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.

Why do field researchers and laboratory researchers use tools that are similar and tools that are different
34kurt

Answer:

Please see below

Explanation:

These two types of research, that is, in the laboratory and in the field, are very different from each other for a number of reasons. For one, the study is conducted on a much larger scale when it is done in the field as compared to when it is confined in the lab.

Tools such as PCR (polymerase chain reaction) would be common between the two since there is no substitute for it. However, other tools used that have various other purposes will be different between the lab and the field. For instance, a quadrant will be used to count plants in a field, but none is needed in the lab due to a smaller number of plants being studied.

How can an egg hatch in cold weather
olga2289 [7]

Answer:

Although eggs contain a great deal of water, they can get colder than 32°F/0°C without freezing. However, eggs that reach 29°F will freeze, which usually causes death.

Explanation:

If they have been exposed to very cold temperatures then I would assume the embyros would be dead or never started, though if you had a way to keep the coop warm or if she went broody and stayed on the eggs (is sitting and still laying eggs so they aren't exposed to some bitter cold weather or breezes) then they hopefully would be okay.
