Describe: Fossil fuels are used in many ways. Using the Gizmo, describe the main use for each fuel.
Coal:
Petroleum:
Natural gas:
In each case, what is the end product of burning the fossil fuel, and where does it go?
Answer:
Coal:
Coal is primarily used as fuel to generate electric power
Petroleum:
heating and electricity generation, asphalt and road oil, and feedstocks for making the chemicals, plastics, and synthetic materials
Natural gas:
heating, cooking, and electricity generation.
it all end up in the atmosphere
Explanation:
The coal is burned and the heat given off is used to convert water into steam, which drives a turbine.
petroleum was formed from the remains of ancient marine organisms, such as plants, algae, and bacteria.
Like oil, natural gas is a product of decomposed organic matter, typically from ancient marine microorganisms, deposited over the past 550 million years. This organic material mixed with mud, silt, and sand on the sea floor, gradually becoming buried over time.
Coal and natural gas are burned in power plants to boil water. Steam from boiling water converts turbines into electricity. Carbon dioxide from burning fuel is released into the atmosphere.
This is about description of fossil fuels which are simply fuels that are formed from natural processes.
The uses and end products of fossil fuels are talked about in the explanations below;
1) (I) The primary use of the fossil fuel named coal is to generate electricity.ii) When coal is burnt, it produces a very high heat. This heat is so high that it converts water into high-pressure steam. What drives a turbine is a high pressure steam and this drive makes the turbine to produce electricity.
2) I) Petroleum products are used to set vehicles in motion, for asphalt on roads, production of electricity and heating of buildings.II) when petroleum is burnt to create energy, it produces high amount of carbon dioxide and other toxic gases into the atmosphere that can cause greenhouse effect.
3) I) Natural gas is used primarily as a source of energy for cooking, generating heat and for providing electricity.II) When it undergoes combustion is produces large amount of carbon dioxide and nitrogen oxides into the atmosphere.

A mother and father are curious about the possibility of having children of certain blood types. After some testing, the doctor tells them there is no chance that either of them will ever have a child with type O blood, no matter their partner. He does assure them that all of their children will have the same blood type. On the other hand, none of the children will have the same blood type as either the mother or the father. What blood type will the children be?
The blood type that the children won't have O blood type because the doctor says so and the children will not have the same blood type. This means that the children's blood type will likely be type A or Type B.
What does an increased pulse rate indicate about the heart rate
Answer:
A high heart rate can also mean the heart muscle is weakened by a virus or some other problem that forces it to beat more often to pump enough blood to the rest of the body. Usually, though, a high heart beat is not due to heart disease, because a wide variety of noncardiac factors can speed the heart rate.

A peony plant with straight stamens and red petals was crossed with another plant having straight stamens and streaky petals. The seeds were collected and germinated and the following offspring were obtained 62 straight stamens with red petals 59 straight stamens, streaky petals 18 incurved stamens, red petals 22 incurved stamens, streaky petals a) Which alleles in each pair are dominant
Answer:
Explanation:
From the given information.
Let the Straight stamens be S;
The incurved stamens be s;
The red petals be R; and
The streaky petals be r
The genotype of the parental plants are Straight stamens, red petals (SsRr) and Straight stamens, streaky petals)
So if SsRr and Ssrr crossed together, Then we have the following:
If SsRr self crossed, we have the following traits = SR Sr sR sr; &
Ssrr = Sr Sr sr sr
Then, the dihybrid cross is:
SR Sr sR sr
Sr SSRr SSrr SsRr Ssrr
Sr SSRr SSrr SsRr Ssrr
sr SsRr Ssrr ssRr ssrr
sr SsRr Ssrr ssRr ssrr
P(Straight stamens, red petals) = 8/16
P(Straight stamens, streaky petals) = 6/16
P(Incurved stamens, red petals ) = 2/16
P(Incurved stamens, streaky stamens) = 2/16
What novel characteristics are shared by gymnosperms and angiosperms but not by mosses and ferns?
Explanation:
Mosses go through sporophyte and gametophyte stages in their life cycle. ... However, mosses are nonvascular while ferns are vascular.

In the diagram below, which cells are involved in the process of sexual reproduction? A.) cell 3, only B.) cell 1 only C.) cell 1 and 2 D.) cell 2 and 3
Cell 1 and 2 are involved in the process of sexual reproduction which are sperm and egg respectively.
What are gametes?Gametes are reproductive cells that are responsible for sexual reproduction. In animals and plants, gametes are typically specialized cells that are specifically designed for the purpose of reproducing and transmitting genetic information from one generation to the next. Gametes are produced by the process of gametogenesis, which is the process of forming and developing gametes.
In animals, gametes are typically either eggs (ova) in females or sperm in males. Eggs are large, non-motile cells that contain a large amount of cytoplasm and nutrients to support the development of an embryo. Sperm are smaller, motile cells that are specialized for fertilization and are capable of swimming through the female reproductive tract to reach the egg.
In plants, gametes are typically produced by specialized cells called gametophytes. Gametophytes produce gametes through a process called meiosis, which is a type of cell division that results in the production of four genetically diverse daughter cells. The gametes produced by gametophytes are typically small and non-motile, and they are capable of fusing with gametes from other plants to produce a fertilized egg, or zygote.

What factors affect the likelihood a species will migrate from the mainland to an island?
Answer:
The factors that might affect the likelihood a species will migrate from the mainland to an island are the distance to the mainland and the island´s size.
Explanation:
Ecologists MacArthur and Wilson took the term island biogeography theory to refer to the predictions about the number of species that could inhabit an island.
Island biogeography theory establishes that the two factors that affect species richness in natural communities on an island are the distance to the mainland and the island´s size.
At the same time, these factors affect immigration and extinction rates. According to the theory, islands that are closer to the continent have higher possibilities of receiving immigrants than those located farther from the mainland. This is the effect of distance.
The effect of size is reflected in the relation between island size and species diversity. In smaller islands, the probability of extinction is higher than in bigger islands. Bigger islands can have more species than smaller ones.
In the case of two islands of the same size and different distance to the mainland, both of them will have the same extinction rate, but the one closer to the continent will have a higher immigration rate, and so, a higher amount of species. The S value will be higher on the island closer to the continent.

Answer: Magnolia is a large genus of about 210 flowering plant species in the subfamily Magnolioideae of the family Magnoliaceae. It is named after French botanist Pierre Magnol. Magnolia is an ancient genus. Appearing before bees did, the flowers are theorized to have evolved to encourage pollination by beetles. To avoid damage from pollinating beetles, the carpels of Magnolia flowers are extremely tough. Fossilized specimens of M. acuminata have been found dating to 20 million years ago, and of plants identifiably belonging to the Magnoliaceae date to 95 million years ago. Another aspect of Magnolia considered to represent an ancestral state is that the flower bud is enclosed in a bract rather than in sepals; the perianth parts are undifferentiated and called tepals rather than distinct sepals and petals. Magnolia shares the tepal characteristic with several other flowering plants near the base of the flowering plant lineage such as Amborella and Nymphaea.
Explanation:
The graph shows the effect of pH on the rate of reaction to three different enzymes. What does the graph show?
Answer:
Regarding the effect of pH on the reaction rate of three different enzymes, what the graph shows is that each enzyme works better at different pH (option A).
Explanation:
Enzymes are specialized protein molecules whose function is to contribute to faster reactions with lower activation energy. To fulfill this function, enzymes must be in an optimal range of temperature and pH.
The graph shows three enzymes, one in an acidic medium, one in a neutral medium and one in a basic medium. The reaction rate of each enzyme is similar, indicating that each is working at an optimum pH. The best interpretation that can be drawn from the graph is that each enzyme works best at a different pH.
The other options are not correct because:
B. The variable "temperature" is not included in the graph.
C and D. Since the comparison of the reaction rate of a single enzyme at different pH is not being made, the graph is not useful to indicate whether an enzyme works better in acidic or basic conditions.
