The number of neutrons in each atom
Answer:
Plants capturing light energy to form simple sugars using water and carbon dioxide is called
photosynthesis
Answer:
A. Reduction in soil mass proved that plants get their food from the soil.
Explanation:
Plant take their food from the soil because in soil roots are present which absorb nutrients from the surrounding environment. The nutrients present in the soil comes from the decomposition of dead bodies of plants and animals and sometimes it is provided by the farmers in the form of fertilizers. The plant food contains nitrogen, phosphorus and potassium which is required in large amount for the better growth and development of the plant.
Answer:
the hip bone
Explanation:
The bone marrow is divided into two; yellow and red bone marrow. The yellow bone marrow stores fats and contains mesenchymal stem cells which can develop into muscle cells or cartilage. The yellow marrow is located at the central cavities of long bones while the red bone marrow is located at the hip, sternum and humerus.
For a red bone marrow biopsy and aspiration to be done on a patient, the samples should be best obtained from the hip bone because it is a flat bone with soft tissues and no major organs and blood vessels are located.
Answer:
if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down)
Explanation:
The pressure is the second most principal factor that influences metamorphic rocks. It originates from the weight of the own materials, their densities, and the deepness.
Litostatic pressure originates from the weight of materials in the interior of the crust.
Pressure generates alignment of materials (foliation and schistosity) and mineral rotation.
There are different types of metamorphism.
Dynamic metamorphism is the one where pressure is the principal factor. It generates by tectonic conditions, and it presents mainly in failure or fracture areas. It provokes trituration and recrystallization of minerals.
Classification of the metamorphic rocks according to their structure:
- Granulation
- Recrystallization
- Metasomatism
- Massive
- Foliation
Foliation refers to dynamic metamorphism, where pressures act and minerals orientate perpendicular to the pressure direction.
<em>According to this concept, if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down) while minerals' weight helping in the process of foliation. </em>
