Answer:The short film Some Animals Are More Equal than Others: Trophic Cascades and Keystone Species opens by asking
two fundamental questions in ecology: “What determines how many species live in a given place? Or how large
can each population grow?” The film then describes the pioneering experiments by Robert Paine and James Estes,
in the 1960s and 1970s, which started to address them. Paine’s experiments on the coast of Washington state
showed that the starfish is a keystone species, having a disproportionately large impact on its ecosystem relative
to its abundance. Estes and colleague John Palmisano discovered that the kelp forests of the North Pacific are
indirectly regulated by sea otters, which feed on sea urchins that consume kelp. The presence or absence of sea
otters causes a cascade of direct and indirect effects down the food chain, which in turn affect the structure of
the ecosystem. These early experiments inspired countless others on keystone species and trophic cascades in
ecosystems throughout the world.

What does “denature” mean in terms of protein structure?
Explanation:
Denaturation, in biology, process modifying the molecular structure of a protein. Denaturation involves the breaking of many of the weak linkages, or bonds (e.g., hydrogen bonds), within a protein molecule that are responsible for the highly ordered structure of the protein in its natural (native) state.
2. Describe a situation in which unbalanced forces are acting on an object. What is the net force
on the object, and how does the net force change the motion of the object?
Answer:
The force is by putting the two same objects on both sides and the motion is the scale
The force is by putting the two same objects on both sides and the motion is the scale.
What do you mean by force?In physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull.
The normal force acts in a direction normal to the surface interaction between objects. Friction is a force that opposes motion on surfaces. Other examples of non-fundamental forces include the elastic force, tension.
Force is the fundamental result of an interaction between two objects, while power is an expression of energy consumed over time (work), of which force is an element.

how might toxicology be important to other biomedical professions outside of forensics?
Answer: See explanation
Explanation:
Toxicology is a field in science that has to do with the effects of poisons, toxics and how they can be treated. Through toxicology, one can understand how harms are caused by chemicals and the health of the public can be protected.
Toxicologists study chemicals, drugs and other substances, and looks at how safe they're and their impact on living organisms. Toxicologists help in the development of methods that'll be used to know the harmful effects and the the dosages which causes it.
Furthermore, toxicology gives vital information and knowledge which the decision makers or regulatory agencies
in other biomedical fields can use in order to put programs in place that can be used to limit the exposures of humans to the substances.
In conclusion, less exposure to these substances is vital so that diseases can be prevented.
Toxicology is also used in the field of environmental health.
Toxicology will be important to other biomedical professions outside of forensics. Toxicology can be used in environmental health field which provides critical information and knowledge about the toxic substances that can be used by regulatory agencies to limit our exposures to toxic substances so we can say that toxicology plays an important role for other biomedical professions.

what is carrying capacity? what type of population growth does it affect?
Carrying capacity is referred to a population size of species in a particular habitat. In an ecosystem, the population of a species will increase till it reaches its carrying capacity. Then the population size remains relatively equal.
What are the types of carrying capacity?Carrying capacity is the maximum limit till that the ecosystem can support the existence of the population.
There are four categories of carrying capacity, namely:
Physical.Ecological.Economic.Social.A specific environment's carrying capacity is the maximum population size that it can support.
The carrying capacity modifies the growth rate by slowing it when resources become scarce and stopping growth once it is reached.
Thus, it can be concluded that the carrying capacity is the average population size of species in a particular habitat which slows and stops the growth rate on reaching it.
