Scientists are trying to determine the effect of mass on the force of gravity between two objects. In this experiment, then scie

ntists use the following procedure: 1) Place two large, empty barrels exactly 1m apart. 2) Measure the gravitational force between the two barrels and record in data table. 3) Add 10kg of water to each barrel. 4) Measure the gravitational force between the two barrels and record in data table. 5) Repeat steps 3 & 4 until the barrels are completely full of water. 6) Create a graph of Gravitational Force vs Mass from the data collected. What should the graph from Step 6 look like? A) A B) B C) C Eliminate D) D

What is the theory of natural selection, and why does it occur in an organism? Give an example.
BlackZzzverrR [31]

Answer:

It occurs in organisms because an organism with a beneficial trait/mutation have a higher chnace of surviving compared to organisms that do not. So the organsims that do survive pass on their genes to the next generation, and the bext generation will pass on those genes to the generation after and so on. But all the organisms that do not possess a beneficial trait/mutations will not survive, therefore they cannot reproduce and pass on those genes to their offspring. This means that most of the population will posses that trait/mutation.

Example: Spotted moths camouflage with bark so they are seen by predators and eaten. Black moths are easily seen by predators and are eaten. Spotted moths then pass on their genes to the next generation of moths.

In what type of immunity will the defenses be triggered and react in the same manner, regardless of the organism invading
GalinKa [24]

Innate immunty

Explanation:

  • Innate immunity is a kind of immune response that is existing in our human body which is automatic and non- specific.
  • These defenses start to fight off pathogens before they start the effective action.
  • Innate immunity appears into action immediately when an antigen's presence is detected in the body.
  • It includes physical barriers like skin, chemical compounds in the blood and immune system cells like epithelial cells, that attack the foreign cells in our human body.
  • It is also known as Natural immunity.
