It provides energy for the cell to build, repair, and reproduce. Cells needing more energy have more mitochondria.
Specialization is a method of production whereby an entity focuses on the production of a limited scope of goods to gain a greater degree of efficiency. Many countries, for example, specialize in producing the goods and services that are native to their part of the world, and they trade for other goods and services. This specialization is, therefore, the basis of global trade, as few countries have enough production capacity to be completely self-sustaining.
Answer:
The correct answer will be- Direct signalling
Explanation:
Direct signalling is a type of signalling which takes place between the neighbouring cells through gap junctions present between them.
The cardiac muscle cells possess gap junctions which allow the transmission of signals between cells. The cells of the muscle perform the same function simultaneously as the gap junctions allow the transmission of electrical signals.
Since this direct cell to cell transmission of the cell involves the gap junctions and thus direct signalling is the correct answer.
The transfer of signaling molecules communicates the current state of the cell that is directly next to the target cell; this allows a group of cells to coordinate their response to a signal that only one of them may have received. In plants, plasmodesmata are ubiquitous, making the entire plant into a giant communication network.
Gap junctions are particularly important in cardiac muscle: the signal to contract is passed efficiently through gap junctions, allowing the heart muscle cells to contract in unison.
y transferring signaling molecules across gap junctions between neighboring cells.
Answer:
Carbohydrates, such as sugar and starch, for example, are readily broken down into glucose, the body's principal energy source. Glucose can be used immediately as fuel, or can be sent to the liver and muscles and stored as glycogen.
Answer:
A nominal scale describes a variable with categories that do not have a natural order or ranking. You can code nominal variables with numbers if you want, but the order is arbitrary and any calculations, such as computing a mean, median, or standard deviation, would be meaningless.
A nominal scale is a scale (of measurement) that uses labels to classify cases (measurements) into classes. Some examples of variables that use nominal scales would be religious affiliation, sex, the city where you live, etc. Example. One example of a nominal scale could be "sex".
For example, Race is a nominal variable having a number of categories, but there is no specific way to order from highest to lowest and vice versa.
