Answer:
1 : 5
Explanation:
Ratio is used to show the relationship between two amounts. It tells how many one value is contained within another value. Ratio can be used to compare the size of two or more numbers in relation to each other.
The comparison between this two numbers or quantities is done and expressed by division.
Ratio of triangles to squares = number of triangles : number of squares
Ratio of triangles to squares = 4 : 20
Ratio of triangles to squares = 1 : 5
The best answer would be letter D. C<span>ompare the average number of tomatoes that are produced by 10 tomato plants that are grown in clay soil to the average number of tomatoes that are produced by 10 tomato plants that are grown in sandy soil.
It would be best to grow more than one tomato plant in each soil to truly represent the tomato's growth in them. To average the number of tomatoes yielded by each soil sample would also allow a sample that is more representative of the tomato plants than merely comparing single tomato plants.

Answer:
The path of cellular respiration that occurs in the mitochondria is aerobic.
Explanation:
Aerobic respiration is what uses oxygen to extract energy from glucose. It is carried out inside cells, in organelles called mitochondria, through which chemical energy is obtained from the breakdown of organic molecules.
To obtain glucose energy, a process occurs in which the carbon is oxidized and when it reaches the mitochondria it mixes with the water making a chemical compound called glucositisa ( pathway responsible for oxidizing glucose to obtain energy for the cell) in which the oxygen from the air is the oxidant used.
Aerobic respiration is a process consisting of chemical reactions that are grouped into 3 stages, taking into account the place of the cell in which each one develops.
1) Glucolisis: It is carried out in the cytoplasm.
2) Krebs Cycle: It is produced in the mitochondria matrix.
3) Respiratory Chain: Occurs in mitochondrial ridges.
The answer is Alfred Wallace.
Darwin began formulating his theory of natural selection in the late 1830s but he went on working silently on it for twenty years. He wanted to amass a wealth of evidence before publicly presenting his idea. During those years he corresponded briefly with Wallace (right), who was exploring the wildlife of South America and Asia. Wallace supplied Darwin's help publishing his own ideas on evolution. He sent Darwin his theory in 1858, which, to Darwin's shock, nearly replicated Darwin's own.
