A phylogeny is an evolutionary ”tree” of related
organisms that can be constructed by using
information obtained from the genetic material.
Genetic information is contained in all living cells,
in the form of long DNA molecules that take the
shape of connected double- stranded spirals
(DNA stands for deoxyribonucleic acid). DNA
spirals, or “helixes”, are tightly compressed in the
nucleus of every cell. Their information is
organized into a code made up of four small
molecules — the building blocks of DNA. The
molecules, called nucleotides, are labelled:
A (adenine), C (cytosine), G (guanine) and T
(thymine).
It is possible to draw conclusions about the
evolution of a group of plant or animal species,
and the relationships among them, by comparing
selected pieces of DNA.
It is a method in the textile industry where two sets of threads are interwoven at the right-angles to form a cloth
<u>Explanation:</u>
<u>1.100% cotton:</u>
- open weave.
- easily distorted with water and washing.
- stretches in one direction only.
<u>2. 100% wool:</u>
- very strong.
- dense and compact.
- different faces.
- diagonal design.
- soft and pliable.
<u>3. 100% Nylon Rope:</u>
- Not durable.
- Tends to snag
- The shiny surface.
- high light reflectance.
- light fiction with other garments.
<u>4. 100% Spandex Nylon:</u>
- Not durable.
- Tends to snag and break during wear.
- light fiction with other garments.
<u>5. 100% cotton blend</u>
- easily distorted with water and washing.
Causes:
1. the increase in population and growth of the human race
2. the need for housing and industrial advancements
effects:
1. loss of habitat for wildlife
2 loss of trees for oxygen
A biome is best described as a major type of ecosystem with SYSTEMS OF HABITATS HAVING DIFFERING CLIMATES.
hope this helped!
