They are plants without a vascular system
Answer:
Yes, the child's blood type would be O.
Explanation:
Two parents with an A blood type can produce a child with either A or O blood types. Two parents with B blood type can produce a child with either B or O blood type. One parent with A and another with B can produce a child with A, B, AB, or O blood types.
Answer:
RNA is a polymer because it is made up of many monomers called nucleotides. Moreover, RNAs can form macromolecules because many RNAs are large molecules (i.e., polynucleotide chains).
Explanation:
Ribonucleic acid (RNA) can be defined as a single-stranded nucleic acid polymer of the four nucleotides. In RNA, each nucleotide is composed of a 1-ribose sugar, a 2-phosphate group and 3-one of four types of nitrogenous bases: Adenine (A), Cytosine (C), Guanine (G), and Uracil (U), which are covalently bonded to form polynucleotide chains. There are different types of RNAs such as mRNA, tRNA, rRNA, miRNA, circ-RNAs, lncRNAs, etc. Many of these RNAs form large single-stranded (ss) molecules, i.e., polynucleotide chains. For example, an mRNA sequence may have a length of 5,000 nucleotides (5 kb) or even more, and there are RNA viruses that have more than 20000 nucleotides (20 kb) in length.
Answer:
Where the crack is formed a new subduction zone slowly develops.
Explanation:
Tectonic plates are the pieces of the earth. If the distance between some parts of the earth becomes wide, the tectonic plate can crack. This is a way how the Himalayas are formed. These cracks can be easily seen as they are under the water.
Cracks can also be caused by earthquakes. In those cracks, the tectonic plates are touching. If they crash the pressure between the plates is big and they start to crack.
