<span>A drumlin differs from a roche moutonnee, in that it is a depositional smooth val shaped small hill up to 1.5 km long and 60 mm tall, having a steep end and a sloping end (elongated in the direction ice flowed). Roche Moutonee is an erosional landform formed when a glacier moving over the top of the rock moves one side giving it a jagged edge and abrading the other side giving it a smooth edge.</span>
Hypertrophy can be defined as the condition in which the size of the cells increases. As a result of increase in the cell size the corresponding size of the tissue and the organ also increase simultaneously. Here, no increase in cell number occurs.
The increase in cell size is caused by the activation or expression of genes producing proteins responsible for the purpose.
Hypertrophy can be categorized into two types which are as follows:
Physiological Hypertrophy.
Pathological Hypertrophy.
In physiological hypertrophy, the size of the cells increases as a result of growth and development. The process happens sequentially and is regulated spatially and temporally. The growth in cell size and hence the organ comprised of the cells is accompanied by the subsequent growth in all the other structures associated with the organ. An example is the growth in the size of the heart as a child grows into an adult.
In pathological hypertrophy, there is an unregulated, uncontrolled and spontaneous activation of genes producing proteins responsible for causing cell size increase. The increase in cell size cause the subsequent increase in the the size of the organs comprising of the cells but as the process is unregulated no subsequent increase in size of the supportive structures is observed. An example is hypertrophic cardiomyopathy in which the walls of the heart thickens due to growth in size of the cells. This restricts blood flow and causes hypertension.
Answer white blood cells are immune system cells that protect the body against disease and foreign invaders they’re generally the largest cell types found in the blood
The blood collection centers eventually refuse to take her blood because the frequency with which she gave blood had left her anemic. Anemia is a condition that develops when your blood lacks enough healthy red blood cells or hemoglobin. <span>Therefore her heart must pump more blood to compensate for the lack of oxygen in the blood. The consequences are huge, leading to an enlarged heart or heart failure.</span>
