Answer:

The combinations of gametes that could be produced from heterozygous individuals for both traits are PT, Pt, pT and pt.

Explanation:

An individual is heterozygous for two traits, flower color and stem height, with a PpTt (dihybrid) genotype and a phenotype showing the dominant traits, purple flowers and tall stem.

The genes of this individual for the above-mentioned traits contain different alleles, and taking into account the independent segregation of characters, the alleles present in its gametes could be:

  • <em>Both dominant alleles: PT </em>
  • <em>One dominant and one recessive allele Pt or pT </em>
  • <em>Both recessive alleles: pt </em>

Therefore, the traits of its offspring will depend on the alleles for those traits present in the gamete to which they are combined.

In the energy pyramid below, what would most likely happen to all other levels if a disease killed off all of the rabbits? *
Pavlova-9 [17]
The answer is A. Rabbits eat grass. The snakes eat the rabbits and the hawks eat the snakes. So if rabbits died off, so would the snakes, and the hawks. Because both of their food sources would deplete. And grass would flourish.

Select the layers of Earth that are completely solid. A. crust B. inner core C. outer core D. lower mantle E. asthenosphere
melisa1 [442]

Answer:

The correct answer would be A. crust.

The crust is the outermost layer of the earth which is composed of different types of rocks such as sedimentary, metamorphic, and igneous rocks.

It is completely solid and can be broadly classified into two types: continental crust and oceanic crust.

The thickness of the oceanic crust is about 5 km to 10 km. It is primarily composed of basalt, gabbro, and diabase.

The thickness of the continental crust is around 30 km to 50 km.  

The crust forms lithosphere along with hard and upper mantle.

Many different organisms live in Amanda’s garden. The diagram shows a simple food web of some of the organisms in her garden.
Alex787 [66]

Answer:

The snakes keep the mice from overpopulating, which could deplete their resources.

Explanation:

The mice and the moles are not competing against each other as they feed on different food. The problem is that if the mice population is not regulated, their very quick reproduction will cause overpopulation in very short space of time. The more mice there will be , the more food will be needed, so very soon the resources will be depleted, resulting in collapse of the mice population. This is where the snakes come in action, as they eat mice, so they are the ones that control and keep their population stable, thus not allowing the mice to overpopulate the area and destroy themselves.
