Red blood cell
the biconcave shape helps it to squeeze through blood vessels smaller than itself and not get stuck inside (the lack of nucleus also helps it to do this as it has a smaller volume) and the haemoglobin causes the oxygen to stick to it to be transported to other parts of the body.
Answer: Pedigrees can show someone is a carrier for diseases by determining which parent, if not both, is either dominant or recessive. Each child must have a letter from their parent then that will determine if someone gets a disease or not then it goes on from generation to generation. However, they can be carriers of the trait, and if they are carriers, their male children will be colorblind. On a pedigree, carriers are represented either by a half-shaded symbol or a shaded dot in the middle of the symbol. brainliest??
Explanation:
Answer:
Adenine pairs with Thymine and Cytosine with Guanine. Thus : A-G-T-C-G-T is the correct answer.
Explanation:
According to Watson and Crick DNA base pairing, purine bind to the pyrimidine base whereas each purine binds to a particular type of pyrimidine.
Like adenine (A) binds with thymine (T) and guanine (G) binds with cytosine (C) in a DNA molecule.
Since, the given sequence is T-C-A-G-C-A, therefore, its nitrogen base sequence is A-G-T-C-G-T.
Natural selection is the process in which the more favorable traits due to mutation that are in a select few in a population produce more offspring then others. An example of this is bacteria resistant to antibiotics due to the faster reproduction of the resistant bacteria over the non resistant ones
