Answer:
The correct answer or fill in would be- but <u>Change and evolve</u> over time.
Explanation:
The perfect cosmological principle is a extended version of the cosmological principle. The perfect cosmological principle says that the universe is look same from all directions but can be change and evolve with time.
Steady state theory supports this theory as it also says that universe is expanding but also maintain its density even though it continuously creates stars and galaxies but still look same.
Thus, the correct answer is - but <u>Change and evolve</u> over time.
Answer:
1) Sterilize the loop.
2)Flame lip of TSS culture with <em>S. aureus</em>.
3) Remove some bacteria from surface of TSS culture with <em>S. aureus.</em> Remove loop.
4)Flame lip of TSS culture with <em>S. aureus</em>.
5)Flame lip of broth culture tube.
6) Dip loop into sterile TSB and swirl. Remove loop.
7)Flame lip of broth culture tube.
8) Sterilize the loop.
Explanation:
The aseptic technique is a s<u>eries of steps to prevent contamination during manipulations of cultures and sterile culture media</u>. A mastery of aseptic technique is required for maintaining pure cultures, as airborne contaminants are virtually everywhere. Picking an isolated colony and restreaking it is the main method for obtaining pure cultures from liquid samples containing several different organisms and is a common procedure in the microbiology laboratory. Other techniques for obtaining pure cultures have been developed that are especially suited for particular groups.
<u>Answer:</u>
A: Less nitrogen and more phosphorus is required.
Fertilizer requirements changes in the above manner when a crop leaves the vegetative stage and enters the flowering stage.
<u>Explanation:</u>
The vegetative stage is the one when plant starts growing after germination. Plant develops foliage and flourishes. The process of photosynthesis is carried out, and collect different types of resources like CO2, nutrients, and lighting. These are needed during reproduction and flowering. Plants are more delicate at this stage than in the flowering stage.
The final phase of the plant growth is the reproductive stage or the flowering stage. The focus is the production of flowers, fruits, and seeds at this stage. Nitrogen is not at all required at this stage and plant needs other nutrients like Potassium and phosphorus at this stage.
Answer:
Physical Change:
- Boiling water
- Breaking a pencil
- Water evaporating
- Denting a car door in an accident
- Tearing paper
- Ice melting
- dissolving
Chemical Change:
- Something rusting
- photosynthesis
- metabolism/digestion
- Nuclear power [atoms are arranged differently]
- Smashing paper with two metal balls, burns paper
- Electricity in water, breaks H2O into H2 and O2
-----
physical change is when there is only physical change occurring--and it can typically be undone easily,
whereas chemical change is when there is chemical change--which changes the chemical properties of something, which cannot be undone simply.
hope this helps!!
