Why do people who smokes cigarettes are prone to lung cancer?
The cigarrettes have over 4.700 chemical substances and most of them are harmful or even poisonous, damaging your airways and the alveoli. The chemicals can affect our health in many ways, as they can damage DNA and make it harder for the cells to repair damaged DNA. Cancer usually is associated to a DNA damage, causing the damaged cell to replicate uncontrollably, creating a tumour. Therefore, damages in DNA structure can lead to a cancerous tumour.
Answer:
Smoking can cause cancer and then block your body from fighting it: Poisons in cigarette smoke can weaken the body's immune system, making it harder to kill cancer cells. When this happens, cancer cells keep growing without being stopped. Poisons in tobacco smoke can damage or change a cell's DNA.

In what direction, clockwise or counterclockwise, do the major circulation patterns rotate in the northern and southern hemispheres? why does each hemisphere have a different pattern?
The Coriolis effect makes storms swirl clockwise in the southern hemisphere and counterclockwise in the northern hemisphere. Because earth rotates on its axis circulating air is deflected towards the right in the northern hemisphere and towards the left in the southern hemisphere this effect called Coriolis effect.
Hurriances spin counterclockwise because the Coriolis effect. The equator rotates faster than other area of earth's surface and moving in a straight line on north to south axis will curve.
In southern hemisphere currents are deflected to the left. Storm system seem to rotate clockwise. This force is caused by the earth rotation and responsible for air being.

B) Uncontrollable worry about an accident
C) The impulse to hurt a family member
D) Constant and repetitive checking that the alarm is set
An example of a compulsion is D) Constant and repetitive checking that the alarm is set.
Compulsions are repetitive behaviors or mental acts that individuals with certain mental health conditions, such as obsessive-compulsive disorder (OCD), feel driven to perform. These compulsions are often performed in response to obsessive thoughts or to alleviate anxiety or distress. Compulsions are typically not connected to the actual event or situation they are intended to address, but rather serve as a way to temporarily relieve anxiety or prevent perceived harm.
In the given example, constant and repetitive checking that the alarm is set is a classic example of a compulsion. The individual feels compelled to repeatedly check the alarm to ensure it is set, even though they may have already checked it multiple times before. This behavior is driven by an irrational fear or anxiety that something negative will happen if the alarm is not set correctly. The act of checking the alarm becomes a repetitive behavior intended to alleviate the anxiety associated with the fear.
It is important to note that anxiety about contracting HIV infection from a sneeze (A) and uncontrollable worry about an accident (B) are examples of obsessive thoughts or worries, which are often experienced in conjunction with compulsions in OCD. However, in the given options, they do not specifically represent compulsions.

Earth has undergone some catastrophic changes, resulting in
periods of mass extinctions; How is it that life on Earth continued
following these catastrophes?
Even though there have been mass extinctions on the earth, life has still continued due to the survival of some plants and animals species in small isolated regions referred to as refugia.
The planet Earth has witnessed five mass extinctions which had decreased the biodiversity greatly, but then it had begun to climb again.
Although mass extinctions wipe out many species from the earth's surface. it is said that in actual only 5% of species get extinct, while other species get extinct due to natural selection and other such evolutionary processes.
New niches are created following mass extinction which gives rise to new species which have adapted to survive in the new ecosystems.

Statistics about Diabetes Type 1 and 2 (World Wide) : 2021
In 2021, the worldwide statistics for diabetes type 1 and type 2 indicated a significant global health concern with a high prevalence and increasing incidence.
Diabetes is a widespread health condition affecting millions of people worldwide. In 2021, the International Diabetes Federation (IDF) estimated that approximately 463 million adults between the ages of 20 and 79 were living with diabetes. This number is expected to rise to 700 million by 2045, highlighting the increasing global burden of the disease.
Type 1 diabetes, which is typically diagnosed in childhood or adolescence, accounts for approximately 5-10% of all diabetes cases. It is characterized by the body's inability to produce insulin, requiring lifelong insulin therapy. On the other hand, type 2 diabetes is the most common form, comprising around 90-95% of adult diabetes cases. It is often associated with lifestyle factors such as obesity, poor diet, and physical inactivity. The increasing prevalence of type 2 diabetes is closely linked to the global rise in obesity rates and sedentary lifestyles.
The impact of diabetes is not limited to the physical health of individuals but also extends to economic and social aspects. Diabetes is a leading cause of death and can lead to various complications, including cardiovascular disease, kidney damage, blindness, and nerve damage. It places a significant burden on healthcare systems, individuals, families, and societies as a whole. Promoting awareness, early detection, prevention, and effective management of diabetes are essential to address this global health challenge and improve the well-being of affected individuals.

Explanation:
a explanation for phenylketonuria
Phenylalanine hydroxylase (PHA) performs an enzymatic function during the conversion of phenylalanine, to tyrosine. Existing naturally in several types of foods, for instance, breast milk, PKU is an essential α-amino acid and one of the plethora of amino acids used in the formation of proteins. Phenylalanine exists in three forms; L-phenylalanine, D-phenylalanine (mirror image of L-phenylalanine), and DL-phenylalanine which is a typic combination of D and L-phenylalanine, and unlike D and L- phenylalanine, is not found in foods. On the other hand, tyrosine, apart from being a derivative of phenylalanine, is a non-essential amino acid that forms part of the list of amino acids utile during the constitution of proteins. Ordinarily, lack of PAH leads to the accumulation of phenylalanine (the phenylalanine is not converted to tyrosine) leading to the development of a disease called Phenylketonuria (PKU).

explain why microbiologists study protozoa, algae, and parasitic worms.
Microbiologists study protozoa, algae, and parasitic worms because they are crucial to the ecosystem. Protozoa are single-celled microorganisms found in soil, freshwater, and marine environments. They have a crucial role in maintaining the ecosystem by decomposing organic matter and controlling bacterial populations.
Algae, on the other hand, are primary producers and are responsible for producing a significant portion of the earth's oxygen. Microbiologists study algae to understand how they contribute to the ecosystem and how they can be utilized for biotechnology applications.
Parasitic worms, also known as helminths, are important to microbiologists because they cause serious diseases in humans and animals. Microbiologists study helminths to understand their life cycles, the mechanisms they use to infect their hosts, and how to develop effective treatments and preventions for the diseases they cause. For example, parasitic worms cause neglected tropical diseases (NTDs) that affect over one billion people globally, mainly in low-income countries.
Microbiologists studying these organisms can provide critical insights that help to control the spread of these diseases in affected communities.In conclusion, microbiologists study protozoa, algae, and parasitic worms to understand their role in the ecosystem and how they can be utilized for biotechnology applications. They also study parasitic worms to understand their life cycles and mechanisms of infection to develop effective treatments and preventions for the diseases they cause.
