Myofibrils are the building blocks or contractile unit of each muscle fiber. The tiniest functional unit of skeletal muscle, the sarcomere, is found in the myofibrils and is made up of protein filaments: actin (thin) and myosin (thick).
Roughly, the definition of 'genotype' is a description of genetic characteristics or makeup. Phenotype can be described as the resulting physical characteristics subsequent to genotype. This means that differences in genetic makeup could greatly influence how something, such as an embryo, develops.
Comment: I use a memory aid for this ind of thing, as I easily get them mixed up. Simply use the two letters of each word. Genotype --> genetic, and phenotype--> physical. Hope I answered your question.
Answer:
B. Don't let the energy into the fridge.
Explanation:
Temperature is actually "heat density." It is proved that warm air contains more heat per gram than cold air. When we open the door, and hot air gets mixed up, we increase the heat density in the refrigerator and decrease it in the room.
Radiation is also a small effect at room temperature. It can glow in the infrared. When warm and cold air is side by side or mixed up, they are dipped in each other's radiation.
Warm air has more heat and therefore glows brighter while cold air gains energy and warms up. It loses more power from radiation and cools. So, if we want to keep our fridge cold, we have to avoid letting heat into the refrigerator.
to find the difference you need to determine which one is affected by the other one, and the one affected id the dependent variable and the other one should be the independent
