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.

Annotate the symbol by the reference image. Then, explain why this symbol represents an ion and how many electrons it has.
• the name of the element
• the charge
• the mass number
• the atomic number
Answer:
since the symbol has a "+1" sign at the top right corner it represents a positively charged ion.
it has 4 electrons as it has "+1" symbol meaning it lost one electron out of initially 5 electrons present.
name of element = Boronthe charge = +1the mass number = 11the atomic number = 5Answer: ion has a 2+ charge then it must have lost electrons to form the cation. If the ion has 18 electrons and the atom lost 2 to form the ion, then the neutral atom contained 20 electrons. Since it was neutral, it must also have had 20 protons. Therefore the element is calcium.

A. Coats guard hairs to improve their informance
B. Usually opens up into a hair follicle
C. Simple, coiled, tubular glands
D. Secretes earwax
E. Coats the scalp hair with oil
F. Blockage and infection can cause pimples
1. Sebaceous
2. Ceruminous
Answer:
A. Ceruminous
B. Sebaceous
C. Ceruminous
D. Ceruminous
E. Sebaceous
F. Sebaceous
Explanation:
Ceruminous glands are modified sweat glands located subcutaneously in the cartilaginous two-thirds of the external auditory canal. Ceruminous glands produce together with sebaceous glands the cerumen (i.e. earwax), which protects the ear canal against physical damage and/or microbial infections. On the other hand, sebaceous glands are glands in the skin that secrete sebum, an oily, waxy substance that lubricates the hair and skin of mammals. These glands (sebaceous) are affected by sex hormones like testosterone that enlarges the glands due to the increased cell proliferation rate and estradiol, which reduces the size of the glands due to the accelerated cell breakdown. Sebaceous glands are holocrine glands in which secretions are produced in the cytoplasm of the cells and then they are released by the rupture of the plasma membrane, while ceruminous glands are apocrine glands where the accumulated secretion is pinched off with a portion of the cell.
Which of the following is an example of non Mendelian pattern of inheritance
Answer:
Genomic imprinting represents yet another example of non-Mendelian inheritance. Just as in conventional inheritance, genes for a given trait are passed down to progeny from both parents. However, these genes are epigenetically marked before transmission, altering their levels of expression.Answer:

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.

A reversible inhibitor that only affects multi substrate enzymes and binds to the enzyme only after one substrate has bound is a(n) ___
Answer:
Uncompetitive inhibitor.
Explanation:
Enzymes are the biological catalysts that catalyze the biological process and metabolic activity of the body. Without enzymes, all the biological activity becomes very slow. Enzyme provides suitable speed for the biological process. All enzymes are made up of protein. The uncompetitive inhibitor is the type of enzyme that only disturbs or affects multi-substrate enzymes and joins to enzymes only after one substrate has bound.
