Answer and Explanation:
The femoral biceps is one of the hamstrings. These muscles are located in the back of the thigh and are the most important knee flexors.
In addition, the biceps have the ability to extend the thigh over the pelvis and rotate the hip laterally. This is because it has a muscular belly that originates from the hip, more precisely in the ischial tuberosity of the ischium.
When the biceps are contracted, its most important function is to contract the knee, but if it remains rigid its function will be mainly the extension of the thigh.
Answer:
B.) Gap junction
Explanation:
Plasmodesmata (singular form: plasmodesma) are intercellular organelles found only in plant and algal cells. (The animal cell "equivalent" is called the gap junction.)
All the soils are made up of water, organic matter, air, and the mineral particles, but the combinations of all these elements determine the soil’s texture, colour, and porosity. This will help the people to identify the fertility soil.
Explanation:
- Soil’s structure referred to the size of the particle which made the soil. Soil texture is very helpful to understand whether the soil is free from draining, how easy to grow plants and how much soil can hold water.
- Soil’s porosity means the pores which are present in the soil. Pores are very helpful for the movement of water and air through the soil. Healthy soil will have many pores in them.
- The colour of the soil can vary from black to red to white. The source of the soil colour is from iron and organic matter. The topsoil will be dark due to the presence of organic matter. The single colour indicates that the soil is very drained.
The Cryosphere is consisted of earths frozen water. The Geosphere and the Cryosphere interact by ice-wedging, and weathering rocks.
