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:
The answer is movement toward or away from Earth.
In astronomy, it is said that the Doppler effect tells Astronomers whether a star, or galaxy, is approaching or going away from us. It turns out the farther a galaxy is away, the faster it gets away from us - meaning that the Universe is expanding.
hope this helps :)
The energy from sunlight comes in the form of photons, and this energy is used in the light dependent reactions of photosynthesis. The first function carried out by the photons in energizing electrons in the chlorophyll. The energized electron travels through the electron transport chain and subsequent steps are carried out to utilize this energy to form ATP.
<span>Trophic level—90% of energy consumed at trophic
level is used by the consumer for survival and reproduction. The remaining 10%
is transferred to the next trophic level. So the answer is 10,000 x 0.9
or 9,000 calories will be generally available

Which of these values would most likely be the heritability of body mass index (BMI) in a developing country with a large gap between nutrition and health care available to the rich and poor?
a. 0.33
b. -0.88
c. 0.99
d. 0.0001
e. 1.3
Answer:
a. 0.33
Explanation:
Body Mass Index is defined as the measure of fat depending on the height and weight of individuals. It is being calculated as: BMI=
The most likely heritability of body mass index(BMI) in a developing country with a large gap between nutrition and health care will be 0.33.
These is because in developing countries especially countries experiencing rapid economic growth as illustrated by the annual GDP growth rate are likely to have widely ranging lifestyles due to influences of the burgeoning economy, Therefore, there are greater chances for the rich to have access to the basic requirements and necessities of life whereas the poor are limited with either low or no access to adequate nutrition and health care.
