<span>H. floresiensis tended to be smaller than H. sapiens. In addition, they had much smaller heads and, therefore, smaller brains. Also, the species had a much more sloped forehead, shoulders that were more forward-leaning, and feet that were relatively large for their small body size.</span>
I think you wrote this wrong? Is it not round rr vs wrinkled RR?? I'll answer it with that assumption:
You are crossing a rr with an RR:
You only get Rr back so they will phenotypically be all wrinkled
If you are crossing rr with an Rr (so a heterozygote wrinkled):
50% will be Rr (wrinkled)
50% will be rr (round)
See my picture for the Punnett Squares for both answers!
Answer:
Sunlight hits a smaller surface area at the Equator so heats up quickly compared to the poles. Explanation:
I believe it's B. Apologies if I'm wrong.
Answer:
d. alveolar ventilation rate
Explanation:
Alveolar Ventilation rate (AVR) refers to the rate of airflow that reaches the alveoli which is available for gas exchange with the blood in a given unit of time. AVR is generally calculated as the amount in millimeters of air expired that equilibrates (i.e., exchanges) with alveolar gas per min unit (ml/min). AVR is affected by breathing frequency, tidal volume ( i.e., the normal amount of air between inhalation and exhalation), and the amount of dead space in the lungs.
