Scientists compare the structures of a chicken embryo and a human embryo at the same stage of development. They find that both vertebrates have
similar shapes and structures, including the presence of gill slits and tails. How is this comparison of the embryos used as supporting evidence of
evolution?
The similarities suggest that chickens and humans are the direct descendants of modern-day fish with tails and gill slits.
The similarities suggest that vertebrates pass through each of the adult stages of their evolutionary history as they develop.
o
The similarities suggest that vertebrates can undergo genetic changes during development that lead to the evolution of new species.

Chromatin determines the unique traits of an organism. Chromatin allows number of cell processes to occur including DNA replication, transcription, DNA repair, genetic recombination and cell division.

Chromatin fibers are coiled and condensed to form the chromosomes and it is a genetic material or a macromolecule comprising DNA, RNA, and associated proteins, which constitutes chromosomes in the nucleus of eukaryotic cell. The chromatin is located within cell nucleus. Main functions of this genetic material includes: Preventing DNA damage.

Its functions are to package DNA into smaller volume to fit in cell, strengthen DNA to allow mitosis and meiosis, and serve as mechanism to control expression.

Answer: It determines the traits of an organism.

Explanation:

Angles that are immediately across from one another on intersecting lines are known as vertical angles.

A place to start. An angle is produced when two rays come together at a single point. The common point is referred to as the node or vertex, while the two rays are known as the arms of the angle.  The word "angle" has its roots in the Latin word "Angulus."

In geometry, there are three basic kinds of angles: acute angles, which have a degree range of 0 to 90. A 90° angle, or the right angle. Obtuse angles are those between 90 and 180 degrees. Zero angles are those that have a measure of zero degrees or zero radians. The zero angle does not have a unit of measurement. An angle is produced when two angle arms having a common vertex are stacked on top of one another.

As a result, they are equivalent and have a same vertex. Only DCE and BCA are vertical angles among these pairings since they share the vertex at point C and are located across from one another on the lines FJ and IM.

A homozygous gene is a gene in which both alleles are identical.

This means that an individual with a homozygous gene will have the same version of the gene on both chromosomes. For example, if an individual has two copies of the "A" allele for a particular gene, they would be homozygous for that gene. An individual who is homozygous for a genomic marker has two identical versions of that marker. On the other hand, a heterozygous gene refers to a gene in which an individual has two different alleles for a particular gene. This means that the individual will express a combination of the traits or characteristics associated with each allele.

Energy and pyruvate are the byproducts of the breakdown of glucose. The particular form of glucose used in glycolysis is glucose 6-phosphate.

The final product of glycolysis is pyruvate, which is then converted into energy and two ATPs (Glucose + two NAD+, two ADP, and two pi = two pyruvate, two NADH, two H+, two ATP, and two molecules of water). In order to phosphorylate, the hydroxyl groups are necessary. Glycolysis uses glucose 6-phosphate as a particular type of glucose.

In aerobic and anaerobic environments, the end result of glycolysis is pyruvate, respectively. The Krebs cycle is activated by pyruvate to produce more energy. For cells, ATP serves as a form of currency. It enables cellular transport and short-term energy storage for endergonic chemical processes.

The next person to classify grouping animals and plants by similar characteristics after Carl Linnaeus was Jean-Baptiste Lamarck.

Jean-Baptiste Lamarck was a French naturalist who proposed a system of classification based on a hierarchical arrangement of organisms, grouping them together by their similarities and differences. He is known for his proposal of a "theory of descent with modification" which stated that organisms could evolve over time through the inheritance of acquired characteristics and natural selection, which would be later popularized by Charles Darwin.

Lamarck's classification system, known as Lamarckism, was a significant contribution to the field of biology and was influential in the development of the modern system of classification used today. He proposed a system that recognized the animal kingdom into two groups: the first one was composed of animals with backbones, and the second of those without, this was a more accurate system than the one proposed by Linnaeus.

It's worth noting that Lamarck's theories were later largely discredited by the scientific community because of the lack of evidence and the discovery of the mechanism of genetics and the Mendel's laws of inheritance, but his contributions to the classification of living organisms has been recognized as important and his impact on the field of biology cannot be underestimated.

Answer:

Coke is a type of fuel made by heating coal in the absence of air. This process, known as coking, produces a solid fuel that has a higher energy content and is more efficient to burn than coal alone. Coke is used in metallurgical and industrial processes, such as smelting and steel production.

The coking process was first developed in 18th century England, and is still used today. To make coke, coal must be heated in an oxygen-free environment to temperatures of up to 1,000 degrees Celsius. The heat breaks down the coal, releasing volatile compounds and leaving a carbon-rich residue. This residue, or ‘coke breeze’, is then cooled and formed into large bricks.

The coking process has changed over the years, with new technologies being developed to reduce the amount of time and energy needed for the process. Today, ‘retorting’ is a common technique used to make coke. In this process, the coal is placed in an air-less container and heated to temperatures of up to 1,200 degrees Celsius. This process produces a higher-quality product and reduces the amount of time needed for the process.

The dominant trait appears three times as frequently as the recessive trait in the F2 generation, which always produces a 3:1 ratio.

Mendel used two phrases to describe how the two phenotypes based on the F1 and F2 phenotypes related to one another.The phenotype that is displayed in the F1 generation from the cross of two pure lines is known as the dominant allele because it expresses itself at the expense of an alternate allele.

The trait that vanishes in the F1 generation from the cross of two pure lines and return in the F2 generation is known as a recessive allele, which is an allele whose expression is repressed in the presence of a dominant allele.

Mendel frequently noted a 3:1 phenotype ratio in the F2 generation, or the progeny of monohybrid crossings, where three plants had the dominant phenotype and one plant had the recessive phenotype. Mendel anticipated that the plants in the F2 generation with dominant phenotypes would be heterozygous genotype Aa in some cases and homozygous genotype AA in others.
