How might an athlete use vital lung capacity compared to a non athlete

Biology
1 answer:
kramer3 years ago
5 0
An athlete would have a larger vital capacity than a non-athlete aerobic ability would find people with larger lungs and hence a bigger vital capacity. The vital capacity of an athlete is higher than a non-athlete because they are trying to do hard work their legs to get bigger and bigger over time making it easier for them

Photosynthesis requires a supply of CO2 as well as H2 O and sunlight. How do plants obtain these resources? (Hint: refer to plan
Triss [41]

Answer:

CO2 is supplied by mammals and other living animals exhaling, producing CO2 this is absorbed through their leaves, and stems

H2O is supplied by the water cycle, nearby rivers, oceans, creeks etc. This is soaked up through their roots. Excess sugars are also stored in the roots as food.

Sunlight is provided in the atmosphere and the chlorophyll absorbs this.

In the fruit fly Drosophila, there is a dominant gene for normal wings and its recessive allele for vestigial wings. At another
aev [14]

Answer:

15

Explanation:

The genes for vestigial wings (vg) and purple eyes (pr) are linked on the same chromosome.

<u>The following cross was made:</u>

Heterozygous male for both genes   X female<em> vg pr / vg pr</em>  

The male could be either <em>vg+pr+/vg pr</em> or<em> vg+ pr/vg pr+</em>.

The female only produces <em>vg pr </em>gametes.

<u>The following offspring was observed: </u>

420 Normal wings and red eyes (<em>vg+ pr+/vg pr</em>)

430 Vestigial wings and purple eyes (<em>vg pr / vg pr</em>)

80 Vestigial wings and red eyes (<em>vg pr+ / vg pr</em>)

70 Normal wings and purple eyes (<em>vg+ pr / vg pr</em>)

Total: 1000

The individuals observed in the highest frequency have the parental genotypes. The recombinant individuals are <em>vg pr+ / vg pr</em> and <em>vg+ pr / vg pr.</em>

Distance = Number of recombinants × 100 / Total

Distance = (80 + 70)×100 /  1000

Distance = 15 cM.

<em>Just a small note, male drosophila do not experience crossing over in meiosis, so there would be no recombinants observed from this cross. The problem is probably mixed up, the female should be heterozygous and the male the homozygous recessive.</em>
