The morphological evidence which is shown in fossils to modern animals supports evolution because some dinosaurs, for instance, had feathers and we can obviously see that trait today in birds. The biochemical evidence, which comes in the form of DNA comparison and amino acid similarities, shows that we related closely to monkeys and pigs, which suggests that we have close ancestors to these animals.
Morphological evidence: Physical structures and traits indicate evolutionary relationships.
Biochemical evidence: Genetic and molecular similarities indicate evolutionary relationships.
Evolution is supported by morphological evidence. Scientists can establish evolutionary links by analysing species' anatomy. Homologous structures, which have a common origin but diverse functions, reflect a shared lineage. Comparative examinations of bone structure, limb arrangement, or body plans can reveal evolutionary links.
Biochemical data emphasises genetic and molecular similarities between organisms. Scientists may compare DNA, protein, and other substances at the molecular level. Common ancestry and evolution explain these commonalities. Comparing genetic sequences can show how closely related species are and when they evolved from a common ancestor.

cytochrome c is a protein found in all species, and functions in energy metabolism. the more closely related two different species are,
The more closely related two different species are, the more alike their cytochrome C amino acid sequences are. The cytochrome C is an evolutionarily conserved protein.
The cytochrome C is an evolutionarily conserved protein involved in cellular respiration.
The cytochrome C is a carrier of electrons that acts during the oxidative phosphorylation stage of cellular respiration.
This protein is evolutionarily conserved in species whose cells generate ATP in anaerobic (oxygen presence) conditions, which means that generally synonymous mutations are observed when comparing the amino acids of this protein.

Does the waxy cutie affect where acertain pla y could be grown? Why?
Waxy skin - some leaves have a thick, waxy skin on their surface. This reduces water loss by transpiration . Water storage - some plants, known as succulents, store water in their stems, leaves, roots or even fruits.
The waxy covering on plant leaves, young stems, and fruit is called the "cuticle". ... The purpose of this covering is to help the plant retain water. In arid regions, that is very important. In wetter regions, the waxy coating may help prevent infection by disease organisms.
Plants that grow in arid zones of USDA zones 9 to 11 use waxy leaves to limit transpiration and retain water but also to protect leaves from the frigid temperatures sometimes found in the desert. Trees like the desert willow (Chilopsis linearis) have narrow, waxy leaves and striking purple flowers.

Answer:
I, II, and III.
Explanation:
Immune response may be defined as the type of response generated by the body against the pathogens. The immune response is important to kill the pathogens.
Fever is a type of immune response generated to kill the pathogen by increasing the body temperature. The number of white blood cells of the body increases to fight against the pathogen. The inflammatory response may also generated to kill the pathogen.

in the process of genetic profiling/dna fingerprinting, what is compared between two people/samples?
Answer:
"DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation. A DNA sample taken from a crime scene is compared with a DNA sample from a suspect. If the two DNA profiles are a match, then the evidence came from that suspect." information from a website so reword it a bit and you should be ok.
In the process of genetic profiling/ data fingerprinting, genetic profiling is a process that can be compared between two people/samples.
What is genetic profiling?DNA profiling compares only the most variable sections of DNA, which has an advantage over whole genome sequencing when seeking to identify genetic changes between two individuals.
In the field of biology known as comparative genomics, genome sequences from various species—including humans, mice, and a broad variety of other organisms—from bacteria to chimpanzees are compared.
"DNA fingerprinting is a lab method used to connect biological evidence to a defendant in a criminal investigation. A DNA sample from a suspect is compared to one acquired from a crime scene. The evidence originated from that suspect if the two DNA profiles match.
Therefore, genetic profiling is compared between two people/samples.

describe in detail, the pathway of an oxygen molecule as it moves from the air outside your body, into your blood and to cell in a muscle in your arm
Answer:
The oxygen molecule enters the human body from the mouth or nose and reaches the phraynx and then the larynx, trachea and the bronchus. It then enters the lungs which then the red blood cells takes the oxygen from the blood and carries it to the muscle in the arm.
The pathway of an oxygen molecule from the air outside your body to a muscle cell in your arm involves several sequential steps, including inhalation, gas exchange in the lungs, transportation through the bloodstream, and diffusion into muscle cells.
During inhalation, you breathe in air through your nose or mouth. The air travels through your respiratory system, passing through the trachea (windpipe) and into the bronchi, which branch into smaller tubes called bronchioles. Eventually, the inhaled air reaches the alveoli, tiny air sacs located at the end of the bronchioles in the lungs.
In the alveoli, oxygen molecules diffuse across the thin walls of the air sacs and into the surrounding capillaries. Oxygen diffuses from an area of higher partial pressure (in the alveoli) to an area of lower partial pressure (in the capillaries). Hemoglobin, a protein within red blood cells, binds to the oxygen molecules in the capillaries, forming oxyhemoglobin.
