The rate at which the concentration of a drug in the bloodstream decreases is proportional to the concentration at any time t. Initially, the concentration of the drug in the bloodstream is C0 g/mL. What is the concentration of the drug in the bloodstream any time t
Answer:
[tex]C(t) = C_oe^{-kt}[/tex]
Explanation:
From the given information:
At any given time (t), let c(t) represent the concentration of the drug present in bloodstream.
Deriving the equation:
[tex]\dfrac{dC}{dt}[/tex] decrease proportionally to Concentration C
i.e
[tex]\dfrac{dc}{dt} \alpha - C[/tex]
[tex]\dfrac{dc}{dt} = -k C[/tex]
[tex]\dfrac{dc}{c} = -k dt[/tex]
[tex]\int \dfrac{dc}{c} = -k \int dt[/tex]
㏑(C) = -kt + λ
where,
λ is the integration constant.
Integrating at t = 0, concentration of blood = Co g/mL
C(0) = Co
㏑(C₀) = 0 + λ
λ = ㏑(C₀)
From ㏑(C) = -kt + λ
㏑(C) = -kt + ㏑C₀
㏑(C) - ㏑C₀ = -kt
[tex]\dfrac{C}{C_o} = e^{-kt}[/tex]
[tex]C(t) = C_oe^{-kt}[/tex]
∴
The concentration of drug in blood at any time t is:
[tex]C(t) = C_oe^{-kt}[/tex]

Hydrothermal vent ecosystems do not have sunlight available, and hence there are no kinetic energy. Instead, play the role of on which other organisms rely for energy. They compounds such as hydrogen sulfide to obtain energy for themselves. This energy is used to sugar molecules. create an additional energy transfer when they these sugars or eat each other. As in other ecosystems, organisms in hydrothermal vent communities also transform into other forms, such as (energy of motion).
Answer:
- Hydrothermal vent ecosystems do not have sunlight available and hence there are no photoautotrophs.
- Instead, chemoautotrophs play the role of producers on which other organisms rely for energy. They oxidize compounds such as hydrogen sulfide to obtain energy for themselves. This energy is used to synthesize sugar molecules.
- Consumers create an additional energy transfer when they utilize these sugars or eat each other.
- As in other ecosystem organisms in hydrothermal vent communities also transforms chemical energy into other forms such as kinetic energy (energy of motion).
Explanation:
A hydrothermal vent is a geyser on the seafloor that is generated by underwater volcanoes or tectonic activity through which geothermally heated water erupts. Hydrothermal vent ecosystems contain hydrothermal microorganisms which are able to survive just outside the hottest waters. For example, Methanopyrus kandleri are hyperthermophile prokaryotic microorganisms that live in these ecosystems where they produce methane from reducing CO2. Chemosynthesizers are able to convert carbon molecules (e.g., CO2) and nutrients into organic matter by the oxidation of inorganic compounds such as hydrogen sulfide and/or ferrous ions. Moreover, hydrothermal vent ecosystems have the potential to support high biomass and productivity levels due to the establishment of symbiotic relationships between chemosynthesizers with respiring heterotrophs, which obtain energy from other organisms. Chemosynthesizers are eaten by other organisms (e.g., amphipods and copepods), whereas larger organisms (e.g., snails and crabs) form predator and prey relationships above these primary consumers.
This is the type of ecosystem found on seafloor with geothermally heated water discharges. It lacks sunlight and there are no presence of photoautotrophs.
Organisms present mostly convert chemical energy into other available forms.

You have a novel virus that can kill mice when injected into them. This novel virus can transform a non-virulent virus, causing it to become virulent. You want to understand what the transforming factor is made of. You heat kill the novel virus and treat different samples of the heat killed sample with either an RNase, a DNase, or a Proteinase. Of the novel virus uses double-stranded RNA as its genetic material, which treated sample will no longer be capable of transforming the non-virulent strain
Answer:
The sample treated with RNase
Explanation:
According to this question, a novel virus was found which was capable of killing mice when injected into them and capable of making a nonvirulent virus to be virulent by transforming them.
After heat killing the novel virus, different samples were treated with either an RNase, a DNase, or a Proteinase. If the novel virus uses double-stranded RNA as its genetic material, the sample treated with RNase will no longer be capable of transforming the non-virulent strain. This is because RNase is a catalytic enzyme that degrades RNA, hence, the RNA will no longer be present to transform.

Question 5 of 30 Which statement provides the best description of the relationship between primary consumers and producers? O A. Producers and primary consumers compete with each other for food sources. B. Primary consumers eat secondary consumers, which rely on producers for food. C. Producers provide primary consumers with the chemical energy they need. D. Primary consumers provide producers with the chemical energy they need.
10% of the energy stored in the producer's tissues is used by herbivores. Option C. Producers provide primary consumers with the chemical energy they need.
What is a trophic web?
The trophic web is the interaction between different organisms involving the transference of energy when some of them feed on the other ones.
The ones placed at lower levels pass energy to the ones at the higher levels. Only 10% of the energy stored in each individual's tissues is transmitted to its predator. The remaining 90% of energy is released into the environment.
Organisms at each level feed on the preceding one and become food for the next one.
• The first link corresponds to a producer organism -autotroph-.
• The following links are the consumers -heterotrophs-: herbivores and carnivores.
• The last links are the decomposers that degrade organic matter from dead organisms.
Because it is a web, all organisms are in equilibrium until a change occurs. When a sudden change affects any of the involved links, there can be a cascade effect on the web.
Any change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.
Options:
A. Producers and primary consumers compete with each other for food sources ⇒ False. they do not compete. Producers take energy from the sun, while primary consumers take energy from producers.
B. Primary consumers eat secondary consumers, which rely on producers for food. ⇒ False. Secondary consumers feed on primary consumers.
C. Producers provide primary consumers with the chemical energy they need. ⇒ False. True. 10% of the energy stored in the producer's tissues is provided to primary consumers -herbivores-.
D. Primary consumers provide producers with the chemical energy they need.⇒ False. Primary consumers use the energy from the producers.
The correct option is C. Producers provide primary consumers with the chemical energy they need.

fungsionalisme adalah?
Answer:
Teori adalah suatu pendapat bagaimana dan kenapa sebuah fakta terjadi. (Macionis, 1997:15). Sedangkan Scupin dan De Corse (1995)mendefinisikan teori adalah kumpulan hipotesis yang tidak berhubungan yang menawarkan penjelasan secara umum untuk fenomena natural atau sosial. Salah satu teori Antropologi adalah fungsionalisme.
Teori fungsionalisme adalah teori dominan dalam antropologi. Teori ini memandang budaya sebagai satu kesatuan, dan mencoba untuk menjelaskan bagaimana hubungan antara bagian-bagian masyarakat yang tercipta dan bagaimana bagian ini fungsional (bermakan memiliki konsekuensi yang menguntungkan pada individu dan masyarakat) dan disfungsional (bermakna memiliki konsekuensi negatif). Teori ini memandang masyarakat sebagai sistem yang kompleks yang mana bagian tersebut bekerja bersama untuk mempromosikan solidaritas dan stabilitas; ini menandakan bahwa kehidupan sosia kita dituntun berdasar pada struktur sosial, yang pola perilaku sosialnya secara relatif stabil (Macionis, 1997)
Seluruh struktur sosial berkntribusi pada operasi masyarakat. Dua antropolog inggris terkemuka Radcliff Brown dan Bronslaw Malinowski, menggambarkan dua standar teori: Struktural fungsionalisme, yang menekankan pada keunggulan dari masyarakat dan menyusun para individu, dan bagaimana berbagai macam elemenfungsi struktur sosial untuk memelihara permintaan sosial dan keseimbangan. Dan Psikologi strukturalisme, yang mana menekankan pada kbutuhan individual untuk bertemu dengan masyarakat.
Kelemahan teori fungsional adalah gagalnya menjelaskan kenapa masyarakat itu berbeda atau justru memiliki kesamaan. Ontropolog fungsionalisme menganggap dunia tertib, memberi sedikit perhatian atau bahkan tidak memberi perhatian pada kompetisi dan konflik (Howard dan Dunaif-Hattis, 1992). Teori ini tidak berhubungan dengan sejarah, mengabaikan proses sejarah. (Scupin dan De Corse, 1995) teori ini juga tidak dapat menjelaskan perubahan sosial dan budaya, sebagaimana ia dulu memandang masyarakat sebagai sesuatu yang stabil dan tetap. meskipun memiliki kelemahan, teori fungsionalisme mempengaruhi perjanjian besar penelitian empirik dalam antropologi.

The angle subtended by a section of a circle is
100". If the perimeter of the sector is 150cm
calculate the radius
Answer:
Radius of circle = 40 cm (Approx.)
Explanation:
Given:
Angle subtended by a section = 100°
Perimeter of the sector = 150cm
Find:
Radius of circle
Computation:
Perimeter of the sector = 2[Radius of circle] + Length or arc
150 = 2[r] + [θ/360][2πr]
150 = 2[r] + [100/360][2(3.14)r]
150 = 2[r] + [0.277][2(3.14)r]
150 = 2[r] + 1.74r
150 = 3.74r
r = 40 cm (Approx.)
Radius of circle = 40 cm (Approx.)
