Answer:

d. hematoma formation, soft callus formation, bony callus formation, and bone remodeling

Explanation:

All body tissues have the ability to regenerate against injury, replacing damaged tissues with new tissues that must have the same shape and characteristics of healthy tissue. Bone is a tissue that despite its hardness has an important regeneration capacity and a certain time for repair. The bone repair process after a fracture is also called bone consolidation. In this text the different bone repair processes will be described when a fracture occurs and what happens when this process is delayed.

Bone consolidation occurs in 4 phases that follow one another. These are: inflammatory, proliferative, fracture callus formation and remodeling.

<u>Inflammatory and proliferative phase </u>

When a bone suffers an impact, it absorbs the energy released along with the surrounding soft tissues. If the amount of energy does not exceed the absorption capacity of bone forces nothing happens, but if this energy is excessive it will not be absorbed and the fracture will occur; which implies a local hemorrhage and necrosis of both bone and soft tissue cells, which surround the fracture area.

<u>Fracture callus formation </u>

Between the second and third week the soft fracture callus begins to form. During this phase the cells proliferate in the periosteum (outermost layer of bone), in soft tissues and in all surrounding vascularized tissue; and they begin to differentiate into osteoblasts (cells that will form the new bone tissue), osteoclasts (cells that reabsorb and reshape the bone) and chondroblasts (cells that create cartilage tissues).

Periosteum cells proliferate rapidly, seeking the union of fracture fragments. Therefore, a periodic sleeve is formed that wraps around the soft callus. At this time the fracture can be manipulated without noticing crepitus, since the bone fragments do not move.

<u>Remodeling phase </u>

The consolidation process ends with an adaptive remodeling, which can last for months or even years.

Various factors are involved in this consolidation process: cellular, vascularization, organism's biochemicals (hormones, vitamins), local biochemical factors (growth factors) and biophysical (mechanical) factors

artcher [175]
<h2>Himalayas </h2>

Explanation:

  • Once, all the world’s landmass was connected, forming one super-continent known as Pangea
  • About 200 million years ago, tectonic forces broke apart this giant continent into pieces, eventually forming the continents that are known today
  • As convection currents worked independently on the plates associated with these new continental pieces, the plates and their respective continents began to drift across the globe to their present-day geographical locations
  • Eighty million years ago, India was approximately 6400 km south of the Eurasian plate, separating the two was the Tethys Sea
  • The Indo-Australian tectonic plate – containing the continent of Australia, the Indian subcontinent, and surrounding ocean – was pushed northward by the convection currents generated in the inner mantle
  • For millions of years, India made its way across the sea toward the Eurasian plate
  • As India approached Asia, around 40 million years ago, the Tethys Sea began to shrink and its seabed slowly pushed upwards
  • The Tethys Sea disappeared completely around 20 million years ago and sediments rising from its seabed formed a mountain range
  • When India and Tibet collided, instead of descending with the plate, the relatively light sedimentary and metamorphic rock that makes up the subcontinent of India pushed against Tibet, forcing it upwards, and created a massive mountain fold, The Himalayas
  • This process hasn’t stopped, the Indo-Australian plate is still moving toward Eurasia, still pushing Tibet upwards
  • The Himalayas continue to rise by an average of 2 cm each year and the highest mountains are only getting higher

How is it possible that all animal life depends on the chloroplast for energy
Deffense [45]

chloroplast contains chlorphyll . Chlorophyll is used in photosynthesis to produce glucose . (photosynthesis is a process where green plants manufacture simple sugar (glucose) from carbondioxide and water by using sunlight ) 6co2+6h2o=c6h12o6+6o2

if theres no chloroplast no glucose will be produced so animals will have no energy. chloroplast must be present in order of photosynthesis to take place and produce glucose , when plants produce glucose animals get the energy needed by feeding on plants (in simple words animals eat the sugar that plants have produced )

The ph of your stomach must be (a)more than 7 (b)basic (c)equal to 7 (d) none of the above
marysya [2.9K]

Answer:

(d) None of the above

Explanation:

The pH of your stomach must be highly acidic, because the optimum pH for pepsin, the chief stomach enzyme, is 1.5.

(a) and (b) are wrong, because both conditions are basic.

(c) is wrong, because pH 7 is neutral.

Multiple Allele So far we have studied traits or genes that are coded for by just two alleles. Like in rabbits, there was one al
Vesnalui [34]

Answer:

The correct answer is BB genotype and BO genotype.

Explanation:

The human blood system or ABO system shows codominance due to the multiple alleles. That means three different alleles for human blood type are present are IA, IB, and i. For easy understanding can be stated as A (for IA), B (for IB), and O (for i).

If someone has blood type B could have a genotype of either BB or BO because of the dominance of B allele on O where is If A allele present with B allele it would show co-dominance.

Thus, the correct answer is the BB genotype and BO genotype.
