Bacteria divide by a process called binary fission where one bacterial cell will replicate its
DNA as the cell elongates, then the cell will divide into 2 identical daughter cells. Assuming
favorable conditions, bacteria divide every 20 minutes. If one bacterial cell replicated
according to this condition, how many bacterial cells would one expect to find at the end of
two hours and 20 minutes (140 minutes)?
lol
Answer:
The usual method of prokaryote cell division is termed binary fission. The prokaryotic chromosome is a single DNA molecule that first replicates, then attaches each copy to a different part of the cell membrane. When the cell begins to pull apart, the replicate and original chromosomes are separated.
Various hormones and factors (signal molecules) both influence and encourage mitosis in vertebrate animals. What processes might these signal molecules elicit in cells, and why might this signaling be important to homeostasis for an animal?
Answer:
Mechanisms enabling one cell to influence the behavior of another almost certainly existed in the world of unicellular organisms long before multicellular organisms appeared on Earth. Evidence comes from studies of present-day unicellular eucaryotes such as yeasts. Although these cells normally lead independent lives, they can communicate and influence one another's behavior in preparation for sexual mating. In the budding yeast Saccharomyces cerevisiae, for example, when a haploid individual is ready to mate, it secretes a peptide mating factor that signals cells of the opposite mating type to stop proliferating and prepare to mate (Figure 15-2). The subsequent fusion of two haploid cells of opposite mating types produces a diploid cell, which can then undergo meiosis and sporulate, generating haploid cells with new assortments of genes.

Following the cell division of a eukaryotic cell, the two daughter cells end up with the wrong number of chromosomes. One has one too many chromosomes and the other has one too few. During which phase of mitosis did this error likely occur?
The error most likely occured during the anaphase of mitosis.
MITOSIS:
Mitosis is a type of cell division in which two genetically identical cells result from a single parent cell. Mitotic process occurs in various stages namely: interphase, prophase, metaphase, anaphase and telophase. The chromosomes separate i.e. are pulled apart equally into each daughter cells at the ANAPHASE STAGE. Hence, an error in cell division in which one daughter cell has one too many chromosomes and the other has one too few chromosomes occured specifically in the ANAPHASE STAGE.Learn more at: https://brainly.com/question/3327479?referrer=searchResults

What are 2 pieces of evidence that support the Continental Drift Theory? Explain how they support the theory.
Answer:
Explanation: In the early part of the 20th century, scientists began to put together evidence that the continents could move around on Earth's surface. The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones.
The fit of the continents; the dispersion of ancient fossils, rocks, as well as highlands; and the positions of ancient climatic zones were all evidence for continental drift.
What is Continental Drift Theory?Continental drift was a groundbreaking theory that explained how continents shift position on the Earth's surface.
Alfred Wegener, a geophysicist and meteorologist, proposed the theory in 1912, but it was rejected by mainstream science at the time.
Plate tectonics caused continental drift over millions of years. Plate tectonics also explained how plate movement causes volcanoes and earthquakes, as well as how continent collisions create massive mountain ranges.
Continental drift was demonstrated by the fit of the continents, the dispersion of ancient fossils, rocks, and highlands, and the positions of ancient climatic zones.
Thus, these are the evidences that support the Continental Drift Theory.

What are other factors that could affect reaction time? Research and describe how the peripheral nervous system and the central nervous system work together in reacting to stimuli?
Answer:
Many factors have been shown to affect reaction times, including age, gender, physical fitness, fatigue, distraction, alcohol, personality type, and whether the stimulus is auditory or visual. Sensory neurons convert a stimulus into an electro-chemical signal, which flows the length of the
sensory neuron(s), then through a neuron or neurons of the central nervous system, and then
through the length of the motor neuron(s). Generally, motor neurons will cause a muscle to
contract or a gland to secrete a substance. Reactions that involve only the receptor, the spinal
cord, and the effector, are faster than those which involve processing in the brain. Reactions
which only travel to, through, and from the spinal cord are often called spinal reflexes or cordmediated reflexes; withdrawing one’s hand from a hot stove is an example of such a reflex.
In ‘simple reaction time’ experiments, there is only one stimulus and one response. Catching a
dropped stick, or hitting a button when a light changes are examples.
In ‘recognition reaction time’ experiments, there are symbols to respond to and symbols to be
ignored. There is still only one correct stimulus and one response. An example would be
catching a dropped stick with a word cue, while having to ignore other spoken words which are
not cues.
In ‘choice reaction time’ experiments, there are multiple stimuli and multiple responses. The
reaction must correspond to the correct stimulus. Typing a letter which matches a printed letter
prompt is an example of this type of experiment.

This type of inheritance pattern shows BOTH traits in possible offspringand is not a blending or intermediate
phenotype.
O a. incomplete dominance
O b. dominant pattern inheritance
O c. complete dominance pattern inheritance
O d. codominance
Answer:
The correct answer is - d. codominance.
Explanation:
Complete dominance is the pattern of inheritance where one allele masked the other allele completely in a heterozygous condition. Incomplete dominance is a pattern of inheritance where both the alleles blend or form intermediate phenotype in heterozygous condition.
The codominance pattern of inheritance is similar to the incomplete dominance but instead of making a blend of both alleles, it expresses both alleles together in patches or pattern.
The type of inheritance pattern that shows BOTH traits in offspring and is not a blending or intermediate phenotype is CODOMINANCE.
In genetics, codominance refers to the phenomenon by which both parent phenotypes for a given trait are simultaneously expressed together in the offspring.
Conversely, incomplete dominance occurs when the phenotypes of the two parents are mixed in the offspring in order to create a new intermediate phenotype.
Finally, complete dominance refers to the inheritance pattern by which a dominant allele completely masks the expression of the recessive allele in offspring.
In conclusion, the type of inheritance pattern that shows BOTH traits in possible offspring and is not a blending or intermediate phenotype is CODOMINANCE.

When crude oil is distilled, it is separated into categories. What are those categories characterized by?
Answer:
Differences in their boiling points
Explanation:
When crude oil is distilled and separated into categories, the categories are characterized by the differences in their boiling points.
At different boiling points, each of the fraction will separate out.
Crude oil is made up of different fractions of hydrocarbons. As the chain length of the hydrocarbon increases, the volatility reduces and boiling point increases. Components with short carbon lengths rises out from the column first and are cooled and extracted. The categories are thereby, classified based on differences in their boiling points.Which of the following is the most efficient substance to complete cellular respiration?

Answer:
Sugar
Explanation:
The correct answer would be sugar.
Respiration generally involves the metabolic breakdown of carbohydrates to generate energy (in the form of ATP). It is a multi-step process that can summarily be represented by the equation below:
[tex]C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + energy[/tex]
As a rule of thumb, the higher the respiratory quotient of a substrate, the higher the energy that will be generated if such a substrate is utilized for respiration. By definition, the respiratory quotient of a substrate is the ratio of carbon dioxide to oxygen produced or consumed to breakdown the substrate.
Carbohydrates are known to have the highest respiratory quotient while other molecules follow in varying degrees. Other substances apart from carbohydrates have to undergo one or two metabolic processes before they can enter the respiratory pathway, thereby reducing their efficiencies when compared to carbohydrates.
