Which molecule supplies chlorophyll with electrons
True [87]

In light reactions, a molecule of chlorophyll absorbs one photon of light, causing a chlorophyll electron to transfer to a higher energy level. The energized electrons from the chlorophyll molecules flow down a transportation chain to a compound called nicotinamide adenine dinucleotide phosphate or NADP.

Assume that two genes are 80 map units apart on chromosome II of Drosophila and that a cross is made between a doubly heterozygo
STatiana [176]

Answer:

The recombination frequency between two genes exhibits a positive correlation with the distance between them, that is, farther they are, and more will be the chance of recombination. Thus, recombination frequency is used to signify distance among the two genes, for example, 1 percent recombination frequency demonstrates distance of 1 map unit.  

Let us consider that the heterozygous female of genotype AaBb can generate four kinds of gametes, that is, AB, Ab, aB and ab. Of these, the two gametes are the outcomes of recombination, or it can be said that 50 percent are recombinants. Thus, it can be concluded that in case of two linked genes, the maximum probable recombination frequency is 50 percent.  

This shows that any genes, which are distant than 50 map units will function as unlinked and will function as if they were on distinct chromosomes, and the frequency of recombinant frequency will be 50 percent.  

In the given question, it is given that the map distance between the two genes is 80 map units, that is, more than 50 map units. The maximum probable recombinant offspring will be 50 percent of the entire offspring.

How do tussock moths obtain energy in cellular respiration?
s2008m [1.1K]
Tussock moths obtain energy by cellular resporation by the oxidation of food they consume. The food they consume is oxidised to synthesize special type of phosphate which is then stored as energy. The energy is utilised by their cells whenever needed.
