3.what colour does the clear alcohol become once the leaf is boiled in it? Explain why?
Answer:
We boil the leaf in alcohol when we are testing it for starch because to remove the green pigment chlorophyll present in it. For the starch test, we need to observe the colour change from brown to blue when iodine is put on the leaf.Using a textbook, define the following Ecology terms:

Explanation:
I searched this from the web and based on that you can write it in your own words. Please understand that I don't have the text book.
Answer each question, using it as an opportunity to illustrate the depth of your knowledge in this area.
1. One of the fundamental controls which ecosystems exert over individual species is limits on population size. This is done by a combination of predatory, competitive, parasitic and mutualistic relationships within the ecosystem. Never the less, the human population has increased well beyond what is healthy for those systems. How did we manage to grow beyond these limitations?
2. Natural variations in weather patterns have effects on certain populations. A warm damp spring for example, is ideal for small rodent species and certain insects, who benefit from the lush vegetation produced by this pattern. As a result, their populations swell to high levels. In the end however, this doesn't result in population growth at the higher tropic levels. You don't end up with more predators, just fatter predators. What limits the ability of the higher tropic levels to grow in response to the increased availability of food?
3. An unfortunate series of events finds you stranded on a remote uninhabited south Pacific island, with little chance of being rescued. It is a modest-sized island with adequate resources to support you, if you are careful to minimize your impact on it. You know that inserting yourself into this ecosystem will almost certainly mean the loss of members in some populations, so your goal is to minimize your impact on the overall biodiversity of the system. With this in mind, from which tropic level(s) should you obtain your food?
Answer:
1. Humans are an “invasive species” because human populations have eliminated many ecological relationships, dramatically changing the dynamic of their ecosystems
2. continued loss of energy due to metabolic activities
3. lower trophic levels
Explanation:
1. An invasive species is any organism that is not native to an ecosystem and may negatively alter its new environment. Invasive species don't interact with native species when they are introduced into an ecosystem (for example, invasive species usually don't have any natural predators). Humans are an 'invasive species' that occupy a wide range of habitats and whose presence has caused the extinction of many native plants and animals. Human populations have drastically reduced the biodiversity of different ecosystems by competing with native species for limited resources, and we also have altered their habitats (global human population growth is also due to medicine and farming techniques, reducing hunger and diseases). In this regard, it is important to highlight that the human population can also grow in an ecologically sustainable manner by taking care of the ecosystems we live in.
2. Animals (predators) are consumers, thereby they depend on lower trophic levels for their food supply. The Second Law of Thermodynamics indicates that the continual loss of energy due to metabolic activities at lower trophic levels leads to a decrease in the amount of available energy at higher trophic levels. In consequence, the population size decreases at higher levels due to the amount of energy available from one lower level to the next higher level has to decrease when it is used for metabolic activities (i.e., growth, development, etc).
3. In the food chain, the primary producers are found at the lower trophic level (e.g., plants). Primary producers are followed by consumers (e.g., herbivores), they are followed by secondary consumers (i.e., carnivores that eat herbivores), and so on. When an invasive species at higher trophic levels is introduced into a new ecosystem (in this case, human species), it is imperative to preserve the biodiversity (and consequently also the productivity) at lower trophic levels because they are fundamental for the survival of higher trophic levels (i.e., consumers).
True or false Jesse and Ray have decided to have sexual intercourse. Ray
has been with one other partner prior to Jesse. They plan on using a
condom to protect against any STls. Jesse, who has never had sex before,
does not need to worry about getting an STI since they will be using a
condom.
Answer:
False.
Explanation:
There could be rips, holes, or the condom may fail. Condoms only HELPS lower your chances for STI's/STD's.

based on the living things in the pyramid, tell me what examples would fit into these categories: primary producers, primary consumers, secondary consumers, and tertiary consumers
Answer:
Primacy Producers----- Oak tree , primary consumers------ Caterpillars , secondary consumers ------- blue jays, and tertiary consumers ----- hawk.
Explanation:
Oak tree refers to the primacy Producers in this pyramid because it produces food by using the solar energy. Caterpillars are primary consumers that feeds on the producers and also known as herbivores, blue jays are the secondary consumers that feeds on the primary consumer which is the caterpillar, and tertiary consumers are the hawk that feeds on the secondary consumer i.e. blue jays. In this way, energy flows in the food chain of an ecosystem. During this flow of energy, only 10% of energy is transferred from one trophic level to another while the remaining releases in the environment in the form of heat energy.

What happens in a warm front?
A. A warm air mass becomes a cold air mass as it moves.
B. A warm air mass catches up to a moving cold air mass, sliding
over it.
C. A cold air mass comes in under a warm air mass.
D. A warm air mass collides with a stationary cold air mass, and
slides under it.
Answer:
A warm front forms when a warm air mass pushes into a cooler air mass, shown in the image to the right (A). Warm fronts often bring stormy weather as the warm air mass at the surface rises above the cool air mass, making clouds and storms. ... As the front passes over an area, the clouds become lower, and rain is likely
Two advantages of saving money?
Answer: 1) You’ll be financially independent sooner
2) You won’t have to worry if you’re hit with any unforeseen expenses
Explanation:
1) Building up a savings nest egg can help you achieve this aim, as you could use these funds to help get on the property ladder, or to pay off student debts
2) If you’ve got savings in place, you can use some of these to cover costs, without having to turn to a credit card or personal loan to make ends meet.

You are screening three new pesticides for potential mutagenicity using the Ames test. Two his- strains resulting from either a frameshift or a transition mutation were used and produced the following results (number of revertant colonies):
Strain 1
Transition Mutant Control (no chemical) Transition Mutant + Chemical Transition Mutant + Chemical + Rat Liver Enzymes
Pesticide#1 21 180 19
Pesticide#2 18 19 17
Pesticide#3 25 265 270
Strain 2 Framshift Mutant Control (no chemical) Framshift Mutant + Chemical Framshift Mutant + Chemical + Rat Liver Enzymes
Pesticide#1 5 4 5
Pesticide#2 7 5 93
Pesticide#3 6 9 7
Required:
What type of mutations, if any, do the three pesticides induce?
Answer:
- Pesticide 1: Induces transition mutations. Rat liver enzymes convert it into a nonmutagenic product. Does not induce frameshift mutations.
- Pesticide 2: Does not induce transition mutations. Rat liver enzymes convert it into frameshift mutagen.
- Pesticide 3: Induces transition mutations. Rat liver enzymes don't have ability to convert compounds into mutagens. Does not induce frameshift mutations.
Explanation:
The Ames test is a technique widely used to evaluate the mutagenic potential of a particular chemical compound. The Ames test uses Salmonella typhimurium strains with a defective mutation that makes them unable to synthesize histidine. When the mutation is reversed, then the revertant strains can grow on a medium lacking histidine. A positive test shows that the chemical is mutagenic because its activity is associated with the reversed mutation and thereby the mutant gene regains its function. In humans, as well as in other mammals, many chemicals don't have mutagenic effects themselves but they may become converted into mutagens when are metabolized by the body. For that reason, rat liver enzymes are added to replicate the metabolic effects of the chemical compound being tested. Nowadays, current tests can express recombinant human proteins instead of rat liver enzymes, thereby enabling a better correlation between mutagenic activity and human metabolic processes.
