Which of the following sources of electricity DOES NOT employ the use of turbines?
A
Solar
B
Wind
C. Hydro
D.
Fossil Fuels
=========================================================
Explanation:
The sources of wind, hydro, and fossil fuels all use a turbine. So we can rule out choices B,C, and D.
A turbine is basically a wheel that spins to generate motion energy into electrical energy. Think of it like one of those stationary bicycles and the bike powers up a nearby lamp (the faster you pedal, the brighter the bulb gets). Another example that's similar to a turbine would be those flashlights where you can rotate a crank to have the light come on (which is useful for when the batteries are completely dead). The windmill blades act as a giant turbine that the wind spins around. Hydroelectric turbines are spun by the falling water. Fossil fuels are burned to create very hot steam which then powers a turbine. Even nuclear power uses turbines as well. With fossil fuels and nuclear energy, the idea is to heat up a vat of water and then turn that intensely hot steam into electrical energy through a turbine.
With solar panels however, the electrical energy is converted through a process of sunlight interacting with the solar cells that doesn't require a turbine. This explains why you can use solar panels to power up devices such as phones or laptops without having any moving parts. All you need is a flat set of solar panels.
There is a slight variation of solar power known as "concentrated solar power", aka "concentrated solar thermal", where solar panels are not used. Instead, a vast array of mirrors are set up to aim the suns rays at a very specific narrow area. Think of it like a magnifying glass to focus the suns rays. The place where the narrow beam hits has a very high temperature. This high temperature heats up water to turn to steam, and the process from here is effectively the same as fossil fuels or nuclear energy. So that means turbines are involved with concentrated solar power. I'm assuming your teacher is specifically referring to solar panels when they mentioned choice A.
Describe latitude and why it feels warmer at the equator than the poles.

why are myxozoans actually a bad example of supposed evolution in action?
(I will give the best answer brainiest and extra points)
Explanation:
Myxozoans (phylum Myxozoa) are metazoan parasites utilizing invertebrate and (mainly) aquatic vertebrate hosts. They have in common with cnidarians the possession of virtually identical, highly complex organelles, namely the polar capsules in myxozoan spores, serving for attachment to new hosts and the nematocysts in surface epithelia of cnidarians, serving for food capture. Although myxozoan spores are multicellular, the simple trophic body forms of almost all species, reduced to syncytial plasmodia or single cells, reveal no clues to myxozoan ancestry or phylogenetic relationships. The myxozoan genus Buddenbrockia is one of only two known genera belonging to a clade which diverged early in the evolution of the Myxozoa. Today the Myxozoa are represented by two classes, the Myxosporea, containing all the better-known genera, which alternate between fish and annelids, and the Malacosporea, containing Buddenbrockia and Tetracapsuloides, parasitising bryozoans. The latter genus also infects salmonid fish, causing proliferative kidney disease (PKD). The enigmatic Buddenbrockia has retained some of its ancestral features in a body wall of two cell layers and a worm-like shape, maintained by four longitudinally-running muscle blocks, similar to a gutless nematode and suggestive of a bilaterian ancestry. Although some analyses of 18S rDNA sequences tend towards a cnidarian (diploblast) affinity for myxozoans, the majority of these studies place them within, or sister to, the Bilateria. The latter view is supported by their possession of central class Hox genes, so far considered to be synapomorphic for Bilateria. The simple body form is, therefore, an extreme example of simplification due to parasitism. Various hypotheses for the occurrence of identical complex organelles (nematocysts and polar capsules) in diploblast and triploblast phyla are evaluated: common ancestry, convergent evolution, gene transfer and, especially, endosymbiosis. A theory of the evolution of their digenetic life cycles is proposed, with the invertebrate as primary host and secondary acquisition of the vertebrate host serving for asexual population increase.
What percentage of a persons genes come from each parent?
Answer:
50% from mother 50% from father
Explanation:
Hello kassidyy00, the answer you have is correct. When a baby is consummated it will receive half of its genes from its father and half from its mother. This is due to the 22 chromosome pairings known as “autosomes” each being made up of 2 single stranded DNA segments of equal length.

if a 1st quarter moon phase appears on the night of july 4th, what is the approximate date in which a 3rd quarter moon will appear in the night sky?
Answer:
18th of July
Explanation:
Given that each quarter of a moon phase occurs after seven days, hence, if a 1st quarter moon phase appears on the night of July 4th, the approximate date on which a 3rd quarter moon will appear in the night sky on the 18th of July.
This is because, after the first quarter of a moon phase of July 4th, the second quarter of a moon phase will occur on the 11th of July, while the third quarter will occur on the 18th of July.

What is Newton's third law of motion
Answer:
His third law states that for every action (force) in nature there is an equal and opposite reaction.
Explanation:
You are provided with three solutions: A, B and C. One solution contains the enzyme amylase, one contains starch and one contains glucose. Starch if the substrate of the enzyme. The product is sugar maltose. You are provided with only one reagent, Benedict’s solution, and the usual laboratory apparatus.
7.1 Outline the procedure you would follow to identify the three solutions
Answer:
The procedure you would follow to identify the three solutions A, B and C by Benedict’s test;
- a brick-red precipitate will be seen, with the glucose solution that is a positive result, separate remaining solutions in boiling water to a high temperature until enzyme will be denatured.
- Mix these heated solution samples with the sample of the other solution;
Allow the solution to react and then carry out Benedict’s test on the two tubes; one will produce the positive result for the benedict test due to the presence of maltose sugar.

Explanation:
:3
The bones in cats' legs that help them walk are extremely similar to the bones in whales' flippers that help them swim. It exemplifies homologous structures.
What are homologous structures?These are similar in structure and location but perform different functions. They result in divergent evolution.
What are analogous structures?These are similar in function but have different origin and structures. They result in convergent evolution.
What are vestigial structures?These structures do not perform any function and are present in a residual form in the body
What is endosymbiosis?It is a kind of relationship in which one organism resides inside the body of the other organism.

C. Bluegills must require less nitrogen than trout.
D. Bluegills must have a greater population size.
Answer:
D. Bluegills must have a greater population size.
Explanation:
Hope this helps!
Trout fish are slowly replaced by Bluegills fish because Bluegills must have a greater population size.
What is Lake Succession?
Lake succession is a term used to describe the process of continuous aging in a lake in terms of its physical and biological properties.
As the population size of Trout fish is lesser, and the process of succession happens, it is replaced by the species that have greater population size.
Therefore, Trout fish are slowly replaced by Bluegills fish because Bluegills must have a greater population size.
