I'm pretty sure organic materials are considered sediments and not minerals because organic materials come from the Earth's surface. Minerals must be mined for in order to find.

Answer:

Sediments are defined as the particles that are derived from the weathering of rocks on the surface of the earth. These are formed in the terrestrial areas. One of the types of sediment is the biogenous sediments which are derived from the dead organic matters of plants as well as animals. These remains of plants and animals are also known as organic sediments as they are directly derived from the surface and are found as a mixture of both rock fragments as well as dead remains of flora and fauna.

In order to be a mineral, the particle must be naturally occurring with a specific chemical composition and internal atomic structure.

This is why the organic material are considered to be sediments but not as minerals.

soldier1979 [14.2K]

Answer:

All the offsprings would be heterozygous purple colored flower

Explanation:

Given

Purple color flower is dominant over white color flower

Let the allele for purple color of flower be represented by "P"

and the allele for white color flower be represented by "p"

A pea plant that is homozygous purple-flowered is crossed with a pea plant that is white-flowered.

Genotype of homozygous purple-flower is "PP"

and Genotype of homozygous white-flower is "pp"

Cross between PP and pp produce the following offspring

PP * pp

Pp, Pp , Pp , Pp

All the offsprings would be heterozygous purple colored flower

Assuming no genetic recombination, how many genetically distinct types of gametes can a single human being make?

Answer:

Explanation:

Each chromosome represents a twin.like pairs of socks.

This is an analogous problem: you have 2 pairs of socks, one white, one black. Each of the sock is tailored to a specic foot, right or left. How many different ways can the socks be mixed and matched , one for each foot?

Here are the possibilities : left = black, right = black is one such match. Left = white, right = black is another.

so also we will have 23 chromosome pairs
