Explanation:

A property which does not bring any change in chemical composition of a substance is known as physical property.

For example, blood is more viscous than water, its pH is slightly alkaline, its temperature is about 38^{o}C (100.4^{o}F)  .

On the other hand, a property which changes chemical composition of a substance is known as a chemical property.

For example, precipitation, reactivity, toxicity etc are chemical property.

Sometimes, the change in color of a substance can also occur due to a chemical change.

Thus, we can conclude that following are the physical characteristics of blood.

  • it is more viscous than water.
  • its temperature is about 38^{o}C (100.4^{o}F).
  • the pH is slightly alkaline.
  • it is about 8% of one’s total body weight.

  1. Biologist and astronomer both use tools that magnify  so they are able to view minute objects. Astronomers use telescopes while biologists use microscopes.
  2. They both require data science due to the enormous data they are collecting that needs to be analyzed. Astronomers are collecting data on millions of stars and galaxies. Biologists require data science to analyze the enormous genomic data from populations.
  3. Both fields involve making new  discoveries due to the enormity of the scale in their scopes. Biologists and astronomy attempt to find new planets and those that could harbor extra-terrestrial life while biology attempts to find new undiscovered species of organisms on earth.
