E)
Answer: A, E
Explanation: I took the USA Test Prep and the person above me who commented said so.
An animal engaging in commensalism is as basic as a bird building a nest in a tree. Without being considerably injured or influenced by the bird, the tree offers the bird shelter and protection. Thus option A, E is correct.
What defines about Commensalism symbiotic relationship?A symbiotic relationship known as commensalism occurs when one species benefits while the other is unaffected. Usually, one species exploits the other for something outside food. For instance, mites will cling to larger flying insects to “hitch a ride.” Hermit crabs live in the dead snails' shells.
A relationship between members of two species when one species receives food or other benefits from the other without endangering or helping the latter. Commensalism.
Therefore, A bird builds a nest in a tree and A remora attaching itself to a shark obtaining transportation, shelter, and food scraps from the shark.

Why might it be harder to convince people of the value of forest ecosystem services as opposed to the value of it's economic service?
Answer:
It might be harder to convince people of the value of the forest ecosystem services as opposed to the value of its economic service because truthfully, people have different ideas on what is important and what´s not. So some people may think that the forest has no worth and it doesn´t matter to them if it gets torn down or not, as long as it makes them money, but others may feel that a forest is a special place where animals and such have a place to be free. In the end, it´s always about money and morals. I hope this helps!!

Which of the following helps protect biofilms from issues such as drying out and predators
a.) Extracellular polymeric substances
b.) Quorum sensing
c.) Becoming sessile
d.) Autoinducers
Extracellular polymeric substances help protect biofilms from issues such as drying out and predators. Option A
Biofilms are complex communities of microorganisms that adhere to surfaces and form a protective matrix. They can be found in various natural and artificial environments, such as riverbeds, medical devices, and plumbing systems. Biofilms provide advantages to the microorganisms within them, including protection from environmental stresses and predators.
One of the key components that helps protect biofilms is extracellular polymeric substances (EPS). EPS are complex mixtures of polysaccharides, proteins, and DNA that are secreted by microorganisms within the biofilm. These substances form a matrix that encases the cells, providing structural support and protecting the community.
EPS help biofilms resist drying out by retaining water and preventing desiccation. The polysaccharides in EPS can absorb and retain moisture, creating a hydrated environment within the biofilm even in dry conditions. This is crucial for the survival of the microorganisms within the biofilm.
Additionally, EPS serve as a barrier against predators. The matrix formed by EPS can make it difficult for predators, such as protozoa or grazing organisms, to access and consume the microorganisms within the biofilm. It acts as a physical defense mechanism, limiting the exposure of the microorganisms to predation.
While quorum sensing, becoming sessile (immobile), and autoinducers are all important mechanisms and processes associated with biofilms, they do not directly address the protection of biofilms from drying out and predators. So Option A is correct.

Before Darwin's theories, scientists thought that species….
O never changed
O Changed over time
O Changed only randomly
Answer:
Never changed.
Explanation:
Before Darwin's theories, scientists thought that species never changed. This concept was commonly known as the doctrine of "fixity of species," which posited that species were immutable and remained unchanged since their creation. According to this belief, species were considered to be fixed entities with no potential for an evolutionary change or adaptation to their environment. This view was deeply entrenched in the prevailing scientific and religious beliefs of the time, and it was not until Darwin's groundbreaking work on natural selection and the theory of evolution that this long-held notion was challenged and replaced with the understanding that species do indeed change over time through the process of natural selection and other mechanisms of evolution.
