17. To produce the same intensity and color of light, you can choose from a 60-watt incandescent bulb, a 17-watt compact fluorescent bulb, or a 10 watt LED bulbWhich is the most energy efficient?
a. The incandescent bulb.
b. The compact fluorescent FL) bulb.
c. The LED bulb
Answer:
10 watt LED bulb.
Explanation:
The most energy efficient is 10 watt LED bulb because it produces more light by consuming less amount of energy. If a substance is more efficient so it consumes less amount of energy for doing its work while on the other hand, less efficient substances uses high amount of energy for doing its work so that's why we can say that 10 watt LED bulb is more efficient its as compared to incandescent bulb and a 17-watt compact fluorescent bulb which uses high amount of energy.

In a moth population, 47 are brown, 15 are yellow, and 34 are black. What is the approximate probability of a moth being black?
A. 2%
B. 49%
C. 16%
D. 35%
Answer:
D
Explanation:
34/96= 35%
The mathematical rule of three can be used to take probabilities. In the exposed example, the approximate probability of a moth being black is 35% (Option D).
------------------------
Available data:
47 moths are brown15 moths are yellow34 moths are blackThe total number of individuals in this population equals the addition of brown, yellow, and black individuals.
This total number of individuals equals 100% of the population.
So to get the probability of a moth being black, we can just perform a rule of three.
To do it, we need to get the percentage of black individuals in the current population.
96 moths ------------------------- 100% population
34 black moths ----------------- X= (34 x 100) / 96
=35.41 ≅ 35% of the population
The approximate probability of a moth being black is 35%.

Para un carácter existen tres alelos distintos: dos codominantes entre sí y otro recesivo. ¿Cuántos genotipos distintos existirán para ese carácter?¿Cuántos fenotipos?
Answer:
6 genotipos y 4 fenotipos
Explanation:
La codominancia es un tipo de interacción alélica donde ninguno de los dos alelos puede enmascarar la expresión del otro alelo, produciendo de este modo un fenotipo diferente en presencia de ambos alelos (es decir en individuos heterocigotas). Un ejemplo de alelos codominantes son los alelos A y B del grupo sanguíneo, los cuales se expresan en individuos heterocigotos. Por otra parte, un alelo recesivo sólo puede expresarse en individuos homocigotas que portan dos copias del mismo alelo recesivo. El caso del grupo sanguíneo es idéntico a la pregunta planteada, ya que en este caso tenemos dos alelos codominantes entre sí (alelos A y B) los cuales son dominantes respecto al alelo O recesivo. En este caso, de la combinación de alelos pueden resultar seis genotipos (IAi; IAIA; IBi; IBIB; ii; AB) y cuatro fenotipos (tipo de sangre A, tipo de sangre B, tipo de sangre AB y tipo de sangre O).
Sample 2 was taken from a nasal swab of a family member who has been having sinus infections. What course of antibiotics would you recommend?
Answer:
Amoxicillin
Explanation:
Amoxicillin (Amoxil) is a commonly prescribed antibiotic which can cure acute sinus infections. Amoxicillin-clavulanate (Augmentin) is often prescribed by the doctor for a bacterial sinus infection. Take antibiotics as long as your doctor has prescribed in order to get rid completely from the infection and in order to reduce the chances of infection up to zero. They may be taken from 3 to 28 days depending on the time of antibiotic for sinus infection.

Which type of growth can occur only when a population has unlimited resources?
limited
logistic
exponential
negative
Answer:
c. on edge
Explanation:
When resources are unlimited, populations exhibit exponential growth, resulting in a J-shaped curve. The correct answer is c) exponential.
What is the exponential growth curve?Exponential growth curves and logarithmic growth curves are the two different forms of growth curves. In an exponential growth curve, the slope increases steadily over time. A logarithmic growth curve has a steeply increasing slope that gradually flattens out over time.
The exponential growth curve, which has a J-shape, shows a period of time where the results develop rapidly and steadily. It is the reverse of gradual progress. This curve initially climbs gradually before accelerating, which represents multiplied growth.
With exponential growth, a population's growth rate per capita (per person) remains constant regardless of population size, causing the population to expand exponentially as it grows larger. In nature, populations may expand exponentially for a while, but ultimately, their growth will be constrained by the availability of resources.
Exponential expansion happens when resources are unrestricted. Due to the favorable conditions, there are a lot more births as a result of the food excess.
Therefore, the correct answer is c).
