When a neutrophil discharges its enzymes into the tissue fluid?
Alik [6]
Both the macrophages and the neutrophils can discharge their lysosomal enzymes, via exocytosis, into the extracellular fluid or release their entire cell content when the cell ( macrophage or neutrophil) dies. Releasing of these enzymes assists in the digesting of the inflammatory exudate. 
Neutrophils wander in the connective tissue killing bacteria, they produce a cloud of bactericidal chemicals which creates a killing zone. Lysosomes discharge contents into tissue fluids through a process called degranulation, the comes the respiratory burst which is when the neutrophils absorb all the oxygen which causes toxic chemicals to be created.

Which best describes radiometric dating?
DIA [1.3K]

The answer is; B


Rocks have naturally occurring and spontaneously radioactive atoms in them, such as carbon-14. These element isotopes decay into other types of atoms over millions of years. Therefore, by measuring the amount of these radiometric substances, and knowing the half-life of the isotopes, it is possible to postulate the age of a rock to within certain ranges of error.

A normal man and normal woman marry. What is the chance that they will produce a male child with Down's syndrome?
nikitadnepr [17]

Answer:

The chance of a normal couple having a child with down syndrome is 1 to 600 births.

Explanation:

Down syndrome is a genetic flaw that occurs when the fetus is being formed.

A human cell considered normal has 46 chromosomes, divided into 23 pairs. For some unknown reason, an error may occur at the beginning of embryonic development and an extra chromosome is created, which binds to par 21. The result is cells with 47 chromosomes. This causes the said syndrome.

It is important to know that this failure happens at random. It is nobody's responsibility. It has not been proven to date that lifestyle, actions during pregnancy, smoking, drinking, medicines, environmental factors or kinship between the couple can influence this occurrence. She is not contagious either. The likelihood of a normal couple having a child with the syndrome is approximately 1 to 600 births.
