During blood typing, the blood plasma is checked for antibodies. This is what is meant by "anti" in the statements. Keep in mind that if the antibody against a specific blood type is present, the blood cannot have that type. So, if anti-A is present, the blood type is not A.
Moreover, the Rh antigen determines the positive (present of Rh) and negative (absence of Rh) nature of blood type. If the anti-Rh is present, the blood type is negative. Using this information, we see that:
a) A negative
b) B positive
c) AB positive
d) O negative (O because both anti-A and anti-B are present)
e) <span>AB negative (AB because neither anti-A and anti-B are present)</span>
Answer:
The animals are the consumers of the ecosystem but the fungi have wide range of nutrition from the parasites to the saprophytes mode. Animals have multicellular organization but fungi dont always meed to be multicellular, they may be unicellular also.
Transcription occurs in the nucleus of the cell. RNA polymerase breaks the hydrogen bonds and unzips a portion of DNA. RNA nucleotides match the DNA strand forming mRNA. In mRNA thymine is replaced by uracil. Once mRNA is formed it leaves the nucleus through a nuclear pore into the cytoplasm. The purpose of mRNA is to remove the protein code out of the nucleus without pulling the DNA out. mRNA then needs to find ribosomes in the cytoplasm which can be found on the rough ER. mRNA has read three bases at the same time and these are called codons. Ribosomes read the mRNA code and add the correct amino acid using tRNA. tRNA has an anti-codon on one end which will match a specific codon, and a specific amino acid on the other end. This will make translation happen.
Translation- mRNA attaches to a ribosome and a start codon must be read. tRNA brings the first amino acid which matches the codon on mRNA. The next tRNA molecule moves in and matches with the codon on mRNA while amino acids form a peptide bond. First tRNA detaches itself and mRNA shifts for the next tRNA molecule to come in. Protein grows until a stop codon is reached and then it's ready to finish folding to become functional.
Answer:
in many ways
Explanation:
if the animal does not receive the same nutrition that it would in the wild, the animal will become weaker. If the climate of the zoo is very different than the animals natural habitat, they will struggle to maintain homeostasis. If a dolphin, for example, is in a tank that is too small, it will struggle to grow and develop.
The answer is B) False because plates can move.
