I think yes, because from what i knew. When the DNA replicate, it will be same as the original/mother DNA. so it will both have radioactive DNA.
Just think, if only one DNA have radioactive then it wont be dangerous, but it affect the replication DNA, then its different case and will be dangerous for the body. You must've heard that radioactive can be dangerous for the body.
Sorry if im wrong
Answer:
I would say one..
Explanation:
It says the new strands take u non-radioactive bases.. if he only used the radioactive to label one of them then I would say one..

Explain the difference between sex hormones and glandular stimulating hormones
Answer:
Sex hormones are those hormones that within the endocrine system of the human being, are considered more directly involved in human sexuality, particularly in the processes of copulation and reproduction.On the other hand, glandular stimulating hormones are those that act on hormonal production in another endocrine gland, that is, they are stimulants, since they stimulate the corresponding glands.
Explanation:
Sex hormones are chemical substances secreted by the sex endocrine glands (the testes and ovaries) and subsequently released into the bloodstream, to be transported to the organs on which they exert their action (increasing or decreasing their activity).The production of hormones is regulated in many cases by a negative feedback system, which causes an excess of a hormone to be followed by a decrease in its production. The glandular stimulating hormones are transported to the blood to stimulate the corresponding glands (thyroid, adrenal cortex, and gonads) and these will be the ones that secrete various types of hormones (thyroxine, corticosteroids and sex hormones, respectively), which in addition to acting in the body, they feed back into the pituitary and hypothalamus to inhibit their activity and balance the respective secretions of these two organs and the target gland. For example, follicle-stimulating hormone encourages sperm production in men and stimulates the ovaries to release eggs in women. Luteinizing hormone and follicle stimulator work together to allow normal function of the ovaries or testicles.

Why are normally unseen members of the food web, such as soil microorganisms, essential to the nitrogen cycle?
Answer: Why are normally unseen members of the food web, such as soil microorganisms, essential to the nitrogen cycle? ... Since not all organisms can utilize the nitrogen gas directly, these microorganisms convert nitrogen in different nitrogen compounds, such as ammonia, nitrites, and nitrates. In this article we explore how nitrogen is cycled and the important role of microbes in this cycle. ... Nitrogen is required by all living organisms for the synthesis of organic molecules such as amino acids, nucleic acids and proteins. The Earth's atmosphere contains almost 80% nitrogen gas
Bacteria play a central role:
Nitrogen-fixing bacteria, which convert atmospheric nitrogen to nitrates.
Bacteria of decay, which convert decaying nitrogen waste to ammonia.
Nitrifying bacteria, which convert ammonia to nitrates/nitrites.
Denitrifying bacteria, which convert nitrates to nitrogen gas.

What can you conclude about starch, glucose and their movement across the Visking tubing? , What implications does this have for starch and glucose in the small intenstine?
Answer:
Starch molecules is too large therefore cannot pass through pores of visking tubing, glucose molecules is small enough to pass through pores of visking tubing. Visking tubing is like small intestine in this experiment, where starch is too large to be absorbed through small intestine into bloodstream, glucose is small enough to diffuse through small intestine and to be reabsorbed into bloodstream.
Compare the effect of acetylcholine on cardiac muscle with its effect on skeletal muscle. Can you explain the mechanistic basis for the difference
Answer:
The action of the neurotransmitter acetylcholine, released by the vagus nerve in the heart, slows the heart rate and weakens the force of contraction. The skeletal muscle has the ability to perceive a stimulus and respond to it. As regards skeletal muscles, the stimulus is chemical in nature: acetylcholine released by the motor nerve ending. The response of the muscle fiber is the production and propagation along its membrane of an electrical current (action potential) that causes muscle contraction.
Explanation:
Acetylcholine is one of the most abundant neurotransmitters in the central and peripheral nervous system. Acetylcholine receptors are nicotinic (ionotropic) and muscarinic (metabotropic GPCR). In skeletal muscle of adults, acetylcholine binds to the alpha subunit of the nicotinic channel, which are two of the five subunits that make up the pore of this channel. Acetylcholine released by the nerve ending binds to the receptor in the sarcolemma and triggers an electrical current - the action potential. This spreads along the sarcolemma and causes a signal to pass from the T tubule to the sarcoplasmic reticulum in the triad, which then releases calcium ions (Ca ++). Once the calcium ions are released, by diffusing between the actin and myosin protein filaments, they cause the myofibrils to contract. On the other hand, in cardiac and smooth muscle cells, acetylcholine binds to 7M proteins, which do not function as channels, but are typical members of the GPCR class A superfamily. One of the physiological mechanisms of acetylcholine is the regulation of the heart rate, through the mobilization limited to the inner face of the plasma membrane of the dimer bg of protein G. This dimer transduces the specific binding of the ligand with its receptor in the plane of the membrane, thanks to its proximity with the ion channel or with enzymes bound to the plasma membrane. This can be done because its g subunit remains attached to the inner face of the membrane.

In the oceans on either side of the Isthmus of Panama are 30 species of snapping shrimp, 15 species on the Pacific side and 15 different species ch the Atlantic sid. See different water depths. Morphological and genetic data show that Atlantic and Pacific species that live at similar depths are sister species. Geological evidence indicates that the Isthmus of Panama started rising about 10 million years ago and the oceans were completely separated by the stimus about 3 million years ago. If the geological evidence has been misinterpreted and the isthmus had formed very rapidly in less than 1,000 years), which of the following predictions is most likely?
A. greater percentage of difference in DNA sequences between sister species that inhabit deep water than between sister species that inhabt stalow water
B. greater percentage of difference in DNA sequences between sister species that inhabit shallow water than between sister species that inhabit deep water
C. similar percentages of difference in DNA sequences between all pairs of sister species
D. greater percentage of difference in DNA sequences between Atlantic species than between Pacific species
Answer:
The answer is "Choice A".
Explanation:
The Panama isthmus is indeed a patch of land which separates its sea from its Atlantic ocean to The pacific in two halves. The Panama Isthmus allows spreading the seafood applicable state, although due to geographical barrier, the very same turtle species were isolated. Its deep squirrels of liquid are diverged quite early as being against shallow water shrimps which are characterized by the rising of the Jamaica isthmus, first off the island can be crossed until it was closed through shallow water prawns and shallow-water animals. If Panama's black sea was established less than 1000 years, it has a greater effect on deepwater shrimp and very low water lobsters. Consequently, in water depth prawns, a disparity in hereditary degree (DNA) is higher than in shallow species. The deep waters have been affected earlier so the variation in DNA sequences throughout all sister species will not be the same.
Using compaction and cementation explain why sedimentary rocks are not just a loose pile of sand and rocks.
Compaction and Cementation They are compacted, reducing the available pore space and expelling much of the pore-water. Dissolved minerals in the ground water precipitate (crystallize) from water in the pore spaces forming mineral crusts on the sedimentary grains, gradually cementing the sediments, thus forming a rock.
Through compaction and cementation, minerals form a crusts on the sedimentary rocks which are no longer just a loose pile of sand and rocks.
What are sedimentary rocks?Sedimentary rocks are formed from the pre-existing rocks or pieces of or fossils of living organisms. They form from the deposits which accumulate on the surface of Earth. Sedimentary rocks often have distinctive layering or bedding over Earth.
Dissolved minerals present in the ground water precipitates from the water surface present in the pore spaces forming mineral crusts on the sedimentary grains, which gradually undergo cementing the sediments, which thus lead to formation of a rock.

Why bacteria generally dies in the presence of oxygen ?
Bacteria that require oxygen to grow are called "obligate aerobic bacteria". Without oxygen they generally die since these bacteria require oxygen to grow.
Their methods of energy production and respiration depend on the transfer of electrons to oxygen.
A membrane attack complex is a protein grouping that Multiple Choice stimulates basophils to attack a multicellular parasite in the body. triggers phagocytosis of a target cell by a nearby macrophage or neutrophil. links a pathogen to a red blood cell so that it is carried to the liver or spleen. forms a channel in the target cell membrane that causes cytolysis.
Answer:
The correct answer is ''forms a channel in the target cell membrane that causes cytolysis.''
Explanation:
The membrane attack complex (MAC) has the essential effect of producing a notable osmotic imbalance in the microorganism that leads to its cytolysis (in Gram-negative bacteria it inserts into the outer membrane, favoring the entry of lysozyme, and in Gram-positive ones insert into the cytoplasmic membrane, destroying the electrochemical gradients). The lytic pathway corresponds to the final reactions of the complement system. It begins when the C5 convertase enzymes formed either in the classical pathway, MBL or the alternative, fix the factor C5 and fragment it into C5a (anaphylatoxin) that passes into the fluid medium and C5b, which binds non-covalently to C3b. The C5b fraction captures C6 and C7 from the fluid phase, forming a stable C5b67 complex with chemotaxic activity and membrane-binding capacity, which when joining the C8 fraction is cytolytic, and acquires the ability to interact with C9 molecules, forming the complex C5b6789. The C9 molecules then undergo conformational changes, enhance and accelerate the penetration of this membrane attack complex (MAC), giving rise to the formation of channels that allow the free exchange of sodium and water with the outside of the cell, causing the consequent osmotic lysis (cytolysis)of the attacked cell, since C9 is structurally homologous to perforin, a protein released by cytotoxic T lymphocytes and NK cells, and which is also responsible for the formation of pores in the membrane of the target cells.

Explanation:
Cape Town, South Africa has a significant water shortage. The amount of water available is not sufficient to support the current human population of the city.
Which three factors most likely contributed to the growing water shortage?
- Strict water management policies.
- Naturally-occurring drought conditions.
- Underdeveloped alternative and supplemental water sources.
- Migrations of residents out of the city and into surrounding areas.
- Higher demand for water than natural reservoirs accumulate each year.
Explanation:
The city's water supply shortage seems to be the result of a combination of physical, social, and political factors. Well below-average rainfall patterns, the increasing unpredictability of weather conditions due to anthropogenic climate change impacts, population growth, and government mismanagement have produced one of the worst urban water crises in recent memory.
here is the reason your explanation from the water shortage now just figure out what the factors are in your answers I would say it's naturally occurring drought conditions because it says on here well below average rainfall patterns and climate change
Water shortage can occur as a result of mismanagement practices by humans or as a result of natural occurrences such as droughts.
What is water shortage?Water shortage refers to a situation in which there is not enough water to meet the daily water needs of the human, animal and plant population in a particular area.

Explanation:
Deadly gas. Carbon monoxide is a colorless, odorless gas that binds to hemoglobin at an oxygen-binding site. Indeed, it binds 200 times as tightly as oxygen, accounting for its toxic nature. Even if only one of the four oxygen-binding sites on hemoglobin is occupied by carbon monoxide and the remaining three are bound to oxygen, oxygen is not released. Explain.
Answer:
The binding of carbon monoxide (CO) with hemoglobin leads to an R state even in conditions that should produce the release of oxygen. In consequence, CO-hemoglobin binding shifts the oxygen dissociation curve to the left.
Explanation:
Hemoglobin is a globular protein containing four heme groups that can bind to one oxygen each. This protein (hemoglobin) has two conformational states: the T-state, also known as deoxyhemoglobin (a tense state, where lacks O species), and the R-state, also known as oxyhemoglobin (a relaxed, fully oxygenated state). When carbon monoxide binds to hemoglobin, the protein can not release oxygen, shifting the oxygen dissociation curve -which expresses the percentage of oxygen saturation against the partial pressure of oxygen- to the left. Therefore, under CO-hemoglobin binding, the oxygen level in the tissues is reduced.
