Why are there seasons? QUICKLY AND IT HAS TO BE A LONG EXPLANATION

Biology
1 answer:
Shkiper50 [21]2 years ago
5 0

Answer: Seasons occur because Earth is tilted on its axis relative to the orbital plane, the invisible, flat disc where most objects in the solar system orbit the sun. Earth's axis is an invisible line that runs through its center, from pole to pole. Earth rotates around its axis.

Compare the biomes of New York City and Seattle. Whey are their biomes different?
exis [7]

Answer:

New York City: temperate deciduous forest

Seattle: temperate wet forest

Explanation:

New York City is characterized by a <u>Temperate Deciduous Forest biome</u>. This indicates that its climate is not stable but, instead, faces constant changes. The seasons are clear and marked, e.g. summer is warmer and trees begin to lose their leaves during fall (as it is supposed to be). New York's biome is also characterized by the presence of rain throughout the year. Plants such as conifers and mosses are predominant and wildlife species like red foxes, squirrels, and owls inhabit in this city / biome.

Seattle, on the other hand, is characterized by a T<u>emperate Wet Forest biome</u>, that is, warm and dry-summer subtropical climate. The seasons are marked but not as predominantly as in New York. Seattle is also characterized by more humid conditions in contrast to New York. Moreover, summers tend to be drier and warmer, making it more vulnerable to bushfires. Plants such as the western red cedar and the ponderosa pine are predominant and wildlife species like deers, coyotes, and bears inhabit in this region.

There are 20 naturally occurring amino acids, therefore, there are only 20 mRNA codons. True or false
weqwewe [10]

Answer:

False. There are 20 amino acids, but 64 possible codons.

Explanation:

Genetic information for the aminoacids assembly during the protein synthesis is stored in short sequences of three nucleotides named codons in the mRNA. Each of the codons represents one of the 20 amino acids used to build the protein. The total number of possible codons is 64, from which 61 codify amino acids -more than one codon codify for the same amino acid-. One of these amino acids is also the start point of protein synthesis. And the left three codons are stopping translation points.

The codons indicating the initiation or stop points during the translation process are:

• The start codon AUG is the most common sequence used by eukaryotic cells and places near the 5´extreme of the molecule. However, other codons might be used as well. Prokaryote cells might use the codons GUG or UUG.

• The end codons are UAA, UAG, UGA.

NAD and FAD work by loading and unloading _________ and _________ during energy transfers.
andrezito [222]

Answer:

Hydrogen and electrons

Explanation:

Nicotinamide adenine dinucleotide (NAD) and flavin adenine dinucleotide (FAD) serve as reducing power during energy transfers. One NAD+ accepts one hydrogen ions and two electrons and becomes reduced into NADH. Likewise, FAD accepts two hydrogen ions and two electrons and is reduced into FADH2. Oxidation of NADH and FADH2 into NAD+ and FAD respectively releases both hydrogen ions and electrons.  

For example, some of the energy of glucose released during glycolysis and Kreb's cycle is temporarily stored in the form of NADH and FADH2. Oxidation of NADH and FADH2 via electron transfer chain of mitochondria releases both electrons and hydrogen ions (protons). The protons are pumped across the inner mitochondrial membrane to generate the proton concentration gradient.
