Explanation:

The lungs are essential organs responsible for respiration, the process of exchanging gases between the body and the environment. Their primary function is to inhale oxygen from the air and exhale carbon dioxide, which is a waste product of metabolism.

The lungs are composed of a network of small air sacs called alveoli that are surrounded by blood vessels. When air is inhaled through the nose or mouth, it travels through the trachea, or windpipe, and into the lungs. The air then enters the bronchial tubes, which branch out into smaller and smaller tubes until they reach the alveoli.

In the alveoli, oxygen from the air diffuses into the bloodstream and is carried to the body's cells, where it is used to produce energy. At the same time, carbon dioxide from the cells diffuses into the blood and is transported back to the lungs, where it is exhaled out of the body during exhalation.

The lungs also play a vital role in regulating the body's acid-base balance by controlling the level of carbon dioxide in the blood. When carbon dioxide levels in the blood rise, the lungs increase the rate and depth of breathing to remove excess carbon dioxide from the body.

Overall, the lungs play a crucial role in the body's respiratory system, which is essential for maintaining the body's overall health and well-being.

Hemoglobin is 50% saturated at lower partial pressures in winter.

P50 is a measure of the partial pressure of oxygen at which hemoglobin is 50% saturated with oxygen. It is affected by a variety of factors, including temperature, pH, and the concentration of other gases such as carbon dioxide.

One reason why P50 might be higher in the summer than in the winter is because of differences in temperature. Hemoglobin is sensitive to temperature, and its oxygen-binding affinity decreases as temperature increases. This means that hemoglobin is less able to bind oxygen at higher temperatures, which results in a higher P50.

Explanation:

only the individuals with certain genetic markers and therefore abilities to survive a given threat, can reproduce. which has a changing effect for the species within only very few generations. which is on the timescale of evolution a sudden change.

but it depends on the nature of the threat.

if the threat itself develops slowly, then natural selection will also cause a slow change.

if the threat appears suddenly in full force, so will the change by natural selection.

immunization by vaccination turns the threat into slow mode, as it continues to being a threat by mutations.

A trait must have heritable variation in order for natural selection to occur, and the ownership of the trait must be associated with differential survival and reproduction.

Origin of giraffes' long necks is a classic example of natural selection at action. Animals resembling deer or antelope with necks of average length were the progenitors of current giraffes.

Natural selection happens when people with a certain genotype have a higher chance of surviving and reproducing than those with a different genotype, and as a result, are more likely to pass on their alleles to the following generation.

Nonsense mutations are point mutations that cause an mRNA codon to turn into a stop codon. If the mutation is at the beginning of the gene, it is more damaging because most of the protein is affected. The new molecule is shorter, quite different from the original one, and would not accomplish all its functions.  

When a change occurs in a single base pair, it is known as a point mutation. Points mutations might be either silent, missense, or nonsense.

Nonsense mutations turn the mRNA codon into a stop codon, making the mutated protein reach its end before the original protein.

The length of the new molecule depends on where the mutation occurred.

If the mutation occurs at the beginning it is more damaging than if it occurs at the end.

During a nerve impulse, neuron undergoes changes in ion movement across its cell membrane.

Sudden reversal of the electrical charge across membrane of resting neuron is called nerve impulse.

Initially,  neuron has a resting membrane potential of approximately -70 millivolts (mV) with more negatively charged ions inside the neuron compared to outside. When stimulus is received, ion channels open in response, allowing for influx of positively charged sodium ions into neuron. This influx of Na+ ions depolarizes membrane potential, causing  internal net charge to become more positive.

Once the membrane potential reaches certain threshold , voltage-gated ion channels open, causing larger influx of Na+ ions into neuron. This creates an action potential, rapid and transient change in membrane potential where internal net charge becomes more positive and external net charge becomes more negative.

As action potential moves down the axon of neuron, voltage-gated ion channels continue to open and close, causing wave of depolarization followed by repolarization. During repolarization phase, voltage-gated ion channels for K+ open, allowing efflux of K+ ions out of the neuron.

Answer:

C. each daughter cell receives a nearly perfect copy of the parent cell's genetic information.

Explanation:

During mitosis, the genetic material (DNA) is replicated and then divided equally between the two daughter cells, ensuring that each cell receives an identical set of chromosomes. Cytokinesis then physically separates the two cells. While some random mutations can occur during DNA replication, the overall amount and content of genetic information in each daughter cell is almost identical to the parent cell. Option A is incorrect because it suggests that the genetic information is altered, which is not necessarily true. Option B is incorrect because it suggests that the division of genetic material is random, which is not the case during mitosis. Option D and E are also incorrect.

Answer:

D. None of these are true

Explanation:

Mitosis and subsequent cytokinesis yields 2 daughter cells with identical genetic information to each other and the parent cell.

In the project, we must mention that global temperature change is one of the most pressing environmental issues facing the world today. It is the result of human activities and has numerous impacts on the planet and its inhabitants.

Global temperature change refers to the long-term increase or decrease in the average temperature of the Earth's atmosphere and oceans. Since the Industrial Revolution in the mid-19th century, the Earth's average surface temperature has increased by approximately 1°C, primarily due to human activities such as the burning of fossil fuels and deforestation, which have led to an increase in greenhouse gases in the atmosphere.

This increase in temperature has led to numerous impacts, including sea-level rise, more frequent and intense heatwaves, changes in precipitation patterns, and more frequent and intense extreme weather events such as hurricanes and floods. These impacts have significant consequences for human health, agriculture, biodiversity, and the economy.

In conclusion, it is essential that we take action to reduce greenhouse gas emissions and mitigate the impacts of climate change to ensure a sustainable future for ourselves and future generations.
