3
The adrenal glands, regulated by ________,
release hormones in response to ________. What 5 physiological changes occur? What response are these changes known as?
|
3The adrenal glands, regulated by the nervous system, release hormones in response to dangerous or stressful situations that increase blood pressure, raise heart rate, respiratory rate and metabolic rate, and increase blood glucose levels (the “fight or flight response”).

8What is the scientific name for and tell me the difference between a complete and an incomplete metamorphous? Give me an example of an insect
|
Complete - Holometabolous - The baby looks nothing like the adult. The tissues actually rearrange themselves to make the adult- catapillar
Incomplete - Hemimetabolous - Baby resembles adult. Each stage of metamorphis involves shedding to get to next step- Cockroach |
|
9What three hormones regulate insect development? give the type of hormone too. Also tell me what they do
|
Insect development is regulated by
1. a peptide hormone (PTTH) released from neurosecretory cells in the brain,
that functions as a tropic hormone
2. a steroid (ecdysone) released from an endocrine gland (prothoracic gland)
3. a small molecule (juvenile hormone) released from
another endocrine organ (the corpus allatum).

9Describe the whole process (draw) of the regulation of insect development.

Define Meiosis and what are its two major functions? |
•Meiosis is a replication of the DNA followed
by two rounds of cell division. It has two major functions:
–Creation
“haploid” gametes (sperm and eggs)
–Recombination
of genes by exchange of genetic material between homologous chromosomes
|
|
11
What are Haploid, Diploids and Polyploid?What kind of organisms tend to have polypoids?What exactly is replicated during cell division?What are homologous genes and where are they found? |
1n - 1 set of chromatids or genes, 2n - 2 sets of chromatids or gene, Xn - many set of chromatids or gene
Plants Sister Chromatids Genes that express their phenotypes with similar function. Each chromatid has her homologous gene located on the same position on her sister chromatid. |
