Answer:
What process will you use to recover salt which has dissolved in water?
Explanation:
You can boil or evaporate the water and the salt will be left behind as a solid. If you want to collect the water, you can use distillation. This works because salt has a much higher boiling point than water. One way to separate salt and water at home is to boil the salt water in a pot with a lid.

Which THREE choices describe how DNA and RNA lead to the expression of information within the cell?
Answer:
Replication, Transcription, and Translation
Explanation:
Replication, Transcription, and Translation are the three main processes used by all cells to maintain their genetic information and to convert the genetic information encoded in DNA into gene products, which are either RNA's or proteins, depending on the gene.
How would a mutation increase genetic variation?
Answer:
DNA mutation causes genetic variation by altering the genes of individuals in a population. Gene flow leads to genetic variation as new individuals with different gene combinations migrate into a population.
The flow of individuals in and out of a population introduces new alleles and increases genetic variation within that population. Mutations are changes to an organism’s DNA that create diversity within a population by introducing new alleles.
Why can a population evolve but an individual cannot?
A. An individual's genotype is fixed at the time of fertilization.
B. An individual's genotype changes during its lifetime.
C. An individual is the product of recombination.
D. An individual cannot pass changes in
genes to offspring.
Answer:
B. An individual's genotype changes during its lifetime.

Which of the following best describes how crossing over occurs during meiosis?
During prophase I, homologous chromosomes are lined up and pulled apart to opposite poles.
During prophase II, sister chromatids trade places with each other before metaphase begins.
During prophase I, segments of chromatids are exchanged between homologous chromosomes.
During prophase II, spindle fibers begin to form, attaching chromosomes together.
During prophase I, segments of chromatids are exchanged between homologous chromosomes.
What is crossing over?Crossing over is the exchange of chromatid segments between homologous chromosome pairs during the early stages of meiotic division.
Crossing over occurs after the pairing of chromosomes to form tetrads at prophase I of meiosis I.

Among evolutionary mechanisms, there can be mentioned non-random matings (1 and 8) , mutations (3 and 6), genetic drift (2, 4 and 5), and genetic flow (7).
What are evolutionary mechanisms?These are different mechanisms that change allelic frequencies and genotypic frequencies conserning the expected ones if populations were under Hardy-Weinber equilibrium.
When these mechanisms are going on, populations evolve.
Among them, we can mention,

How long does humans know that long gone animals have been on earth?Explain why or why not?
Answer:
Fossils
Explanation:
By using fossils we can not only know that extinct animals once roamed the planet, but also get an estimate of when they did so. We can use fossils to pin down their location (which we can use to see what might have killed them, resource loss, climate change, human interaction, etc.), to see when they appeared and went extinct (thanks to rock layers and knowledge of geology), and even what may have been in their diets (based on location or.. well, other pieces of evidence, if you know what I mean.) Fossils also give you their size and shape which can help paleontologists determine the type of animal, ex. birdlike, reptile, mammal, etc.

How is information contained within a molecule of DNA?
Answer:
DNA stores biological information in sequences of four bases of nucleic acid.
Explanation:
— adenine (A), thymine (T), cytosine (C) and guanine (G) — which are strung along ribbons of sugar- phosphate molecules in the shape of a double helix.
Answer:
Genetic information is carried in the linear sequence of nucleotides in DNA. Each moleculeof DNA is a double helixformed from two complementarystrands of nucleotides held together by hydrogen bonds between G-C and A-T basepairs.
The operational range of temperature in an incubator is
Explanation:
The operational range of temperature in an incubator is 99 ° to 102 ° F
The operational range of temperature in an incubator varies depending on the type of incubator and the application. However, a typical range is between 35 and 100 degrees Celsius (95 and 212 degrees Fahrenheit). The specific temperature range will be specified in the incubator's manual.
For example, a laboratory incubator used for growing bacteria or cells might have a temperature range of 35 to 55 degrees Celsius (95 to 131 degrees Fahrenheit). An incubator used for hatching chickens might have a temperature range of 37 to 40 degrees Celsius (99 to 104 degrees Fahrenheit).
It is important to note that the temperature range of an incubator should not be exceeded, as this could damage the incubator or the samples being incubated. It is also important to monitor the temperature regularly to ensure that it is within the desired range.
