Decomposers are like the housekeepers of an ecosystem. Without them, dead plants and animals would keep piling up with the nutrients the soil needs trapped inside. Decomposers clean up the dead material by processing it and returning the nutrients to the soil for producers.
-The number of B cells producing the antibody is proportional to the concentration of that antibody.
-On day 16, one out of 100000 B cells are specific for antigen A
\frac{1}{100000} = 1 x 10⁻⁵ B cells
- on day 16, Antibody concentration is 2 × 10¹= 20 Antibodies
- on day 36, antibody concentration 8 × 10³.= 8000
20 antibodies ------------ 1 x 10⁻⁵ B cells
8000 antibodies--------------x
x= (8000 x 1 x 10⁻⁵)/ 20
x= 4x10⁻³ or 1 in 250 are <span>B cells specific for antigen A</span>
Answer:
animals such as bees, squirrels, songbirds, and even humans. Nocturnal animals sleep during the day, and move about at night. These include animals such as moths, bats, frogs, and cats. Artificial light affects both, but in different ways.
The bones that form the prominences of the cheeks as well as part of the lateral wall and floor of each orbit are the Zygomatic bones.
The zygomatic bone is proportionately small but structurally important. It is almost quadrangular in shape and it is characterized by three surfaces, five borders and two processes.
It conveys the pressure exerted on the zygomatic region towards three otherwise unconnected bones i.e. the maxilla, the frontal as well as the temporal bone.
The zygomatic bones also possess the system of canals for the branches of the zygomatic nerve. The zygomatic bone extends backward to join the zygomatic process of the temporal bone, making the zygomatic arch.

Answer:The inward flow of sodium ions increases the concentration of positively charged cations in the cell and causes depolarization, where the potential of the cell is higher than the cell's resting potential.
