Cellular respiration classified as________respiration,occurs in the__________.
Answer:
1.a combustion reaction
2.inside of cells
Explanation:
Although cellular respiration can be classified as a combustion reaction (thanks to its release of energy in the form of heat), because it occurs inside of cells, the energy is released in slow bursts, and only after a series of reactions and processes. As cellular respiration occurs, it produces CO2, carbon dioxide, as a waste product.
In the early 1900s, Thomas Hunt Morgan was among the first scientists to contribute to the chromosome theory of heredity. Morgan’s investigations into heredity in fruit flies led him to propose that the event represented in the diagram sometimes occurs.
Which statement about the event presented in the diagram sometimes
occur?
A. The event represents DNA translation in the smooth endoplasmic
reticulum.
B. The event takes place in the bacterial cell.
C. The event produces genetically identical daughter cells.
D. The event provides genetic diversity in eukaryotic cells.
The statement about the event presented in the diagram sometimes occurs - D. The event provides genetic diversity in eukaryotic cells.
The given event in the diagram is known as crossing over which takes place during the process of meiosis.
Crossing over takes place during the pachytene stage of Prophase I of Meiosis I where the non-sister chromatids of homologous chromosomes exchange genetic materialthis results in the recombination of the genetic material and creates a new genetic combination.Thus, genetic variations occur which can be beneficial to the offspring.Thus, the statement about the event presented in the diagram sometimes occurs - D. The event provides genetic diversity in the eukaryotic cell.

7. Mateo and Jackie were on a playground rolling some different sized balls to get them to crash. They
used a tennis ball (the same mass) in both crashes. They tried two Soccer balls-a pink one (more
mass) for Crash l the and a blue one (less mass) for Crash 2.
Answer:
b
Explanation:
beacuse it b and ghcgdd
The answer is A
This is because since the pink soccer ball has a larger mass than the smaller blue soccer ball, it would take a stronger force to move it than it would for blue soccer ball.

According to the scientific theory of atoms, which of the following statements best describes the location of electrons? A. in the nucleus of the atom B. both in the nucleus and around it C. outside the nucleus and often far from it, in the electron cloud D. outside the nucleus, yet very near it because they are attracted to the proton
Answer:
D. Outside the nucleus, yet very near it because they are attracted to the proton
Explanation:
Electrons are located outside of the nucleus of the atom, which is made up of neutrons and protons. In physics, the space they take up is informally referred to as the electron cloud. Protons and electrons are attracted to each other, because the positive electric charge of the protons is attracted to the negative charge of the electrons. This is why the electrons are very close to the nucleus.
The best statement that describes the location of electrons is D whichis Outside the nucleus, yet very near it because they are attracted to the proton.
What is electron?An electron is a negatively charged subatomic particle. It can be either free , or bound to the nucleus of an atom.
Electrons in atoms exist in spherical shells of various radii, representing energy levels. The larger the spherical shell, the higher the energy contained in the electron.
Thus, option "D" is correct.

how do we get our energy? How is that energy converted from potential to kinetic energy?
Answer:
When an object is allowed to fall, the concentrated gravitational potential energy is converted into the kinetic energy of motion.
Explanation:
Answer:
hope this helps :D
Explanation:
Kinetic energy is energy an object has because of its motion. A ball held in the air, for example, has gravitational potential energy. If released, as the ball moves faster and faster toward the ground, the force of gravity will transfer the potential energy to kinetic energy.
