Why are there four seasons?

Biology
2 answers:
7nadin3 [17]4 years ago
4 0

     The reason there are four seasons is that the earth is tilted 23.5 degrees on its axis. For half the year, this tilt causes one half of the earth to tilt toward the sun while the other half tilts away. This changes every six months, creating the seasons.

We have seasons because of our planets axis of rotation. Or in other words, the scientific word for this is <u>obliquity </u> . The earth is tilted at the angle of 23.5 degrees.  

Hope this helps! :)

Answer:

there must be large numbers of free amino acids present in the cytoplasm

Explanation:

<em>In order for translation to occur, </em><em>there must be a large number of free amino acids in the cytoplasm.</em>

<u>These free amino acids are usually carried by the transfer RNA which also carries the corresponding mRNA codon.</u>

During translation, as the codons in the mRNA match their complements in the tRNA, the amino acid being carried by the tRNA is released and a peptide bond is formed between subsequent amino acids until the required polypeptide bond is formed.

Translation and transcription only occur simultaneously in prokaryotic cells where there is no barrier between the cell's genetic materials and the cytoplasm, unlike in eukaryotic cells where the genetic materials are housed in the membrane-bound nucleus.

For which of these vehicles is the percentage reduction in the amount of hydrocarbon emission the most?
Bezzdna [24]

The car whose production of carbon dioxide is least will have the most percentage reduction in the amount of hydrocarbon emission.

<h3>What is a hydrocarbon?</h3>

A hydrocarbon is a compound which is composed of hydrogen and carbon only.

Hydrocarbons are important as they are commonly used as fuels for many vehicles.

The products of the combustion of hydrocarbons are carbondiodioxide, water and heat.

Because of the effect of carbon dioxide as a greenhouse gas, many vehicles are switching to fuels with less hydrocarbon emissions.

Therefore, a car whose production of carbon dioxide is least will have the most percentage reduction in the amount of hydrocarbon emission.

nignag [31]

Answer:

See explanation below.

Explanation:

Viruses cause problems when they enter the body and begin to grow and reproduce. They can have byproducts that are harmful. Strep throat for example gives off substances that cause inflammation in the throat. Some viruses can cause serious issues such as nerve damage, like polio. So the immune system works to recognize and deal with cells that might cause harm.

The first time that a particular virus moves in and attacks the body, the immune system - and the white blood cells - might be slow to recognize the issue and take some time to swing into action. But the next time that particular germs shows up, the body is ready for it and reacts much more quickly. The body us designed this way so that harm by invading germs can be halted or minimized.

Hope this helps! Have an awesome day!! :-)

If Planet Y orbits the Sun but does not rotate on its axis at all, how long would a day be on Planet Y?
drek231 [11]
I think the answer is D. due to the way an axis is leaning has to deal with how long the days are. And since it does not rotate it is staying at that one point and the time doesn’t change.
