The atmospheric pressure drops so the partial pressure of O2 drops proportionately. The hemoglobin must circulate faster to deliver the same quantity of oxygen to working muscles' mitochondria for cellular respiration. This increased basal circulation rate places a greater demand for oxygen to support it, which triggers in increase in red blood cell population so there is more hemoglobin to deliver O2. With more RBCs the circulation rate once more slows to the old basal rate.
Because carbon dioxide is a GREENHOUSE GAS, it can trap the sun's heat in the atmosphere. Because the factory is made of concrete, it may deplete groundwater levels over time by not allowing water to INFILTRATE.
Greenhouse gases (GHGs) are gaseous components that absorb the infrared radiation emitted by the earth's surface and contribute to the greenhouse effect. The increase in their concentration in the Earth's atmosphere is one of the factors causing global warming.
Concrete does not allow water from the ground surface to infiltrate to underground.
Answer:
Explanation:
Based on this information it can be said that this formation between the islands and the mainlands will most likely cause an increase in gene flow between the bird populations. Since the islands and the mainland are now connected birds from both these two different habitats will begin mating and producing progeny, thus causing gene flow to increase between these species.
Answer:
The correct answer is - 1. true, 2. true, 3. false, and 4. true.
Explanation:
1. Rod cells are the photoreceptors present in the retina that are hyperpolarized not depolarized in dark due to sodium ions efflux.
2. Depolarisation of the bipolar cell of the retina by glutamate release by rods and cones.
3. The adaption according to the light is known as a light adaptation which takes place due to a large part of photochemical in both rods and cones which is reduced to retinal and opsins.
4. when the light reaction takes place retinal converted to opsin
Answer:
<em>The correct option is B) Her title is accurate because one extreme is favored.</em>
Explanation:
In ecological studies, directional selection can be described as a selection due to which an extreme phenotype is favoured by natural selection and evolution causes the change in allele frequencies in favour of the extreme phenotype.
In the condition described in the question, the phenotype for eating insects was the extreme phenotype which was favoured by natural selection. The allele frequency for this extreme phenotype became abundant due to evolution. Hence, option B is correct.
