Answer:
10.5minutes
Explanation:
DRT = 90%
Cells present = 10^6
Autoclaving = 1.5 minutes
Solution:
10^6(1.5)10^5(1.5)10^4(1.5)10^3(1.5)10^2(1.5)10^1(1.5)10^0(1.5)0=10.5
it would take it approximately 10.5 minutes to kill 10^6 of the cells.
If i should stop the heating process at 9 minutes this would have effect on some of the microbes as they are still present with 1 bacterium left which makes it not efficient.

What is the process that occurs when a recipient eukaryote cell accepts DNA gragmets indirectly from the surrounding environment?
Answer:
horizontal gene transfer
Explanation:
Horizontal Gene Transfer (HGT) can be defined as a non-sexual process that enables the exchange of genetic information between genomes. Although HGT mainly occurs between prokaryotic genomes, an increasing number of examples involving eukaryotic host genomes have recently been described. Agrobacterium bacteria are capable of transferring and integrating DNA into the genome of eukaryotic cell hosts by the HGT mechanism. The transference of genetic material via Agrobacterium-mediated transformation is widely used in biotechnology to generate plants with desired genetic sequences. In the last years, it has been shown that various bacterial species including Bartonella henselae Rhizobium etli or even Escherichia coli, are able to genetically transform eukaryotic cells under laboratory growth conditions. The genetic phenomenon of horizontal gene transfer has evolutionary significance since it enables to bypass barriers between kingdoms in order to acquire nucleotide sequences that may eventually have some adaptive advantage. Moreover, the mechanism of horizontal transfer challenges a narrow vision of the eukaryotic genome as a fixed entity.

If the sequence of an mRNA moving through the ribosome has the sequence 5'AUGCCAGCGGAUCGC3', what is the sequence of the polypeptide produced from translating this segment
Answer:
MPADR (methionine-proline-alanine-aspartic acid-arginine)
Explanation:
Translation is the mechanism for which a protein is synthesized from the information encoded in the messenger RNA (mRNA). The mRNA is a single-stranded molecule that consists of a chain of nucleotides, where three-letter combinations of nucleotides 'or codons' specify the order of the corresponding amino acids in the polypeptide chain. The ribosome reads the mRNA by one codon at a time and thus translates this information into a polypeptide, where each codon is specific for one amino acid. In this code, the start codon is AUG (which is read as Methionine), while stop codons can be UAG, UAA, and UGA.

Restriction endonucleases cleave at __________ , which are sequences that read the same, 5 to 3 , on each DNA strand.
Answer:
Restriction endonucleases cleave at DNA (Deoxy ribonucleic acid) which are sequences that read the same, 5 to 3 , on each DNA strand.
Explanation:
RESTRICTION ENDONUCLEASES-: An enzyme that cleaves DNA into fragments at or near unique recognition sites within molecules known as restriction sites is a restriction enzyme, constraint endonuclease, or restrictase. One class of the larger endonuclease group of enzymes is restriction enzymes. Restriction enzymes are typically divided into five groups, which vary in structure and whether their DNA substrate is cut at their location of recognition or whether the locations of recognition and cleavage are different from one another. Both restriction enzymes make two incisions in order to cut DNA, once through each sugar-phosphate backbone (i.e. each strand) of the double helix DNA.
In bacteria and archaea, these enzymes are contained and provide a defence mechanism against invading viruses. Within a prokaryote, in a process called restriction digestion, the restriction enzymes selectively cut up foreign DNA; meanwhile, host DNA is protected by a modification enzyme (a methyltransferase) that modifies the prokaryotic DNA and blocks cleavage. Together, these two procedures form the method of restriction alteration.

Identify the incorrect statement about a single motor unit. Identify the incorrect statement about a single motor unit. Some motor units include as many as 2000 muscle fibers. Fine motor skills depend on the development of small motor units. The more neurons involved, the more powerful the contraction. The smaller the number of muscle fibers, the more precise the movement. Muscle fibers of one motor unit intermingle with the fibers of another motor unit.
Answer:
The more neurons involved, the more powerful the contraction
Explanation:
The motor unit can be defined as the functional unit for muscle contraction, which consists of a motor neuron and the associated muscle fibers it innervates. The number of associated muscle fibers varies depending on the muscle’s ability for contraction. Muscles with a higher number of motor units can modulate force output more finely. The number of muscle fibers per motor unit is inversely proportional to the force that it generates, and while higher is precision, lesser is the size of the motor unit. A higher number of neurons is required for controlling motor units with lesser size, thus being greater the brain's control over the extent of shortening.
The incorrect statement about a single motor unit is that some motor units include as many as 2000 muscle fibers. The correct option is A.
One motor neuron and the muscle fibres it innervates make up a motor unit in most cases. Although a motor unit's muscle fibre count might vary, it is normally significantly lower than 2000.
Depending on the muscle and its purpose, the number of muscle fibres in a motor unit might range from a few to several hundred.
Smaller motor units are linked to more precise motions, whereas larger motor units are in charge of more strong contractions. The size of the motor units affects the level of control and precision of movement.
Thus, the correct option is A.

How do changes in population size relate to environmental conditions?
Answer:
Population size certainly relates to environmental conditions, as more people in a city equate to a higher amount of cars—thus increasing emissions. Additionally, there could be more factory runoff–polluting nearby rivers and waterways.
Population and resource utilization per person determine ecosystem vulnerability. Population expansion increases resource demand, waste, and environmental deterioration.
What are the effects of increase in population on the environment?The hazard to the ecosystem is proportional to human population number and resource consumption per person. Population increase accelerates resource use, waste generation, and environmental degrading.
Through overexploitation, intensive farming, and land fragmentation, it lowers the quality and quantity of natural resources. In regions with significant population pressure, arable land is scarce, resulting in a shortened/eliminated fallow time, a decline in soil fertility, and a decline in farm income owing to farm subdivision.

Can a fossil be created in a few weeks? How long do you think it
takes a dinosaur fossil to form?
Answer:
Fossils are defined as the remains or traces of organisms that died more than 10,000 years ago, therefore, by definition the minimum time it takes to make a fossil is 10,000 years. But, that is just an arbitrary line in the sand – it means very little in terms of the fossilisation process.
Explanation:
Fossils are a record of organisms that lived in the past. are two main categories of fossils: body fossils and ichnofossils. Body fossils are the result of preservation of parts or the entire body of a plant, animal, or microorganism. These are the fossils that people are most familiar with, consisting of skeletons, teeth, shells, carapaces, organisms in amber, petrified wood, plant material, pollen, etc. Ichnofossils (also called trace fossils) are evidence of an organism’s activity. Common ichnofossils are animal footprints and trackways, burrows, traces of plant roots, coprolites (fossil feces), and borings in rocks, bones, wood, shells, or other substrates. The study of fossils provides information about ancient biological communities, and the physiology, behavior, and ecology of organisms.
In conclusion, fossilization at least at the present time, is thought to be a very unlikely process and it is believed that only a very small fraction of organisms that lived in the past became fossils. The majority of these fossils were hard skeletal parts or wood. To become fossilized, organisms must be rapidly buried, preferably in a fine sediment with geochemical conditions that favor the exchange of minerals between the sediment and organic components of the organism, and that exchange of minerals is possible because of dissolved minerals in flowing water. If those conditions occur, fossilization must necessarily be a rapid process of a few hours to a few months if it is to occur before decay destroys any record of the organism. Fossilization does not take thousands or millions of years, but is most likely to occur in catastrophic conditions such as would have existed during the Genesis Flood.
