Answer:
1. lytic/losigenic cycle
2. Restriction enzymes (breaks) and DNA ligase (joins)
3.mitosis (creation of twin daughter cells)
4. mitosis had helped humans with cell growth and repais (and keeps a steady supply of new cells)
Explanation:
it first goes through the lytic cycle where one bacterium inserts it's own dna into a host (human cell) and into the human DNA and it starts multiplying inside human cells in the lysogenic cycle

About 3 million years ago, the Isthmus of Panama (a narrow strip of land connecting North and South America) formed, dividing marine organisms into Pacific and Caribbean populations. Researchers have examined species of snapping shrimp on both sides of the isthmus. Based on the morphological species concept, there appeared to be seven pairs of species, with one species of each pair in the Pacific and the other in the Caribbean. The different species pairs live at somewhat different depths in the ocean. Using mitochondrial DNA sequences, the researchers estimated phylogenies and found that each of these species pairs, separated by the isthmus were indeed each other's closest relatives. The researchers investigated mating in the lab and found that many species pairs were not very interested in courting with each other, and any that did mate almost never produced fertile offspring. Which process led to the formation of the species pairs of Pacific and Caribbean snapping shrimp

Answer:
Allopatric speciation
Explanation:
Allopatric speciation refers to the geographic separation of a continuous genetic background, originating two or more new geographically isolated groups. These divergences of the original population might be related to migration in different directions, extinction of geographically intermediate populations, or geological events. During these events of speciation, emerging new barriers impede genetic flow between groups, as the two new populations that are separated can not get together and mate anymore. These barriers might be geographical or ecological.
Different stages are involved in the allopatric speciation process:
• The emergence of the barrier.
• Interruption in the genetic flow
• Slow and gradual differentiation due to the occurrence of mutations in each population and their accumulation in time.
• Genetic divergence by natural selection and reproductive isolation, impeding the two groups to mate even if the barrier disappears.
• Prezigotic isolation mechanisms favored by selection a secondary contact between the new species occurs.
The Panama isthmus is an example of allopatric speciation caused by an extrinsic geological barrier that interrupted the genetic flow between species driving to genetic changes and reproductive isolation.
Two different groups that evolved in allopatry might meet again in secondary contact if the barrier that separated them, disappears. In the Panama isthmus example, the groups that did mate, could not produce any fertile progeny because of postzygotic reproductive isolation. And the groups that did not mate, were not attracted to each other because of prezygotic reproductive isolation.

Choose the phase of meiosis in column 2 that best matches each event in column 1. - one haploid set of replicated chromosomes at each spindle pole - genetic recombination events take place - shortest stage - aligning of bivalents in the center of a spindle - one haploid set of unreplicated chromosomes at each spindle pole - aligning of monovalents in the center of a spindle - separation of homologous chromosomes - separation of sister chromatids A. telophase II B. anaphase I C. metaphase I D. prophase II E. anaphase II F. telophase I G. metaphase II H. prophase I
Answers
Answer:
H. prophase I → genetic recombination events take place
C. metaphase I → aligning of bivalents in the center of a spindle
B. anaphase I → separation of homologous chromosomes
F. telophase I → one haploid set of replicated chromosomes at each spindle pole
D. prophase II → shortest stage
G. metaphase II → aligning of monovalents in the center of a spindle
E. anaphase II → separation of sister chromatids
A. telophase II → one haploid set of unreplicated chromosomes at each spindle pole
Explanation:
Through the process of Meiosis, a diploid germ cell (2n) divides and originates four daughter cells with a haploid chromosome number (n). Each daughter cell has half of the chromosomes of the original one. Meiosis is completed in two phases. During the first phase, and after replication, occurs the chromosome´s reduction division. During the second phase, the cell suffers a new, not reductive division.
1. In the first phase, Meiosis I:
Prophase I: Chromosomes condensate and became visible. Occurs crossing-over between homologous chromosomes. Crossin-over makes the daughter cells to be genetically different from the original one. Metaphase I: The pairs of homologous chromosomes randomly align in the equatorial plane. Anaphase I: occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. Telophase I: Each of the homologous pairs chromosomes is already in the corresponding poles, and the nuclear membrane forms again in each pole.2. In the second phase, Meiosis II:
Prophase II: Chromosomes condensate again and become visible. Metaphase II: Chromosomes join the spindle apparatus and migrate to the equatorial plane, where they randomly line up. Sister chromatids are holden together until they reach the Anaphase. Anaphase II: Centromeres divide, chromatids get separated, and each of them goes forward an opposite cellular pole. Telophase II: Once in the poles, the chromosomes became lax again, and cytokinesis occurs.
Farmer toon soon wanted to start breeding his plants so that they are resistant to disease while producing more fruit per plant.Which plants should the farmers cross to get the desired (wanted) combination of traits
Answers
Answer:
cultivated plant variety with its wild type variety.
Explanation:
The farmer cross the cultivated plant variety to its wild type which has the characteristics of resistance against diseases. Due to crossing, the offspring produce having resistance against that disease as well as producing high yield. This type of crossing is known as artificial selection in which humans cross two organisms to get the desired characteristics in their offspring so to get a plant with resistance against disease we cross cultivated plant variety to its wild type.

Which of the following correctly describes the arrangement of the phospholipids in the lipid bilayer of the cell membrane? *
Phospholipids line up head to head, so the phosphate heads are separated from water.
Phospholipids line up head to tail, because opposites attract.
Phospholipids line up tail to tail, so the fatty acid tails are separated from water.
Phospholipids line up with no pattern, because they're molecules which move randomly.
Answers
Answer:
Two layers of phospholipids where the outer layer has the hydrophilic heads facing toward the outside of the cell and the inner layer have the hydrophobic tails facing toward the inside of the cell.

what happens directly after metaphase
Answers
Answer:The third phase of mitosis, following metaphase and preceding telophase, is anaphase. Since the sister chromatids began attaching to centrosomes on opposite ends of the cell in metaphase, they're prepped and ready to start separating and forming genetically-identical daughter chromosomes during anaphase.
Explanation:
Answer:
The next phase is anaphase. The chromatids separate at the centromere. The spindle fibers begin to pull them to opposite sides of the cell.
