Answer:1.c 2.d 3. d
Explanation:
The DNA hyperchromic effect can be defined as the absorbance of radiation or light by the nitrogen bases of DNA. This phenomena is effective when the DNA is in single stranded condition. For observing the hyperchormic effect the DNA is required to be denatured at high temperature or by increasing the level of pH.
The two strands of the DNA when get separated the absorbance of the DNA solution also increases. This results due to reduction in the base-base interaction and hence, increases the absorbance of light like UV by the bases.
C is incorrect
Both acids and bases produce ions in solution, are electrolytes, and conduct electricity in solution. Although red litmus is an indicator, it does not change color in an acid, acids are proton donors while bases are proton acceptors. Soaps often contain bases, not acids.
D) conduct electricity in water. is the correct answer
The Big Five trait dimension or the five factor model is based on descriptors of personality. The big five traits are:
Openness
Beuroticism
Agreeableness
Extraversion
Conscientiousness
From these, the trait expressed is Extraversion. This trait is characterized by outgoing and energetic behavior. Energy creation is gained through external means.
Hi there!
Kinetic Energy (1/2 · mass · velocity²) occurs when an object is in motion, or a force is occurring on the object. An example would be a car in motion.
Potential energy (mass · height · gravity ) is obtained when an object has the ability to do work. An example would be an object on a shelf. It has the potential to fall, and this would cause the potential energy to become converted into kinetic energy.
-----------------------------------------------------------------------------------------------------------
Looking at the examples in the table, we can sort them as such:
Girl swimming laps- Kinetic energy because the girl is in motion.
Boy on diving board - Potential energy because the boy is not in motion, but has the potential to be in motion.
Girl hitting volleyball - Kinetic energy because the volleyball is in motion.
Boy holding volleyball- Potential energy because the volleyball is stationary and has the potential to be in motion.
Therefore, the correct table is table 1.
Answer;
They have revealed new information about cell structure and processes.
Explanation;
-The Cell Theory states that, All living things are made up of cells, Cells are the basic units of structure and function in living things, and that new cells are produced from existing cells.
-Most microscopes use lenses to magnify the image of an object by focusing light or electrons.
-The Invention of the Microscope helped the development of the cell theory because it allowed the scientists to actually discover that everything was made up of cells, and what cells do to come up with that theory. If the scientists did not see that cells existed, they could not have observed the cells easily and they would not be able to construct the cell theory.
