COVALENT BONDS . In a covalent bond, electrons are shared between two atoms . When two oxygen atoms bond together to form an oxygen molecule, they share four electrons - two from each oxygen atom. Other examples of covalent bonding are water (H20), and carbon dioxide (CO2).
What happens to the kinetic energy of a snowball as it rolls across the lawn and gains mass.
Kinetic energy of a snowball will increase as it rolls across the lawn and gains mass. We already know that Kinetic energy is directly proportional to speed. We can express kinetic energy by the formula Kinetic energy = 1/2 mv^2 Now as the mass increases and the velocity remains constant, the kinetic energy of the snowball is bound to increase. I hope the explanation has helped you.
Kinetic Energy Increases

I NEED HELP PLEASE The ability to use old cells is an advantage of _____. hybridization DNA testing restriction fragment length polymorphism (RFLP) polymerase chain reaction (PCR) all DNA testing procedures --------
Which of the following is an example of genetic discrimination? Miranda's doctor asks her to take a genetic test before she gets pregnant. Wesley pays more for his insurance than his younger brother. Veronica is cut from the swim team because of poor grades. Timothy does not get a promotion at work because he has cancer. -------
Which of the following statements is true? Offspring from recombinant DNA are genetic copies of their parent. Selective breeding is controversial because it creates sterile offspring. Recombinant DNA combines genes from two different organisms. Natural selection is the oldest form of genetic engineering. ---------
Which of the following statements is true? Some DNA tests analyze the mitochondria instead of the nucleus of a cell. Inconclusive DNA test results indicate usually means the suspect is guilty. The most common biological evidence used in DNA testing is sweat. DNA testing cannot be done on cells that have been dead for more than five years. ---------
Selective breeding _____. creates offspring which are genetically identical to the parent is the process of breeding only organisms with desirable traits involves the removal of the nucleus of a cell combines traits from organisms of different species ------
Fritz has a DNA test to determine if he shoplifted from a local convenience store. The test results are inclusive. This means Fritz_____. has an identical twin was at the scene of the crime is not guilty of shoplifting has never been to the store
Kindly see below answers: 1. The ability to use old cells is an advantage of all DNA testing procedures such as hybridization DNA testing,restriction fragment length polymorphism (RFLP), and polymerase chain reaction (PCR) 2. The answer is "Timothy does not get a promotion at work because he has cancer." This is clearly an example of genetic discrimination 3. The answer is "Recombinant DNA combines genes from two different organisms." 4. The answer is "Some DNA tests analyze the mitochondria instead of the nucleus of a cell." 5. The answer is "is the process of breeding only organisms with desirable traits" 6. The answer is "was at the scene of the crime"
just use the question for that question not the whole entire thing
What is cell theory?
Here are the main theories of the cell theory.
1. All living organisms are composed of one or more cells.
2. The cell is the basic unit of structure and organization in organisms.
3. Cells arise from pre-existing cells.
cell theory states that the cell is the basic unit of living organisms. Before the discovery of the cell, people were unaware that living organisms were made of building blocks of cells
