In an experiment, if we want to know how the amount of water affects plant growth, the amount of water is the ___. A. independent variable B. dependent variable C. control variable D. experimental variable 相关知识点: 试题来源: 解析 A。在这个实验中,水量是我们主动改变的变量,所以是独立...
Three major factors impact plant growth and development: the intensity of light, the duration, and the spectrum. However, there are lots of other factors to keep in mind, too. For example, temperature. The majority of plants can tolerate some temperature fluctuations, particularly those that migh...
While not immune to changing climate, plants respond to the rising mercury in different ways. Temperature affects the distribution of plants around the planet. It also affects the flowering time, crop yield, and even resistance to disease. “It is important to understand how plants respond to t...
We use Caltha palustris "a common wetland plant" to study whether warming affects growth and reproduction differently depending on origin of source population, potentially affecting phenotypic response to local climate. We conducted a 2‐year in situ temperature manipulation experiment using clone pairs ...
MALE STUDENT: So cold-blooded animals, like reptiles—they can't control their own body temperature, so I can imagine the effect a microclimate would have on them… FEMALE PROFESSOR: Yes. Many reptiles and insects rely on microclimates to control their body temperature.A lot of reptiles use ...
(touch response inDionaea, from trigger hair to trap lobe) and affects also information exchange between organelles (light response inHordeum, from chloroplast to nucleus). If you apply touch, wound or heat stimuli to your skin, you will not be able to realize them under anaesthesia because ...
Under a higher emissions scenario, plants typically grown in the Southeast could become established in the Midwest by 2100.Plant winter hardiness zonescould shift with the increasing temperatures and lengthened growing seasons. Each zone represents a 10°F change in minimum temperature for growth. Some...

Despite the use of the descriptive wordenvironmental, however, these plant growth factors should not be interpreted as referring only to the external factors which humans easily perceive. Although included, they do not refer only to sunlight, temperature, dry or moist air, and other elements ofcli...
With the intensification of the greenhouse effect, a series of natural phenomena, such as global warming, are gradually recognized; when the ambient temperature increases to the extent that it causes heat stress in plants, agricultural production will in
