Protecting shoreline communities from tsunamis is a struggle, especially in less developed regions of the world. Explain why your experiment supports this statement.
Answers
Protecting shoreline communities from tsunamis is a struggle, especially in less developed regions of the world because tsunamis are unpredictable. These phenomena have a higher effect on low-income shoreline families.
Tsunamis can be defined as giant ocean waves due to earthquakes and/or volcanic activity that occur under the sea.
Tsunamis may devastate entire shoreline communities because they are unpredictable and they speed along like a jet plane.
Tsunamis mainly affect shoreline low-income families in developing countries because the houses in which these people live in developing countries are rudimentary.

Unpasteurized milk or milk products can result in food-borne illnesses.
What are foodborne illnesses?Foods can be contaminated by a wide range of disease-causing microbes, leading to a wide range of foodborne diseases, commonly known as foodborne sickness or food poisoning.
Over 250 foodborne illnesses have been uncovered by researchers. Numerous bacteria, viruses, and parasites are to blame for the majority of them, which are infections. Foodborne illnesses can also be brought on by toxins and chemicals contaminating foods.
Foodborne illnesses frequently cause nausea, vomiting, stomach cramps, and diarrhea. The symptoms of many foodborne infections, however, may vary. Sometimes, foodborne infections can have severe symptoms, and some of them can even be fatal. A foodborne disease may affect anybody, but certain people are more susceptible to getting one.
The majority of people who contract a foodborne disease recover on their own, but those who experience severe symptoms should visit a doctor.
Therefore, unpasteurized milk or milk products can result in food-borne illnesses.

Answers
Sociologists argue that the division of the human population into two distinctive and mutually exclusive categories, male and female, is best understood as a biological fact.
The division into these two major categories as male or female is mainly due to the biological and the physiological characteristics produced in both male and female.
Although in some cases, it may be argued that they are not mutually exclusive as there are some who have both.
Nevertheless, the above mentioned characteristics are just used to differentiate between a male and a female in humans and as well an individual self-concept of being a male or a female.

The eyes of some birds contain cells that detect ultraviolet (UV) light.
UV light is reflected by some fruits and the urine of small mammals.
Explain how birds that detect UV light have evolved from birds that could not detect
UV light
[6 marks
Answers
Birds that detect UV light have favorable characteristics that enable them to survive and reproduce. These characteristics are passed on to their offspring.
According to Darwin's theory of evolution, organisms that are better adapted to their environment live long enough to survive and reproduce and pass on these favorable traits to their offspring.
Since birds depend on these fruits for food and these fruits reflect UV light. A bird that can not detect UV light will find it difficult to obtain food. Hence, birds that have developed the ability to detect UV light will live long enough and reproduce, passing on these favorable characteristics to their offspring. Hence, birds that can detect UV light appears from birds who do not originally detect UV light.

five (5) kidney diseases their symptoms and their effect
Answers
Answer:
Kidney failure occurs when your kidneys lose the ability to sufficiently filter waste from your blood. Many factors can interfere with your kidney health and function, such as:
toxic exposure to environmental pollutants or certain medications
certain acute and chronic diseases
severe dehydration
kidney trauma
Your body becomes overloaded with toxins if your kidneys can’t do their regular job. This can lead to kidney failure, which can be life-threatening if left untreated.
Usually, someone with kidney failure will have a few symptoms of the disease. Sometimes no symptoms are present. Possible symptoms include:
a reduced amount of urine
swelling of your legs, ankles, and feet from retention of fluids caused by the failure of the kidneys to eliminate water waste
unexplained shortness of breath
excessive drowsiness or fatigue
persistent nausea
confusion
pain or pressure in your chest
seizures
coma
Symptoms of early-stage kidney disease may be difficult to pinpoint. They’re often subtle and hard to identify. If you experience early signs of kidney disease, they may include:
decreased urine output
fluid retention that leads to swelling in limbs
shortness of breath
A sudden loss of blood flow to your kidneys can prompt kidney failure. Some conditions that cause loss of blood flow to the kidneys include:
a heart attack
heart disease
scarring of the liver or liver failure
dehydration
a severe burn
an allergic reaction
a severe infection, such as sepsis
High blood pressure and anti-inflammatory medications can also limit blood flow.
When your body can’t eliminate urine, toxins build up and overload the kidneys. Some cancers can block the urine passageways, such as:
prostate (a most common type in men)
colon
cervical
bladder
Other conditions can interfere with urination and possibly lead to kidney failure, including:
kidney stones
an enlarged prostate
blood clots within your urinary tract
damage to your nerves that control your bladder
Acute intrinsic kidney failure can result from direct trauma to the kidneys, such as physical impact or an accident. Causes also include toxin overload and ischemia, which is a lack of oxygen to the kidneys.
The following may cause ischemia:
severe bleeding
shock
renal blood vessel obstruction
glomerulonephritis

A local watershed carries runoff from farms, suburban lawns, and wastewater treatment plants into local rivers, and eventually into a local bay. How could this affect the health of the bay?
A. It could make water hypoxic for organisms.
B. There will be an increase of aquatic plants and fish.
C. It could increase dissolved oxygen for fish.
D. There will be decreased nutrients in the water.
Answers
Answer:
answer should be "making water hypoxic for organisms". reason is because the runoff from these treatment plants are filled with nutrients, which will cause eutrophication. eutrophication is excessive algae sprouts which create more DO but then later becomes all used up when they decompose, making it so other organisms have no oxygen.
The runoff water from farms, suburban lawns, and wastewater treatment plants into local rivers affects the health of the bay by making water more hypoxic for organisms. Thus, the correct option is A.
What is Local bay?A Local bay may be defined as an area of the sea or other water bodies which are usually smaller than a gulf. It is mostly surrounded by water.
The runoff water from farms, suburban lawns, and wastewater treatment plants contain an enormous amount of nutrients that assist the growth of algae over the surface of water bodies known as eutrophication.
These algae consume all much of the available oxygen of the water body and make the environment hypoxic i.e. oxygen deficient.
Therefore, the correct option for this question is A.
