Answer:
The factors which remained constant are as follows -
- material used as the membrane
- amount of substances used
- number of trials
The factors which have shown variation are as follows -
- molecule size (large starch molecules vs. small glucose molecules)
- whether the molecules diffused through the membrane (tubing)
Explanation
Some factors with in the experiments remained constant from the point of starting of the experiment to its end. While some factors were varied to study its impact on the experiment rate of progression or on the final product formed. Thus , out of the following given factors, the ones that remained constant are -
- material used as the membrane
- amount of substances used
- number of trials
The factors which have shown variation are as follows -
- molecule size (large starch molecules vs. small glucose molecules)
- whether the molecules diffused through the membrane (tubing)
Answer:
Development is largely under the control of genes. Mature cell types of the body, like neurons and liver cells, express different sets of genes, which give them their unique properties and functions.

RICE is the staple of South Korean diet while CORN is a staple of the US diet.
These preferences for food in these two countries are influenced by historical and social factors.
Most of the food in South Korea are usually prepared from rice while in the US most of the staple food are prepared from corn.
Answer:
There is an important relationship among homeostasis, defective mitochondria, and the symptoms caused by LHON.
Explanation:
There is a great relationship among homeostasis, defective mitochondria and the symptoms caused by LHON because defective mitochondria disturbs the homeostasis in the body. If mitochondria works properly, homeostasis will be maintained whereas if there is any defect occurs in the mitochondria then the whole homeostasis will be adversely affected because mitochondria is the powerhouse of the cell responsible for the production of energy for the cell. Symptoms occurs due to Leber's hereditary optic neuropathy (LHON) also effected the state of equilibrium in the body.
Solar- technologies convert sunlight into electrical energy either through photovoltaic panels or through mirrors that concentrate solar radiation.
Hydro- a hydraulic turbine converts the energy of flowing water into mechanical energy. A hydroelectric generator converts this mechanical energy into electricity
Tidal- energy is a form of hydropower that works by harnessing the kinetic energy created from the rise and fall of ocean tides and currents, also called tidal flows, and turns into unusable electricity
Wind- turns the propeller like blades of a turbine around a rotor, which spins a generator, which creates electricity
OTEC- plants pump large quantities of deep cold seawater and surface seawater to run a power cycle and produce electricity
Biomass- is burned in a boiler to produce high-pressure steam. This steam flows over a series of turbine blades, causing them to rotate. The rotation of the turbine drives a generator, producing electricity
Geothermal- power plants use steam to produce electricity. The steam comes from reservoirs of hot water found a few miles or more below the earth’s surface. The steam rotates a turbine that activates a generator, which produces electricity
