Which condition is necessary for enzymes and hormones to function properly in the human body?
Enzymes can only work in certain conditions. Most enzymes in the human body work best at around 37°C – body temperature. At lower temperatures, they will still work but much more slowly. Similarly, enzymes can only function in a certain pH range (acidic/alkaline).
Which structure normally stimulates an allergic response?
In an allergic response, an allergen stimulates the release of antibodies, which attach themselves to mast cells. Following subsequent allergen exposure, the mast cells release substances such as histamine (a chemical responsible for allergic symptoms) into the tissue.
What do Vaccinations usually stimulate the body to produce more of?
The vaccine stimulates the body to produce antibodies against the antigen in the vaccine. The antibodies created will be the same as those produced if the person was exposed to the pathogen.
Which compound that directly provides energy?
ATP
Which statement best describes a situation where competition occurs in an ecosystem?
Considering this, the statement that describes a situation of competition in an ecosystem is “A deer and a rabbit consumes grass in a field ” because in this case two species need the same resource and if this is limited a struggle or fight for this resource can take place.
Which cell structure is mainly responsible for releasing energy?
MITOCHONDRIA
Which statement best describes what would most likely be observed after 20 minutes?
The statement that describes the observation after 20 minutes would be that the contents of the dialysis tube would turn blue-black. this is because the starch would diffuse from the solution in the beaker to the water inside the dialysis tube to attain equilibrium.
Which cell structures are correctly paired with their functions?
4 Which cell structures are correctly paired with their functions? (1) The mitochondria produce enzymes, and ribosomes transport them. (2) The ribosomes make proteins, and the nucleus stores genetic information. (3) The cell membrane makes enzymes, and cytoplasm transports them.
Which two cell structures work together?
The answer is (3) nucleus and ribosome.
What is the main function of a vacuole in a cell?
Vacuole. A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance.
What is the job of the Golgi?
A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell. Named after its discoverer, Camillo Golgi, the Golgi body appears as a series of stacked membranes.
What will happen if Golgi body is removed from the cell?
If the Golgi apparatus is removed from the cell, all sorts of vesicle formation will stop. The Golgi apparatus is mainly responsible for transporting, modifying, and packaging of proteins and lipids into vesicles to be delivered to targeted destinations.
What are the two main functions of the Golgi apparatus?
A major function is the modifying, sorting and packaging of proteins for secretion. It is also involved in the transport of lipids around the cell, and the creation of lysosomes. The sacs or folds of the Golgi apparatus are called cisternae.
What is a real life example of Golgi apparatus?
The Golgi Apparatus is like a small packaging system. It’s particular function, is to store/package protein enzymes and carbohydrates before they are sent to a location. An example of the Golgi Apparatus is a postal office. A postal office packages and sends mail to different locations.
What is an example of cytoplasm in real life?
It is made up mostly of water, salts, and proteins. The cells within your own body, and within plants contain cytoplasm. So two real life examples of cytoplasm would be the fluid in your own cells, and the fluid inside the cells of a tree.
What is cytoplasm like in real life?
The cytoplasm is like a jello salad because the cytoplasm surrounds and suspends the cell’s organelles like the jello surrounds and suspends the fruit in the jello salad.
What is an example of ribosomes in real life?
Ribosomes are great. One of the most common real-life examples of their use is preparing a surface for painting. Did you know that painters generally spray down the exterior of a house with ribosomes before applying the first coat, so the paint will stick better? Another common use is as a pet toy.
What are ribosomes like in the human body?
The ribosomes is like the production of proteins. So compared to our body is like the stomach which is where we get our protein. The ribosomes produce protein and send them to the places in the cell that needs it.
What everyday object is like a cell membrane?
Cell Parts Analogy. The cell membrane controls what goes in and out of the cell. The cell membrane is like a screen door, because a screen door holds things out but lets air in.
What household item is like a mitochondria?
Battery
