What causes an ecosystem to move from a primary successional stage towards a relatively-stable mature ecosystem?
Gnoma [55]

Answer:

The correct answer is "secondary succession, an ecological succession step where an area previously occupied by living beings is disrupted".

Explanation:

In ecological succession, an ecosystem changes and develops through a series of steps. The first step, is the primary successional stage where rocks or other sedimentary structures are colonized by microorganisms. The second step, where the ecosystems changes towards a relatively-stable mature stage, occurs when an area previously occupied by living beings is disrupted. This step is named secondary succession, and the most clear example of this phenomena occurs when wildfire clears oak and hickory forests.

PLEASE ANSWER I NEED THE ANSWERS!!!
yKpoI14uk [10]

Answer:

1: 7.8 cm

2: .7 cm

3: 5.55 cm

For the other questions, you have to use a ruler yourself and measure using cm. :)

1 cm = 10 millimeter. To convert, just add a 0 to the end of cm to find the mm (or move the decimal one place to the right.)

For example, 2.6 cm = 26 mm / 5 cm = 50 mm. Hope this helps!

Genes contain instructions for assembling Question 56 options: a. purines. b. nucleosomes. c. proteins. d. pyrimidines.
sergejj [24]

Answer:

c. Proteins

Explanation:

A stretch of DNA that code for specific proteins is said to be a gene. A gene is transcribed into mRNA. The mRNA has a nucleotide sequence complementary to the corresponding gene. The nucleotide sequence of mRNA is read in the form of genetic codes during the process of protein synthesis to specify the amino acid sequence of proteins. Therefore, genes carry the genetic information for the assembly of proteins and the processes of transcription and translation deliver the stored genetic information.

Place the steps of endochondral ossification in order, starting with the creation of a cartilage model and ending with the prese
Ratling [72]

The correct  steps of endochondral ossification is:

  1. A periosteal bone collar develops.
  2. spongy bone and the medullary cavity form in the diaphysis.
  3. The diaphysis center is vascularized and osteoblasts deposit osteoid over calcified cartilage matrix.
  4. The epiphyseal center is vascularized and osteoblasts deposit osteoid over the calcified cartilage matrix.
  5. The spongy bone forms in epiphysis.

<h3>Which bones grow by endochondral ossification?</h3>

Long and short bones, such as the phalanges and femur, arise from a cartilage model formed by endochondral ossification. Distinguishing between these two types of osteogenesis does not imply the existence of multiple types of bone tissue.

Endochondral ossification mainly forms in two stages: modifications of the hyaline cartilage that ends with the death of chondrocytes and invasion of osteogenic cells and their differentiation into osteoblasts in the cavities previously occupied by chondrocytes for deposition.
