Seeds of dandelion also adapted seed dispersion tactic by seed-parachutes into the wind.  Dandelion weed does not require to be pollinated and rapidly increases their numbers. Dandelion has a taproot that goes deep into the soil, up to three feet down for water and nutrients.

Nikitich [7]

Answer:

The phylogenetic graph uses several types of variables to be formed, while other models use only one type of variable.

Explanation:

To create a phylogenetic chart, matrices with data on the studied species are used. These data are composed of morphological, chemical and / or genetic information that allow a detailed investigation about the ancestry of each species, in addition to allowing the correct grouping based on this ancestry and evolution.

A phylogenetic graph is different from other molecular models due to the number of data considered by it, since other models, such as the molecular clock, for example, only consider genetic based information.

Fruit flies have eight pairs of chromosomes. Calculate the genetic possibilities from independent assortment of a zygote made fr
Furkat [3]

Answer:

256

Explanation:

If there are 2 pairs of chromosomes Aa and Bb, there are 4 possibilities for independent assortment of gametes:

A w B, aith with b, A with b and a with B.

If there are 3 pairs of chromosomes Aa, Bb and Cc, there are 8 possibilities:

ABC, abc, ABc, Abc, aBC, aBc, abC, AbC

This corresponds to 2^n, where n= the number of chromosomes.

Therefore, with 8 chromosomes, the possibilities are 2^8 = 256

This is for each parent.

Explanation:

The double red program is a program where red blood cells are donated by people . This red blood cells are used for treatment of patients that require red blood cells such as transplant of organs, transplant of tissues, treatment of cancer e.t.c.

Apheresis is a process whereby blood is collected or removed from the body and it undergoes the process of filtration into various components of the blood.

The machine that is used during apheresis collects the human blood and separates it into white blood cells, red blood cells and platelets.
