O and alleles A and B for the AB blood type, demonstrating co-dominance in ABO blood group inheritance.

Explanation:

Genotype Determination Based on Blood Types

If the father's blood type is A and the mother's blood type is B, and they have children with blood types O, AB, and B, we can determine their genotypes. Blood type A can have the genotype AO or AA, and blood type B can have the genotype BO or BB. However, because they have a daughter with blood type O, which is recessive and has the genotype ii, both parents must carry the O allele. Therefore, the father's genotype must be AO, and the mother's genotype must be BO. Moreover, the presence of a son with blood type AB confirms that both parents must have provided an A and a B allele, respectively, indicating the co-dominance of these alleles. Thus, the parents' genotypes are determined to be AO for the father and BO for the mother, as these genotypes can produce offspring with all possible ABO blood types.

The information provided indicates that ABO blood group inheritance works on a co-dominance basis where A and B alleles are dominant over O. For the couple in question, they can indeed produce children with all four blood types (A, AB, B, and O) given their AO and BO genotypes.

List the three bacterial species in order of their increasing fastidiousness

Answers

The term fastidiousness refers to the complexity of an organism's nutritional requirements. A fastidious microorganism will only grow if the culture medium provides the necessary nutrients. This table provides the readings on the optical density from bacterial cultures. This reading gives an indication of the concentration of the bacteria in the culture; the higher the concentration of bacteria, the greater scatter of light and the higher value of optical density. Yeast extract broth, nutrient broth and glucose broth are culture media which are enriched with more nutrients. In all these three media, S.mitis had the lowest optical density, meaning the lowest concentration. We can conclude that S.mitis is the most fastidious microorganism of the three. Then comes A.faecalis and the least fastidious of the three is E.coli.

In order of increasing fastidiousness, the list of bacterial species starts with Escherichia coli, followed by Staphylococcus aureus, and ends with Micrococcus luteus, with E. coli being the least demanding and M. luteus the most demanding in terms of growth requirements.

The term fastidiousness in biology refers to the level of nutritional and environmental specificity that bacteria require for growth. To list bacterial species in order of their increasing fastidiousness is to arrange them from the least demanding to the most demanding in terms of the growth conditions they require. Including the bacterial species provided in the question, we can list Escherichia coli (E. coli), Staphylococcus aureus (S. aureus), and Micrococcus luteus based on their typical fastidiousness.

Escherichia coli, a Gram-negative coliform species, is known for its ability to grow in a variety of environments with minimal nutritional requirements, which classifies it as the least fastidious of the three. In contrast, Staphylococcus aureus, a Gram-positive species, is moderately fastidious, requiring more specific nutrients and conditions than E. coli, but still capable of growing in many environments. Lastly, Micrococcus luteus is considered highly fastidious, requiring specific nutrients and conditions not necessary for the growth of the other two species, making it the most fastidious in this list.

Therefore, the bacterial species in order of increasing fastidiousness are:

Which conditions need to be in balance for cells to function? Check all that apply.

blood sugar
food intake
body water
body temperature
body mass

Answers

For body cells to function properly, the following conditions need to be balanced:
1. BLOOD SUGAR
2. BODY WATER
3. BODY TEMPERATURE.
These three factors have to be in the right proportion for the cells and the body as a whole to function properly and to maintain homeostasis.
Blood sugar is the source of energy in the cell and it is required by all cell for carrying out the normal biochemical reactions in the body. The biochemical reactions in the body use water as a medium of reaction, thus the water balance in the body must be maintained. The body temperature also need to be kept at the normal level or else the normal biochemical reaction of the body will not be able to take place, due to the fact that incorrect temperatures deactivate the enzymes that mediate biochemical reactions.

The smallest fundamental of any living organism is called a cell. Blood sugar, body temperature and water are the conditions needed by the cell.

What are the factors needed by the cell?

The proper balance and maintenance of the factors are necessary for the cell as they regulate and maintain the cell function and activities. The homeostasis and the function of the cells are maintained by some factors.

Blood sugar is the energy source for the cell to function and carries out the process of the metabolism of the body. The biochemical reaction of the body needs the balance of the water and the temperature.

The normal level of the water and temperature needs to be maintained in the body so that the biochemical reactions can occur properly and the cells do not damage.

The excess or less amount of water will lead to osmosis imbalance and the change in the temperature will affect the enzymes needed for the reactions.

Therefore, options A. Blood sugar, C. body water and D. temperature are correct.

In the gene pool of a population with 350 individuals, a fixed allele has a frequency of

Answers

In the gene pool of population with 350 individuals a fixed allele has a frequency of 1(one). Fixed alleles is the alleles that is the only variant that exist for that gene in all population.The frequency of gene pool with a population of 350 is = 1 since the frequency of total alleles =1

Final answer:

A fixed allele in a population is one where every individual carries the same version of a gene. This means its frequency is 100% in the gene pool, representing complete prevalence in the population's genetic diversity. The study of allele frequency and gene pools is vital in understanding evolution and genetic variation.

Explanation:

The concept of a fixed allele refers to a situation in a genetic makeup where every individual in a population carries the same version (allele) of a gene. In population genetics, the allele frequency, or gene frequency, is the rate at which a specific allele appears within a population. Overall, it's a crucial concept in studying how populations evolve over time. For instance, if an allele provides a survival advantage, it can become more common throughout generations, eventually reaching a point where it's the only version present in the population (a fixed allele).

A gene pool, on the other hand, is the total number of genes of every individual in an interbreeding population. It represents the genetic diversity within a population. So, in a population of 350 individuals, if an allele is fixed, it means that the frequency of that allele is 1 or 100%, as every individual in that population carries that particular allele in their genetic makeup.

An understanding of allele frequency and gene pools is essential to study and understand the process of evolution and genetic variation within a population. Factors like mutation, gene flow, genetic drift, and natural selection all influence the frequency of an allele in a population.

Answers

I believe it is D. More African elephants today naturally lack tusks compared to the elephant populations 100 years ago, because big game hunters sought elephants for ivory.

The correct answer is D. More African elephants today naturally lack tusks compared to the elephant populations 100 years ago, because big game hunters sought elephants for ivory.

Explanation:

In biology, selection occurs as certain organisms with adaptative characteristics prevail over time as they are more likely to reproduce and survive, while organisms with other characteristics disappear. This process can occur by artificial means as human beings intervene in selection.

According to this, the one that is an example of artificial selection is "More African elephants today naturally lack tusks compared to the elephant populations 100 years ago, because big game hunters sought elephants for ivory", because in this case, elephants without tusks are more likely to survive and reproduce and due to this, they are more common today which explains selection. However, this process occurred mainly because of poachers which means there is intervention from human beings and therefore the selection is artificial.

What is the evolutionary value of mutations?

Answers

Diversity and emergence of new traits (can be beneficial in some cases). Mutations are part of what drive evolution and allow for that change to take place.

Mutations are crucial for evolution as they are the primary source of genetic variation. Although most mutations are neutral or harmful, some can be beneficial, leading to better adaptation and evolution. This genetic diversity allows for natural selection and the survival of the fittest.

Mutations are changes to an organism's DNA and are an important driver of diversity in populations. They serve as the ultimate source of genetic variation, which is crucial for evolution. Without them, evolution would not occur.

Most mutations are neutral or harmful, but a small percentage can have beneficial effects, leading to new versions of proteins that enable better adaptation to environmental changes. This genetic diversity allows some individuals to have a survival advantage, leading to natural selection and subsequently, evolution.

For instance, a gene might encode a product with an essential function as well as a potentially useful function for reproductive success. Mutations that enhance these additional functions will persist in the gene pool if they do not overly hinder the gene's primary function. This balance is essential for the flexibility of evolutionary mechanisms.

The results of such indirect measures often allow for a considerably precise prediction of how types of behavior or judgment are influenced.

Read the paragraphs and answer the question that follows.

Over the past 500 years, four large earthquakes have occurred near the same location along a continental-continental transform fault in North America. After scientists observed a nearby stream that crossed the fault, they concluded that the earthquakes had offset the stream by 60 yards from its original course. Thus, on average, each earthquake caused the crust along the fault to slip about 12 yards. The earthquakes caused a lot of damage, as well as dramatic changes to the local ecosystem.

Another area in the fault also experienced a shift in location of 60 yards over 2,000 years. But it did so without suffering a violent earthquake. In this area, the crust along the fault slipped about an inch every year. The slip caused several rock formations and structures to develop cracks. However there was no large-scale disaster or disruption.
