Identify one organism, one population, and one community
Answer:
The study of organisms, populations and communities examines how organisms interact with each other and their environment at individual, population and community levels. To characterize these interactions, NEON quantifies and observes interactions among multiple organisms and their environments. By sampling a variety of organisms in aquatic and terrestrial systems, NEON provides data on individual traits, population dynamics and the composition of communities. Integrated with other data collected across NEON sites, the project produces data in the areas of biodiversity, infectious diseases and invasive species.
Some scientists predict that if global warming continues over the next few centuries, melting of the polar caps will raise the level of the oceans, causing some peninsulas to become islands. How might this change eventually affect the species that live on these peninsulas
Considering the connections between Yellowstone’s wolves, aspen and willow trees, and elk; which one is the keystone species.
Answer:
The keystone species is the wolf.
Explanation:
Every species of organism is important to the ecosystem, so if just one species gets extinct for whatever reason there will be consequences for the other species. How big the consequences will be, depends on the species and on how big of an effect it has on the ecosystem. Some species have relatively small importance, while some have huge importance, and the ones that have huge importance are called keystone species.
The keystone species have such big importance to an ecosystem that with their presence everything is under control, but if they go extinct then the ecosystem suffers badly and changes dramatically. In this case, a keystone species is the wolf. The wolves control the elk population, which in turn means that there is no shortage of food for the elk and they don't damage the young trees. By not damaging the young trees, they grow, so there is a much larger area covered by forest. More forest means less erosion, the water of the streams is better controlled, and there is less meandering. If the wolves are out of the picture, as they were for some time, the picture is totally opposite.
Why do we need the brazilion forest
Answer:
We need the Brazilian forest because it produces roughly six percent of the world's oxygen and has long been thought to act as a carbon sink.

Fa person's croulatory system did not function properly, how might
other systems, such as the respiratory and digestive systems, be
affected? How would homeostasis, or internal stability, be affected by
these system imbalances?
Answer:
If the circulatory system does not function properly, the blood supply to the organs in the digestive and respiratory systems is altered, resulting in a decrease in the supply of nutrients and oxygen required by the tissues. When the tissues do not receive the adequate amount of nutrients and oxygen to fulfill their functions, a negative alteration of the internal balance or homeostasis is produced.
Explanation:
The circulatory system is responsible for providing blood supply to all tissues and organs of the body. A circulatory system that does not work properly already means an inadequate supply of nutrients and oxygen to the organic tissues.
How does an altered circulatory system affect other systems, such as the digestive and respiratory systems? Respiratory system: it is in charge of providing oxygen (O₂) to the body, through lung breathing and gas exchange. When there is little blood supply, this system decreases its function, thus reducing both the supply of O₂ to the tissues and the elimination of carbon dioxide (CO₂). Digestive system: responsible for the digestion and absorption of nutrients, a function that can be altered when there is not adequate blood circulation. The supply of nutrients to tissues, already compromised by poor circulation, may be insufficient for cellular and tissue demand. How does an altered circulatory system affect homeostasis?The internal balance or homeostasis depends on the normal functioning of all the organic systems. If the circulatory system does not adequately fulfill its function, the tissues and organs do not receive the proper amount of O₂ and nutrients, a deficit that can lead to an alteration of homeostasis.
Vesicles that serve to break down cellular debris
Answer:
Lysosomes are vesicles that are formed by the golgi apparatus. They contain powerful enzymes that could break down (digest) the cell products, waste materials , and cellular debris and then force them out of the cel. They also digest invading organisms as bacteria.

Compare and contrast the TWO classes of "seeded "plants.
Answer:
The seed plants are often divided arbitrarily into two groups: the gymnosperms and the angiosperms. The basis for this distinction is that angiosperms produce flowers, while the gymnosperms do not.
Explanation:
The seed plants are often divided arbitrarily into two groups: the gymnosperms and the angiosperms. The basis for this distinction is that angiosperms produce flowers, while the gymnosperms do not. This is poor form, since it defines the gymnosperms by the absence of a character, and not by any features that the organisms actually share. The gymnosperms do share a number of features, but, as should be obvious from the above cladogram, they are not more closely related to each other than to the angiosperms (Anthophyta). The features shared by gymnosperms were likely present in the early ancestors of the flowering plants as well. It should also be noted that the "progymnosperms" are represented by a box of a different color, in order to make it clear that they are not actually seed plants, but rather are included here because they are believed to be the closest relatives of the seed plants.
Systematics within the seed plants is poorly understood. Part of the problem is that most of the major groups have gone extinct, and several of the groups alive today consist primarily of plants with highly derived morphologies. The above cladogram is based largely on the work of Jim Doyle, a professor at UC Davis, and Michael Donoghue, currently at Harvard, and is therefore somewhat preliminary. It includes some questionable groupings not explicitly supported in their papers.
Parelaphostrongylus tenuis is a parasitic brain worm that infects members of the Cervidae family, such as deer and moose. The worm's most common host is the white-tailed deer which lives in
pulation density, climate and an individual's resistance to the parasite. Most deer populations have evolved a resistance
to the fatal effects of the worm but still carry the parasite. As Earth's c
quently in mouse populations. How will the moose populations be impacted by these changes?
Moose populations would decrease as the moose emigrate to safer habitats
Moose populations would increase since the moose and deer can breed creating resistant moose.
Moose populations would decrease as the worm is a biotic factor that will limit the growth of their population
Moose populations would increase as weak moose are killed allowing stronger moose to give birth or immigrate into the area.

Moose populations would increase as weak moose are killed allowing stronger moose to give birth or immigrate into the area.

The diagram below shows two different forces acting on a cyclist riding a bicycle the total mass of the cyclist and the bicycle is 100.0 kg based on information what is the acceleration of the cyclist?
Answer:b
Explanation:
The diagram below shows two different forces acting on a cyclist riding a bicycle is 150 N and another force acting opposite to moving cycle is 84 N the total mass of the cyclist and the bicycle is 100.0 kg based on information. Thus, option B is correct.
How net force will be calculated?
The net force acting on the bicycle is:-
F net = Total force acting on bicycle
In above question,
Given the F1 = 150 N and F2 = -84 N (Negative sign shows that force is acting opposite to the motion)
So,
Fnet = F1 + F2
Fnet = 150 N -84 N
Fnet = 66 N
Now the acceleration will be
Fnet = mass X acceleration
In above question,
Fnet = 66 N
Mass = 100 Kg
So,
Acceleration = Fnet/Mass
Acceleration = 66/100
Acceleration = 0.66 m/sec^2
Therefore, The diagram below shows two different forces acting on a cyclist riding a bicycle is 150 N and another force acting opposite to moving cycle is 84 N the total mass of the cyclist and the bicycle is 100.0 kg based on information. Thus, option B is correct.

what is an important step in the process of translation?
Answer: There are three major steps to translation: Initiation, Elongation, and Termination. The ribosome is made of two separate subunits: the small subunit and the large subunit. During initiation the small subunit attaches to the 5' end of mRNA. It then moves in the 5' → 3' direction.
