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.

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.

i think its a plant or dog since both of them also have cells
Because it permits materials to enter and exit a cell, a cell membrane can be compared to a door. A door allows objects to pass through it as it opens and closes.
What is cell membrane made of?With a few rare exceptions, p - series, which are made up of glycerol, a nitrogen base, and two fatty chain, are the primary component of cellular membranes, both cytoplasmic membrane and interior membranes. Therefore, the cell membrane serves two purposes: first, as a barriers keeping the components of the cell inside and undesired materials out, and second, as a gate permitting the passage of vital nutrients through into cell as well as the flow of byproducts out of the cell.
What role does the cell membrane perform?Every cell has a phospholipid bilayer, also called a cell wall, that shields the inside of the body from the outside world. The cell barriers is a lipid bilayer that is porous. The cell regulates the flow of substances from and to the cell.

PLS HELP ASAP Select the word that means how easily water can move through a substance. Lesson 2.03 o particles permeability porosity
Answers
Answer:
permeability
Explanation:
dictionary definition: the state/quality of a material or membrane that causes it to allow liquids or gases to pass through it
in biology we use this term to describe the cell membrane, it is "semi-permeable" because it allows certain gasses and molecules to pass through
The water can easily move through a substance and it is called permeability. Hence, option B is correct.
What is permeability?The ability of molecules to pass through a biological membrane or barrier is known as biological permeability. Because cell membranes are selectively impermeable, substances cannot pass through the barrier without consideration. Some of the characteristics that affect permeability include polarity, hydrophobicity, charge, size, and shape.
The metabolic activities, survival, and potential use of the cell in both biotechnological applications and physiological systems are all greatly impacted by the cell membrane permeability, which controls the rate of solute transport into and out of the cell.
The water can easily move through a substance when the substance is permeable. Hence, option B is correct.

The levels of chlorine used for disinfection of drinking water causes long-term health effects because chlorine is toxic substance that greatly damaged cells and tissues of our body. Chlorine has low protection against protozoa due to its ineffectiveness on the protozoans organisms. These protozoa also adversely affected our health so we can say that chlorine has to be used in a limit which does not harm our body.

Sustainable forestry: seeks to conserve forests for the long-term commercial harvest of timber and non-timber forest products by maintaining a mix of forest trees, by age and species, rather than imposing a monoculture. due to the complexity of goals, is most effective when it involves cooperation among environmentalists, loggers, farmers, indigenous peoples, and local, state, and federal governments. approaches vary from one forest ecosystem to another, in response to different environmental, cultural, and economic conditions. is all of the above.
Answers
Answer:
Yes, it is all of the above.
Explanation:
Yes, all the above statements are necessary for sustainable forestry because trees and other wild plants of the forest are necessary for all farmers, loggers, environmentalists, indigenous peoples and for the governments. The environmentalists study on these plants to find out the impact of these different plants on the environment, the farmers cultivate trees and plants to get money by selling it, the employment of loggers also related to these forests and the indigenous peoples also gain benefits by gaining food as well as medicines from it. This forest also fulfill the needs of wood and other products of the country.

Dr. Flores wants to know which of the forum claims is best supported by the evidence you have gathered from your previous Sim observations and the text. Select the claim you think is best supported from the options below. Claim 1: Molecules in a substance disappear or no longer exist when a substance changes phase. O Claim 2: Molecules in a substance move differently when a substance changes phase. Claim 3: Molecules in a substance change into a new kind of molecule during a phase change.
Answers
Answer:
Claim 2: Molecules in a substance move differently when a substance changes phase.
Explanation:
Molecules in a liquid phase move freely and bump into each other. In a gas phase, the molecules move with a lot more energy and bump more times against each other; there is a lot of space for the molecules to move. In a solid phase, the molecules hardly move, there is not much space between them, and they are together, often in a regular pattern.
In conclusion, when matter changes from one phase to another, the molecules move differently.
Answer:
you will need to either add or take away energy and pay attention to how the molecules move. Molecules of a solid move in place, molecules of a liquid move around each other, and molecules of a gas move away from each other.

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.
Answers
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:
La sensación que experimento en la boca cuando tengo ganas de comer y estoy delante de un alimento que me gusta mucho es la de que "se me hace agua la boca".
Así, al percibir la presencia de un alimento, el cuerpo humano instintivamente comienza a generar saliva en una proporción mayor a la normal, con el objetivo de lubricar la boca y la garganta para facilitar la ingesta de alimentos. A esta situación se la conoce coloquialmente como "hacer agua la boca".
