Answer:

A glance at the night sky above Earth shows that some stars are much brighter than others. ... Astronomers define star brightness in terms of apparent magnitude — how bright the star appears from Earth — and absolute magnitude — how bright the star appears at a standard distance of 32.6 light-years, or 10 parsecs.

Sergio039 [100]

Answer:

Cloning may be defined as the process by which the genetically identified individual of the organism can be created artifically or naturally. Aseual reproduction results in the formation of clone.

The microsatellite analysis is used to prove that snuppy is a clone. Microsatellites are the highly variable DNA sequences repeats that has variable loci and considered at population level. The two alleles are possible for the one microsatellite locus. After comparing the alleles it has been found that snuppy has exactly the same genetic material as the surrogate mother, afghan. This completely determines that snuppy is a clone of afgan.

the graph shows how the rate of photosynthesis of a plant varies with light intensity. interpret the graph and justify statement
dezoksy [38]

The graph shows that the rate of photosynthesis increases with increased light intensity, other conditions being constant.

<h3>Photosynthesis and light intensity</h3>

From the graph, the rate of photosynthesis increases with an increase in light intensity.

At low light intensity, the photosynthesis rate increases with an increase in the concentration of carbon dioxide and level off at some point.

With medium light intensity, the rate of photosynthesis is about twice that of low light intensity under the same concentration of carbon dioxide. It also gradually levels off when the concentration of carbon dioxide reached a particular point.

The same trend applies to high light intensity. The rate of photosynthesis increased accordingly, much more than low and medium-intensity light.

Both light and carbon dioxide concentration can limit the rate of photosynthesis. When both factors are abundant, photosynthesis can be limited by other factors such as water, nutrient, etc.
