Answer:
Five (5) buses
Explanation:
A total of five (5) buses would be needed for the trip.
From the illustration:
Total number of students = 100
Number of students that each bus can contain = 20
In order to calculate the total number of buses that would be needed for the trip, the total number of students would be divided by the number of students each bus can contain.
Hence, number of buses needed = 100/20 = 20 buses.

This question is asking to identify the directional relationship between the following organs. They are explained below.
Explanation:
1. The heart is MEDIAL to the lungs because it is located towards the middle in relation to the right and left lungs.
2. The knee is DISTAL to the hip because it is farther away from the point of attachment of the hip joint.
3. The wrist is PROXIMAL to the hand because the wrist is closest to the point of origin of the hand.
4. The mouth is INFERIOR to the nose because it is lower in direction to the nose.
5. The thorax is SUPERIOR to the abdomen because it is located above the abdomen.
6. The thumb is DISTAL to the ring finger because it is far away from the ring finger.
7. The sternum is ANTERIOR to the heart because it lies in front of the heart
8. The skull is SUPERFICIAL to the scalp because it is close to the body surface.
9. The ears are LATERAL to the nose because it is towards the middle line of the nose
10. Dorsal refers to the BACK of the human body, while ventral refers to the FRONT of the human body.
The heart is medial to the lungs. 1- medial, 2- distal, 3- proximal, 4- Inferior, 5- superior, 6- distal, 7- anterior, 8- superficial, 9- lateral, 10- back, and 11- front.
In the thoracic cavity, the heart is located in the middle of two lungs and before a vertebral column. However, it is located behind the breastbone plate, i.e. the sternum.
The thorax, also known as the chest, is the upper part of the trunk between the neck and the abdomen. The thorax is made up of several parts: the thoracic wall and several cavities.
The sternum is a bone located in the anterior middle line of the thoracic region of the body. It forms the base of the rib cage. The sternum is the anterior-most part of the body.
The sternum protects the thoracic tissues from injury. It also serves as the bony attachment point for various muscles.

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.

If two events are correlated, what must be true? (1 point)
O Both events have the same result.
O Both events have the same cause.
O The events tend to happen together.
O One event caused the other.
Answer:
Both events have the same cause.
Explanation:
Correlation in statistics refers to the measure of the relationship between two variables. Simply put, two variables are said to be correlated if a mutual relationship exists between them. This means that if two events correlates, a relationship in which, both events have the same cause, exists between them.
Correlation can be positive or negative depending on whether the increase of one event causes the other to increase (positive) i.e. they both move in a similar direction or the increase of one event causes the declination of the other (negative) i.e. they move in opposite directions.

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".

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.

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.
