Answer:
The answer to this question is Transport would increase.
Explanation:
The transport would just increase.
In the given area-to-volume ratio, the transport would increase across the cell membrane. The correct option is B.
What is area-to-volume ratio?The surface area to volume ratio is merely the surface area divided by the volume of an entity. It calculates the surface area per unit volume of the object.
The crucial fact is that as the cell size increases, the surface to volume ratio decreases.
If the cell expands beyond a certain size, not really enough material can cross the membrane quickly enough to cater the increased cellular volume.
The surface area divided by the volume is the ratio. This suggests how much surface area is accessible in relation to the size of the cell.
The cell is very large if the surface area to volume ratio is small. If the ratio is large, the surface area exceeds the volume the cell will be small.
Thus, the correct option is B.

A. The mother gave a recessive allele to their child.
B. The father gave two recessive alleles to their child.

The most likely reason(s) a metastatic tumor cell might lose its connection to the basal lamina would be: a change in the integrin proteins from the cell's surface. a change in the cadherin proteins on the cell surface. a change in connexins disrupting gap junctions. All of these choices are correct.
Answer:
A change in the integrin proteins from the cell's surface.
Explanation:
Integrin proteins' principal function is to attach the cell to the basal lamina. Also, they transmit signals from the extracellular matrix to the interior of the cell. A change in the integrin could result in loss of connection between the mutated cell and the basal lamina.
Cadherin proteins connect one cell to another. A change in these proteins will not result in the loss of connection between the metastatic tumor cell and its extracellular matrix. It most likely will affect the communication and adhesion of cells.
A change in connexins will disrupt the communication between cells but not the connection to the lamina basal. Connexins are transmembrane proteins that connect one cell to another with gap junctions that allow the passage of different components from cell to cell.

D. The author fully discusses Americans attitudes towards their jobs and contrasts these attitudes with European attitudes towards vacation.
Explanation:
The author has tried to present the two different attitudes of the people of two different countries on the vacation. The American have different attitudes towards the vacation. They feel excited when there is vacation while the people in European countries prefer a day off rather than long vacations.
What is the final result of genetic drift in populations of
Answer: Genetic drift may result in the loss of some alleles (including beneficial ones) and the fixation, or rise to 100% frequency, of other alleles.Once it begins, genetic drift will continue until the involved allele is either lost by a population or is the only allele present at a particular gene locus within a population. ... Genetic drift can result in the loss of rare alleles, and can decrease the size of the gene pool.
Explanation:
Answer:
decrease the genetic diversity of a population.
Explanation:
Genetic drift describes random fluctuations in the numbers of gene variants in a population. Genetic drift takes place when the occurrence of variant forms of a gene, called alleles, increases and decreases by chance over time.
Genetic drift can cause a new population to be genetically distinct from its original population, which has led to the hypothesis that genetic drift plays a role in the evolution of new species.
Any change in the Relative Frequency of alleles in a population is:
Controlled by more than 2 genes
Controlled by a single gene
The gene pool

A. Fallopian tube
B. Ovary
C. Uterus
D. Cervix
Answer:
C. Uterus
Explanation:
Uterus is the female reproductive system.
What is Female reproductive system?The female reproductive system serves a number of purposes. It aids in sexual reproduction in addition to enabling sexual activity.
You make eggs using your ovaries. During ovulation, these eggs are subsequently moved to your fallopian tube where sperm fertilization may take place. The fertilized egg is then transferred to your uterus, where the lining of the uterus has expanded due to the typical hormones produced during your menstrual cycle, also known as your reproductive cycle.
The fertilized egg can implant into the thicker uterine lining once it's within your uterus and continue to grow there. Your menstrual period causes the uterine lining to shed if implantation doesn't occur.
Therefore, Uterus is the female reproductive system.

Compared to freshwater fishes, marine fishes: drink seawater and produce a large volume of urine. do not drink seawater in an effort to conserve as much water as possible. produce a large volume of dilute urine in an effort to rid their bodies of excess water. tend to gain water by osmosis since their internal salt concentration is higher than that of seawater. tend to lose water by osmosis since their internal salt concentration is lower than that of seawater.
Answer:
The correct answer is - tend to lose water by osmosis since their internal salt concentration is lower than that of seawater.
Explanation:
In freshwater fishes, the body of fishes has a higher salt concentration inside their body than the surrounding water, water enters through the osmosis process. Without any active regulation of this process, fishes would swell and get bigger and bigger. They have specialized cells called chloride cells in gills to take ions from water as they do not have kidneys.
In contrast, the marine fishes have a lower salt concentration in their body than surrounding water of sea or ocean and they lose water continuously and to compensate for this they need to drink water regularly.

A scientist studying the effects of radiation on DNA performs an experiment in which she exposes a sequence of nitrogen bases found in DNA to radiation. The DNA before and after the radiation is shown below.
Use the evidence to determine whether a mutation has occurred, and if so, interpret that mutation in the answer sheet provided
Before Exposure: ATCGTCA; After Exposure: ATTCGTCA
A. No mutation has occurred to the DNA sequence.
B. A nitrogen base has been deleted from the DNA molecule.
C. A nitrogen base has replaced another nitrogen base in the DNA molecule.
D. A nitrogen base has been added to the DNA molecule.
Answer:
D. A nitrogen base has been added to the DNA molecule.
Explanation:
You can see that the sequence for the nitrogen bases are in the exact same order after the exposure, this rules out A. You can count how many bases there are, 7 before and 8 after so it cannot be B. Lastly, given that they are in the same order as were before and that a base has been added, you can see that no bases were replaced (so not C) and that D is your answer.

With respect to climate change and natural selection acting upon a population of one species of frog in a tropical rain forest, mutations of DNA sequences of the frog genome that are inherited by offspring It is estimated by a wide body of scientists that in recent decades we have begun another mass extinction event on Earth. Amphibians in particular have been in decline, sometimes due to climate change, and they therefore provide a possible early sign of dramatic biodiversity change to come. With respect to climate change and natural selection acting upon a population of one species of frog in a tropical rain forest, mutations of DNA sequences of the frog genome that are inherited by offspring may have no effect at all, be beneficial, or be harmful. will primarily be harmful. will only speed the decline and extinction of the species. could either be beneficial or harmful.
Answer:
be beneficial.
Explanation:
Mutations of DNA sequences of the frog genome that are inherited by offspring will be beneficial for the frog because this mutation in the genetic makeup of frog provides resistance in this new environmental conditions. This mutation occurs due to the exposure of cell's DNA to the environmental factor which gives benefit to the organisms to survive different condition which can't tolerate by their parents so this mutation is beneficial for that offspring of frog.
