<em>Examples of a nonspecific external response to infectious agents and harmful bacteria are the following;</em>
Mucus, saliva, and tears.
They are nonspecific external responses that help to prevent pathogens from entering our bodies.
The specifics contain types of enzymes that break down the bacterial cell walls. An external response of Mucus tends to trap pathogens as well.
Answer:
1. They have to be able to reproduce, either asexually or sexually.
2. They have to be able to respond to stimuli.
3. They have to have cells, either as a unicellular organism or as a multicellular organism.
4. They have to grow and develop.
5. They have to have homeostasis. This means that they can maintain their own body temperature. Think of this as a thermometer for the body.
6. The last thing is that all living things also have to be able to do is move.
Explanation:
<span>At the end of prophase , nuclear membrane , nucleolus and all the cell organelles disappears and there is no distinction between the nucleoplasm and cytoplasm</span>
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. During reproduction, when the sperm and egg unit to form single cell for sexual reproduction. During reproduction, when the sperm and egg unit to form a single cell, the number of chromosome is restored in the offspring.
Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome. The parent cell undergoes one round of DNA replication followed by two separate cycles of nuclear division. The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.
The answer is D because they speard apart or interact in all boundaries.
