a. Simazine is an herbicide used on corn, fruit and nut crops, and Christmas trees. This herbicide binds to the electron transpo

rt chain in the thylakoid membrane of the chloroplasts. When simazine binds to the electron transport chain, electrons are no longer able to flow through the chain. Describe all of the processes of the light reactions disrupted when Simazine is present.

Answer:the thylakoid membrane usually has two photosystems that absorbs sunlight;the photosystems 11 and 1 .in the light reaction of photosynthesis,when light energy hits the photosystems,the electrons are boosted to higher energy and pass through the electron Transport chain by electron acceptor molecules until it is used in the formation of ATP and NADPH.

However when simazine is present,electrons can no longer be transferred from one electron acceptor to the other for the reduction of NADP+ to NADPH.

Also since no electron is being transferred,the PS II would not have a need to split water molecules ,which products are more electrons and protons which pass through the thylakoid lumen and creates a proton gradient needed for the production of ATP

Explain the nuclear model of the atom
EastWind [94]

Answer:

Explanation:

The nuclear model of the atom was suggested by Ernest Rutherford based on his experiment on a thin gold foil.

To explain his observations, he suggested the atomic or nuclear model.

In this model, the atom has a small positively charged center called the nucleus.

All the mass of the atom is concentrated here in the nucleus.

Surrounding the nucleus is a large space

It is the extranuclear part

This part contains electrons.

A nucleus surrounded by electrons forms the nuclear model of the atom.

A sample of a solid nonmetal is compared to a sample of a solid metal. Both samples have the same volume. What is the
EleoNora [17]

Answer:

STRUCTURE:

  • Metals have a crystalline structure, whereas non-metals possess amorphic structure.
  • At room temperature, metals are usually solid, except mercury and gallium which are in the liquid state. Conversely, non-metals can be found in solid or gaseous form, except Bromine which is the only non-metal that is present in liquid form.
  • Density is the ratio of mass to volume; metals have a higher density as compared to non-metals.
  • Metals look smooth and shiny, while non-metals usually appear dull.
  • When it comes to hardness, metals are generally hard substance, but it varies from substance to substance. Unlike non-metals is soft substance except diamond, which is the hardest substance on earth.

CHEMICAL PROPERTIES:

  • Metals support conduction of heat and electricity. Conversely, non-metals are insulators, and so they do not support conduction of heat and electricity.
  • Metals have a very high melting and boiling point. In contrast, non-metals are boiled and melted at a relatively low temperature.
  • In the outer shell, metals consist of 1 to 3 electrons, whereas non-metals consist of 4 to 8 electrons.
