Why do so many more people have brown eyes then blue eyes
An experiment similar to the 1952 Hershey and Chase experiments was done in which radioisotope 35S was added to a bacteriophage replicating within its bacterial host. The new phage particles were carefully isolated and used to infect fresh bacterial cells and no radioisotopes were utilized. Based on this information, where would you expect to find the 35S radioisotope immediately after infection
Answer:
inside the phage ghosts outside the bacterial cells.
Explanation:
According to Hershey & Chase- Experiments, the radioisotope 35S is frequently associated with protein since sulfur is a protein component. The radioactive sulfur is absorbed into the protein coat because it already contained sulfur (35S). The radioactive marker 35S was integrated into the Bacteriophage protein coat and remained as phage ghosts outside the bacterial cells.
why does secondary consumers cannot digest the bones of their prey
Answer:
The conclusion to be drawn from the fact that secondary consumers do not digest the bones of their prey is that energy used to create bone mass often does not travel farther up the food chain . Explanation: ... No energy is required to form bones .

If more snakes moved into this environment, then
A. the number of rabbits would go up.
B.the number of grasshoppers would go up.
C. the number of toads would go up.
D. The number of hawks would go up.
NO LINKS AND DO NOT ASK A QUESTION UNDER MY QUESTION ❗❗❗
Answer:
B. The number of grasshopers would go up.
Explanation:
A. is incorrect because it would decrease
C is incorrect because it would also decrease
D is incorrect because snakes dont eat Hawks, but Hawks eat them
B is correct because since snakes would eat the toads, there would be no toads eating grasshoppers

Answer:
C
Explanation:
Calculate the number and percentage of eukaryotic species that are still to be formally described?
the number and percentage of eukaryotic species that are still to be formally described is to be beauty
Eukaryotic organisms are species that have defined nucleus and membrane limited organelles. Total 11% or 250,000 are described while 97% or 8490000 are yet to be described.
What is the population of the eukaryotes?Eukaryotes are the largest and the most dominating species that includes kingdom plants, animals, fungi and protists. A total of 8.74 million eukaryote species on Earth are present from which only 250,000 are described.
Eukaryotes are the species that are well-defined organisms that contain the genetic material enclosed within the nuclear membrane and the organelles are also enclosed.
With new discoveries and findings, many new species are described that are grouped into one of the kingdoms based on their properties and features.
Therefore, 8.74 million eukaryote species are present on Earth.

Several human populations spread throughout the Sahara desert have multiple mutations in Gene R that confers heat tolerance. Independently, a small population of humans in the Mojave desert of California have a unique mutation in Gene Z that also confers heat tolerance. The evolution of adaptation of heat tolerance across all of these populations would be considered an example of _________
Answer:
Variation
Explanation:
Migration into a population from other populations with varying gene frequencies, evolution, or adaptation of heat tolerance is a cause of variation. The allele frequency of the resulting hybrid population would be right in the middle of its original value and the donor population's frequency. In tropical and subtropical ecosystems (Sahara deserts), high temperatures are a significant restriction to human population productivity; they induce morphological and physiological modifications at all times, resulting in significant yield losses but the ability and evolution of human species to cope in this region is as a result of variation.
