1. The burning of fossil fuels contributes to all of the following ecological problems except for:
A. ozone depletion
B. global warming
C. acid rain
D. air pollution
The burning of fossil fuels does not contribute to ozone layer depletion.
The burning of fossil fuels leads to the release of gases such as oxides of nitrogen, sulfur, and carbon as well as particulate matter such as smoke, ashes, etc.
The oxides released from fossil fuel burning can cause global warming (carbon dioxide), acid rain (SO2), and air pollution (particulate matter).
Ozone layer depletion is caused by pollutants such as halocarbons, solvents, etc.

Proteins are synthesized based on genetic information carried by DNA. Explain In you’re own words how the structure of DNA is important in the
synthasis of different kinds of proteins, In your explanation, include a description of the two main processes involved in
protein synthesis.
Answer:
Explanation:The synthesis of proteins occurs in two sequential steps: Transcription and Translation. Transcription occurs in the cell nucleus and uses the base sequence of DNA to produce mRNA. The mRNA carries the message for making a specific protein out to the cytoplasm where translation occurs.
What is the most valid conclusion regarding ocean depth temperature, based on the data? The temperature and salinity increase with increasing depth. The salinity increases as the depth goes closer to zero. The bottom of the ocean is frozen and salinity levels are low. The ocean temperature never rises above 10°C and salinity remains constant.
The most valid conclusion concerning ocean depth temperature is B. The salinity increases as the depth go closer to zero.
Effect of Salinity on Water Depth
Decreasing ocean temperature increases ocean salinity. These occurrences put pressure on water as the water depth increases with decreasing temperature and increased salinity.
What is Ocean Salinity?
Ocean Salinity refers to the saltiness or amount of salt dissolved in a body of water. The salt dissolution comes from runoff from land rocks and openings in the seafloor, caused by the slightly acidic nature of rainwater.
Thus, the most valid conclusion one can draw regarding ocean depth temperature is Option B.

Which of the following ecological levels does not describe interacting biotic and abiotic factors in an area?
A. Biome
B. Community
C. Ecosystem
D. Habitat
Answer:
habitat
Explanation:
The ecological levels do not describe interacting biotic and abiotic factors in an area's habitat. The correct option is D.
What is a habitat?
A habitat is a place where physical or biotic factors are presented. This is a place where all the factors are present to live a species with all suitable conditions.
Habitat of different species is different. They live in their suitable habitat to grow and reproduce accordingly. If a species is moved from its habitat, then it may have difficulties in surviving.
So habitat is not a place where all biotic and species abiotic factors are present, it is a place where all living factors are present that are necessary for the living of a person. So, it is not the ecological level of interacting biotic and abiotic factors in an area
Thus, the correct option is D. Habitat.

An instrument is gradually lowered beneath the surface of the ocean to measure the temperature and salinity of the water. The graphs below show the change in temperature at each depth in kilometers below the surface.
Image of two graphs. The left graph has the x axis labeled temperature degree C ranging from 0 to 10. The y axis is labeled depth below surface, km, ranging from negative 1.8 to 0. The line on graph goes up vertically starting at about 2 degree C on the x axis and negative 1.9 km on the y axis. The vertical line goes up staying at about 2 degree C and climbs from negative 1.9 km to about negative 0.8 km. The line starts to shift right at negative 0.6 km. The line shifts to the right from 2 degree C to 5 degree C. The line shifts to right more starting at negative 0.5 km and reaches 10 degree C around negative 0.2 km. The line continues up vertically after negative 0.2 km. The right graph has the x axis labeled salinity ranging from 33.8 to 34.6. The y axis is labeled depth below surface, km, ranging from negative 1.8 to 0. The line on the graph starts at 34 on the x axis and 0 km on the y axis. The line starts to shift to the right at negative 0.1 km and levels out at 34.2 on the x axis. At negative 0.2 km the line shifts to the left and continues to shift left until it reaches negative 0.5 km. The line starts to shift to the right again at negative 0.6 and continues to shift right until it reaches negative 1.9 km on the y axis and 34.6 on the x axis.

What is an ocean?
An ocean is a large body of salt water. The oceans are divided into seven kinds. But they are interconnected to each other. The ocean is the largest water body, and it is also present in the form of freeze blocks of ice.
The graph is given of the temperature and salinity of the ocean, with the depth of the ocean the temperature of the ocean decreases, and the salinity increases.
The salinity of the water represents the presence of salt in the oceans. It. the graph proves that the salinity increases with the depth, coming closer to the depth.
Thus, the correct option is B.) The salinity increases as the depth goes closer to zero.

4. How does the life of a sperm cell vary among the mosses, ferns, gymnosperms and angiosperms?
Answer:
They evolved on land to begin with from earlier now extinct groups groups so there was no need to adapt to life on land, other than to adapt to different terrestrial environmental pressures. Land can be everything from next to a river to a hot desert to rocks to Antarctica, and plants grow in all those places.
As well, there are thousands of species that are floating aquatics or submerged aquatics, including many ferns, and even some gymnosperms grow as marginals, and many species of angiosperms, mosses, ferns, and even some gmnosperms grow as epiphytes, or as parasites, or other ways.

Relative dating
Radiometric dating
Scientists can determine the exact age of a fossil by a technique called Radiometric dating. Radiocarbon dating involves the determination of how much carbon is left in the fossil.
In radiocarbon dating, it is possible to determine how much carbon is left in the fossil, by looking at its half-life period.
Radiocarbon dating (also known as carbon dating) refers to the technique aimed at determining the age of a fossil by exploring the properties of a radioactive carbon isotope called radiocarbon.
Radiocarbon or carbon-14 (14C) is a radioactive carbon isotope of carbon that contains 6 protons and 8 neutrons, whose amount in a sample can de be used to determine the age of a given organic material.

How does the air pressure at sea level compare with air pressure at higher elevations such as
Mt. Everest. In your explanation include information about the number of air molecules in a
parcel of air at that altitude and the affect of gravity on pressure at both altitudes.
Answer:
Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.In addition, gravity is weaker at the equator due to centrifugal forces produced by the planet's rotation. It's also weaker at higher altitudes, further from Earth's centre, such as at the summit of Mount Everest

If white wool (W) is dominant over black wool (w), can two sheep with black wool produce an offspring with white wool? Explain your answer.
Answer:
No, the offspring of two black sheep cannot have white wool. Since the black wool allele is recessive, both parents have to be recessive (ww) and so do not carry the dominant white wool allele. The only allele the parents can pass to their offspring is the black allele.
