Which of the following is not a characteristic of pioneer species ?
Irina-Kira [14]

Answer:

They remain in an environment,even as more competitive species arrive

Explanation:

Pioneer species, in ecological succession, are the first set of organisms to colonize a bare area of land or a disturbed area of land. Pioneer species include lichens, grasses, fungi etc.

Pioneer species have unique characteristics that distinguishes them from every other species of organism. These include:

- They facilitate environmental change, making an environment more habitable for other species.

- They tolerate a wide range of environmental conditions.

- They are capable of colonizing a barren environment, as in primary succession.

However, pioneer species do not remain in an environment, even as more competitive species arrive. They rather give way for new species to emerge and dominate.

How many consumers are omnivores in the food web below?
lord [1]

Answer:

1

Explanation:

Omnivores are animals that eat both plants and animals. If you look at the bottom of the food web, you need to look for arrows that point towards an animal that also consumes other animals. The arrows indicate that the energy is being transferred from the plants to the omnivore. The Raccoon is the other organism that eats both a producer (blackberries) and other predators such as garter snakes and meadow voles.

Human red blood cells that lack sufficient hemoglobin would have a low amount of what substance?
lisabon 2012 [21]

If a human’s red blood cells will lack sufficient amount of hemoglobin, he or she would have also a low amount of oxygen.

Hemoglobin is what makes the red blood cells red in color, aside from the abnormal color, the red blood cells also make up of oxygen.  It can also be with iron since iron is bind to hemoglobin all the way to the lungs.

The solutions in the two arms of a U-tube are separated by a membrane that is
IgorC [24]

Answer:

See the answer below

Explanation:

Recall that: <em>Water potential = pressure potential + solute potential</em>

Since the system is an open one;

<em>Water potential = solute potential = -iCRT</em>

i = number of particles the molecle will make in water (1)

C = molar concentration

R = Pressure constant = 0.0831 liter bar/mole K

T = temperature in kelvin = 22 + 273 = 295 K

To calculate water potential on side A:

C = 1 M

Water potential = - (1 x 1 x 0.0831 x 295) = -24.51 bars

For side B:

C = 2 M

Water potential = - (1 x 2 x 0.0831 x 295) = -49.03 bars

b.

<em>Since side A has higher water potential than side B, water will flow from side A to side B until equilibrium is established between the two sides. Water always flows from the region of higher water potential to the region of lower water potential.</em>

You use two drugs (sulfisoxazole and trimethoprim) to treat a bacterial infection and notice that bactericidal activity is enhan
mezya [45]
Antagonsitic effect/interaction/response

In order to combat antiobiotic resistance, and to possibly enhance the activity of antibiotics, they are sometimes used in combinations during treatment. However, three possible responses or effects can manifest. 

First is antibiotic synergy, where the combined effect of the antibiotics enhances the activity/potency of the treatment compared to when the antibiotics are administered singly.

The effect is also distinguished from another type of response, which is additive effect, where the combined effect of the antibiotics is more or less equal to the combined activity/potency of each of the antibiotic when applied singly. Antibiotic synergy results in even greater enhancement of the activity of the combined antibiotics compared to additive effect. 

Lastly, there is the antagonistic effect or response, where the combined effect of the antibiotics results in the weakening of the potencies of the antibiotics relative to the combined (additive effect) potencies of each of the antibiotics.
