Explanation:

Producers are organisms that make their own food; they are also known as autotrophs. They get energy from chemicals or the sun, and with the help of water, convert that energy into usable energy in the form of sugar, or food. The most common example of a producer is a plant.

Plasma resembles serum but has additional protein Fibrinogen.

Fibrinogen is a plasma protein that is naturally produced in the liver and carried to other organs and tissues through the bloodstream. Outside the blood vessel, fibrinogen is converted to fibrin by the enzyme thrombin during thrombus formation and plays an important role in wound healing.

The components of plasma and serum are almost identical, but plasma also contains fibrinogen protein. Serum lacks the clotting protein fibrinogen that is present in plasma because plasma is the liquid part of blood that does not contain cells and serum is the liquid part of blood after clotting (serum). In other words, serum is equal to plasma minus fibrinogen. Therefore, the correct answer to this question is "fibrinogen".

a macromolecule that can exist as linear or cyclized, where it has a polar "head" group and a majority non polar "tail" group is lipid.

The name "lipids" refers to a broad category of naturally occurring substances, which also includes waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E, and K), monoglycerides, diglycerides, phospholipids, and others. Lipids are signalling, energy-storage, and structural components of cell membranes. Lipids are utilised in the food and cosmetic industries in addition to nanotechnology. Lipids can be broadly categorised as hydrophobic or amphiphilic small molecules; the amphiphilic feature of some lipids enables them to form membranes, multi- or unilamellar liposomes, or vesicles in an aqueous environment. The sole or partial sources of biological lipids are the two separate classes of biochemical "building-blocks" or "subunits" known as ketoacyl and isoprene groups.

No, starch is not structural component in plants, rather it is a energy storage unit, which helps the plants to grow and produce food and also provide energy for other vital functions.

The structural component in plants is cellulose, which is found only in plant cells in the cell wall. Since it is stronger in nature, so it helps in maintaining shape of the cells and therefore plants as a whole. Starch on the other hand is a polysaccharide, which is made up of number of monomer units of glucose. These polymeric units are bound together by covalent bonds. When the metabolism of monomer units take place, this provides ATP (Adenosine Triphosphate) molecules. Hence, these starch molecules provides energy to cells.

Nuclear DNA, which makes up the majority of DNA, is located in the cell nucleus, with very little DNA being present in the mitochondria (where it is called mitochondrial DNA or mtDNA). The energy from meals is converted by cellular organelles called mitochondria into a form that cells can use.

DNA frequently consists of two strands that are closely bound to one another rather than being a single strand. These two lengthy strands form a double helix as they wrap around one another. A nucleobase and a portion of the molecule's backbone are included in the nucleotide, which holds the chain together (which interacts with the other DNA strand in the helix). In contrast to a base, which is coupled to a sugar, merely one or two phosphate groups, and a nucleoside, bases are related to one or more phosphate groups, a sugar, and a nucleotide. A polynucleotide is a form of biopolymer made up of several linked nucleotides, such as DNA.

Polysaccharides are used by cells to store energy because they break down easily as they are bound together by covalent bonds to provide energy units in the form of ATP.

Polysaccharides are long chain carbohydrate molecules which are bound together by glycosidic bonds (equivalent to covalent bond). These compounds are mainly polymeric in nature such as cellulose, starch or glycogen. These are energy storing units as enzymes do not act directly upon them, however their monomer units participate in metabolic processes. These compounds have high nutritive value and the positive effects on our immune system. It is because organisms release enzymes which break down polysaccharides into simpler units and the metabolism of this unit produces ATP (Adenosine Triphosphate), which provide energy to cell for its proper functioning.

The mineralized connective tissue known as bone contains four distinct types of cells: osteoclasts, osteocytes, bone lining cells, and osteoblasts

Bone plays an important role in the body by supporting and protecting soft tissues, storing calcium and phosphate, and housing bone marrow. Bone is a highly dynamic organ that is constantly resorbed by osteoclasts and neoformed by osteoblasts, despite its inert appearance. Osteocytes appear to be orchestrators and mechanosensors of this bone remodeling process. Although the function of the cells that line the bone is unclear, it appears that these cells play a significant role in linking bone resorption and bone formation.

Osteoblasts and osteoclasts are the two primary types of cells that are involved in the progression of these processes.

The remodeling process that occurs in bone on a continual basis is an essential component in the preservation of proper skeletal structure and function. As a consequence, the imbalance can be the cause of diseases such as osteoporosis. The process of rebuilding bone involves many different kinds of cells as well as many different variables.

Osteoclasts are the cells responsible for the removal of old bone, while osteoblasts are the cells responsible for the production of new bone. Under physiological settings, there is no change in the balance between resorption and creation. On the other hand, if the equilibrium is thrown off, the structure or function of the bones will be abnormal. There is an increased risk of developing illnesses of bone metabolism, such as osteoporosis and osteopetrosis.

Plants make polysaccharides primarily as a means of storing energy. Photosynthesis, the process by which plants convert light energy into chemical energy, results in the production of glucose.

Plants use some of this glucose for immediate energy needs, such as growth and development, but they also store excess glucose as polysaccharides, such as starch, for later use.

This allows plants to have a reserve of energy to draw from when light is limited or when the plant is unable to photosynthesize, such as during the night or during periods of stress.

Additionally, polysaccharides like cellulose and pectin, are not used as energy storage but instead are used to provide structural support to the cell walls.

Viruses cannot replicate outside of living cells because they lack the cellular organization and independent machinery necessary for reproduction and other metabolic activities. They can only reproduce within the host's living cells, using the host's cellular machinery.

In order for a virus to multiply, it must first infect cells. Susceptibility defines the ability of a cell or animal to become infected. A virus's host range defines both tissue cells and animal species in which it can infect and replicate. Viruses survive outside our bodies because of their structure.

There are three main classes of RNA that are involved in this process: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).

Each of these classes of RNA plays a unique role in the translation of the genetic code into functional proteins.Messenger RNA, or mRNA, is the RNA molecule that carries the genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm, where protein synthesis occurs. It is synthesized by the process of transcription, in which a specific segment of DNA is copied into a complementary RNA molecule.

The mRNA molecule then travels out of the nucleus and into the cytoplasm, where it serves as a template for the synthesis of a specific protein.Transfer RNA, or tRNA, is the RNA molecule that acts as an adaptor between the mRNA and the growing polypeptide chain. Each tRNA molecule carries a specific amino acid at one end and a specific anticodon at the other end. The anticodon is a sequence of three nucleotides that is complementary to a specific codon on the mRNA.

During protein synthesis, the tRNA molecules bind to the mRNA at the codon-anticodon pairing, and transfer the amino acid to the growing polypeptide chain.Ribosomal RNA, or rRNA, is the RNA molecule that makes up the structural components of the ribosome. The ribosome is the complex molecular machine that carries out the process of protein synthesis. It is composed of both protein and rRNA, and is responsible for the recognition of the mRNA and the correct assembly of the amino acids into a functional protein. rRNA acts as a scaffold and catalyzes the peptide bond formation.

Due to the fact that thin, runny lava travels a great distance before cooling and solidifying repeatedly over the course of millions of years, this sort of eruption results in high, level areas rather than cone-shaped ones.

What is lava?

Lava is molten or partially molten rock (magma) that has been ejected onto a planet's surface from its interior, such as a moon. On land or under water, lava may erupt from a volcano or from a crack in the crust, typically at temperatures between 800 and 1,200 °C. Lava is another name for the volcanic rock that results from subsequent cooling.

Lava flows are the discharges of lava that occur during effusive eruptions. Most lava has a viscosity similar to ketchup, or 10,000–100,000 times that of water. Lava exposed to air quickly forms a solid crust that insulates the remaining liquid lava, allowing it to continue flowing for a long distance before cooling forces it to solidify.

When two alleles are dominant, it means that both alleles have the ability to express their corresponding trait or phenotype. This is known as codominance, where both alleles are fully expressed and visible in the offspring.

An example of this is the Mendelian inheritance of flower color in snapdragons, where the allele for red flowers (R) is dominant over the allele for white flowers (r), and the allele for yellow flowers (Y) is also dominant over the allele for green flowers (y).

When a snapdragon plant that is homozygous for red flowers (RR) is crossed with a snapdragon plant that is homozygous for yellow flowers (YY), the offspring will have both red and yellow flowers, this phenomenon is called codominance.

It is important to note that codominance is different from incomplete dominance, where the dominant allele is partially expressed and the recessive allele is not expressed at all, resulting in a blending of the two phenotypes.

The cell is in prophase during mitosis when it is splitting the cytoplasm to produce new cells. Prophase is the first stage of mitosis, and is when the chromosomes condense and become visible.

During prophase, the nuclear membrane breaks down, the centrioles move to opposite sides of the cell, and the spindle fibers begin to form and attach to the chromosomes. The chromosomes are then pulled to opposite poles of the cell, which is called “disengagement”. During this stage, the cytoplasm of the cell is split, and each half of the cytoplasm separates and moves to either side of the cell.

This splitting of the cytoplasm is what will eventually become the two new cells at the end of the cell division process. Prophase is the longest stage of mitosis, and is the most important stage in the cell division process, because it is at this stage that the cell splits and new cells are created.
