As Marta wants to explain the water cycle, it is best to do it via video simulation of the cycle. The correct option is C.
<h3>What is water cycle?</h3>
The water cycle depicts the consistent flow of water within the Earth's and atmosphere's ambience.
It is a complicated system with numerous mechanisms. Liquid water evaporates into water vapor, condenses into clouds, and falls back to earth as snow and rain.
Marta's best bet for explaining the water cycle is to use a video simulation of the cycle as video is the best way to understand the process.
Thus, the correct option is C.

Answer:
Kidneys : helps in forming urine
Ureter : They are connected to kidney and by peristaltic action transports urine from kidneys to bladder .
Urinary bladder : It is an hollow sac that holds the urine .
Urethra : transports urine from the bladder to outside of the body .
Explanation:
The human excretory system consists of : Kidney ,ureter ,urinary bladder and urethra .The figure is shown below .
Now , as far as functions are concerned we have :
Kidneys : They have excretory units called nephrons that further consist of :
- Bowman's capsule
- PCT (Proximal convoluted tubule )
- DCT (Distal convoluted tubule)
- CT (collecting tubule )
In nephrons urine is formed and via ureter it is transported to a hollow sac like structure called urinary bladder .
This bladder has muscles that cant remain contracted up to longer period )and then voluntary and involuntary it is excreted through urethra .
The process of passing urine is called Micturition .
Answer:
B
Explanation:
unusually weak magnetic fields on the sun paired with reduced solar activity cause sunspots to disappear.
The first stage of gene expression is the transcription step, ie the passage from ADn to mRNA, the RNA polymerase will read DNA (the TAC sequence) and will synthesize a complementary strand (AUG) in the form of mRNA (which will then undergo mRNA processing).
The second stage of gene expression is the translation of mRNA into protein: the AUG sequence of mRNA (supposed to be the start codon) is translated to the amino acid, methionine, via the ribosome and tRNA. The ribisome will read adjacent codons to form the polypeptide (several amino acids bonded together by peptide bonds).
Answer:
Here's an explanation instead:
Explanation:
ALL STARS BEGIN IN A STELLAR NEBULA / NEBULA
Depending on how much mass the star has, it changes what path of life cycle it will take. Low mass or average mass stars become an average star, also called a main sequence star. It swells after millions of years into a Red Giant which is GIANT. Many many many years later, it becomes a planetary nebula, and finally becomes into a white dwarf.
If the star has a large mass, it is classified as a massive star, and also goes through a form of main sequence. It swells into a MASSIVE GIANT TREMENDIOUSLY LARGE AND UNNECCESSARILY BIGGO star called Red Supergiants. After millions and billions of years, it becomes a Supernova, which finally becomes a black hole if the outer layers literally get blown off into space and the core collapses and gets compacted into incredibly dense Nano-Googleplex sized molecules. If it doesn't, it becomes a cool Neutron Star.
I cannot drag tiles around, because there is no tiles or labels, however, I hope you get the point from this weird answer.
