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.
What is the greenhouse effect? How can humans reduce the level of greenhouse gases?
Answer:
The greenhouse effect is the production of harmful gases that harm the atmosphere.
Humans can reduce the level of greenhouse gases by opting for alternate technologies or reducing their carbon emissions.
Explanation:
The greenhouse effect is the process of heating the earth's atmosphere by trapping the Sun's energy, thereby making the atmosphere hot. This natural process of trapping the heat is caused by numerous gases like methane, carbon dioxide, water vapor, and other gases. It's from this process that the atmosphere produces bad gases that damage the earth.
The reduction of the effect can be reduced by humans if they reduce their consumption of resources or energy. Moreover, shifting to alternate technologies that use lesser or no gasoline will also help in the reduction of greenhouse gases.

what is your personal responsibility towards the environment? give 100 words
Answer:
My personal responsibility to the environment, as cataloged in the Brundtland report, is sustainability, I mean, ensuring that future generations will be able to enjoy the same quality and quantity of resources that I can have at this time, to I plan to make efficient use of services such as drinking water and electricity, make a correct separation at the source of solid waste so that the reusable material can be used and not cause unnecessary pressure on the earth's mantle, on the other hand, make a more continuous use of reusable or biodegradable material, in order not to increase pollution by waste that usually has as its final destination, in many cases, water sources such as the oceans, as well as reduce my consumption and that of my family of meat products, and products with chlorofluorocarbon gases, thus reducing the amount of gases that are deployed to the atmosphere and could destroy it.
Explanation:
The environmental commitment is something extremely important to allow there to be a true environmental sustainability beyond an advertising attractor, for this it is required that each person identify activities in which they can reduce the generation of pollutants, either through solid waste, dumping or gases. that affect the ozone layer such as methane or chlorofluorocarbon gases, these activities can regularly be carried out from our own homes and, although they may involve additional work, they will allow future generations to enjoy an environment with a quality similar to or better than the one we have currently.
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).

What are two ways in which ultrasound technology produces images?
A. By the absorption of sound waves in the body
B. By detecting the frequencies of emitted sound waves
C. By using sound in frequencies that reflect off body tissues
D. By measuring the time it takes for reflected sound waves to be
detected
C and D
Hope this helps have a great day!!
The ultrasound images are produced by using the sound frequencies that reflect off body tissues and by measuring the time it takes for reflected sound waves to be detected. So the correct options are C and D.
What is ultrasound imaging?High-frequency sound waves are used in ultrasound imaging, also known as sonography, to look within the body.
Real-time ultrasound imaging allows for the display of blood flowing via blood vessels as well as the activity of the body's interior organs.
Contrary to X-ray imaging, ultrasonic imaging does not expose patients to ionizing radiation. A transducer (probe) is positioned either on the skin or within a bodily orifice during an ultrasonic examination.
To allow the ultrasonic waves from the transducer to pass through the gel and into the body, a small coating of gel is placed on the skin.
The ultrasound picture is created as a result of the waves' reflection off the body's structures. The information required to create a picture is provided by the intensity (amplitude) of the acoustic signals and the duration of the wave's passage through the body. Therefore the correct options are C and D.

Which of the following could be a hypothesis for the function of the thick,
waxy coating on a pine needle?
A. If the thick, waxy coating is destroyed, the pine needle will turn
brown.
B. The thick, waxy coating prevents water loss.
C. What happens to the needle if the thick, waxy coating is
destroyed?
D. The tree would feel cold without the thick, waxy coating.
Answer:
B. The thick, waxy coating prevents water loss.
Explanation:
This is because the thick waxy coating needle refer to structure posses by plants or mostly xerophites plants to adapt to their environment. Plants that grow in area where there is no abundance of water for use normally posses these structures which will reduce evapotranspiration and conserve water. These plants normally have extensive roots to draw water.

In the beginning man was born from creatures of a different kind; because other creatures are soon self-supporting, but man alone needs prolonged nursing.
a. True
b. False
Answer: True
Explanation:
The statement that "In the beginning, man was born from creatures of a different kind; because other creatures are soon self-supporting, but man alone needs prolonged nursing" is true.
The creatures that were different from man became self supporting soon. If the present form had been the original form of man, he won't have survived.
(20 POINTS!!) Respiration is a process where many chemical bonds inside the body break and release energy. This energy is used to perform various activities such as moving muscles. Explain the energy transformation in this process.
A. Chemical energy from broken bonds is transformed into mechanical energy for muscles.
B. Mechanical energy from broken bonds is transformed into chemical energy for muscles.
C. Mechanical energy from broken bonds is transformed into electrical energy for muscles.
D. Heat energy from broken bonds is transformed into electrical energy for muscles.
Answer:Cellular respiration is the process of transforming chemical energy into forms usable by the cell or organism. Organisms ingest organic molecules like the carbohydrate glucose to obtain the energy needed for cellular functions. The energy in glucose can be extracted in a series of chemical reactions known as cellular respiration. Most energy is produced during cellular respiration in the mitochondria, a process that involves breakdown of simple sugars to produce energy in the form of ATP, which is the usable form by the cell.
