A small, cold creek flows through a dense forest. The trees line the banks of the creek providing shade most of the day. Algae grow well only in a few areas of the creek that receive direct sunlight. Most of the food energy enters the ecosystem in the form of dead leaves that fall from the trees. A fire swept through the forest, burning all the leaves, but leaving the trees standing. This increased the amount of direct sunlight reaching the creek.
As a result of the fire, what increased in the creek? What type of succession will occur to open new available niches and resources?

Answers

Answer 1
I don’t know the second part, but algae growth will increase as a result of the fire
Answer 2

Succession is the series of changes in an environment which results into making the environment more favorable for the organisms to live in. Pioneer species in the succession after fire will be lichens, fungi, and bacteria.

What is Ecological Succession?

Ecological Succession is the process by which the species and habitat in an area changes over time. Succession is of two types depending upon the condition of the area which are Primary Succession and Secondary Succession. Primary succession is the succession in the area where no organism ever existed whereas secondary succession is the succession in the area where life has existed once but it has been destroyed due to catastrophic activity.

The pioneer species in this area are lichen, fungi, and bacteria. The establishment of organisms in a primary succession starts with the rocks or lava flow that has been hardened, then lichen goes on to the rocks and spews acid which dissolves the rock.

How are primary and secondary succession similar and how are they different?

Answers

Answer:

They are similar in that both involve the growth of new organisms in an environment. However they differ in that primary succession occurs in a place where no life had been before, while secondary succession occurs in place where life had been before, but was destroyed.

Some examples of primary succession include the formation of a new ecosystem after a volcano, glacier outbursts, or a nuclear explosion. Some examples of secondary succession include succession after fire, harvesting, logging, or abandonment of land or the renewal after a disease outbreak.

Answer:

In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.

Sometimes an organ can be replaced by moving it from one part of the body to another. This can be done, for example, to replace damaged skin or joints. In these cases: antigens would be generated against the transplanted organ. rejection of the transplanted organ would still be expected. antibodies would be generated against the transplanted organ. rejection of the transplanted organ would not be expected. immunosuppressant drugs would be required to prevent transplant rejection.

Answers

Answer:

rejection of the transplanted organ would not be expected

Explanation:

Transplantation refers to 1-the movement of an organ/tissue/cells from one part of a person's body to another part, and 2-the movement of an organ/tissue/cells from one individual (donor) to another individual (recipient). An autograft is a type of transplant by which a patient receives his/her own tissue. For example, a skin autograft consists of a patch of skin that is removed from one area of the body and transplanted to another body region of the same individual. Skin autograft is a relatively common transplantation process used to repair wounds and restore skin function. In rats, the mechanism of skin autograft rejection has been reported as uncertain. Moreover, transplant rejection is a natural mechanism by which the immune system of a person does not recognize the transplant as its own, thereby attacking the transplanted organ/tissue. The autograft rejection reactions are relatively uncommon but they depend on the type of organ/tissue/cells to be transplanted.

Answer:

To remove impurities.

Explanation:

Minerals are processed in order to remove impurities from the minerals as well as getting clean minerals. If the minerals are not clean from impurities, it can't be used in the manufacturing of other products. Tailings are the materials that left over after the process of separating the mineral from the uneconomic fraction or residue of an ore. Tailing stored in water can be dangerous sources of toxic chemicals, such as heavy metals, sulfides and radioactive content that can adversely affected the biotic or living part of water.

Transcriptional termination by RNA polymerase is favored when tryptophan levels are low (1) / high (2), because the low levels (3) / abundance (4) of charged Trp-tRNATrp causes the ribosome to quickly synthesize the leader polypeptide (5) / stall at the pair of Trp codons (6). This termination (7) / elongation (8) structure forms because the 3-4 stem loop (9) / the ribosome (10) allows region 2 to pair with region 3.

Explanation:

The additional Trp Operon function is gene expression attenuation. If tryptophan levels are high, RNA Polymerase endings of glutamate operone are favoured, since the excess of Trp-tRNATrp load causes rna to rapidly synthesise the lead polyprotein and region iii base pairs with cluster 4 and creates stepping chain structures which signal mrna cessation. Rest both options are wrong in regards to the glutamate operon amplification transmission termination mechanism.

6. formed from warm-water, shallow marine reef
7. has not undergone a lot of transport immature,
8. deposited close to the source
9. formed from terrestrial mud (riverbank deposits)
10. deposited on a beach

Answers

Answer:

(a): 7. and 8.

(b): 6.

(c): 9.

(d): 4.

(e): 10

(f): 1.  

(g): 2.  

(h): 5.  and 3.  

Explanation:

Sedimentary rocks are rocks generated from pre-existing rocks and/or once-living organisms. Arkose is a type of sandstone rich in feldspar (at least 25% of this mineral). Moreover, a rock containing coral fossils indicates that its depositional environment was located in warm tropical reef waters. Mudstone is a kind of sedimentary rock composed of clay (in this case, sediments continued to be deposited above the dinosaur footprints). The black shales are fine-grained sedimentary rocks composed of a mixture of clay (in this case, the pyrite crystals are used as an indicator of low oxygen). Symmetrical ripple marks in the sandstone indicate a marine environment where water motion was dominated by wave oscillations. Cross-bedding is a common structure of sedimentary rocks that form during deposition on inclined surfaces of bedforms (e.g., ripples and dunes). Sediment deposition in swamps is usually heavily vegetated and therefore they are rich in organic matter, while deeper swamp sediments are generally anoxic. Finally, cobblestones are naturally occurring cobble-sized stones formed from the flow of water and gathered from stream beds, while pebblestones are formed when water bodies hit the giant rocks in the rivers and lakes.

A new human species was found on a distant planet, whose genetic inheritance and process of reproduction is identical to that of humans on earth, however, their phenotypes are much different. You are tracking two phenotypes in this new species: eye shape and tail size. The single gene that controls eye shape (gene E) is unlinked from the single gene that controls tail size (gene T). Square eyes is the dominant eye shape and round eyes is the recessive eye shape. Long tail is the dominant tail size and short tail is the recessive tail size.
1. An individual of this new species is heterozygous for gene E and heterozygous for gene T. What is their genotype and phenotype? (Note, the ‘ / ‘ symbolizes the genotype of the two different homologs for a given chromosome, for example chromosome 5 homolog / chromosome 5 homolog, and ' ; ' separates different chromosomes for example 'chromosome 5 ; chromosome 8)
