Fruit fly cells have 8 chromosomes. After mitosis, you would expect a resulting fruit fly daughter cell to have how many chromosomes? Explain your answer.
After mitosis, it is expected that the daughter cells of a fruit fly with 8 chromosomes should have 8 chromosomes.
MITOSIS:
Mitosis is the kind of cell division in which a single cell produces two daughter cells that are genetically identical to the parent cell. Mitosis results in daughter cells that possess the same number of chromosomes as the parent cell, hence, it is called duplication division. This means that mitotic division maintains the chromosome number of parents in the daughter cells. For example, a fruit fly with 8 chromosomes will produce daughter cells with 8 chromosomes each. Therefore, after mitosis, it is expected that the daughter cells of a fruit fly with 8 chromosomes should have 8 chromosomes.Learn more at: https://brainly.com/question/3327479?referrer=searchResults

239 Np -> 239 Pu + ?
93 94
Select one:
a. alpha emission
b. beta migus emission
c. positron emission
Answer:
beta minus emission
Explanation:
Beta radiations:
Beta radiations are result from the beta decay in which electron is ejected. The neutron inside of the nucleus converted into the proton an thus emit the electron which is called β particle.
The mass of beta particle is smaller than the alpha particles.
They can travel in air in few meter distance.
These radiations can penetrate into the human skin.
The sheet of aluminum is used to block the beta radiation
²³⁹₉₃Np→ ²³⁹₉₄Pu + ⁰₋₁e
The beta radiations are emitted in this reaction. The one electron is ejected and neutron is converted into proton.

If the wavelength of light will cause electrons to be removed from the metal (creating the photoelectric effect). What is the effect of doubling the photon flux of light?
Answer:
The number of photoelectrons are increased
Explanation:
According to Albert Einstein, when light falls on a clean metal surface, electrons are ejected from the clean metal surface. This is known as photo electric effect.
The kinetic energy of the emitted photoelectron depends on the energy of the incident photon and the work function of the metal. If the energy of the incident photon is less than the work function of the metal, photoelectric effect does not occur.
Below a given threshold frequency or wavelength called the threshold frequency or threshold wavelength photoelectric effect does not occur.
However, doubling the photon flux of light doubles the intensity of the light. This only leads to increase in the number of photons and have nothing to do with the energy of the emitted photoelectrons.

What type of elements make up ionic bonds?
Ionic bonds are formed between ionic compounds, Ionic compounds are formed when metals join with nonmetals.
What are ionic bonds?Ionic bonds are electrostatic bonds that are formed between metals and nonmetals. It is an electrostatic attraction between oppositely charged ions in a chemical compound.
These bonds are formed when two or more atoms lose or gain electrons. An example of ionic bonds can be seen in the NaCl compound.
Na⁺ + Cl⁻ = Na⁺Cl⁻
NaCl is formed by the joining of oppositely charged elements. They constitute salt. Salt is made up of ionic compounds, so it easily dissociates into sodium and chloride when mixed in water.
Thus, ionic compounds are created when metals combine with nonmetals, and these combinations result in the formation of ionic bonds.

4. Describe the landforms created at a subducting plate boundary and those created
at a convergent plate boundary between two continental plates. Explain why the
landforms are different.
Answer:Plate Tectonics : Different Plate Boundaries Create Different Landforms and ... Plate Boundary: CONVERGENT ... As the MORE DENSE oceanic plate (OP) subducts under ... Illustration of what is happening ... Two continental plates (CP) move away from each other ... Sea Floor spreading occurs at these mid-ocean ridges.
Explanation:
The landforms created in the subducting plate boundary are mid ocean ridges, fold mountains and islands. Volcanoes and earth quakes are common in these regions.
What is convergent boundary?Plate boundaries are regions of intersections between two tectonic plates. There are three different type of plate boundaries, namely convergent boundaries, divergent boundaries and transform boundaries.
In convergent plate boundaries, two tectonic plates moves close to each other and converge. These plate boundaries gives rise to different types of land forms such as fold mountains, islands etc.
Earthquakes and volcanoes are common in convergent plate boundaries. These type of plate movement is caused by the convection currents in the mantle.

d. None of the above
Answer:
c
Explanation:
Diagram C represents active transport which is a type of facilitated diffusion.
What is diffusion?
Diffusion is defined as the process of movement of molecules which takes place under concentration gradient. It helps in movement of substances in and out from the cell.The molecules move from lower concentration region to a higher concentration region till the concentration becomes equal.
There are 2 main types of diffusion:
1) simple diffusion-process in which substances move through a semi-permeable membrane without the aid of transport proteins.
2) facilitated diffusion- It is a passive movement of molecules across cell membrane from higher concentration region to lower concentration.
There are 2 types of facilitated diffusion one is osmosis and dialysis.

Which of the following best describes the difference between the mass of a balloon and the mass of a bowling ball?
Answer:
Explanation:m
At 1 atm and 300 K, this gives n/V = 0.0406 mol/l. For air, which has a molar mass of 29.0 g/mol, this gives a density of 1.18 g/l. Helium, which has a mass of 4.00 g/mol, has a density of 0.164 g/l. Thus, a one-liter balloon of helium can lift a mass of (1.18-0.164) = 1.02 g. In science, the standard unit of mass is the kilogram (kg). A bowling ball has a mass of about 5 kilograms. Bowling ball weights range from 6 lbs. To 16 lbs. in most cases males will use weights ranging between 12 lbs. and 16 lbs. You might calculate volume using the sphere's radius, circumference or diameter. You can also submerge the sphere in water to find its volume by displacement. Once you know the volume, you can multiply by the density to find the mass.
