Answer:The constituents of a solid can be arranged in two general ways: they can form a regular repeating three-dimensional structure called a crystal lattice, thus producing a crystalline solid, or they can aggregate with no particular order, in which case they form an amorphous solid (from the Greek ámorphos, meaning
Explanation:
The variables are the factors, which do not have a fixed value. Their value keeps changing in an experiment. It can be divided in two types: dependent variable and independent variable.
The dependent variable in the experiment is the variable, whose tendency to vary depend on other factors. To test this hypothesis, the rate of photosynthesis with respect to different wavelengths. So, the dependent variable is rate of photosynthesis, as it is dependent on the wavelength of the light.

please helpppppp
Answer:
1. b. homeostasis: The internal balance of heat within an organism is maintained by the process of homeostasis. It is the ability of the organism to maintain the internal body temperature with respect to the changes that occur in the external environment.
2.d) human: The human beings are capable for maintaining the internal temperature due to homeostasis because they exhibit fat which allows them to maintain the internal heat.
3.c) the guard cell lose pressure and the stomata open: The stomata are small pores present on the underside of the leaf surface these are important for exchange of gases and water to the external environment. The water is lost by the stomata of the leaf during transpiration. When the plant requires to remove excess of water from the plant body it is evaporated from the stomata through transpiration.
