Active Immunity is produced inside of the body, whereas passive immunity is introduced from outside of the body.

Active Immunity is from direct infection and vaccination.

Passive Immunity is from Breast milk, Injection, Mother to baby through the placenta.

Active Immunity takes effect over time (typically several weeks).

Passive Immunity takes effect immediately.

Baltes' lifespan perspective that development is lifelong, multidimensional, multidirectional, plastic, contextual, and multidisciplinary.

Many disciplines are capable of make a contribution critical ideas that combine knowledge, which can also additionally in the end bring about the formation of a brand new and enriched expertise of improvement throughout the lifespan.

Baltes is regarding the truth that a complicated interaction of things impact improvement throughout the lifespan, such as biological, cognitive, and socioemotional changes. Baltes argues that a dynamic interplay of those elements is what affects an individual’s improvement.

Dovator [93]

The plasma membrane or the cell membrane is the one that protects the cytoplasm of a cell. It is mostly composed of lipids and proteins. It has a phospholipid bilayer that controls the entering and exiting of molecules in the cell and at the same time, provides protection for the cell or plasma membrane. It has polar head and a nonpolar tail. Proteins embedded within the phospholipid bilayer have the same function of the plasma membrane that includes selective transport. The phospholipid bilayer consists mainly of the lipid molecules.

Summarize the nitrogen cycle and it’s importance of proteins and DNA

iren2701 [21]

Answer:

Nitrogen cycle works through various stages like, nitrogen fixation, nitrification, assimilation, ammonification, denitrification etc. It is a building block for protein and DNA

Explanation:

Nitrogen is an element abundantly found in the atmosphere, also its building block for proteins as well as nucleic acid i.e. DNA formation. In nitrogen cycle , the nitrogen is being prepared from inert nitrogen. The nitrogen cycle has several processes like nitrogen fixation, in this the inert nitrogen is being converted to organic nitrogen with the help of certain micro-organism.

Nitrification, plants cannot absorb directly nitrogen so bacteria help the plants to convert the nitrogen into ammonia form in this stage. Assimilation, another stage in which plants starts absorbing various forms of nitrogen from the soil.i.e. nitrate, nitrite and ammonium. Ammonification, here plants and animals have nitrogen in there body after death various microbes help in decomposition in this stage. Denitrification, in this stage the return back of nitrogen takes place.
