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.

b) What is DNA? What is a Gene?
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.
Scientists use computer models to study complicated events and to
a. perform experiments
b. state theories
c. change theories and laws
d. make predictions
Answer:
The correct answer is - d. make predictions.
Explanation:
Computer models are scientific models that help in analyzing complex systems. Scientists use these to analyze data and on the basis of these data computer models are able to predict the outcome of the problem or can tell what will happen in the future.
These are very helpful in complex systems and are made on the basis of the data collected and are the basis of the models. Weather forecast can be predicted on the provided data.

A high intrinsic growth rate would most likely be characteristics of
Answer:
r-selected species (e.g., American bullfrog)
Explanation:
The r-selected species (r-strategists) are those species in which their populations oscillate near the carrying capacity, i.e., the maximum population size sustained by a particular environment. These species are generally located in low-quality (less competitive) ecological niches and produce many offsprings that grow rapidly and have low chances of surviving to adulthood. Some examples of r-strategists include amphibians, fish, small mammals, etc. Conversely, K-selected species have more stable populations and produce a low amount of offspring (e.g., large mammals such as elephants).
Scientists interested in the relationship among vision, foraging for food, and fitness studied three isolated populations of a small species of primate whose diet includes small insects and fruit, both of which the animals primarily identify by sight. The three populations were once part of a larger population that was fragmented as a result of habitat destruction by humans. The study populations were selected on the basis of the significantly different vegetation among their current habitats. The scientists analyzed the frequency in each population of each of three alleles of a gene encoding an opsin protein. Opsin proteins are important for color vision, and each allele provides maximum sensitivity to a specific wavelength of visible light and thus to certain colors. Analysis of the alleles present in each population was performed in two different ways, and the data were combined to calculate the frequencies (Table 1).
Table 1. Frequency of opsin alleles in three populations of a small primate
Frequency (±2SEx¯)
Population 1 Population 2 Population 3
Allele 1 0.60 (.05) 0.80 (.06) 0.25 (.02)
Allele 2 0.15 (.02) 0.05 (.01) 0.45 (.03)
Allele 3 0.25 (.02) 0.15 (.02) 0.30 (.02)
(a) Describe one measure of evolutionary fitness.
(b) Using the template, construct an appropriately labeled graph to represent the data in Table 1. Based on the data, determine whether there is a significant difference in the frequency of EACH allele among the three primate populations.
Question 3
(c) Based on the data, identify the population that is likely to have the highest frequency of heterozygotes. Assuming random mating, calculate the frequency of animals in population 1 that carry both alleles 1 and 3.
Question 4
(d) A sudden event drastically changes the habitat of each population such that most of the normal vegetation and insects are replaced by other vegetation and insects. One of the scientists claims that population 2 will be the most severely affected. Predict the most likely effect of the event on population 2. Provide reasoning to justify your prediction.
a) Evolutionary fitness can be characterized as a person's commitment to the cutting edge's quality pool,which is chiefly founded on the aggregate or the genotype of the individual.This principally identifies with the conceptive achievement of an organic entity.
It is fundamentally determined by the offspring that can endure and pass on the characteristics/traits.
b) Graph is already uploaded in the below attached document.
c) The population 3 will have the most elevated frequency of heterozygotes,45% of the complete population.
d) Since population 2 is as of now having a low number of heterozygotes, the occasion would totally eliminate them from the population or decreases their number
Explanation:
Frequency of animals in population 1 having both alleles 1 and 3
frequency of allele 1 =0.60
frequency of allele 3= 0.25
Frequency of both allele 1 and 3 would be allele 1 + allele 3 frequency x 100
= 0.60+0.25 X 100= 85%

styrofoam a better insulator than plastic?"
Which experiment would be most effective in helping students obtain evidence to use in answering this question?
100 mL of 70 °C water placed in 200 mL plastic cup
O A. 100 mL of 10 °C water placed in 250 mL plastic cup
wait 20 minutes, remeasure temperatures
50 mL of 70 °C water placed in 250 mL styrofoam cup
OB. 100 mL of 70 °C water placed in 250 mL plastic cup
wait 20 minutes, remeasure temperatures
100 mL of 70 °C water placed in 200 mL plastic cup
OC. 100 mL of 70°C water placed in 200 mL styrofoam cup
wait 20 minutes, remeasure temperatures
100 mL of 70°C water placed in 250 mL styrofoam cup
OD. 100 mL of 20 °C water placed in 200 mL styrofoam cup

100 mL of 70 °C water placed in 200 mL plastic cup
O E. 100 mL of 70 °C water placed in 250 mL styrofoam cup
wait 20 minutes, remeasure temperatures
Answer:
C
Explanation:
The correct answer is C because it puts equivalent measurements in the equivalent cup size. Both cups in answer C are the same measurement: 200 mL. The water in both cups is also the same measurement: 100 mL of 70 degrees Celsius. This is important because equivalent measurements for everything mean the experiment will be fair, equal, and accurate. If the measurements were not equal to each other, your experiment would not be as accurate.

based on the living things in the pyramid, tell me what examples would fit into these categories: primary producers, primary consumers, secondary consumers, and tertiary consumers
Answer:
- Oak trees: primary producers
- Caterpillars: primary consumers
- Blue Jays: secondary consumers
- Hawks: tertiary consumers
Explanation:
A trophic pyramid, also known as ecological pyramid or energy pyramid, is a graphic representation that shows the relationships between different types of organisms (i.e., producers and consumers) at the trophic levels of an ecosystem. The primary producers are autotrophic organisms that obtain energy from sunlight and chemical compounds from nonliving sources (e.g., photosynthetic plants, algae, etc). The primary consumers are organisms that eat primary producers (e.g., herbivores), while secondary consumers are organisms that eat primary consumers (e.g., omnivores). Moreover, tertiary consumers are predators and/or omnivores that eat secondary consumers (e.g., hawks). Finally, decomposers (e.g., bacteria) are organisms that obtain nutrients and energy by breaking down dead organic material (i.e., dead organisms) at all trophic levels into nutrients.
