What group of organisms is found at the base of every energy
pyramid?
Answer:
Plants or other photosynthetic organisms (autotrophs) are found on the first trophic level, at the bottom of the pyramid. The next level will be the herbivores, and then the carnivores that eat the herbivores. The energy pyramid (Figure below) shows four levels of a food chain, from producers to carnivores.

Which of the statements are characteristics of a good hypothesis? -is developed from data that cannot be replicated -relies heavily on cutting edge technology -is created from careful research and logical reasoning -is based only on a presentation by an expert in the field -is able to be tested using validated techniques
Answer:
is created from careful research and logical reasoning
is able to be tested using validated techniques
Explanation:
A hypothesis can be defined as a prediction/expectation that is made in order to understand a phenomenon from the real world. This prediction must be testable and measurable by using the scientific method. In science, a good hypothesis clearly defines the relationships between two or more variables (independent variables and dependent variables). Moreover, a good hypothesis must also be written in simple and precise language, which means that its statements must be understandable (and verifiable) for any person and/or researcher working in the field.

Answer:
The cosmos?
Explanation:
When humans come to a previously pristine environment, they inadvertently bring organisms with them that can be harmful to the local flora and fauna. Such organisms are known as _____.
Answer:
INVASIVE species
Explanation:
In biology, an organism is said to be INVASIVE if the organism is foreign to a particular region or habitat and possess the unpleasant ability to proliferate or grow rapidly to the point of competing with local species of organisms.
According to this question, humans are said to introduce organisms that have the ability to harm the local flora and fauna. Hence, these organisms are INVASIVE SPECIES because they are foreign to that place and cause damage in their new environment.
Eukaryotic cells grow and divide through a series of events called the
cell cycle as shown in the diagram below. Based on the information
provided, what are the three main phases of the cell cycle?

Water can travel upwards in the small tubes within plants. This is:
A. Surface Tension
B. Adhesion
C. Cohesion
D. Capillary Action
Answer:
D i think maybe right not sure
Answer:
D. Capillary action
Explanation:
Capillary action is defined as "the movement of water within the spaces of a porous material due to the forces of adhesion, cohesion, and surface tension." All of the other answers are technically right because they are all present when the water is traveling upward, but Capillary Action is the most correct answer provided because it is the description of what is hapeneing as a whole.

How did you determine the types of cell division for both phases depicted in your model? Explain your answer.
Answer:
Cell division is a process that makes our skin, tissues, muscles, sex cells. It is the building block of our body.
Explanation:
When parents cells ahs been divided into two or more than two daughter cells then it is called division of cells. The division of cells occur as a larger cell. When we talk about eukaryotic cells, these cells divided into two distinct types of the cells, the vegetative cells.
The daughter cells are the identical to the parents cells genetically. There are two types of division such as mitosis and meiosis. When parents cells divides in daughter cells and daughter cells divided further, this process called the cells cycle. The mitosis cell division occur interphase. Meiosis cell division occur in two phase meiosis I and meiosis II.

Explain how waves eventually even out a shortline?
Answer:
They expend all their energy overtime
Explanation:
Scientists use a process called gel electrophoresis to separate DNA fragments. The process involves placing a mixture of DNA fragments at one end of a slab of porous gel. Then a power source is used to generate an electric potential across the gel.
The diagram shows the process of gel electrophoresis. First, DNA fragments, mixed with a restriction enzyme, are placed at one end of a slab of gel. Then a power source is applied; the longer DNA fragments stay near the negatively charged end, and the shorter fragments move toward the positive end.
Gel electrophoresis is successful because of which property of the DNA fragments?
A. The DNA fragments may be positively-charged, negatively-charged, or neutral.
B. The DNA fragments travel at different speeds through the gel.
C. The DNA fragments travel at the same speed through the gel.
D. The DNA fragments chemically react with the gel in different ways.
Answer:
C. The DNA fragments travel at different speeds through the gel.

Poison dart frogs live in the rainforest. They produce a poison by eating toxic fire ants. The only known predator is a snake, Liophis epinephelus. Which is most likely a density-independent factor that affects the poison dart population in the rainforest? clear cutting the rainforest limited food source susceptibility to disease increase in population of Liophis epinephelus
Answer:
Clear-cutting the rainforest
Explanation:
Density-independent factors of a population are factors that limit the size of a population irrespective of the density of the population.
A limited food source can only be defined by the size of a population, diseases will spread faster in high-density populations, and an increase in the population of a predator will cause a decrease in the population size of the predator's prey.
Clear-cutting of the rainforest means automatic destruction of the habitat of the poison dart frog's population, no matter the population size. Hence, clear-cutting of the rainforest is considered as the density-independent factor in this case.
Answer:
A.) clear cutting the rainforest

why is it important for environmental scientists to have a background in many fields of study
Answer:
With these rapid changes, there is a need to study each step that may alter the environment so that the natural ecosystem may still be protected or replaced by a better one. Environmental science is important to save our world from destruction. Because of man's abusive actions, the environment is not safe anymore.
