Answer:
See the complete question and the answer below
Explanation:
Suppose that you and a friend see brightly colored pigeons like these at a nature park. Because pigeons are usually gray and white, you both wonder where these colors came from. Suddenly, your friend says, "I have a theory. These birds must get their colors from eating food that has the same colors."Is your friend's explanation a scientific theory? Give reasons to explain your answer
The answer is no. My friend's explanation is not a scientific theory.
A scientific theory is a tested and proven phenomenon. In order for a statement to become a theory, it must have been tested through experimentation by several independent researchers and found to be true. A mere statement based on perception with little or no experimental test is just a hypothesis and not a theory.
Instead of my friend to have said, "I have a theory", he should have said, "I have a hypothesis".

Which part of a phospholipid is hydrophilic
Answer:
nonpolar fatty acid tails
The hydrophobic, or “water-fearing,” part of a phospholipid consists of its long, nonpolar fatty acid tails. The fatty acid tails can easily interact with other nonpolar molecules, but they interact poorly with water.
Answer:
The head
Explanation:
You know how phospholipids always look like they're facing outward? Well, it's because they have hydrophilic (water-loving) heads and hydrophobic (water-fearing) tails. The tails are on the inside of the phospholipid bilayer because they are hydrophobic. The heads, on the other hand, are hydrophilic, meaning that they face the outside of the phospholipid bilayer, towards the water.

do water molecules tend to push away from each other
Answer:
no the molecules tend not to push away from each other
Answer: No/False
Explanation: Water molecules stick together because of cohesion. Depending on how attracted molecules of the same substance are to one another, the substance will be less or more cohesive. Hydrogen bonds cause water to be more attracted to each other, therefore making them stick together.
You have consumed many starches which are a complex carbohydrate. Your body needs more glucose right now! What process will break down the starches into glucose?
Answer:
Digestion
Explanation:
Carbohydrates consist of starch and sugars which further break down into glucose that gives energy to the body.
Digestion of carbohydrates starts in the mouth, following the stomach and ends in the small intestine. The enzyme amylase in the process of digestion breaks down the starches into glucose.
Hence, the correct answer is "Digestion".
A young child has recently been diagnosed with Pompe disease, which causes severe muscle weakness and muscle tone. The patient lacks the enzyme alpha-glucosidase (GAA). A lack of this enzyme leads to accumulation of the carbohydrate glycogen in muscle cells. Based on your knowledge of biological macromolecules, which argument best supports why this disease is occurring? Question 13 options: Glycogen is a protein and the enzyme, alpha-glucosidase, is not breaking it down into the lipid glucose. Glycogen is a protein and the enzyme, alpha-glucosidase, is not breaking it down into the nucleic acid glycerol . Glycogen is a polysaccharide and the enzyme, alpha-glucosidase, is not breaking it down into its monomer, fatty acids and glycerol. Glycogen is a polysaccharide and the enzyme, alpha-glucosidase, is not breaking it down into the monosaccharide glucose.
Answer:
Glycogen is a polysaccharide and the enzyme, alpha-glucosidase, is not breaking it down into the monosaccharide glucose.
Explanation:
Pompe disease is an inheritable disorder that affects many parts of the body, especially the heart and other muscles.
People that are diagnosed with the disease present a defect in a gene called AAG. The enzyme alpha acid glucosidase is not present in the organism or it just does not work properly. These people have problems in processing the polysaccharide glycogen.
The AAG enzyme is located in the lysosomes, and its function is to decompose the polysaccharide glycogen (complex sugar) into the monosaccharide glucose (a simpler sugar). This last one is the source of energy of the organism.
The unproperly functioning of the enzyme causes the accumulation of glycogen in lysosomes of the macrophages.

Suzie Q wants to know how different colors of light effect the growth of plants. She
believes that plants can survive the best in white light. She buys 5 ferns of the same
species, which are all approximately the same age and height. She places one in
white light, one in blue light, one in green light, one in red light and one in the
closet. All of the ferns are planted in Miracle-Grow and given 20 mL of water once a
day for 2 weeks. After the two weeks, Suzie observes the plants and measurements.
4. What measurements could Suzy make to determine how different colors of light
affect the growth of plants?
Answer:
Suzie can measure the HEIGHTS of the plants in metres (m) or centimeters (cm)
Explanation:
According to this question, Suzie Q wants to know how different colors of light effect the growth of plants. She sets up the experiment by exposing 5 ferns of the same species to different colors of light (white, blue, green, red).
After ensuring that some variables called constants like same 20 mL of water, same fertilizer (miracle-grow) etc are the same for all ferns, She then measures the growth of each fern placed under different colors of light.
The independent variable in this experiment is the different colors of light while the dependent variable is the growth of the plants. This question is asking for how Suzie could measure the dependent variable (growth). Suzie can measure the growth of the ferns placed under different colors of light by RECORDING THE HEIGHTS OF EACH FERN IN cm or m.
At what part of the growing process is creativity more important? When is consistency more important?
Answer:
Creativity is most important . It develop in every stage of life. I t could be consistent when it get stable.
Explanation:
We could not count consistency as everything but it is counted for a lot. Creativity is more important at every stage when you grow up . The creative mind play role as a machinery. Consistent means you are not doing anything, you are constant.
As we can say that process is more important. When you are consistently working you are learning something new. So that when you are thinking about something too much then you wont do it. Creativity is rooted in the culture of an individual. Creativity is bounded with culture. It consists the dynamic thought. Creativity can no any exception.

After learning about Addie, think about infections that you or family members had. Have you or a family member ever taken antibiotics for an infection/skin infection/rash/ear infection/chest cold? What happened?
Answer:
Yes, I have taken antibiotics for an infection or infectious disease.
Antibiotics are specialized drugs to generate bacteriostatic or bactericidal effects in BACTERIA.
These, like all drugs, have adverse effects that may be worse or less serious according to the potency of the drug.
Each antibiotic has different spectra of bacteria, that is, they can affect more or less bacterial species.
Explanation:
That antibiotics are bacteriostatic implies that they stop bacterial metabolism, and that they are bactericidal indicate that they eliminate or kill the bacteria, each antibiotic is special for each bacterium.
In infectious diseases or infections it is important to know what bacteria we are facing, doing a culture to detect the species and also an antibiogram that warns us to which antibiotic this bacteria is resistant, if it is.
In this way, antibiotic therapy will be effective since the bacteria will be within the spectrum of the chosen drug and will not present resistance, these diagnostic methods are necessary because there are bacteria with beta-lactamases as a resistance factor, that is, resistant to beta lactams, it is for That is why an inhibitor of these enzymes was launched so that these bacteria cannot destroy the drug and have efficacy at the end of the day, this beta-tetramase inhibitor is clavulanic acid, which together with penicillin were the great discovery of pharmacology.

Numerous colleges and universities around the world, including quite a few in the United States and Canada, offer degree programs in environmental science, studies, policy, and management. Many students who later transferred to graduate school for an environmental degree may have started off in a different major.
what is Environmental science?
In order to study the environment and find solutions to environmental issues, environmental science is an interdisciplinary academic field that combines physics, biology, and geography (including ecology, chemistry, plant science, zoology, mineralogy, oceanography, limnology, soil science, geology and physical geography, and atmospheric science). During the Age of Enlightenment, environmental science developed from the disciplines of natural history and medicine. [1] Today, it offers an interdisciplinary, integrated, quantitative approach to the study of environmental systems. [2]
More social sciences are incorporated into environmental studies in order to better understand human interactions, viewpoints, and environmental policy. Engineering for increasing environmental quality in all areas is the emphasis of environmental design
Environmental scientists work to comprehend the physical, chemical, biological, and geological processes that occur on Earth and then use that understanding to comprehend how problems like alternative energy sources, pollution control and mitigation, resource management, and the effects of global warming and climate change affect and influence these processes and natural systems. Physical, chemical, and biological processes almost invariably interact with one another to create environmental challenges. Environmental scientists analyze environmental issues from a systems perspective. The capacity to relate spatial and temporal correlations and quantitative analysis are essential skills for environmental scientists. The need for a multidisciplinary approach to analyze complex environmental problems, the arrival of substantive environmental laws requiring specific environmental investigation protocols, and the growing public awareness of the need for action in addressing environmental problems were the driving forces behind the emergence of environmental science as a substantive, active field of scientific investigation in the 1960s and 1970s. The release of Rachel Carson's seminal environmental work Silent Spring[3] and the public attention given to significant environmental problems like the Santa Barbara oil spill in 1969 and Cleveland, Ohio's Cuyahoga River "catching fire" (also in 1969) all contributed to the emergence of this new field of study and raised awareness of environmental problems.

Enzymes are proteins that have a three-dimensional shape that is specific to a particular substrate. Environmental conditions can change the shape of the protein. What is the most likely result if the shape of the enzyme changes?
Answer:
The enzyme will no longer be able to catalyze the reaction with the substrate.
Explanation:
The enzyme will no longer be able to catalyze the reaction with the substrate if the shape of enzyme changes. The correct option is B.
What is enzyme-substrate reaction?A substrate needs to enter the enzyme's active site. This results in the formation of the enzyme-substrate complex.
The reaction then accomplished, transforming the substrate into products and forming an enzyme products complex. The products after which end up leaving the enzyme's active site.
When an enzyme is bonded to its substrate, an enzyme-substrate complex is formed.
Enzymes encourage chemical reactions by bringing substrates together in the best possible orientation, thereby providing an ideal chemical environment for the reaction to take place.
Enzymes change their shape in order to bind to their substrates. The process by which enzymes change shape is known as induced fit.
Since enzymes in the given scenario is changing their conformation, it will lead to non binding of the substrate.
Thus, the correct option is B.
