Answer:
Biosphere
Explanation:
The biosphere is the part of the earth that supports life forms. It includes hydrosphere, atmosphere, and lithosphere. Various ecosystems, aquatic or terrestrial, are present in the biosphere. Biotic and abiotic components of a geographical region that interact with each other together make an ecosystem.
The biotic component of an ecosystem includes all the organisms present in it. Organisms may be unicellular or multicellular. All the organisms are made up of one or more cells. Cells are made up of various biomolecules that interact and enable cells to perform the life processes.
Answer:
Which type(s) of cell division reduce(s) the chromosome number by half?
Meiosis l
Which type(s) of cell division can be classified as reductional?
Meiosis I
Which type(s) of cell division can be classified as equational?
Mitosis and Meiosis II
Explanation:
Meiosis is a type of cell division which occurs in the germ or reproductive cells to produce gametes. It is completed in the two stages, meiosis I and meiosis II. The cells which are going to divide by meiosis are diploid having two sets of chromosomes. Meiosis I is the first stage of the meiosis. At the end of meiosis I two daughter cells are formed having only 1 set of chromosomes and chromosome numbers are reduced to half. Thus, meiosis I is a reductional division.
Mitosis and meiosis II is the equational division as after division chromosome number remains the same as in the parent.
B is the correct answer due to the fact that applied sciences means adding to already developed technology there scientist are creating another drug to cure human diseases by mixing different elements through the process of an experiment
Soil nutrients are important to photosynthesis because they <u>help with chlorophyll </u><u>formation</u><u>.</u>
Answer:
11. b.
Explanation:
Photosynthesis stores energy in carbohydrates, cellular respiration releases energy from carbohydrates.
Glucose, C₆H₁₂O₆, is a carbohydrate.
Write out the equations:
<u>Photosynthesis</u>
carbon dioxide + water + light energy => oxygen + glucose/sugar
CO₂ + H₂O + light => O₂ + C₆H₁₂O₆
The carbohydrate is stored in the plant until it needs it, like to perform cellular respiration.
<u>Cellular Respiration</u>
oxygen + glucose/sugar => carbon dioxide + water + ATP energy
O₂ + C₆H₁₂O₆ => CO₂ + H₂O + ATP
The carbohydrate is used to make energy. Energy is released from carbohydrates.
Glucose, C₆H₁₂O₆, is a carbohydrate.
Fault in other options:
a. Photosynthesis and cellular respiration both occur in plants. Plants have mitochondria for cellular respiration.
c. Photosynthesis uses carbon dioxide and cellular respiration releases carbon dioxide.
d. Photosynthesis uses carbon dioxide, cellular respiration uses oxygen.
