Why is some amount of air is left inside in your lungs after inhalation
Answers
Answer: Residual volume (RV) is the volume of air remaining in the lungs after maximum forceful expiration. In other words, it is the volume of air that cannot be expelled, thus causing the alveoli to remain open at all times. The residual volume remains unchanged regardless of the lung volume at which expiration was started. The residual volume (RV) is the amount of air that is left after expiratory reserve volume is exhaled. The lungs are never completely empty: There is always some air left in the lungs after a maximal exhalation.
So your answer will be Residual volume...
Hope this helps........ Stay safe and have a Merry Christmas!!!!!!!!! :D
It is left because exhaling will never remove all air from your lungs, if it did your body would shut down due to lack of oxygen to all organs. It distributed the atoms throughout the body.

B. How many offspring can an organism have?
C. Why do different organisms live in different places?
D. Are an offspring's traits similar to those of its parents?
Answers
Answer:
The correct answer is C. Why do organisms in different places have different traits?
Explanation:
Charles Darwin was a naturalist, biologist, and geologist from England and known for his theory of evolution. According to the theory, he observed different types of species of organisms such as birds, plants and fossils all over the world and found similarities in the characteristics.
He suggested that there were variations in species on the basis of specific geological locations. On the basis of these observations, he proposed that all species of organisms are come from the same ancestor but shows the differences due to the response to the condition of their habitat or location

The shadow zone exists due to the of seismic waves.
O A. reflection
O B. refraction
O C. absorption
OD. deletion
Answers
Answer:
B. refraction
Explanation: hope this helps!
The shadow zone exists due to the effect of seismic waves is the refraction. Thus, the correct option will be B.
What is Refraction?Refraction can be defined as the redirection of a wave as it passes from one medium to another medium. The redirection of the waves in a medium can be caused by the wave's change in speed or by a change in the medium of wave.
Seismic waves are the waves which follow the same law of refraction at the compositional boundaries. If the seismic wave velocity in the rock below a boundary is increasing then, the waves will be refracted in the upward direction and this speed up relative to their original path of movement.
Therefore, the correct option will be B.

Why are invasive species dangerous to the environment?
A)They pollute the environment.
B)They are always predators.
C)They threaten biodiversity.
D)They bring abiotic factors.
Answers
Answer:
C
Explanation:
They threaten the other animals. They can take their food, homes, and they don't have natural predators.
Invasive species are dangerous to the environment as they threaten the biodiversity. Thus, the correct option is C.
Invasive species are those imported species that are able to thrive rapidly in another foreign area by adapting and reproducing quickly.
Invasive species of plants and animals lead to an increase in the competition for survival, which results in decrease in the population of the native species.
The invasive species also affect the food web that is existing in the particular ecosystem, because of which other all organisms which are part of the food web are affected. They outcompete the native species for food,
Thus, biodiversity is threatened due to the invasive species.

Which part of the carbon cycle occurs when plants, trees, or fossil fuels are burned?
A. Transpiration B. Oxidation C. Photosynthesis D. Combustion
Answers
Answer:
Combustion.
Explanation:
It's just as it sounds, combustion is the process of burning something. In the carbon cycle, combustion occurs whenever any organic living or non-living thing is burned in the proximity of oxygen, afterwards producing carbon dioxide.
Combustion is the part of the carbon cycle which occurs when plants, trees, or fossil fuels are burned. Thus, the correct option is D.
What is Combustion?Combustion or burning is a high-temperature exothermic redox chemical reaction which occurs between a fuel and an oxidant. The oxidant is usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke. This is one of the major reasons of pollution.
Three main types of combustion include rapid combustion, spontaneous combustion, and explosive combustion.
Therefore, the correct option is D.

Answers
Answer:
d. It consists of alternating phosphates groups and deoxyribose molecules
Explanation:
The statement above best describes a portion of the molecule that is represented here.
Actually, the molecule represented here is the Deoxyribonucleic acid (DNA). The molecule is composed of two polynucleotide. The DNA carries genetic properties that lead to growth, development, reproduction and functioning of organisms. The phosphate group and deoxyribose molecule are found attached to the DNA. The phosphate group is also found in RNA and in ATP. The deoxyribose is known to be a five-carbon sugar molecule which helps to form the phosphate backbone of DNA molecules.
The given molecule is consists of alternating deoxyribose molecules and phosphates groups.

Answers
Answer:
(2) the placenta allows nutrients to diffuse from the mother to the embryo.
Explanation:
The placenta is a shared organ between the mother and the embryo. It diffuses the necessary nutrients from the mother to the future baby and the residues from this one to the mother, so that she can expel them. The placenta separates the mothers and the embryo blood, but it allows the diffusion of said nutrients and wastes through especial parts of the placenta with thin walls.
