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.

how is the scientific method used in earth science (it was due yesterday)
Answer: The steps used in scientific methods are to ask a question, form a hypothesis, test the hypothesis, analyze the results, draw conclusions, and communicate results. A controlled experiment tests only one factor at a time so that scientists can determine the effects of changes to just that one factor.
Answer:
The scientific method is the gold standard for exploring our natural world. You might have learned about it in school, but here’s a quick reminder: It’s the process that scientists use to understand everything from animal behavior to the forces that shape our planet—including climate change.

What is global warming?:
[tex] \bigstar \underline{ \large{ \sf{ \pink{Global \: \: Warming}}}} : [/tex]
▶ Global warming can cause sea levels to rise dramatically. In many places, coastal areas have already been flooded. Global warming could result in wide ranging effects on rainfall patterns, agriculture, forests, plants and animals. Majority of people living in regions which are threatened by global warming are in Asia. A recent climate change report gives us only a limited time to keep the greenhouse gases at the present level. Otherwise, the temperature may rise by more than 2 degrees Celsius by the end of the century, a level considered dangerous.______________________________

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.

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.

What is Respiratory System?The respiratory system is the network of organs and tissues which helps with breathing that includes the airways, lungs, and blood vessels. The muscles that power the lungs are also part of the respiratory system. They work together to move oxygen throughout the body and to clean up waste gases like carbon dioxide.
Respiratory system consists of following parts like
Nose--> Mouth--> Pharynx --> Larynx --> Trachea --> Bronchi --> Bronchioles --> Alveoli
The respiratory system has many functions others than inhaling (breathe in) and exhaling (breathe out), it:
It allows talking and smelling.It warms the air to match the body temperature and moisturizes it to the moisture level the body needs.It transports oxygen to the cells in your body.It removes waste gases, including carbon dioxide, from the body when you exhale.It protects the airways from harmful substances and irritantsThus, following are the parts of Respiratory system:

Answer:
F1 Generation
Explanation:
In the study of genetics the offspring of the P generation is referred to as the F1 generation.
In the study of genetics, the offspring of the P generation are referred to as the F1 offspring, or first fillial offspring. Their genetic makeup depends on their parents.
What is inheritance?Inheritance explains how the genes from the parents pass down to the offspring. An example is when both parents are tall because they are purebred, then all the F1 offspring are tall.
The T is represented by tall, and the t is represented by short. TT is purebred tall, and tt is purebred short. When two parents (P generation) are heterozygous for tallness, such as Tt, each will produce gametes such as T and t. From these gametes, three types of individuals are formed, such as purebred tall (TT), heterozygous tall (Tt), and purebred short (tt). These are called F1 offspring.
Hence, in the study of genetics, the offspring of the P generation are referred to as the F1 offspring, or first fillial offspring.

2. Body cells undergo the process of mitosis while gametes undergo a process called meiosis.

5. A gene is a sequence of nucleotide bases that specifies certain products; RNA or proteins. It is the segment of DNA that holds the information to build and maintain an organism's cell and also pass genetic traits to offspring. Hence, it is the molecular unit of heredity in living organisms.
The DNA is a long double-helical structure that stores the genetic information in our cells. It consists of two long polynucleotide chains composed of the four nucleotides subunits (A, C, G, T).
In order for the long strand of DNA to fit into the cell's nucleus, it is coiled around certain proteins called HISTONES to form Chromatin, which undergoes further coiling and organization to to linear CHROMOSOMES.
The chromosomes are structured within the nucleus, that are made up of the cell's genetic material (DNA). In eukaryotic cells, the nucleus houses the cell's DNA and directs protein synthesis (expression of the information encoded by genes).

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.
