sleet_krkn [62]

Answer:

P. aeruginosa

Explanation:

P. aeruginosa is a gram-negative bacteria that belongs to the family Pseudomonadaceae.

From the given question the following points lead us to conclude that the colony that will be growing would be of P. aeruginosa :

1. Flat spreading colonies with a metallic sheen on SBA - P. aeruginosa is known to produce smooth colonies with flat edges.

2. Fluorescent green color in the media with clear colonies on cetrimide agar - P. aeruginosa is known to produce pyoverdin which is a fluorescent pigment under low iron conditions.

3. Medium clear colonies that have a "fruity or grape-like odor" on MacConkey Agar - P. aeruginosa has a sweet fruity odor which is its characteristic odor because of the production of trimethylamine.

Thus, from all these characteristics one can conclude that the organism in the culture is P. aeruginosa.

You are at a restaurant where they offer both grass-fed and grain-fed beef, and are trying to decide which is the most sustainab

atroni [7]

Answer:

Grass-fed beef is the most sustainable choice. Grass-fed beef represents a net gain for the human food supply because cows eat grasses that we can’t eat (from land that is typically unsuitable for human crops) and turn it into beef that we can eat.

Explanation:

Cattle raised on a primarily foraged diet are termed grass-fed or pasture-raised; for example meat or milk may be called grass-fed beef or pasture-raised dairy. The term "pasture-raised" can lead to confusion with the term "free range", which does not describe exactly what the animals eat.

That said, grass-fed cows eat (mostly) grass, while grain-fed cows eat (mostly) an unnatural diet based on corn and soy during the latter part of their lives. To maximize growth, the cows are often given drugs, such as antibiotics and growth hormones.

JongHyun is able to play "Go Fish," a card game that requires quick thinking. What brain change most directly supports his abili

Allisa [31]

Answer:

Myelination.

Explanation:

Brain acts as one of the most important organ of the body that helps in receiving the stimuli and interpret the information in the form of signal. Two main types of neuron are myelinated neuron and unmyelinated neuron.

The myelinated neuron increases the conductivity of the impulse. The myelinated neurons are much more active than the unmyelinated neuron. In case of the quick thinking and instant actions, the myelinated neurons play an important role.

Thus, the answer is myelination.

Una raza de gallinas, denominada andaluza, presenta plumajes de tres colores negro, blanco y azul. El azul resulta de la combina

Anna007 [38]

Answer:

a) Genotipo: 50% = 1/2 Nn - Fenotipo: 50% = 1/2 Plumaje Azul

50% = 1/2 NN - 50% = 1/2 Plumaje Negro

b) Genotipo: 50% = 2/4 = 1/2 Nn - Fenotipo: 50% = 1/2 Plumaje Azul

25% = 1/4 NN 25% = 1/4 Plumaje Negro

25% = 1/4 nn 25% = 1/4 Plumaje Blanco

c) Genotipo: 50% = 1/2 Nn - Fenotipo: 50% = 1/2 Plumaje Azul

50% = 1/2 nn - 50% = 1/2 Plumaje Blanco

Explanation:

Datos:

Llamaremos al Gen para color del plumaje: N

Alelo dominante N para color negro

Alelo recesivo n para color blanco

Animales con genotipo homocigota para alelo dominante, NN, expresan plumaje negro

Animales con genotipo homocigota recesivo, nn, expresan plumaje blanco

Animales con genotipo heterozigota, Nn, expresan color azul.

Este es un ejemplo de dominancia incompleta, en la cual ninguno de los dos alelos domina completamente al otro. El alelo dominante, en este caso N, no puede cubrir el efecto del alelo recesivo, n. Los desendientes, entonces, poseen un fenotipo intermedio entre los dos fenotipos parentales, que en este caso es el color azul en el plumaje.

Entonces:

a) Plumaje azul x plumaje negro.

Parental) Nn x NN

Gametas) N n N N

Cuadrado de Punnet) N n

N NN Nn

F1) 1/2 de la progenie es homocigota dominante, NN, color negro

1/2 de la progenie es heterocigota, Nn, con plumaje color azul

b) Plumaje azul x plumaje azul.

Parental) Nn x Nn

Gametas) N n N n

Cuadrado de Punnet) N n

N NN Nn

n Nn nn

F1) 1/4 de la progenie es homocigota dominante, NN, color negro

2/4=1/2 de la progenie es heterocigota, Nn, con plumaje color azul

1/4 de la progenie es homocigota recesivo, nn, con plumaje blanco

c) Plumaje azul x plumaje blanco

Parental) Nn x nn

Gametas) N n n n

Cuadrado de Punnet) N n

n Nn nn

F1) 1/2 de la progenie es homocigota recesivo, nn, color blanco

1/2 de la progenie es heterocigota, Nn, con plumaje color azul
