I have compared a cell to an amusement park for the assignment what part of an amusement park is similar to a mitochondria (breaks down food to make energy for cell)
you could do a boat ride! look up a picture of the cell n like make it into a boat ride. they could also be the little trains that travel around the park. hope this helped!
Answer:
The plasma membrane is like a gate and is a phospholid bilayer that surrounds the cell. The gate is much like the plasma membrane in that it selects who can enter an amusement park with a ticket. This is like the entrance to a park. The nucleus is like the information booth that contains all of the blueprints for making necessary points. At an amusement park, the information booth, much like the nucleus of a cell, provides all information and maps for where to go and what to find. The lysosome is like a recycling bin that digests excess or worn out organelles in cells. They contain digestive enzymes. In an amusement park, without trash cans, excess food and waste would have no where to be thrown away. By recycling waste, it is put through a process much like the digestive enzymes. The ribosomes are like food stands, that make proteins according to the instructions given by the DNA. Food stands in an amusement park provide nutrients and refreshments for the guests. This is much like the process of ribosomes. The rough endoplasmic reticulum are like buses. It is a series of high folded membranes that provide transport system between the nucleus and cytoplasm. In an amusement park, transportation is needed to provide guests with fast access to areas of the park. Buses provide the quickest transportation for guests.

1. Where does the body get glucose molecules?
2. Where does the body get amino acids?
3. Where does the body get oxygen?
4. What do you think could happen if the human body doesn’t take in one or all of these molecules? Why do you think this?
Answer:
1. Glucose molecules come from the food we eat. we digest the food, then it mixes with acid/enzymes in the stomach. then the food breaks down and becomes glucose (blood sugar).
2. the best place to get amino acids is through protein-rich foods. when you eat protein, it gets broken down into amino acids, which are used for building muscle and "regulating immune function"
3. enters through the alveoli. it exchanges with older air in the lungs.
4. A. glucose- cause low blood sugar, causing problems in your nervous system
B- amino acids-decreased immunity, fertility issues, slowed growth (in children), digestion problems, and depression.
C- oxygen- basically suffocation, which leads to death

Answer:
A serum containing anti-A antibodies is mixed with some of the blood. ... For instance, if an individual's blood sample is agglutinated by the anti-A antibody, but not the anti-B antibody, it means that the A antigen is present but not the B antigen. Therefore, the blood type is A.

1. Where does the body get glucose molecules?
2. Where does the body get amino acids?
3. Where does the body get oxygen?
4. What do you think could happen if the human body doesn’t take in one or all of these molecules? Why do you think this?
Answer:
1.This energy comes from the food we eat. Our bodies digest the food we eat by mixing it with fluids (acids and enzymes) in the stomach. When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose.
2.Humans can produce 10 of the 20 amino acids. The others must be supplied in the food. Failure to obtain enough of even 1 of the 10 essential amino acids, those that we cannot make, results in degradation of the body's proteins—muscle and so forth—to obtain the one amino acid that is needed.
3.The oxygen enters the bloodstream from the alveoli, tiny sacs in the lungs where gas exchange takes place.
4.Generally speaking, we need to consume around 0.65g of protein per kg of body weight each day. However, this depends on physical activity and our general health.People who are found to have low protein in their body (hypoproteinaemia) are either not taking enough in through their diet, or are unable to absorb it. Malabsorption of food is often found in patients with gut problems, and nutritional deficiencies are often seen in chronic bowel disorders.

True or false: The pressure of gas cannot vary directly with temperature
Answer:
i believe its true
Answer:
true
Explanation:
The pressure of a given amount of gas is directly proportional to its absolute temperature, provided that the volume does not change (Amontons's law). The volume of a given gas sample is directly proportional to its absolute temperature at constant pressure
What are the pros and cons of GMO's
Answer: A pro '' Easier to ship and resistance to pest.'' A con '' Environmental risk and only rich countries can afford it.''
Explanation:
Advantages of GMO foods include added nutrients, fewer pesticides, and cheaper prices and disadvantages of GMO foods can be allergic reactions or increased antibiotic resistance.
What do you mean by genetically modified organisms?Genetically modified (GM) foods are foods derived from organisms whose genetic material (DNA) has been modified in a way that does not occur naturally, e.g. through the introduction of a gene from a different organism.
Most of the GMO crops grown today were developed to help farmers prevent crop and food loss and control weeds. The three most common traits found in GMO crops are: Resistance to certain damaging insects.
Potential health risks to humans include the possibility of exposure to new allergens in genetically modified foods, as well as the transfer of antibiotic-resistant genes to gut flora.

What determines whether a metamorphic rock is foliated or non-foliated?
Answer:
Foliated metamorphic rocks such as gneiss, phyllite, schist, and slate have a layered or banded appearance that is produced by exposure to heat and directed pressure. Non-foliated metamorphic rocks such as hornfels, marble, quartzite, and novaculite do not have a layered or banded appearance.
Explanation:
Answer: Foliated rocks have layers you can see, non foliated rocks don't have layers.

Answer:
herbivores
Explanation:
Animals that eat only plants are called herbivores (or primary consumers). Animals that eat other animals are called carnivores. Carnivores that eat herbivores are called secondary consumers, and carnivores that eat other carnivores are called tertiary consumers.
Herbivores. Animals that eat only plants are called herbivores (or primary consumers). Animals that eat other animals are called carnivores.
What are Primary consumer?Carnivores that eat herbivores are called secondary consumers, and carnivores that eat other carnivores are called tertiary consumers.
An alligator (Alligator mississippiensis) snoozes on the bank of a slow-moving water channel on a sawgrass prairie in the Florida Everglades. In the shallows, a great egret (Ardea alba) is pursuing fish. An aster leaf is being chewed by a grasshopper (Brachystola magna).
Every ecosystem has living things that work together to distribute energy in predictable ways. A trophic pyramid, as it is known among scientists, can depict these interconnections.
Therefore, Herbivores. Animals that eat only plants are called herbivores (or primary consumers). Animals that eat other animals are called carnivores.

Explain when each of the following process occur in the rock cycle- Compaction and Cementation, Melting; Cooling and hardening, Heat, pressure, weathering and Erosion.
Answer:
The rock cycle shows how the earth's rocks are changed again and again. The rocks can be changed at times to another type of rock. The rock cycle can begin anywhere in the cycle. Here’s how it works…
• Igneous rocks start as magma. Technically, ALL rocks start as magma.
• The magma (molten rock under the surface) and lava (molten rock on the surface) hardens into igneous rock.
• The igneous rock then breaks apart over time through the process of weathering.
• These bits of broken rock are washed away by rains and deposited in a river.
• These pieces of igneous rocks are cemented together with other bits of rock and form a sedimentary rock called conglomerate.
• Over time sedimentary rocks can be buried by earthquakes or other geologic processes.
• Being buried deep under the surface in areas of high temperatures and pressures or coming in contact with magma can cause these sedimentary rocks to change to metamorphic rocks.
• Metamorphic, sedimentary or igneous rocks can be remelted to form magma, beginning at the beginning
again.

THis is science.
Answer:
5. The main function of the smooth ER is the synthesis of lipids, steroids, and carbohydrates. It is also involved in the detoxification of drugs and toxins. The rough ER is mainly involved in protein synthesis. It is lined with ribosomes. The rough ER and the ribosomes on it work to make and ship proteins to other parts of the cell.
6. The nucleus can only be found within eukaryotic cells.
7. Plant cells are green because of chlorophyll. Chlorophyll is used in photosynthesis and it does not absorb the green wavelengths of white light, rather it reflects it, giving plants their green color.
8. The vacuole stores materials like water, nutrients, and waste for the cell. In plant cells, vacuoles are large and mainly store water. They are so large they even provide some structure for the cell. This type of vacuole is called the central vacuole. Vacuoles in animal cells are smaller and there are typically more than one.
9. The purpose of a cell wall is for added structure and protection of plant cells.
10. A chloroplast is an organelle only found in plant cells. It is where photosynthesis takes place. Essentially, it makes food for the plant.
