Mutualism
Mutualism is a relationship
between organisms of two different species in which each benefits. From the
question given above, the relationship between the termites and the unicellular
organism can be described as mutualism because both organisms benefit from each
other.
It means there are more negatively charged particles on the inside of the membrane than on the outside. Hope this helps.
The correct answer is option C, that is, viruses.
An infection occurs when a foreign species moves inside the body of an individual and causes harm. The species utilizes the body of that person to reproduce, sustain itself, and colonize. These infectious species are called pathogens. The examples of pathogens are viruses, bacteria, prions, and fungi.
Of the given options, viruses are the smallest infectious agent. The viruses are basic particles, which must infect a host cell to reproduce and develop. Viruses utilize the host cells metabolic machinery to double themselves.
Answer:
The question is not well structured, the correct one is;
Look at the following statement. What word completes the second gap? Substances move by active transport from an area where they are __________ concentrated to an area where they are __________ concentrated
The answer is MORE
Explanation:
Substances move from one position to another in living systems. This movement of substances can either be passive (without energy) or active (require energy). Active transport of substances involves the movement of substances against their concentration gradient.
Ideally, substances move naturally from an area they are more concentrated to an area they are less concentrated but in active transport, the opposite occurs i.e. substances move from area that they are less concentrated to one that they are more concentrated, which is going up against the normal concentration slope/gradient. Due to this, energy in form of ATP is usually required by the cell to perform active transport unlike passive transport that occurs without energy input.
Exanples of active transport in living cells are exocytosis and endocytosis in some organisms. Based on this explanation, the first gap will be LESS while the second gap will be MORE.
