Which of the following statements about antibodies is false?(A) Antibodies are produced by different combinations of soluble proteins in the blood called complement.
(B) When antibodies bind to a bacterial cell, it may keep that cell from adhering to host cells.
(C) The specific receptors on T cells that would interact with a specific antigen are the same shape as antibodies that will interact with that antigen.
(D) By binding to antigens, antibodies mark those antigens for destruction by macrophages.
(E) By binding to an invader, antibodies attract proteins that lyse the target membrane.

Answers

Answer 1

Answer: I thought C was false because the shape will be complimentary for them to fit together not that they would be the same

Answer 2

Answer: (a) is false since antibodies are produced by body humoral immune system

Which vitamin requires intrinsic factor in order to be absorbed?A. B12
B. K
C. A
D. C

Answers

Final answer:

Vitamin B12 requires an intrinsic factor for absorption. The intrinsic factor is a protein produced in the stomach which aids in the absorption of Vitamin B12 in the small intestine. Lack of intrinsic factor can lead to vitamin B12 deficiency.

Explanation:

The vitamin that requires intrinsic factor in order to be absorbed is Vitamin B12. The intrinsic factor is a protein produced by the stomach that is necessary for the absorption of Vitamin B12 in the small intestine. Without the presence of intrinsic factor, Vitamin B12 cannot be effectively absorbed, leading to a potential vitamin B12 deficiency.

12. Which of the following correctly matches an organelle with its function?a. Nucleus: cell respiration
b. Ribosome: manufacture of lipids
c. Central vacuole: storage
d. Mitochondria: photosynthesis

Answers

The Organelle that matches its function is Central vacuole: storage

Organelles are small organs located inside the cells of plants and animals, within the cytoplasm providing specialized and specific functions in order to maintain the cell for the continuity of life.

Some of the major organelles and their specific functions includes

Nucleus - for the control of cellular activities and DNA Storage
Endoplasmic reticulum - For protein and lipid syntheses
Central vacuole- For storage of salts, minerals, nutrients, proteins.
Mitochondrion- Production of Energy through cellular respiration.
Golgi apparatus -transportation of lipids.
Ribosomes: Responsible for Protein synthesis.

Therefore, saying

Nucleus: cell respiration

Ribosome: manufacture of lipids

Mitochondria: photosynthesis are all wrong

The largest amount of groundwater is used for _______.a. drinking
b. washing
c. irrigation
d. industry

Answers

Groundwater is the water found beneath the earth's surface in spaces in soil, in cracks and rocks. These spaces are called aquifers. Groundwater serves many purposes where most of it is used in irrigation purposes. In the year 2005, 68 percent, most of the groundwater withdrawals, were used for irrigation, 19 percent was for public supply and the remaining 13 percent was used for other applications in industries.

the compound that is used for energy reserve, insulation, an to repel water is the- a)carbohydrate b)protein c)lipid d) nucleic acid

Answers

C) lipids.
LIPIDS – lipids are commonly called fats, oils, waxes, phospholipids, and steroids. Lipids contain large amounts of energy, most of which is stored in your body like an energy reserve. Lipids contain three elements: carbon, hydrogen, and oxygen (very little oxygen, however). Fats and oils are used as energy storage and insulation; waxes repel water (like the waxy cutin on leaves, and the peel of an apple); phospholipids are a big structural chemical, making up a large portion of the cell membrane; and steroids are units of structure and help control functions. Fats are made up of building blocks as well; a fat is made up of 3 fatty acids and 1 glycerol.

Answers

The correct answer is - marine organisms.

Both, the oil and the natural gas are formed on the basis of dead marine organisms. When the marine organisms were dying, they were falling in depths and onto the sea/ocean floor. The sea floor is covered with very soft sediments, and if they were not eaten by scavengers, or they have been covered with another layer of sediments, they have been relatively well preserved. As they were decomposing, the isolation, temperature, and pressure, managed to transform the dead remains of the marine organisms into oily sticky liquid that over time gained the characteristics that we see now in the oil and the natural gas.
