Sweet yellow tomatoes with a pear shape bring a high price per basket to growers. Pear shape, yellow color, and terminal flower

position are recessive traits produced by alleles, f, r, and t, respectively.
The dominant phenotypes for each trait – full shape, red color, and axial flower position – are the product of dominant alleles F, R, and T. A farmer has two pure-breeding tomato lines. One is full, yellow, terminal and the other is pear, red, axial. Design a breeding experiment (crosses) that will produce a line with tomato that is pure-breeding for pear shape, yellow color, and axial flower position.

Answer and Explanation: The farmer has a pure-breeding line of tomato means the farmer has a tomato with genotype FFrrtt while the other line of tomato has genotype ffRRTT.

The cross between these lines gives a F1 generation of heterozygous full, red and axial or FfRrTt.

With an individual of F1 crosses with another individual of F1, the Punnet Square will be:

FfRrTt x FfRrTt

1) Dividing each characteristics, for simplicity:

          F         f

F       FF       Ff

f        Ff        ff

          R       r

R       RR     Rr

r        Rr      rr

         T      t

T       TT   Tt

t        Tt     tt

Analysing Punnett squares, we notice the line wanted (ffrrTT) will be produced, when an individual of F1 generation cross with another individual with the same generation.

Verizon [17]

Answer:

The options

1

Have dilute urine."

2

Be unable to urinate."

3

Produce dark red urine."

4

Experience some burning on urination."

The CORRECT ANSWER IS 4

4

Experience some burning on urination."

Explanation:

Due to the trauma affecting the mucous membranes of the urinary tract, burning on urination is a more likely response, this sensation gets to reduce with time. This will stop the urine from further dilution once the frequent continuous bladder irrigation is stoped and removed. Although, the urine may show a slight pink tinge which results from the trauma after the surgery and the effect of the catheter that is noticed. A difficulty to urinate won't be felt except the indwelling catheter is removed earlier than it should expected and edema still occurs in the urethra. Production of dark red urine is an indicative factor for hemorrhage, which ought not to be seen.

Human decisions about controlling erosion have very little effect on living conditions.
Vika [28.1K]

Answer:

False

Explanation:

The main cause of man-made erosion is agriculture, followed by construction and mining.

Where humans once used sticks and stones, they have since developed technology that dramatically accelerated the speed of erosio.

Hence, if human descions are to control the soil erosion then there will be a very big impact on living conditions.
