An aneurysm that divides the three layers of the artery wall, as opposed to inflating out the entire wall, is known as a dissecting aneurysm.

Multiple circumstances that lead to the breakdown of the well-organized structural elements (proteins) of the aortic wall, which maintain and stabilize the wall, can result in an aneurysm. Uncertainty surrounds the precise cause. Aneurysmal disease is thought to be significantly influenced by atherosclerosis, which is the hardening of the arteries with plaque.

Surgical intervention can be required since an aneurysm may continue to grow in size and the arterial wall may deteriorate over time. One of the objectives of therapy is to prevent aneurysm rupture. The risk of an aneurysm rupturing increases with its size (bursting). A rupture could lead to fatal hemorrhage (uncontrolled bleeding), which is life-threatening.

Explanation:

The Pigiang Fault is a strike-slip fault.

The forces involved are horizontal shearing forces.

The lateral motion is horizontal and in opposite directions.

The Pigiang Fault is a strike-slip fault and these are typically associated with horizontal shearing forces that cause blocks of rock to move past each other in opposite directions. In the case of the Pigiang Fault, these shearing forces may be caused by tectonic activity along the boundary between two tectonic plates, or by other types of deformation within the Earth's crust.

The relative lateral motion along the Pigiang Fault would be described as horizontal and in opposite directions. As one block of rock moves to the left, the other block moves to the right, with the boundary between the two blocks following the fault plane.

The colony of bacteria is called cit positive, or cit in case these advance with colonization in media with citrate, since if they grow in number and proliferate, it means that they use citrate as a metabolite or food resource for their metabolism.

Explanation:

In case these are negative cit, the profileration would have to be null or see that the colony stagnant its growth, that is to say that they did not increase in number or even decrease their number layers and they did not replicate in media with citrate.

The colony of bacteria is named cit positive, or cit just in case these advance with colonization in media with citrate.

Since if they grow in number and proliferate, it means they use citrate as a metabolite or food resource for metabolism.

In case these are negative cit, the proliferation would have to be null or see that the colony stagnant its growth, that is to say, that they did not increase in number or maybe decrease their number layers and that they didn't replicate in media with citrate.

E. coli, a species of bacteria that lives harmlessly in every person’s gut by the billions. A typical E. coli contains about 4,000 genes (we have about 20,000). Feeding on sugar, the microbe grows till it's able to split in two.

It makes two copies of its genome, nearly always managing to supply perfect copies of the first. The single microbe splits in two, and every new E. coli receives one of the identical genomes. These two bacteria are, in other words, clones.

Explanation:

The evolution of the rock pocket mouse is a great example of how natural selection can lead to the adaptation of a species to its environment. The mutations that occurred on the Mc1r gene allowed some individuals of the population to have a different fur coloration than the rest of the population. This new fur coloration provided a selective advantage to the mice living in the darker volcanic rock environment.

The darker fur of the rock pocket mouse provided camouflage against predators, allowing them to blend in with the dark rocks and avoid being seen. This made them less likely to be preyed upon by predators such as owls and snakes, which hunt by sight. As a result, the mice with the darker fur were more likely to survive and pass on their genes to the next generation.

Over time, as the population of the rock pocket mouse continued to be exposed to predation, the proportion of individuals with the darker fur coloration increased. This is because the individuals with the darker fur coloration were more likely to survive and reproduce, passing on their advantageous traits to their offspring. Eventually, the population became dominated by individuals with the darker fur coloration, and the rock pocket mouse became a distinct species.

This process, in which mutations that provide a selective advantage become more common in a population over time, is known as natural selection. In the case of the rock pocket mouse, the mutations that occurred on the Mc1r gene allowed the mice to adapt to their environment and avoid predation, ultimately leading to the evolution of a new species.

Explanation:

A substance requires energy to move across a membrane when it moves from (C) Low concentration to High concentration

The process of moving a substance across the cell membrane from high to low concentration is known as passive transport, which does not require energy. Active transport, on the other hand, is the process of moving a substance from low to high concentration, which requires energy.

The movement of molecules against their concentration gradient (low to high concentration) requires an energy source, which is usually in the form of ATP (adenosine triphosphate). Low concentration to High concentration. During active transport, the substance moves against its concentration gradient, which means it moves from an area of lower concentration to an area of higher concentration.

This process requires energy, which is provided by ATP. Active transport is responsible for the uptake of nutrients, such as glucose and amino acids, in cells. The process of active transport is crucial in maintaining the proper concentration of ions in cells. Additionally, active transport is essential for maintaining the pH of cells and the function of enzymes. Overall, active transport is an energy-intensive process that is vital for cellular homeostasis and function. The correct answer is C.

Explanation:

Photosynthesis takes C02 out of the air, meaning that less trees = less photosynthesis = more C02

Answer:

5730 years

Explanation:

In a chemical reaction, including radioactive decay, the half-life of a species is the time taken for the substance to decrease to exactly one-half its initial value.

For a first-order reaction, the half-life of the reactant is

                                                  \(t_{\frac{1}{2}} \ = \ \displaystyle\frac{\ln 2}{\lambda} \ \ \ \ \ \ (1)\),

where λ is the reaction's rate constant modeled by the differential equation describing the kinetics of a first-order reaction

                                               \(N \ = \ N_{0}e^{-\lambda t} \ \ \ \ \ (2)\),

where N is the remaining amount of substance after time t and \(N_{0}\) is the initial amount of substance before the chemical reaction proceeds.

Since the value of λ is constant, rearrange equation (1) with λ as the subject,

                                                       \(\lambda \ = \ \displaystyle\frac{\ln 2}{t_{\frac{1}{2}}}\).

Given that only 12.5% of carbon-14 remained after 17190 years assuming that initially there was 100% of carbon -14, substitute in the values into equation (2) and solve for λ (make λ the subject of the equation),

                               \(\-\hspace{0.56cm}12.5 \ = \ 100e^{-\lambda \times 17190} \\ \\ \-\hspace{0.5cm} \displaystyle\frac{12.5}{100} \ = \ e^{-17190\lambda} \\ \\ \displaystyle\frac{\ln\displaystyle(\frac{1}{8})}{-17190} \ = \ \lambda \\ \\ \-\hspace{1.05cm} \lambda \ = \ \displaystyle\frac{3\ln2}{17910} \ \ \ \ \ \ \ \ \ \ (\ln \displaystyle\frac{1}{x} \ = \ -\ln x\ ; \ \ln x^{n} \ = \ n\ln x )\)

Equate both λ,

                                            \(\displaystyle\frac{\ln 2}{t_{\frac{1}{2}}} \ = \ \displaystyle\frac{3\ln2}{17190} \\ \\ \-\hspace{0.26cm} t_{\frac{1}{2}} \ = \ \ln 2 \ \times \ \displaystyle\frac{17190}{3\ln2} \\ \\ \-\hspace{0.26cm} t_{\frac{1}{2}} \ = \ \displaystyle\frac{17190}{3} \\ \\ \-\hspace{0.26cm} t_{\frac{1}{2}} \ = \ 5730\)

*Note that the above calculations demonstrated that carbon-14 went through 3 half-lives to yield a remaining 12.5% of its original amount, since

                                 \(100\% \ \overset{t_{\frac{1}{2}}}\longrightarrow \ 50\% \ \overset{t_{\frac{1}{2}}}\longrightarrow \ 25\% \overset{t_{\frac{1}{2}}}\longrightarrow \ 12.5\%\).

Therefore, if n is the time taken for carbon-14 to half its initial amount trice to remain 12.5% of its initial amount. Then, the half-life of carbon-14 is \(\displaystyle\frac{n}{3}\).

Explanation:

I hope this helps.

From this pedigree we can assume a trait coded by a recessive allele from an autosomal gene that expresses complete dominance. Parents 3, 4, 5, and 6 are heterozygous, which is why they are not affected. Individuals 9, 11, and 12 received only recessive alleles from their parents, and this is why they are affected (genotype aa).

A Pedigree is the representation of a family's history. This graph is used to track a trait through different generations, and analyze the inheritance pattern of a particular gene and its expression.

It is a tool used to understand how genes are transmitted from the parental generation to the descendants, and what are the probabilities of  inheriting them.

Pedigree interpretation.

→ Individuals are represented with geometrical figures.

→ Males are squares

→ Females are circles

→ Healthy/normal/not affected  individuals are represented with empty figures

→ Affected/mutated individuals are represented with solid black figures

→ Each file is represented with a roman number, indicating the Generation.

In the exposed example, affected individuals have a genotype aa (recessive trait), while unaffected individuals have at least one dominant allele in their genotypes (AA or Aa).

Individuals 9, 11, and 12 have the disorder because they received a recessive allele from each of their heterozygous parents (the mother transmitted a recessive allele and the father transmitted another recessive allele).

All parents (II3, II4, II5, and II6) are heterozygous, Aa. Each of them have 50% chances of passing a recessive allele to their progeny and 50% chances of passing a dominant allele.

The progeny of each couple has 75% chances of being unaffected (25% AA + 50% Aa) and 25% chances of being affected (25%aa).

This is,

Cross:

Parentals) Aa   x   Aa

Gametes) A   a    A    a

Punnett square)     A      a

                       A     AA     Aa

F1) The expected genotypes among the progeny are

   The expected phenotypes among the progeny are

The first couple (II3 x II4) has an unaffected child AA and an affected one aa.

Considering the probabilities of these outcomes, the chance of having a child with blood type O is 50% if a man with blood type AB marries a woman who is heterozygous for blood type B.

To determine the probability of having a child with blood type O, we need to analyze the possible blood type combinations that can result from the parents' genotypes.

The man has blood type AB, which means he has both A and B antigens on his red blood cells. The woman is heterozygous for blood type B, meaning she carries one B allele and one recessive O allele. The possible genotypes for the man are AB (IAIB) and the possible genotypes for the woman are BB (IBIB) or BO (IBi).

When these two individuals have offspring, their children can inherit any combination of the parents' alleles. The possible combinations are as follows:

AB x BB: All children will have blood type B (IBIB), as both parents only carry the B allele.AB x BO: There is a 50% chance that each child will inherit the O allele from the mother, resulting in blood type O (ii). There is also a 50% chance that each child will inherit the B allele from the mother, resulting in blood type B (IBi).
