There is a U-shaped relationship between memory performance and stress hormones
FALSE
On the contrary - the relationship has the shape of an inverted U (with increasing hormone levels, memory performance first goes up, then goes down, not the other way around)
TRUE OR FALSE
Corticosteroids improve memory (up to a certain extent)
TRUE
Indeed, they have been found to have similar effects to adrenaline
TRUE OR FALSE
An adrenaline antagonist mimics the effects of adrenaline on the nervous system
FALSE
on the contrary, it prevents adrenaline from having its usual effect
TRUE OR FALSE
The adrenal cortex responds to hormonal signals from the pituitary gland
TRUE
TRUE OR FALSE
The adrenal medulla responds to neural signals from the hypothalamus
TRUE
TRUE OR FALSE
The hypothalamus releases hormones
TRUE
It produces both neural signals and hormones - quite an unusual skill set!
TRUE OR FALSE
A "gonadotropin" is a hormone that stimulates the gonads (e.g., causes them to mature, to release hormones)
TRUE
a "tropin" is a hormone that stimulates or activates it's target structure - a gonadotropin causes the gonads o mature, an adrenocorticotropin activates the adrenal cortex, etc.
TRUE OR FALSE
Luteinizing Hormone is a gonadotropin that affects the ovaries
TRUE
LH and FSH are not sex specific - they both stimulate ovaries as well as testes
TRUE OR FALSE
Luteinizing Hormone is a gonadotropin that affects the testes
TRUE
LH and FSH are not sex specific - they both stimulate ovaries as well as testes
TRUE OR FALSE
Primates are bisexual (INHERENTLY, NOT JUST CAN HAVE THE POSSIBLILITY TO BE BISEXUAL)
FALSE
Of course homosexual behaviour in all primate species (at least I've not heard of one where that isn't the case), often in individuals who also engage in heterosexual behaviour. Hence, it seems safe to say that all primate species have the capacity for bisexuality and have bisexual individuals (i.e., individuals who regularly engage in both homo- and heterosexual activities)
TRUE OR FALSE
Bonobos are bisexual
TRUE
For bonobos, however, bisexuality is the norm: virtually every member of the species regularly engages in both homo- and heterosexual behaviour. Hence in this sense, bonobos (as a species) are bisexual, other primate species are not (even though they do have bisexual individuals).In other words, in this generic form, the statement is true for bonobos, but false for primates in general.
TRUE OR FALSE
Prolonged stress can keep the gonads in an 'immature' (not hormone-secreting) stage of development
TRUE
In order to provide an evolutionary benefit, a feature (i.e., a structure or behaviour) must...Select one or more:
increase the organism’s chances to reproduce successfully
increase the organism’s life-span
decrease the likelihood that the organism falls prey to predators
increase the chances of the organism’s offspring to reproduce successfully
increase the life-span of the organism’s offspring
increase the organism’s chances to reproduce successfully
increase the chances of the organism’s offspring to reproduce successfully
In order to be heritable (genetically passed down the generations), a feature (i.e., a structure or behaviour) must...
Select one or more:
increase the individual’s reproductive success
increase the species’ reproductive success
not significantly decrease the individual’s reproductive success
be beneficial to both the parent and the offspring
none of the above
None of the above

Which of the following statements is/are true?Select one or more:

Q9 Graph and long answer option question
Y
ou ran several experiments to study the effect of sympathetic arousal on memory, but unfortunately, you lost your lab book, so you no longer know which data set came out of which experiment. Here are data from one of the experiments:
Which of the following would be true for a rat with complete androgen insensitivity disorder (AID)?Select one or more:
An XX individual would show female-typical sexual behaviour
An XX individual would show male-typical sexual behaviour
An XY individual would show female-typical sexual behaviour
An XY individual would show male-typical sexual behaviour
Neither XX nor XY individuals would show any sexual behaviour
An XX individual would show female-typical sexual behaviour
