A 12 pound shot put and a small metal BB are dropped from a tall tower, inside a vacuum chamber,
hichkok12 [17]

Given what we know, we should observe the objects falling at the same speed in both the tower and vacuum scenarios, but not in the water.

<h3>What affects the speeds at which these objects fall?</h3>
  • The falling speeds in both air and a vacuum will be the same for both objects.
  • This is because falling speed is determined by gravity and is independent of the mass of the objects falling.
  • The same will occur in water if and only if the densities of the two objects are equal.

Therefore, given that we can safely assume that the densities of the two objects are different from one another, we can confirm that while the objects will fall at the same speed in air and in a vacuum, this will not be the case in the deep pool.

A cell with 30% solute is in an environment that consists of 25% solute. Which statement is true?
faust18 [17]

Answer:

Hypotonic solutions are those with less solute (again read as higher water potential). Isotonic solutions have equal (iso-) concentrations of substances. Water potentials are thus equal, although there will still be equal amounts of water movement in and out of the cell, the net flow is zero.

Chemical triggers and messengers for many
ale4655 [162]

Answer:

Proteins

Explanation:

Proteins are macromolecules composed of amino acids that perform multiple and varied functions in the body. Proteins that act as chemical messengers are present in the form of hormones, ligands, neurotransmitters, regulatory proteins and enzymes.

Genes code for proteins that in turn control all life processes. The differences we witness in individuals such as weight, height, skin color, intelligence etc are all due to our unique genetic code and a unique combination of proteins that these genes encode. Furthermore, the levels to which our genetic code is expressed is also regulated at the molecular level by proteins.

3. Nombra las reacciones que ocurren en el paso de<br> Alfacetoglutarato a succinato
Shkiper50 [21]

Answer:

Hidrólisis y oxidación.

Explicación:

La hidrólisis y la oxidación son las reacciones que ocurren en el paso del alfacetoglutarato a succinato. En el quinto paso hay una hidrólisis del grupo tioéster de CoA en la que los átomos de los compuestos se rompen y luego sustituyen sus elementos miembros. Esta reacción de hidrólisis libera energía y se hace un ATP a partir de ADP. En el paso 6, succinato a fumarato es una oxidación para poner en el doble enlace significa que FAD se reduce a FADH2. Entonces podemos decir que la hidrólisis y la oxidación son las reacciones que ocurren en el paso de Alfacetoglutarato a succinato.
