Irina's claim is not found here but evidence from an experiment might include the amount of a product (chemical) or the order of nucleotides (biological evidence).
<h3>What is scientific evidence?</h3>
Scientific evidence refers to the observations that can be used to support (or reject) a working hypothesis.
Scientific evidence is variable depending on the field but it is always collected by observational or experimental procedures.
In conclusion, Irina's claim is not found here but evidence from an experiment might include the amount of a product (chemical evidence) or the order of nucleotides (biological evidence).

Answer:
Small external openings of lungs help in two ways:
1. It helps in trapping the dust and pathogens like bacteria, fungal spores et cetera. Larger opening would provide dust and pathogen a wider area to enter into the body.
2. The smaller opening prevents the drying of the respiratory membrane. A moist membrane is essential for the successful exchange of oxygen and carbon dioxide in the lungs.
In the dark, an object is more clearly seen when viewed in peripheral vision than when viewed directly, this phenomenon occurs because the rods located in the retina are:<u> more </u><u>sensitive</u><u> in the dark than </u><u>cones</u>.
The retina extends through the posterior portion of the eyeball is the innermost layer and in it are the photoreceptors: cones and rods.
Rods and cones are the two types of photoreceptor cells in vertebrates that capture light energy (photons) and convert it into electrical signals.
- The rods are sensitive to changes in light, since their detection thresholds are low, so they only come into operation when the light intensity is low (scotopic vision or night vision).
- Scotopic vision has relatively low acuity, as the details of an object cannot be discerned or its color appreciated.
- On the contrary, cones have a much higher threshold for light, they are responsible for daytime vision (photopic vision) and their mission is to detect colors and shapes (details).
Therefore, we can conclude that in the dark, an object is more clearly seen when viewed in peripheral vision than when viewed directly, this phenomenon occurs because the rods located in the retina are: more sensitive in the dark.

Answer:
if the lacI gene, in the genetically engineered fluorescent strain were non-mutant but the lacO sequence on the chromosome is mutated to lacOc then,
in the presence of the inducer, the cells fluorescence will show
yellow; red
in the absence of inducer, the cells fluorescence will show,
yellow; no fluorescence.
Explanation:
when lacO is mutated with lacOc then constitutive mutation happens which lets the system to be on.
The formula for speed is: v=x/t, where v is speed, x is distance, and t is time.
v=27/9
v=3
B) 3 m/s
Hope this helps!!
