Explanation:
Boom, here are the correct answers:
- 1. The DNA fragment has a higher molecular weight. (heavier molecules move slower through the gel)
- 3. The DNA fragment has a higher positive charge. (more charge = more interaction with the electrical field)
- 4. The DNA fragment has a higher negative charge. (again, more charge = slower movement)
- 2 is FALSE! Lower molecular weight DNA fragments move faster through the gel, so the fragment that traveled less far in the gel actually has a higher molecular weight.
The DNA fragment that traveled less far has a higher molecular weight.
The DNA fragment that traveled less far in the gel has a higher molecular weight. Gel electrophoresis separates DNA fragments based on their size, with larger fragments traveling a shorter distance. Therefore, option 1 is correct.

bulimia
starvation dieting
obesity
Answer: starvation dieting
Explanation:
The composition of human and animal teeth is calcium and phosphate. The diet of a human affects the condition of the teeth. High concentration of sugars and fats in the food will likely to damage teeth. Also the deficiency of calcium and other minerals essential for teeth development may indicate the signs of eating disorders. Therefore, starvation dieting is the correct option.
The aspect of the scientific process that will decrease the likelihood of publishing low-quality research is : Statistical hypothesis testing
Statistical hypothesis testing is used to determine the conclusion from two different, conflicting hypothesis ( i.e. null and alternate hypothesis ).
This testing is carried out on a determined sample of the population and the difference between the sample and the null hypothesis determines if the results from the the statistical hypothesis testing will be accepted or not, because the null hypothesis is true. i.e.
Hence we can conclude that The aspect of the scientific process that will decrease the likelihood of publishing low-quality research is : Statistical hypothesis testing

Answer:
statistical hypothesis testing
Explanation:
The new drug must be evaluated by statistical tests in order to compare this it with a control (i.e. a placebo). This comparison must be statistically significant to accept the hypothesis that the drug is effective. The statistical significance in these tests is very important since it is the only way to accept a hypothesis with confidence that it is true. If Dr. Besson doesn't get that, their drug will hardly be released.
On the other hand, proving that the drug is safe (i.e no harmful side effects) implies more research and is more difficult to prove.
The cytoplasm is a thick, liquid residing between the cell membrane holding organelles.
The larger the cell, the longer time it takes for materials to travel.
Is how an increase in cell volume impacts the diffusion of materials through the cytoplasm.
B. He encouraged production goals for factories.
C. He allowed capitalism in new economic zones.
D. He introduced rules favorable to factory owners.
Option C i.e He allowed capitalism in new economic zones is the correct answer.
Deng Xiaoping was a great politician and economist reformer who modernized industry in China by allowing capitalism in certain districts which were free trade zones. This made industrialists to invest more in industries which lead to the modernization of industrial sector in china.
He allowed capitalism in new economic zones. hence option C is the correct answer.
The job facing China's leadership, according to Deng, was twofold: I fostering economic modernization in China, and (ii) maintaining the Chinese Communist Party's (CCP) ideological unity and control over the arduous reforms necessary by modernization.
Deng Xiaoping was a brilliant politician and economist reformer who helped modernize China's industries by introducing capitalism in specific free trade zones. This encouraged manufacturers to spend more in their businesses, resulting in the modernization of China's industrial sector.

The formation of metamorphic rocks takes place when either sedimentary or igneous rocks are subjected to immense pressure and heat.
Further Explanation:
Rocks are found on earth as metamorphic, sedimentary, and igneous. The name is based on how these rocks are formed. The shells, sand particles, and pebbles form the sedimentary rocks. These particles are called sediments and their accumulation into layers results in the formation of rocks as they gradually harden over time. The igneous rocks are formed as a result of cooling followed by hardening of magma under the Earth's surface. The metamorphic rocks are formed due to metamorphosis which takes place below the surface of the Earth as a result of application of heat and pressure.
The change of one rock type into another over a period of time is termed as metamorphosis or rock cycle. The increase in pressure and heat due to stress can change a solid rock into a new type of rock. The temperature increases because of the deeper buried layers of sediments below the Earth's surface. As the layers descend the temperature increases gradually for every proceeding kilometer. The temperature becomes even hotter as the layer turns deeper. As the weight of every subsequent layer increases, it also increases the pressure which in turn causes a further increase in temperature.
Metamorphism can occur in two ways:
1. The rocks come in contact with each other as the plates slide over one another producing a shearing effect. This causes the descending rocks to change.
2. The descending rocks might also melt due to friction. The melted is considered as the igneous rock but the rock adjacent to it might become a metamorphic rock due to the production of heat.
