select the cell cycle impairments that you predict would lead to cancer. recall that cancer arises from unregulated, repeated cell divisions. choose all that apply.
Answers
Cancer cells can arise in a variety of ways, the most common, however, tends to be genetic mutations.
Genetic mutations can occur during the life of a cell due to outside factors such as:
The food we eatThe environment we expose the cell toThe substances that touch the cell (e.g skin cells)That being said, the most common time for a genetic mutation to take place is during cellular division. During this time the DNA that encodes the cells is duplicated. Genetic mutations in this DNA sometimes cause the elimination of programmed cell death.
Programmed cell death is what tells a cell when it should stop growing and dividing. This is a regulatory function designed to keep the number of cells at a balance, growing only when needed. As this cell multiplies, this produces an increasing number of cells that will not die. The accumulation of these cells is referred to as cancer.

name three ways that you can explore specific genes to see if they would make good barcodes for species identification.
Answers
The barcode gene sequences should show less intraspecific gene variation than interspecific variation, contain conserved flanking regions and have a short length.
The three most important constraints to explore the suitability of a nucleotide sequence in order to be used as a DNA barcode for taxonomic identifications are:
Barcode gene sequences show less genetic variation within species (intraspecific variation) than between species (interspecific variation).Barcode sequences also show conserved flanking regions in order to be amplified in all species to be identified/categorized.Barcode sequences have short lengths due to technical constraints (amplification by PCR is ideal no more than 1000 base pairs).For example, in animals, an excellent barcode gene sequence used for taxonomic identification is the Cytochrome Oxidase I (COI) gene because this sequence can be used across the evolutionary spectrum.

It is constant if the planet moves at a constant speed.
O It increases as the planet moves away from the sun.
O It is constant for equal times.
OIt increases as the planet approaches the sun.
Answers
Answer: It is constant for equal times
Explanation: Just did the assignment
According to Kepler's second law of motion it is constant for equal times. The correct option is C.
What is Kepler's law?Kepler's laws of planetary motion, published between 1609 and 1619 by Johannes Kepler, characterize the orbits of planets around the Sun.
The speed of a planet in an elliptical orbit around the Sun is described by Kepler's second law of planetary motion.
It states that a line drawn among both the Sun as well as the planet shuffles equivalent regions in equal amounts of time.
As a result, the planet's speed increases as it approaches the Sun and declines as it fades away from it.
Kepler's laws of planetary motion represent a watershed moment in the transformation from geocentrism to heliocentrism.
They establish the first quantitative link among the planets, together with Earth. They also represent a time when the important questions of the day were changing.
Thus, the correct option is C.

Something that may make this sustainable is to remove food from there, or to add more animal species, particulary slightly invasive species that can eat the plants, and fast.
Oops didn't understand at first, yes this will make it more sustainable
Explanation:
To solve this we must be knowing each and every concept related to ecosystem. Therefore, an environment with a large variety of plant and animal species is the correct option.
What is ecosystem?An ecosystem is generated through the interaction of all life forms with each other as well as with the chemical and physical features of their surroundings, all of which are linked by the energy flow. It includes all of the living organisms in a given region in addition to their non - living things surroundings such as air, water, and sunshine.
Humans depend on ecosystems to meet their fundamental requirements. Ecosystems sustain us by providing safe drinking water as well as nutritious food. They supply raw materials for our clothes, housing, transportation, and energy needs. An environment with a large variety of plant and animal species is more sustainable ecosystem.

Mannitol salt agar (MSA) only allows the growth of halophiles. Among the halophiles, mannitol fermenters release acid that turns the pH indicator yellow; mannitol nonfermenters leave the medium red. Onto MSA you inoculate a halophilic mannitol fermenter, a nonhalophilic mannitol fermenter, and a halophilic mannitol nonfermenter. Thus, the medium is acting as a __________ medium.
Answers
Mannitol salt agar can act as both a selective and differentiating medium. A selective medium is one in which inhibits the growth of a particular organism, and allows others to thrive in said conditions. In this case, MSA favors halophilic organisms. MSA is also a differentiating medium because of the mannitol content. Mannitol is a sugar and mannitol fermenters, like s. saprophyticus, use mannitol and release acid as a byproduct. The pH indicator within the agar changes from red to yellow.

what determines the primary structure of a dna molecule?
Answers
Answer:
I would go with the sequence of the bases in the nucleic acid chain
The sequence of nucleotides defines the primary structure of DNA and RNA where the nucleotides are linked to the oxygen on the 5' carbon of one through the phosphodiester bond linking to the oxygen on the 3' carbon of the other.
What is DNA?Deoxyribonucleic acid is a polymer which is made up of two polynucleotide chains that coil around each other to carry the genetic instructions for growth, function, development, and reproduction in all known organisms and many viruses. DNA and RNA are nucleic acids.
DNA is made up of chemical building blocks called nucleotides which are building blocks made up of three parts:
1. A phosphate group
2. A sugar group
3. One of four types of nitrogenous bases i.e. adenine (A), cytosine (C), guanine (G), and thymine (T)
To form a strand of DNA, nucleotides are linked in chains, alternating between phosphate and sugar groups.
Thus, the sequence of nucleotides defines the primary structure of DNA and RNA where the nucleotides are linked to the oxygen on the 5' carbon of one through the phosphodiester bond linking to the oxygen on the 3' carbon of the other.
