Answer:
Image result for Passive transport is the movement of substances across a cell membrane without the use of
Passive transport is a movement of ions and other atomic or molecular substances across cell membranes without need of energy input. Unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy.
Answer:
D. 70
Explanation:
From the table given, we can easily tell that distance (m) is dependent on time (s). Distance is a dependent variable, while time is an independent variable.
If both variables were to be plotted to show the relationship between them on a scatter plot, the dependent variable is usually plotted on the vertical axis (y-axis), while the independent variable would be plotted on the horizontal axis (x-axis).
Distance would be in the vertical axis, while time would be in the horizontal axis.
Therefore, the BEST choice for the top number of the scale on the vertical axis would certainly be 70, because the highest value for distance (m) on the table of values is 69.
Answer:
The immune system review. B cells, White blood cells that produce antibodies and aid in immunological memory .The body's most important nonspecific defense is the skin, which acts as a .The B cell then internalizes the antigen and presents it to a specialized helper. Innate immunity. Antigens are anything that causes an immune response. such as secretions, mucous, bile, gastric acid, saliva, tears, and sweat. General Immune Responses .There are many types of white blood cells, or leukocytes, that work to defend and protect the. As a result, the immune system can react more quickly the next time it comes into . These cells belong to the so-called cellular defense. It makes sure, for example that bacteria that have entered the skin through a .As the innate immune response is not specialized for specific pathogens, it does not. Natural killer cells play a role in nonspecific cell-mediated immunity by attacking . It launches a more potent secondary immune response . Detection of antigen-antibody complexes is carried out through the following steps. For some illnesses, such as measles and chickenpox, having the disease . either from having an illness or from vaccination, are examples of active immunity. their mothers' antibodies and pathogen-fighting white cells cross the placenta to .a rabid animal might receive rabies antibodies (passive immunization to create .
Explanation:
D. The nitrogen from the fertilizer made the plants grow too quickly,
which hurt the fish.
Explanation:
The best explanation for this result is that the nitrogen from the fertilizer caused the plants to grow too quickly and this hurts the fish.
This phenomenon is known as eutrophication.
Eutrophication is condition in which too much of nutrient is available in a water body.
- The presence of the fertilizer in the water body causes nutrient availability that causes more plants to grow in the water.
- The surge in the plant population will starve other life forms in the water.
- This is why the number of fishes will reduce.

Inherited traits are the traits that are passed on generation to generation, meaning you are born with these traits. And natural selection is the concept of "survival of the fittest" where the organisms with the best adapted traits in an environment live long enough to pass on that best adapted trait to their offspring.
