Was Frederick Douglas a famous scientist?

No, he was a negroe freedom fighter during the pre and post civil war era's. Some may consider him a scientist because without him, the slaves wouldn't have had a strong voice in politics, he had a degree in math and science though, if you were wondering:)

How did janssen's hooke's and leeuwenhoek's work contribute work contribute to the discoveries of the later scientist?

There work is known for their work on the improvement of the microscope and for their contributions towards the establishment of microbiology. Leewenhoek used his handcrafted microscopes and was the first to observe and describe single celled organisms, which he originally referred to as animalcules, and which we now refer to as microorganisms. He was also the first to record microscopic observations of muscle fibers, bacteria, spermatozoa and blood flow in capillaries. Hooke published Micrographia, a book describing his microscopic and telescopic observations, and some original work in biology. Hooke coined the term cell for describing biological organisms, the term being suggested by the resemblance of plant cells to monks' cells. Hans and Zacharias Janssen created the compound microscope and invented the lenses used by Leeuwenhoek. They also helped make cells come alive as one of three inventors of the first modern microscope.

Why do scientists organize organisms into groups?

Because there are countless numbers of animals and having an organized, internationally recognized system of classification allow scientists to put new-found creatures into previously made categories.


Answer:

Scientists use DNA to place animals into groups.

How have scientists started to study relationships between differet groups of organisms?

Scientists most certainly have studied all sorts of relationships that different organisims share with each other, but I guess you could say that 'relationships' is a very wide term.

Scientists, depending on the organisim, would've researched and studied how they interact with not only their birth species but other species organisms as well. The amount of research would depend on the species.

If the term 'relationships' that you are trying to specify involves romantic or mating purposes, than scientists have also invested quite a lot into this as well. They have done quite a lot in terms on how species can possibly mate with each other, but this has pretty much always been done in a labotory and never observed in the wild under natural circumstances. In rare cases in a few species, the offspring, if they have been managed carefully, can be born but will be infertile and unable to reproduce and produce young. E.g, Lions and Tigers have been mated and had an infertile cub, known as a 'Liger.'

However, there has been exceptions, but mostly with species that are very closely related and most of the time, have evolved with the help of scientists over time into domestic breeds. E.g. Most breeds of domestic cats and dogs are able to interbeed.

Is Neil deGrasse Tyson dead?

As of my last knowledge, Neil deGrasse Tyson is alive. He is an astrophysicist, author, and science communicator who is active on social media and continues to engage in public speaking engagements. It is always a good idea to verify this information through a reliable news source or his official social media accounts for the most up-to-date information.

Can you tell me who is kitaw ijigu?

Ethiopian born scientist who worked at NASA and developed the GPS system.

Which is a journal in which scientists publish original scholarly research?

Biology in General and Ecology are both scientific journals that allow scientist to publish articles. An added benefit is the fact that some journals also peer review the articles.

How would your understanding of earths past change if a scientist discovered a mammal fossil from the paleozoic Era?

Finding a Paleozoic fossil would change our thinking completely, we would have to rethink the entire evolution of animals and the conditions on Earth all the way back to and including the Paleozoic. That is 500 million years of geologic history to rewrite.

Who was the scientist that developed a new model of planetary motion?

Isaac newton discovered the three principles of planetary motion

What was Robert Koch religion?

He was not as reliogioud man although baptized Lutheran.

Why did mercuric oxide in lavoisier's reaction chamber weight more than the mercury metal?

The air surrounding said mercury metal was absorbed into the mercury at the higher temperatures, therefore causing the new substance--mercuric oxide--to weigh more.

How would a scientist use a landsat satellite image to determine the amount of pollution being produced by a city?

There is no direct way to measure pollution produced by a city with

Landsat data, but you could calculate the extent (area) of the

city and then potentially extrapolate pollution based pollution-per-area averages.

For more on Landsat & urban growth, see the related link below.

What famous scientist had a low IQ?

The famous scientist that had a low IQ was named: Jin Choi Wong.

He inventing the automatic toothbrush, and the spray bottle.

Hope this helps! :)

Who first coined the word satellite?

Satellite comes via French satellite from Latin satelles 'attendant,escort', which itself probably went back to Etruscan satnal. Its use for a 'body orbiting a planet' is first recorded in English in 1665, and comes from the astronomer Johannes Kepler's application of Latin satelles to the moons of Jupiter.

What is the modern version of these cells called?

The modern version of these cells is called a virus.
