Choking on food is most likely caused by an interference with the proper functioning of the...
Answer:
esophagus
Explanation:
the esophagus is the pipe/muscle that leads to your stomach
Choking on food is most likely caused by an interference with the proper functioning of the oesophagus.
What is oesophagus?
The digestive system, sometimes known as the gastro-intestinal tract, includes the oesophagus (gullet) (GI tract). An oesophageal tube is made of muscles. It joins the mouth with the stomach.
The oesophageal walls contract together as you swallow food (contract). This causes the food to travel from the mouth to the stomach.
The diaphragm is a layer of muscle located below your lungs. It facilitates breathing. The majority of your oesophagus is located in your chest above the diaphragm.
Therefore, Choking on food is most likely caused by an interference with the proper functioning of the oesophagus.

Explanation:
Would a volcanic eruption affect Earth’s climate?Justify your response.
Answer:
Explanation:
The gases and dust particles thrown into the atmosphere during volcanic eruptions have influences on climate. Most of the particles spewed from volcanoes cool the planet by shading incoming solar radiation. The cooling effect can last for months to years depending on the characteristics of the eruption.
Which of the following are techniques besides molecular clocks used by scientist to calculate the rate at which a stretch of DNA changes? (Choose all that apply)
•comparison of human behaviors
•carbon dating of fossils
•comparison of blood proteins
•comparison of homologous structures
Answer:
B and D
Explanation:
Human behaviors do not affect the entire evolution of every lifeform that has existed, therefore, A is FALSE
Carbon dating is commonplace in figuring out how old a lifeform could be, therefore, B is CORRECT
Blood proteins are commonly known to not last long and decompose fast, so fossilization of blood tends to not happen, plus it's next to impossible to tell what species had that genetic data, therefore, C is FALSE
For D, I kinda forgot most of my explanation, but I remember that it's correct, as I got the question correct on the assignment.
The carbon dating of fossils and comparison of homologous structures are techniques besides molecular clocks used by scientist to calculate the rate at which a stretch of DNA changes.
So, option B and D are correct one.
Human behaviors do not affect the entire evolution of life of organism that has existed, therefore, A is FALSE
Carbon dating is commonplace in figuring out how old a life of any organism, therefore, B is CORRECT
Blood proteins are commonly known to not last long and decompose faster, so fossilization of blood tends to not happen, plus it's next to impossible to tell what species had that genetic data, therefore, C is FALSE
By comparing of homologous structures we determine nucleotide sequence exchanged between two similar or identical molecule of DNA. So, option D is correct
What is Carbon dating?It is also referred as radiocarbon dating.It is the method used to determine the age of the living organism containing organic( carbon ) based material by using isotopes of carbon which is radioactive.Learn about carbon dating

The other three options basically are the cell theory!
The cell theory states that:
The basic units of life are cells.All cells arise from other pre-existing cells.All living things are made of cells.Since the 3 options state this, the first option (that all of them are part of the theory) should be correct.

What is the importance of neutral variation in evolution?
A trait that is neutral in one environment may be advantageous in another.
It is usually removed from the population by natural selection due to its deleterious phenotypes in the environment.
A trait that is neutral will most likely be removed from the gene pool.
It will cause for a population to risk decline and extinction.
Answer:
A trait that is neutral in one environment may be advantageous in another.
Explanation:
Neutral variation refers to the variation (either genetic or phenotypic variation) which is unaffected by natural selection. Neutral variation is known to increase genetic variation, which is a prerequisite to evolutionary change. An allele may be neutral in one environment and beneficial (or deleterious) in another. In consequence, neutral variation in one environment may increase the response to selection in different environmental conditions.

Answer:
1) Gravitational force is an attraction between masses. The greater the size of the masses, the greater the size of the gravitational force.
2) The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it.
3) There are the two components of the projectile's motion - horizontal and vertical motion.
4) The sun's gravity pulls the planet toward the sun, which changes the straight line of direction into a curve. This keeps the planet moving in an orbit around the sun. Because of the sun's gravitational pull, all the planets in our solar system orbit around it.
