a sailboat moves faster as the wind blows on its sail. this is an example of acceleration, force, speed, velocity

Answers

Answer:

force

Explanation:

Gravity and buoyancy are the two key forces that operate on a stationary sailboat. The power of the wind pulls on the sail in order for the boat to move which allows the boat to move. The powers are now unbalanced, which is apparent from the acceleration of the ships.

The boat accelerates until the forward portion of the force from the sails is matched by the drag from the water.

The copper wire is cut into three pieces of unequal lengths. All three pieces of copper would have (1 point)

A the same mass
B the seſme physical properties
C different crystal structures
D different arrangement of atoms

Answers

B.) The same physical properties.

Also the copper wire would also have the same Chemical Properties. They wouldn't have a different arrangements of atoms because that would mean they are a different substance. They wouldn't have the same mass whereas they are now in 2 pieces. Copper is not a crystal meaning it would not have any crystal structures. That leaves the only applicable answer to be B. Also in case you need to find whether or not two identical substances are the same would be by testing the melting point, hardness and solubility. I just finished working on this section in my own 8th grade Science class so I think this should either help you now or later on.

Which three organs are part of the digestive tract?

A) salivary glands, gall bladder, appendix

B)teeth, tongue, mouth

C)esophagus, stomach, small intestine

D)esophagus, liver, pancreas

Answers

Answer:

C

Explanation:

Due to the stomach and small intestine being part of the digestive tract and the esophagus allowing food, liquids and air to enter the torso

Esophagus, stomach, small intestine are part of the digestive tract. Therefore option C is correct.

The digestive tract, also known as the gastrointestinal tract, is responsible for the process of digestion in the human body. It consists of a series of organs that work together to break down food and absorb nutrients.

The three organs that are part of the digestive tract are the esophagus, stomach, and small intestine.

The esophagus is a muscular tube that connects the mouth to the stomach and helps in the transportation of food. The stomach is a sac-like organ that mixes and churns food with digestive enzymes and acids.

The small intestine is a long tube where the majority of digestion and absorption of nutrients occurs.

Therefore option C esophagus, stomach, small intestine is correct.

Which of the following is required for a trait to become more common
over time in a population? *
There must be many varieties of the trait in the population.
The trait must allow members of the population to eat only some kinds of foods.
The trait must be the result of an immediate change in the environment.
The trait must give individuals an advantage in producing offspring that survive.

Answers

Answer:Natural selection is a process that causes heritable traits that are helpful for survival and reproduction to become more common, and harmful traits to become more rare. This occurs because organisms with advantageous traits pass on more copies of these heritable traits to the next generation.

Explanation:

Answer:

B. 1/2

Explanation:

The genotypes of the parents are Ss and Ss. We know this because Heterozygous basically means different alleles. The punnet square of this problem will show that the possible genes given to the offspring are SS (capital letters mean dominant. keep in mind that sickle-cell anemia is a recessive trait, meaning it is written in lowercase), Ss, Ss, or ss. So this means the offspring will have a 1/2 chance of becoming heterozygous (Ss).
