The correct word to fill the gap would be indirect.
In other words, an indirect survey makes use of evidence, such as the footprints left behind by animals, to follow animals that are difficult to track.
Ecological surveys are of 2 types:
Direct ecological surveys have to do with studying phenomena directly and recording whatever that is observed.
Indirect surveys involve an indirect way of studying phenomena. The signs left by phenomena are observed and logically used to make deductions about such phenomena.

Answer:
The correct answer is - C) all of the above.
Explanation:
The growth patterns of the plants such as ivy and pole beans depend and controlled by various physiological processes. These physiological process helps in the plants to grow in a particular direction so they can get nutrition and resources they require for their growth and development.
These processes are Gravitropism, phototropism, and thigmotropism. Gravitropism ensures that plant roots grow towards the soil so they can get water and other nutrients. Phototropism is the other process that allows the plant to move in the direction of the light so they can get enough light for the photosynthesis process. Thigmotropism is the process or defense mechanism that and movement by touch stimulus.
Bacteria has a hard time getting inside a dry egg. Washing eggs removes the bloom and allows bacteria into the egg. Washing eggs in cool water pulls bacteria in even faster
Answer:
Net membrane potential is equal to the difference of positive charge and negative charge existing at the inner and outer side of the cell respectively. Since outer negative charge is higher in concentration, the net membrane potential is negative
Explanation:
The cell membrane potential defined as the net difference of ion concentration existing at the inner and outer side of a cell membrane at nay instance.
When the cell is at the resting potential, the positive potassium ion starts accumulating at the inner surface of the cell membrane as it becomes favors positive potassium ion. This leads to development of negative potential at the outer side of cell membrane by the accumulation of negative ions or charges. Hence, a net negative potential membrane develops.
