The increasing demands for fossil fuels has led governments and businesses to
consider several possibilities to solve the energy crisis. Which solution will reduce the
impact of this crisis on the environment and future generations?
(1) increase the number of drilling sites for crude oil in North America
(2) build more power plants away from population centers
(3) limit the number of people in each vehicle
(4) develop alternative fuel sources that can be produced from renewable
resources
The rise of fossil fuels demands various nations has created problems for the government to meet the increasing supplies as fossil fuels are fast depleting and heavily pollute the environment at large.
The government is trying to build more alternative fuel sources and produce some renewable resources in case of fossil fuels get depleted completely.Hence the option 4 is correct.

Explain why the blood vessels and the heart are not made of the same type of muscle even though they are both involuntary.
Answer:Each muscle in the body is made up of cells called muscle fibers. Muscle fibers are long, thin cells that can do something that other cells cannot do—they are able to get shorter.
Explanation:
IM not sure if this would help but their you go.
Muscle fibers are the cells that make up each muscle in the body. Muscle fibers are long, thin cells with the unique ability to shrink. Most cells cannot do this.
What are Muscle fibers?Cross-striations are the most noticeable histological characteristic of muscle fibres, which are massive multinucleated cells. Many myofibrils with tiny cylinders made of bundle of myofilaments can be found in the cytoplasm.
Myofilaments are made up of both thick filaments primarily made of myosin and thin filaments primarily made of actin. Due to their regular overlap, which is kept in register from across diameter of the muscle fiber, the thick and thin filaments create the cross-striations.
Thus, the cells that make up each muscle in the body are known as muscle fibres. Long, thin cells called muscle fibres have the unusual ability to contract and expand. Most cells are unable to achieve this.

The first trophic stage of a food chain, which contains the most energy, is made up of the green plants with in ecosystem known as producers.
What is Trophic level of Food chain?The term "trophic level" refers to an organism's place in the food chain and has a range of one for primary producers to 5 for humans and marine mammals. The mean trophic level of the consumer's prey is multiplied by one to determine the consumer's trophic level.
The trophic levels are divisions into which species in food webs get categorised. These levels can be roughly categorised as producers (first trophic level), consumers, and decomposers (last trophic level). The first trophic level is producers. The first trophic level receives 100% of the energy from the sun, which has the greatest amount of energy, while subsequent trophic levels only receive 10% of the energy of the level before them.
Thus, the first trophic stage of a food chain, which contains the most energy, is made up of the green plants with in ecosystem known as producers.

Ecosystems Unit Test 8 of 8 Items Item 8 Discuss an ecosystem in which there is a producer, a consumer, a secondary consumer, and a decomposer. Name the ecosystem and specific organisms for a producer, consumer, secondary consumer, and decomposer
Answer:
The ecosystem, in this case, is a forest. The producers are plants. The deer, who eats the plants, is the consumer. The wolf, who eats the deer, is the secondary consumer, and earthworms are the decomposers.
Explanation:
An ecosystem is a group of beings that are in a certain area where they interact with each other and with their surroundings. In this case, we describe a trophic level with beings that are in the forest.
Producers are beings that produce their food, like plants.Consumers or primary consumers are animals that eat producers. They are herbivores.Secondary consumers eat primary consumers. They can be omnivores, or like in this case, carnivores.Decomposers are bacterias, mushrooms, or earthworms. They act on all levels breaking down the rest of the animals and plants, obtaining nutrients to nourish the soil, and start the cycle again.Which of the following is an example of descent with modification
This will lead to change in populations over generations in a process that Darwin called descent with modification. ... One of the best examples has been demonstrated in the very birds that helped to inspire Darwin's theory: the Galápagos finches.
a mechanism for evolution; all organisms are related through descent from an ancestor; descendants accumulated adaptations; descent of all organisms from an ancestor that lived in the past; descendants accumulated diverse modifications (adaptations)
if the first one doesnt work try the second
An example of descent with modification is a bacterium that inherits a gene for antibiotic resistance, has a more significant possibility of survival. Natural selection then applies that resistance through the population, forcing scientists to come up with a new antibiotic.
What is darwin's theory of descent with modification?Darwin described evolution as "descent with modification," the theory that species evolve over time, give rise to new species and transmit a common progenitor.
The means that Darwin proposed for evolution is natural selection.
Thus, a bacterium that inherits a gene for antibiotic resistance, is an example of descent with modification.

An egg, a model of a cell, is placed in a concentrated sugar solution (hypertonic) for 24 hours.
What will happen to the egg? The egg will
1. lose mass and shrink in size
2. gain mass and increase in size.
3. stay the same mass and size.
Answer:
gain mass and increase in size
Answer:
1. lose mass and shrink in size
Explanation
the egg is a more dilute solution that the one it is placed in. Through osmosis it will lose water until both solution(the inside and outside of the egg) have roughly the same concentrations. Losing water will cause it to shrink.
What is the importance of cell membranes to supporting life?

The artificial cell in the picture below is permeable to monosaccharides but not polysaccharides. Initially, the artificial cell contained a solution of glucose and starch while the beaker was filled with only water. After a period of thirty minutes, the water solution in the beaker tested positive for glucose. What process allowed for this to occur?
Answer:
Osmosis.
Explanation:
Osmosis is the process which is responsible for the transportation of glucose inside the cell. Osmosis is a process in which micro-molecules such as glucose, ions and gases etc go inside the cell through a semi-permeable membrane. This semi-permeable membrane of the cell only allow monosaccharides but not polysaccharides because monosaccharides is small in size while polysaccharides are larger in size.
