What are the main roles the endocrine system plays within the body?

contained in chromosomes, which are in the cell nucleus.
develop into many different types of cells in the body.
central region of the human brain formed by nervous fibers and a conglomerate of nuclear bodies with various functions.
Does the hypothalmus interact with the pituitary gland?
Yes, Its function is to secrete releasing hormones and inhibiting hormones that stimulate or inhibit (like their names imply) production of hormones in the anterior pituitary.
No, Its function does not secrete releasing hormones and inhibiting hormones that stimulate or inhibit (like their names imply) production of hormones in the anterior pituitary.
How does the endocrine system release hormones into the body?
Genes are contained in chromosomes, which are in the cell nucleus.
This lets the hormones travel to cells in other parts of the body.
What are the causes of genetic disorders?
by a combination of gene mutations and environmental factors, or by damage to chromosomes (changes in the number or structure of entire chromosomes,
material to be maintained and generations to be linked.
potential to develop into many different types of cells in the body.
What are genes?
? Organisms produce other similar organisms through sexual reproduction
connected to will be expressed in an individual.

characteristic it is connected to will be expressed in an individual.
they aren't related
How is genetic information passed from one generation to the next?
They can't pass from one generation to the next
connected to will be expressed in an individual.
Organisms produce other similar organisms through sexual reproduction, which allows the line of genetic material to be maintained and generations to be linked.

Explain the difference between dominant and recessive traits
a parent with a dominant phenotype but unknown genotype is crossed with a recessive parent.
Recessive alleles only show their effect if the individual has two copies of the allele (also known as being homozygous?
dominant, the characteristic it is connected to will be expressed in an individual. When an allele is recessive, the characteristic it is connected to is less likely to be expressed.
What are stem cells?
