Answer:
Prometaphase (late prophase)
Explanation:
Mitosis is the kind of cell division in which two genetically identical copies of a cell is formed from a cell. Mitosis comprises of stages which include prophase, metaphase, anaphase and telophase. Each phase is characterized by specific occurrences that all work together to achieve the main goal of forming two daughter cells.
According to this question, PROPHASE stage is the stage characterized by the condensation of chromatids into chromosomes, the disappearance of nucleolus and BREAKDOWN of NUCLEAR MEMBRANE.

Union of haploid and diploid gamete results in a zygote that is
Answer:
Triploid
Explanation:
The process whereby gametes produced by different sexes of the same species of organism come together is called FERTILIZATION. A gamete is said to be HAPLOID (n) if it contains one set of chromosomes while it is DIPLOID (2n) if it contains two sets of chromosomes.
Hence, if an haploid (n) and diploid (2n) gamete unites, a zygote that is TRIPLOID (3n) emerges or forms. A triploid zygote will have three sets of chromosomes i.e. n + 2n = 3n.
The modern cell theory doesn't say
A all living things are multicellular
B cells are the smallest living unit in all organisms
C all cells come from other cells
D all living things are made of cells
Answer:
A
Explanation:
Modern cell theory states: cells are the basic unit of structure and function for all living things, all cells come from preexisting cells, and all living things are made from cells. It does not state that all living things are multicellular, in fact there are plenty of unicellular organisms. Therefore the answer is A.
Burning fossil fuels for energy releases harmful emissions into the air. Which health concern is most likely related to these emissions?
A) Increases in blood cancers such as leukemia
B) Increases in skin disorders from absorption
C) Increases in respiratory illnesses such as asthma
D) Increases in digestive disorders from contaminated food
Answer:
Explanation:
its either c or b sorry if it is wrong
Answer:
C
Explanation:
If the harmful emissions are being released into the air, then the most logical answer would be an increase in respiratory illnesses auch as asthma.
It cannot be B or C because they specify that the disordera come from absorption and contaminated food, respectively.
It is most likely not A either.
What is true of all body cells except sex cells?
Each cell type carries chromosomes and genes that identify it as that specific type of cell. For example, skin cells have different chromosomes and genes than muscle cells.
While each cell in the body contains the same number of chromosomes, each cell type has different genes along those chromosomes.
While each cell type in the body contains the same kinds of genes, they are organized on different chromosomes depending on the cell type.
Each body cell contains the same number and kinds of chromosomes for that organism. The chromosomes contain the same number and kinds of genes for that individual.
Explanation:
Each cell type carries chromosomes and genes that identify it as that specific type of cell. For example, skin cells have different chromosomes and genes than muscle cells.

which one contains many organelles with different functions prokaryotic cell eukaryotic cell
Answer:
Eukaryotic Cell
Explanation:
Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of chromosomal DNA.
Explain why the cell membrane is the brain of the cell, as opposed to the nucleus.
Answer:
because it holds the information needed to conduct most of the cell's functions.
Cell membrane controls the transport of molecules across the cell and its external environment, Thus, it is called as the brain of the cell.
Why is cell membrane important?Cell membrane regulates most of the cellular activities through the property of selective permeability.
It is responsible for maintaining the cellular equilibrium through influx and efflux of ions and molecules.
There are various receptors present on the cell membrane which regulates the vital biochemical processes taking place in the body.
Cell membrane functions in the cell-cell recognition and cell signalling through various receptors.
Cell membrane is important in regulating body homeostasis. It offers the protective environment to the cell.
Control and regulation of activities is processed through brain.
Therefore, cell membrane is considered as the brain of the cell.

Provide an explanation for why the indigo dye did not adhere to the different fibers in your test fabric. You will need to do a little bit of outside research on what chemicals make up some of the fibers. You may also need to do some research on intermolecular forces and why some interactions are stronger than others. Please make your explanation at least 500 words in two or more paragraphs. At least one in-text citation is required along with a list of your source(s) in your preferred citation style (MLA, APA, ACS, Chicago Style, etc.).
Answer:
Due to lack of bonds.
Explanation:
The indigo dye did not adhere to the different fibers because the indigo dye did not make bonds with the fiber, it only attached to it physically for temporary period of time. The reduced state is also necessary for indigo because indigo cannot dissolve in water, but when it is reduced it can soluble and able to get inside a fiber to make physical bond with the fiber. Some interactions are stronger than others because of the presence of strong bond between the two different materials so strong bonding makes the materials to attach with each other for a long period of time or permanently.

2.) Tea Kettle & Mugs - The type of heat transfer here is conduction/convection because...
3.) Lamp - The type of heat transfer here is radiation because...
7.) Toaster - The type of heat transfer here is conduction/convection/radiation because...
9.) Radiator/Heater - The type of heat transfer here is radiation because...
Explanation:
1. a burning candle enits radiation in the form of heat and light, this is because of it emission of energy in rays or waves
2.tea and kettle mugs transfer heat by the actual movement of matter. heat leaves the nug as the currents of the steam and air rise. This also emmits heat to the surrounding area.
3.Radiation refers to the emission of energy in rays or waves. In this, a lamps energy is emmiting rays of heat the expands its heat and light to the surrounding area.
7. the coils in the toaster heat the air which heats the toast. A toaster uses infrared radiation because when you put food in the coild glow red.
9. this is beacuse, low wavelength, non visable infared radiation can carry heat directly from warm objects to cooler objects. It emmits and expands its heat energy to the surrounding area and other objects.
What percent of energy is transferred from the sun to the level indicated? (3 points)
50 percent
100 percent
90 percent
10 percent
Answer:
It can
be explained with the help of ten percent law which
states that only 10 percent of the total energy available
at any trophic level is passed on the higher trophic level .
Most of the energy is lost as heat or is used in the
process of cellular respiration.
