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.

Use the F=ma triangle to determine the mass of an object accelerating at a rate of 10m/s2 due to a force of 60N that was applied to that object.
Answer:
6
Explanation:
For this question it just takes a little bit of simple algebra. F=MA is an equation that will pop up again if you continue with an interest in science. F=MA actually say force=mass(acceleration). Which then is changed for this problem to M=F/A.

Answer:
(A) Birds are endothermic and have four-chambered hearts, while reptiles are ectothermic and have three-chambered hearts.
Explanation:
got it right on the test
Birds and reptiles both belong to the animal kingdom. Reptiles are ectothermic and have three-chambered hearts, whereas birds are endothermic and have four-chambered hearts. Thus, option A is correct.
What are the characteristics of birds and reptiles?Birds and reptiles both belong to the kingdom Animalia and are chordates. They both have vertebral columns and the presence of the backbone. They share many similarities and differences in their physical appearances.
The birds are endothermic and can maintain constant body tempearture regardless of the external environment. While reptiles are ectothermic (cold-blooded) and regulate their temperature based on the external environment.
The birds have four-chambered hearts like mammals that separate the oxygenated from the de-oxygenated blood, whereas the reptiles have three-chambered hearts with one ventricle and two atria.
Therefore, the birds are endothermic, and reptiles are ectothermic.
