Answer:
The Meiosis Cell Cycle
Explanation:
Cell cycle is the process if cell division. The end product of cell cycle is two genetically identical daughters cells produced by cell division.
What is cell cycle?Cell cycle is the process occurring through different stages by which a cell divides to form its daughter cells. Various enzymes have significant roles in cell cycle.
A large number of DNAs in the chromosome of a cell undergo division where, the double stranded DNA separate and and each strand forms two new DNAs.
Therefore, at the end of a cell cycle through proper cell division, two genetically identical daughters cells are produced.

Many commercial greenhouses use heaters that burn gas or oil because?
It promotes the movement of air as heat circulates and rises, helping to reduce excess humidity that could harm crops. This efficient system can not only reduce fuel costs by up to 10%, but it warms the medium and root zone before rising to heat the crops and the air above, creating ideal growing conditions.
The heating of a greenhouse is traditionally done by using a central gas boiler which heats water that is distributed into the greenhouse. ... These hot air heaters run on either natural gas, petroleum and diesel. This direct combustion generates the by-product carbon dioxide, which can be advantageous for plant growth.

Group of answer choices
genetic material is exchanged between sister chromatids, resulting in new combinations of alleles.
sister chromatids from each homologous chromosome of a tetrad are exchanged, resulting in new combinations of alleles.
genetic material is exchanged between nonsister chromatids, resulting in new combinations of alleles.
nonsister chromatids from each homologous chromosome of a tetrad are exchanged, resulting in new combinations of alleles.
Answer:
genetic material is exchanged between nonsister chromatids, resulting in new combinations of alleles.During crossing-over, the genetic material is exchanged between non-sister chromatids, resulting in new combinations of alleles. Thus, the correct option is C.
What is Crossing-over?Meiosis is the cell division in which crossing-over takes place. Crossing-over results into formation of recombinants with genetic material which is different from the parental cells. Crossing-over takes place in the pachytene stage of prophase I of Meiosis I. This is responsible for the production of variations in the organisms.
Crossing over or chromosomal crossover is the exchange of genetic material during the sexual reproduction between the non-sister chromatids of two homologous chromosomes which results in recombinant chromosomes.
Therefore, the correct option is C.

How could the aquifer around the Los Angeles are in California be susceptible to an impact by a Tragedy of the Commons?
Answer:
Due to over-pumping of water.
Explanation:
The aquifer around the Los Angeles are in California could be susceptible to an impact by a Tragedy of the Commons because the people used more water than the aquifer receives. The excess use of water from the aquifer through the well causes depletion of water which results in the shortage of water to fulfill the needs of existing population so it is wise to use water efficiently and used lower or equal water the aquifer receives in order to maintain level of aquifer.

HELP QUICK . Come up with an explanation as to why there is some advantage to a dark mouse in a lighter habitat
but not lighter mice in darker environments ?
The darker mouse could hide in the shadows easier where hunters won't look and a lighter mouse in. darker habitat would stand out more than anything around it and result in it being easy prey.
I hope this helps ^^
The advantage to a dark mouse in a lighter habitat but not lighter mice in darker environments is predators could more easily spot the dark mice on light sand.
What are the characteristics of predators?Predators are organisms that hunt and kill other organisms for food. The organisms that are consumed by the predators are known as the prey. Predators can be carnivores and omnivores.
There are four commonly recognized types of predation: (1) carnivory, (2) herbivory, (3) parasitism, and (4) mutualism. Each type of predation can by categorized based on whether or not it results in the death of the prey.
Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit. The words "predator" and "prey" are almost always used to mean only animals that eat animals, but the same concept also applies to plants.

Which statement best predicts why a cell's progression through the cell cycle might be halted by the G1/S checkpoint?
Answer:
The missing options are:
A. Spindle fibers have not correctly attached to chromosomes.
B. Damage occurred to DNA when it was being copied in G1.
C. There are not enough nucleotides available to construct new DNA.
D. Proteins necessary for M phase of the cell cycle have not been produced.
The correct option is C.There are not enough nucleotides available to construct new DNA.
Explanation:
During the G1 phase, the cell grows in size since it prepares its organelles and molecule combinations for the next phase of the cell cycle, the S phase. Before the cell transitions to the S phase, it has to pass through a checkpoint that makes sure that there are no mutations, it has grown enough, and has the necessary molecules for the next phase, which is the synthesis of DNA. If there are not enough nucleotides, the cell will not be able to synthesize new DNA in the S phase, so the checkpoint stops the cells from moving to this phase till it has all the necessary things to do it.

¿Cuál de los siguientes enunciados NO forma parte de la teoría celular propuesta por Schleiden y Schwann, y con aportes de Virchow? * E) Toda célula deriva de otra preexistente D) Todos los seres vivos están formados por células. C) La célula es la unidad de evolución de los seres vivos. A) La célula es la unidad de estructura de los seres vivos. B) La célula es la unidad funcional de los seres vivos.
Answer:
C) La célula es la unidad de evolución de los seres vivos.
Explanation:
La teoría celular fue formulada por Schleiden y Schwann en 1837 a partir de observaciones propias y de información citológica relacionada con la estructura y la función de las células obtenida muchos años anteriores a ellos, especialmente a partir de los aportes de 1-Anton Van Leewenhoek, quien identificó microrganismos vivos mediante sus observaciones con un microscopio, y 2-Robert Hooke, quien observó celdas (de allí el nombre de células) también bajo el microscopio. Schleiden y Schwann postularon que la célula debería ser la unidad estructural y funcional en los seres vivos, la cual debería ser capaz de mantener de modo independiente el estado vital. Posteriormente, en 1855, Virchow aportó una conclusión fundamental: todas las célula derivan de la replicación (división) de células preexistentes. Los virus se consideran una excepción a la teoría celular porque ellos son considerados organismos vivos (aunque esta consideración está sujeta a debate), los cuales poseen un nivel estructural y de organización menor al nivel de una célula. Respecto a este punto, cabe aclarar que los virus son parásitos intracelulares los cuales derivan (descienden evolutivamente) de organismos celulares y por lo tanto es posible asumir a sus orígenes como subproductos de los genomas de las células (es decir, de organismos celulares).
