Explanation:
A population of insects became divided when a flood created a lake in the middle of the original population. After many generations, the divided populations differ from each other in several traits such as wing color. Which process likely occurred
Answer:
the process is called allopatric speciation
Explanation:
when two organism separate each other by a geographical barrier or gepgraphical separation (because of flood) it is likely that the two organisms will evolve another certain characteristics.
Mendel determined that for a given character(i.e. pea seed shape) an individual has two factors that these can exist in two forms (R or r). Today we would describe R and r as being:______.
a. different alleles of the seed shape gene.
b. different genes of the seed shape locus.
c. different genotypes of the seed shape character.
d. different loci of the seed shape gene.
Answer:
a. different alleles of the seed shape gene.
Explanation:
Mendel crossed different varieties of pea plants and he observed how phenotypic traits passed to the progeny. From these experiments, Mendel formulated the 'First Law of Segregation', where he observed that traits may exist in pairs that segregate (separate) at meiosis. During meiosis, i.e., gamete formation, these two factors separate from each other, thereby each gamete has the same probability of receiving either factor. Nowadays, we know that these two factors represent two different gene variants or 'alleles' for a given gene locus. Alleles can be classified into dominant or recessive as in the example above described, where the R factor (round) dominates on the r factor (wrinkled) to determine the seed shape.

2) People who are tune deaf are unable to follow a rhythm. Scientists have evidence that
tune deafness can be genetic. The pedigree below traces the inheritance of tune deafness
in a family. Individuals in the pedigree are numbered.

Scientists have analyzed the inheritance patterns for tune deafness and have
concluded that tune deafness is caused by an autosomal dominant allele, T.
a. Provide evidence from the pedigree that conclusively shows that the tune
deafness allele is autosomal dominant, not autosomal recessive. Explain your
reasoning.
b. Identify the genotypes of individuals 5 and 6, and then draw the Punnett square
for the cross of these two individuals.
c. Compare the expected percentage of each phenotype of the offspring from the
cross in part (b) with the actual percentage of each phenotype observed in the
children of individuals 5 and 6
Answer:
There's no pedigree
Explanation:
Sorry, I couldn't comment. You can delete this answer or I can edit this answer later when you edit the question to put a picture of the pedigree
Can someone help me with this bio question plss!!!!!!!!
Answer:
it says that plants are the main source of nutrients and energetic materials and when the cow feed on them, it consumes some of the benefits that we miss when we eat beef
Answer:
Question 6: The answer is the energy, because it collects more energy than the cow. When the cow eats plants, the energy from the plant decreases leaving the cow with only little amount.
Question 7: I agree, Because plants holds way more nutrients and energy than meat. I could support that by saying when a herbivore eats from a plant, It only recieves 10%.

Place the steps of constructing a genomic library in order. I. Digest phage with restriction enzyme. II. Lyse cells of interest and precipitate DNA. III. Introduce constructs via transformation into competent E. coli cells. IV. Perform ligation reaction with genome fragments and phage. V. Digest genomic DNA with restriction enzyme.g
Answer:
The correct answer is -
II: lyse cells of interest, precipitate DNA
V. Digest (cut) genomic DNA with restriction enzyme
I. Digest (cut) phage (chromosome) with restriction enzyme so can ligate in the gene in next step!!
IV. Perform ligation (glue plasmid in!) reaction with genome fragments and phage.
III Introduce constructs via transformation into competent E. coli cells.
Explanation:
The total collection of the genomic DNA of an organism is known as the genomic library of the particular organism. In this library, the genomic DNA is inserted and stored in identical vectors.
The genomic library construction involved some major steps that are:
- Extract and purify DNA - lysing and separating the desired DNA of interest.
- Digest the DNA with a restriction enzyme - breaking or digesting DNA into fragments with restriction enzymes
- cut phage (chromosome) with restriction enzyme
- Insert the fragments of DNA into vectors
- introduce these recombinant a host bacterium by transformation, creating a DNA library.

Grabbing a handful of mixed candy out of a bowl.
Explanation:
For all other options you are choosing specific items... such as a book from the library, or choosing items written on your grocery list, or choosing what to pack for lunch. Bycatch in fishing refers to catching extra fish, other than what you are selecting for. By grabbing a handful of mixed candy from a bowl you are not selecting for a specific 'fish'.
How was osmosis used to stop Clark's seizures?
Answer:
after Clark was treated with a hypertonic solution? increased Na concentration in matrix of brain caused water from blood to move in to the brain which increased the matrix pressure. Pressure caused the neuron firing rate to increase which increased the likelihood of seizures.

A student looks at the daughter cells that result from a process of cell division. Which evidence would support that the process is meiosis? A. The daughter cells are larger than the parent cell B. The daughter cells are the same size as the parent cell C, the genetic material in the daughter cells is the same as in the parent cell D. The genetic material in the daughter cells is different than in the parent cell
Answer: C
Explanation: When daughter cells divide, they always pick up most of the genetic materials/features that the parent cell have.

Which step in the Gram stain is the critical step in differentiating Gram negative cells from Gram positive cells?
Answer:
The rapid decolorization with ethanol or acetone
and counterstaining with safranin
When a decolorizer such as alcohol or acetone is added, it interacts with the lipids of the cell membrane. A gram-negative cell loses its outer lipopolysaccharide membrane, and the inner peptidoglycan layer is left exposed: when safranin is added they will turn red. Conversely, gram-positives retain the Cristal violet and will color in purple

A woman and her baby are on a TV talk show to determine whether or not a particular man is the father of the child. Mom is blood type O and the baby is blood type B. The potential dad is blood type A. Is it true or false that he is the father?
Answer:
No that is not the father
Explanation:
The fathers blood would have to be type B. Type A is dominate to O and co-dominate to B so you get AB blood, type B blood is dominate to O blood. So if the mom has to be OO to show O blood and the father has to be AA blood because he isn't AB or AO, which could make the baby AO or OO blood. Since none of this is true the "TRUE" father would have to have AB, BB, or Bo blood.
