Explanation:

Answer: Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant  produced. This is common in premature infants.

Explanation:

Infant Respiratory Distress Syndrome (RDS) occurs in new born infants whose lungs are unable to produce the enough surfactant to keep their lungs expanded which would enable them to breathe properly after delivery.

It is most common in premature infants because surfactant is produced in the third trimester of pregnancy so premature infants might not get the chance to produce enough before the are delivered. RDS needs to be treated as soon as possible or else a baby could suffer damage to the brain and other vital organs.

Answer:

Weak.

Explanation:

The Philippines is a weak and financially poor country due to its current condition. The main reason for its weak state is due to the poor economy that is responsible for its weak state. The environment is not favourable for the investors and business due to costly facilities that prevent the investors to invest in the country. If the environment for the investor is good so the investors come to the country and contributes in the economy which make the financial situation of the country better.

Answer:

- This process is caused by spontaneous hydrolysis of a glycosidic bond: depurination and deamination

- This process is induced by ultraviolet light:  pyrimidine dimer formation

- This can happen to guanine but not to cytosine: depurination

- This can happen to thymine but not to adenine:  pyrimidine dimer formation

- This can happen to thymine but not to cytosine: none

- Repair involves a DNA glycosylase: deamination

- Repair involves an endonuclease: depurination, deamination and  pyrimidine dimer formation

- Repair involves DNA ligase: depurination, deamination and  pyrimidine dimer formation

-  Repair depends on the existence of separate copies of the genetic information in the two strands of the double helix: depurination, deamination and  pyrimidine dimer formation

- Repair depends on cleavage of both strands of the double helix: none

Explanation:

Depurination is the loss of purine bases (either adenine or guanine), while deamination refers to the removal of an amino group. During depurination, a β-N-glycosidic bond is cleaved by hydrolysis and a nucleic base is released (either adenine or guanine). All DNA bases may undergo deamination, except thymine (since thymine does not have an amino group). The ultraviolet (UV) radiation can cause thymine or cytosine to form dimers (e.g., pyrimidine dimers), being thymine dimers the most common lesion when DNA is exposed to UV light. Pyrimidine dimers may be repaired by different excision mechanisms, e.g., nucleotide excision repair, where the recognition of the DNA damage leads to the removal of the DNA fragment containing the lesion. DNA glycosylases are enzymes involved in the mechanism of base excision, these enzymes recognize and remove damaged bases by hydrolysis of the glycosidic bond, producing an abasic (apurinic and apyrimidinic) site. A DNA ligase enzyme covalently joins two DNA molecules by forming a phosphodiester bond, which is required during these processes.

While mammals are better suited for life on land due to several advantages, fish have several adaptations that make them suitable for life in water.

Both fish and mammals are diverse groups with their own specialized adaptations and traits, making direct comparisons between them challenging. Here are some arguments for and against each, though:

Argument for: Fish have streamlined bodies that make swimming more effective and gills that allow them to extract oxygen from the water, making them well adapted to living in water.

Argument against: Fishes often have less complex and intellectual anatomy and behavior than mammals.

Arguments in favor of mammals: Mammals have a greater range of body size and form than fish and adaptations for movement, such as the ability to run, jump, or climb.

Arguments Against: Due to their low buoyancy and inefficient swimming bodies, mammals are less adapted to living in water than fish.

The ultimate determination of which is "better" - fish or mammals - depends on the context and standards being used. Both groups have evolved to occupy a wide variety of ecological regions, but each has its own distinct advantages and disadvantages.

Therefore, while mammals are better suited for life on land due to several advantages, fish have several adaptations that make them suitable for life in water.

Answer:

a) Beaver-dam buildings → (iii) Pond floods

b) Forest fire → (i) New plants can grow because of an increase in sunlight on the forest floor

c) Lack of rainfall  →  (ii) Zebras migrate farther to find water holes

d) Invasive water plants arrive →  (iv) Sunlight is blocked for native seagrasses

e) Grasshopper outbreaks  →   (v) Crops are wiped out along the prairie

f) Coyote disease decreases the population →  (vi) Mice population explodes

Explanation:

a) Beaver-dam buildings → (iii) Pond floods

This is an example of how some species might produce damages in ecosystems. Beavers are known for their dams, where they hide from predators, find shelter, reproduce, and feed. With time, and as the beaver population grows, these dams get bigger each time. These animals keep cutting down trees and covering some wider areas that were inhabited previously by other species. The landscape changes, these areas get flooded permanently, most vegetation dye, the soil properties get altered, and just a few species can keep living there. The ecosystem changes.

b) Forest fire → (i) New plants can grow because of an increase in sunlight on the forest floor

This is an example of biological succession. Stable forests characterize as having big old trees that compete for light developing big canopies at heights. Poor light reaches the ground and allows some smaller species to grow. When a fire occurs, some of these trees might fall or disappear. These fire events open windows in the forest through which sunlight directly reaches the ground. Many new species can germinate and grow. There occurs a renovation of vegetable species in the forest and the consequent renovation of other living forms.  

c) Lack of rainfall  →  (ii) Zebras migrate farther to find water holes

It is not unusual that some species need to migrate looking for food or water. In certain areas, seasonal differences are very sharp, and while some periods characterize as producing plenty of food and water, some others characterize as lacking them, dry seasons especially. Animals develop different strategies to face these moments. Zebras need to migrate to find a new source of water to ensure proper hydration.

d) Invasive water plants arrive →  (iv) Sunlight is blocked for native seagrasses

A very known global environmental problem is the damage caused by invasive species. In a few words, exotic species arrive in a new area out of their native distribution range, establish, grow, adapt, and reproduce. These exotic species turn into invasive species when they overgrow, sharply increasing their reproductive rate. At this point, interaction with native species becomes harder, competing for resources such as space, light, food, shelter, water, among many others. Invasive species become such a good competitor that end by displacing native species. In the exposed example, invasive water plants arrive, and their population overgrows. They compete for light with native seagrasses and end by blocking it for them.

e) Grasshopper outbreaks  →   (v) Crops are wiped out along the prairie

This is an example of the prey-predator relationship. In this case, grasshoppers are the predators, and crops are acting as the prey. Whenever one of the population increases in size, the other one follows this increase, causing the decrease of the first one. When the first population decreases, the second one also decreases. In this example, grasshopper outbreaks, meaning an increase in predation rate over crops. Many more individuals are feeding on the crops, causing more damages to the plants´ population. Crops do not have enough time to recover, so they are wiped out.

f) Coyote disease decreases the population →  (vi) Mice population explodes

This is also an example of the prey-predator relationship. In this case, coyotes are the predators, and mice are acting as the prey. As coyotes are affected by the disease, which causes a decrease in their population size, mice seem to be favored, as they are not predated. They have enough time to recover as a population and increase in size. Coyotes´population decreases in size, so there are many fewer individuals feeding on mice, and hence, the mice population increases very fast. It explodes.
