Why can some medicines be absorbed through the skin?
Answer:
Explanation:
Some medication can be absorbed through the skin as the skin or mucous membranes allow it to enter through the body. Most drug absorbtion occurs between cells by passing through sweat pores and hair follicles, making it transcellular. Thus, topical medication is able to be absorbed through the skin due to pores and hair follicles.

Air pollution is effecting national Park in which way
Air pollution is one of the most serious threats facing national parks, harming visitors’ health, clouding scenic views and altering our climate. The air pollution affecting national parks — and the rest of the country — results from the burning of fossil fuels by power plants, oil and gas development, vehicles, agriculture, industrial emissions, and other sources. NPCA works to make sure our nation’s air laws are strong, to hold polluters and government accountable to those laws, and ultimately, to reduce the air pollution that harms our parks, climate and communities.
Defending Federal Laws and Regulations
The Clean Air Act – which has helped improve air quality throughout the nation and the National Park System – is now under consistent threat as the Environmental Protection Agency works to roll back regulations, attack the use of science and offer polluters loopholes. NPCA advocates to defend and strengthen the clean air laws that protect park skies. We speak out for science and guard against policies driven only by politics and private industry.
Holding Polluters and Governments Accountable
Picture park skies free of pollution. While this sadly isn’t the case today, NPCA strives to make sure that parks are on the right track and that air pollution harming parks is reduced. We do this by helping to secure strong state plans to limit haze-causing and climate-altering pollution, and by defending existing plans – in court, if necessary.
Advocating for Pollution ReductionClean air laws are meaningless if polluters and the government don’t follow them. NPCA vigilantly monitors for sources that violate their permits or when officials aren’t following through on the safeguards in place to protect parks. We also look for opportunities to collaborate and work in state, local or regional processes to prevent threats of new pollution and help reduce harmful emissions.

Assuming the population begins in H−W equilibrium, what is C1 allele frequency after one generation of natural selection? Express your answer using three decimal places.
Complete question:
In a population of flowers growing in a meadow, C1 and C2 are autosomal codominant alleles that control flower color. The alleles are polymorphic in the population, with f (C1) = 0.7 and f (C2) = 0.3. Flowers that are C1C1 are yellow, orange flowers are C1C2, and C2C2 flowers are red. A storm blows a new species of hungry insects into the meadow, and they begin to eat yellow and orange flowers but not red flowers. The predation exerts strong natural selection on the flower population, resulting in relative fitness values of C1C1 = 0.30, C1C2 = 0.60, and C2C2 = 1.0. Assuming the population begins in H−W equilibrium, what is C1 allele frequency after one generation of natural selection? Express your answer using three decimal places.
Answer:
The C1 allele frequency after one generation of natural selection equals 0.559

Although all genetic diversity originates as a mutation there are two mechanisms that occur during meiosis that can recombine existing genetic diversity into many trillion of new combinations what are these two mechanisms a. organization of DNA around histone molecules b. variability in the arrangement of Acton and meiosis molecules in the meiotic spindle c. Random assortment of alleles during metaphase one of meiosis d. telomeric shortening after successive rounds of cellular division e. Crossing over between homologous sister chromatids
Answer:
option E is the correct crossing over between sister chromatids crossing over is important because it is a source of genetic variation and leads to different mutations (changes) in the body of zygote
Explanation:
i hope this will help you :)
The mechanism above described that can recombine existing genetic diversity during meiosis is the 'random assortment of alleles during metaphase I of meiosis' (Option c).
During the metaphase of meiosis I, the homologous pairs of chromosomes line up at the equator of the cell.
During anaphase I, these chromosomes are pulled toward opposite poles of the cell in order to form haploid cells, thereby the separation (i.e., assortment) of homologous chromosomes is random.
This process (i.e., independent assortment) results in a huge variety of possible genetic arrangements.
The crossing over between homologous non-sister chromatids represents another mechanism that can recombine existing genetic diversity during meiosis, but this option does not appear above.
Crossing over refers to the exchange of genetic material between non-sister chromatids during meiosis I (prophase I).
In conclusion, the mechanism that can recombine existing genetic diversity during meiosis is the 'random assortment of alleles during metaphase I of meiosis' (Option c).

Biochemical signaling that is transduced via the protein tyrosine kinase signal transduction cascade is involved in regulating cell growth and differentiation. Identify one example from the scientific literature of an example of how either structural proteins or enzymes involved in this pathway can used as viable anticancer targets. Please include the reference that you use.
Answer:
Tyrosine kinases are therapeutic targets for anticancer compounds
Explanation:
Tyrosine kinases are a type of enzymes capable of activating signaling network pathways by protein phosphorylation, which is a posttranslational modification where one phosphate group is added to the protein and thereby activating it. In the last years, tyrosine kinases have been used as therapeutic anticancer agents. For example, it has been shown that c-MET proto-oncogene, a receptor tyrosine kinase involved in signaling pathways, is targeted by the PROteolysis TArgeting Chimera (PROTAC). PROTAC is a drug that acts as an enzyme capable of removing unwanted proteins bound to this receptor.

what mechanisms does the body use to turn responses on and off to maintain homeostasis?
A fight-or-flight mechanisms
B Homeostasis mechanisms
C Input mechanisms
D Feedback mechanisms
Answer:
D Feedback mechanisms
Explanation:
Not 100% sure but strongly believe option D should be correct, if not then B. Homeostasis mechanisms would be my second bet.
I say D because our body has feedback loops which keep everything in check and they are responsible for turning on or off certain things in our body. You probably have heard of Negative and Positive feedback loops those are what I am referring to as they are the main mechanisms which control the homeostatis thus D is my best bet.
Feedback mechanisms are used by the body to switch on and off responses to maintain homeostasis. Therefore, the correct option is D.
To maintain homeostasis, the body uses feedback systems to activate and deactivate responses. To maintain internal consistency, feedback systems require observation and control of physiological processes. These mechanisms often involve negative feedback loops, in which the body recognizes deviations from the ideal state and initiates responses to counteract those deviations and restore the balance of the system.
For example, if body temperature rises above a set point, negative feedback processes such as sweating and vasodilation are triggered to cool the body. Conversely, if body temperature falls below the set point, negative feedback mechanisms such as shivering and vasoconstriction are activated to promote heat production and retain heat.
Therefore, the correct option is D.
