Answer: Stomata
Explanation:
Stomata are pores in the leaf that allow gas exchange where water vapor leaves the plant and carbon dioxide enters.
A symbiotic relationship in which one organism can take
advantage and the other is not harmed The treehopper-ant mutualism becomes
parasitic in years when spiders are rare, because the treehoppers no longer
derive a large benefit but pay a fitness cost.
Answer:
The correct answer is -50%
Explanation:
Polydactyly is a dominant trait where a person gets an extra finger or toes the dominant allele is represented by P = allele for polydactyly, and the recessive allele represented by p = normal allele
So, the heterozygous woman will be - Pp & the normal man will be - pp. The presence of one allele of polydactyly will be able to show its effect as it is dominant.
Cross between heterozygous woman & normal man:
Gametes:
P p
p Pp (Show polydactyly) pp (Normal phenotype)
p Pp (Show polydactyly) pp (Normal phenotype)
From the above Punnett square, the probability of an offspring that has extra fingers or toes will be 1/2 or 50%.
The conditions which describe the partial pressures of systemic cells under resting conditions are:
- Relatively constant partial pressure of gases
- PCO₂ of 45mm Hg, and
- PO₂ of 40mm Hg
<h3>What are systemic cells?</h3>
Systemic cells are cells of the body which receive oxygen from the capillaries during respiration and gaseous exchange.
The systemic cells receive oxygen-laden blood from the capillaries and transfer carbon dioxide into the blood capillaries.
The conditions which describe the partial pressures of gases of systemic cells under resting conditions are as follows:
- Relatively constant partial pressure of gases
- Partial pressure of carbon dioxide, PCO₂ of 45mm Hg, and
- Partial pressure of oxygen, PO₂ of 40mm Hg
In conclusion, the partial pressure of the gases in systemic cells under resting conditions are fairly constant.
