Answer:
Breed "pure" mice with known genotypes that exhibit specific fur and eye colors, and learn how traits are passed on via dominant and recessive genes. Mice can be stored in cages for future breeding, and the statistics of fur and eye color are reported every time a pair of mice breed.
Explanation:
Answer:
PP = 25%
Pp = 50%
pp = 25%
Explanation:
Using punnett square, we can predict the percentage probability of genotypes.
P p
P PP Pp
p Pp pp
In this cross we have,
PP = 1/4 = 25%
Pp = 2/4 = 50%
pp = 1/4 = 25%
We have ratio,
1 : 2 : 1
Answer:
El árbol de la vida o árbol universal de la vida es una metáfora, modelo y herramienta de investigación que se utiliza para explorar la evolución de la vida y describir las relaciones entre organismos, tanto vivos como extintos, como se describe en un famoso pasaje de El origen de las especies (1859) de Charles Darwin.2
Explanation:
Wind power:
Advantages:
-Using wind as a source of power is very cost-effective. This is method is fuel free and the electricity harvested from wind farms is sold at a fixed price over a long period of time.
-Wind power is a clean fuel source. Using wind as a source of power prevents air pollution unlike power plants that mostly rely on fossil fuels which releases toxins into the hair causing both environmental and health problems.
-Wind power is a sustainable source of power since nothing can really stop it from being produced. Since this source of power relies on air, as long as there is air, energy can be harvested.
Disadvantages:
-Wind turbines are usually built in rural areas due to the size of them and the amount of space needed to build them. Because of this, they aren’t usually close to cities or remote locations where the energy harvested from them is most needed.
-Wind turbines can harmfully impact nature. Because of their height and size, many birds and other flying animals end up getting killed by the spinning blades connected to the turbine.
-Locations to build wind turbines may be hard to get due to competition with other things that may be of more importance on the land compared to wind farms.
