Lyra  Latin for lyre, from Greek  is a small constellation. It is one of 48 listed by the 2nd century astronomer Ptolemy, and is one of the 88 constellations recognized by the International Astronomical Union. Lyra was often represented on star maps as a vulture or an eagle carrying a lyre, and hence sometimes referred to as Aquila Cadens or Vultur Cadens. Beginning at the north, Lyra is bordered by Draco, Hercules, Vulpecula, and Cygnus. Lyra is visible from the northern hemisphere from spring through autumn, and nearly overhead, in temperate latitudes, during the summer months. From the southern hemisphere, it is visible low in the northern sky during the winter months.

Vega, Lyra's brightest star is one of the brightest stars in the night sky, and forms a corner of the famed Summer Triangle asterism. Beta Lyrae is the prototype of a class of stars known as Beta Lyrae variables. These binary stars are so close to each other that they become egg-shaped and material flows from one to the other. Epsilon Lyrae, known informally as the Double Double, is a complex multiple star system. Lyra also hosts the Ring Nebula, the second-discovered and best-known planetary nebula.

Which of the following could be done to help reduce global warming trends?
timama [110]

Answer: A. Plant more trees

Explanation: Planting more trees can reduce more pollution that is in the air.

B is wrong because by bottling up more water, it requires more plastic that may be littered on the ground. Raising more livestock is helps the environment through their feces, but it doesn't help global warming trends. Building more schools does not even reduce global warming trends at all. It may do more damage if machines that produces pollution are used during the process of building.

Hope this helps!!!

Provide an example of how cells balance the redox potential between different cellular components?
crimeas [40]

En la respiración celular, la célula depende totalmente de las reacciones Redox, para ser precisos de la reducción del NAD a NADH y la oxidación de NADH a NAD.

Ahora veamos una situación diferente.

En la fotosíntesis, ocurre la reacción inversa de redox, como se muestra en la siguiente ecuación:

6CO2 + 6H2O + E --> C6H12O6 + 6O2

La energía biológica se almacena y se lanza con la frecuencia por medio de reacciones redox. La fotosíntesis implica la reducción del CO2 en azucares y la oxidación del H2O en oxigeno molecular (O2), mientras que en la respiración es lo inverso, la oxidación de azucares a CO2 y H2O.

Entre los pasos redox de la fotosíntesis, compuestos deducidos del CO2 reducen el NAD lo que crea entonces, la creación gradiente de protones, que conduce a la síntesis del ATP y es mantenida por la oxidación del O2.

En los seres vivos, el término redox se utiliza para describir el equilibrio NAD-NADH y NADP-NADPH.

El estado redox contribuye al equilibrio de los sistemas metabólicos. En el caso de alteraciones en las reacciones redox, puede producirse HIPOXIA, que es el déficit del O2 en la sangre, CHOQUE, que es el mal circulamiento de lal sangre y la SEPSIS.

While Maria's mom has small ears (alleles ee), her dad has large ears (alleles EE). What are the possible phenotypes Maria would
Svetach [21]
The only possible phenotype is large ears.

This is because using a punnet square reveals that each option has a dominant allele of large ears, leaving no room for the recessive trait of small ears.

Hope this helps!
