Below is an inaccurate (false) statement. Explain two distinctly different reasons why it is incorrect. Be specific, and use rel
Alisiya [41]

Answer:

The given statement is false, as some of the fruits like a banana do not contain seeds as they get propagated through the offsets. The development of banana takes place without fertilization, that is, via the procedure of parthenocarpy. All the fruits are also not sweet in taste like lemon is a fruit, which is sour in taste. Thus, all the fruits are sweet is also incorrect.

Filtrate is formed as fluid is forced through the walls of the glomerulus and
Goryan [66]

Answer:

initially, collects in the structure indicated by the letter B

Explanation:

Filtrate is formed as fluid is forced through the walls of the glomerulus and, initially, collects in the structure indicated by the letter B.

Urine formed by a kidney collects in the renal pelvis before being drained from the kidney by the urethra and transported to the urinary bladder.

The process by which glomerulus filtration occurs is called renal ultrafiltration. The force of hydrostatic pressure in the glomerulus (the force of pressure exerted from the pressure of the blood vessel itself) is the driving force that pushes filtrate out of the capillaries and into the slits in the nephron.

Does geographic distance between salamander populations increase their reproductive isolation? To answer this question, research
Nataly_w [17]

Question: Does geographic distance between salamander populations increase their reproductive isolation?  To answer this question, researchers studied populations of the dusky salamander (Desmognathus ochrophaeus) living on different mountain ranges in the southern Appalachian Mountains.  The researchers tested the reproductive isolation of pairs of salamander populations by leaving one male and one female together and later checking the females for the presence of sperm. Four mating combinations were tested for each pair of populations (A and B)—two within the same population (female A with male A and female B with male B) and two between populations (female A with male B and female B with male A).  The proportion of successful matings for each mating combination was measured. For example, when all the matings of a particular combination were successful, the researchers gave it a value of 1; when none of the matings were successful, they gave it a value of 0. Then the researchers calculated an index of reproductive isolation that ranged from 0 (no isolation) to 2 (full isolation). The reproductive isolation value for two populations is the sum of the proportion of successful matings of each type within populations (AA + BB) minus the sum of the proportion of successful matings of each type between populations (AB + BA).

The table (Figure 1) provides data for the geographic distances and reproductive isolation values for 27 pairs of dusky salamander populations.

Part A - Understanding experimental design

What hypothesis did the researchers test in this study?

Answer:

"Reproductive isolation increases with geographic distance between dusky salamander populations"

Explanation:

The mechanisms of reproductive isolation are a assemblage of evolutionary mechanisms, behaviors and physiological procedures dangerous for speciation. They avert followers of dissimilar types from manufacturing offspring, or confirm that any offspring are germ-free. While in allopatric speciation the reproductive isolation is resolute superficially by the spatial isolation of populations, during sympatric speciation specific groups of persons create distinct mating organizations with self-like persons while distribution the similar home with the rest of the unique inhabitants.

Why is the use of embryonic stem cells controversial?
Brrunno [24]
Stem cell therapies are not new. Doctors have been performing bone marrow stem cell transplants for decades. But when scientists learned how to remove stem cells from human embryos in 1998, both excitement and controversy ensued.

The excitement was due to the huge potential these cells have in curing human disease. The controversy centered on the moral implications of destroying human embryos. Political leaders began to debate over how to regulate and fund research involving human embryonic stem (hES) cells.

Newer breakthroughs may bring this debate to an end. In 2006 scientists learned how to stimulate a patient's own cells to behave like embryonic stem cells. These cells are reducing the need for human embryos in research and opening up exciting new possibilities for stem cell therapies.
