Answer:

Energy is transferred from the sun to Earth via electromagnetic waves, or radiation. The heat you feel in your body is the suns energy entering your body from the energy transfers that happen when you move.

Explanation:

Most of the energy that passes through the upper atmosphere and reaches Earth's surface is in two forms, visible and infrared light. The heat you feel in your body results from the energy transfers that happen when you move. When you sweat, your body expends energy to cool itself down. A food chain shows how energy flows from one organism to another. In general, energy flows from the Sun to producers and then to consumers.

A colleague gives you two tubes containing membrane fractions from an animal cell lysate. One tube contains the plasma membrane

OLga [1]

Answer:

B) a higher protein to lipid ratio.

Explanation:

The cell membrane of eukaryotes is known to be a phospholipid bilayer with embedded proteins. This implies that the first tube will contain a higher amount of lipids.

The membrane of the mitochondria is slightly different from the cell membrane in which its protein to lipid ratio is higher, containing a large number of integral proteins.

The term ____________________ means the lack of muscle coordination during voluntary movement.

tia_tia [17]

The term Ataxia means the lack of muscle coordination during voluntary movement.

Poor muscle control that results in awkward voluntary movements is known as ataxia.
It might make it difficult to move your eyes, speak, or walk steadily. It might also make it hard to coordinate your hands.
Ataxia is typically caused by injury to the cerebellum, which regulates muscular coordination, or its connections.
Ataxia is typically brought on by damage to the cerebellum, a region of the brain, although it can also be brought on by injury to the spinal cord or other nerves.
The spinal cord, which extends the length of the spine and connects the brain to every other part of the body, is a lengthy bundle of nerves.

You are performing a biochemical purification of enzymes involved in DNA replication. You have purified the replisome. You wish

algol [13]

Confirm that the sample has both helicase and primase activities, but not the ability to synthesize DNA

The replisome is a multiprotein-RNA complex that is required for the replication of DNA. The replisome consists of different proteins which include:

1. Helicase enzymes that unwind and separate the DNA strand

2. Replication factor C (RFC), a DNA-dependent ATP that acts as an activator of DNA polymerase.

3. Proliferating cell nuclear antigen (PCNA)

4. DNA gyrase/topoisomerase that cuts and reseals DNA strands, which is essential for DNA synthesis.

5. Primase enzyme that synthesizes short RNA fragments called primers.

6. DNA polymerase III, an enzyme that catalyzes the polymerization of deoxyribonucleotides into a DNA strand.

7. DNA ligases enzymes that form phosphodiester bonds at a single-strand break in DNA

A primosome is a multiprotein complex responsible for creating RNA primers on single-stranded DNA (ssDNA) during the replication process.

The primosome is composed of different primase and helicase enzymes. In Escherichia coli, it consists of PriA helicase, PriB, PriC, DnaB helicase, DnaG (encoded by the dnaG gene), DnaC and DnaT primase.

Una solución de 0.204 M de NaOH seutiliza para neutralizar 50 mL de una solución de H3PO4. Si se necesitaron 16.4 mL de la soluc

vfiekz [6]

Answer: 0.05 M

Explanation:

Para responder esta pregunta, hay que tener en cuenta la Ley de Conservación de la Masa. La misma indica que en una reacción química en un sistema cerrado, la masa total de las moléculas que participan permanece constante. Esto significa que la masa utilizada en los reactivos es la misma que la masa de los productos generados.

En este problema, se cuenta con una solución de NaOH (hidróxido de sodio) tiene una molaridad de 0.204 (siendo la molaridad el número de moles por litro de solución) y se utilizan 16.4 mL de dicha solución para agregarla a 50 mL de una solución de H3PO4 (ácido fosfórico).

Entonces, ya que la masa de ambas soluciones no se pierde, podemos utilizar la ecuación de la Ley de Conservación de la Masa:

Concentración inicial x Volumen inicial = Concentración final x Volumen final.

Concentración inicial: 0.204 M

Volumen inicial: 16.4 mL

Concentración final: ?

Volumen final: 50 mL + 16.4 mL = 66.4 mL

Reemplazamos los valores en la ecuación:

0.204 M x 16.4 mL = Concentración final x 66.4 mL

La molaridad de la solución de H3PO4 es de 0.05 M.
