Leonard designed a parallel circuit to light two lightbulbs. But his circuit doesn’t work. Which two items in the circuit must b
tamaranim1 [39]

In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through each component.

If two or more components are connected in parallel they have the same potential difference ( voltage) across their ends. The potential differences across the components are the same in magnitude, and they also have identical polarities. The same voltage is applicable to all circuit components connected in parallel.

If each bulb is wired to the battery in a separate loop, the bulbs are said to be in parallel.

Organisms living in the deep bathypelagic and abyssopelagic zones require oxygen for respiration. What process brings oxygen fro
alekssr [168]

The correct answer is upwelling from equatorial to Polar Regions results in bringing oxygen from the epipelagic zone to deeper oceanic zones.  

It is a process in which the wind mediated motion of nutrient-rich, dense, and cooler water is moved towards the surface substituting the nutrient depleted and warmer surface water. The epipelagic zone refers to the upper layer of the ocean, which is abundant in oxygen and gets the majority of the sunlight for the procedure of photosynthesis. The upwelling of water from the equatorial to the polar region brings oxygen.

The central vacuoles of some plant cells you are studying fill with water and press the cell contents against their cell walls b
beks73 [17]

Answer:

The correct answers to the question are:

  • The concentration of solute bathing the inner side of the plant cell membrane should be high.
  • The concentration of solute bathing the outer side of the plant cell membrane should be low.

Explanation:

  • Turgidity can be defined as a condition in which the cell membrane of the plants cells becomes completely extended as a result of which it pushes tightly against the cell wall.
  • This happens when the cell takes up water from its environment and stores it in the vacuoles.
  • Water enters to the inside of the cell by the process of Osmosis.
  • Osmosis can be defined as the process by which molecules tend to move or diffuse from a region where its concentration is high to another region where its concentration is low, provided the two regions are separated by a semi-permeable membrane.
  • In any region, the concentration of solute and and concentration of solvent  bears an inverse relationship. This means that the region where the solute concentration is high, the solvent concentration is low and where the solute concentration is low, the solvent concentration is high.
  • In the given question, as the cell takes up water from the surrounding into its vacuole to become turgid, so by the concept of osmosis, the concentration of water must have been high outside the cell and low inside the cell.
  • Again by the inverse concentration concept of solute and solvent, the concentration of solute inside the cell should be more than the concentration of solute outside the cell.

Which of the factors likely contributed to the evolution of inducible defenses against herbivory? Select all that apply. a. diff
Triss [41]

Answer:

c. the cost to growth of allocating resources to defense

d. consistent fitness benefits of high allocations to defense

Explanation:

In order to ensure survival by  escape of  grazing and browsing by herbivores (and insects) plant usually adopt different defence mechanisms.This forms the basis for the optimum defence hypothesis .

The basic idea of the hypothesis is that the type   of  defence that an organism e.g plant  will adopt  against an herbivore depends on its fitness, and since this involve expenditure of energy it will be expensive for the organism to afford and maintain.
