nata0808 [166]

Answer:

Outer Core of Earth

Explanation:

The outer layer of core of earth consists of iron as a major constituent. Due to internal high temperature and low pressure (as compared to the inner core) , the iron in this layer exists as liquid iron. Since the earth is rotating continuously on its axis, the liquid iron is also rotating thereby producing magnetic field. Due to magnetic field , this sphere of earth is known as magnetosphere.

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:

A periosteal bone collar develops.
spongy bone and the medullary cavity form in the diaphysis.
The diaphysis center is vascularized and osteoblasts deposit osteoid over calcified cartilage matrix.
The epiphyseal center is vascularized and osteoblasts deposit osteoid over the calcified cartilage matrix.
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.

Categorize the given minerals into metallic and non-metallic minerals?

tangare [24]

Iron, Gold, Aluminum, Sapphires and Copper are the metallic minerals while Quartz, Calcite, Diamond, Rubies, Emerald, Topaz, Coal and Petroleum are the non-metallic minerals.

<h3>What are minerals?</h3>

Mineral is a chemical compound which is normally crystalline in nature. It is a solid substance present in nature made up of one or more and elements which are combined together.

It is formed as a result of geological processes . For example it includes quartz, calcite, sulphur, clay minerals etc. Minerals are used in the production of ceramics oftenly.

Properties of minerals :

1. They have characteristic chemical composition

2. They have highly ordered atomic structures

3. They have several physical properties such as hardness, luster and cleavage.

Thus, Iron, Gold, Aluminum, Sapphires and Copper are the metallic minerals while Quartz, Calcite, Diamond, Rubies, Emerald, Topaz, Coal and Petroleum are the non-metallic minerals.

Inessa [10]

The Mitochondria in many cells, are believed to have been bacteria that have been incorporated in the cytophysiology. Mitochondria first off, contain their own DNA, er, RNA. Additionally physiologically the mitochondrion, has an inner membrane and some organelle traits similar to prokaryotic cells. Lastly Mitochondria are the only organelle capable of replicating itself. <span />

What is the relationship between the pH of pond water and the survival rate of animal species living in the pond

Aloiza [94]

<h2>Answer:</h2>

The pH of the pond water and survival rate of animal species living in the pond has a direct relationship with each other. Animal species can survive at a specific level of pH"Optimum pH" at which these species can show their maximum activity.

If we decrease the pH the pond water will become more acidic and it will become challenging for species to survive in the acidic environment and if we increase the pH the water becomes more alkaline and again it affects the marine life. So, the pH of pond water should be in normal ranges.
