The functions of the integument include resident macrophage-like cells that ingest foreign invaders and present them to the immune system.
What is the integumentary system?The integumentary system is a physical barrier that separates the body from the external environment.
This barrier (integumentary system) is fundamental for the immune system due to the presence of macrophage-like cells.
In conclusion, the functions of the integument include resident macrophage-like cells that ingest foreign invaders and present them to the immune system.

What is a feedback mechanism?
What is a feedback mechanism?
A feedback mechanism is a physiological regulation system in a living body that works to return the body to its normal internal state, or commonly known as homeostasis. In nature, feedback mechanisms can be found in a variety of environments and animal types. Feedback occurs when outputs of a system are routed back as inputs as part of a chain of cause-and-effect that forms a circuit or loop. The system can then be said to feed back into itself.
Examples:
Menstrual cycle. At the beginning of the menstrual cycle, the ovaries release the hormone estrogen. The estrogen acts as a stimulus for the positive feedback loop. ...Childbirth. Figure: Normal childbirth is driven by a positive feedback loop.
The images show two different types of Galapagos tortoises that scientists believe descended from the same species. The first type (left) are found on islands that have high vegetation and few grasses. The second type (right) are found on an island that has large amounts of grasses and low-lying shrubs. What explains the type of turtle found on the islands with high vegetation?
A.
The environment triggered a gene mutation in neck length in order to help the turtle survive.
B.
Mutations are random, so it is by chance that turtles with longer necks live on these islands.
C.
Turtles with genes for long necks had a better chance of surviving to reach reproductive age.
D.
Turtles with short necks completely lacked adaptations for finding food, so they died off.
Turtles with genes for long necks had a better chance of surviving to reach reproductive age due to ability to reach the food source.
What type of turtle survive on the Island?Turtles with genes for long necks had a better chance of surviving to reach reproductive age because the long neck enables the turtles to reach the food source that is present on a certain height. So they are able to survive and complete its life cycle.
So we can conclude that option C is the right answer.

Estrogens are hormones that are play important roles in the reproductive system.
What are the roles played by estrogen?The environmental estrogen introduced to the male cells has the ability to recognise the binding sites of the receptors on the male cells.
They are able to attach the the cell membranes by its ability to bind to the cell receptors.
When the binding occurs, there would be a conformational change within the cell leading to:
