Answer:
Cell----- Tissue----- Organ---- Organ system
Explanation:
All living organisms are made up of cells. However, multicellular organisms contains many different kinds of cell, which are required to perform certain roles that will be of utmost benefit to the organism as a whole. The level of organization of life follows an hierarchical classification.
As earlier stated, CELLS are the simplest unit of every living organism. Cells that come together to function in a similar role are called TISSUES. Tissues that work together collectively form an ORGAN. Organs that perform similar functions to achieve a similar goal are called the ORGAN SYSTEM. The different systems in a multicellular organism makes up the whole ORGANISM.
Hence, Cell----- Tissue----- Organ---- Organ system is the organized level of organization from the smallest (cell) to the largest (organ systems).
Answer:
DNA evidence revealed the American vultures share more recent ancestor with the Storks
Explanation:
The hooded vultures that is mostly found in the African continent have a close resemblance with the American vultures and were traditionally classified to belong to the Falcon family.
However, it was observed that the American vultures shared a similar behavior with Stork which is not common to the vulture found in Africa, including the hooded vulture. The Stork and the American vulture exhibit the behavior of urinating on their legs when being overheated. When the urine gets evaporated, it helps them to cool their body temperature.
This shared behavior between the storks and the American vultures led scientists into using molecular analysis in analyzing the DNA of the hooded vultures found in Africa, the American vultures, and the stork.
Evidence from the DNA analysis later revealed that the American vultures and the storks share a more common DNA sequences than African vultures and American vultures do.
Tachycardia, cough, sore throat, asthma, nausea, and vomiting are among the short-term risks associated with smoking
Answer:
Much change is due to random genetic drift rather than positive selection. Some are harmful and are likely to be eliminated by natural selection – by death of the embryo, for instance. ...
