Answer:
Radioactive isotopes has a characteristic half life that is ranging from less than a second to million of years.
Explanation:
One of the characteristics of radioactive material is that the radio active isotopes instantly gives off particles. This process is termed as radio active decay.For this activity pennies are used pennies headed up it means that nuclei have undergone radio active decay, or tails up it means that nuclei that haven't yet decayed.
Answer:
(C) Only BamHI and BglII fragments are compatible.
Explanation:
First we can visualize how the enzymes cut by completing the strand below and cutting where indicated. The three enzymes cut with cohesive ends.
Then we can complete the sense of the strands and serach compatible ends. Keep in mind that we can only join 5 'ends with 3' ends.
BamHI = G...3' 5'...GATCC
CCTAG...5' 3'...G
XbaI = T...3' 5'...CTAGA
AGATC...5' 3'...T
BglII = A...3' 5'...GATCT
TCTAG...5' 3'...A
In bold, leave the bases that remain in single strand and must be compatible with those of the other end.
To be compatible they must be complementary bases. A with T and C with G.
Now you can see that only BamHI fragments are compatible with those of BglII.
<span>False. Wetlands and Estuaries do require protection as they are easily susceptible to pollution and dumping. Because these lands are difficult to patrol and do not have any commercial use, it is common for unethical parties to use them to either dump wastewater or large amounts of solid trash to try and hide and cut costs. Without legal protection they would quickly be destroyed.</span>
Answer:
The correct answer is 50%.
Explanation:
In the given question, the table says that fruit color is determined by the incomplete dominance of allele R and R'. In the case of RR genotype the fruit color will be red and R'R' the food color will be yellow but in the heterozygous condition the color would be orange, so the cross between RR' and R'R' would be as follow:
Punnett square:
R R'
R' RR' R'R'
R' RR' R'R'
It is found by the given cross that the cross between RR' and R'R' would form two orange fruit plants out of four which is 50%
A laboratory report form should indicate when a specimen has been collected by capillary puncture because certain test outcomes change depending on the specimen source.
<h3>What is capillary puncture?</h3>
For certain tests that call for small amounts of blood, people of any age may undergo capillary puncture or capillary sampling from a finger, heel, or (rarely) an ear lobe. The procedure is, nonetheless, frequently utilized on pediatric patients. For capillary testing on an adult patient, the finger is typically the first choice. Heel's sides are only used in young and neonatal patients. In surveys or research projects, ear lobes are occasionally employed.
