human beings are also natural resources,so by me operating this computer,am utilizing myself as a natural resource.
The laptop is a device which is generally used. It is composed of electrical conductors which contains metals such as copper. Copper is a natural resource.
What are Natural resources?Natural resources are those resources which are drawn from the nature and are used with few modifications. This includes the sources of valued characteristics such as those for commercial and industrial use, aesthetic value, scientific interest, and cultural value.
Copper is a highly recyclable, non-renewable natural resource. It is present in a finite amount and cannot be regenerated once used fully. Copper is a soft and malleable metal which is used in the electrical wires and cables for its good conductivity, in the industrial machinery and construction materials for its durability, machinability, and corrosion resistance, and also the ability to be cast with high precision.

elevated the prediction using the specific experimental procedure they collected the experimental by catching mice on the beach and releasing them in lines and by catching mice from Inland releasing them on beach it wash to see if they were eaten by predators predators true or false
Answer:
True
Explanation:
The mice captured from beach would find it difficult to move in lines as it has habit to move freely in any direction. The mice will move slowly. The second mice captured from inland and released on beach would first wait before moving and it will analyze the environment. There are high chances that it nay be eaten by predator such as crab.
What is the relationship between CdKs and cyclins?
Answer:
By definition, a CDK binds a regulatory protein called a cyclin. Without cyclin, CDK has little kinase activity; only the cyclin-CDK complex is an active kinase but its activity can be typically further modulated by phosphorylation and other binding proteins, like p27.

Describe two ways in which the above law protects citizens against human trafficking
Answer:
The law in question is not included so I will include tow different laws and how they protect people from human trafficking.
1. The Victims of Trafficking and Violence Prevention Act (TVPA).
This Act made human trafficking a Federal crime while also establishing rules on how to prosecute human traffickers and getting the victims of trafficking reintegrated into society and protected. Under this Act therefore, citizens are protected because the law would act as a deterrent to a lot of would-be traffickers.
2. The Mann Act of 1910.
Under this Act, it is a crime to make promises to people such that they cross state lines and are then involved in activities they did not sign up for - this is a definition of human trafficking so this law protects citizens from that.
which organisms replicate cells by mitosis?
a. animals and bacteria
b. bacteria and plants
c. animal and plants
d. archaea and bacteria
e. archaea and plants
Answer:
d.??????????????????
Answer: C!
Explanation: eukaryotic cells may divide via either mitosis or meiosis. only sexually reproducing eukaryotes can engage in meiosis. all eukaryotes — regardless of size or number of cells — can engage in mitosis.
Having no cell nucleus, archaea do not reproduce via mitosis; rather, they procreate using a process called binary fission. So D AND E are eliminated. And so is B because that has bacteria.
SO FINAL ANSWER; mitosis happens in eukaryotes, plant and animal cells

Why are forests important for helping to control the rate of climate change?
Answer: Forests are a stabilizing force for the climate. They regulate ecosystems, protect biodiversity, play an integral part in the carbon cycle, support livelihoods, and supply goods and services that can drive sustainable growth.
Explanation:
The forest helps to maintain ecological balance, carbon cycle and rainfall.
How forest maintains ecological balance?"Ecological balance is a state of dynamic equilibrium within a community of organisms in which genetic, species and ecosystem diversity remain relatively stable, subject to gradual changes through natural succession."The forest prevent soil erosion and maintain soil fertility. It establish oxygen and carbon balance in nature.It absorbs harmful gases like carbon from environment. What is carbon cycle?"The carbon cycle is biogeochemical cycle by which carbon is exchanged among the biosphere, hydrosphere and atmosphere of the earth."Forests takes up carbon from atmosphere and gives out oxygen.Forest helps in decay, disturbance and renewal of carbon.Hence, the forest regulate rainfall, ecological balance and carbon cycle.

The division of a cell occurs once in mitosis but twice in meiosis. Two daughter cells are produced after mitosis and cytoplasmic division, while four daughter cells are produced after meiosis
Suppose that you compare the amount of food needed by four groups of lizards, each of which has a metabolic rate that is expected for its body size. There are 10 lizards weighing 10 g each, 5 lizards weighing 20 g each, 2 lizards weighing 50 g each, and a single 100-g lizard. Assuming equal digestibility, similar food, and so on, the _______ lizards need the most food.
A. 10-g
B. 20-g
C. 50-g
D. 100-g
E. All of the above need the same amount of food.
Answer:
The _10 gr__ lizards need the most food.
Explanation:
Metabolic rate: Refers to the energy used by the organism during a period of time. Small animals have higher metabolic rates than big animals to maintain energy levels. In general, small animals are more active than big animals. The amount of food needed by the animal to keep energy and body mass depends on the individual´s metabolic rate.
If small animals have a higher metabolic rate than big animals, then they need more food to maintain their energy levels. The relationship size-metabolic rate can be applied to different species -such a mouse and an elephant-or to the same species -like the one of the exposed example-.
So, in comparison, and considering their body sizes, 10 g lizards have the highest metabolic rate, meaning that they need the most food -again, considering their sizes- to keep energy and body mass constant.

Which of the following choices is an example of a non-specific barrier?
skin
white blood cells
lymphatic system
the immune system
An example of a non-specific barrier is the skin. Thus, the correct option is A.
What are non-specific barrier?Non-specific barriers are the innate, or nonspecific type of immunity of the defense system with which a person is born with. Non-specific barrier protects a person against all the antigens. Innate immunity involves the barriers which keep the harmful materials from entering the body. These barriers form the first line of defense in the immune response of an individual.
Nonspecific defense mechanisms include the skin, mucous membranes, secretions, excretions, enzymes, inflammatory responses, genetic factors, and the behavior patterns.
Skin is a physical and non-specific barrier which is covered with oily and acidic pH which ranges from 3 to 5, and the secretions from sebaceous and sweat glands, respectively.
Therefore, the correct option is A.

5) The following picture is of a single organism that has been Gram stained and is viewed under oil immersion on the compound light microscope. What is the reason for a single organism appearing like this after being Gram stained
Hi. You have not submitted any images about the microorganism the question refers to. This makes it impossible for me to answer your question. However, I will try to help you as best I can.
Gram stain is a test done to find out whether the bacteria are gram negative or gram positive. In this test, the bacteria are submitted to a certain type of dye and then are observed under a microscope. If the bacteria is gram positive, it will be purple in color. If the bacteria is gram negative, it will be red in color.
This is because after they are subjected to the violet dye, both types of bacteria absorb the color of the dye. However, before being observed under the microscope, the bacteria are washed with alcohol. Alcohol removes the dye from the gram negative bacteria, leaving them reddish. On the other hand, in gram positive bacteria, alcohol dehydrates the cell wall, compressing the pores and making the cell wall impermeable, preventing the dye from being released and, therefore, leaving the bacteria with a purple color.
