Lauren wants to know which location in her apartment is best for growing African violets. She has three African violets. She puts one on the balcony, one by the kitchen windows, and one on the mantel in the living room. Each plant has the same pot and the same soil, and Lauren gives each plant the same amount of water. Which is the independent variable?
Answer:
First, before determining which variable is which, we go over the definition of each. The independent variable is the one which is intentionally changed in order to investigate its effect on the dependent variable. The dependent variable is monitored and changes occur in it due to the changing conditions of the independent variable. In this case, the location of the African violets is the independent variable as it is intentionally changed, while the rate of growth of the African violets is the dependent variable as it is being measured.

What is not a part of the immune system?
A Mucous membranes
B Liver
C Skin
D Saliva
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.
Is Solid waste point source pollution or non point source pollution?
Answer:
Nonpoint-source pollution is the opposite of point-source pollution, with pollutants released in a wide area. As an example, picture a city street during a thunderstorm. As rainwater flows over asphalt, it washes away drops of oil that leaked from car engines, particles of tire rubber, dog waste, and trash. The runoff goes into a storm sewer and ends up in a nearby river. Runoff is a major cause of nonpoint-source pollution. It is a big problem in cities because of all the hard surfaces, including streets and roofs. The amount of pollutants washed from a single city block might be small, but when you add up the miles and miles of pavement in a big city you get a big problem.
In rural areas, runoff can wash sediment from the roads in a logged-over forest tract. It can also carry acid from abandoned mines and flush pesticides and fertilizer from farm fields. All of this pollution is likely to wind up in streams, rivers, and lakes.
Airborne pollutants are major contributors to acid rain. It forms in the atmosphere when sulfur dioxide and nitrogen oxides combine with water. Because acid rain results from the long-range movement of those pollutants from many factories and power plants, it is considered nonpoint-source pollution.

Which of the following best identifies a way in which organs in an organism are similar to organelles in a cell?
A. Both are made of tissues.
B. Both carry out specific functions.
C. Both carry out chemosynthetic reactions.
D. Both are found in single-celled organisms.
Answer:
A
Explanation:
Both are made of tissues.
The organs in an organism and organelles in a cell both are similar as they both are made up of tissue. Thus, option A is correct.
What is tissue?The tissue is defined as a group of cell added together to form a tissue present in body and plays a vital role in covering of all internal as well as external area and organs of body, hollow organs and body lines cavity.
The structure of epithelial cells are they combined together by fitted junctions as well as adhering junction and attached to extra cellular matrix.
Tissue is the compact structure of cell and later tissue combined together to form organ and than organ system is formed to perform various functions of the body.
Therefore,the organs in an organism and organelles in a cell both are similar as they both are made up of tissue. Thus, option A is correct.
