Alveolar Surface Tension is Reduced by Pulmonary Surfactant. A lipoprotein substance known as surfactant is secreted by type II alveolar cells.

While breathing in and out, oxygen and nutrients are exchanged between the blood and alveoli in the lungs. When oxygen is inhaled from the air, it gets to the body's tissues via the alveoli, blood, and structures inside the body.

An alveolus is made up of an extracellular matrix encircled by capillaries, a layer of simple columnar mucosa (very thin, flattened cells), and also an epithelial layer. The alveolar membrane, sometimes known as the oxygen diffuses, which permits the exchange of gases, includes the epithelial lining.

The correct statement is "Speeds movement of food through the digestive system." The correct answer is B.

Physical activity can reduce the risk of colon cancer by speeding up the movement of food through the digestive system.

This means that harmful substances have less contact time with the lining of the colon and rectum, reducing the risk of cancer.

Exercise also helps to maintain a healthy weight, which is another factor in reducing the risk of colon cancer.

While lowering hormone levels and body fat levels may also have some impact on reducing the risk of colon cancer, these factors are not as directly related to the movement of food through the digestive system as physical activity is.

Additionally, there is some evidence to suggest that exercise can boost the immune system, but this is not considered to be the primary way in which it reduces the risk of colon cancer. Therefore, the correct answer is B.

If over a period of 1,000 years, a lake becomes a maple forest, then this process is secondary succession because it involves a slow mechanism of replacement between species.

The process of primary succession makes reference to the immediate species replacement as occurs after natural disasters, while secondary succession is a relatively slow mechanism in which species are replaced each other.

Therefore, with this data, we can see that primary succession and secondary succession are different in the sense they have distinct times to carry our species replacement.

Answer:

Burning fossil fuels, cutting down forests and farming livestock are the main factors of global warming

Explanation:

for further explanation

2011-2020 was the warmest decade recorded, with global average temperature reaching 1.1°C above pre-industrial levels in 2019. Human-induced global warming is presently increasing at a rate of 0.2°C per decade.

An increase of 2°C compared to the temperature in pre-industrial times is associated with serious negative impacts on to the natural environment and human health and wellbeing, including a much higher risk that dangerous and possibly catastrophic changes in the global environment will occur.

For this reason, the international community has recognised the need to keep warming well below 2°C and pursue efforts to limit it to 1.5°C.

Greenhouse gases

causes_greenhouse_gases

The main driver of climate change is the greenhouse effect. Some gases in the Earth's atmosphere act a bit like the glass in a greenhouse, trapping the sun's heat and stopping it from leaking back into space and causing global warming.

Many of these greenhouse gases occur naturally, but human activities are increasing the concentrations of some of them in the atmosphere, in particular:

carbon dioxide (CO2)

methane

nitrous oxide

fluorinated gases

CO2 produced by human activities is the largest contributor to global warming. By 2020, its concentration in the atmosphere had risen to 48% above its pre-industrial level (before 1750).

Other greenhouse gases are emitted by human activities in smaller quantities. Methane is a more powerful greenhouse gas than CO2, but has a shorter atmospheric lifetime. Nitrous oxide, like CO2, is a long-lived greenhouse gas that accumulates in the atmosphere over decades to centuries. Non-greenhouse gas pollutants, including aerosols like soot, have different warming and cooling effects and are also associated with other issues such as poor air quality.

Natural causes, such as changes in solar radiation or volcanic activity are estimated to have contributed less than plus or minus 0.1°C to total warming between 1890 and 2010.

Answer:D

Explanation:

Evolution

Individuals pass on adaptations to their offspring, due to natural selection. The correct option is D.

The English naturalist Charles Darwin and others developed the Darwinism theory of biological evolution, which contends that all species of organisms arise and develop through the natural selection of minute, inherited variations that improve the individual's capacity for competition, survival, and reproduction.

Darwin claimed that all species share a common origin, that species can change through time, and that new species develop from existing ones.

Charles Darwin, a naturalist of the 19th century, investigated the theory of natural selection.

Natural selection provides an explanation for how a species' genetic features might evolve through time. This could result in speciation, or the creation of a new, separate species.

Thus, the correct option is D.

Given data: Adult dosage of a substance is 280mg. Rule for calculating dosage for children between 1 to 12 years of age is given by the function, D(t) = a * t / t + 12. To find the rate of change of this function with respect to the child's age, we need to differentiate the function with respect to t.

Let's differentiate this function with respect to t. d/dt [ D(t) ]= d/dt [ a * t / t + 12 ]

Using quotient rule,= [ a * (t + 12) - a * t ] / ( t + 12 )²= a / ( t + 12 )²

Thus, the rate of change of child's dosage with respect to child's age is given by D'(t) = a / ( t + 12 )².

Hence, the required expression is D'(t) = 280 / ( t + 12 )².

Now, substituting t = 3,

we get, D'(3) = 280 / (3 + 12)²

= 280 / 225

= 1.244 mg/year

Substituting t = 12,

we get, D'(12) = 280 / (12 + 12)²

= 280 / 576

= 0.486 mg/year

Therefore, the rate of change of a child's dosage with respect to his or her age for a 3-yr-old child is 1.244 mg/year and for a 12-yr-old child is 0.486 mg/year. We are given the formula, D(t) = a * t / t + 12, which represents the dosage for a child as a function of their age, t. To find the rate of change of this function with respect to the child's age, we need to differentiate the function with respect to t.

Answer:

Stabilizing Variation.

Explanation:

This is the type of variation that occurs when genetic diversity decreases as the population of organism in a particular population based on a specific trait.

Organisms with varied or specific  traits within the population are selected against by the selection pressure,  with little chances of reproduction, while organisms in between, ( with least variation of  this particular traits) which are within the narrow range, survive to reproduce.Thus, this gives  rise to narrow population  of these  particular organisms,(stabilizing variation) which are therefore naturally selected.

Therefore, the variation of the organisms in this population is kept  close to the  centre of  the same  mean value.

Mitochondria convert the chemical energy of organic molecules to chemical energy in the form of ATP.

Mitochondria differ from chloroplasts in that mitochondria are the energy bank for each cell, whereas chloroplasts house chlorophyll, which provides green pigmentation for photosynthesis in plants.

Cellular respiration is a component of the metabolic process that breaks down glucose sugar molecules to produce energy in the form of ATP. The Krebs cycle, oxidative phosphorylation, and glycolysis are all components of cellular respiration. Cellular respiratory activity takes place in the mitochondria of the cell, where an oxygen-rich environment breaks down the sugar-like glucose into energy molecules. It also emits water and carbon dioxide as waste and by-products. So go for option A. It is in the mitochondria of cells that the process of cellular respiration takes place. This process takes place in mitochondria. As a result, photosynthetic reactants are by-products of cellular respiration, the link between cellular respiration and photosynthesis.
