How do abiotic factors in the environment affect ecosystems?

Biotic factors are all living organisms within an ecosystem. These may be plants animals fungi and any of the living things both biotic and abiotic factors are related to each other in an ecosystem,and if one factor is changed or removed it can affect the entire ecosystem

Abiotic factors determine which organisms can survive in an ecosystem because they are the non living objects in an ecosystem

Answer:

1) RNA strand =  <em>UCA  GCA  AAU</em>

<em>2) </em>Amino acids:   Asparagine       Arginine             Stop

                            (ASN)               (ARG)              (STOP)

Explanation:

Some theory that you need to know to answer the question:

Each tRNA has two important sites. One of them that couples with the codon of the mRNA molecule, named <em>anticodon</em><em>.</em> The other site couples with an amino acid through the action of the aminoacyl-tRNA synthase enzyme. The whole complex, amino acid + enzyme + tRNA is named aminoacyl-tRNA. Considering that there are twenty amino acids available, there are also twenty complexes of aminoacyl-tRNA, one for each amino acid.  

tRNA allows amino acids to align according to the nucleotidic sequence in the mRNA molecule.  

Once the new amino acid joins the growing peptidic chain, the binding between the amino acid and the tRNA molecule breaks. The tRNA is now free to join another amino acid and repeat the cycle.  

Now, to fill in the boxes, you need to pay attention to two things:

• <u>Anticodon</u>: In this box, you need to place the sequence of bases that pairs with the mRNA codon.  

• <u>Amino Acid</u>: In this box, you need to place the amino acid that is codified by the<u> mRNA </u>codon.  

For instance, let us say that the codon of mRNA is CUC. The anticodon for this sequence is GAG (because guanine joins cytosine and adenine joins uracyl).  

The amino acid places on the 3´extreme of the tRNA molecule will be the one that is codified by the codon, NOT the anticodon. So, as the codon is CUC, the amino acid will be Leucine, Leu. Do not use the anticodon GAG to fill these boxes. Remember that tRNA is translating information carried by the mRNA, so we need to use this information to grow the protein.

1)

Strand of DNI  →  AGT  CGT  TTA

  • Each of these letters are bases → Adenine, A - Guanine, G - Thymine, T - Cytocine, C
  • Each of these three-lettered groups are codons.

So, we need to pair these bases, knowing that:

Adenine (A) and guanine (G) derive from purines, while Thymine (T) Uracile (U), and Cytosine (C) derive from Pyrimidines.  

In the DNA molecule, Adenine (Purine) always pairs with Timine (Pyrimidine), while Guanine (Purin) forms pairs with Cytosine.

In the RNA molecule,<em> Adenine is paired with Uracil, U. </em>So, whenever there is an Adenine in the DNI strand, it pairs with Uracil of RNA strand. If there is a Thymine in the DNI strand, it pairs Adenine of the RNA strand. And, as always, Guanine pairs with Cytosine.

  • A ⇒ U
  • T ⇒ A
  • G ⇔ C

Knowing how to pair bases, we can fill the RNA molecule boxes.

  • Strand of DNI  →  AGT                   CGT              TTA
  • <em>Strand of RNA →  UCA                  GCA              AAU</em>

<em>                                      A ⇒ U              C ⇒ G            T ⇒ A</em>

<em>                                     G ⇒ C               G ⇒ C            T ⇒ A</em>

<em>                                     T ⇒ A                T ⇒ A            A ⇒ U</em>

2)

Now we need to translate these new codons of mRNA to amino acids.

<em>To fill the boxes you should have a genetic code chart to see the codons that codify for each amino acid. </em>

Codon:                 AAU                 CGA                UAG

Amino acids:   Asparagine       Arginine             Stop

                            (ASN)               (ARG)              (STOP)

<em>The new protein is synthesized from the amino terminus to the carboxy terminus of the mRNA molecule. The added amino acids to the chain are coded by a codon formed by three bases in the mRNA. mARNs also have a start and end codon that are the signals of the synthesis initiation and finish. When the ribosome reaches a stop codon, protein synthesis is over.  </em>

What is the effect of water temperature on corals from inshore and offshore reefs?
frez [133]

Answer:

When the water gets too warm, the algae can no longer live inside corals, so they leave. The corals then turn from green to white, called coral bleaching. Climate change has been causing the Earth's air and oceans to get warmer. With warmer oceans, coral bleaching is becoming more widespread.

The picture below shows a weather station model at a particular location.
g100num [7]

In the given scenario, the weather model is showing light rain, the correct option is B.

<h3>What is a weather station model?</h3>

Current weather circumstances, cloud cover, wind speed, prevailing winds, visibility, heating rate, dew point temperature, atmospheric pressure adjusted to sea level, and pressure change over the last three hours are all depicted in the station model.

As we discovered, the station model is a method of displaying a large amount of weather data on a single area using numbers and symbols.

Meteorologists can quickly glance at the map and see a lot of information this way.

In the given image, the three inverted commas are representing moderate drizzles.

Thus, the correct option is B.

Explain in detail the life cycle of the metamorphosis of amphibians.
ANTONII [103]

Answer:

Amphibians begin their lives as eggs, The few eggs that get fertilized, and survive will hatch in 7-9 days. After the eggs of an Amphibian hatch they are called Tadpoles. Tadpoles breathe through gills like fish. ... Metamorphosis is the final process that changes the amphibian from tadpole to adult.
