HELP 80 POINTS IF U ANSWER + BRAINLIST!!!

Biology
1 answer:
kumpel [21]2 years ago
8 0

Answer:

Once exposed, they are weathered, both physically (by mechanical breaking of the rock) and chemically (by weathering of the minerals), and the weathering products — mostly small rock and mineral fragments — are eroded, transported, and then deposited as sediments. Therefore, the model should show signs of deterioration and subduction.

Explanation:

I'm not sure if this is on a quiz or test, but this is what I would put down. No need to mark me brainliest, thanks anyway! :)

¿Qué efecto tiene para las cadenas tróficas la tala y deforestación de los organismos productores?
Morgarella [4.7K]

Answer:

tiene un efecto devastador sobre las cadena tróficas de ecosistemas terrestres

Explanation:

En una cadena trófica, los organismos productores, también conocidos como autótrofos, son aquellos capaces de convertir la energía proveniente del Sol (organismos fotosintéticos) o de la oxidaxión de compuestos inorgánicos (organismos quimiosintéticos) en nutrientes a través de la formación de enlaces de carbono que componen moléculas orgánicas tales como, por ejemplo, carbohidratos (es decir, celulosa, azúcar, etc). Por ejemplo, los árboles son organismos productores que usan la fotosíntesis para convertir la energía lumínica solar en energía química la cual es utlilizada por consumidores primarios (hervívoros) de la cadena trófica. Los árboles son organismos productores los cuales juegan un papel clave en ecosistemas terrestres, representando la principal fuente de alimento y nutrientes para diferentes consumidores primarios. Además, estos organismos autótrofos son también fundamentales porque generan oxígeno (O2) y capturan el dióxido de carbono (CO2) de la atmósfera, lo cual es un proceso clave para el sostenimiento de la vida en la tierra.

Waters ____ makes it excellent solvent for salts like sodium chloride as well as other substances required by cells to carry out
valentinak56 [21]

The right answer is polarity.

In chemistry, polarity is a characteristic describing the distribution of negative and positive charges in a dipole. The polarity of a bond or a molecule is due to the difference in electronegativity between the chemical elements that compose it, the differences in charge that it induces, and to their distribution in space. The more the charges are distributed asymmetrically, the more a bond or molecule will be polar, and conversely, if the charges are distributed in a completely symmetrical manner, it will be apolar, that is to say non-polar.

Polarity and its consequences (van der Waals forces, hydrogen bonding) affect a number of physical characteristics (surface tension, melting point, boiling point, solubility) or chemical (reactivity).

Many very common molecules are polar, such as sucrose, a common form of sugar. The sugars, in general, have many oxygen-hydrogen bonds (hydroxyl group -OH) and are generally very polar. Water is another example of a polar molecule, which allows polar molecules to be generally soluble in water. Two polar substances are very soluble between them as well as between two apolar molecules thanks to Van der Waals interactions.
