During DNA replication, the DNA polymerase enzyme produces a complemetary strand from each of the original strands.
What is DNA replication?It is the process by which DNA produces a copy of itself at the time of cell division. In the process of replication, the initial step is the unzipping of the double helix structure of the DNA. This is done with the help of enzyme helicase. The unzipping creates a Y shape composition called replication fork.
Towards the replication fork, one of the strands is oriented in the 3' to 5' direction, known as the leading strand. The other strand in the 5' to 3' direction is the lagging strand, which is away from the replication fork.
The primer combines with the leading strand, and marks the intiation point of the synthesis of DNA. After this, DNA polymerase combines with the leading strand and add complementary nucleotide bases in the 5' to 3' direction.
In the lagging strand, numerous primers come and bind, later the chunks of DNA called Okazaki fragments are supplemented to the lagging strand in the 5' to 3' direction, by the enzyme DNA polymerase. This kind of replication is termed discontinuous as the Okazaki fragments are joined up later.
Thus, the correct statement is the second one, that is, the DNA polymerase enzyme produces a complemetary strand from each of the original strands.

Answers
Answer:
Decomposers recycle essential nutrients back into an ecosystem.
Explanation:The decomposers are the small microorganisms which can be found in the soil habitat. These organisms obtain energy by break down of organic matter generated after the death of plants, animals and their residual matter. Through the process of decomposition the decomposers release nutrients such as nitrogen and carbon back to the environment. These nutrients are absorbed by the plants through soil. This way the nutrients are recycled in an ecosystem by decomposers.

this is you're answer please give me thanks
Answer:
In cells, oxygen is needed for aerobic respiration, which allows for the extraction of energy from ingested foods. Thus supplemental oxygen at home and in hospitals is vital for those with breathing disorders such as emphysema.
Compressed oxygen tanks are used by mountaineers at high elevations to counteract the decreased O2 pressure at these altitudes.
Supplemental oxygen is needed for surgical patients intentionally rendered paralyzed for medical procedures, in which "heart-lung machines" keep their vital functions going.
Oxygen can be used as a sterilizing agent to kill certain anaerobic bacteria that are killed by sufficient exposure to the gas.
Industrial Uses of Oxygen:
Oxygen is needed for the reaction that converts carbon to carbon dioxide gas in steel working, which takes place under high temperatures in a blast furnace. The carbon dioxide produced allows for the reduction of iron oxides into more pure iron compounds.
Oxygen is used in other applications involving metal and requiring high temperatures, such as welding torches.
Aerospace Uses of Oxygen:
In liquid form, oxygen is used widely as an oxidizing agent for use in missiles and rockets, where it reacts with liquid hydrogen to produce the terrific thrust needed for take-off. Astronaut spacesuits include a nearly pure form of oxygen.
Oxygen is used to degrade hydrocarbon compounds, which are broken apart by heating them. This is used to create combustion that usually liberates water and carbon dioxide, but can also produce the hydrocarbons acetylene, propylene and ethylene.
Oxygen is used in sewage-treatment and water-purification plants. It is forced through water to increase the production of bacteria that metabolize waste products in the water.
Oxygen gas (O2) is needed to produce energy in things not linked to an electrical supply of their own, such as generators and vehicles (e.g., ships, airplanes and cars).

Meerkats live together in groups to help raise and protect their offspring. Meerkat pups are most vulnerable when they are away from their burrow foraging for food. Adult meerkats exhibit sentinel behavior, standing upright and making alarm calls to warn other members in the group that predators are nearby. In a study of meerkat behaviors, scientists observed meerkat foraging groups and recorded the presence or absence of pups along with the frequency of adult sentinel behavior. The scientists determined that sentinel behavior increased when pups were present in the foraging group. Which of the following correctly identifies the dependent and independent variables in the described study? A. The frequency of sentinel behavior is the independent variable, and the presence of pups is the dependent variable. B. The presence of pups is the independent variable, and the frequency of sentinel behavior is the dependent variable. C. The number of predators is the independent variable, and the presence of pups is the dependent variable. D. The distance from the burrow is the independent variable, and the number of predators is the dependent variable.
Answers
Answer:
The correct answer is - option B. The presence of pups is the independent variable, and the frequency of sentinel behavior is the dependent variable.
Explanation:
The independent variable in a study or experiment is a variable that is subject to change or manipulated to see the effect on the result of the study by influencing the dependent variable. In this study, the independent variable that is manipulated is the presence of the pups to see what is led to the behavior of meerkats.
The dependent variable is a variable that is influenced in a study by the independent variable and led to the result of the study as the frequency of sentinel behavior is influenced by the presence of the pups so the dependent variable here is the frequency of sentinel behavior.

Why is the hydrolysis of water required for photosynthesis?
Answers
Hydrolysis is a chemical process in which a water molecule is inserted.
In light-based reaction, which occurs in the thylakoid layer, chlorophyll absorbs energy from the sun and converts it into chemical energy through water. Light-dependent reactions release oxygen to water hydrolysis as a by-product.
Hope it helps!
Water is one of the most important components of photosynthesis. The hydrolysis of water is required to provide the Electrons and protons( Hydrogen ions) in photosynthesis.
Light Reaction photosynthesis:
It is the phase in which plant cells produce NADPH and ATP via the energy of the electron transport chain.
In this phase,
The water hydrolyzes to produce, electrons and Hydrogen Ion. Electrons move in from protein to protein and release their energy.This energy is used to pump the more hydrogen ion into the thalakoid lumen. The final electron is used to reduce the NADP molecule.Therefore, the hydrolysis of water is required to provide the Electrons and protons( Hydrogen ions) in photosynthesis.
