One is drift netting. These nets are indiscriminate and also catch, injure and kill fishes that are not intended to be caught. This, therefore, greatly affects the marine ecosystem. 

Second is over-fishing. This reduces the fish population to a point where they are unable to regenerate and hence predisposes/ condemning them to extinction   

Third is the destruction of marine ecosystem, deliberately, to clear an obstacle or pave the way for fishing lines. This damages the habits hence affecting the ecosystem from primary producers and up the food chain.

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.

Which of the following is TRUE about this reaction?
hoa [83]

The right answer is C

This process is called anaerobic respiration. It doesn't need dioxygen to occur (it can happen with or without O2).

Anaerobic respiration is a mechanism in which electrons pass through a chain of transporters whose final acceptor is a mineral substance other than oxygen, unlike aerobic respiration where the final acceptor is dioxygen. The final acceptor may be the nitrate ion (as in the case of Pseudomonas), carbon dioxyde or the sulfate ion.

Some bacteria (Pseudomonas) are able, anaerobically, to reduce nitrates to nitrites and then, depending on the case, to dinitrogen (with the enzyme Nitrate reductase A).

NO3- ==> NO2- ==> N2.
