Which series of terms is in the sequence of biological organization from the simplest to the most complex. a) community, population, ecosystem, habitat, biosphere b) tissue, organ system, organ, cell, organism c) organism, ecosystem, community, population, biosphere d) cell, tissue, organ, population, community e) molecule, tissue, cell, organelle, organ 2. in which kingdom can multicellular, eukaryotic, photosynthetic organisms be found? a) archaea b) fungi c) protista d) plantae e) animalia

1. d) cell, tissue, organ, population, community.

2. d) Plantae

Explanation:

1. Cells can be grouped to form tissues, a tissue is a specialized part of an organ. Different organs make systems inside an organism. Organisms that can mate each others  are a species. A defined number of organisms of the same species that live in a determined place is a population. And a community is a group of different species that interact together.

2. The only option in which multicellular, eukaryotic and photosynthetic organisms can be found is Plantae.

In Archea all organisms are unicellular.

In Fungi, we can find multicellular and eukaryotic organisms, but they are not photosynthetic.

Protista is a group of unicellular and eukaryotic organisms, but they are not multicellular.

1. d) cell, tissue, organ, population, community

2. d) Plantae

Explanation:

1. Biological organization is commonly thought by biologist as a continuous sequence of hierarchically organized categories or levels. When moving from one level to a higher (more inclusive) one, at least one emergent property appears, this is, a property that cannot be accounted by any combination of the elements and properties from lower levels.

The fundamental unit of life is the cell as it represents the first level where the emergent property "life" appears. When a group of similar cells are organized in a particular biological arrangement and present similar biological properties, they conform a tissue. When different tissues are layed and organized into a specialized structure with specific biological functions, this is known as organ. Different organs compone a system (of organs). Several systems give functionality to a multicellular organism.

Organisms of the same species which can reproduce, give fertile offspring, and live in the same place and time are part of a population.

Populations of different species living in the same place and time conform a community.

2. Archae is a kingdom represented by antiques bacteria, which ofen live in extreme conditions (absence of oxygen or light, high concentration of salt or toxic substances, etc.) Thus, they are all prokaryotic.

Fungi is represented by heterothopic, absorptive eukaryotic organisms. Like Animals (which belong to the kingdom Animalia) they do not have any photosynthetic pigment (like chlorophyll).

Protista is the kingdom that groups several eukaryotic organisms but all of them being unicellular.

On the other hand, Plantae consist of all the groups of vascular plants (tracheophytes: ferns, conifers and flowering plants) but also briophytes (mosses, hornworts and liverworts). All of these representatives are autothropic multi-cellular organisms that produce sugars through phtotosyntesis.  

the cytokine-activated janus kinase (jak)-signal transducer and activator of transcription (stat) pathway has an important role in the control of immune responses. dysregulation of jak-stat signaling is associated with various immune disorders.
