a common sign of pneumothorax is a shift of the trachea towards the affected lung as air pressure sucks the lung away from the midline
Answers
The statement is false that in pneumothorax there is a shift of the trachea towards the affected lung as air pressure sucks the lung away from the midline.
Pneumothorax is the condition where the lung collapses. All the air present inside the lungs is pushed out. There occurs a tracheal shift to the opposite side during the lung collapse, but the lung is not moved away from the midline.
Lungs are the main respiratory organ of the body. They are involved in the exchange of air from the blood. The lungs comprise of several very small air sacs called alveoli. These alveoli increase the surface area of the lung and hence increase the ventilation.

a population of antelope normally graze on the abundant grasses in the savannah. however, a drought occurs and the amount of grass decreases. that year, many young, sick, and old antelope starve to death. a change in what variable lowered the antelope's population?
Answers
A change in carrying capacity lowered the antelope's population.
Carrying Capacity: An environment that can support the maximum population size of a species to sustain and grow its population is called carrying capacity. It is different for each species in a habitat because every species requires particular food, shelter, and social requirements. When a population approaches its carrying capacity, the rate of increase in a population usually slows and the birth rate equals the death rate.

Answers
In an epithelium, the apical membrane is also known as the Mucosal membrane.
What is apical membrane?In contrast to the basolateral membrane, the plasma membrane that makes up the lumenal surface of a polarized cell is known as the apical membrane. This applies to all polarized cells, including neurons and epithelial cells in particular.
The epithelial cells' tight connections at the apical surface stop proteins from migrating to the apical membrane. Thus, despite being different from the apical surface, the basal and lateral surfaces continue to be nearly equal to one another.

DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. The option (D) is correct.
What is DNA replication?
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.
Moreover, DNA must replicate (copy) itself so that each resulting cell after mitosis and cell division has the same DNA as the parent cell. All these cells, the parent cell and the two new daughter cells, are genetically identical.
Therefore, DNA replication is the process of creating two identical daughter strands of DNA. DNA replication occurs in the nucleus in eukaryotic cells and in the nucleoid region in prokaryotic cells. DNA replication occurs in S phase during the cell cycle prior to cell division.

What is Morgan hunt's experiment?
Morgan's arguments against the Mendelian and chromosomal theories were very different. Both hypothesized cellular structures or substances that somehow regulate developmental processes in an effort to explain biological occurrences. This reminded Morgan too much of the preformation theory, which held that the adult is already fully formed in the egg or sperm and dominated embryology in the late 18th and early 19th centuries.
Morgan contended in 1909 and 1910 that no single chromosome could contain particular hereditary qualities, despite the fact that he acknowledged that the chromosomes might have something to do with heredity. Additionally, he asserted that Mendelian theory was completely hypothetical because it was unable to define the actual processes of heredity, despite being able to explain and even forecast breeding outcomes.
For Morgan, the fact that each pair of chromosomes divides and that each chromosome thereafter enters a different sperm or egg cell in precisely the same way as Mendelian factors did not seem to be sufficient evidence to support the idea that the two processes are related.

Answers
I would have to go with option B. The amount of land and labor needed to produce food increased
Hope this helps
The amount of land and labor needed to produce food increased. Therefore, option (B) is correct.
The Industrial Revolution mechanised agriculture, increasing food production efficiency and reducing land and labour needs. The plough, seed drill, and motorised reaper enabled greater, more productive farming with fewer employees.
a, c, and d describe Industrial Revolution effects:
a. Fossil fuels powered manufacturing, transportation, and machinery during the Industrial Revolution.
c. Chemical companies created synthetic materials like plastics and synthetic fibres, which supplanted natural materials in numerous uses throughout the Industrial Revolution.
d. Machines supplanted human muscle and animal power: The Industrial Revolution's use of equipment in industrial processes displaced human and animal labour. This transformed industry and greatly enhanced production. Therefore, option (B) is correct.

H1N1 flu is a highly contagious viral infection caused by the influenza A (H1N1) virus. The symptoms of H1N1 flu are listed in the box below. An antiviral agent administered within 48 hours of the appearance of symptoms can reduce the severity of the illness. Screen Why is it important to administer an antiviral agent to an infected person within 48 hours of the appearance of symptoms? The H1N1 virus is transmitted through a vector host, such as a mosquito. The H1N1 virus is dormant in cells. The H1N1 virus does not mutate. The H1N1 virus replicates quickly.
Answers
Answer:
The H1N1 virus replicates quickly.
Explanation:
The H1N1 virus replicates quickly, which is why it is of high importance that an antiviral agent is administrated within the first 48 hours so that the reproduction rate of the virus can be lowered, resulting in an effective treatment against H1N1 flu. In other words, by administrating an antiviral in the first 48 hours, we are helping the body to fight the virus since the antiviral stops the reproduction of it, and we increase the chances of succeeding at it.

The trend shows that the Enzyme Pepsin is active and prefers the pH level of 2. While Trypsin Is much active at pH 8 and prefers that pH level.
Explanation:
You can tell by seeing the enzyme activity compared to the pH range. Enzymes are simply proteins which work around your body so pepsin since it is active in acidic levels (pH 2) is probably an enzyme found in the stomach.
The trend shows that the Enzyme Pep sin is active and prefers the pH level of 2. While Trypsin Is much active at pH 8 and prefers that pH level.
What are the functions of enzyme pepsin?Pepsin is an endo peptidase that breaks down proteins into smaller peptides. It is produced in the gastric cells of the stomach lining and is one of the main digestive enzymes in the digestive systems.
Pep sin is a stomach enzyme that serves to digest proteins found in ingested food. Gastric chief cells secrete pep sin as an in active zymogen called pepsinogen.
In the digestive tract pepsin effects only partial degradation of proteins into smaller units called peptides, which then either are absorbed from the intestine into the bloodstream.
