During the replication of DNA:
A. both strands of the DNA molecule act as templates
B. only one strand of DNA acts as a template
C. the cell also undergoes mitosis
D. the reaction is catalyzed by RNA polymerase
Answer:
A
Explanation:
Both strands of the DNA molecule act as templates
Both strands will be divided and then used to make two new DNA strands, each with half of the original
During DNA replication, the two strands of the DNA molecule act as templates. Because the fret has been divided into two pieces, each new DNA strand contains half of the original strand.
What is DNA?DNA, or deoxyribonucleic acid, is the molecule that carries the genetic material required for an organism's growth and operation. DNA has a double helix structure, which is made up of two connected strands that loop around one another to form a twisted ladder.Depending on your parents, half of your genome is inherited from your mother and half from your father. The information molecule is DNA. It stores instructions for the production of larger molecules known as proteins. These instructions are stored within each of your cells and are distributed across 46 long structures known as chromosomes. These chromosomes are composed of thousands of shorter DNA segments known as genes.To learn more about DNA refer to:

what process involving cell division results in daughter cells that are not identical to the parent cell?
Answer:
meiosis
Explanation:
Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.
what do the three major checkpoints for cell division have in common?
Answer:
There are three major checkpoints in the cell cycle: one near the end of G1, a second at the G2/M transition, and the third during metaphase. Positive regulator molecules allow the cell cycle to advance to the next stage. ... Each successive cell division will give rise to daughter cells with even more accumulated damage.

A nuclear chain reaction happens when a single nuclear event averages out one or more further nuclear reactions, opening the door for a potentially endless chain of similar processes. Therefore, option (A) is correct.
What is a nuclear chain reaction ?A nuclear chain reaction happens when the output of one nuclear reaction triggers the occurrence of further nuclear reactions. These cascade reactions are nearly invariably a succession of neutron-excessive fission events. The moniker "chain reaction" comes from the fact that these extra neutrons have the potential to trigger more fission events. The functioning of nuclear power plants depends on nuclear chain reactions.
About a million times more energy is released during nuclear reactions than during chemical ones. Every fission event must result in precisely one additional fission event in order for a nuclear chain reaction to continue.
Therefore, option (A) correctly describes the nuclear reaction.

How does the evolution of resistance in bacteria affect humans
Answer:
Bacteria, not humans or animals, become antibiotic-resistant. These bacteria may infect humans and animals, and the infections they cause are harder to treat than those caused by non-resistant bacteria. Antibiotic resistance leads to higher medical costs, prolonged hospital stays, and increased mortality.

Why does a plant produce more sugar after summer?
Answer:
Sunlight = Energy
Explanation:
Plants have chlorophyll that uses sunlight from the sun to create energy.
The energy is then used to change carbon dioxide from the air into sugars like glucose. The plant transports sugars into the tissues like roots, flowers and fruits so it can grow.
Answer:
Plants have chlorophyll that uses sunlight to gather energy. The energy is then used to change carbon dioxide from the air into sugars like glucose and fructose. ... They transport sugars throughout the plant and supply it to tissues like roots, flowers and fruits that depend on this sugar to grow.

The luminous reactions begin when light reaches photosystem II. The water molecules provide electrons to the photosystem, releasing oxygen and protons. The letter A represents photosystem II that splits water.
-----------
1. Luminous energy is trapped by chlorophyll in Photosystem II.
2. When the pigment molecules absorb light, electrons provided by water molecules get in a higher energy level.
3. The excited electrons go through the electron transport chain from Photosystem II to a less energetic level in photosystem I.
4. When the excited electrons leave photosystem II, they are replaced by new electrons extracted from the water molecules.
5. Luminous energy absorbed move the electrons from the photosystem I to another electron acceptor, from where they get transported again and used to produce NADPH molecules.
6. When electrons leave Photosystem I, they are replaced by new electrons coming from photosystem II.
7. When the water molecule breaks down, hydrogen ions remain in the thylakoid lumen, from where they are pumped to the stroma by the ATP synthase.
8. The released energy is used to produce ATP molecules.
9. Hydrogen ions go back from the stroma to the thylakoid compartment.

un estudio sanguineo al que fue sometido carlos arrojo los siguientes resultados (mg/ml): glucosa 90, trigliceridos 120, hemoglobina,14 y acido urico 6.¿ cual de ellos corresponde a un lipido?
un estudio sanguineo al que fue sometido carlos arrojo los siguientes resultados (mg/ml): El que corresponde a lípidos son los triglicéridos.
Los resultados del estudio de sangre al que fue sometido Carlos son:
glucosa = 90 mg / ml triglicéridos = 120 mg / ml hemoglobina = 14 mg / ml ácido úrico = 6 mg / mlA partir del resultado dado, la opción que corresponde a los lípidos son los triglicéridos.
Los triglicéridos son lípidos (grasas cerosas) que proporcionan energía al cuerpo. Los triglicéridos son producidos por nuestro cuerpo y se obtienen de las comidas que ingerimos. Un triglicérido es un tipo de lípido compuesto por glicerol y tres moléculas de ácidos grasos.
La glucosa tiene la fórmula molecular C6H12O6 y es un azúcar simple. La glucosa es el monosacárido más ubicuo que es un tipo de carbohidrato. La glucosa es producida principalmente por plantas y algas cuando realizan actividad fotosintética a partir del agua y el dióxido de carbono con la ayuda de la luz solar, donde se utiliza para crear celulosa en las paredes celulares.
La hemoglobina es una proteína que se encuentra en los glóbulos rojos (RBC) que transporta oxígeno a los órganos y tejidos y transporta el dióxido de carbono (CO2) de los órganos y tejidos de regreso a los pulmones.
El ácido úrico es un producto de desecho que puede detectarse en la sangre. Se forma cada vez que el cuerpo descompone las purinas. La mayor parte del ácido úrico se disuelve en la sangre, viaja a través de los riñones y se excreta en la orina.
Por tanto, de la explicación anterior, podemos concluir que el resultado que corresponde al lípido son los triglicéridos.

The descriptions below explain two ways that water is used by plants on a sunny day.
I. In a process called transpiration, some liquid water in leaves changes to water vapor. The water vapor is released into the air through tiny pores in the leaves. This allows more liquid water from the soil to be pulled up the roots and stem to replace water lost from the leaves.
II. Plants use some of this water in leaves in a process called photosynthesis. During photosynthesis, water and carbon dioxide break apart and recombine to form two new substances, oxygen, and glucose.
Based on the above description of transpiration and photosynthesis, which type of change happens to water during each process?
A. In transpiration, because some of its properties change, water undergoes a physical change but keeps its identity. In photosynthesis, because its identity changes, water undergoes a chemical change.
B. In transpiration, because some of its properties change, water undergoes a chemical change but keeps its identity. In photosynthesis, because its identity changes, water undergoes a physical change.
C. In transpiration, because its physical properties change, water undergoes a physical change and loses its identity. In photosynthesis, because it keeps its identity, water undergoes a chemical change.
D. In transpiration, because its chemical properties change, water undergoes a chemical change and loses its identity. In photosynthesis, because it keeps its identity, water undergoes a physical change.

When liquid turns into vapor
Explanation:
hope this helps <33
have a nice day
mark as brainliest plz? :)
A liquid turning into a gas is evaporation. It is how water gets from the surface of the Earth to the atmosphere.
Temperature, surface area, wind speed, and humidity affect a liquid's evaporation rate.
Latent heat is a form of energy held in the evaporated water when it evaporates and cools.
Most of the air's moisture evaporates from rivers, lakes, seas, and oceans. Water at the surface of the Earth evaporates into water vapor, which rises into the sky and forms clouds, which eventually release water back onto Earth as precipitation.
