What is the kingdom archezoa?
The kingdom archezoa was meant to classify organisms that developed before the mitochondrial stage; however, it has since been discovered that most organisms develop with mitochondria and this kingdom has been largely abandoned.
The concept that new varieties of organisms are still evolving is best supported by the?
concept of natural selection. Natural selection is a key mechanism driving evolution, as it favors traits that increase an organism's chances of survival and reproduction in a given environment. The ongoing process of natural selection contributes to the continual adaptation and evolution of new varieties of organisms.
How yeast cells can be considered single-celled organisms when they are still connected together.?
Yeast cells are considered single-celled organisms because each yeast cell can carry out all the necessary functions for life independently, including metabolism, reproduction, and response to environmental changes. While they can form multicellular structures or colonies, such as chains or clusters, these connected forms do not function as a single organism. Each individual yeast cell retains its autonomy, allowing it to live and reproduce independently, which aligns with the definition of single-celled organisms.
When one of your classmates states a hypothesis that all organisms must have organ systems is your classmate's hypothesis valid?
From wikipedia.org Organs exist in all higher biological organisms, in particular they are not restricted to animals, but can also be identified in plants. In single-cell organisms like bacteria, the functional analogues of organs are called organelles.
If evolution is true shouldn't we find living organisms or fossils with half-developped important organs such as half a lung or half an eye?
Evolution doesn't necessarily produce incomplete or half-developed organs because intermediate stages can still provide a survival advantage. Incomplete structures, like half an eye, could provide some function, such as detecting light, which could be advantageous in survival. Additionally, many transitional forms with different stages of organ complexity have been found in the fossil record.
Do evolution stop?
No. Evolution is the change in allele frequency over time in a population of organisms. This may be the result of stabilizing selection, but is still evolution.
What is the kingdom archezoa?
The kingdom archezoa was meant to classify organisms that developed before the mitochondrial stage; however, it has since been discovered that most organisms develop with mitochondria and this kingdom has been largely abandoned.
The distribution of different organisms over the surface of the earth offers evidence for?
the theory of evolution through natural selection, as it shows how species have adapted to different environments. This distribution reflects the process of speciation and evolution, where organisms have diversified to inhabit a wide range of habitats and niches.
The most primitive phyla to still have a head and organs is?
Platyhelminthes !
Has the rite of spring lost its primitivism?
No. It is still as primitive as ever.
The concept that new varieties of organisms are still evolving is best supported by the?
concept of natural selection. Natural selection is a key mechanism driving evolution, as it favors traits that increase an organism's chances of survival and reproduction in a given environment. The ongoing process of natural selection contributes to the continual adaptation and evolution of new varieties of organisms.
Is the Human race still in a state of primitive technology?
I think the human kind is not in the primitive stage anymore. We are in the modern stage right now.
Which medicine was created in the Primitive Era and is still used today?
morphine
How does Lamarck explain that organisms have a tendency to adapt and improve yet throughout the world the lowest forms of life still exist?
Obviously he was wrong. Organisms evolve, Evolution is not progressive, does not plan for the future and is not linear. The average tendency is for organisms to become more complex, but someone forgot to tell barnacles and tape worms, among others, as they have got less complex. Evolution is only change over time and Lamarck was wrong about ' improvements. '
Why do people think mars had life?
There was a possibility that there had been inthe far past. There is evidence of running water for example. Now long gone. It was not so much as thinking there had been, or still was, primitive organisms, it was checking to see if there was any evidence.
Does a promontional single from a cd still count as a single?
A promotional single from a CD is still a single. A single is one.
Why we can't die easily?
Evolution produces species that have the ability to survive and to reproduce. Organisms which die too easily would have died out long ago and would not still be present in the world as living species.
