Glucose polymerizes to form starch or carbohydrates by condensation.

Glucose is a monomer that contains six carbon atoms. We know that both starch and carbohydrates are all macromolecules. This implies that they are formed by the linkage of smaller molecules.

As a macromolecules, several glucose molecules are joined together in a long chain. This sort of chain could be obtained for both glucose and starch and the number of monomer units run into thousands of molecules.

In this case, the smaller molecules that are linked are the glucose molecules. This occurs by the process of condensation. There is a molecule of water lost as the glucose molecules are agglomerated together to form glucose or carbohydrates.

D. Reuptake helps to absorb neurotransmitters into presynaptic neuron.

Substances that neurons utilize in communicating with one another are called Neurotransmitters. When an action potential reaches the terminal, presynaptic neurons release neurotransmitters. The neurotransmitter diffuses across the synapse and attaches to post-synaptic cell receptors. Reuptake or the reabsorption of a neurotransmitter occurs when a neurotransmitter transporter found at the pre-synaptic neuron at a synapse or along the axon terminal plasma membrane or along a glial cell has completed its job of sending a neural impulse.

When a neurotransmitter is broken down by an enzyme into smaller inactive products, which are subsequently reabsorbed by the presynaptic neuron and resynthesized into active neurotransmitter, this might result in reuptake.

Autotrophs: use photosynthesis.

What are Autotrophs?

Autotrophs are living things that can make their own nourishment from inorganic resources. The roots of the terms "autotroph" are "self" and "troph," which refer to nourishment. An autotroph is an organism that can sustain itself entirely without the help of other living things.

Because they are necessary for the existence of all other life forms, autotrophs are very significant. For instance, there would be no herbivorous animals and no carnivorous creatures that consume herbivores if there were no plants that used carbon dioxide gas and sunshine to produce carbohydrates. Autotrophs are frequently referred to as "producers" because of this. They give the energy that all heterotrophs (organisms that must obtain their food from others) need in order to thrive, and they are the foundation of an ecosystem's energy pyramid.

Correct answer is E. It is single-stranded.

DNA and RNA vary primarily in that whereas RNA has single-stranded molecules, DNA contains double-stranded ones. Deoxyribonucleic acid, also known as DNA, and ribonucleic acid, also known as RNA. Genetic information is carried by both DNA and RNA, but there are several key distinctions between the two. Deoxyribose, a sugar, makes up DNA, while ribose, a sugar, makes up RNA. Deoxyribose has one less -OH group than ribose. Another distinction is that whereas RNA is not stable in an alkaline environment, DNA is.

All genetic information is encoded in DNA, which also serves as the building block for all biological life. And only in the near future. In the long run, DNA serves as a storage medium, a biological flash drive that enables the transmission of the genetic code from one generation to the next. RNA works as the reader that decodes this flash drive. There are distinct RNAs for each phase in this multi-step reading process. We examine the three most crucial RNA kinds in further detail below.

On average, leaves and other surfaces reflect between 98 and 99 percent of the solar energy that enters the Earth. These reflections are then absorbed by other molecules, who then turn the energy into heat. Only 1 to 2 percent is therefore available for plants to absorb.

Plants use a region of the light spectrum called photosynthetic active radiation (PAR), or light with wavelengths between 400 and 700 nanometers, for photosynthesis.

Only around 10% of the energy is transferred to the following trophic level as a result. The ecosystem has a particular energy flow.

Therefore, only 2%  solar energy is captured by the cells of photosynthetic organisms.

Structures called the perforating canals house blood vessels that carry blood from the medullary cavity and periosteum to the osteon.

The blood vessels that go via the central canals can link to the blood vessels in the periosteum that covers the bone through perforating canals, which act as conduits. Trabeculae, or thin, atypically formed plates, are organised in a latticework network to make up trabecular bone.

Osteocytes are found in lacunae that are located in between calcified lamellae in trabeculae, just like osteons are in osteons. Similar to osteons, trabeculae have canaliculi that link the osteocytes. However, each osteocyte can exchange nutrients with neighboring blood vessels since each trabecula is only just a few cell layers thick. Therefore, a central canal is not required.

Therefore, perforating canals house blood vessels that carry blood vessels from the medullary cavity and periosteum to the osteon.

Answer:

S phase

Explanation:

In the eukaryotic cell cycle, chromosome duplication occurs during "S phase" (the phase of DNA synthesis) and chromosome segregation occurs during the "M phase" (the mitosis phase). During S phase, any problems with DNA replication trigger a ‘'checkpoint" — a cascade of signaling events that put the phase on hold until the problem is resolved. The S phase checkpoint operates like a surveillance camera; we will explore how this camera works on the molecular level. The last 60 years of research in bacterial species (specifically, Escherichia coli) and fungal species (specifically, Saccharomyces cerevisiae), have continually demonstrated that several major processes during DNA replication are evolutionarily conserved from bacteria to higher eukaryotes.

Amongst the array of proteins at the replication fork, DNA polymerases are central to the process of replication. These important enzymes can only add new nucleoside triphosphates onto an existing piece of DNA or RNA; they cannot synthesize DNA de novo (from scratch), for a given template. Another class of proteins fills this functional gap. Unlike DNA polymerases, RNA polymerases can synthesize RNA de novo, as long as a DNA template is available. This particular feature of de novo synthesis is similar to what happens during mRNA transcription.

We have to add s phase in the process of cell cycle at which the enzyme DNA polymerase have the significant role.

Cell cycle is the process of regenerating new cells by dividing the existing cell through several stages namely prophase, telophase, s-phase etc. Both prokaryotes and eukaryotes undergo cell division and produce the identical daughter cells.

Between G1 phase and G2 phase, the cell cycle's S phase (also known as the "synthesis phase") is when DNA replication occurs. [1] Since precise genome duplication is essential for effective cell division, the S-phase mechanisms are strictly regulated and highly conserved.

One nucleotide at a time, DNA polymerase adds nucleotides to the three prime (3')-end of a DNA strand. DNA polymerases are necessary to replicate the cell's DNA during cell division in order for a copy of the original DNA molecule to be transferred to each daughter cell. Genetic information is transmitted in this manner from one generation to the next.
