Taxonomy is the branch of Science, in which
we study the Classification of Organisms. On discovering an unknown organism,
begin classification by looking for anatomical features that appear to have the
same function as those found on other species.
In order to correctly classify an organism,
scientists use many modern tools.
1.Morphology describes the physical
characteristics of an organism. Typically, this is enough information to place
the organism within a domain and kingdom.
2.DNA and biochemical analysis allow
scientists to test less visible, but distinguishing, characteristics.
3.Comparing embryology allows scientists to
group organisms that share common fetal development.
<span>4.Evolutionary
phylogeny describes the evolutionary relationships between organisms.</span>These
relationships are deduced based on shared traits that may have been passed from
ancestor to new species. Traits
may include physical traits (ex. presence of jaws), or may be genetic traits
(shared genes).
Answer:
1) IRIS
2) LENS
3) RETINA
4) Fovea Centralis
Note: Answers 1 - 4 follows question pattern
Explanation:
The PUPIL is the hole in the MIDDLE of the IRIS of the eye, through which light passes to be focused on the RETINA.
The IRIS is the contractile membrane perforated by the pupil, which adjusts to control the amount of light reaching the retina, and which forms the colored portion of the eye
ACCOMMODATION is the change in the adjustment of the eye lens to help focus light ray.
RETINA helps to receive light rays that the lens has focused. It contains two cells: rods and cones
Fovea Centralis is at the center of the retina responsible for sharp and accurate vision, also it is where cones cells cluster.
Answer:
"The smallpox vaccine does not contain smallpox virus and cannot spread or cause smallpox. However, the vaccine does contain another virus called vaccinia which is live in the vaccine. Because the virus is alive, it can spread to other parts of the body or to other people from the vaccine site."
[Copy and pasted from a medical website]
Answer:
true
Explanation:
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Answer:
Explanation:
5. "Although there is some disagreement, several types of marine ecosystems are largely agreed on: estuaries, salt marshes, mangrove forests, coral reefs, the open ocean, and the deep-sea ocean. An estuary is a coastal zone where oceans meets rivers."
6. "the ecosystem is changing making it easier for people to live"
7. "A positive effect would be the organism getting the right amount of nutrients if the ecosystem went fast everything would happen so fast that the ecosystem won't turn out right and the fast change with case the wrong amount of nutrients from the change happening so fast."
