Resting potential (in mV)

-70 mV I 5a

I 10 Name of three physiological responses to signals sent through sympathetic nerves

I 10a Increased heart rate, Dilation of airways Increased breathing rate Decreased digestion Release of adrenalin from adrenals

I 15 Explain the relative levels of Na+ and K+ across the membrane of a neuron at rest.

Higher Na+ outside of cell and higher K+ inside of cell I 15a

Sodium and potassium gates are located at these places along an axon

I 20a Nodes of Ranvier

I 25 Entry of this ion causes exocytosis of vesicles containing neurotransmitters

Ca2+ I 25a

II 5 This part of the brain secretes many hormones and controls the pituitary gland

II 5a

This part of the brain is responsible for “muscle memory” II 10 This part of the brain is responsible for “muscle memory”

II 10a

Part of the brain that regulates breathing and heart rate II 15 Part of the brain that regulates breathing and heart rate

II 15a

Part of the brain the plans and controls movement of voluntary muscle II 20 Part of the brain the plans and controls movement of voluntary muscle

Motor cortex II 20a

Damage to this area of the brain results in a language disorder which results in fluent but meaningless speech. II 25

II 25a Wernicke’s Area

III 5 This germ layer gives rise to skin, hair, central nervous system

Ectoderm III 5a

Name of the process during which the three germ layers are established III 10 Name of the process during which the three germ layers are established

Gastrulation III 10a

III 15 The cortical reaction results in the formation of a _____ which prevents a second fertilization.

A fertilization envelope III 15a

The name of these structures: III 20 The name of these structures:

III 20a Neural plate Notochord Archenteron

III 25 The ___ of the frog and the ___ of the chick are the sites of involution during gastrulation

Dorsal lip; primitive streak III 25a Dorsal lip; primitive streak

IV 5 The process by which signals sent from some cells affect the developmental fate of other cells

Induction IV 5a

These genes determine segment identity IV 10 These genes determine segment identity

IV 10a Homeotic genes (HOX)

IV 15 Name of two genes that determine the anterior-posterior axis in the fruit fly

Bicoid, hunchback, or nanos IV 15a Bicoid, hunchback, or nanos

IV 20 When bound to a TOLL receptor, SPZ triggers the activation of this transcription factor which determines the ________ axis formation.

IV 20a DL; dorsal-ventral

IV 25 Describe the gradient of Hunchback mRNA and Hunchback proteins in the fruit fly embryo.

HB mRNA is evenly distributed and HB protein is concentrated at the anterior end. IV 25a

How many days following conception does the human primitive streak form? About 24 hours 3-4 days 13-14 days About 3 weeks V 5

c. 13-14 days 13 or 14 days after conception: A "primitive streak" appears. It will later develop into the fetus' central nervous system. This is the point at which spontaneous division of the blastocyst -- an event that sometimes generates identical twins -- is not longer possible. The pre-embryo is now referred to as an embryo. It is a very small blob of undifferentiated tissue at this stage of development. V 5a

Name the order that includes beetles V 10 Name the order that includes beetles

Coleoptera V 10a

V 15 What is this? A newt larva An egg of a sponge being fertilized A jellyfish eye None of the above

c. The eye of a box jellyfish V 15a c. The eye of a box jellyfish

How many cells does the adult male C. elegans have? 1031 997 1142 1320

V 20a 1031 The developmental fate of every single somatic cell (959 in the adult hermaphrodite; 1031 in the adult male) has been mapped out. In both sexes, a large number of additional cells are eliminated by programmed cell death (apoptosis).

What is Gilderoy Lockhart’s favorite color?

V 25a Lilac
