Answer:

C. In the egg outside the mother's body is the correct answer.

Explanation:

In oviparous animals, fertilized eggs develop externally.
In the oviparous animals, fertilization occurs internally but the embryo development occurs externally.when the embryo is developed than the egg hatches.

The fertilized eggs are laid outside and each fertilized eggs carries an embryo.

Thus In oviparous animals embryo development take place in the egg outside the mother's body.

Examples of oviparous animals are bony fish, reptiles, some type cartilaginous fish,amphibians and birds.

In pea plants, the allele for purple flower color is dominant to the allele for white flower color. If you were to perform a tes

Furkat [3]

Answer:

In pea plants, the allele for purple flower color is dominant to the allele for white flower color. If you were to perform a test cross to determine the genotype of a purple-flowered plant, what would you expect the phenotypic ratio of purple-flowered to white-flowered progeny to be if the plant is homozygous? And what would you expect if the plant is heterozygous

D. If the purple-flowered plant is homozygous, than the progeny would all have purple flowers; if the purple-flowered plant is heterozygous, then the progeny would have purple to white flowers in a 3:1 ratio.

for homozygous plant, the genotype progeny would be Pp, Pp, Pp, Pp

ratio of purple-flowered plant would be 4:0 all purple

for heterozygous plant, the genotype would be PP, Pp, Pp, pp

ratio of purple-flowered would be 3:1

Explanation:

From the above experiment

let purple flower be represented with P

Let white flower be represented with p

then;

for homozygous plant, the genotype progeny would be Pp, Pp, Pp, Pp

ratio of purple-flowered plant would be 4:0 all purple

for heterozygous plant, the genotype would be PP, Pp, Pp, pp

ratio of purple-flowered would be 3:1

Which is the correct name for the warmer phase of the ENSO cycle

NikAS [45]

La Niña is sometimes referred to as the cold phase of ENSO and El Niño as the warm phase of ENSO. These deviations from normal surface temperatures can have large-scale impacts not only on ocean processes, but also on global weather and climate.
