Which statement regarding lung cancer is correct?
A. Individuals with emphysema are not at risk for lung cancer.
B. Lung cancers are not aggressive.
C. More Americans die from lung cancer than any other form of cancer.
D. Only smokers will develop lung cancer.
Answer:
The correct answer is: C. More Americans die from lung cancer than any other form of cancer.
Explanation:
Lung cancer is one of the most aggressive cancers in the world, and is also the cancer that kills the most people in America every year (it is estimated that almost 140,000 Americans die from this cancer every year).
Emphysema is a chronic pulmonary disease that occurs when the air sacs in the lungs, called alveoli, enlarge and get damaged. This condition is mostly caused by smoking, and makes up a very significant risk factor for lung cancer.
Even when smoking makes up a huge risk factor for developing this and other types of cancer, non-smokers can develop lung cancer as well.
Answer: A is wrong, emphysema is not a risk factor for lung cancer. Lung cancer is primarily due to exposure to tobacco smoke and carcinogens in the smoke. Emphysema is due to loss of alveolar surface areas due to destruction of alveolar surfaces.The results is loss enough surface area for oxygen and C02 exchange in the lungs.
Generally D is wrong lung cancer is not limited to smokers only, smoking just increases it risk. Passive smokers can also develop cancer.But 45-50 of lung cancers is due to smoking. Beneze inhale from rubber industries,and asbestos industries are other places where Lung cancer can be developed after exposure.
A type of lung cancer can be agressive.(SCLC) While others can be slow.
C is correct.
Thus A is Odd

true or false: the momentum is moving planets does not depend on their masses
This is false, because plants have angular momentum, which is found by the formula (mass x velocity x distance). Therefore, mass is an important factor in a planet's momentum.
Why do birds have no urinary bladders?
which of the following words best matches this definition: The process in which the best adapted organisms survive and pass on their traits, while those that are NOT well adapted do not survive.
Answer:
Survival of the fittest
Explanation:
According to the Darwin’s theory of survival, a species can survive among its peers only when it is fit enough to adapt to the natural changes and hence remain alive till its reproductive stage in order to produce fertile offspring.
Such species which survive are known as fit species while the remaining unable to cope with changing environment die out at an early stage of life.
Question 9
What does it mean if the G2 checkpoint fails during cell Division
Answer:
If the checkpoint mechanisms detect problems with the DNA, the cell cycle is halted, and the cell attempts to either complete DNA replication or repair the damaged DNA.
Explanation:
The G2 DNA damage checkpoint is an important cell cycle checkpoint in eukaryotic organisms that ensures that cells don't initiate mitosis until damaged or incompletely replicated DNA is sufficiently repaired. Cells that have a defective G2 checkpoint enter mitosis before repairing their DNA, leading to apoptosis or death after cell division.
Which statement is correct about how lights travel
Answer:

Anaerobic respiration occurs when there is not enough oxygen to produce aerobic respiration.
This Pedigree represents a family with an Autosomal Recessive Disorder. What is the probability that IV4 and IV5 have a child with the trait?
As this family has an Autosomal Recessive Disorder, we must know that this disorder will only be expressed, in the family members who are homozygous recessive (aa), in this way, to know the probability of IV-4 and IV-5 to present the disorder, we must evaluate the probabilities of combinations of their parents' alleles in a diagram called a punnett square.
In the pedigree above, we can see that the dark colored balls and squares represent the members of the family who have the disorder and therefore have the "aa" genotype.
Thus, when observing the crossings throughout the family, we know that the father of IV-4, has the genotype "Aa", however we do not know which genotype of the mother of IV-4, but as she does not have the disorder, she may have the genotype "Aa", or "AA", for that reason, we must make the punnett square for both situations and see what the probabilities of IV-4 will present the disorder.
As you can see in the figure attached below, if IV-4's mother has the "Aa" genotype, IV-4 will have a 25% chance of presenting the disorder. If IV-4's mother has the "AA" genotype, IV-4 has a 0% chance of inheriting the disorder.
In the case of IV-5, we can see that his mother has the disorder and therefore has the genotype "aa", we know that his father does not have the disorder, but we do not know if the father's genotype is "AA" or "Aa "and therefore we must evaluate both situations.
As you can see in the figure below called "IV-5", if IV-5's father has the "AA" genotype, IV-5 will have a 0% chance of inheriting the disorder. However, if IV-5's father has the "aa" genotype, IV-5 will have a 50% chance of inheriting the disorder.
Which of the following two statements describe benefits of bio technology in medicine
1. using stem cells to treat disease
2. using antibiotics to treat infection
3. diagnosing genetic diseases
4. producing antibodies such as antitoxins
5. curing diseases such as smallpox
The correct answers are 1. Using stem cells to treat disease, and 3. Diagnosing genetic diseases.
Explanation
Biotechnology is a science that covers different areas such as chemistry, biology, and technology, to improve or facilitate procedures related to living organisms by manipulating living or parts of these in areas such as agriculture, medicine, and pharmacy. In the area of medicine, biotechnology is in charge of working with DNA to improve people's health. Also, it is in charge of investigating the cells to know in depth the problems that trigger diseases or genetic problems. Another use of biotechnology in medicine is through the use of stem cells in treatments for self-renewal or regeneration of damaged tissues. So, the correct answers are 1. Using stem cells to treat disease, and 3. Diagnosing genetic diseases.

How does an increased population size affect the amount of competition between organisms?
How do organims form carbon films
Answer:
Organisms form carbon film when sediments cover the organisms and decay of organisms form hollows.
Explanation:
Answer:
Organisms form carbon film when sediments cover the organisms and decay of organisms form hollows.
When an organism is covered by sediment, it begins to decay. When decaying, the organisms release a gas. This process in turns leaves a thin film of carbon that preserves parts of the organisms.

Cardiac muscle causes movement in the
Answer:
(look at explanation)
Explanation:
Cardiac muscle tissue works to keep your heart pumping through involuntary movements. This is one feature that differentiates it from skeletal muscle tissue, which you can control. It does this through specialized cells called pacemaker cells. These control the contractions of your heart.
Cardiac muscle causes movement in the heart.
What is Cardiac muscle?A cardiac muscle is the type of muscle found only in the heart. It is also called the myocardium.
The cardiac muscles are only located in the heart because they are made up of features that are specialized in pumping blood powerfully and efficiently. These features include:
they are involuntary and intrinsically controlled,they are striated,they are branched and single nucleated.Therefore, cardiac muscle causes movement in the heart.

Which of the following is the best definition of the term genotype?
A genotype is a feature in the genes. I know this since a pheno is a physical trait while geno meaning gene is a trait in the genes that can't be seen.
The genotype refers to an organism's entire genetic makeup, including all of its inherited genes.
What is a genotype?It represents the underlying genetic information that determines the traits and characteristics an organism will have, such as eye color, height, and susceptibility to certain diseases.
The genotype is influenced by the combination of genes passed down from parents and can also be affected by mutations or changes in the DNA sequence. The genotype serves as the blueprint for an organism's development and can impact its phenotype, or observable traits and characteristics.
