Answer:

 Fruit (pods or hulls etc) bearing seeds are a means of dispersal for plants because they are sessile and have no means to move once germination anchors them with roots. Seeds are the dormant propagules or the quiescent, dispersing agents of the next generation that travel away from the parent plant  in a disposal. This is why fruit/seeds are categorized by their dispersal by wind (hydrochoric) or by animals (zoochoric).

How do materials move within the earth.
statuscvo [17]

The new materials from the center of the Earth rises, so the hardens and pushes older pieces of the Earth away from each other, which causes the movement of materials.

<h3>How do materials move within the earth?</h3>

The Earth's thermal energy is the main cause of the movement of materials within the earth surface. The Large continent-size plates moves slowly about the Earth's surface, which is driven by the thermal energy. The Convection currents transfer hot, buoyant magma to the lithosphere's layer at plate boundaries and hot spots. Convection currents also transfer denser, cooler material from the crust to Earth's interior through the process of subduction.

So we can conclude that: The new materials from the center of the Earth rises, so the hardens and pushes older pieces of the Earth away from each other, which causes the movement of materials.

¿Qué se puede agregar a un átomo para hacer que un electrón sin valencia en el átomo se convierta temporalmente en un electrón d
NNADVOKAT [17]

Energía.

Explicación:

Generalmente, los electrones giran continuamente en las capas de los átomos. Si estos electrones se encuentran en las capas más externas de un átomo, se denominan electrones de valencia.

Son necesarios para las reacciones químicas de un átomo en particular con otro, a través de sus pérdidas o compartidas.

En los átomos sin valencia, sus capas más externas no tienen electrones en sus capas más externas, tales átomos son estables.

Sin embargo, si se suministra cierta cantidad de energía a dicho átomo, el electrón gana energía y, por lo tanto, se excita.

Por lo tanto, se mueven de niveles de energía más bajos a niveles de energía más altos, y hacen que el átomo sin valencia se convierta en valencia temporalmente, a medida que se mueven hacia la capa más externa.

Answer:

Energy.

Explanation:

Generally, electrons revolves continuously in the shells of  atoms.if these electrons are located in the outer most shells of an atom,they are refereed to as the Valence electrons.

They are needed for chemical reactions of a particular atom with another,through their loses or sharing.

In Non -valence atoms their outermost shells do not have electrons at their outermost shells,such atoms are stable.

However, if  certain quantity of energy is supplied  to  such atom, the electron  gains energy and therefore becomes excited.

They therefore move from lower energy levels to higher energy levels,and makes the non- valence atom becomes valence temporarily, as they move into the outermost shell.

Atrazine is an herbicide that prevents plant growth by inhibiting photosynthesis. Atrazine works by binding to proteins in the e
Sauron [17]

It prevents the formation of ATP and NADPH, which are needed by the light-independent reactions to make sugars. Thus, the correct option is D.

The herbicide atrazine binds to the D1 protein and prevents plastoquinone from binding. By preventing plastoquinone from binding, the photosynthetic transport of electron is disrupted, putting the generation of ATP and NADPH in the chloroplast at risk.

 

<h3>What are herbicide?</h3>

Herbicides are chemicals that are used to control or manage unwanted vegetation. Herbicides are most commonly used in row-crop farming, where they are treated before or during planting to increase crop productivity while reducing other vegetation.

This results in the plant's inability to fix carbon dioxide and provide the nutrients it needs to survive. A halt in electron transmission causes oxidative stress and the generation of radicals, which leads to rapid cellular death.

What make up lipids..?
Sav [38]
Lipids are made up of carbon, hydrogen, and oxygen. So I'm assuming A would be the best answer. Proteins are made up of carbon, hydrogen, oxygen, and nitrogen and nucleic acids are made up of carbon, hydrogen, oxygen, nitrogen, and phosphorus.
