Answer: right bottom is kidney
Left bottom is liver
Q. 4 part a, The excretory system.
B, kidney: The kidneys make urine by filtering wastes and extra water from blood. Urine travels from the kidneys through two thin tubes called ureters and fills the bladder.
And Q. 5 order, 3, 2, 1, 4.
Explanation:
Cations are positively charged and have more protons than electrons.
Anion is negatively charged and have more electrons that protons.
Cations examples: Hydronium is H3O+, Silver is Ag+
Anion examples: Sulfate anion is SO42-
Hope this helps.
Answer:
The tRNA would be unable to read the mRNA CODON, and will be unable to carry its corresponding amino acid
Explanation:
Protein synthesis occurs in two major stages; transcription and translation. Transcription involves the synthesis of a mRNA molecule while translation involves reading the sequence of the mRNA in order to synthesize amino acids that forms protein. Let's look at translation in details. Translation occurs with the help of a type of RNA molecule called transfer RNA (tRNA) present in the RIBOSOME (site of protein synthesis).
The tRNA possesses a group of three nucleotides called ANTICODON, which it uses to read the mRNA codon that is complementary to it i.e. an anticodon UAC will read mRNA codon AUG. The tRNA binds to the mRNA molecule in order to assess its nuceleotide sequence. Once, a complementary anticodon succesfully reads a particular mRNA codon, it carries the amino acid encoded by the mRNA codon it reads to the growing polypeptide chain. This is the normal translation process.
However, as stated in the question, that if a wrong anticidon successfully binds to a codon. This means that the anticodon that binds to the mRNA codon is not complementary to it. What would happen in this case is that the Anticodon will be unable to read that particular codon it binds to because the complementary base pairing rule is used to read i.e. A-U, G-C. Once, the anticodon cannot read the mRNA codon, the tRNA will also be unable to carry the amino acid that is encoded by that CODON.
The answer you're looking for is B. <u>/\</u>G is negative. I hope that this helps! Please leave brainliest if you can!
Answer:
acquisition
Explanation:
Flatworms are worms that appeared on Earth probably about 600 million years ago. They live mainly in aquatic environments such as oceans, rivers and lakes; They are also found in humid terrestrial environments. Some live free, others parasitize diverse animals, especially vertebrates.
These worms are extremely sensitive to certain light intensities, writhing quickly when an incident light causes electric shocks on their bodies. The moment that flatworms contort the body in the face of a light with gradually increased intensity is called acquisition.
