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:

according to plato, where do souls have to drink before starting their new lives on earth?
According to Plato, the souls of people tend to reincarnation, that is, the souls of each person have had previous lives in which they have developed and have had different experiences.
Thus, as a way to generate an impartiality of the soul, which allows it to start a new life without influences on previous lives, they should drink water from the River of Forgetfulness.
This made the souls unable to remember anything from their previous lives or the adrenal world in which they were before coming back to life.

according to the induced fit hypothesis of enzyme catalysis, _____.
Answer:
the binding of the substrate changes the shape of the enzyme's active site
Explanation:
According to the induced fit hypothesis of enzyme catalysis, the shape of the active site of an enzyme changes in response to the binding of a substrate molecule.
What is induced fit hypothesis of enzyme catalysis?The active site, which is the region of the enzyme that interacts with the substrate, adjusts its shape to fit the substrate more snugly. This change in shape enhances the formation of the enzyme-substrate complex, leading to more efficient catalysis and faster reaction rates.
The induced fit hypothesis suggests that the active site is not a rigid structure, but rather, is flexible and dynamic, adapting to the substrate to optimize the reaction.

using energy to move waste materials out of a cell
Active transport is a type of transport that requires energy to move substances across a membrane. It occurs against a concentration gradient.
The use of energy to move waste materials out of a cell is an EXAMPLE of transport active.Active transport occurs against a concentration gradient, whereas passive transport (i.e., diffusion) occurs in favor of a concentration gradient.Active transport can be mediated by membrane proteins that move substances from an area of high concentration to an area of low concentration.This movement (active transport ) usually requires the energy provided by the hydrolysis of ATP.Water molecules move across cellular membranes through membrane protein channels called aquaporins that act in favor of a concentration gradient (passive transport).

Which of the following is a product of cellular respiration?
Carbon dioxide
Oxygen
Carbon monoxide
Nitrogen
Answer:
it Carbon dioxide and water but Carbon Dioxide was the only one here
Explanation:
The one that is a product of cellular respiration is carbon dioxide. The correct option is A.
What is cellular respiration?Cellular respiration is the process by which biological fuels are oxidized in the appearance of an inorganic electron acceptor such as oxygen to yield huge amounts of energy, which drives the bulk production of ATP.
In plants, photoautotrophic processes are used to obtain the glucose required for cellular respiration. This means that plants can use the light energy they receive from the sun to produce glucose and oxygen.
ATP is the primary product of cellular respiration; waste products include carbon dioxide and water.
All through cellular respiration, one sugar molecule is converted into 38 ATP molecules. The electron transport system actually creates 34 molecules of ATP out of a total of 38 molecules.
Thus, the correct option is A.

Which statement correctly describes how energy is made in photovoltaic cells and how energy is made in photosynthesis?
A.photovoltaic cells can only make energy that does not need light for photosynthesis can only make energy that needs light.
B.photovoltaic cells in photosynthesis can make energy that need light and energy that does not need light. C.photovoltaic cells need light to make energy by photosynthesis to make energy that needs light and energy that does not need light. D.photovoltaic cells can make energy that need light in energy that does not need light for photosynthesis can only make energy that does not need light
Both photosynthesis and photovoltaic cells need light in order to produce energy, though photosynthesis does have a process that can occur in the absence of light, so option C is correct.
Photovoltaic cells are man-made panels that use solar light to create energy. They do this by taking advantage of the natural ability of some materials to absorb the photons in sunlight and use them to release electrons. The release of electrons generates an electric current which produces energy.
Meanwhile, photosynthesis is a naturally occurring process by which plants and a handful of other organisms produce energy. Photosynthesis also requires the presence of sunlight to function. However, photosynthesis also has a dark phase where the chemical reactions continue despite the absence of light. For these reasons, option C is correct whilst the rest are false.

"Blending" genes is associated with:
O Complete Dominance
O Blood Typing
O Incomplete Dominance
O Codominance
Answer:
a
Explanation:
The "blending" of genes is associated with incomplete dominance.
Incomplete dominance occurs when neither of the two alleles in a gene pair is completely dominant over the other.
Instead, the phenotype of the heterozygous individual is an intermediate blend or mixture of the phenotypes associated with each allele. In other words, the traits from both alleles are expressed in a blended or intermediate manner.
For example, in a cross between a red-flowered plant (RR) and a white-flowered plant (WW), if incomplete dominance is present, the resulting offspring (RW) may have pink-colored flowers, which represent a blend of the red and white traits.
Thus, the answer is incomplete dominance.
