Answer:B cell sub-type that are formed within germinal centers following primary infection. Memory B cells can survive for decades and repeatedly generate an accelerated and robust antibody-mediated immune response in the case of re-infection (also known as a secondary immune response).
Explanation:
Answer:
They release energy as they degrade polymers to monomers.
Explanation:
In a catabolic pathway, complex hydrocarbons are usually broken down to their monomeric units.
This breaking down leads to the release of energy.
- Anabolic pathway leads to the build up of energy. One of such process is photosynthesis.
- The catabolic pathway breaks down compounds to simpler units in order to release energy.
Answer: Meiosis is the necessary process for the inherited traits of an organism to be passed along by sexual reproduction to bring about variation.
Explanation: Meiosis occurs in reproductive cells. It halves the chromosome number of parents to produce same (constant) number of chromosomes in the offsprings.
Meiosis leads to genetic variation among offsprings through recombination, crossing over, independent assortment and reduction and fusion of gametes.
Most abnormalities that are heritable are as a result of improper division during meiosis.
Answer:
The cellular level of an organism is where the metabolic processes occur that keep the organism alive.
Explanation:
Phases or components
Your textbook describes two
sequential phases of interaction between organisms and their environments that
have existed since god's creative work began. Organisms interact with their
environments in different ways. Different organisms of a biological community cooperate
and compete for habitats and share the resources in that habitat.
