Answer: D, to create the soil

Explanation:

Primary succession occurs on basically empty, lifeless land with no soil. Pioneer species are the first plants to colonize the land after primary succession, which means they are very primitive and can survive without soil. Since there is no soil, their role is to create soil for more advanced organisms to survive in the area in the future.

Answer:

to create the soil

Explanation:

Pioneer species refers to the first species that colonize the area and serves as first stage of succession. Pioneer species initiate the soil formation by breakdown of substratum.

Example: Crustose lichens are pioneer species on rock surface. These species carry out rock erosion to initiate soil formation. Addition of dead and decayed lichen to the soil makes it fertile and suitable for growth of other plant species.

Answer:

Through symptoms.

Explanation:

We diagnosed the problem was a kidney failure due to the decreased urine output , swelling in your legs, ankles or feet, shortness of breath, fatigue, confusion, Nausea and Weakness. The main symptom is the swelling in legs, ankles or feet that tells about kidney failure. The treatment goal of Hemodialysis is to filter waste products and water from your blood. I works just like the kidneys. This treatment is used when the kidney fails to filter waste materials inside the body.

Ms. Lasater spent $16.50 on 8 whiteboard

spayn [35]

<u>20 markers will cost Ms. Lasater $41.25.</u>

<h3>Proportion</h3>

This is a topic in mathematics that treats a value as a part of the entire data.

In the question given, we were asked to find the cost of 20 markers.

Data given;

8 markers is sold for $16.50

To solve this problem, we can either find the cost of one markers and multiply the value by 20 to get the cost of 20 or simply set an equation to find the cost of 20 markers.

Let the cost of 20 markers be represented by x

$8 marker = 16.5\\20 markers = x\\$

cross multiply both sides and solve for x

$20 * 16.50 = 8x\\330 = 8x\\8x/8 = 330/8\\x = 41.25$

20 markers will cost $41.25

From the calculation above, we have the follow data

8 markers costs $16.50
20 markers cost $41.25

If antibodies to fibronectin are exposed to an embryo through which neural crest cells are migrating

lidiya [134]

Answer:

Neural crest cell movements are inhibited.

Explanation:

Neural crest cells may be defined as the temporary group of cells that are unique for the chordata group. These cells arise from the embryonic ectoderm and give rise to future melanocytes.

Antibodies to fibronectin association is helpful to study the signalling factors. If these anitodies to fibronectin is shown in the embryonical stage. The neural crest migration is inhibited by its exposure to fibronectin and this might hinder the embryonic development.

Thus, the answer is neural crest cell movements are inhibited.

Georgia [21]

The pressure in the glomerulus that tends to favour filtration is known as the glomerular capillary pressure.
<span>
Glomerular capillary pressure is the main force in producing glomerular filtration and it is a fluid pressure exerted by blood within glomerular capillaries. It depends on hear contraction and resistance to blood flow by afferent and efferent arterioles in the kidney.</span>
