Answer:

Answer:

Biodiversity

Explanation:

The three options given don't seem to be correct...

Sustainability is how biological systems remain diverse and productive.

Ecological Footprint is the impact of human activities measured in terms of the area of biologically productive land and water required to produce the goods consumed and to assimilate the wastes generated.

Agriculture is the science of raising plants and/or animals for food, clothing or other useful products or the practice of cultivating the land or raising stock.

Answer 2

Answer:

Final answer:

Biodiversity is a term that describes the number and variety of species that live in an area. It contributes to the stability and balance of ecosystems and provides ecosystem services.

Explanation:

Biodiversity is a term that describes the number and variety of species that live in an area. It refers to the variety of life on Earth, including plants, animals, and microorganisms. Biodiversity is important because it contributes to the stability and balance of ecosystems, and provides ecosystem services such as pollination, nutrient recycling, and water purification.

A factory is emitting large amounts of CFCs into the atmosphere. How might this affect people?

Answers

CFCs stands for Chlorofluorocarbons. These compounds have long lifetimes. Because of its long lifetimes, it will not only affect our atmosphere but will also climbed to the higher spheres of earth, particularly our stratosphere.

The stratosphere is the location of our ozone layer. It protects us from the extreme rays of the sun. Prolonged presence of CFCs in the stratosphere destroys our ozone layer. Thus, weakening the protection from the sun's uv rays. This will affect us because we are subjected to higher risk of the sun's harmful ultraviolet rays which may result to skin cancer and other sun related ailments.

Answer:

Skin Cancer and other diseases caused by our depleting ozone layer

Terrance, whose birth mother drank heavily throughout pregnancy, has a thin upper lip, short eyelid openings, a small head, and a smooth philtrum. His physical growth has been slow, and he shows impairment in memory, attention span, motor coordination, and social skills. Terrance has __________. a. partial fetal alcohol syndrome
b. alcohol-related neurodevelopmental disorder
c. fetal alcohol syndrome
d. cytomegalovirus

Answers

Answer:

c. fetal alcohol syndrome

Explanation:

Fetal alcohol syndrome is the disorder that occurs in children who are exposed to alcohol during embryonic development due to alcohol consumption by their mothers.

Fetal alcohol syndrome is characterized by stunted growth of child and problems associated with the nervous system. Impaired neurological development makes these children slow learners and affects their motor skills.

Terrance's mother also consumed alcohol during pregnancy and exposed him to alcohol. His alcohol exposure resulted in fetal alcohol syndrome affecting his growth and mental development. Fetal alcohol syndrome also affects the shape and size of facial parts such as lips, eyelids, and head as exhibited by Terrance.

Find the amount of work done in emptying a cylindrical tank completely filled with kerosene. Assume that the radius of the cylindrical tank is 3 m, height is 6 m, and the density of kerosene is 817.15 kg/m3

Answers

The formula for the work done in emptying a tank is this:
W = ωyV

where
ω is the specific weight
y is the center of gravity
V is the volume of the liquid

The specific weight can be calculated using the formula
ω = ρg
where
ρ is the density
g is the acceleration due to gravity

Solving for ω
ω = 817.15 kg/m3 (9.81 m/s2)
ω = 8016.24 N/m3

The center of gravity of a completely filled cylindrical tank is just 1/2 of the height. So,
y = 3 cm

The volume of the kerosene is just the volume of tank. Using the formula for the volume of a cylinder
V = πr²h
V = π (3²) (6)
V = 54π m³

Therefore, the word done is
W = 8016.24 (6) (54π)
W = 8159538.47 J or
W = 8.16 MJ
