A newborn breathes four times as often as an adult, air sacs at the end of bronchioles are called alveoli, the epiglottis protects the larynx from ingested materials, and blood leaving the lungs is oxygenated.

The respiratory system of humans is a complex arrangement of structures that allows us to breathe in oxygen and expel carbon dioxide. The journey of air begins at the nasal cavity, passes through the pharynx, and progresses into the larynx. The trachea, or windpipe, is next in the path, followed by division into right and left primary bronchi that lead into each lung. These bronchi branch out into smaller bronchioles which then terminate in clusters of air sacs called alveoli, the site of gas exchange with the capillaries in the lungs. Inhalation causes the diaphragm to contract, enlarging the chest cavity and drawing in air, whereas exhalation is due to diaphragm relaxation, pushing air out of the lungs.

Answering the student's questions:

A newborn breathes about four times as often as an adult. This high respiratory rate is necessary to support their rapid metabolism and growth demands.

The cluster of air sacs at the end of each bronchiole is called the alveoli. These structures are vital for the exchange of oxygen and carbon dioxide between the lungs and the blood.

The flap of elastic cartilage that protects food from entering the larynx when swallowing is called the epiglottis.

When blood leaves the lungs, it is oxygenated, meaning that it has a high concentration of oxygen and a low concentration of carbon dioxide after gas exchange has occurred in the alveoli.

Answer:

The theories may get modified with time as new information or new technologies get discovered or get developed. New developments result in the modifications in the methods of experiments that offer information, which may or may not encourage the prevailing theory. If the theory is still supported, it may be updated, however, if it is not even if the results are relevant and true, the theory may get substituted.  

The answer is ''interactions between the hydrosphere and atmosphere during a storm''.

When organisms do not need a mate in reproduction, it is asexual

Asexual reproduction is a type of reproduction in which a single organism produces offspring that are genetically identical to the parent. This type of reproduction involves only one parent and there is no change in the number of chromosomes. Asexual reproduction occurs in unicellular organisms such as archaea and bacteria. Types of asexual reproduction include; budding, sporogenesis, binary fission, and vegetative propagation.

Answer:

The correct answer will be option radiolarians and foraminiferans.

Explanation:

The 6 kingdom classification system classifies the eukaryotes into six “supergroups”  including all kingdoms. These supergroups are monophyletic that is they have evolved from a common ancestor.

Amoebozoa is a supergroup consisting of 2,400 species of amoeboid protists which include organisms such as amoeba and entamoeba while radiolarians and foraminifera are the subtypes of another supergroup called Rhizaria which includes many amoebas.

Thus, radiolarians and foraminiferans are the correct options.

Phylum Amoebozoa includes amoebas, but does not include radiolarians or foraminiferans. These latter groups belong to the Rhizaria phylum instead.

The phylum Amoebozoa includes amoebas but does not include radiolarians or foraminiferans. Radiolarians and foraminiferans belong to the group Rhizaria, not Amoebozoa. The main characteristic of Amoebozoa is that they move using extensions of their cytoplasm called pseudopodia, whereas radiolarians and foraminiferans have their own unique characteristics.

Answer:

Over production

Explanation:

Frogs are very carefree parents and thus unlike other adult species of animals who take care of their young ones for making them enable to survive, frogs do not look after their young ones and this is the reason that out of three to four thousands eggs produced at a time by female only 4 to 5 eggs survive till adulthood.  

In order to make the cycle moving from one generation to other, frogs overproduce eggs so that at least a few of all survive till adult hood and reproduce further.

The right answer is  B.

Puberty is a stage of development that is reached when reproductive organs are functional. In humans, it refers to the transition from childhood to adulthood. It is particularly notable for its rapid growth due to growth hormones and the development of primary and secondary sexual characteristics due to sex hormones, with notable behavioral changes including an increased need for sleep due to a shift in melatonin release.

A chemotherapeutic drug is most useful when it interferes with rapidly dividing cells, as this is a characteristic of cancer cells. Chemotherapy can cause side effects due to this mechanism affecting healthy cells too, hence combination therapies are used.

For a chemotherapeutic drug to be useful for treating cancer cells, it is most desirable that it interferes with rapidly dividing cells (Option E). This is because cancer cells are characterized by their uncontrolled division. Chemotherapy drugs target these rapidly dividing cells to prevent their growth and spread. By interfering with key processes such as DNA duplication or mitotic spindle formation, these drugs can lead to the death of cancer cells. However, it is important to note that because these drugs also affect other rapidly dividing healthy cells in the body, they can cause side effects like hair loss and damage to the intestinal lining. Combination chemotherapy is often used to enhance therapeutic efficacy while trying to limit toxicity to healthy tissues.

Answer:

Cdc stands for cell division cycle and cdk is cyclin dependent kinase.

Explanation:

Cdc and cdks are involves the process of cell cycle. The cdk are the enzymes that attaches phosphate group to different molecules. The phosphorylation process allows the cell to move to next stage in the cell cycle.

The Cdc protein allows the removal of residues that are attached to inhibitory phosphate. This cdc protein control cell cycle progression. This allows the cell to move through cell cycle stages that includes S phase and mitosis.

Answer:

B

Explanation:

This step follows the Central Dogma of Molecular Biology, which describes the two-step process, transcription and translation, by which the information in genes are used to make proteins i.e. DNA → RNA → protein.

Deoxyribonuceic acid (DNA) is the stored form of genetic material in a cell. It contains all the genetic instructions needed for the optimal functioning of an organism. However, this information needs to be expressed. This process of expression is done by transcription and translation processes.

Transcription is the process of copying the information in the DNA molecule into a RNA molecule. It involves making a complementary strand of mRNA from a DNA template.

After the mRNA is synthesized, its nucleotide sequence is then used to synthesize proteins. This second process is called TRANSLATION. Translation occurs in the ribosome where building blocks (amino acids) are added in a chain-like manner based on the information on the mRNA to eventually lead to a polypeptide or protein.

Answer:

D. The cell's energy level will diminish as the enzyme decreases.

Explanation:

Cellular respiration in our body occurs so that our body could generate energy in the form of ATP primarily from carbohydrates. A series of reactions catalyzed by various enzymes facilitate cellular respiration. If our diet lacks the enzymes which are responsible for carrying out cellular respiration and there is no means to produce those enzymes effectively in our body then the cellular respiration reaction will become slow as less enzymes will be available to catalyze the reactions which lead to cellular respiration. Less enzyme means less conversion of substrates into products which leads to less production of ATP. If less ATP will be available then cell's energy level be low.

Migration describes seasonal movement of individuals into and out of a population. So, the correct options for 6, 7, 8 and 9 are D, D, B and A respectively.

A population is a collection of people belonging to the same species who coexist in the same location. A population's size is determined by how many people there are in it.

Different levels of population organisation, from a single person living in a small community to an entire species dispersed over the world, can be examined. The features of a population, such as its age, sex, or genetic make-up, can also be used to characterise it.

Migration is the name given to the seasonal influx and exodus of people from a population. Population increase can be expressed as (Immigration + births) - (Emigration + deaths). The "Logistics limit" of a specific environment refers to the greatest population size that it can support. A population is said to be growing exponentially if it grows by 5% annually.

Therefore, the correct options for 6, 7, 8 and 9 are D, D, B and A respectively.

The correct statement is that atoms tend to react to achieve 8 electrons in their outermost shell, adhering to the octet rule, and forming chemical bonds like ionic bonds through the attraction between oppositely charged ions.

Among the provided statements, the correct one is that atoms tend to react so that they acquire 8 electrons in their outermost shell. This is known as the octet rule, which describes the tendency of atoms to prefer to have eight electrons in the valence shell, as this configuration provides stability. Chemical bonds, such as ionic bonds, are indeed formed through the attraction between oppositely charged ions, where atoms can either lose or gain electrons to achieve a full octet.

The other options are false. Chemical bonds are not repulsive forces; they are attractive forces that serve to bind atoms together. Moreover, the most reactive atoms are typically those that do not have a full set of eight valence electrons, as they seek to gain, lose, or share electrons to achieve a full valence shell.

When you walk your dog, you are using energy from the sunlight to power this activity. This energy comes from plants that have converted sunlight into chemical energy through photosynthesis.

Explanation:

When you walk your dog, you are using energy from the sunlight to power this activity. This is because sunlight is converted into chemical energy by plants through a process called photosynthesis. The chemical energy is then transferred to animals when they eat plants or other animals that have eaten plants. When you walk your dog, you are using the energy that originated from the sunlight and passed through the food chain.
