Answer:
Plants are generally considered the best indicators of the level of succession in an ecosystem. Explain how you got your answer.
Explanation:
Plants are generally forms the basis of life in any environment, other organism strictly depends for survival and continuation of life as they are the only autotrophs in the food chain. The best indicator of the level of succession in an ecosystem remains the plant
Answer:
Vestigial Structures
Explanation:
Trace structures are a rudimentary (or even functionless) version of a body part, but they perform important functions in a closely correlated, or evolutionarily close, species. That is, they are structures that have been reduced in size, usually over time, and have less important function in some related organisms than in others.
The existence of these vestigial structures is strong evidence that evolution occurs in organisms, since this structure, today without much apparent function, may in the past have been extremely important to the ancestors of that species. We take as an example what happens to some vertebrates, such as fish, amphibians, reptiles, birds and mammals.
Answer:
Vestigial Structures
Explanation:
El cuerpo tiene tres sistemas principales de energía que puede usar para diferentes tipos de actividad física. Estos se llaman:
_sistema ATP-PC (fosfágeno);
_sistema glucolítico anaeróbico o ácido láctico;
_sistema aeróbico, que comprende los _sistemas glucolítico (carbohidrato) y lipolítico (grasa).
The water of any nature is essential for survival and reproduction. Cane toad can produce eggs ranges from 8,000 to 35,000 at a time. There are two conditions for healthy development which are described as follows:
In this way, cane toads make population successful during the life cycle.
Cane Toads are very strong and adaptable, they are also poisonous throughout its life cycle, which is why they only have a few predators and have a life span of 10-15 years. Cane toads have poison glands, and the tadpoles are extremely toxic to most animals if consumed. They are productive breeders, they only need a small pool of water of almost any nature. The female cane toads can lay 8,000 to 35,000 eggs at a time and may produce two clutches in one year. The eggs will hatch within 24-72 hours and the tadpole stage may last from three to twenty weeks. Cane toads in the tropics grow really quick and may be sexually mature only within one year. Cane toads have been introduced to many regions of the Pacific and the Caribbean islands as a method of agricultural pest control because of their ravenous appetite, however, they are now considered pests and are dangerous to humans and animals, both wild and domesticated especially to dogs.
In order to work as an environmental scientist.
Answer:
You need to use the scientific method and knowledge of the environment in order to work as an environmental scientist.
Explanation:
An environmental scientist should have an excellent knowledge about the systems of the environments and scientific methods. If a scientist is thorough about his understandings of the environment, he will be able to recognize any changes in the environment immediately and formulate the necessary reasons for the changes by using the scientific method of research. By using the scientific method of research, a scientist is able to learn about the various phenomenon occurring in the environment.
b. modern bacteria
c. archaebacteria
d. fungi
Answer:
c. Archaebacteria are the oldest fossil forms
Explanation:
According to the Six Kingdom Classification of Living Organisms, Archaebacteria includes the earliest organisms to have appeared on the earth's surface living under harshest of conditions. These were unicellular organisms that used chemical energy to synthesize life sustaining molecules(chemoheterotrophs).
As the temperature, pressure and environment became more conducive to live slowly they evolved into modern bacteria, and subsequently higher-ordered multicellular organisms. Fungi, Plant and Animals later evolved as the organization became more and more complex.
Therefore in chronological order the oldest fossils are Archaebacteria>modern bacteria>fungi>animals
