Section 3: For at least one of the sub-problems, propose two solutions based on the information from the lesson and your additional research. In the rationale column, explain how your solution restores the stability and biodiversity of your selected ecosystem.

Answers

Removal of invasive species and growing more vegetation can restore the stability and biodiversity of ecosystem.

These two solutions restores the stability and biodiversity of the selected ecosystem because invasive species can capture more resources as compared to local species which leads to the extinction of local species.

While on the other hand, growing more vegetation provides more food to the organisms which ultimately increases the biodiversity of the ecosystem so we can conclude that removal of invasive species and growing more vegetation are the solutions to bring ecosystem in a stable condition.

in cells regulation allows rapid response to changes in the environment; in cells, gene regulation is critical for maintaining homeostasis.

Answers

Given what we know about biological mechanisms, we can confirm that both of these statements are in fact true in regards to regulation and gene expression.

Homeostasis is the body's ability to maintain constant a series of processes and values that we need in order to survive. To do this, regulation in cells is essential. Regulation allows us to respond rapidly to changes in the environment by regulating the processes which control the homeostasis for that environmental change.

Gene regulation or expression is another way in which the body maintains homeostasis. For example, in the presence of too much substrate, the gene encoding a specific enzyme might activate, causing the creation of the enzyme and getting substrate levels back to normal.

Inversely, if the body detects that substrate levels may be too low, the expression of any gene that may consume that substrate can be silenced, therefore maintaining a balanced level.

Which of the following is a binocular cue for depth perception?.

Answers

Where is the picture ?

A binocular cue used to assess depth between two nearby objects is called retinal disparity.

What is the binocular cue for depth perception?

The pictures that both eyes focus on to create stereopsis, or the feeling of depth, is known as binocular depth cues. Using binoculars, one may see the world in three dimensions.

Binocular depth signals can be classified as either retinal disparity or convergence. Convergence centers on a single object while using both eyes.

A binocular cue used to assess depth between two nearby objects is called retinal disparity. It accomplishes this by contrasting the various pictures from the two retinas. Because the distance between each eye is typically around two and a half inches, each eye sees different pictures.

Therefore, the retinal disparity is a binocular cue for depth perception.

When someone invests in a product, they do not aim to use it for immediate consumption but rather as a means of generating money in the future.

An investment always entails the use of some resource today, such as time, money, effort, or an item, with the hope of receiving a return that is higher than the initial investment. An investor might, for instance, purchase a financial asset right away in anticipation that it would generate income over the road or be able to be sold for a profit at a higher price.
