Answer:

Explanation:

Farming is a process that requires constant supply of water to aid crop production. During the ancient civilization in Mesopotamia, farmers grew crops in lands that had little rainfall and inadequate supply of water. What they did was to develop a means of controlling the flow of water from the river and channeling it to their farms. This was done by setting up canals and irrigation ditches to redirect the water to their farms. Regulators were developed to control the level of water in the ditches and canals, making it accessible to the farmers. At that time, each farmer was permitted to use a certain amount of water. The farmers take turn to water their field. When it was the turn of a farmer, the regulator is adjusted to allow the outflow of water from the canal into an irrigation ditch and finally, into the farmer's field.

T is tall while t is short. Choose all the genotype(s) for tall individuals.

Furkat [3]

Answer:

Option (A), (C) and (D).

Explanation:

The concept of law of dominance was explained by Mendel while working on the pea plant Pisum sativum. According to this law, the trait which is able to express itself even in hetrozygous condition, the trait is called dominant trait. The trait that are unable to express itself, the trait is called recessive trait.

Here, T means tall and t is short. T shows the dominant trait whereas t is recessive trait. T trait can express itself in heterozygous condition as well. So, TT, Tt and TTTT shows the tall individuals and tt is short individual.

Thus, the correct answer is option (A), (C) and (D).

1. Photosynthesis and cellular respiration are often described in two ways: (1) They are chemically opposite; and (2) They have

SVEN [57.7K]

Answer:

Photosynthesis and cellular respiration are chemically opposite. The reactants of photosynthesis are energy, carbon dioxide (6CO2), and water (6H2O). The products of cellular respiration are energy, carbon dioxide, and water. The products of photosynthesis are glucose (C6H12O6) and oxygen (6O2), and the reactants of cellular respiration are glucose (C6H12O6) and oxygen (6O2). So, the processes' equations are chemically opposite. The relationship between photosynthesis and cellular respiration is such that the products of one system are the reactants of the other. Without photosynthesis, cellular respiration couldn't take place, and without cellular respiration, photosynthesis couldn't take place. It's like a cycle.
