Answer the following question given this paragraph: According to the cell theory , all living things are made up of cells, which is the structural unit of living organisms, and living cells always come from other living cells. In fact, each living thing begins life as a single cell. Some living things, such as bacteria, remain single-celled. Other living things, including plants and animals, grow and develop into many cells. Your own body is made up of an amazing 100 trillion cells! But even youlike all other living thingsbegan life as a single cell. Q: What is your body made up of? Choices: - skin - millions of elements - energy - trillions of cells A:
trillions of cells

Answer the following question given this paragraph: Imagine walking in the forest in Figure below . The towering trees have been growing here for hundreds of years. It may seem as though the forest has been there forever. But no ecosystem is truly static. The numbers and types of species in most ecosystems change to some degree through time. This is called ecological succession. Important cases of ecological succession are primary succession and secondary succession. Q: The numbers and types of species in most ecosystems change to some degree through time and this is called? Choices: - physiological succession - continuous succession - environmental succession - ecological succession A:
(Answer)
ecological succession
Ques: Answer the following question given this paragraph: Work is defined differently in physics than in everyday language. In physics, work means the use of force to move an object. The teens who are playing basketball in the picture above are using force to move their bodies and the basketball, so they are doing work. The teen who is studying isn't moving anything, so she isn't doing work. Not all force that is used to move an object does work. For work to be done, the force must be applied in the same direction that the object moves. If a force is applied in a different direction than the object moves, no work is done. The Figure below illustrates this point. Q: In physics, work means the use of what to move an object? Choices: - mass - energy - leverage - force A:
Ans: force
(Q).
Answer the following question given this paragraph: Hemophilia is a group of diseases in which blood does not clot normally. Factors in blood are involved in clotting. When you bleed, your body begins a coagulation cascade of reactions, involving special proteins known as coagulation factors, to stop that bleeding. When one or more of these clotting factors are missing, there is a higher chance of having dificulties stoping the bleeding. Hemophiliacs lacking the normal Factor VIII are said to have Hemophilia A (or Factor VIII deficiency), the most common form. Hemophilia is a genetic disease, passed down through family. It is linked to the X-chromosome, so it mostly affects males. F8 is the gene for the Factor VIII protein. Mutations in the F8 gene lead to the production of an abnormal version of coagulation factor VIII, or reduce the amount of the protein. The altered or missing protein cannot participate effectively in the blood clotting process. Q: What is the term for diseases in which blood does not clot normally? Choices: - arthritis - diabetes - lymphoma - hemophilia A:
(A).
hemophilia
Ques:Answer the following question given this paragraph: Skin is made up of two layers, the epidermis and the dermis. Q: What are the two layers of the skin? Choices: - dermis and epithelial - sebaceous and salivary - epithelial and endometrial - epidermis and dermis A:

Ans:epidermis and dermis
Answer the following question given this paragraph: There are four main ways that molecules can pass through a phospholipid membrane. The first way requires no energy input by the cell and is called simple diffusion. This type of transport includes passive diffusion and osmosis. No assistance by a transport is necessary in simple diffusion. Facilitated diffusion, does involve the assistance of transport proteins. The third way, called active transport , requires that the cell uses energy to pull in or pump out certain molecules and ions. Active transport involves proteins known as pumps. The fourth way is through vesicle transport , in which large molecules are moved across the membrane in bubble-like sacks that are made from pieces of the membrane. Vesicular transport includes exocytosis and endocytosis. Q: Vesicular transport includes exocytosis and what? Choices: - phagocytosis - metastasis - meiosis - endocytosis A:
endocytosis
