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

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

Daughter cells formed by mitosis have exact copies of the parent cell's DNA. What process ensures that is possible?
Daughter cells formed by mitosis have exact copies of the parent cell's DNA. The anaphase process ensures that is possible.
What is mitosis?Cell division occurs during mitosis. All eukaryotic cells go through the process. There are four stages to the process. The cell divides during the procedure. A daughter cell that is identical to the parent cell is created.
Prophase: This is mitosis's initial phase. At this point, the chromosomes begin to compress and the cell begins to break.
This is the second phase, or metaphase. The chromosomes align in the spindle fiber during this stage, and a checkpoint is also established.
Anaphase: At this time, the sister chromatids separate, align, and the chromosomes divide.
The final phase is known as the telophase. The nuclear membrane developed as the nucleus closed.
Therefore, the process that ensures the daughter cells formed by mitosis have exact copies of the parent cell is the anaphase.

1. What two reactants enter the mitochondrion?
2. Compare the reactions in mitochondria with glycolysis.
1. How does a cell obtain energy?
2. Under what conditions does fermentation occur in a cell?
3. If a cell could perform both cellular respiration and fermentation, which process would benefit the cell more?
Answer:
1.NADPH2 and FADH2 , and O2
Explanation:
NADPH2 and FADH2 get oxidized in the electro transport chain into NADP+ and FAD+ and water and oxygen and yield 3 ATP molecules and 2 ATP molecules per each molecule respectively
Following are the answers:
The two reactants that enter the mitochondrion are pyruvate, the end product of glycolysis, and oxygen.In the mitochondria, pyruvate and oxygen undergo a series of reactions called cellular respiration, which produces energy in the form of ATP. This process is more efficient than glycolysis, which only produces a small amount of ATP.A cell obtains energy through a variety of processes, including cellular respiration and fermentation.Fermentation occurs in a cell when there is a lack of oxygen, such as in anaerobic conditions.In general, cellular respiration is more efficient than fermentation in producing ATP, but fermentation is a useful process for cells to produce ATP when oxygen is not available.What is mitochondria?Mitochondria are organelles found in the cells of most eukaryotic organisms, including plants, animals, and fungi. They are often referred to as the "powerhouses" of the cell because they are responsible for producing the majority of the cell's supply of adenosine triphosphate (ATP), which is used as a source of chemical energy.
Mitochondria are membrane-bound structures that contain their own genetic material, separate from the cell's nucleus, and are responsible for their own replication. They have unique characteristics that allow them to produce energy through the process of cellular respiration, a series of reactions that convert the energy from food molecules, such as glucose, into ATP. This process is one of the most important biological processes in living organisms, as it allows cells to perform their functions and sustain life.

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
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.

A. generation
B. population
C. individual
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.
