Solución: El problema indica que se le están suministrando 700 calorías de calor, eso quiere decir que Delta Q será positivo, por otra parte nos dice que al sistema se le aplicará un trabajo de 900 Joules, aquí el signo de Delta W tendrá que ser negativo, puesto que se la están aplicando al sistema.
Sabiendo ese análisis podemos dar solución al problema de la siguiente forma:
Answer:
Destruction of animals' habitats. Some examples of this are... tree logging, slash and burn farming, and deforestation. Humans also hunt animals to extinction either for sport or food.
Explanation:
Answer:
1) RR x rr
2) Shown below
3) 100% Rr with red eyes
4) Punnett square shown (Rr x Rr)
5) 25% of the offspring are h0m0zygous dominant with red eyes (RR), 50% are heterozygous with red eyes (Rr), and 25% are h0m0zygous with brown eyes (rr)
Explanation:
Let's say the allele for red eyes is R and the allele for brown eyes is r.
1. A cross between a h0m0zygous dominant (two copies of the dominant allele, R) and h0m0zygous recessive (two copies of the recessive allele, r) is: RR x rr
2. R R
r <em>Rr Rr</em>
r <em>Rr Rr</em>
<em />
The F1 generation is shown in the Punnett square above.
3. The F1 generation are 100% Rr. They are heterozygous. Since red (R) is dominant, the rats all have red eyes
4. A cross between the F1 generation (Rr x Rr) gives the F2 generation
R r
R <em>RR Rr</em>
r <em>Rr rr</em>
<em />
5. 25% of the offspring are h0m0zygous dominant with red eyes (RR), 50% are heterozygous with red eyes (Rr), and 25% are h0m0zygous with brown eyes (rr)
