Answer:
Explanation:
The lamp and the ice bag were at the same place.
Sounds like the experiment was intended to show on a small scale ocean currents from the poles to the equator and back to the poles. The bag of ice would simulate the cold at the poles while the lamp would simulate the heat provided by the sun near the equator. With that in mind, let's look at the possible flaws and see what is likely.
Not enough ink was added.
* If you can see the ink, then there's enough ink. So this isn't the correct choice.
Not enough water was taken.
* Possibility there wasn't enough volume of water to setup a current, but not too likely since the baking dish was filled. So let's look further.
The dish was too small for the experiment.
* Same as above. It might be this, but there's something more likely.
The lamp and the ice bag were at the same place.
* This sounds like a winner. In the real world, the poles are cold and the equator gets more sunlight. So there's a temperature gradient. In the described setup, both the heat sink (the bag of ice) and the heat source (the lamp) were at the same location.
Answer:
Lysosome............Digest macromolecules.
Explanation:
Lysosomes is the membrane bound cell organelle that plays an important role in the cellular digestion. The proteins through the protein processing are transferred to the lysosomes as well.
Lysosomes are also known as suicidal bags as they have the ability to digest their own genetic material. The lysosomes contains acidic pH and different enzymes that are responsible for the degradation of macromolecules. Proteins, carbohydrates, lipids and nucleic acids are digested in the lysosomes.
Thus, the correct answer is option (a).
Answer: The correct sequence for the protein creation is as follows-
1) Information is transcribed in DNA to mRNA.
2) mRNA leaves the nucleus.
3) Ribosome attaches to the mRNA.
4) tRNA anticodon carries an amino acid that compliments the mRNA codon.
5) The chain of amino acids forms a protein.
According to the Central Dogma, the genetic information is transferred from DNA to mRNA to Proteins.
The first step is transcription in which DNA is converted to mRNA with the help of enzyme RNA polymerase. In eukaryotic cells, this process occurs in the nucleus.
This is followed by translation, which takes place in the cytoplasm when mRNA leaves the nucleus.
Ribosomes are the specialized organelles, which act as the site for protein synthesis ( translation).
Ribosomes attach to the mRNA. tRNA brings amino acid, which has anticodon complementary to the codon present in the mRNA. A chain of amino acids is thus synthesized, which is called Protein.
Explanation
Organisms from kingdom Plantae does have cell walls. Organisms from Animalia does NOT have cell walls. Fungi also does have cell walls. Prokaryotic Eubacteria includes bacteria with cell walls. Therefore, the organisms with cell walls are I, III and IV. The correct answer is C.
