Answer: Rosa's errors were options
A: Wind does not easily produce a lot of electricity.
C: Geothermal energy causes a lot wind pollution.
Explanation:
Wind Energy is the use of wind (kinetic energy) to provide mechanical energy and electricity through wind turbines. The wind turbines in a Wind farm ( made up of several wind turbines connected together) are then connected to electric power transmission network to generate electricity to households and grids.
Electricity is measured in Mega Watts (MW); Rosa is wrong because wind energy amounts for a significant percentage of electricity used in some developed worlds and mostly the European Union (EU) at a recorded 270 Giga Watts (GW). It is estimated that by 2020, wind energy will produce 50 percent of energy used by the EU.
Geothermal energy is the thermal energy (temperature of matter) which is gotten from energy generated and stored in the earth. Geothermal energy comes from radioactive decay of materials and the formation of earth.
Rosa is wrong, because Geothermal energy is environmental friendly and does not cause significant pollution. It does not involve fuel to harness its energy which in turn leads to stable electricity prices.
Answer:
The arrangement of thin and thick filaments in myofibril.
Explanation:
Myofibril is defined as the basic rod like structure present in muscle cells. They are made up of long proteins including titin, actin, and myosin, and other proteins are helping them to hold together. The organization of these proteins are thin, and thick filaments which is known as myofilaments.
Thin filaments: Contains the actin protein which is coiled with filament nebulin.
Thick filaments: Contains the myosin protein. It is also known for force generation.
Answer:
No; the frog is eating food as a whole, so its mode of feeding is swallowing
Answer:
Within double-stranded DNA, the nitrogenous bases on one strand pair with complementary bases along the other strand; in particular, A always pairs with T, and C always pairs with G. Then, during DNA replication, the two strands in the double helix separate.
Explanation:
The four nitrogenous bases of DNA are thymine, adenine, guanine, and cytosine. Guanine and cytosine are bound together by three hydrogen bonds; whereas, adenine and thymine are bound together by two hydrogen bonds. This is known as complementary base pairing.
