A student creates the table above as a study guide. evaluate the accuracy of the information shown. the information is not accur

ate because the anterior air sacs push air when they expand and pull air when then contract. the information is not accurate because air sacs expand during exhalation and contract during inhalation. the information shown is accurate. the information is not accurate because air does not flow through the lungs during exhalation.

Attached is the mentioned above table. I found the exercise on the internet.

The correct answer is:
"<span>the information shown is accurate."
When birds breath in, their posterior air sacs inflate with air from the outside, and their anterior air sacs inflate with air from the lungs. When they breath out the air that was then in the posterior air sacs is now pushed to the lungs, and the air that was in the anterior air sacs is expelled through the trachea.</span>

noname [10]

Answer:

"C" is the answer, Myosin would be able to bind to bind to the exposed binding sites on thin filaments but would not be able to detach

Explanation:

ATP is required for muscle contractions. muscle fatigue results in the decline of muscle force generated over time during metabolic fatigue there is depletion of required substrate such as ATP or glycogen as muscle is not able to generate energy to power contractions. accumulation of metabolites from this reaction other than lactic acid or reactive oxygen species can also induce fatigue by interfering with the release of Ca++ from the sarcoplasmic recticulum.

European rabbits were introduced into Australia and quickly spread, reproduced, and became a terrible pest. They eat up to $600
Alina [70]

Answer:

True. This is the case where an invasive species has reduced the genetic diversity of indigenous species.

Explanation:

  • An invasive species is an exotic, foreign species that takes over a specific habitat or ecosystem and destabilizes it.
  • Invasive species disrupt the food chains of an ecosystem which may lead to increase in populations of some species while reducing others.
  • Invasive species compete with indigenous species for food, shelter and mates. As the indigenous species cannot reproduce properly, a reduction in their genetic diversity is the direct result.

Calcule la molalidad de una<br> 20g Ca Cl₂ en 250g de<br> que contiene<br> solucion<br> H₂O.
ahrayia [7]

Answer:

The solution is 0, 90 molal. See the explanation below, please

Explanation:

Molality is defined as moles of solute in 1 kg of solvent (1000 grams). The following three simple rule must be performed:

We calculate the weight of 1 mol of CaCl2

Weight Ca =40, 078 g

Weight Cl= 35, 453 g

Weight of 1 mol of CaCl2=40, 078g + 2x (35, 453g )= 110, 98g

110, 98 g ---1 mol

25 g---X= (25g x1 mol)/110, 98g= 0,23mol

250g solvent -----0,23 mol CaCl2 (the solute)

1000g solvent ----X = (1000g x0,23mol)/250g =0,90 mol solute

The solution is 0,90 molal

Which of these correctly shows ecological succession in a lava field?
larisa [96]

The ecological succession that occurs in a lava field is as follows:

  • Moss and lichen arrive by birds to barren lava field.
  • Soil is created.
  • Fountain grass grows.
  • Monkeypod trees grow.

<h3>What is ecological succession?</h3>

Ecological succession refers to the series of changes that occur in a habitat gradually with new species replacing existing species or a barren habitat until the environment becomes more complex.

A lava field is a barren field where there are no species

The ecological succession that occurs in a lava field is as follows:

Moss and lichen arrive by birds to barren lava field; Soil is created; Fountain grass grows; Monkeypod trees grow.
