Match each blood part with the correct description.
1. prevents body from losing blood after injury
plasma
2. fights off disease in the body
red blood cells
3. carries oxygen around the body
white blood cells
4. is made of 90% water
platelets
The matching of each blood part with the correct description is as follows:
Prevents body from losing blood after injury: PlateletsFights off disease in the body: White blood cells. Carries oxygen around the body: Red blood cells. It is made of 90% water: Plasma. What are the functions of the blood?The functions of the blood are as follows:
It transports oxygen and other required nutrients to the lungs and tissues.It significantly constructs blood clots in order to prevent excess blood loss during injury.Blood while flowing carries cells and proteins known as antibodies which fight against infections.It regulates body temperature.The flowing blood is a very complex mechanism. This is because it prevents the mixing of carbon dioxide rich-blood which we get from the cells and tissues to the oxygen-rich blood which we get from the heart and transport to the lungs.
Each component of the blood plays an active role in order to function properly and increases the chances of survival by the elimination of infections.
Therefore, the matching of each blood part with the correct description is well-described above.

When and how do body systems work together?
Answer:
Just as the organs in an organ system work together to accomplish their task, so the different organ systems also cooperate to keep the body running. For example, the respiratory system and the circulatory system work closely together to deliver oxygen to cells and to get rid of the carbon dioxide the cells produce.

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.

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.

Giant anteaters live in Central and South America. As their name suggests, they eat ants and termites. First, an anteater tears open insect nests with its long claws. Then, it extends its extremely long, sticky tongue into the nest to catch its prey. One anteater eats 35,000 ants and termites in a day.
Look at the table showing the Linnaean levels of classification for the giant anteater. Then create the scientific name for this species. Choose the best option for each part of the name. (What is its scientific name?)

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.

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.
