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.

Evolution is any change in the heritable traits within a
A. generation
B. population
C. individual

Answers

Answer:

B. population

Explanation:

CORRECT

Evolution is any change in the heritable traits within a population. Therefore, option (B) is correct.

What is evolution?

Evolution is the process by which populations of organisms change over time through the gradual accumulation of genetic variations. It is the central concept of modern biology and provides a framework for understanding the diversity of life on Earth.

Evolution occurs through the mechanisms of natural selection, genetic drift, gene flow, and mutation. Over time, genetic variations that confer a survival advantage in a particular environment become more common in a population, while those that are detrimental or neutral are selected against.

This process can lead to the emergence of new species, as well as the extinction of others. The study of evolution has practical applications in fields such as medicine, agriculture, and conservation, and helps us understand our place in the natural world.

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.

Explanation:

Answer: Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.

Sperm are produced in the glands sperm duct. testes. urinary bladder.

Answers

The testes. A pair of male reproductive glands called the testes can be found in the scrotum, which is a sac-like structure that is found on the exterior of the body.

Sperm and the male hormone testosterone are both produced in the testes, which are responsible for the function of the testes. When the sperm have been created, they pass via a number of ducts, such as the vas deferens, the epididymis, and the ejaculatory ducts, before being expelled from the male organ during the process of ejaculation. On the other hand, the urine bladder is a component of the urinary system, but it does not contribute in any way to the creation of sperm.
