Biology seems to have equal gender representation as compared to other sciences. However, I noticed that marine biology has a preponderance of women. I first noticed that most marine biologist names are female, and then I made a better search about it. How did this come about? The sea is considered adangerous place, and supposedly according to the stereotypes women shouldn’t prefer it. Also, I noticed that freshwater biology has a more even distribution, just like most fields. Only marine biology seems to be an outlier.

i have a BSc in biology from a reputable university and did summer research at an ivy league. i heard that as a labtech at the university of arizona i'd be making 25k/year. that doesn't sound like much -- i did a very quick google search learned that the 10th percentile salary for labtechs is around 35k. i didn't search specifically within my field, i'd guess that engineers probably get more, sure...and i get that it's a university...but it still seems pretty low. does anyone here know how i could negotiate this?

Re: male and female lions, who is "in charge" of the pride? I recall school/textbooks would say that while the females did all the hunting, the male ate first and defended the pride from other males and was the one "in charge" of the pride. Now that I reflect on this, I'm questioning it... I've seen some documentaries that seem to show females helping males defend the pride from other males so it would appear that the male is more a symbolic leader of the pride and needs to have the females backing/accepting him to stay in place. Also, it could be that when males challenge/disputes with other males, they are doing so to show the females they are fit and worthy to breed with and continue their genes.

I guess overall I'm just curious if any lion experts would agree that the females are the ones "in charge" of the pride and males are more symbolic.

I appreciate any info!

I don't need a specialist level textbooks, I'm actually preparing for post graduate studies in oral and maxillofacial pathology but I really need to start it from the very start. Thanks in advance

Is the reason that water leaves the descending loop caused by the activities of the ascending loop, and not because of what happens in the PCT? So the osmotic gradient is caused by Na and Cl leaving the ascending loop, and not because the osmotic gradient outside the descending loop was already higher because of substances leaving the PCT, causing water to also leave the PCT, but the water still contines to leave in the descending tube? Or is it only leaving the descending loop because the ascending loop has made the osmotic gradient outside the descending loop higher? This makes no sense tho, becaus the ascending loop comes AFTER the descendig, so how can it affect its activity?????

Yeah, so my science exam took place yesterday and it was of 40 marks. I scored 39/40, and lost a mark in the question that asked, "What is the most abundant gas in inhaled air?". I had marked Nitrogen, however my teacher keep saying oxygen. Mind you, Our textbook says that inhaled air has about 21% oxygen and my teacher agree with that. However, when i asked them what the other 79 (actually 78.8)% is, they refuse to answer that. I only have 2 days to convince her, please tell me how do I convince her.

I've been always wondering why those super cool Portuguese Man O Wars are considered as colonies rather than I dividuals. It is always said that this animal consists of individual polyps building a colony. But how are those polyps considered individual when they all grow from the same structure of the animal and are not self sufficient? Some of them build the tentacles, some the gas-bubble, some the "stomach" structure...

I really can't see how people consider the man o wars as a colony of individual organisms.

Why does it get too popular around everyone? what it does? does it affect badly on your health? i’m craving for answers

I don't know if this is common but whenever I take 50 mg fluoxetine and I don't drink water it hurts my stomach a lot. I think it might be clogging something up or it might just be reacting with the cells

I am arborist and I want to learn more about the evolution of trees; the more scientific the source, the better! Please recommend any books you may know.

Hi I am an engineering student but recently i was really interested in abiogenesis and one of the concept that i saw a lot was that life started with organic molecules that replicated themselves without any "consciousness". As i understand the theory simple molecules like methane,co2,n2 with help of a solvent(water),energy from geological activities(or other sources) and metal catalyst created bunch of complex organic material that increased the chance of a organic material to be produced that can replicate itself in the solution which was abundant in organic matter.

I immediately thought of prions. Their existence is possible by a mechanism for creating proteins failing and they have the ability replicate without any consciousness using the organic material(other protein) in the solution(combined extremly rare). Can it be said prios are a pre-life matter that could possibly turn to life given enough time for evolution.

Also for viruses it seems to be coming from stray dna and rna that found ideal ability to replicate does that mean it is the result of secondary abiogenesis?

Hello! I am in a course equivalent to a bio 101 course in college. I don't know how to approach this phylogenetic tree. I have all my data tables, please help!! Thank you!!

It's easy to see how similar we are to chimps... and also how different we are. It's often said we share 98% of the DNA with them, so... (title)

Not a super serious question, just something that popped into my head. I was looking at horseshoe crabs, and I saw that their blood was blue. Apparently this is because the transport protein in their blood has copper as a central component as opposed to iron, like mammals. My question is, what other metals could function in this way? What other metals could be the base of blood (usually oxygen) transport proteins? And, if any others are possible, what color would the blood be?

The so called midlife crisis is as far as I can see someone who’s suddenly undertaking things out of perceived character, what’s happening in their brain?

My mom is a biology and physics nerd and i am looking for cute Christmas gifts for her!

Would you rather learn how any drug (your choice of drug) affects the human body or learn how any drug (your choice) affects animals

No marine biology I love aquatic life, water in general (Aquarius from Florida what can I say, I like it)

but I think I'll stick to land

I spend a lot of time finding interesting geographical locations on Google maps

I love cycling, cross country riding be it hundreds of miles or thousands,

is there jobs for exploration like this? a bit of my wishlist in life was to travel different countries on bicycles,

I believe our perception of beauty especially towards each other's physical appearance depends on our optical anatomy.

Maybe some eyeballs are too elongated which distorts their visual perception, maybe others have slight variations on their lenses which affects how light travels within the eye, maybe some have too bulge on their cornea.

All of this slight variation hugely affects how we perceived other people as beautiful. If you find yourself ugly when you look in the mirror, don't worry, there's one or more person who will find you as an apple of their eye.

I recently obtained an associates degree in biology, and am now thinking of what to obtain next. I live in houston, so Im not too pessimistic about job prospects with a general biology degree. However, does anyone think theres a better subject to get a bachelors in, such as biochemistry or biotechnology? Thank you

Hello there, sorry if what I'm about to write doesn't make sense.

If we put, let's say, a population of rats, in a completely isolated ecosystem in which environmental conditions never change and give them infinite amount of time to evolve, would they become perfect (or the closest thing to perfection possible) for those conditions? In an infinite amount of time, infinite number of mutations would occur, infinite beneficial ones, and infinite bad ones, The ones that give a disadvantage would get discarded through natural selection, while the beneficial ones would stay. At one point in time, the rats would stop evolving because they would reach perfection.

I was just wondering if something like this could work in theory.

I’m in medical school and I have always been fascinated with how cancers behave. I want to know for example if skin cancers manifest lesions that are region specific to the body. Any input would be greatly appreciated. Thanks

Why have humans not been able to create a real life Super Soldier Serum from the MCU?

What challenges do we face in real life when trying to create a serum that would alter physical fitness properties and durability?

For example an injection would increase the individual’s VO2 max, force production, lactic acid clearance, power, etc to theoretical elite or even inhuman standards that can be attained from just training

I am seriously wondering what is preventing us from creating such a thing. Will we ever be able to create it?
