Blood type analysis is used frequently as evidence in paternity suits. Consider the following
hypothetical cases presented in the table. The blood type of the mother and child are given; indicate which
blood type(s) MUST be the father's for each situation.
Answer:
Row 1: Any blood type except AB
Row 2: Blood type A/AB
Row 3: Any blood type except AB
Row 4: Any blood type
Row 5: AB/B
Explanation:
1. If the blood type was AB for the first one (two dominant alleles) then O could not appear as it is recessive.
2. The blood type must contain at least one A allele as AB is obtained from I^A and I^B (already provided by the mother).
3. Once again, the blood type must carry at least one recessive O allele for the O blood type to occur in this child.
4. As long as the blood type either carries a recessive O or another B, the blood type will result in a B.
5. The blood type of the father must contain at least one B for the child to have a B blood type.

Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant
produced. THis is common in premature infants.
In healthy individuals, friction is a major factor affecting pulmonary ventilation
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.
Indicate whether each of the following statements is true of depurination (DP), deamination (DA), or pyrimidine dimer formation (DF). A given statement may be true of any, all, or none of these processes. This process is caused by spontaneous hydrolysis of a glycosidic bond. This process is induced by ultraviolet light. This can happen to guanine but not to cytosine. This can happen to thymine but not to adenine. This can happen to thymine but not to cytosine. Repair involves a DNA glycosylase. Repair involves an endonuclease. Repair involves DNA ligase. Repair depends on the existence of separate copies of the genetic information in the two strands of the double helix. Repair depends on cleavage of both strands of the double helix.
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.
Leigh's disease is a mitochondrially inherited disease with symptoms that include seizures, fatigue, impaired reflexes, breathing problems, and ataxia. The pedigree shows the presence of Leigh's disease in three generations. Individual 4 had two daughters and one son, and individual 6 had one daughter and two sons. Which of the individuals indicated are affected by Leigh's disease
About the question:
You will find the pedigree in the attached files
Answer:
individual 4 → Affected woman → Black circleindividual 5 → Affected woman or man → Black circle or squareindividual 7 → Healthy woman → Empty circleindividual 10 → Affected boy → Black SquareExplanation:
Mitochondrial inheritance is the transmission of a disease or a trait from the maternal line.
Most of the DNI is in the nucleus, but there is also DNI in mitochondria. Sperm cells hardly transfer mitochondrial genes to the progeny, so mitochondrial DNI is mostly inherited from the maternal side. If there exists any mutation in this mitochondrial DNI, the whole progeny of the mutated woman will be affected, as they will get the mother genotype carrying the mutation. On the contrary, if an affected man is carrying a mutation in mitochondrial DNI, non of their descendants will get the disease.
Before answering the question, let us remember the pedigree symbols.
Squares represent Males/Men Circles represent Females/WomenEmpty symbols represent healthy/non-affected individualsSolid black symbols represent sick/affected individualsIn the exposed pedigree, we can see that the mother is affected by the disease (individual number 2), so all her children are also affected (individuals 4, 5, and 6) because the disease is mitochondrially inherited.
Individual 3 is a healthy man, so individual 4 must be an affected woman (Black circle). As she is the one affected, then all her children will also be affected. This couple had one boy and two girls. Individuals 8 and 9 are girls (circle), so individual 10 must be the affected boy (black square).
On the other hand, individual 6 is an affected man (black square), son of individuals 1 and 2. This man couples with a woman, and they have all healthy children. So this woman (individual 7) must be healthy. Even though the man is affected, all their children are not because their mother (7) is not. Remember that sperm cells do not transmit the mitochondrial genes to the progeny.
And finally, individual number 5 might be either a man or a woman. In any case, this person is also affected by Leigh's disease.

Fish or mammals? Argumentation
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.
Write the argumentation between fish and mammals?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:
Fish: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.
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:
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.

i need some help on this.............
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.
