Why is water considered to be abiotic?

Answers

Answer 1
Water is considered an abiotic factor in the ecosystem because it is a non-living part of the ecosystem. Water is very important to al living things and no living organism can survive without it. Other abiotic factors in the ecosystem are soil, rocks, sunlight, oxygen, etc.
Answer 2

Answer: Water is a nonliving factor so it is considered abiotic. Abiotic is any nonliving factor of the ecosystem, With said that water is not living so it is considered abiotic. Hope this helps.

What is energy cycle in an ecosystem?

The energy flow in the ecosystem is important to maintain an ecological balance in the ecosystem. The producers in a food chain synthesize food by the process of photosynthesis. A part of this energy is stored within the plant species.

The energy cycle in an ecosystem is based on the flow of energy through the ecosystem. The energy from sunlight is converted by the plants them into the growing new plant materials including the flowers, fruits, branches, trunks, and roots of the plants. Since, the plants can grow by converting solar energy directly into their tissues.

How is the epithelium suited for the substances ?

Answers

Answer:

Epithelial tissue is composed of cells laid together in sheets with the cells tightly connected to one another. Epithelial layers are avascular, but innervated.

Epithelial cells have two surfaces that differ in both structure and function.

The epithelial cells are nourished by substances diffusing from blood vessels in the underlying connective tissue. One side of the epithelial cell is oriented towards the surface of the tissue, body cavity, or external environment and the other surface is joined to a basement membrane. The basement layer is non-cellular in nature and helps to cement the epithelial tissue to the underlying structures.

30. ___________ occurs when sediments are squeezed together by the weight of overlying sediments on top of them.

Answers

Answer:

21. Intrusive igneous rocks solidify beneath the surface.

22. Slow cooling allows time for large crystals to form.

23. Sediments are laid down, or Compacted, before they can be formed into sedimentary rocks.

24. Fluids that crystallize in the spaces between the loose particles of sediments create rock by Cementation.

25. Regional metamorphism changes enormous quantities of rock over a wide area.

26. Contact metamorphism changes a rock that is in contact with magma because of the extreme heat.

27. In a metamorphic, minerals separate by Bedding into lighter and darker bands.

28. The rocks that form from an erupting volcano are Extrusive Igneous rocks.

29. Cemented sediments become Clastic sedimentary rocks.

30. Lithification occurs when sediments are squeezed together by the weight of overlying sediments on top of them.

The correct blanks are Intrusive, Slow, deposited, cementation, Regional, Contact, Foliation, volcanic, igneous, lithified, and Compaction.

Igneous rocks are a type of rock that forms from the solidification and crystallization of molten material, known as magma or lava.

Intrusive igneous rocks, also known as plutonic rocks, form when molten magma cools and solidifies beneath the Earth's surface.When molten magma or lava cools slowly, it provides sufficient time for the atoms and molecules within the molten material to arrange themselves in an orderly manner. The process of deposition refers to the settling or accumulation of sediments, which are fragments of rocks, minerals, organic matter, or other particles, onto a surface.Cementation is a process in which minerals in fluid form, often dissolved in groundwater, precipitate and crystallize within the pore spaces of sedimentary materials. During regional metamorphism, large volumes of rock are subjected to significant heat and pressure, typically deep within the Earth's crust. Contact metamorphism, also known as thermal metamorphism, occurs when a rock comes into direct contact with magma or an igneous intrusion.Foliation refers to the parallel alignment of minerals or the development of compositional layering within a metamorphic rock. Volcanic igneous rocks are classified as extrusive igneous rocks because they are formed from lava that has extruded onto the surface.The process of lithification involves the transformation of loose sediments into solid sedimentary rocks.Compaction is a key process in the lithification of sedimentary rocks. It takes place as layers of sediment accumulate over time, and the weight of the overlying sediments exerts pressure on the underlying layers.

Thus, the correct blanks are Intrusive, Slow, deposited, cementation, Regional, Contact, Foliation, volcanic igneous, lithified, and Compaction.

Predict the most likely outcome of culturing transformed E. coli in the presence of tetracycline.Justify your prediction.

Answers

Answer:

E.coli is a bacterium which is preffered for transformation due to its rapid growth and high efficiency of introduction of DNA molecules into cells.

Tetracycline is an antibiotic used to treat several infections such as cholera, plague, brucellosis, and malaria etcetra.

Plasmid is a small, extrachromosomal DNA molecule present in cell which is seprated from chromosomal DNA and have ability to replicate independently.

When a plasmid resistant to tetracycline and kanamycine is inserted into E.coli, the process is called transformation. E.coli might not be able to survive due to absence of plasmid but the transformed strains having antibiotic tetracycline and kanamycine will probably be able to survive it.

Hence, the culture of bacteria carrying plasmid will be able to survive only.

Maximum transformation to tetracycline achieved when cells were harvested from L broth at 5.0-6.0 cfu/ml , followed by washing twice in cold.

The susceptibility of E.coli strain to culturing transformation by plasmid DNA was examined and optimized.

Transformation

Cells grown within the presence of D - cycloserine ( Cyc ) rather than Neg Gram (N x) transformed better. The presence of 5 mm Mg2+ ions in washing and CaCl2 solutions stimulated transformation about 2-fold.

Optimal conditions for transformation included a pH range of seven. 25-7.75 and a cell-to-DNA ratio of about 1.6 . 10(8) cfu/ng plasmid DNA.

The frequency of transformation was highest when cells were exposed to 100 mM CaCl2 in 250 mm.

Composition

[tex]\rm KCl + 5 mM \;MgCl2 + 5 mM \;Tris[/tex]

pH 7.6, before mixing with DNA

Therefore, the results of culturing transformed E.coli within the presence of tetracycline is justified.
