Some Biology ?s

these are questions from the online Kaplan free test, but I do not have answers...any help is appreciated!

1. Which of the following illustrates the principle of induction in invertebrates
A. in an embryo, the presenve of a notochord beneath the ectoderm results in the formation of a neural tube
B. A neuron synapses with antoher neuron via a neurotransmitter
C. Eye muscles contrstict in responce to light
D. The maternal parent induces spontaneous expression of recessive genes

I thought the answer was A, but then if you look carefully, the question is asking about INVERTEBRATEs????


2. If two individuals with geneotypes AaBbCc mate, what is the probability that they will produce offspring with geneotype AABBCC?
A. 1/64
B. 1/32
C. 1/16
D. 1/4
E. 1/2
How do you even do this problem?

3. Muscle movement on the cellular level is initated by the release of CA from the terminal cisternae. Terminal cisternae are associated with
a. sarcoplasmic reticulum
B. myosin-cross bridges
C. myoglobin
D. caniliculi
E. Thin filaments

Anyone know the answer? Is this ? too picky?


4. Inbreeding within a population is likely to lead to:
A. an increased number of mutations
B. an increased expression of recessive traits
C. An increased expression of dominant traits
???? They all sound good to me!

5. According to the first law of thermodynamics
A. energy transfer leads to less organization
B. A system that is isolated from any energy source increase in entropy
C. Evolution is possibly through the absorption of energy
D. Energy is balanced by living organisms
E. Total energy in an isolated system remains constant

Is the answer E???


6. According to the second law of thermodynamics
1. matter cannot be destroyed or created
2. conservation of heat to work leads to less organization
3. entropy is unchanged or increases following a thermodynamic process
A. 1 only
B. 2 only
C. 1 and 3
D. 2 and 3
E. 1,2, and 3


Thanks so much!!!
