Answer:
Contractile vacuole is responsible for maintaining the homeostasis in paramecium.
Explanation:
The observation of this experiment is that contractile vacuole is responsible for maintaining the homeostasis in paramecium because the contractile vacuole regulates the quantity of water inside a cell. Contractile vacuole controls the water balance in the body by absorbing and removing the excess amount of water out of the cell. This function of contractile vacuole allows the cells to survive under hypotonic stress that is present in the pond water or any other stressful environment.
First of all D does not make sense so you can roll that out right away yeah answer would be B
Answer:
Antigens
Explanation:
Antigens can be defined as molecules that can bind to antibodies. Many authors prefer to define it as any substance capable of eliciting a response from the immune system, however there are antigenic substances that react with the antibody but are not able to stimulate its production.
Antigens are usually unknown molecules in the body. Molecules that detach from foreign cells such as bacteria, fungi, protozoa or even viruses can be considered antigens. Toxins released by bacteria are also examples of substances that can bind to antibodies.
When an individual's blood-type alleles have instructions that direct the construction of a specific set of chemicals that protrude from all red blood cells, these chemicals are the antigens.
Answer:
taste and smell
Explanation:
triggers taste
example
hold your nose put a fruit candy in your mouth you will notice there will be a slight different taste
these molecules trigger basic taste
1) Identify the problem
2) Design a solution or product
3) Implement the design
4) Evaluate the product/solution
First start with making observations, and decide on the problem. You want to generate ideas, look and decide your limits, then create a solution or product. Then, build your product/solution, and put it to the test. Did it work? Identify the pros and cons of your product/solution, and decide what you could do better to improve your design.
