A singularity did.
A singularity is an infinitely small and infinitely dense point of matter from which the universe came. The big bang theory suggests that the big bang was like a balloon inflating from that infinitely tiny point into the universe we know today. There is plenty of evidence about this.
Answer:
Its B-Contaminated hope this helped in any way!!! have a nice day!!
Explanation:
Answer:
1. Mother: TtRr Father: TtRr
2. RT, Rt, rT, rt
4. Possible combinations: RRTT, RRTt, RRtt, RrTT, Rrtt, RrTt, rrtt, rrTT, rrTt
(combine them on the chart, for example, the first one on the left would be RRTT)
5. 9:3:3:1
Explanation:
Based on the broth left on an open flask experiment, wherein the boiled broth was placed in two flasks (one flask with straight neck and the other flask has a bent neck) and exposed to open air at room temperature for several weeks.
The broth within the straight neck flask has changed its appearance. It became discolored and cloudy. Whereas, the broth in the bent neck open flask still remains the same.
These results would then support the conclusion that germs in the air were able to fall unobstructed towards the straight neck flask and contaminate its contents. While, the bent neck of the 2nd open flask acted as a trap for the germs, preventing the germs from contaminating the broth. Further emphasizing that germs can only come from other germs and not from spontaneous generation.
Explanation:
1. A decrease in the number of greenhouse gases that humans produce will result in lowered global temperatures. This will allow the ice sheets in the polar regions to increase increasing also albedo.
2. Using light-colored building materials on houses and pavement in urban centers will work towards increasing albedo as more sunlight is refelcted back by built environments.
3. Decreased deforestation/increase in aforestation increases the earth’s sirface albedo because vegetation reflects back more sunlight than the earth’s bare surface.
