Answer:
Oxygen was not present on early earth
Answer:
carbon, hydrogen and oxygenation
Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves. Transpiration also includes a process called guttation, which is the loss of water in liquid form from the uninjured leaf or stem of the plant, principally through water stomata.
Studies have revealed that about 10 percent of the moisture found in the atmosphere is released by plants through transpiration. The remaining 90 percent is mainly supplied by evaporation from oceans, seas, and other bodies of water (lakes, rivers, streams).
Transpiration and plant leaves
Plants put down roots into the soil to draw water and nutrients up into the stems and leaves. Some of this water is returned to the air by transpiration (when combined with evaporation, the total process is known as evapotranspiration). Transpiration rates vary widely depending on weather conditions, such as temperature, humidity, sunlight availability and intensity, precipitation, soil type and saturation, wind, land slope, and water use and diversion by people. During dry periods, transpiration can contribute to the loss of moisture in the upper soil zone, which can have an effect on vegetation and food-crop fields.
Answer:
Yes (It's more inefficient)
Explanation:
in ecology there are things called primary producers (plants) that are eaten by primary consumers (cows and chickens) and then there are humans, secondary consumers, that eat cows and chickens for energy.
The further we move from eating primary producers the more inefficient we become in consuming energy. Meaning, it requires a lot more natural energy consumption to support a human that lives on meat only as compared to a human that eats plants only. this inefficiency only magnifies when communities practice unsustainable food methods.
There are sustainable ways to eat meat, but (at least in the US) our current conventions of meat production are unsustainable and environmentally destructive.
Answer:
B) Multicellular Simple gland
Explanation:
Exocrine Glands:Glands that secrete their products onto the apical(or epithelia) surface directly or via epithelial ducts or tubes that are connected to the apical surface. These Exocrine glands are composed of highly specialized epithelial cells..
Exocrine glands can either be branched or Unbranched based on the arrangement.
*Multicellular simple glands*:Glands that have an *unbranched duct* into which cells secrete. Each secretory portion empties separately on an epithelial surface.
