The statements which describe Rutherford’s model of the atom are as follows:
A. The atom is mostly empty space.
C. Electrons orbit around the center of the atom.
D. The atom's positive charge is located in the atom's nucleus.
<u>Explanation:</u>
According to the Rutherford model, an atom is largely empty space, comprising electrons that are negatively charged surrounding the nucleus, which is held by protons with a positive charge. An atom comprises a small, compact and positively charged nucleus where virtually all of an atom's mass is concentrated.The nucleus is accompanied by levels of energy which contain electrons that circulate around the nucleus with a negative charge. The model much like planets revolving around the Sun.
A cell is the smallest unit of life. Cells are often called the "building blocks of life". The study of cells is called cell biology. Cells consist of cytoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids.
Answer: a. negative
Explanation:
Your speed is decreasing so you are slowing down which is the opposite of accelerating forward so it will be negative.
Answer:
The answer is option D "Succession rates would depend on the number of early arriving facilitator species"
Explanation:
Ecologists have a solid interest in knowing how communities structure and change over the long run. Indeed, they have invested a ton of energy seeing how complex communities, such as forests, emerge from void land or uncovered stone. They study, for instance, locales where volcanic eruptions, ice sheet retreats, or out of control fires have occurred, clearing land or uncovering rock.
In examining these destinations over the long haul, ecologists have seen steady cycles of progress in natural communities. As a rule, a community emerging in an upset territory experiences a succession of movements in synthesis, frequently throughout numerous years. This arrangement of changes is called natural succession.
Succession is a progression of reformist changes in the structure of an ecological community over the long run.
In primary succession, recently uncovered or recently shaped stone is colonized by living things unexpectedly.
In secondary succession, a territory recently involved by living things is upset then recolonized following the aggravation.
