PLEASE HELP ME!!! I NEED THIS SO I CAN PASS MY CLASS AND I ONLY HAVE TEN MINS LEFT!!!! Comparing the four most common types of power plants in Alberta (coal, natural
gas, wind, and hydroelectric), which has the lowest efficiency in electricity
generation? and why?
Answer:
wind generated power plants. they have the lowest efficiency because it is not always windy and the wind varies everyday, thus the wind turbines will generate different amounts of electricity each day. They also can be very noisy and cause noise pollution. Wind Plants need good land place and these are mainly found in rural areas far from the city that the electricity is needed.

How do clastic rocks get different sizes of particles?
Answer:
Such material, called detritus, consists of fragments of rocks and minerals. When the energy of the transporting current is not strong enough to carry these particles, the particles drop out in the process of sedimentation. This type of sedimentary deposition is referred to as clastic sedimentation.

Explanation:
Terrestrial planets are Earth, Mercury, Venus, Earth, Mars planets whereas Jupiter, Saturn, Uranus and Neptune are Jovian planets which is also called gas giants. Terrestrial planets means that the planets have rocky soil which is hard in nature while on the other hand, a gas giant is a big planet that is composed of mainly hydrogen and helium element so we can conclude that terrestrial planets are different from gas giant in their soil composition.
Four differences between the aorta and vena cava ?
Answer:
Aorta and vena cava are two main types of blood vessels attached to the heart. The main difference between aorta and vena cava is that aorta carries oxygenated blood whereas vena cava carries deoxygenated blood. Aorta is the main artery that leaves the heart through the left ventricle. It supplies oxygenated blood throughout the body. Two types of venae cavae supply blood to the right atrium of the heart. They are superior vena cava and inferior vena cava. Superior vena cava drains deoxygenated blood from the head, arms, and other upper parts of the body while inferior vena cava drains that from the lower parts of the body.
Reason why two species of plant cannot interbreed because their flowers differ in size and shape and require pollination by different species of bee
Answer:
Due to difference in size and shape of flower.
Explanation:
Two species of plant cannot interbreed with each other because their flowers differ in size and shape. Each flower has different time of maturation and the appearance of reproductive stage as well as difference in their chromosome number. If these factors occurs on the same time and having same number of chromosomes so they are able to interbreed with each other otherwise not so that's why we can say that two species can't interbreed with each other.

How is biodiversity impacted by palm oil plantations?Palm oil plantations provide habitats to several species, so they do not cause habitat fragmentation.Palm oil plantations have fewer habitats, niches, trophic levels, and communities, resulting in a weak ecosystem.Without global extinction, species extirpation has little impact on its ecosystem in palm oil plantations.Removal of predators in palm oil plantations promotes survival of other species and therefore species diversity.In palm oil plantations, only one tree species and few canopy plants are allowed to grow.
Answer:
Palm oil plantations have lesser habitats, communities, trophic levels, and niches that result in weak ecosystems.
Explanation:
Oil palm plantation is a crop that is high in demand for the extraction of palm oil used for various purposes like the formation of soaps, cleaning products, washing powder, and production of food products.
Oil palm plantation is mainly responsible for deforestation, pollution, and habitat fragmentation. Trees are grown at a particular distance and neighboring other species are removed so that the palm trees receive the nutrients from the soil and it will also facilitate easy harvest. Only one tree species is palm tree allowed to grow and other species are restricted as they can mask the sunlight by their canopy making it unavailable for oil palm plants.
Thus due to habitat fragmentation involving discontinuity in an organism's preferred environment of survival fewer habitats of species can be found as few species which can inhabit the oil palm plants can survive, and the ecosystem becomes weak. As the species are interdependent on each other for food needs. The low number of plant species will reduce the population of faunal species from the location. The functional roles or niches are affected by species, the whole biotic community or ecosystem gets disturbed. This will reduce the population of the species and reduce the overall biodiversity of a region.
All of the following are true about the structure of DNA excepta.
a. the long strands of nucleotides are twisted into a double helix.
b. short strands of DNA are contained in chromosomes inside the nucleus of a cell.
c. DNA consists of two strands of nucleotides joined by hydrogen bonds.
d. every DNA nucleotide contains a sugar, a phosphate group, and a nitrogen base.
Answer:
short strands of DNA are contained in chromosomes inside the nucleus of a cell.
Explanation:
DNA is an acronym for deoxyribonucleic acid. It is composed of a sugar, a phosphate group, and a nitrogen base.
DNA consists of two strands of nucleotides joined by hydrogen bonds. This makes DNA appear in a double helical structure.
Long strands of DNA are contained in chromosomes inside the nucleus of a cell. Long strands of DNA in the nucleus are rolled into neat little bundles. Hence the statement; ''short strands of DNA are contained in chromosomes inside the nucleus of a cell'' is false.

6. Because they are embedded within the membrane, ion channels are examples of ________. receptor proteins integral proteins peripheral proteins glycoproteins 7. The diffusion of substances within a solution tends to move those substances ________ their ________ gradient. up; electrical up; electrochemical down; pressure down; concentration 8. Ion pumps and phagocytosis are both examples of ________. endocytosis passive transport active transport facilitated diffusion 9. Choose the answer that best completes the following analogy: Diffusion is to ________ as endocytosis is to ________. filtration; phagocytosis osmosis; pinocytosis solutes; fluid gradient; chemical energy
Answer:
6. integral proteins
7. down; concentration
8. active transport
9. osmosis; pinocytosis
Explanation:
An integral protein is a protein that is permanently attached to a biological membrane. Some examples of integral membrane proteins include, for example, the insulin receptor, cell adhesion proteins (e.g., integrins), glucose permease, etc. Diffusion, also known as passive transport, refers to the process by which a substance/molecule tends to move from an area of high concentration to an area of low concentration. Moreover, osmosis is a type of diffusion by which a solvent (e.g., water) moves across a semipermeable membrane from a region of lower concentration to a region of higher concentration. Active transport refers to the movement of molecules/substances across a biological membrane against a concentration gradient. There are two types of active transport: primary active transport and secondary active transport. The primary active transport depends on a source of energy (e.g., ATP) for movement, whereas secondary active transport depends on electrochemical gradients to transport substances with the help of membrane transport proteins (i.e., cotransporters). Active transport involves ATP pumps that move ions into and out of the cell. Finally, endocytosis is the process by which cells absorb external material by engulfing them in transport vesicles, whereas pinocytosis refers to a type of endocytosis involving fluids that contain many solutes.
When you have diabetes what is the main body system that is being affected? How does it affect other systems?
Answer:
the main body system is circulatory system?
Answer:
The Circulatory System (Read explanation)
Explanation:
Diabetes affects many of the body's major organs, such as the kidneys, eyes, blood vessels, and heart. Kidney Damage The kidneys filter out your body's waste products. In diabetics, high levels of blood sugar force the kidneys to try to filter large quantities of blood.
It affects other systems because kidneys are technically part of the urinary system and if you have diabetes, it will indeed affect the urinary system. It is all linked together and the domino effect will collapse.

How do you relate energy from heat?
In a strictly physical sense, the only difference between thermal energy and heat is that heat is currently in transit. For example, the warmth radiating from a fire.
While heat is a “path function”, thermal energy can be a “point function” as it can have a defined value at a specific state. Numerically, Δ(Thermal Energy) = Heat Exchanged.

Which is a disadvantage of a natural-gas-burning power plant compared to a
renewable-energy plant?
A. It is more expensive.
B. It produces less energy.
C. It releases greenhouse gases.
D. It can only be used in certain areas.
Answer:
A. it is more expensive
Explanation:
This is why we still rely on natural gas because renewable energy is taxing to the economy.
Natural-gas-burning power plants use fossil fuels and are at disadvantage compared to the renewable-energy plant. The burning of natural gases produces greenhouse gases. Thus, option C is correct.
What is renewable energy?Renewable energy is the use of sources that are infinite and are less harmful to the environment compared to non-renewable energy resources. They uses efficient energy sources that does not contribute to greenhouse gases.
Non-renewable resources like the natural-gas-burning power plant are harmful to use over a long period of time as they release a lot of carbon dioxide that adds to the greenhouse resulting in global warming and increased temperature.
Therefore, option C. the natural-gas-burning power plant releases greenhouse gases.
