Drag each label to the correct location. Each label can be used more than once. In a hydropower station, water stored in dams is
Nataly_w [17]

Answer:

Stored water - gravitational energy

Water fall - kinetic energy

Turbine - kinetic energy

Powerlines - electric energy

Explanation:

Dams are used to store or hold water for hydroelectric power plants. This stored water which has gravitational energy is a form of potential energy.

When the water is left to fall and run fast through the turbine, the gravitational energy is transformed into kinetic energy which makes the turbine to spin.

As the turbine spins, kinetic energy that is produced also powers the shaft of the engine in the electric generator, which produces electricuty.

Kinetic energy is transformed to electric energy and transmitted along powerlines.

*See attachment below for labelled energy that is being transformed at several points.

Which two factors of a molecule determine whether or not it can cross the membrane? A. Color and weight B. Shape and texture C.
myrzilka [38]
D. Polarity and size. 
<span>The size, polarity, and charge of a substance will determine whether or not the substance can cross the cell membrane by diffusion. The cholesterol was an example of a lipid, and is highly soluble in the nonpolar environment of the lipid bilayer. You saw, in the animation above, the cholesterol freely passing into the hydrophobic environment of the membrane. Cholesterol distributes freely in the membrane and then some fraction will dissolve in the aqueous environment of the cytoplasm. Water, on the other hand, while polar, is small enough to cross the membrane at a slow rate. Note that specialized transport proteins in certain cell membranes can provide a channel for the water, greatly increasing its rate of crossing the membrane. The lipid bilayer is much less permeable to the ion, because of its charge and larger size. As a general rule, charged molecules are much less permeable to the lipid bilayer.</span>

Which scenario is the best example of competition between individuals of the same species
mylen [45]

Answer:

For example, cheetahs and lions both feed on the same prey; they compete for this resource. Therefore, if they live in the same area, one or both species will have less food. You might expect them to fight each other over food, but they do not

An instrument used for the visual examination of the ear is called a(n):
Alina [70]
The correct answer is tympanometer. A tympanometer is not used to measure hearing, but to rather measure the transmission of energy through the middle ear. In this way, tympanometry is an objective test of the function of the middle-ear. Tympanometry is used alongside other measures to asses hearing, such as pure tone audiometry.

What do crops of the green revolution need in order to produce higher yields?
Airida [17]

Answer:

These crops where improved  with technology, production of high-yielding variety, and improve farm practices. All these ensured  the crops of green revolution had increase yield.

Explanation:

Through  genetic engineering, high-yielding variety of cereals e.g wheat, maize, rice, were genetically engineered so that certain features which enhanced increased productivity were selected for.

Use of fertilization, the adoption of mechanization,good cropping and farming system are other factors which enhanced yield of these crops. Specifically, these crops were modified to enhance their Nitrogen uptake, which promotes rapid growths.
