prisoha [69]
<h2>False </h2>

Explanation:

The immune system develops integrated innate and adaptive modules that are pathogen type-specific and no single response can effectively control all types of pathogens

Both innate and adaptive immune system operate in cooperative and interdependent ways

Innate immune system is present since birth in an organism and is non specific in nature which means acts against all foreign antigens and molecules and provides first line of defense against pathogens

Adaptive immunity system is the acquired one which is capable of recognizing and selectively eliminating specific foreign antigens and is antigen specific which means can discriminate among different antigens; also has the ability to respond to various kinds of epitopes of pathogens

How is dna copied in your own words?
lianna [129]

Answer:

Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell. To accomplish this, each strand of existing DNA acts as a template for replication.

Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. Several enzymes and proteins then work together to prepare, or prime, the strands for duplication. Finally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands. The following description of this three-stage process applies generally to all cells, but specific variations within the process may occur depending on organism and cell type.

KIM [24]

Answer:

Fewer Offspring than the environment can support

Explanation:

It takes time for  a creature to adapt to its  Environment. So that puts off 2.

Your guaranteed to get traits from your parents so that rules out #1

There isn't really an equal probability of survival for an offspring, ruling out #3.

So that leaves us with 4. I'm not biology expert, I'm just letting you know how I did this problem.  Just in case i'm wrong, I would double check with other answers :)
