Regardless of how biologically probable it would actually be for a shark to have them, what would their vocalizations probably sound like if they had them, in terms of their shape, the organs in their body that sound waves might bounce off of, etc.?

Its very confusing the way its being reported.

I think it's just an encapsulating term that suggests a landscape of ecological terrorism, and the domination of resources.

You then have "mechanisms" of evolution. I think that is the proper way to understand it.

so let say if hypothetically a male at twenty years old, doesn't drink or do drugs, doesn't have any illness and is completely normal in physics, then his mitochondria duplicate into 3 mitochondria that does the same thing looks the same and is in the same cell. (ignore the part where energy cannot be create or destroy) this will happen simultaneously in every cell... so would the man die or something?

Animals such as squirrels have year round fur but in the summer I don't understand how they don't die from heatstroke when it's 28-36 degrees.

As in would a chimpanzee from one tribe be able to effectively communicate with another tribe?

As far as I know enzymes only accelerate a chemical reaction but can they also slow down a reaction?

If the balls still exist and the male is well aged to his teenage years, will his body be able to naturally reproduce testosterone after the balls have surgically been brought down to the right spot and matured over time?

So I’m currently getting a associate in biology sciences and I’m looking for my next step in a career. I’m interested in being a medical lab tech or any lab tech. But I’m not completely sold on it. And I’m not sure which should be my next move but I don’t want to waste any more time. I was thinking about continuing my bio degree at a four year university. I just need help finding options or what career paths there are. (Great paying careers)

2. For small fish like mollies, guppies and Neon terra when they encounter a bigger fish is their only hope swimming away? Like to hide and run is their only strategy?

3. For above I had kept big fish alongside them why do they not seem to fear nor swim away? For actual comparison, Pearl Gourami vs Neon tetra and Molly. Why?

In pretty much every sport and activity where you could fall down with some velocity or height people are taught to go against their reflexes of arms out and directly absorbing the blow. But then why is our instinct to fall in an injury prone way in the first place?

Is there a word for this? I want to describe a whole species or population (not an individual) that will not or did not give rise to a new species after them. So they went extinct but their current population might not be exactly one.

English isn't my native tongue so I don't think I'll articulate myself enough to get the answers I need, let me try either way. How does our body/brain know how to balance it? Like even children between the same couple aren't balanced to be half male and half female most of the time, so how is it that the general population is evenly distributed?

Often theirs a focus on how domesticated species have evolved to be able to interpret human emotions and even communicate with us. But have human beings evolved themselves? Adapting to domesticated species in order to better understand or communicate with them?

Just curious. My network cable to my shed has been chewed apart multiple times in 10 years, but not the mains cable once, and theyre both similarly exposed. Near London, UK

I am a graduate student in a new lab. Our lab is attempting to grow an anaerobic bacterial species, and I've had nothing but issues. I do not believe the seal between the top and bottom portions of the box is being maintained properly. The box is a Plas Labs basic glove box and has the two components mentioned above. Both the professor and I attempted to open the box and break the seal at one point to clean the inside prior to use but thought we failed. I am unable to find any information on ordering additional sealant, or what material can be used to seal the pieces of the glove box. Any assistance or experience would be helpful.

Our pets are very smart creatures....ok a lot of them are pretty freaking stupid, but I was watching the documentary mankind the story of all of us again at work and it went over the line in the beginning of the first episode how since we unlocked tool use and cooking we had our stomachs shrink and developed bigger brains.

Cats and dogs are extremely unlikely to, through normal evolution or breeding ever develop tool use and hands. So, they are not going to ever learn how to make a fire and cook their rabbits or mice. But, they don't need to because they have us.

Not only is selective breeding going on, but we might unlock genetic editing in the future that might dwarf anything selective breeding or current crispr ever could. Combined with the fact that we are the ones choosing what their diets are. The diets we give our pets are vastly more healthy for our cats, especially the soft kinds and special treats, so, do you think that in two million years that the pets we will have will be hyper intelligent, basically cave person intellect by todays standards sometime in the far future?

Will house cats in the year 2 million possess the ability to do basic algebra with the millions of years of being pets, being fed super nutritional food and combined with selective breeding and other techniques along the way?
