Describe how a disturbance changed forest ecosystems near Mount St. Helens

Biology
1 answer:
Sholpan [36]3 years ago

<u>At Mount St. Helens, erosion cut through the new volcanic deposits and exposed soil where plants could sprout. Thus in this disturbance, erosion was a positive process for plants, improving habitat. Lakes, streams, and forests responded at different rates after the 1980 eruption.</u>

A third species of kangaroo rat is introduced into the habitats of the two species from Question 5. If this third species is bio
DochEvi [55]

Both species would share both habitats because their niches would be different and competition would thus be eliminated.

A habitat is an area where an organism/species makes its home, which can be represented by all the resources present in that area. Conversely, a niche is the role of a particular species/organism within an environment. In consequence, a niche refers to the position of the organism/species within its community as a consequence of its adaptations, which is unrelated to the physical area it occupies.

In other words, the term habitat indicates how the environment impacts the organism/species while the term niche indicates how the organism/species impacts the environment.

Competitive exclusion indicates that two or more species can't have the same niche in a particular habitat and coexist. In this case, both species can coexist because they share habitats but their niches are different (it occurs when species have restricted diets and therefore their niches do not overlap).

How many CO2 molecules are produced when three glucose molecules undergo cellular respiration? Explan ​
Svetlanka [38]

Answer:

<u>18 molecules of </u>CO_{2}<u />

Explanation:

In heterotrophic nutrition, organisms ingest or absorb food made by autotrophs to obtain energy. Planta and other photosynthesizing organisms make sugars via photosynthesis, in a form of (partly) light-dependent biosynthesis.

In mitochondria, they break down sugars through aerobic respiration. For the sugar glucose, this results in the production of carbon dioxide and water along with energy in the form of ATP or adenosine triphosphate.  

C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP

glucose+ oxygen →  carbon dioxide+ water+ energy

For 3 molecules of glucose, multiply the number of reactants and products...

(C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP ) x 3

Thus...

3 C6H12O6+ 18 O2 → 18 CO2 + 18 H2O + ≅114 ATP

What modification to the Myosin light-chain protein by MLCP likely causes the contraction to relax?
Dafna1 [17]

Answer:

The options

A. Methylation

B. Dephosphorylation

C. Phosphorylation

D. Enzymatic transformation

The CORRECT ANSWER IS B.

B. Dephosphorylation

Explanation:

The regulation of the phosphorylation of myosin light chain (MLC) is a major step in the regulation of smooth muscle cell contraction.

The dephosphorylation of myosin light chain (MLC) occurs in smooth muscle tissue and causes the relaxation phase of the muscle cells. This step is controlled by the MLC phosphatase (MLCP).
