1. Identify one population of organisms shown in the food web, other than rabbits or mice, that would likely be affected by the introduction of snowy owls AND explain why their population would be affected.
2. State which level, a, B, or C, contains the least total available energy. Support your answer.
Answer:
The population if snakes will decline because there will be competition between snakes and snow owls. The snow owls will eat the mice, but if there's only a small population of mice. Only a few snakes will eat, other snakes will die of starvation. There will be competition between snow owls, hawks and mountain lions, but they have other sources of food, unlike snakes.
Level C contains the least amount of energy. This is because each level gets less and less energy per meal, beacuse energy is released by each organism.

Which of these statements is correct about material 1 and 2?
The half-lives of Material 1 and Material 2 are same.
The half-life of Material 2 is one-fourth of the half-life of Material 1.
The half-life of Material 2 is 5 years more than the half-life of Material 1.
The half-life of Material 1 is 5 years more than the half-life of Material 2.
Answer:
D. The half-life of Material 1 is 5 years more than the half-life of Material 2.
Explanation:
As you can see in the graphs for material 1 to get to 50% it takes 30 years. for material 2 it takes 25 years to get to 50%. Therefor the halflife of material 1 is 5 years more than material 2
Q. Why is energy required by an organism even during sleep ?
Q. Give the energy transformation that takes place in the process of photosynthesis.
Q. What is chlorophyll ?
Q. Name the various factor which affect the rate of photosynthesis.
Q. Define photolysis.
➥ Even, when an organism is asleep, various biological processes keep on occurring in its body which requires energy.
➥ During photosynthesis‚ “Solar energy is converted into chemical energy”.
➥ “Chlorophyll” is a green coloured pigment found in plants that helps in absorbing sunlight used in photosynthesis.
➥ Several factors which affect the rate of photosynthesis:
Light. Temperature. Water.CO2.➥ “Photolysis” is the process by which water is split into oxygen, which is released into the atmosphere, and hydrogen.

Explanation:
Malaria, a type of parasite, infects 500 million people each year by infecting the red blood cells of its host. The virus, HIV, that causes AIDS, reports 50,000 newly infected persons. Which statement best differentiates the pathogens, parasites and viruses?
options: Although both rely on other living organisms to survive, viruses are usually beneficial.
Although both rely on other living organisms to survive, parasites feed on the host organism.
Although both are living organisms, viruses break down dead plants and animals that other organisms use.
Although both are living organisms, parasites depend on the cells of living things to reproduce.
Answer:
The second statement clearly differentiates the pathogens best. Parasites feed on living host while viruses depend on the cells of other organisms to survive and reproduce as they cannot function outside a living host.
Although both rely on other living organisms to survive, parasites feed on the host organism. The correct option is B.
What are parasites?A parasite is an organism that lives on or in the host and obtains its food from or at the expense of the host.
Protozoa, helminths, and ectoparasites are the three main types of parasites that can cause disease in humans.
They frequently go unnoticed because they have few symptoms. However, these infections frequently result in serious illnesses such as seizures, blindness, heart failure, and even death.
A parasitic relationship takes place when one lifeform, the parasite, feeds on another organism, the host, causing harm and possibly death.
The parasite lives on or in the host's body. Tapeworms, fleas, as well as barnacles are examples of parasites.
Thus, the correct option is B.

AZT is a drug that is commonly used to fight HIV infection. The active component of AZT is a nitrogenous base that mimics thymine. Normal nucleotides CANNOT covalently bond to the thymine mimic. HIV's reverse transcriptase enzyme will use the thymine mimic instead of using thymine, whereas our DNA polymerase will not make this mistake. What is the most likely explanation for how AZT prevents HIV replication
AZT works by selectively inhibiting HIV's reverse transcriptase, the enzyme that the virus uses to make a DNA copy of its RNA. Reverse transcription is necessary for production of HIV's double-stranded DNA, which would be subsequently integrated into the genetic material of the infected cell to produce its proteins. All reverse transcriptase inhibitors are analogues of the naturally occurring deoxynucleotides needed to synthesize the viral DNA and they compete with the natural deoxynucleotides for incorporation into the growing viral DNA chain.

what is the difference between mitosis and meiosis?

Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
A plastic bottle contains 32.5 L of gas at a pressure of 45.7 kPa and
is compressed to a volume of 4.1 L. What would be the new
pressure?
Answer:
Final pressure, P2 = 362.26 kPa
Explanation:
Given the following data;
Initial volume = 32.5 Liters
Initial pressure = 45.7 kPa
Final volume = 4.1 Liters
To find the final pressure, we would use Boyle's law;
Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.
Mathematically, Boyles law is given by;
[tex] PV = K[/tex]
[tex] P_{1}V_{1} = P_{2}V_{2} [/tex]
Substituting into the equation, we have;
[tex] 45.7 * 32.5 = P_{2} * 4.1 [/tex]
[tex] 1485.25 = 4.1P_{2} [/tex]
[tex] P_{2} = \frac {1485.25}{4.1}[/tex]
[tex] P_{2} = 362.26 [/tex]
Final pressure, P2 = 362.26 kPa

3. What can the reader reasonably conclude based on the information in this passage?
A. Animals in the rain forest are strictly independent of each other.
B. Animals in the rain forest have found ways to thwart their competition and survive
C. All animals in the rain forest have the same adaptations.
D. Animals in the rain forest all need the same amount of sunlight.
i think answer is D animal in the rain forest
All animals in the rainforest have the same adaptations. Therefore, option C is correct.
What is adaptation?A physical or behavioral characteristic of an animal that enhances its ability to survive in its environment is known as an adaptation.
To put it another way, an adaptation is something a person does or has on them that makes it easier for them to locate food, water, mates, and shelter. The structural adaptations made by some plants to survive in hot, dry deserts are one illustration of this.
Animals can defend themselves against predators and extreme weather by adapting. Numerous birds may conceal themselves under long grass, while weeds, insects, and other creatures can alter their colour to blend in. Predators find it challenging to locate them in search of food as a result. Hence, option C is correct.
