A snake is a long, limbless reptile with a short tail and jaws that may extend to a great extent. A lizard is a reptile that normally has four legs, a long body and tail, moveable eyelids, and a rough, scaly, or spiny skin.
So, this is the main distinction between lizards and snakes. There are two categories of reptiles: lizards and snakes. Both are members of the Squamata order. They both have distinctively lengthy bodies. Additionally, both have dry skin that is scale-covered. And both have a heart that has three chambers—two atria, one ventricle. They are both cold-blooded creatures as well. They thus heat their bodies from outside sources. Both are oviparous as well. They do so by laying eggs. They are both carnivores as well.

How is protein made using the information from amino acid?
A complex collection of molecules known as ribosome it is used by cells to assemble proteins. The ribosome puts amino acids in the correct order and connects them with peptide bonds. A polypeptide chain—a lengthy collection of amino acids—is produced by this procedure, known as translation.
Which proteins are produced using amino acids?Amino acids unite to form peptide bonds, which are another name for proteins known as polypeptides. Depending on the interactions (dashed lines) between the side chains of the polypeptide's amino acids, the polypeptide will then fold into a particular shape.
Are amino acids present in all proteins?All proteins are made up of one or more chains of amino acids, despite the fact that their shapes, as well as their functions, vary widely.

DNA replication is a necessary process associated with the cell cycle. Which of the following statements best identifies when DNA replication occurs and why it is important.
a) during cell division, to ensure that the DNA will fit into the resulting cells
b) after a cell divides, to provide each of the two resulting cells with a complete set of DNA instructions
c) before a cell divides, to provide each of the two resulting cells with a complete set of DNA instructions
The statement that best identifies when DNA replication occurs and why it is important is as follows: before a cell divides, to provide each of the two resulting cells with a complete set of DNA instructions (option C).
What is DNA replication?DNA replication is the process by which DNA makes a copy of itself during cell division.
DNA replication occurs during the interphase stage of cell division, specifically in the synthesis (S) phase.
The first step in DNA replication is to ‘unzip’ the double helix structure of the DNA molecule. This is carried out by an enzyme called helicase which breaks the hydrogen bonds holding the complementary bases of DNA together (A with T, C with G).
The separation of the two single strands of DNA creates a ‘Y’ shape called a replication ‘fork’. The two separated strands will act as templates for making the new strands of DNA.
Replication of DNA is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.
Therefore, option C is the correct answer.

how did mendels experiments with peas convince him that there were disfuct units of heritance that were not blended together in the offspring
Mendel conducted this well-known experiment in which he purposely cross-pollinated pea plants based on their many characteristics in order to learn crucial truths about how traits are passed down through the generations.
What is Mendel's experiment?Because he noticed that specific features were regularly and predictably passed from one generation to the next, Gregor Mendel was convinced by his studies with peas that there were discrete units of heredity, today is known as genes.
For instance, he discovered that the progeny of crosses between purebred pea plants with tall stems and those with short stems all produced long stems. But when he let these kids self-pollinate, around three-fourths of the offspring had tall stems, while roughly one-fourth had short stems.
Therefore, Mendel's research served as the cornerstone for the modern understanding of genetics and the function of genes in inherited traits.

How are proteins made using the information found in the DNA?
The sandwich-like arrangement of ribosomal subunits on the strand of mRNA that occurs during translation allows them to draw in tRNA molecules bound to amino acids (circles). The ribosome transforms the decoded mRNA sequence into a polypeptide, or new protein, into a lengthy chain of amino acids.
Ribosomes are located where?Depending on whether the cell is from a plant, an animal, or a bacterium, ribosomes are usually found attached to the endoplasmic reticulum and the nuclear envelope, as well as freely dispersed throughout the cytoplasm.
For the purpose of protein synthesis, the mRNA is produced in the nucleus and moved to the cytoplasm. In the cytoplasm, mRNA polymers are wrapped with the ribosomal subunits. Proteins are then created by the tRNA. The building of proteins occurs on ribosomes.

The haploid number of chromosomes of a plant is 20. the number of chromosomes in root, stem, and leaf cells would be?
The number of chromosomes in root, stem, and leaf cells would be 40.
Chromosomes are thread-like structures made of protein and a single DNA molecule that transport genomic information from cell to cell. Chromosomes are found in the nucleus of cells in plants and animals.
A chromosome is a long DNA molecule that contains all or part of an organism's genetic material. Most chromosomes have very long thin DNA fibers coated with packaging proteins; the most important of these proteins in eukaryotic cells are the histones.
Genetic diversity is greatly influenced by chromosomal recombination during meiosis and subsequent sexual reproduction. If these structures are incorrectly manipulated, as with chromosomal instability and translocation, the cell may undergo mitotic catastrophe.
Normally, this causes the cell to initiate apoptosis, which leads to its own death, but mutations in the cell can impede this process and thus cause cancer progression.
