Answer : B
Explanation:
The liver is not a part of the immune system. The liver is an organ that plays a crucial role in detoxifying the body, producing bile to help digest fats and storing nutrients. While the liver indirectly supports the immune system by removing toxins from the bloodstream, it is not a part of the immune system itself.
Answer:
B. liver
Explanation:
The immune system is a complex network of organs, tissues, cells, and molecules that work together to defend the body against harmful pathogens, such as bacteria, viruses, fungi, and parasites.
A Mucous membranes: Mucous membranes are part of the immune system as they serve as a physical barrier that helps to trap and prevent pathogens from entering the body. They are found in various areas of the body, including the respiratory tract, gastrointestinal tract, and urogenital tract, and are lined with special cells that produce mucus and immune cells that help fight against pathogens.
B Liver: The liver is not directly part of the immune system. It is primarily responsible for detoxification, metabolism of nutrients, and production of important proteins, such as clotting factors. However, the liver does play a role in the immune response by filtering blood and removing pathogens, toxins, and other harmful substances from circulation.
C Skin: The skin is the body's largest organ and serves as a physical barrier against pathogens, preventing them from entering the body. Additionally, the skin contains specialized immune cells that help defend against pathogens that may breach the skin's barrier, making it an important part of the immune system.
D Saliva: Saliva, which is produced by salivary glands in the mouth, contains enzymes that can help break down food and also has antimicrobial properties that can help inhibit the growth of bacteria and other pathogens in the mouth. While saliva has some immune properties, it is not considered a primary component of the immune system.

Visible light telescopes
Infrared telescopes
Radio telescopes
Answer: gamma ray telescopes
Explanation: quizlet
Answer:
Visible light telescope need not to be placed to record electromanetic radiation
Electronmagnet ways are not recorded by visible telescopes.
Cyanobacteria, also known as blue-green algae, are a kind of bacteria found in many lakes. These organisms make their own food through photosynthesis. Small animals including mayfly larvae eat the cyanobacteria, and small fish such as yellow perch eat the larvae. The small fish provide food for larger fish, such as walleye.
Describe a model you could use to show the transfer of energy within the lake ecosystem. In your description of your model, make sure you include the position of each organism identified in the paragraph.
Answer:
the transfer of energy in a lake ecosystem is a food web. In this model, the cyanobacteria are at the bottom and they are eaten by mayfly larvae. which is the larvae and then eaten by small fish like yellow perch, which are in turn eaten by larger fish such as walleye. The food web would be represented by arrows, showing the flow of energy from one organism to another. Each organism has a specific position in the food chain, with producers at the bottom and top predators at the top. This model demonstrates how energy is transferred through different levels .
Explanation:
Cyanobacteria, formerly known as blue-green algae, are photosynthetic microscopic organisms that are technically bacteria. They were originally called blue-green algae because dense growths often turn the water green, blue-green or brownish-green.
Cyanobacteria are aquatic and photosynthetic, that is, they live in the water, and can manufacture their own food. Because they are bacteria, they are quite small and usually unicellular, though they often grow in colonies large enough to see. They have the distinction of being the oldest known fossils, more than 3.5 billion years old, in fact! It may surprise you then to know that the cyanobacteria are still around; they are one of the largest and most important groups of bacteria on earth.
