True-breeding flies with singed bristles (s) and normal wings (L) were crossed to true-breeding flies with normal bristles (S) a

mina [271]

Answer:

The correct answer is -

Possible F2 offspring genotypes and phenotypes:

SsLl: normal bristle, normal wing

Ssll: normal bristle, vestigial wing

ssLl: singed bristle, normal wing

ssll: singed bristle, vestigial wing

Explanation:

In this case, the genes 's' and 'L' and genes 'S' and 'l' are linked, they will be passed on to the gamete together.

The cross would be as follows:

F1:

Parents: singed bristles and normal wings x normal bristles and vestigial wings

Genotype: ssLL SSll

Gametes: sL Sl

F1: SsLl ( normal bristles and normal wings )

For F2,

Parents: normal bristles and normal wings x singed bristles and vestigial wings

Genotypes: SsLl ssll

Gametes: SL, Sl, sL, sl

Cross:

SL Sl sL sl

sl SsLl Ssll ssLl ssll

Thus the possible offspring will have -

SsLl: normal bristle, normal wing

Ssll: normal bristle, vestigial wing

ssLl: singed bristle, normal wing

ssll: singed bristle, vestigial wing

Possible contaminate will be Proteus or Salmonella. To differentiate the two genera urease test can be accomplished. However, urease test, Proteus will produce a positive test result.

This test can be done to determine the ability of an organism to split urea. The principle of urease test is that urea is the product of decarboxylation of amino acid. Splitting of urea via hydrolysis will produce ammnonia and CO2. The CO2 produce allows the formation of bubbles.

state the name for chemicals that are secreted by glands into the blood and that affect organs elsewhere in the body

tamaranim1 [39]

The name of chemicals that are secreted by glands into the blood and those that affect organs elsewhere in the body are known as Hormones.

<h3>What is Gland?</h3>

A Gland may be defined as an organ in the human or animal body that perspires certain chemical substances for usefulness in the body or for liberation into the surroundings.

The endocrine glands are responsible for the synthesis of such chemical substances into specific body parts and organs and pass them directly into the bloodstream. These chemical messengers are thought to be the agents of communication between one body part and another.

Therefore, it is well described above.
