Genrish500 [490]1 year ago
4 0

Answer:

The correct answer is - a false statement.

Explanation:

Tetraploid organism or the cell that has four sets of chromosome in their cell whereas diploid organism that contains two sets of chromosome in their cell. The fertile diploid and fertile tetraploid organism produce triploid organisms that are sterile in nature.

This cross would result in the triploid and the gametes will have uneven chromosome numbers in it that will not let the sexual reproduction possibly occur.

Thus, the correct answer is - a false statement.

A fossil mold that reflects the shape and surface markings of an organism is created when _____.
Lady bird [3.3K]

Correct answer: D). The organism is buried in sediment and then dissolved by underground water

Mold is a copy of an organism, it is formed like the first layer of sediments harden and forms a mold. Then after that new layer of sediment fills and become hardens.

The fossil is left behind in sediment, which removes the remains of an organism from its surrounding material. The groundwater along with its mineral content dissolves the organic matter to form the fossil.

Two true-breeding stocks of pea plants are crossed. One parent has red, axial flowers, and the other has white, terminal flowers
Debora [2.8K]

Answer:

Explanation:

<em>The probability of producing plants with white axial flowers would be 1/16.</em>

From the illustration, All F1 individuals had red, axial flowers. It thus means that red and axial genes are dominant over white and terminal genes in the pea plant.

Let us assume that the allele for flower color is A (red) and a (white); and the allele for flower location is B (axial) and b (terminal).

Pure-breeding red, axial flower = AABB

Pure breeding white, terminal flower = aabb

AABB   x    aabb

F1 genotype = AaBb - all red and axial

At F2:

AaBb   x   AaBb

Progeny

<em>9 A_B_ red/axial</em>

<em>3 A_bb red/terminal</em>

<em>3 aaB_ white/axial</em>

<em>1 aabb - white/terminal</em>

Hence, the probability of producing plants with white axial flowers in the F2 generation is 1/16.

Radiation can cause breaks in human chromosomes. However, insects can survive much higher lecels of exposure. Why?
galben [10]

Explanation:

The influence from radioactivity is inversely proportional to the number of chromosomes , since , humans have more DNA , chromosomes than the insects , and  therefore , due to less chromosomes in insects , they are more resistant towards radioactivity .

As the target of the radiation is the DNA .

Hence , It is clear that insect due to lesser DNA are less prone to Radiations .
