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.
Why are some birds incapable of flight?
Answer:
Ostriches, emus, cassowaries, rheas, and kiwis can't fly. Unlike most birds, their flat breastbones lack the keel that anchors the strong pectoral muscles required for flight. Their puny wings can't possibly lift their heavy bodies off the ground.
Explanation:
Answer:
cuz they're fat and their wings are small
Explanation:
their flat breastbones lack the keel that anchors the strong pectoral muscles required for flight
they lost the ability to fly through evolution because flying was no longer needed

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.

In pea plants, purple flowers are dominant to white flowers. Suppose two heterozygous purple-flowered plants (Tt) are crossed. What percentage of offspring will also have purple flowers?
Answer:
75%
Explanation:
This question involves a single gene coding for flower color in pea plants. The allele for purple flowers (T) is dominant over the allele for white flowers (t).
According to the question, two heterozygous purple-flowered plants (Tt) are crossed i.e. Tt × Tt. The following gametes will be produced by each parent; T and t. Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
TT, Tt, Tt, and tt.
Since purple allele (T) is dominant, offsprings TT, Tt, and Tt will be phenotypically purple-flowered. Hence, ¾ × 100 = 75% of offsprings will have purple flowers.

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).

Answer:
Protista and Fungi
Explanation:
Protista and Fungi includes more than one body type. So, the correct option is A.
What is Fungi and Protista kingdom?Simple eukaryotic organisms known as protozoa are not classified as either plants, animals, or fungus. Although they are often unicellular, protozoa may also be found as just a colony of cells. The majority of protists are parasites or live in wet terrestrial habitats. A eukaryotic protist named as Euglena.
Eukaryotic organisms known as fungi which include yeasts, moulds, and mushrooms as well as other microorganisms. These organisms fall under the category of fungi. The creatures that make up the Kingdom Fungi are pervasive and have a cell wall. They fall under the category of heterotrophs among living things. Protista and Fungi includes more than one body type.
Therefore, the correct option is A.

A Korean male dies at 1:52 pm. When his body temperature
was taken, 12 hours later, it was 86.4" F. Which of the
following BEST explains why this temperature would be
skewed?
1. Ambient temperatures must be higher than
room temperature
1. Ambient temperatures must be lower than
room temperature
K. The victim must have died unclothed
L. The investigator must have been careless in
their calculations
The temperature is skewed because ambient temperatures must be lower than room temperature. Therefore, option B is correct.
Why the temperature is skewed?The body temperature of a deceased individual normally drops after death due to the cessation of metabolic processes. This process is known as postmortem cooling or algor mortis. The rate of postmortem cooling depends on several factors, including the ambient temperature of the environment in which the body is located.
In this case, the body temperature was taken 12 hours after the individual's death, and the recorded temperature of 86.4°F suggests that the ambient temperature of the environment was lower than room temperature.
This is because the normal room temperature for most indoor settings is around 68-72°F, and a body temperature of 86.4°F after 12 hours of postmortem cooling is abnormally high. Thus, option B is correct.

What is a species that has been studied in great detail and is used to understand specific phenomena in biology? (ther are no answer choices btw)
PLEASE HELP!!!
What species that has been studied in great detail and is used to understand specific phenomena in biology?
Answer:
Species that has been studied in great detail and is used to understand specific phenomena in biology are Model organism .
Explanation:
MODEL ORGANISM - A model organism (often abbreviated to model) is a non-human species that has been extensively studied in order to better understand specific biological processes, in the hope that observations made in the model organism can lead to new understanding of the workings of other organisms. When human experimentation is either impossible or immoral, model organisms are commonly used to study human disease. The shared descent of all living species, as well as the survival of metabolic and developmental processes and genetic material during evolution, make this strategy possible.
Although studying model organisms can be beneficial, caution should be exercised when extrapolating results from one organism to another.
Viruses, as well as model organisms from all three realms of life, are included. Escherichia coli (E. coli) is the most widely studied prokaryotic model organism, having been studied for more than 60 years.
It's a common gram-negative gut bacterium that can be easily and cheaply grown and cultured in a laboratory environment. It is the most commonly used organism in molecular genetics, as well as an important species in biotechnology and microbiology, where it has acted as the host organism for most recombinant DNA research.
Hence , the answer is model organism .
