unsolved questions from destroyer bio

hey i just went over the bio section and still have some questions

#47. it says ADH increases blood pressure when H2O is reabsorbed.
How does it increase blood pressure???


#102. when it says dihybrid, how do we know it's always heterozygous?
can't AABB or aabb, or AaBB all be dihybrid?
it didn't specify that they are heterozygous dihybrid but it just assumed.


#135. how does passive diffusion and active transport in loop of Henle help in the conservation of water?
And can't we say helper T cell is humoral immunity?

#143. I know that myoglobulin can carry oxygen in muscle but why do we need oxygen in muscle if it's anaerobic process?

#145. It says norepinephrine is the primary neurotransmitter of sympathetic nervous system. According to my human phyisology note, ACH to niconitic receptor happens first and then norepinephrine to adrenergic receptor happens 2nd so shouldn't norepinephrine be secondary neurotransmitter and ACH is the primary instead?

#157. Does octopus belong to mullusk or cephalopoda?

#167. How do we know that blue eyes are homozygous recessive?

#174. what's the point of bastesian mimicry if it doesn't give them any benefits like Mullaian does?

#178. How can egg cell contain 23 chromosomes and 23 chromatids? aren't chromatids always half of chromosomes?

#222. It says ubiquinon is coenzyme Q that carries electron. Isn't cytochrome the electron carrier?

I'm gonna answer what I can.

#47 Higher volume=higher pressure

#102 Dihybrid cross is one of F1 offspring and have to be heterozygous

#135 T-cell are considered cell mediated

#143 Muscle cells also do aerobic respiration

#145 Epinepherine and norepinerpherine are sympathetic, ACH is parasympathetic

#157 Both, one is a phylum the other is a class

#174 Batesian is when a harmless imitates a harmful organism to prevent predation

#178 A chromosome can have one or two chromatid depending on whether its meiosis or mitosis

#222 Ubiquinone is the main electron carrier

You're physiology notes are right. In both nervous systems there are pre-ganglionic and post ganglionic neurons. BOTH use ACh in their preganglionic transmissions, but I think this is too much for the DAT. Just be aware that sympathetic is norepeniphrene and parasympathetic is ACh.

As for batesian mimicry TQS said it right. Mullerian mimicry is when two predatious species look alike, whereas batesian is an adaptation for survival of a non-predatious species. For example, there is some type of beetle which is harmless, but it resembles a wasp and predators know not to eat it.



And usually, black is dominant, but I think it will usually say which is dominant and which is recessive. But in terms of like eyes or hair, black wins out.

Ooops, I ment Mullerian mimicry is useful since they can mimic and survive.
But how does batesian mimicry benefit the species?
Mullerian mimicry is to survive from predator but like pbure9 said,batesian mimicry happen to non-predatious species so I don't think it will increase their chance of survival.

Batesian mimicry is when a species is not dangerous at all but pretends to be dangerous so that predators would leave it alone therefore increasing its survival. Example is viceroy and monarch butterflies.

Mullerian mimicry = predators avoid all guys that look like gangsters
Batesian mimicry = predators avoid a wussy nerd that dresses up like a gangster

#145

Sympathetic:
presynaptic: ACH
postsynaptic: Norepinephrine (except for sweat gland which is ACH)

Parasympathetic:
presynaptic: ACH
postsynaptic: ACH

Dude primary here means 'main' not 'first in order'.

UCB05: lol, love the def

lol at this im pretty sure irl the nerd would get killed anyway.

Do we seriously have to know that much detail. What is the presynaptic NT and what is the postsynaptic NT for each subdivision of the Autonomic NS? And does the DAT actually go into that much detail about mimicry and etc... Ive never even heard of Batesian mimicry? Is this all required? Im freakin out ... wtf

I dont think the post and presynaptic neurotransmitters are imp...too much detail..but if you know its awesome for you.


Mimicry: you need to know that for sure. Batesian and Mullerian are the most basic concepts in mimicry and there is a very high chance of questions on it. But you dont need too much detail, just the ""very cool" definition above in the post about gangsters is great (if you get the idea). 🙂👍
