<h3><u>Answer;</u></h3>
Label A; Mitochondria.
Label B; Nucleus.
Label C; Golgi apparatus.
Label D; Rough endoplasmic reticulum
<h3><u>Explanation;</u></h3>
- All the above are various organelles in a eukaryotic cells each carrying different cellular activity to enhance the functioning of a cell.
Label A; Mitochondria.
- <u>Mitochondria</u> is the powerhouse of the cell which converts glucose to energy rich molecules of ATP, through the process of cellular respiration.
Label B; Nucleus.
- <u>Nucleus</u> contains the genetic material or DNA, RNA , nucleolus, chromatin fibres and proteins. It contains the chromosomes which control the hereditary characteristics.It also regulates all the activities of the cell.
Label C; Golgi apparatus.
- <u>Golgi apparatus;</u> they are also called Golgi bodies. They function in modifying, sorting and packaging of proteins for secretion. They are also involved in the transport of lipids around the cell, and the creation of lysosomes.
Label D; Rough endoplasmic reticulum
- <u>The rough endoplasmic reticulum</u> provides surface for protein synthesis. It is also used to transport cellular contents from one cell to another.
- The risbosomes attached on the rough endoplasmic reticulum are resposible for the protein synthesis through the process of translation.
Answer:
A) Falso, cuando un resorte se estira, este comienza a acumular energía potencial. Al soltar el resorte, este tratara de volver a su forma natural, consumiendo la energía potencial y transformándola en energía cinética.
B) Falso. Potencia esta definido como la cantidad de trabajo efectuado por unidad de tiempo, a mayor potencia, mas rápido se completa un trabajo.
C) Verdadero, el trabajo es escalar, pues resulta de un producto punto entre dos vectores, la fuerza y el desplazamiento.
D) Falso, el cambio en la energía cinética de un cuerpo es igual al trabajo neto aplicado sobre ese cuerpo. Es decir, si le aplico trabajo a un cuerpo, estoy cambiando su energía cinética.
E) Falso, la fuerza del vagón sobre los pasajeros NO es constate, ya que esta fuerza esta relacionada con la velocidad a la que se mueve el vagón, y sabemos que la velocidad del vagón va cambiado durante el trayecto (podemos experimentar esta fuerza al pasar de una horizontal a una pendiente muy pronunciada, ya que hay un gran cambio de velocidad, y si hay cambio de velocidad, hay aceleración, y por la tercera ley de Newton, si hay aceleración, hay fuerza), pero si es verdad que esta fuerza es un factor importante al diseñar una montaña rusa.
The type of proteins that can function as the chemical messengers or as the receptors in the plasma membrane is a communication proteins; option A.
Proteins are large macromolecules composed of chains of amino acid units linked together by peptide bonds.
Proteins serve various functions such as:
communication
transport
defensive
enzyme
Communication of proteins such as the hormones can be function as the chemical messengers or as receptors in the plasma membrane.
Proteins are made up of hundreds or the thousands of the smaller units called as amino acids, which are attached to one another in the long chains. There are about 20 different types of amino acids that can be combined to make a protein.

Explanation:
pros are they look like humans maybe even talk and walk like us but do/will they act like us...
