What experimental evidence led to the development of this atomic model from the one before it? A few of the positive particles aimed at a gold foil seemed to bounce back. The colors of light emitted from heated atoms had very specific energies. Equations were used to identify regions around the nucleus where electrons would likely be. Cathode rays were bent in the same way whenever a magnet was brought near them.
Few positive particles aimed at a gold foil seemed to bounce back is the evidence that is responsible for the development of atomic model. Rutherford performed an experiment in which alpha particles are allowed to fire on the gold foil.
Some of the particles bounced back which tell us that there are heavy particles present in the center of an atom.
Most alpha particles pass through the atom which tell us that there is a lot of empty space in an atom.
There is also a slight deflection that occur due to similar charge that tells us the element which is present in the nucleus has positive charge.

scientist adds energy to a
block of metal. According
to the kinetic theory, what
should the scientist predict
will happen to the metal?
Answer:
According to the kinetic energy, the atoms of the metal will become very energetic and will tend to vibrate more within their lattice structure.
As the atom becomes more energetic the atoms become more and more energetic tending to wriggle free from the crystalline metallic structure making the metal more malleable.
With the addition of more energy, the atoms of the metal will become more energetic than the inter atomic metallic bond and the metal starts to melt into liquid metal.

In the Endosymbiotic Theory for the origin of eukaryotes, the final step was the engulfing a functional cyanobacterium to produce photosynthetic eukaryotes ("plants"). Why is this stage considered the final step in the sequence of eukaryote evolution?
Answer:
The Endosymbiotic Theory of eukaryote evolution is known as Symbiogenesis that states the evolution of eukaryotic cells from prokaryotic organisms.
The engulfing a functional cyanobacterium to produce photosynthetic eukaryotes ("plants") is considered as final step of the eukaryote evolution because a functional cyanobacterium closely resemble the chloroplast and related to mitochondria and it maintains a large genome that encodes thousands of proteins.
A photosynthetic eukaryotes ("plants") require cholorplast (green pigment) for photosynthesis and protein synthesis, which all are provided by functional cyanobacterium, after that a eukaryote can functions as an individual eukaryote and not as prokaryote, and hence engulfing functional cyanobacterium is considered as last step of eukaryote evolution.

Auxin is a plant growth hormone (phytohormone) which is responsible for the cell division and large amounts of auxin inhibits the growth of roots in plants. Thus, the correct option is C.
What is Auxin?
Auxins are a class of phytohormones which show some morphogen-like characteristics. Auxins play the main role in coordination of growth and behavioral processes in plant life cycles. These are essential for the development of plant body.
Auxin is a key regulator of growth and development in plant, cell division, elongation and differentiation, development of embryo, root and stem tropisms, apical dominance, and flowering in plants.
In the shoots, auxin hormone stimulates cell elongation and the presence of high concentrations of auxin in plants promote growth. However, in the roots auxin hormone inhibits the cell elongation and therefore high concentrations of this hormone limits growth in plants.

What are the CONSTANTS in this experiment?
Help- this is for a grade :,
Answer:
INDEPENDENT variable - type of floor cleaner
DEPENDENT variable- numbers of scratches
Constants : number of test sections and size of test sections
Explanation:
Independent variable is a variable which is change dependent variable by manipulated itself, type of floor cleaner costly one or cheap one is independent variable in this case.
Dependent variable is a variable which is analyzed or measure in experiment it is something that shows response to the independent variable. In this case number of scratches before using cleaner and after using cleaner.
Constants is something in experiments that does not change in the experiment. Number of test sections and size of test sections is constant here in this case.
Indicate differences between oogenesis and spermatogenesis 1. final number of gametes produced 2. timing of meiosis II 3. timing of onset of prophase I 4. final number of chromosomes in the mature gamete
The correct options indicating the difference s between oogenesis and spermatogenesis are;
1) Final number of gametes produced.
2) Timing of Meosis 2
3) Timing of onset of prophase 1
Oogenesis is process by which a diploid germ cell known as an oogonium which is found in the fetal ovary thereafter becomes a haploid ovum in the adult species after fertilization must have taken place.
During the initial stage of oogenesis,the diploid germ cell moves from the yolk sac to the fetal ovary from there, further mitotic division will occur.
Spermatogenesis on the other hand is simply the process by which haploid spermatozoa get developed from germ cells and finally to sperm production,this occurs in the seminiferous tubules of the testes.

Explanation:
1. Which of the following correctly identifies the composition of an oxygen atom?
8 protons, 8 electrons, and 8 neutrons
6 protons, 6 electrons, and 6 neutrons
8 protons, 6 electrons, and 7 neutrons
06 protons, 6 electrons, and 12 neutrons
Answer:
The answer is A. 8 protons, 8 electrons, and 8 neutrons.
Explanation:
This is because Oxygen's atomic number is 8 and its atomic weight is 15.99 units. The atomic number is the number of protons in an atom. This means that there are 8 protons, along with 8 electrons, because the amount of electrons in an atom are equal to the number of protons (not including ions.) Additionally, to discover the amount of neutrons present in the given atom, you must take the atomic weight and subtract the atomic number (aka # of protons present). Once you subtract, you will be left with the number of neutrons. Since the atomic weight is 15.99, you will round it up to 16 and subtract 8, leaving 8 neutrons present. In all, it has 8 protons, 8 neutrons, and 8 electrons.

Does mixing compost with soil improve the growth of plants?
Answer:
yes!
Explanation:
Mixing compost with soil provides nutrients for plants today but also enhances soil for future years. The amendment naturally breaks down, releasing important macro- and micronutrients while feeding the beneficial biological organisms in the soil. It also increases the porosity of the soil and helps conserve moisture.
