red neutrons. How did
Chadwick's discovery change the atomic model?
A The new model showed a negatively charged nucleus.
B. The new model showed a neutrally charged nucleus

Answer:

D

Explanation:

It can't be A as nuclei must be positive.

It can't be B as nuclei must contain at least one proton, and no electrons.

Technically C may be true, but the question is asking about the nucleus. Not the electron cloud. Electrons aren't found in the nucleus. Only protons and neutrons.

Discuss how changes in organisms within an environment affect their survival. Specifically discuss the effects of a gene mutatio
Colt1911 [192]
By changing the color of a beetle, this could cause disruption in which animals consume the beetle. A specific pattern could possibly mimic one of a poisonous beetle, thus reducing the amount of beetles eaten. This would cause a growth in population of said beetles and a possible decrease in population for animals that consume the beetles.

Explain why global climate models typically work by treating the planet as a set of connected boxes.
ivann1987 [24]

Answer:

Global climate models usually work by managing the planet as a set of connected boxes because this facilitates the management of the calculations applied in a climate system that is dynamic, variable and complex, which is due to the fact that there is not an equal pattern of climate in each area of the planet.

Explanation:

Climate models have been designed to show the dynamics of the planet's climate and what can be expected from the changes that occur in the future.

The scientific basis of a climate model is physical phenomena and chemical reactions to which a series of differential calculations are applied to determine the behaviour of:

  • <em>Winds.</em>
  • <em>Temperature.</em>
  • <em>Relative humidity.</em>
  • <em>Rainfall.</em>
  • <em>Pressure changes.</em>
  • <em>Heat transfer.</em>
  • <em>Hydrological dynamics. </em>

Global climate models usually divide the planet into sections -such as boxes- making the calculations in each sector, as well as the interaction of each section with the adjacent sections, which greatly facilitates making the differential calculations, showing the climate at a given time and making predictions of future climate behavior.

It is important to mention that a climate model also explains the changes that occur in the climate due to human activity, which is different in each region of the world.

plant and animal mitosis are very similar except for cytokinesis. explain how this process is different.
Maksim231197 [3]

Answer:

Cell division or cytokinesis in mitosis or meiosis is very similar... There is a region of division to separate the two daughter cells in both processes; however, the division plate is slightly different between animal cells and plant cells. In animals, the region of division is a division plate. hope this helps! :)

Imagine you are studying seafloor spreading along two different oceanic ridges answer
Sonja [21]
Sea floor spreading occurs at divergent plate boundaries where the seafloor is being pulled apart by convection currents in the mantle. As the plate pull apart magma up wells and new crust is being formed. This process on the sea floor creates a habitat for exotic sea creatures such as tube worms. The food chain in this region of the planet starts with bacteria that metabolizes sulfur coming from hydro-thermal vents along the spreading ridge. <span />
