It is possible that the small animal ate some sort of grass and the strict vegetarian did as well. So the Carbon atom originally in the stomach of the small animal came out when the animal breathed out, landed on the grass blades, and the strict vegetarian ate the blades of grass and consumed the carbon atom as well.
What is Carbon atom?Carbon atom is a chemical element with symbol C and atomic number 6. Carbon atom is a non-metal and is tetravalent.That atom donates four electrons to form a covalent chemical bond. It is present in the group 14 of the periodic table. Carbon atom makes up only about 0.025% of the Earth's crust. Carbon atom has two electron shells, the first shell holds two electrons and the second shell holds four of the eight possible positions.When atoms bond, they share electrons in their outermost shells. In the outer carbon shell he has four vacancies that allow him to bond with four other atoms of her. But perhaps more important is the ability of carbon to form covalent bonds. Carbon atoms can form covalent bonds with up to four other atoms, making them suitable for forming the basic structure or “backbone” of macromolecules.To learn more about Carbon atom from the given link :

sexual selection in males usually results in an increased ability to for mates, whereas sexual selection in females usually involves a mate with the best fitness
Disparities in mate attraction that alone account for differences in reproductive success An important aspect of evolutionary biology is sexual selection. The nature and scope of sexual selection, however, have been debatable since Darwin first proposed the idea of it.
Recent debate has brought the fundamental topic of what sexual selection actually is back into focus. Incorporating female-female reproductive rivalry into sexual or natural selection is one example of this.
Sex roles are determined by differences in gametes: men generate significantly more plentiful, smaller, motile gametes whereas females produce relatively fewer, more nutritious, often non-motile gametes. There will be an excess of male gametes that will not fertilize any eggs since just one gamete of each kind is necessary to generate a child.

molecular data lends itself to distance-based phylogenetic methods because it is relatively simple to count up differences between sequences that have been
Distance-based approaches build trees depending on how different the two sequences are from one another. They need substantially less computing than character-based approaches and are often correct since they count mutations.
Such information is used by molecular phylogeny to create a "relationship tree" which depicts the likely evolution of distinct creatures. Sanger sequencing was developed in 1977, making it feasible to separate and recognize these chemical sequence. A matrix with pairwise distances was initially used to analyze phenetic data before being used to non-parametric distance techniques in phylogeny. The result of balancing these distances is a tree ( with informative sequence lengths). In the relatively young field of molecular phylogeny, evolutionary connections, histories, and in some cases even functions are inferred via the comparative examination of the amino acid and nucleotide sequences of proteins, as well as their structural characteristics.

What are the 3 elements of gene expression?.
The 3 elements of gene expression: Regulation of transcription can be broken down into three main routes of influence;
genetic (direct interaction of a controlling factor with the gene), modulation interaction of a controlling factor with the transcription machinery, and epigenetic (non-sequence changes in DNA structure that influence transcription).
Genes are composed of deoxyribonucleic acid (DNA), except for some viruses, which have genes that include a carefully associated compound called ribonucleic acid (RNA). A DNA molecule consists of two chains of nucleotides that wind approximately every different to resemble a twisted ladder.
Gene expression is the system of turning on a selected gene to begin making messenger RNA. The messenger RNA can then perform intended jobs inside the cell, such as forming proteins. Gene expression controls both whether or not the messenger RNA is made, as well as how a whole lot of messenger RNA is made at that time.

How are Chondrichthyes structured?The skeletons of all members of the Chondrichthyes lack true bone and are instead made of cartilage. Only their teeth and occasionally their vertebrae have calcified cartilage, and this calcified cartilage is not the same as true bone.
The skeleton of cartilaginous fish, also known as Chondrichthyes in science, is made of cartilage rather than bone.

from the following compounds involved in cellular respiration, choose those that are the net inputs and net outputs of glycolysis.
In a linear metabolic process involving enzyme-catalyzed reactions, known as glycolysis, glucose is converted into two molecules of pyruvate when oxygen is present or into two molecules of lactate when oxygen is not present.
Net Input: ADP, NAD⁺, Glucose
Net Output: ATP, NADH and Pyruvate,
not input or output: O₂, CO₂, coenzyme A and acetyl CoA
Anaerobic glycolysis, the latter route, is thought to be the first mechanism to have arisen in nature that produces adenosine triphosphate (ATP). In the majority of cells, glycolysis turns glucose into pyruvate, which mitochondrial enzymes then oxidize to produce carbon dioxide and water. However, due to the absence of mitochondria in some cells, most notably adult red blood cells, glycolysis serves as the only method of ATP synthesis. Glycolysis is the only method available to cells for converting glucose into ATP in the absence of oxygen. Lactic acidosis, a potentially fatal disease, is brought on by anaerobic glycolysis' excessive lactic acid generation. Numerous cancer cells have an incredibly high glycolytic enzyme capability. Cancer cells use glycolysis to make a large portion of their ATP even when oxygen is present.

In glycolysis, hexokinase dephosphorylation prevents the transport of glucose back out of the cell.
How hexokinase dephosphorylation prevents the transport of glucose back out of the cell?With the help of ATP, hexokinase dephosphorylates glucose, resulting in a nonpolar glucose molecule that cannot pass through the hydrophilic region of the plasma membrane.
When glucose is phosphorylated by hexokinase utilising ADP, a polar glucose molecule is produced that cannot pass through the hydrophobic core of the plasma membrane.
The nonpolar glucose molecule produced by hexokinase's dephosphorylation of glucose using ADP is unable to pass the hydrophilic region of the plasma membrane.
