Answer:
D. Doughnut Economic Model
Explanation:
The "Doughnut Economic Model" is focused on the benefits that people can get in its economy rather than its growth. This situation is also known as the "circular economy," which deems thriving as more important than growing. The doughnut is represented by different things. The middle hole refers to the poor people in the society. The inner ring refers to the things we need in order to thrive in life while the dough refers the the area where people meet their needs. All of these interact within a circle, thus the term circular economy.

Why is there a border between light and dark on the moon
Answer:
As the Moon orbits around the Earth, we are able to see more or less of the half that is illuminated. ... There is a border between light and dark on the moon because the sun illuminates the half of the moon that is facing it. Leaving the other half dark.
Explanation:
Hope this helps!
The moon is the earth's only natural satellite and it gets its light from the sun. The moon changes its phases from a new moon to a full moon.
The terminator is the dividing line that is found between the moon's lighter and darker sides. It is sometimes known as the twilight zone. It can be seen during the rising and setting of the sun. The line is there so as to indicate the difference between night and day. The sun can illuminate only that part that is facing it. As the moon also rotates around the earth only that side is visible.Hence the sunlight travels in a straight path and can't reach the other side.

characteristics of contaminated water
Contaminated water is a type of water that is harmful to human beings due to the presence of harmful substances, pollutants, or impurities that make the water unsafe for drinking or other household uses. The characteristics of contaminated water can be identified through various indicators, which can either be physical, biological or chemical.
Physical indicators are visible and may include color, taste, and odor, while biological indicators are not visible and may include bacteria, viruses, and protozoa. Chemical indicators may include heavy metals, pesticides, and organic compounds, among others.
Physical Characteristics: Physical characteristics of contaminated water include cloudy or turbid appearance, unusual taste or odor, or discoloration of the water. The color may range from yellow to brown, blue to green, or even black.
Biological Characteristics: Biological characteristics of contaminated water include the presence of bacteria, viruses, or protozoa. These microorganisms can cause diseases such as diarrhea, typhoid, cholera, and dysentery.
Chemical Characteristics: Chemical characteristics of contaminated water include the presence of heavy metals such as lead, arsenic, or cadmium. Pesticides and fertilizers can also contaminate water and affect human health. Organic compounds like benzene and toluene can also be present in contaminated water, which can lead to health problems such as cancer and nerve damage.
Therefore, it is important to test water sources regularly to identify and monitor any contaminants that may be present. This can help prevent health problems associated with the use of contaminated water.

Is it a scientific theory or a scientific law that the characteristics of living things change over time?
Answer:
Scientific Theory
Explanation:
The statement "the characteristics of living things change over time" refers to the concept of biological evolution, which is widely accepted as a scientific theory in the field of biology. In scientific terms, a theory is a well-substantiated explanation of a natural phenomenon that is supported by extensive evidence, experimentation, and scientific consensus. The theory of evolution, proposed by Charles Darwin and further developed over time, provides a comprehensive explanation for the diversity and change in the characteristics of living organisms. It is supported by a vast body of evidence from various scientific disciplines, including genetics, paleontology, comparative anatomy, and molecular biology.
In contrast, scientific laws describe observable patterns or regularities in nature that are often expressed as mathematical equations or principles. Laws, such as Newton's laws of motion or the laws of thermodynamics, describe specific relationships or behaviors in the physical world.
Therefore, the statement about the characteristics of living things changing over time aligns with the theory of evolution, rather than being described by a scientific law.

(10Base your answer(s) to the following question(s) on the information belowand on your knowledge of biology.The hedgehog, a small mammal native to Africa and Europe, has beenintroduced to the United States as an exotic pet species. Scientists havefound that hedgehogs can transfer pathogens to humans and domesticanimals. Foot-and-mouth viruses, Salmonella, and certain fungi are knownpathogens carried by hedgehogs. As more and more of these exotic animalsare brought into this country, the risk of infection increases in the humanpopulation.State one way the human immune system might respond to an invading pathogenassociated with handling a hedgehog.
One way that the human immune system responds to an invading pathogen associated with handling a hedgehog is by the white blood cell will engulf and destroy pathogens.
We can associate this response to a humoral response in which our immune system will create an antibody and this antigen-antibody complex will detect a foreign body or pathogen and they will destroy it through phagocytosis.
A group of researchers transformed E. coli to express
dsRNA that matched a transcription factor, eaf-1. They
then fed these E. coli to C. elegans worms. When the
researchers examined the C. elegans, they found that
they had fewer offspring and were smaller individuals,
with similar characteristics to C. elegans in which eaf-1
had been knocked out.
The students suggested several hypotheses based on
these observations about how RNAi worked:
1. The dsRNA inhibited gene transcription.
2. The dsRNA inhibited mRNA processing.
3. The dsRNA inhibited translation of mRNA into protein.
4. The dsRNA inhibited protein folding.
Mark this and return
The researchers then performed a series of experiments
to determine which hypothesis was correct. The C.
elegans were found to be transcribing eaf-1 into mRNA,
but not producing eaf-1 protein. When the students
directly injected C. elegans with dsRNA and tracked
tagged mRNA, they found the mature mRNA was
degraded in the cytoplasm, and ribosomes were not
binding to it. Which hypothesis is supported by these
observations?
The hypothesis that is supported by these observations is that the dsRNA inhibited the translation of mRNA into protein (third option).
What does the experiment reveal about dsRNA?In this experiment, the C. elegans worms were transcribing eaf-1 into mRNA but not producing the eaf-1 protein. This phenomenon shows that dsRNA inhibited the translation of mRNA into protein related to the action of E. coli on the worms.
This also explains why the worms affected by this bacteria had fewer offspring and the offspring were smaller.

Describe what must happen for fertilisation to take place in humans.
In the process of sexual reproduction, mating of male gamete and female gamete is required for the fertilization to take place in humans.
A gamete is an animal or plant reproductive cell. Male gametes in animals are known as sperm, while female gametes are known as ova or egg cells.
Fertilization is the process in which a woman's egg combines with a man's sperm to form an embryo.
Usually, the fallopian tube that connects an ovary to the uterus is where fertilization occurs. An embryo begins to develop if the fertilized egg successfully passes through the fallopian tube and implants in the uterus.

Which of the following statements best describes the effects that depressants have on the body due to its effects on the central nervous system?
Depressants slow down the activity of the central nervous system, resulting in relaxation, drowsiness, and impaired judgment, coordination, and reaction time and effect the central nervous system.
The central nervous system (CNS) is the part of the nervous system that includes the brain and spinal cord. It is responsible for integrating sensory information from the body and the environment, and controlling behavior and motor responses. It consists of neurons, glial cells, and specialized receptors. The neurons process information and transmit signals to and from other parts of the body. The glial cells provide structural and metabolic support. The specialized receptors detect and transduce information from the environment, such as light and sound. The CNS is responsible for higher-order functions such as thought, emotion, learning, and memory. It is also responsible for controlling unconscious processes such as respiration, digestion, and other involuntary functions

"Histology Lab Tissues are groups of cells with similar shape and function. The purpose of this lab is to give you experience looking at and identifying tissue slides taken from areas all over the body. Epithelium 1. What is the primary purpose of all epithelial tissue? 2. Besides skin, give two examples of different body "surfaces" that are exposed to the outside environment and would need a lining of epithelium. 3. Label the following as squamous, cuboidal, or columnar."
Answer:
1. The primary purpose of all epithelial tissue is to cover the different body surfaces, this includes cavities that are not in contact with the exterior and parts of the body that are in contact with the exterior.
2. Tongue and esophagus.
3. The images with the types of epithelium are attached.
Explanation:
The main purpose of epithelial tissue is to cover all the surfaces of our body. These are the cavities, and the parts that are in contact with the exterior. They create barriers that protect the body, secrete, absorb substances, allow the passage of specific elements, and stop the entrance of others. The functions vary according to where the tissue is in the body.
The tongue, as it is in contact with the exterior and with the food that enters our mouth, it has a stratified squamous epithelium. The thickness of this epithelium protects it against the different things that can damage or enter through it.
The esophagus has a nonkeratinized stratified squamous epithelium that protects the esophagus from the damage, that food or antigens may cause.
Squamous epitheliums have cells with a not specific shape that has their nucleus in the center.
Cuboidal epithelial have lined cells with a cuboidal shape.
Columnar epithelial have lined cells with a rectangular shape, and their nucleus is near the basal region.
