Where does P. acne colonize within the human microbiome?
Answers
P. acne, or Propionibacterium acnes, is a type of bacteria that commonly colonizes the human skin. Specifically, P. acne tends to reside within the sebaceous glands and hair follicles on the face, neck, chest, and back.
This bacterium is known to play a role in the development of acne, as it feeds on sebum (oil) produced by the skin and can cause inflammation and infection in the hair follicle. While P. acne is a normal resident of the skin microbiome, overgrowth and imbalance can lead to skin issues. In particular, P. acnes is known to colonize within hair follicles and sebaceous glands in the skin. It can also be found in lower numbers in other areas of the skin, such as the armpits and groin.
While P. acnes is a normal part of the human skin microbiome and is generally harmless, it can sometimes contribute to the development of acne. When there is an excess of sebum production or other factors that promote bacterial growth, P. acnes can multiply and cause inflammation, leading to the formation of pimples, blackheads, and other types of acne lesions.

The three elephant activities or functions that justify why elephants are a keystone species is that
They trample forests and dense grasslands, making room for smaller species to co-exist. Elephants also create water holes used by other wildlife as they dig dry riverbeds when rainfall is low. Herds travel over vast rangelands, and they disperse seeds in their dung, which helps generate new green growth.Each of the three activity or function changes African ecosystems in the sense that they play an important role in maintaining the biodiversity of the ecosystems in Africa as they are seen as icons of the continent playing a role as tourism magnets, attracting funding that helps protect wilderness areas.
What are keystone species?A keystone specie is described as a species which has a disproportionately large effect on its natural environment relative to its abundance, a concept introduced in 1969 by the zoologist Robert T. Paine.
They are called keystone specie because they fill a critical ecological role that no other species can. Without its keystone species, an entire ecosystem would radically change—or cease to exist altogether.

Tropical rainforests have the greatest biodiversity of any type of land ecosystem how does biodiversity contribute to the sustainability of an ecosystem
Answers
Biodiversity contributes to the sustainability of an ecosystem in ways such as biodiversity, ecosystem stability, ecosystem resilience, nutrient cycling, pollination, and medicinal properties.
Biodiversity is crucial for the sustainability of an ecosystem as it plays a significant role in maintaining the functioning of ecosystems and providing a range of ecological services. In tropical rainforests, which have the highest biodiversity, the presence of numerous species of plants, animals, fungi, and microorganisms contributes to the sustainability of the ecosystem in the following ways:
Ecosystem Stability: Biodiversity helps to maintain the stability of an ecosystem by providing a balance between predator and prey populations, nutrient cycling, and decomposition.
Ecosystem Resilience: The greater the biodiversity of an ecosystem, the more resilient it is to disturbances such as climate change, natural disasters, and human activities.
Nutrient Cycling: Biodiversity helps in the efficient cycling of nutrients in the ecosystem. Different species of plants and microorganisms play a role in decomposing organic matter, recycling nutrients, and maintaining soil fertility.
In summary, biodiversity is essential for the sustainability of ecosystems. It provides ecological services that are critical for maintaining the functioning of the ecosystem and contributing to human well-being.

the forensic analyst is asked to testify in court regarding her findings. she is asked by the prosecutor how certain she can be that the dna on the handgun came from the suspect. using the allele frequency information provided, how often would she expect to find a match to the crime scene dna profile in the general population?
Answers
The correct answer is option D) Using the allele frequency information provided, she would expect to find a match to the crime scene DNA profile in the general population with a probability of: 1 in 10,000.
The likelihood that a randomly selected person from the general population would match the DNA profile discovered on the firearm can be calculated using the allele frequency data provided by the prosecutor.
The combined frequency of the profile is calculated by summing the separate allele frequencies.
For instance, the combined frequency of the profile would be 0.02 (0.1 x 0.2) if the allele frequencies for a single locus were 0.1 and 0.2. According to this frequency, the likelihood of discovering a match to the crime scene profile in the general population is 1 in 10,000 (1/0.02).
This indicates that the forensic analyst may be confident that the suspect provided the DNA on the weapon with a probability of 1 in 10,000.

How Do You "Win" At Natural Selection?
Answers
Answer:
choose the best option?
Explanation:
"Winning" at natural selection refers to successfully passing on one's genes to the next generation.
What is natural selection?Natural selection is a mechanism of evolution that favors traits that increase an organism's chances of surviving and reproducing. In order to "win" at natural selection, an organism must have traits that help it survive and reproduce in its particular environment.
For example, a bird with a beak that is well-suited to its particular food source is more likely to survive and pass on its genes than a bird with a less suitable beak. However, it's important to note that natural selection is not a conscious or deliberate process, and there is no "goal" or "endgame" to evolution. Instead, it is simply a description of the mechanism by which species change over time.

Natural disasters in an ecosystem are density-independent limiting factors because their effects do not depend on the size of the population. The natural greenhouse effect involves trapping heat from the sun to keep the planet warm enough to support life.
Thus, the greater the biodiversity in an ecosystem, the more stable will be the ecosystem. Habitat destruction is the greatest threat to biodiversity. The agricultural green revolution and the availability of antibiotics are responsible for increase in human population. Burning fossil fuels releases carbon dioxide into the atmosphere which are contributing to global warming.

The main function of the cardiovascular system is to: deliver oxygen to cells. Option(b)
The cardiovascular system consists of the heart, blood vessels, and blood. Its primary role is to transport oxygen, nutrients, hormones, and other essential substances to the cells of the body.
Oxygenated blood is pumped by the heart through arteries to reach the tissues, where oxygen is released and utilized by the cells for various metabolic processes. Simultaneously, the cardiovascular system also collects waste products, such as carbon dioxide, from the cells and transports them to the lungs for elimination.

¿Cuántos gramos de dióxido de carbono (CO2) se producen si se quema 40 gramos del hidrocarburo ( C3H8 )?
Answers
Answer:
120 gramos de CO₂
Explanation:
La ecuación química balanceada para la reacción de combustión del hidrocarburo C₃H₈ (propano) es la siguiente:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
Por lo tanto, 1 mol de C₃H₈ produce 3 moles de CO₂. Ahora debemos convertir las moles a gramos utilizando el peso molecular (PM) de cada compuesto:
PM(C₃H₈)= (3 x 12 g/mol) + (8 x 1 g/mol) = 44 g/mol
1 mol C₃H₈ = 1 mol x 44 g/mol = 44 g
PM(CO₂) = 12 g/mol + (16 g/mol x 2) = 44 g/mol
3 mol CO₂ = 3 mol x 44 g/mol = 132 g
Por lo tanto, se producen 132 gramos de CO₂ a partir de 44 gramos de C₃H₈ y la relación estequiométrica es:
3 mol CO₂/1 mol C₃H₈ = 132 g CO₂/44 g C₃H₈
Finalmente, para calcular cuántos gramos de CO₂ se producen al quemar 40 g de C₃H₈, multiplicamos la relación estequiométrica por la masa a quemar:
masa CO₂ producida = 40 g C₃H₈ x 132 g CO₂/44 g C₃H₈= 120 g
