exchange of gases in the human breathing system takes place in the?

Answers

Answer

alveoli

Explanation

During gas exchange oxygen moves from the lungs to the bloodstream. ... This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

Required Answer :-

The exchange of gases takes place in the alveoli.

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Additional information :-

Alveoli are microscopic air sacs.

They are the primary sites of exchange of gases. Gas exchange also occurs in lungs and tissues by diffusion.

Atmospheric air contains little CO2, but blood flowing in pulmonary capillaries has a higher concentration of CO2.

CO2 diffuses from higher concentration in blood across walls of alveolar capillaries to lower concentration in air in alveoli.

Blood coming into pulmonary capillaries is oxygen poor and alveolar air is oxygen rich.

Oxygen diffuses from higher concentration in alveoli across walls of alveolar capillaries to lower concentration in blood.

The only system that does not pass through the thalamus on its way to the cerebral cortex is the __________ system. A. Tactile B. Gustatory C. Olfactory D. Visual.

Answers

The cerebral cortex process the information delivered by the thalamus, the information is related to the senses.

The only system that does not pass through the thalamus on its way to the cerebral cortex is the olfactory system.

The systems that pass through the thalamus are:

1. The visual sensation or information passes through the visual occipital cortex. It then delivers the information from the thalamus to the cerebral cortex.

2. The gustatory cortex is the region of the cerebral cortex, which is responsible for the senses of tastes and flavor. It also passes through the thalamus on its way to the cerebral cortex.

3. The tactile system includes the senses of touch. It is the information received through the receptors present on the skin. It also delivers the information to the cerebral cortex via the thalamus.

4. The olfaction system is not involved in the thalamus pathway. The olfactory cortex is present in the temporal lobe, which is not routed through the thalamus.

Thus, the correct answer is Option C.

A parallel universe by definition is; a separate universe or world that coexists with our known universe but is very different from it. a realm of existence and experience that is fundamentally different from the one that most humans share; a separate reality ultimately.

Water is transparent and lets sunlight pass through. Therefore, the correct option is C.

Water's transparency and ability to pass through sunlight is not just a product of its polarity. This is mainly because water absorbs only specific wavelengths of light, particularly those in the visible spectrum, while allowing other wavelengths to pass through. Rather than being a direct result of polarity, this property is related to the electrical structure of water molecules and their interactions with light. On the other hand, the interplay of water polarity and hydrogen bonding is the reason for the A, B and D properties, respectively.

Therefore, the correct option is C.

1. What percentage of the offspring will be heterozygous?
2. Why does each parent contribute only one allele to the offspring?

Answers

Answer:

1. 50%

2. Every gamete only contains 50% of the genetic information or half of the information for a gene.

Explanation: 1. Heterozygous means the pairs consist of a dominant and a recessive, or one big and one small letter, so only 2/4 or 50% are heterozygous.

2. Every sex cell has half of the chromosomes you need to make an embryo so you end up only having one allele as well

Heterogeneous means different

Here they are 2Total 4

Percentage:-.

2/4×100=50%

Read the text The Milky Way:The band that looks like milk in the night sky isn't actually milk, of courseit's a galaxy. A galaxy is a huge cluster of stars, dust, gas, and other objects bound together in space. Our Solar System, which includes the sun, Earth, and other planets, is part of the Milky Way galaxy. The Milky Way is about 14 billion years old. Almost 10 billion years older than our Solar System!It took many years to discover the Milky Way. In the early 1500s, Nicolaus Copernicus was the first to show that Earth was an object orbiting the Sun. In the early 1600s, Galileo Galilei used a basic telescope to show that the Milky Way was made up of countless stars. Then, in the late 1700s, William Herschel tried to map out the shape of the Milky Way. He did not realize that large portions of the galaxy were hidden by gas and dust, so he could not identify the true shape. Edwin Hubble had access to many powerful telescopes and tools to observe more objects in space. His work provided evidence that the Milky Way was only one of many galaxies in the universe. He also identified the spiral shape of our galaxy.Why was Herschel unable to correctly map out the shape of the Milky Way? He couldn't calculate the actual age of the Milky Way galaxy. He couldn't see through the Milky Way's gas and dust particles. He didn't know that the Earth and sun are part of the galaxy. He didn't know that the Milky Way was made up of many stars.marking as brainlest The _________ movements of the large intestine are slow compared to that of the small intestine.peristalticlymphdigestivesegmented why it is important to protect your children from stress and trauma?
