Answer: The body makes sure that food does not get into the lungs because the epiglottis closes the air pathway so that food will not enter it.
Answer:
food getting to the lungs will be aspiration
Explanation:
A flap of tissue called the epiglottis sits over the top of the trachea. This flap blocks food and drink from going down into the trachea when you swallow hence preventing food from getting into the lungs

In order to start a chemical reaction, energy is needed
Answer:
Option B
The activation energy must be reached.
Explanation:
According to the collision theory, the following criteria must be met in order for a chemical reaction to occur: Molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break. Molecules must collide with the proper orientation.

what are the harmful effects of bacteria.
Answer:
Some types of bacteria can cause diseases in humans, such as cholera, diptheria, dysentery, bubonic plague, pneumonia, tuberculosis (TB), typhoid, and many more. If the human body is exposed to bacteria that the body does not recognize as helpful, the immune system will attack them.

Some types of bacteria can cause diseases in humans, such as cholera, diptheria, dysentery, bubonic plague, pneumonia, tuberculosis (TB), typhoid, and many more.
If the human body is exposed to bacteria that the body does not recognize as helpful, the immune system will attack them. This reaction can lead to the symptoms of swelling and inflammation that we see, for example, in an infected wound.

Answer:
a. The hog farmer does not notice the barn smell from the working boots when he wears them on the porch of the house.
Explanation:
The hog farmer does not notice the barn smell from the working boots when he wears them on the porch of the house is the example of sensory adaptations. Sensory adaptation is a decrease in sensitivity to a stimulus after regular exposure to it. So the farmer can't smell his own boots due to regular exposure to the smell so we can say that it is an example of sensory adaptations..

Factors that could affect the current oxygen and carbon dioxide levels?
Explanation:
There are many factors, both natural and man-made, that affect the levels of carbon dioxide and oxygen in the atmosphere. Some of them are:
Burning of fossil fuels increases the level of carbon dioxide.
Cleaning agricultural land increases the level of carbon dioxide.
The availability of nutrients in plants affects the synthesis of oxygen.
The intensity of the sunlight can increase or decrease the synthesis of oxygen.
Deforestation and industrial expansion greatly affect carbon dioxide and oxygen levels.
The increase in consumer products due to population explosion and advances in health care can also fluctuate carbon dioxide and oxygen levels.
An increase in oxygen levels is thought to promote healthy living in the environment, whereas a decrease in oxygen levels can lead to a decrease in atmospheric layers (thinning of the ozone layer). This reduction allows more sunlight to reach the Earth's surface. Sunlight gets trapped inside the Earth and raises the temperature of the planet. It is also known as global warming.
A reduction in carbon dioxide to a certain level is good for the environment, but lower than normal levels can affect oxygen synthesis as plants absorb carbon dioxide and use it to synthesize oxygen during photosynthesis. Since carbon dioxide is a greenhouse gas, an increase in its level will cause global warming.

Answer:
enzymes are biological catalysts.
Enzymes are catalysts. Therefore, option (4) is the correct option.
Enzymes are biological catalysts made primarily of proteins that accelerate chemical reactions within living organisms. As catalysts, enzymes lower the activation energy required for a reaction to occur, thus speeding up the rate of the reaction without being consumed or permanently changed themselves. Enzymes achieve this by binding to specific reactant molecules, forming enzyme-substrate complexes, which stabilize the transition state and facilitate the breaking and formation of chemical bonds during the reaction.
Once the reaction is complete, the products are released from the enzyme, and the enzyme remains unchanged, ready to catalyze further reactions. Enzymes play a crucial role in metabolism, cellular signaling, and many other physiological processes, enabling life to function effectively. Therefore, option (4) is the correct option.

Answer:
The answer is "they undergo capacitation"
Explanation:
Sperm migrate through uterine contractions and the energies of its flagella to the uterine tube. In sperm motility, reverse peristalsis is engaged in the uterus and uterine tubes. For a sperm cell to fertilize an egg, it takes approximately 24 hours. The surface of the egg changes as the sperm penetrates the egg, therefore no sperm is allowed within. The kid is fully genetic, including whether it's a boy or a girl at the time of fertilization. Until they are trained it is difficult for sperm to be working.

Draw a Punnett Square to show Queen Victoria and her husband Albert. Queen Victoria’s genotype will be XX^H and Albert will be XY. X^H indicates the female sex chromosome carrying the gene for hemophilia.
Explanation:
XY XX^H
XX^H XX^H XY XX^H XX^H
XY XY XY XY XX^H
all the royal families in Europe were related
that must mean 1 family ruled all of europe
The family pedigree of Queen Victoria shows a number of hemophilic descendants. Because hemophilia is recessive disorder and Queen Victoria was a carrier. X-linked recessive disease most often occurs in males because Males have only one X chromosome.
XY XX^H
XX^H XX^H XY XX^H XX^H
XY XY XY XY XX^H
Which chromosome will cause the disease?
A single recessive gene on that X chromosome will cause the disease. Females have two X chromosomes so they can act as carriers for the disease.
What is hemophilia?
Hemophilia is a bleeding disorder that slows the blood clotting process.Hemophilia is x-linked recessive disorder
So, Queen Victoria was a carrier.
