Coupled transporters that move solutes in the same direction are called _______.
The coupled transporters that move solutes in the same direction are called symport.
Three means of transport are present in living cells- diffusion, facilitated diffusion, and active transport.
In facilitated diffusion, the movement of solutes occurs through special transport proteins.
These proteins form channels inside them to facilitate the transport of solutes through them.
Depending upon the direction of movement of solutes, facilitated diffusion is further of three types
Symport - In this case, two solutes move together in the same direction.
Antiport - In the case of antiport two solutes move together in the opposite direction.
Uniport - When a solute moves across the membrane independent of the movement of other solutes it is known as uniport.

You are testing the hypothesis that increased population density of a particular plant species increases the rate at which a pathogenic fungus infects the plant. Because the fungus causes visible scars on the leaves, you can easily determine whether a plant is infected. Design an experiment to test your hypothesis. Describe your experimental and control groups, how you would collect data, and what results you would see if your hypothesis is correct.
Hypothesis was correct, there is a direct relationship between the number of plants in a population, i.e. a higher density, and the rate of infection--the greater the plant population, the faster the rate of pathogenic fungal infection, the lesser the amount of plants, the lesser the rate of infection.
Briefing:Before any experiment start with a hypothesis. In this instance, the degree of fungal infection and the population of plants are inversely correlated.
Thus, the more plant density, the more plants available to be infected by the fungus. If there is a lesser plant density, there will be less plants available to infect, thus a LOWER rate of fungal infection on these plants.
The experiment:Control: Place 5 plants in an environment held at room temperature (there is no pathogenic fungus in the environment, just plants--as a result, the plants will grow, showing no damage of leaves ie no infection.
For each of the following groups, place in an environment held at room temperature for 3 days, on the third day, record the amount of leaves that show damage (evidence of fungal infection).
Group 1
Place 1 plant, 1 fungi
Result, the lowest rate of infection (number of damaged leaves) (2 infected leaves)
Group 2

Explain how people can become obese even if their intake of dietary fat is relatively low compared with carbohydrate intake.
Let's assume that dietary fat consumption is lower than that of carbohydrates. People will then be more likely to be overweight or obese since a low-carbohydrate diet that derives less than 47% of its energy from carbohydrates increases the risk of obesity.
The body stores extra calories as body fat and stores the remaining energy as glycogen or fat in the muscles, liver, and other organs for later use.Following a meal with too many calories, which could lead to weight gain or being overweight, this body fat is extended over time. Foods that are high in fat, carbohydrates, or proteins can provide the extra calories.Obesity and the expansion and enlargement of cells are both possible outcomes of the buildup of excessive adipose tissue.Obesity may occur from an excessive triacylglycerol buildup. When eating less and exercising more to lose weight, calorie fat must be produced in order to reduce the quantity of stored fat in cells.The excess fat is stored as body fat and is deposited in the muscles and liver.

Which of the following is true with respect to oligotrophic lakes and eutrophic lakes? a. Oligotrophic lakes are more subject to oxygen depletion. b. Rates of photosynthesis are lower in eutrophic lakes. c. Eutrophic lakes are richer in nutrients. d. Sediments in oligotrophic lakes contain larger amounts of decomposable organic matter.
The correct option is (c) Eutrophic lakes are richer in nutrients.
Eutrophic lakes feature high concentrations of plant nutrients, such as nitrogen and phosphorus, and therefore sustain high plant productivity.
They are generally more nutrient rich than oligotrophic or mesotrophic lakes. Two times a year, in the spring and the fall, dimictic lakes change. This re-mixes the nutrients and dissolved oxygen that the lake's plants and creatures need. The top water cools and gets denser in the fall than the bottom waters do. The lake water is mixed as the cooler water sinks to the bottom. As the temperature drops in the winter, ice builds up on top of the lake and prevents any more mixing. When the lake is heated by the sun in the spring, the cooler, less dense water rises to the surface while the warmer, denser water sinks. The temperature and density disparities between the upper and bottom water layers grow increasingly pronounced as the summer goes on. In the summer and winter, these lakes typically physically stratify into three discernible strata.Learn more about the Eutrophic lake with the help of the given link:

In the autonomic nervous system, neurotransmitter activation of its receptor terminates when the neurotransmitter is broken down by enzymes or when it diffuses away. Which other mechanism leads to termination of neurotransmitter activity?.
Active transport into surrounding cells can lead to termination of neurotransmitter activity.
Neurotransmitters are released into the synapses to forward the signals to the receptors of the postsynaptic neurons. These neurotransmitters need to be cleared off to forward new signals. Three mechanisms can be followed to terminate these neurotransmitters in order to introduce new neurotransmitters: diffusion, degradation, and reuptake.
Diffusion
Neurotransmitters in the synapses move until the concentrations are equal. Example- Nitric oxide
Degradation
Neurotransmitters can be broken down by the action of enzymes in order to clear off the synapses. Example- Acetylcholine
Reuptake
Neurotransmitters can also be recycled. In this mechanism, the presynaptic neuron introduces a protein into the synapse that pushes the neurotransmitters against the concentration gradient to push it out of the cell membrane. Examples include glutamate.
Therefore, in the autonomic nervous system, neurotransmitter activation of its receptors terminates when the neurotransmitter is broken down by enzymes, or when it diffuses away, or when it is pushed against the concentration gradient through active transport.
