Answer:

Alfred Hershey and Martha Chase

Explanation:

In 1952 Alfred Hershey and Martha Chase were working with bacteriophages or phages, which are viruses that infect bacteria. They knew that a phage had an outer shell of protein and an inner core of DNA. In addition, from the electron microscope observations, they also knew that during infection the virus attacks the bacterium by its tails and introduces its genetic material into the bacterium to multiply using its metabolic machinery. They radioactively labeled two sets of phages: one with 32P (which marks only DNA) and another with 35S (which marks only proteins). In two parallel experiments, they infected bacteria with viruses marked on their DNA and with viruses marked on their proteins. The cultures were shaken with a mixer to separate the virus particles from the bacterial coatings. They then performed a centrifugation to separate the phages from the bacteria, so that the larger and heavier bacteria remain in the pellet, while the phages remain in the supernatant. They found that the radioactivity of 35S appeared in the supernatant while that of 32P appeared in the sediment, from which new radioactively labeled virus particles appeared, demonstrating that DNA was the genetic material.

Answer: The carbon cycle is nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms

Explanation:

Answer:

44 N

Explanation:

Force applied can be calculated using the formula as follows;

F = m.a

Where;

F = force (Newton)

m = mass (kg)

a = acceleration (m/s²)

According to the information provided in this question, mass of shot put = 5.5kg, acceleration = 8m/s². Hence;

F = m × a

F = 5.5 × 8

F = 44 Newtons

The force needed by the shot putter is 44N.

Answer:

when body temperature rises, such as when exercising on a hot day, the dermal blood vessels will dilate, in the sweat glands begin to secrete more sweat. the invaporation of the sweat from the surface of the skin cools the body by dissipating heat.

Explanation:

Hope this helped Mark BRAINLEST!!!

Answer:

When it is hot, we normally sweat. Sweating removes the heat energy from our skin. Our blood vessels open up which lets more blood flow. This allows a way for the heat to be lost. It lets your body cool down or try and cool down.

Answer:The source of a river or stream may be a lake, a marsh, a spring, glacier, or a collection of headwaters. The furthest stream is called the headstream. Headwaters are small streams that create the river or stream and may be cool waters, because of shade and barely melted ice or rain.

The Answer Is A.

Explanation:

If They Can Be Used For Cleaning Up Mining Waste And For Sewage Treatment, That Makes Them A Good Thing. So It Wouldn't Be A Concern. Hope This Helps.

Genetically engineered bacteria cells can be used to clean up mining waste and for sewage treatment, which is not an ethical concern raised by genetic engineering. So, the correct option is A.

Genetic engineering may be defined as a process that involves the manipulation of the genetic material of organisms with help of lab-based technologies.

Bacterial species produced by genetic engineering used in cleaning up mining waste and sewage treatment benefit the atmosphere by reducing the level of waste and toxic compounds from suuroundings. So, it is not a matter of ethical concern.

Therefore, the correct option for this question is A.

Answer: Imma say In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water. The light-dependent reactions release oxygen as a byproduct as water is broken apart.The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. ... The photosystems and electron transport chain components are embedded in the thylakoid membrane.

Answer:

Enzyme activity depends on many factors such as Substrate concentration, enzyme cofactor, enzyme inhibitors, pH, and temperature. pH and temperature are two important factors that directly affect the activity of an enzyme as follows:

1. pH

Each enzyme has the specific optimal pH that allows it to perform its function to its fullest. The enzymes are the protein made up of the interaction of the hydrogen bond in the side chain of the protein. if there is any change from optimum pH, the enzyme activity decreases until it stops working.

2. Temperature:

Each enzyme has its own optimal temperature. Any modification or change in temperature results in the activity of an enzyme, and it also leads to the denaturation of an enzyme as it is made up of protein.

Answer: Because Meiosis only occurs in reproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Meiosis is important to, but not the same as, sexual reproduction. Meiosis is necessary for sexual reproduction to occ Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.ur, as it results in the formation of gametes (sperm and eggs). Hope this helps have a awesome day/night❤️✨

The virus recognizes and binds to a host cell via a receptor molecule on the cell surface.

The virus or its genetic material enters the cell

The viral genome is copied and its genes are expressed to make viral proteins.

New viral particles are assembled from the genome copies and viral proteins.

Completed viral particles exit the cell and can infect other cells.

Fitness or aptitude

Explanation:

Aptitude (or fitness) is the genotype/phenotype that results in the survival, fertility, and capability of having a mate. It is a way of measuring the individual ability to leave fertile offspring.

Aptitude puts together everything that matters in natural selection. Includes the survival capability, finding a mate partner possibility, producing fertile descendants, and leaving the genes to the next generation. The aptitude of a genotype must be significant for natural selection to act in its favor.
