What kind of tools does an astrobiologist use?
Well there aren't many tools exept the few robots to scan for DNA?CARBON life as well as non-DNA and Hydrogen oxide life.
We also have orbiters which moniter the planets in space looking for leaks on the surface in which many elements of Water, Silica, or Hydrogen may escape fueling life on mars or a newer planet of suspision Jupiter

How long have human beings existed?
200,000 years ago
Human have existed for roughly half a million years, but this answer depends on the exact definition of "human". Fossil evidence shows that several human-like lineages developed during the past million years or so. >From fossils, the appearance of Homo sapiens is dated at about half a million years, and of anatomically modern Homo sapiens at about a hundred thousand years, values that are also supported by genomic evidence. Another data point, although not something you asked directly, is that the recent complete sequencing of the genome of the chimpanzee, which is the closest living relative of humans, suggests that chimps and humans diverged from their common ancestor about 6 million years ago. Of the many intermediate related species that have existed since then, only chimps and modern humans survive today.

Which is a better sailboat a Beneteau or a hunter?
Both Beneteau and Hunter are reputable sailboat manufacturers, each with its own strengths and features. The choice between a Beneteau and a Hunter depends on your specific needs, preferences, and sailing style. It's recommended to research and test sail both brands to see which one best suits your requirements.
How long ago did cavemen live?
Caveman as the stereotype has them generally didn't exist-people generally lived in huts and before that just lived in the wild. The nearest we get to the stereotype of the caveman was the neanderthal. They started about 600,000 years ago to 33,000 years ago, when they became extinct and Homo Sapiens Sapiens became dominant.
I would assume a simple, but long wooden trowel similar to a mortar trowel, perhaps with some upturned skids at the end so overlapping strokes do not make unwanted marks in the plaster.
I have seen how Indonesian labourers apply cement rendering in Jakarta (live there) many many times- and they get perfectly smooth surfaces with minimal & rather primitive hand tools- so I'd assume the process is very much the same- for both internal and external walls. This has been a construction process here dating back at least 400 years according to one palace restoration foreman.
They 'throw' with moderate force large globules of the render onto the wall 20cm widths at a time, then smooth it immediately over with a mortar trowel- each throw overlapping the next. Once the labourers have roughly attached the render well, another worker with a long straight-edge plank screens over the wall to remove any bumps and detect unwanted dips.
The final labourer uses a string line attached flush with the upper-most )same plane) corner of the wall and uses this plumb line to carefully scrape off excess render as it is maybe 50%+ dry. Final touch up applications are made to the small air bubbles.
Summarily- it can be done- and superbly with simple hand tools- it just requires a lot of patience.
Did our ancient ancestors sleep sitting up?
It would have been prudent for Neanderthal and Cro-Magnon man to sleep in a sitting up position. Weapons against animals that attacked them for food could be kept close by easily accessible before they had fire to keep them away. They would have put their backs against a stone wall of a cave more because of the room needed to accommodate their numbers and so sitting up sleeping solved at least 2 problems faced by our ancestors.
Infertility indicates the condition of not being able to get pregnant after one year of trying. Or, six months, if a female is 35 or older.Females who can get pregnant but are unable to stay pregnant may also be infertile.
Pregnancy is the result of a biological process that happens through the following phases:

Was there autisism 100 years ago?
Yes but 100 years ago doctors would have called it something else, like 'your child is a bit stupid'. The same goes for the other newer conditions like dyslexia and attention deficit disorder. In another 100 years it will no longer be called autism as this will be further sub divided into other diagnosis.

What two land masses did pangaea break up into and how many years ago was it?
Pangaea broke up into Laurasia (northern landmass) and Gondwana (southern landmass) around 175 million years ago during the Mesozoic Era.
It's possible that the water pump is failing or that there is a blockage in the cooling system. I would also recommend checking the radiator hoses for leaks or restrictions and ensuring that the cooling fans are functioning properly. It may be helpful to have a mechanic perform a pressure test on the cooling system to identify any potential issues.
What is the trick to removing a kitchen faucet sprayer retaining clip which looks like a flat C?
Use a butter knife to pry it off. Insert the blade of the knife between the clip and the plastic below it and then use a gentle upward prying motion, kind of like using a bottle opener. Use the side, not the tip of the blade.
push it to the side where the opening will slide out.
I don't get that answer. http://www.rd.com/content/openContent.do?contentId=17901 has some good advice. I like their suggestion you do this when the hardware store is open since you'll probably be making a couple of trips for things you don't have.
I just replaced my faucet. First, I sprayed the nut holding faucet in sink from underneath with WD-40. (Don't let it drip in your eyes.) I turned off the water. Then, since I was going to throw the old faucet away, from under sink, I bent the copper water tubes back and forth so they broke off as high as possible (above nut holding faucet to sink). I undid flexible tubing so it could be pulled up as high as possible from sink end to get it out of the way, too. Then there was room enough to grab the nut and turn it counterclockise. I used a basin wrench, but small adjustable wrench or vice-grips probably would have worked, too. I had to grab the large washer and nut together and turn them at the same time at first.
I also had problems with that answer. I was trying to replace just the sprayer head - not the entire hose - on my kitchen sink when the confounded retaining clip completely halted progress. Every article I read said something along the lines of "merely slide the clip off," or "this is so easy, even a caveman can do it." Perhaps they were working with a type of sprayer head assembly not available in my part of the world????
I ended up prying the darn thing out with one of the pointy awl-like attachments on my leatherman. I couldn't get needle-nosed pliers to grab it, and a butter knife (a suggestion from another website) wasn't even a possibility. It took at least a half hour, (one or two bloody knuckles and some choice swear words) and I gouged the heck out of the old nut and took a fair bit of plastic off the hose before I could get it off. However, when I put the new sprayer on - everything seemed to work and there are no leaks.
I subsequently tarred and feathered the old retaining clip when I was finished.
I was struggling with the same issue. I used a steak knife, which has a thin, pointed tip, and pried that under the back edge of the clip. That gave me the ability to get under the clip, and it slipped off with no problem.
Can you be a family man and a repo man at the same time?
Being a family man and a repo man can be challenging due to the demanding nature of the repo job, which may conflict with family responsibilities. Balancing both roles would require effective time management, clear communication with family members about the job demands, and ensuring that the repo work is conducted professionally and ethically. Ultimately, it depends on individual circumstances and priorities.
What kind of tool do you use to loosen tension pulley on a 2002 cavalier?
You would typically use a serpentine belt tool or a breaker bar with the appropriate socket to loosen the tension pulley on a 2002 Cavalier. These tools help you apply enough force to release tension on the pulley so you can easily remove or install the serpentine belt.
What is the process of throwing a spear?
In throwing a spear, there are two things to keep in mind: Accuracy, and Distance. You can throw for distance, but have little to no accuracy. You can throw for accuracy close up, and be successful, but at close distances, it's more of a lance, than an actual spear. For both accurate, and good distance, you will need to practice; Balance-Centering the spear in your hand in such a way that with no grip the front, and back sit level. Strength- Pulling back as far as you can with your throwing arm, using your other arm out stretched as a counter balance, and increased power. Think "trebuchet". Aim- Using both eyes, focus directly on the smallest part of the target that you desire to hit. Aim small, hit small. At the completion of the throw, your throwing hand should be pointed at the target. You can practice with haybales, and paper targets at first, trying a distance of 25 yards, working to increase that to a little more each time. Each spear has a different balance, and a different minute of angle (MOA). A Samburu spear will not throw like an Assegai, and certain "spears" are in truth "lances", so throwing those will feel like throwing a rock. A German Boar Spear comes to mind. Enjoy a new found hobby!
Do European types owe their physical characteristics to Neanderthal interbreeding?
Yes, to some extent. Modern humans of non-African descent have inherited a small percentage of their DNA from Neanderthals through interbreeding. This interbreeding likely contributed to certain physical characteristics, such as skin, hair, and eye color, found in European populations today. However, it is important to note that Neanderthal DNA constitutes only a small portion of the overall genome.
What is the lifestyle of the US?
The lifestyle in the US is diverse and varies depending on individuals and regions. However, some common characteristics include a strong emphasis on work-life balance, consumerism, individualism, and a focus on personal freedoms and opportunities. Americans tend to value convenience, leisure activities, and a high standard of living.
What was the first controversy sparked by Neanderthals?
One of the first controversies surrounding Neanderthals was their classification as a separate species from modern humans. Initially, some scientists argued that Neanderthals were a subspecies or a primitive race within the Homo sapiens lineage. However, subsequent research based on fossils and genetic evidence supported their designation as a distinct species, Homo neanderthalensis.
What did the neanderthals do in the day time?
Pretty much what you would do if you and a bunch of friends were dropped in the middle of prehistoric earth; make sure you had shelter for the night, keep an eye out for predators, find or collect water from a source, gather food and other resources your camp needed like wood, hunt for meat and fur, sleep, and spend time with one another to keep the stress of uncivilized life from getting to you all.
All of the above takes a lot more time (enough to fill the whole day) when is just you and your own ingenuity.
What are the 4 components of our lifestyle?
The four components of our lifestyle are physical activity, nutrition, sleep, and stress management. These components are interconnected and play a crucial role in maintaining overall health and well-being. By balancing these aspects, individuals can optimize their lifestyle and enhance their quality of life.
Either because of climate change, or competition from Cro-Magnon man (modern humans).
Who is closest relative to modern humans?
Homo erectus is the closest known relative to modern humans.
Did Neanderthals and humans co exist?
Of course they did! Scientist have found fossils that are dated to about 600,000-350,000 years ago.
For that matter, "neanderthals" were human, Homo sapiens neanderthalensis. They are considered a subspecies... about as closely related to modern humans as dogs are to wolves, for example.
In construction, as our nearest genetic cousin homo sapiens neanderthalensis (occasionally classified as not a subspecies, but a new species homo neanderthalensis), the Neanderthals were extremely similar to our current species, home sapiens sapiens.
Body-wise, Neanderthals were virtually identical to modern humans, being just slightly shorter on average than contemporary humans of the time. They were a bit more stoutly built, having slightly thicker bones structures and anatomical arrangement, and analysis of their stature and bones have indicated that they carried a strong musculature, probably being 10-20% stronger than a comparable human. Contrary to popular belief, Neanderthals had at least an equal brain size as humans, with modern studies suggesting that adult Neanderthals actually had a slightly larger brain size.
A good breakdown of all the physical differences can be found on the Wikipedia link below.
Of course, we can't be sure what a living Neanderthal looked like, because fleshy parts have never been discovered (i.e. we've never found a mummified Neanderthal body). However, anthropologists think that they varied as much as humans in exterior looks.
