The skin is made up of tissues with different functions that work together. So, the correct option is (C).
What is Skin?Skin is defined as the largest organ of the body where skin and its derivatives such as hair, nails, sweat and oil glands form the integumentary system. The main function of the skin is protection which protects the body from external factors such as bacteria, chemicals and temperature.
The skin is made up of water, proteins, fats and minerals that protect the body from germs and regulate body temperature. Skin nerves help to feel sensations like hot and cold.
It is made up of three layers, the epidermis, dermis and hypodermis which are anatomically distinct. Its structure is made up of a complex network that serves as the body's initial barrier against pathogens, UV light and chemicals, and mechanical injury.
Thus, the skin is made up of tissues with different functions that work together. So, the correct option is (C).

A mouse had a gene sequence of GTT coding for leucine, an amino acid.
mutation in this gene led to the formation of GTG. However, the amino acid formed was leucine, despite the mutation. This is a
mutation for the mouse.
The mutation that occurred in the mouse is a silent mutation since it does not affect the amino acid sequence in the protein.
What is a mutation?A mutation is a change that occurs in the sequence of nucleotides in the DNA of organisms.
A mutation can either have deleterious effect on the organism or have no effect at all. Mutations that do not have any effect on the organism are known as silent mutations.
Silent mutations do not affect the sequence of amino acids that make up a protein.

consists of all, EXCEPT which
of the following?
A. a simple brain with a nerve cord
B. pores in the skin for food to move in and a stomach in each
segment
C. longitudinal and circular muscles for movement
D. a heart of aortic arches and vessels along the body
An earthworm's body plan consists of all, EXCEPT pores in the skin for food to move in and a stomach in each segment. Thus, option "B" is correct.
What is an earthworm's body plan?The physique of the earthworm is segmented which appears like numerous tiny rings combined or merged collectively. The earthworm is made of around 100-150 segments. The segmented body portions deliver significant organizational purposes.
Segmentation can help the earthworm move. Each segment or piece has muscles and bristles named setae. The bristles or setae support the anchor and govern the worm when stirring over the soil. The bristles grasp a segment of the worm definitely into the ground while the other portion of the physique projects forward.
The earthworm uses parts to either contract or relaxes self-sufficiently to source the body to grow in one area or contract in other areas. The division supports the worm to be supple and sturdy in its drive. If each section stimulated collectively deprived of being self-governing, the earthworm would be stationary.
Thus, option "B" is correct.

Explanation:
Blood sugar is too high. Pancreas releases insulin to stimulate the liver and store glucose to break down sugar from the blood and store it as glycogen or glucose. Blood sugar levels decreases.
Blood sugar level is too low. Pancreas releases glucagon to stimulate the glucose production in the liver and maintain adequate plasma glucose concentrations to convert stored glucagon and fat back into glucose to be released in the blood. Blood sugar levels increases.

Rabbits were introduced to Australia by humans and have caused severe disruptions to the natural ecosystem. How would you classify these rabbits?
The rabbits would be classified as exotic invasive species.
What are invasive species?Invasive species are plant or animal species that disrupt the ecological balance of ecosystems by their invasive attributes.
Invasive attributes include the ability to spread or multiply at a fast rate, sometimes secreting biological chemicals to inhibit the growth of other species.
Exotic invasive species are invasive species that are introduced, rather than being native to the ecosystem.

Staphylococcus aureus, or staph, is a bacteria that is commonly found in the nose and on the skin of humans. While it is typically not harmful to humans, it is sometimes able to enter the body through an injury or broken skin, and get into the bloodstream. When this happens, it can cause a serious infection called sepsis. Sepsis can cause an individual to go into shock and bodily organs to stop functioning. Symptoms of sepsis include inflammation, fever or hypothermia, increased heart rate, and rapid breathing.
A microscopic image of staphylococcus aureus is shown.
Which immune system component initially results in the inflammation and responds quickly when Staphylococcus aureus enters the bloodstream?
complement system
phagocytes
Langerhans cells
B lymphocytes
