The current level of folic acid fortification of grain products leads to an intake of about 100 extra micrograms of folic acid per day. Why doesn’t the fortification program mandate higher levels of folic acid to more effectively meet requirements?.
The amount of folic acid added to grain products at this time results in an additional daily consumption of roughly 100 micrograms. Because too much folic acid might conceal a vitamin B-12 deficiency, the fortification programme does not need greater doses of folic acid.
Malabsorption of food-bound vitamin B12 is the most frequent cause of vitamin B12 deficiencyin elderly individuals. Therefore, it is advised that the 2.4 microg/d recommended daily requirement be predominantly reached by crystalline vitamin B12, which is thought to be well absorbed in people with food-bound malabsorption.
There is worry that increased folic acid intakes from fortified foods and nutritional supplements might conceal the macrocytic anaemia caused by vitamin B12 deficiency, obviating a crucial diagnostic indicator.

The lactose (lac) operon in e. Coli is an example of a gene that is expressed when lactose is not available in a cell.
The given statement is false that the lactose (lac) operon in E. coli is an example of a gene that is expressed when lactose is not available in a cell.
Lactose operon is the set of genes present in the prokaryotic cells that work together in order to conduct the metabolism of lactose. The genes of the operon are expressed when lactose is present and glycose is absent in the cell.
Gene is the most basic and fundamental unit of heredity. it is the factor that contains the information for a particular trait. It is present on the chromosome at a certain specific location. There are several genes present in the living organism's genetic material that code for various traits.

What type of body symmetry do animals in phyla Platyhelminthes, Annelida, and Nematoda have?
-bilateral symmetry
-radial symmetry
-asymmetry and radial symmetry
-asymmetry
Phyla Platyhelminthes, Annelida, and Nematoda have bilateral symmetry.
What is symmetry?
A property of some organisms in biology known as symmetry is the uniformity of parts on a plane or around an axis. A symmetrical creature would have an even distribution of duplicate parts on either side of the axis (indicating symmetry). It could not be an exact replica but rather a close repetition. Bilateral symmetry is an illustration of symmetry in living things.What is bilateral symmetry?
A type of symmetry in which the opposing sides are similar is known as bilateral symmetry. In a sagittal plane, the outside look is identical on the left and right sides (such as the body plan of most animals, including humans). An organism's body plan can be divided into equal mirror halves in the sagittal plane when it exhibits bilateral symmetry. Organs and other internal body parts may not always be symmetrical. Animals that have bilateral symmetry belong to the taxonomic group Bilaterian. These animals, which are also known as bilaterians, have left and right sides to set them apart from species with other types of symmetry (such as radial symmetry) and those without symmetry (asymmetry).Hence, Phyla Platyhelminthes, Annelida, and Nematoda have bilateral symmetry.

Local block on the postsynaptic side generally just blocks all channels botulinum doesn't affect action potential but does affect what goes through the cell.
Local anesthetics stop nerves in parts of the body that send signals to the brain. You won't feel any pain after the local anesthesia, but you may feel some pressure or movement. It usually takes only a few minutes for the area where the local anesthetic is administered to lose sensation.
Local anesthetics such as novocaine block neurotransmission to pain centers in the central nervous system by binding to and inhibiting the function of ion channels in the cell membranes of nerve cells called sodium channels. Local anesthetics can block the transmission of nerve impulses along all types of nerve fibers.

What is the function/job of the digestive and respiratory systems?
Answer: The digestive system is responsible for breaking down food and absorbing nutrients from it, while the respiratory system is responsible for bringing oxygen into the body and removing carbon dioxide.
Explanation:
The digestive system consists of a number of organs that work together to process food and extract nutrients from it. These organs include the mouth, esophagus, stomach, small intestine, large intestine, and rectum. The digestive system starts with the mouth, where food is mechanically broken down by chewing and mixed with saliva, which contains enzymes that begin the process of breaking down food. The food is then swallowed and passes through the esophagus, which moves it to the stomach, where it is mixed with stomach acid and enzymes that continue the process of breaking down the food. The partially digested food is then moved to the small intestine, where it is further broken down and the nutrients are absorbed into the bloodstream. The remaining indigestible material is moved to the large intestine, where water is absorbed and the material is eliminated through the rectum.
The respiratory system consists of the nose, mouth, pharynx, larynx, trachea, bronchi, and lungs. When we inhale, air passes through the nose or mouth, down the pharynx and larynx, and into the trachea. The trachea then splits into two bronchi, which lead to the left and right lungs. The lungs are made up of tiny air sacs called alveoli, where oxygen from the air we inhale is exchanged with carbon dioxide from the body's cells. The oxygen-rich blood is then carried back to the heart, where it is pumped to the rest of the body. When we exhale, the carbon dioxide is expelled from the body.

The option that does not possess the ability to synthesize its own protein is: a virus.
Proteins are the biomolecules that are necessary for the living body to perform multiple functions. A protein is polymers made up of amino acid monomers. The functions that proteins can perform are varying like: signaling, enzymatic, transport, structural, etc.
Viruses are the acellular components. They are called acellular because they do not follow the cell theory. Viruses do not function outside any living body. However once inside any living host, they exhibit the potential to takeover the machinery of the cell they are present in and synthesize their own viral particles or proteins.

Which mutation could be passed on to future generations?
A. A nerve cell has an adenine substituted for a guanine base on one of its chromosomes
B. A strand of mRNA has a mistake in it that was not in the original DNA strand
C. A sperm cell has an extra nucleotide on chromosome 23 that was not in the parent cell
D. A strand of replicated DNA in a liver cell has a mistake on it that wasn’t in the original DNA strand
The mutation that could be passed on to future generations is option C, in which a sperm cell has an extra nucleotide on chromosome 23 that was not in the parent cell.
Mutations are changes to the genetic material of a cell that can potentially be passed on to future generations. These changes can occur in the DNA of an organism's cells, as well as in the RNA molecules that are transcribed from DNA.
In option A, a nerve cell has an adenine substituted for a guanine base on one of its chromosomes. This is an example of a point mutation, in which a single nucleotide is changed within a strand of DNA. However, this mutation is not likely to be passed on to future generations, as it occurred in a nerve cell rather than in a reproductive cell.
In option B, a strand of mRNA has a mistake in it that was not in the original DNA strand. This is an example of a transcription error, in which a mistake is made during the process of transcribing DNA into RNA. However, this mutation is also not likely to be passed on to future generations, as it occurred in an RNA molecule rather than in DNA.
In option C, a sperm cell has an extra nucleotide on chromosome 23 that was not in the parent cell. This is an example of a chromosomal mutation, in which a change occurs in the structure or number of chromosomes in a cell. Because this mutation occurred in a sperm cell, it has the potential to be passed on to future generations through sexual reproduction.
In option D, a strand of replicated DNA in a liver cell has a mistake on it that wasn’t in the original DNA strand. This is an example of a replication error, in which a mistake is made during the process of copying DNA strands. However, like options A and B, this mutation is not likely to be passed on to future generations
