Answer:
A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes. Often, the genes carried in plasmids provide bacteria with genetic advantages, such as antibiotic resistance.
A gene is spliced by assembling different gene segments and DNA sequences into a product called a chimera. Scientists join these snippets in a circular piece of DNA called a plasmid. Scientists use a complex process to clone genes from an organism's DNA.
Hot air always rises from the equator. As this air climbs higher in the sky, it cools. Cool air can hold less water than warm air. This means that as the air cools, clouds form that release most of the water they hold. Because the cooling air is above the equator, the moisture rains back down on the tropics.
Answer:
207 ° C
Explanation:
De;
P1 / T1 = P2 / T2
Luego;
P1T2 = P2T1
P1 = I presión inicial = 7.5 atmósferas
T1 = temperatura inicial = 15 ° C + 273 = 288K
P2 = presión final = 12,5 atm
T2 = temperatura final =?
T2 = P2T1 / P1
T2 = 12,5 * 288 / 7,5
T2 = 480 K -273
T2 = 207 ° C
Answer:
96000YEARS
Explanation:
Given that 1/28 = 8 half lives
this means that 8 half lives ,
and the given fossil should have 1/28 of the isotope
8 half lives = 1200 x 8
= 96000years
therefore the predicted Neandertal fossils is 96000years
