The correct answer is :

9. higher

10. lower

Explanation:

The movement of Oxygen from alveoli to the blood capillaries is possible due to simple diffusion through the paper-thin membrane between them due to the concentration gradient. The Concentration of oxygen in the alveoli is higher than the blood capillaries so the movement of oxygen takes place.

The CO2 concentration in the blood is higher than in the alveoli, so it diffuses through the membrane from high concentration to low concentration to the alveoli.

Higher pressure  gradient in the alveoli to lower in the blood for oxygen transport.

Higher pressure gradient in the blood to the lower in the alveoli for C02 transport out of the cells.

Basically, the partially pressure of oxygen in the alveoli of  lungs during external respiration is 104mmHg.Whereas in the blood this is 40mmHg. This pressure gradients forces 02 through the 1 cell layer thick into the blood.

The reverse is the case in the blood for C02 with higher partial pressure of45mmHg in the blood capillary compared to 40mmHg in the air. This forces air out of the blood into the alveoli to the air in the lungs.

During internal respiration, the partials pressure of 02 in the tissues is low 40mmHg,becaue of cellular respiration, but higher in the blood. Setting up partial gradient differences .Therefore 02 dissociates from the blood hemoglobin  to the tissues.

The reverse is the case for C02 which is of higher pressure gradient in the tissues than the blood. The set up a gradients that diffuses C02 from the tissues to the blood (opposite direction), carried by HB of the blood to the alveoli for onward diffusion into the air in the lungs.

The alveoli( air sac) is located in the lungs and served at the medium of gas exchange between the air in the lungs and the blood.

The cells of its wall are 1 cell layer thick made up of squamous epithelium; this reduces the diffusion distance and therefore aids diffusion.

The walls are usually moist so that the gases can readily dissolved in the moist lining for diffusion thus ensures 02 is at the same temperature with the body temperature.

The thin surface ensure high surface area to volume ratio, which increases the rate of diffusion.

They close to the pulmonary capillaries  to reduce diffusion distance.

These (partial pressure)  gradients ensures continuous availabity of the 02 in the blood tissues  and  the removal of C02 from the blood.

Two layers of smooth muscle form the small intestine. The outermost layer is the thin, longitudinal muscle that contracts, relaxes, shortens, and lengthens the gut allowing food to move in one direction. The innermost layer is a thicker, circular muscle.

Also smooth muscle is not under our control so is called involuntary

The frontal lobe is located infront of the brain and extends from the area located at the back of the forehead. It is responsible for higher cognitive functions like memory, emotions, impulse control, problem solving, social interaction, and motor function. The three frequently used techniques to measure the frontal lobe are Magnetic Resonance Imaging (MRI), magnetoencephalography (MEG) and electroencephalography (EEG).

Damage to the frontal lobe can cause several symptoms such as behavioral problems, depression, and loss of strenght in the muscles. Also conditions like stroke, head trauma, and dementia can be seen in individual with damage frontal lobe.

It is connected with a nerve pathways to other parts of the brain. It contains several structures like the anterior orbital gyrus, medial orbital gyrus, posterior orbutal gyrus, and gyrus rectus. the orbutal gyri which is connected to the vagus nerve plays an important role in the limbic system that controls emotional and automatic reactions.

When terrestrial predation pressures from snakes and wasps are strong, the tadpoles of red-eyed treefrogs (Agalychnis callidryas) should be selected to develop faster.

This is because in high predation environments, the risk of mortality from predation is high, and therefore, there is strong selection pressure for individuals that can reach the adult stage quickly and reproduce before being preyed upon. Tadpoles that develop faster are more likely to survive to the adult stage and pass on their genes to the next generation.Red-eyed treefrog tadpoles have been observed to exhibit plasticity in their developmental rates in response to the presence of predators. In the presence of predators, tadpoles tend to develop more quickly, whereas in the absence of predators, they tend to develop more slowly. This is an example of phenotypic plasticity, where the same genotype can produce different phenotypes in response to different environmental conditions.

Biological treatments of hazardous waste involve using plants, bacteria, or fungi to absorb and detoxify hazardous substances. The correct option is D.

Biological treatments of hazardous waste involve the use of living organisms, such as plants, bacteria, or fungi, to absorb and detoxify hazardous substances. This approach is known as bioremediation and is aimed at reducing or eliminating the harmful effects of hazardous waste on the environment.

In bioremediation, specific plants, bacteria, or fungi are selected for their ability to metabolize or break down the hazardous substances present in the waste. These organisms can absorb or take up the contaminants from the soil, water, or air, and through various biochemical processes, transform them into less toxic or non-toxic forms. This helps in the natural degradation and removal of hazardous substances from the environment.

Plants used in bioremediation, known as phytoremediation, can uptake and store contaminants in their roots, stems, leaves, or other plant parts. Bacteria and fungi, on the other hand, can directly degrade or transform the hazardous substances through enzymatic reactions.

Biological treatments offer several advantages, including their potential for low-cost and environmentally friendly solutions. They can be used to remediate contaminated soil, water bodies, or air, and have been applied in various industrial and environmental cleanup scenarios.

It's important to note that the specific approach and choice of organisms for bioremediation depend on the nature of the hazardous waste and the environmental conditions present at the site.

The concept that describes the partitioning of habitats through human-induced developmental activities is habitat fragmentation.

It refers to the division of habitats into smaller, isolated fragments as a result of human activities such as land-use changes, urbanization, deforestation, or road construction. Fragmentation often results in the creation of habitat islands, which are isolated fragments of habitat surrounded by a matrix of altered land. This can lead to changes in microclimate, soil quality, water flow, and other environmental factors that can impact the plant and animal species inhabiting the fragments. Therefore, habitat fragmentation is a significant threat to biodiversity conservation. It can lead to the loss of habitat connectivity, making it difficult for species to move between fragments or disperse to new areas. This can result in increased isolation of populations, genetic drift, and ultimately, a loss of biodiversity. The partitioning of habitats through human-induced developmental activities is a major factor that contributes to habitat fragmentation.

The primary functions of whales include feeding, reproduction, communication, and migration.

Whales are primarily filter feeders or predators, depending on the species.

Filter-feeding whales, such as baleen whales, have baleen plates in their mouths that allow them to filter out small prey, such as krill or small fish, from large volumes of water.

Predatory whales, such as toothed whales, hunt and feed on various marine organisms, including fish, squid, and marine mammals.

Reproduction is another important function for whales. Most whale species have a gestation period of several months, with females giving birth to a single calf.

The calves are nursed with milk from their mothers and rely on their care for a period of time until they become independent.

Communication is vital for whales, as they rely on vocalizations to communicate with other members of their pod.

Whales produce a variety of sounds, including songs, clicks, and whistles, which serve purposes such as mating, social interactions, and navigation.

Migration is a common behavior observed in many whale species. Whales undertake long-distance migrations, often covering thousands of kilometers, to reach feeding grounds in nutrient-rich waters or to reproduce in specific breeding areas.

These migrations are driven by seasonal changes in food availability and environmental conditions.

In summary, the primary functions of whales encompass feeding, reproduction, communication, and migration, all of which are essential for their survival and successful adaptation to their marine environments.

The statement "For every bacterial cell that undergoes sporulation, there are two resulting bacterial cells" is false. Sporulation is a process where some bacteria transform into a dormant state called a spore. Only one spore is produced per bacterial cell during sporulation.

Bacterial sporulation is a process where some bacteria convert to a dormant state called a spore. Sporulation can occur in some bacteria species under stress conditions such as a lack of nutrients. Sporulation starts when the bacterial cell divides into two unequal-sized compartments. One compartment is the smaller forespore while the other is the larger mother cell.

The mother cell engulfs the forespore within itself and forms a spore. Only one spore is produced per bacterial cell during sporulation. These spores can survive in harsh environments and then germinate into new bacterial cells when conditions are favorable again. Therefore, the statement "For every bacterial cell that undergoes sporulation, there are two resulting bacterial cells" is false.

Answer: The correct option is (the region of an enzyme that attaches to a substrate).

Explanation:

The anabolic and catabolic processes in a cell are directed and regulated by enzymes. An enzyme has the ability to speed up a metabolic reaction by lowering the amount of energy needed to start the reaction. Without enzymes, these processes would be extremely slow. They also arrange the reacting molecules in a manner that will cause the chemical change to take place rapidly. It does so through the following steps:

--> molecules of substrate combine with the enzyme at its active site.

--> the substrate molecules combine with enzyme molecules for a short time, forming an enzyme-substrate complex.

--> New substance ( product) is formed which leaves the active site of the enzyme thereby making it free for another reaction to take place.

In conclusion, the ACTIVE SITE of an enzyme is the region of an enzyme that attaches to a substrate allowing chemical reaction to take place.

Answer:

reactions by lowering activation energy.
