1. The strength of magnetic field at A is 64 unit, then the magnetic field strength at B. is 256 units.
64 × 64 = 256 units.
2. If the strength of magnetic field B is 6 units then the strength magnetic field at A is 24 units.
which is 256 : 4 = 16 units.
Magnetic field is one of the two ways where the intensity of magnetic field is being expressed.
Demonstrative pronoun is the answer.
Answer:
the average percentage of energy lost as heat
Explanation:
An energy pyramid (also called trophic pyramid) is a graphical representation that exhibits how energy flows at each trophic level in a particular ecosystem. In an energy pyramid, it is possible to determine how much energy is available at each trophic level and how energy flows from producers (e.g., photosynthetic plants) to primary consumers (e.g., herbivores), then from primary consumers to the next trophic level (e.g., carnivores), and so successively to all major trophic groups (e.g., higher carnivores). During this chain, energy is lost as heat when it is transferred to the next level, and the average percentage of energy lost increases at each trophic level, thereby less and less energy is available to major trophic groups.
Answer: B) proteins in the membrane act like gates to control entrance and exit of molecules.
Explanation: Plasma membrane is composed of phospholipids bilayer in which the hydrophobic regions of the phospholipids face each other to form the core of the bilayer. Proteins are embedded in the bilayer through an interaction between the amino acid side chains and the nonpolar acyl chains of the phospholipids. The embedded membrane proteins form channels for passage of ions and other molecules. Each membrane protein is selected for one or more ions or molecules that passes through it. The membrane is said to be semipermeable because it allows the passage of some molecules and excludes the passage of others.
<h2>Least desirable method for processing the crime scene</h2>
You are at a crime scene, collecting glass evidence. Following are the least desirable methods for processing the crime scene for glass fragments as: At a crime scene, a person should be very concerned at the gathering and organization of mirror pieces.
- Proper accumulation and protection methods should be utilized for getting a specimen from glass pieces.
- Put on latex gloves.
- Use clean forceps.
The data should be typed accurately.
