The following four elements are essential for gas diffusion into the alveoli:

Pulmonary fibrosis is an illustration of a disease state that might develop when one of these important components is altered. Scarring causes the alveolar-capillary membrane to thicken in this disease, which affects gas exchange. Hence, individuals with pulmonary fibrosis may have breathing problems and shortness of breath, especially after exercise like climbing stairs.

Answer:

The correct answer is - natural selection.

Explanation:

The change of an allele's frequency or microevolution in a particular population due to its fitness benefit it provides to the individuals of the population can be caused by the natural selection process. Relative reproductive success is a measure of Fitness.

The change of an allele's frequency in deleterious traits mostly decreases in a population and this process is known as adaptive evolution. There is no or very small number of relative reproductive success present.

Answer:

(1) Calcium binds to troponin C, causing the conformational shift in tropomyosin that reveals myosin-binding sites on actin. (2) ATP then binds to myosin. (3) ATP is then hydrolyzed.

Explanation:

Calcium ions, troponin C and ATP play a crucial role in muscle contraction.

The sarcomere has to shorten in order for a muscle cell to contract. Sarcomeres' constituent thick and thin filaments, however, do not shorten. Instead, they go past one another, shortening the sarcomere while keeping the filaments at their original length.

The identified bands on the sarcomere were shown to differ at various levels of muscular contraction and relaxation, leading to the development of the sliding filament hypothesis of muscle contraction. The binding of myosin to actin, which results in cross-bridges that cause filament movement, is the process of contraction.

Some parts of a sarcomere shrink while others remain the same size. A sarcomere is defined as the space between two adjacent Z discs or Z lines; this space is shrunk as a muscle contract. Only thick filaments are present in the H zone, which is the center of the A zone, and it shortens during contraction.

Only tiny filaments may be seen in the I band, and it also shortens. Although the A band does not shorten during contraction—it stays the same length—it does become closer together before vanishing altogether.

Up until the Z discs get close to the thick filaments, thin filaments are drawn toward the center of the sarcomere by the thick filaments. As the thin filaments migrate inward, the zone of overlap—where thick and thin filaments share the same space—grows.

Therefore, calcium ions, troponin C and ATP play a crucial role in muscle contraction.

Answer:

Burning fossil fuels, releasing chemicals into the atmosphere, reducing the amount of forest cover, and the rapid expansion of farming, development, and industrial activities are releasing carbon dioxide into the atmosphere and changing the balance of the climate system.

What are the top 3 human activities that produce CO2?

Eighty-five percent of all human-produced carbon dioxide emissions come from the burning of fossil fuels like coal, natural gas and oil, including gasoline. The remainder results from the clearing of forests and other land use, as well as some industrial processes such as cement manufacturing.

What causes carbon dioxide to increase in the atmosphere?

Human Activity Is the Cause of Increased Greenhouse Gas Concentrations. Over the last century, burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This increase happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.

People receive their parents' chromosomes, which house their genes. The 23 pairs of the 46 chromosomes that make up the human genome total 46. Chromosomes are paired. One set of each pair of chromosomes—one from the mother and one from the father—is randomly inherited by a child from each parent.

Genes serve a variety of purposes.

As parts of genetic material, genes are also units of inheritance.

They regulate the phenotypes or morphologies of individuals.

Cell division requires the replication of genes.

Hereditary information is passed down from one generation to the next through genes.

Genetics: Interesting Facts

About 90% of the genetic material in mice and 98% in chimpanzees is shared by humans. A nearly complete copy of the human genome is found in every cell of the body. Both our mother and father contribute 23 chromosomes to us. Genes can be passed down to cause some diseases.

Answer:

Both processes require energy cuz respiration produces energy

Explanation:

The statement that is not true is that both processes occur in mitochondria as photosynthesis happens in chloroplasts. So the correct option is B.

While oxygen is needed for plant respiration, carbon dioxide is also released during the process. Plants, unlike people and other animals, don't have any specific structures for the exchange of gases, but they do have stomata (found in leaves) and lenticels (found in stems) that play a part in it. Compared to people and animals, leaves, stems, and plant roots respire slowly.

Respiration is distinct from breathing. Breathing is a phase in respiration that is completed by both humans and animals. Plants breathe differently through a process called cellular respiration, which they engage in throughout their whole existence since the plant cell needs the energy to survive.

Plants produce glucose molecules during this process of cellular respiration by using photosynthesis to absorb solar energy and transform it into glucose. Several real-world experiments show that plants can breathe. To provide their cells the energy they need to function and stay alive, all plants breathe.

Therefore the correct option is B.

The change results from the breakdown of starch into glucose by saliva is chemical change.

When bonds between molecules or atoms are created, disrupted, or both, chemical changes result.

In other words, a substance with one set of qualities gets changed into another substance with a different set of attributes.

Chemical decomposition is the term used to describe the subsequent chemical change as more products are produced as a result of this process.

When two materials interact to form a new substance, chemical synthesis—or, conversely, chemical breakdown into two or more independent molecules—occurs.

The starch gradually transforms into sugar when saliva is supplied because saliva contains the enzyme amylase, which helps break down starch.

Starch is a polysaccharide made up of many units of glucose. Amylase breaks down starch to produce a disaccharide called maltose.

Thus, the given one is the example of chemical change.

The two pieces of evidence that support the theory of the expanding universe are the red shift of light from distant stars and the existence of cosmic background radiation.

The correct answer is option B.

1. Red shift of light from distant stars: The observation of redshift in the light coming from distant galaxies provides evidence for the expansion of the universe. Redshift occurs when the light waves from an object moving away from an observer are stretched, causing a shift towards longer wavelengths. This phenomenon is consistent with the Doppler effect, where the wavelength of light appears to stretch as the source moves away. The redshift of light from distant stars indicates that galaxies are moving away from us and from each other, supporting the idea that the universe is expanding.

2. Existence of cosmic background radiation: The discovery of cosmic background radiation further supports the theory of the expanding universe. Cosmic background radiation is a faint, uniform microwave radiation that permeates the entire universe. It is believed to be residual radiation from the Big Bang, the initial event that is thought to have initiated the expansion of the universe. The presence of cosmic background radiation provides strong evidence for the hot, dense early stages of the universe and its subsequent expansion.

Answer:

the entire embryo

Explanation:

The trophectoderm refers to the polarized single cell layer that forms the wall of the blastocyst, thereby forming the first epithelium during embryogenesis. Moreover, the blastocyst is composed of 1-an inner cell mass (ICM) which will form all the tissues of the embryo's body, and 2-an outer layer composed of cells collectively called the trophoblast. The ICM of the blastocyst will form the embryoblast (which subsequently will give rise to the embryo itself) and the fetus, while the trophoblast will form all of the supporting tissues (i.e., amniotic sac, placenta, and umbilical cord). In humans, the blastocyst is the developmental stage of the embryo on day 5 after fertilization.

Answer:

40% is the percentage of the gamma allele in the population.

Explanation:

Available data:

What is the percentage of the gamma allele in the population?

According to Hardy-Weinberg, the allelic frequencies in a locus are represented as p and q, referring to the allelic dominant or recessive forms. The genotypic frequencies after one generation are p² (Homozygous dominant), 2pq (Heterozygous), q² (Homozygous recessive). Populations in H-W equilibrium will get the same allelic frequencies generation after generation. The sum of these allelic frequencies equals 1, this is p + q = 1.

In the same way, the sum of genotypic frequencies equals 1, this is

p² + 2pq + q² = 1

Being

If the percentage of delta allele in a population is 60%, this means that its frequency is 0.6. By clearing the equation p + q = 1, we can calculate the gamma allele frequency. This is:

p + q = 1

0.6 + q = 1

q = 1 - 0.6

q = 0.4

Then the percentage of gamma allele in the population is 40%.

We can also think about it like this:

If the sum of the allelic frequencies equals 1, then 1 is 100% of the allelic frequencies. And if the percentage of delta allele in a population is 60%, then 40% is the percentage of gamma allele.
