Identify the characteristics of life

Identify the charecteristics of something scientific.

Identify whether this is living or not.
Viruses are organized proteins and nucleic acids. They invade cells and use the cells to help them reproduce. Once a new virus is assembled, it does not change size or contents. Viruses themselves do not use energy, but rather rely on their hosts to do the work for them. Viruses do not respond to a stimulus in the environment.

Identify whether or not this situation is scientific.
When the winds get very strong, Brandon observes that his mean, old neighbor is dancing and chanting in his living rooms. He concludes that he is using magic to bring on the dangerous winds.

Define Constants

Define Independent Variable

Define Dependent Variable

Identify the independent variable, dependent variable, constant, and control of the following expirement.

Several members of the Denver Nuggets have a theory that their agility on the court is affected by the types of shoes that they wear. Each player has the same type and make of shoe; the Jordan Retro 7, the Nike KD 9, and the Under Armour's Curry 2.5. Normally players wear the KD 9 for practices and games. The players first ran a 1000 m dash on the same track, wearing the KD 9's. They recorded their times. They waited another 30 minutes, switched to the Curry 2.5 shoes, ran the same 1000 m dash, and recorded their times.

What do we all bonds that form between different water molecules?

Why is ice able to float in water, instead of sink/ Explain how the density changes when liquid water freezes.

Which of these do NOT describe responding to the environment?

A: Responses over a short period of time
B: Temporary responses to conditions, such as shivering when cold or sweating when hot
C: Permanent genetic changes that affect a species over a long period of time
D: Responses needed to maintain homeostasis

True or False: Animal cells have a cell wall and chloroplast.
