Two scientists test soil fertility in a forest and a nearby field. Both scientists find that the soil fertility in the forest is

higher than the soil fertility in the field. Scientist A says that the forest's soil fertility is higher because the forest has more vegetation that keeps the topsoil from eroding. Scientist B says that the forest's soil fertility is higher because the forest's soil has a high count of decomposing bacteria. Which of the scientists' conclusions is valid?
Neither scientist's conclusion is valid because soil fertility is hard to test.
Only scientist A's is valid because it is supported by evidence.
Only scientist B's is valid because bacteria increase soil fertility.
Both scientists' conclusions could be valid.

<u><em>Both scientists' conclusions could be valid.</em></u>

There are many ways to interpret data. Both of the scientists present a possible way to interpret the forest's higher soil fertility. Neither interpretation can be disproved without further research.

The inheritance of eye color in Drosophila is controlled by genes on each of the fly's four chromosome pairs. One eye-color gene
algol [13]

Answer:

F1 Females  - all wild type

F1 Males  - all wild type

F2 Females  -  - all wild type

F2 Males - 1/2 wild type, 1/2 vermilion

Explanation:

The wild-type allele (Xᵛ⁺) is dominant over vermilion (Xᵛ), which is a sex-linked trait.

Female flies have two X chromosomes, male flies have one X and one Y chromosome.

A homozygous wild-type female fly (Xᵛ⁺Xᵛ⁺) is mated with a vermilion male fly (XᵛY).

The female parent can only produce Xᵛ⁺ gametes.

The male parent can produce either Xᵛ or Y gametes.

When gametes from both parents fuse, the F1 offspring will have the genotypes Xᵛ⁺Xᵛ (females with wild type eyes) and Xᵛ⁺Y (males with wild type eyes).

The F1 females can produce Xᵛ⁺ and Xᵛ gametes. The F1 males can produce Xᵛ⁺ and Y gametes.

When the F1 individuals interbreed, the gametes combine to give rise to the F2 offspring. The possible combination of gametes that will give the different genotypes and phenotypes in the F2 are:

  • Xᵛ⁺Xᵛ⁺ females with wild type eyes
  • Xᵛ⁺ Y males with wild type eyes
  • Xᵛ Xᵛ⁺ females with wild type eyes
  • Xᵛ Y males with vermilion eyes

What passes through a cell using passive transport?
Tanzania [10]
Passive transport is a movement ofbiochemicals and other atomic or molecularsubstances across cell membranes without need of energy input. Unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy. The rate of passive transport depends on thepermeability of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane lipids andproteins. The four main kinds of passive transport are simple diffusion, facilitated diffusion, filtration and osmosis.
