When we talk about the history of science, we usually talk about individuals who contributed to scientific discoveries. Is this

a good or bad way of thinking about science? What are some pros or cons?

Describe how climate would be influenced if:

madam [21]

The rate of energy coming from the Sun changes slightly day to day. .It has been suggested that changes in solar output might affect our climate—both directly, by changing the rate of solar heating of the Earth and atmosphere, and indirectly, by changing cloud forming processes.
The axial tilt angle affects climate largely by determining which parts of the earth get more sunlight during different stages of the year Likewise, during winter for the northern hemisphere, there would be fewer hours of daylight because the northern hemisphere would essentially be pointed away from the sun.
If an asteroid were to strike land or a shallow body of water, it would eject an enormous amount of dust, ash, and other material into the atmosphere, blocking the radiation from the Sun. This would cause the global temperature to decrease drastically.
The Sun's irradiance has its greatest effect on Earth's upper atmosphere, while the lower atmosphere insulates Earth from the increased heat. If the Sun were driving Earth's warming, one would expect to see that upper atmosphere getting increasingly hot.\

Why are embryonic stem cells useful for treating diseases

astraxan [27]

Embryonic stem cells are pluripotent cells that are derived from the inner cell mass of a blastocyst before implantation. These cells have potential of treating a wide range of diseases and conditions, which is attributed to the fact that they have; self renewal property meaning that they can ploriferate indefinitely, the cells also have the special ability to differentiate into cells with specialized characteristics and functions. In addition the cells are unspecialized and therefore they can give rise to specialized cells.

Explain how water's cohesive and adhesive properties are a result of its bonding among the atoms

vladimir1956 [14]

Water is a unique molecule which contains inter-molecular forces like vandar wall's forces and hydrogen bonding that results in extremely strong bonding forces among water molecules.

Cohesion and adhesion are the properties of water which refer to the fact that water molecules are not only very strongly attracted to water molecules but also to other polar molecules of any type.

This is the cohesive nature of the water which makes water a water drop and it is the adhesive nature of water due to which water takes the shape and available space in a glass or jar of water .

How these properties are a result of bonding between atoms?

Cohesive properties:

We are well aware of the fact that water is composed of one atom of oxygen and two atoms of Hydrogen.
The two hydrogen atoms align themselves in such a way that oxygen is in middle of them. Due to great electronegativity difference Oxygen gets a partial negative charge while Hydrogen atoms get partial positive charges.
Now one oxygen atom of one one water molecule attracts the partial positive charged hydrogen atom of another water molecule, and this attraction causes the bonding. This type of inter-molecular forces of atom gives water cohesive properties.

Adhesive properties:

If we talk about adhesive properties through which water is attracted to other materials of polar nature, these adhesive properties are also due to same nature of bonding.
Any polar compounds can easily get bonded with water due to polar nature of water molecules. You can see the attached figure for better understanding of bonding properties of water.

Hope it help!

What happens to the genetics of a population when an invasive species enters

tekilochka [14]

Long term: I could either help a species have more genetic variation or wipe out an entire species. Short term: it could decrease food resources for other species.
