The smoking or act of inhaling smoke can damage the respiratory system by reducing the surface area for the exchange of the gases and can lead to cancer as well.

Smoking can cause lung disease by damaging your airways and the small air sacs (alveoli) found in your lungs. It can also cause irritation of the trachea (windpipe) and larynx (voice box). Inhaled tobacco smoke moves from the mouth through the upper airway, ultimately reaching the alveoli.

As the smoke moves more deeply into the respiratory tract, it can cause inflammation and damage to the cilia, tiny hairs that play an essential role in the function of the respiratory system. Smoking can also increase the production of phlegm and mucus, leading to an increased risk of respiratory infections. It can also damage the cilia that help to clear unwanted particles from our lungs over time. Cigarette smoke can also contain high levels of carcinogens, which can lead to lung cancer.

Nuclei are labeled C in the diagram, as they are the larger structures and typically contain the genetic material (DNA) of the organism, while mitochondria are labeled D and are smaller organelles responsible for producing energy in the cell.

Organelle helps the cell maintain homeostasis are Cell membrane, Mitochondria, Autophagosomes, Lysosomes

The cell's outer layer, or cell membrane, acts as a largely permeable barrier to the extracellular environment. The cell membrane is a semi-permeable barrier that only permits certain chemicals to enter the cell.

Mitochondria are the powerhouse of the cell, but they also actively contribute to homeostasis. The cytoplasmic levels of nutrients are detected by mitochondria, which are also involved in the breakdown of lipids.

By destroying and eliminating hazardous substances including outdated or damaged organelles, pathogens, protein aggregates, and storing nutrients like lipid droplets, autophagosomes contribute to homeostasis. These dangerous chemicals are delivered to lysosomes by autophagosomes. The primary recyclers within a cell are lysosomes. They export their remains outside the cell after digesting the deadly chemicals.

Thousands of genes make up a single chromosome ,a double helix DNA molecule wrapped around proteins.

Chromosome is a structure found inside the nucleus of a cell . It is made up of proteins and DNA organized into genes. Each cell normally contains 23 pairs of chromosomes, of which 22 pairs of chromosomes are called the autosomes and the last pair of chromosomes is called the sex chromosome and are individually called the X and Y chromosome.

In most of the chromosomes, the very long thin DNA fibers are coated with packaging proteins, in eukaryotic cells the most important of these proteins are the histones.

Chromosomes allow the DNA to be accurately copied during these cell divisions.This ensures that our inner mechanisms proceed smoothly and efficiently.

In a global convection cell the correct option is (C). Cool air and warm air repeatedly collide, pushing air up and causing storms.

In a convection cell, the alterations are profound. The air molecules start to move and vibrate as the air at the cell's base heats. As a result, they start to spread out and collide, which reduces the density of the air parcel.

Convection is a pattern that occurs on a large scale. On a smaller scale, it also takes place within certain storms. However, because to Earth's rotation, the air that travels north and south from the equator likewise revolves with the Earth. Northbound air makes a right turn. Southbound air turns to the left.

Less dense air rises and moves away from the equator in a global convection cell. And the dense air from the pole flows backwards toward the equator as it descends. The poles can be thought of as the longitudinal edges of the earth's sphere, with the equator acting as its centee. The Coriolis Effect, a result of the spinning of the Earth, also aids in this airflow.

The examples of environmental influences

There is speculation that environmental factors can affect behavior both directly and indirectly. The indirect causal mechanism illustrates how cognitions that are specific to a behavior play a mediating role in the influence of the environment on behavior. A direct influence shows how the environment automatically and unconsciously affects behavior.

Certain behavioral and personal characteristics are hypothesized to modify the causal pathway (i.e., inducing either the automatic or the cognitively mediated environment – behavior relation). The EnRG framework also uses an energy balance approach, which encourages an integrated investigation of factors influencing nutrition and exercise.

Explanation:

Joining two Monosaccharides will create a Disaccharide. For example, the monosaccharides, glucose, and fructose bond together to form the disaccharide sucrose, which is produced by plants and is used in white sugar.

Mendel established a set of five guiding principles to explain how features are passed down in pea plants, which he called his "five-part hypothesis." The following rules are there are specific "factors" that are transferred from parent to offspring and defining traits.

For each attribute, each parent gives their offspring one component. One factor will be dominant and the other will be recessive when the factors influencing a trait are distinct.

The phenotype will show the expression of the dominant factor but not the recessive factor. A child has a 50% chance of getting a particular trait from a parent.

Mendel's five-part hypothesis has been expanded upon and refined in the century and a half since his initial experiments, but the basic principles he discovered continue to form the foundation of modern genetics. Mendel's work helped establish the concept of the gene as the unit of inheritance and the idea that different versions of a gene (alleles) can result in different traits.

In his law of segregation, he put forth the concept of paired components being separated during the creation of gametes. According to Mendelian law, every pair of unit components would separately assort into brand-new gametes.

Only one version of a trait will emerge in the offspring of two parents who have different, opposing characteristics, according to Mendel's law of dominance. The dominant trait will be the only phenotypic trait that the hybrid offspring exhibits. The dominance law is the fundamental rule of inheritance.

Because a gamete only contains one of the two alleles dominant or recessive and not both, the law of segregation is also known as the law of pure gametes.

The development of reproductive cells causes various genes to separately separate from one another, according to the Principle of Independent Assortment. During his research on the genetics of pea plants in 1865, Gregor Mendel made the first observation of an independent assortment of genes and their related phenotypes.

In order to survive on the ISS, bacteria must be able to withstand the immense gravitational forces, exposure to radiation, lack of oxygen, and other environmental factors that are not present on Earth.

Fortunately, bacteria have evolved a variety of adaptations that allow them to survive and thrive in space.One of the most important adaptations for bacteria living on the ISS is the ability to survive in low-oxygen environments. The ISS has very low levels of oxygen, which are not conducive to most life forms. However, many bacteria have adapted to survive and reproduce in these conditions.

Bacteria have developed specialized metabolic pathways that enable them to use different sources of energy, such as carbon dioxide, sulphur, and nitrogen compounds, that are more abundant in the environment of the ISS than oxygen. This allows them to survive and reproduce in the low-oxygen environment of the ISS.

Bacteria have also developed the ability to tolerate the intense radiation exposure that is present on the ISS. Radiation can cause DNA damage and mutations, which can be fatal for bacteria.
