in the uvr excision repair system in e. coli, which enzyme routinely synthesizes dna to replace the excised strand?
DNA polymerase I an enzyme routinely synthesizes DNA to replace the excised strand.
An enzyme called DNA polymerase to takes a role in the replication of bacterial DNA. It was the first known DNA polymerase, and Arthur Kornberg discovered it in 1956. It was first identified in E. coli and is found in all prokaryotes.
During lagging-strand synthesis, DNA polymerase I (pol I) processes RNA primers and fills up tiny gaps during DNA repair events. By extending the 3′ ends of an existing nucleotide chain and adding new nucleotides that are identical to the template strand one at a time using the formation of phosphodiester bonds, DNA polymerase adds a new strand of DNA.

The table shows the energy that is stored in three types of organic molecules.
Energy Storage in Humans
Free glucose in blood has 4 kilocalories per gram, 40 kilocalories of energy storage, and a few minutes of life support time. Glycogen has 4 kilocalories per gram, 600 to 1600 kilocalories of energy storage, and 1 day of life support time. Lipids have 9 kilocalories per gram, 100,000 kilocalories of energy storage, and 30 to 40 days of life support time.
What is the best conclusion based on this data?
Blood is a primary location for energy storage.
Fat molecules contain more energy-containing bonds than simple sugars.
A gram of glycogen has twice as much energy as a gram of fat.
The human body stores approximately 1,000 kcal of glucose.
Based on the data shown, the best conclusion would be that fat molecules contain more energy-containing bonds than simple sugars. Option 2.
Drawing conclusions based on dataFrom the available data shown in the illustration, the following can be deduced:
1 gram of free glucose = 4 kilocalories, 40 kilocalories of energy storage, few minutes of life support.1 gram of glycogen = 4 kilocalories, 600 to 1600 kilocalories of energy storage, 1 day life support.1 gram of lipid = 9 kilocalories, 100,000 kilocalories of energy storage, 30 to 40 days of life support.Based on the information extracted, one can see that glucose offers the lowest amount of energy, storage energy, and life support time per gram.
On the other hand, lipid appears to offer the highest energy, storage energy, as well as life support time. Glucogen has values that lie in-between glucose and lipid.
In other words, fats being a type of lipid appears to contain more energy-containing bonds than simple sugar, glucose.

killed vaccines work by stimulating phagocytic activity. cytotoxic t cells. lymphocyte proliferation. an antibody response. the cell-mediated immune response.
Killed vaccines work by stimulating an antibody response. An antibody response is the culmination of a series of interactions between macrophages, T lymphocytes, and B lymphocytes
Inactivated vaccines, commonly referred to as killed vaccines, include virus particles, bacteria, or other pathogens whose genetic material has been damaged by heat, chemicals, or radiation so they cannot multiply in cells but can still elicit an immune response.
Although their genetic material has been destroyed, inactivated viruses typically still include a large number of proteins that the immune system may recognize and respond to. However, because inactivated vaccines can't infect cells, they can only induce antibody-mediated reactions, which may be weaker and shorter-lived. Inactivated vaccinations are frequently administered with adjuvants (agents that stimulate the immune system) and booster doses could be necessary to address this issue.

The correct response is complement. It do not have a function or role in both the innate and adaptive immune system.
Adaptive immune responses have the purpose of eliminating invasive infections and any hazardous chemicals they may create. It is essential that these responses are only created in response to molecules that are foreign to the host and not the molecules of the host itself because they are damaging. Innate immunity, also known as nonspecific immunity, is the defense mechanism you were born with. You are shielded from all antigens by it.

describe the events that occur at the neuromusclar junction and how the action potential is generated
An action potential travels down the axon upon depolarization, causing voltage-gated calcium channels to open, resulting in an influx of calcium ions into the nerve terminal.
A neuromuscular junction (NMJ), also known as a myoneural junction, connects motor neurons to muscle fibers. This is the location where the neuron sends a signal from the brain to the muscle fiber, causing it to contract.
The nerve fiber can send a signal to the muscle fiber at the neuromuscular junction by releasing ACh (and other substances), causing muscle contraction.
When the nervous system sends signals to the muscles, they either contract or relax. The signal exchange takes place at the neuromuscular junction.

What provides the heat that drives the formation of igneous and metamorphic rocks?
Answer:
Something known as magma chambers.
Explanation:
A magma chamber is a big blob of melted, liquid rock within the Continental Crust.
The rock under our feet (Continental Crust) is basically solid. At subduction zones, in particular, friction (or other) heat can melt the rock at the base of the Continental Crust, and then blobs of molten rock melt their way upwards into the Continental Crust. That’s a magma chamber.
Sometimes the magma chamber has vents leading up to the open air and the magma erupts as volcanoes. In that case, the magma chamber can empty out and the ground above collapses into it, making a hole called a caldera. But more often, the magma in the magma chamber cools down to form solid rock. Such slow-cooled rock will form crystals as it cools. One form of such crystalline rock is granite; cooled down former magma chambers now solid granite are called plutons or batholiths. Typically they will be several kilometres across, and later erosion may well expose them at the surface.

The factors that limit the size and growth of a population in Serengeti is the food supply and predation.
Population in Serengeti have suffered from competition in resource availability. Other density-dependent variables may have placed restrictions on these populations. These could be top-down elements excluding predation or bottom-up factors like food, water, or habitat. Similar to wildebeest, non-migratory zebra populations may be constrained by predators, and migratory populations may be constrained by food.
Wildebeest populations in the Serengeti increased from 770,000 in one year to 4 million in just four years, barely more than one generation. Any element (variable) in the environment that has the potential to restrict a process, such as the expansion, abundance, or distribution of a population of species in an ecosystem, is referred to as a limiting factor.
