Although fictional, a martian, in this sense, would be considered living. While a car would be considered non living.
Hope this helps :)
 
        
             
        
        
        
Answer:
100%
Explanation:
This question involves two genes in guinea pigs; one coding for fur color and the other for fur length. The alleles of black fur (B) and short fur (F) is dominant over the alleles for brown fur (b) and long fur (f). 
In a cross between two offsprings with genotypes: BBFF x bbff, the following gametes will be produced by each parent: 
BBFF - BF, BF, BF, and BF
bbff - bf, bf, bf, bf
Using these gametes in a punnet square (see attached image), one will notice that all of the offsprings will have the genotype: BbFf i.e all or 100% of the offsprings are heterozygous for both of the genes or traits. 
 
        
             
        
        
        
I think the correct answer from the choices listed above is option A. In plants, the purpose of auxins is to produce phytochrome. The main function of auxin is to help plants grow. Auxin stimulates plant cells to elongate, and the apical meristem of a plant. Hope this answers the question.
        
             
        
        
        
The set of Wavelength is absorbed by pigment. So in a typical leaf some pigment can’t be visible.
Explanation:
There are mainly three types of key pigments in photosynthesis.  These three key pigments are Chlorophyll a, Chlorophyll b, and β-carotene. Those set of wavelengths which is not absorbed by pigment and finally it is reflected and that reflected light is what we see as a color.
The reason behind color of plant looking green because it contains huge amount of chlorophyll a and b molecule. It reflects the green light.
