Some flowers are bilaterally symmetrical or zygomorphic or mono-symmetric as in these flowers only possible to draw a single line of symmetry through them. Whereas some flowers are radially symmetrical or actinomorphic or poly-symmetric. In them, many lines of symmetry can be drawn. Besides, some flowers are asymmetrical.
Orchid flowers show extreme bilateral symmetry. In Daisy flowers head or capitulum is radially symmetrical capitulum and ray florets are bilateral symmetry. Rose flower is radially symmetrical and <em>Wisteria</em> flowers are bilaterally symmetrical.
Answer:
Structure 1 is the stamen and structure is the pistil
Explanation:
Answer:
mRNA, tRNA, and rRNA
Explanation:
Translation is the second process of gene expression involving the synthesis of proteins from mRNA strand in the ribosomes. mRNA is the template for the translation process to occur. However, other certain molecules are necessary for the occurrence of translation.
The molecules that directly participates in the process of translation include:
- mRNA, which is transported from the nucleus into the cytoplasm (ribosomes) to be read.
- tRNA, this is a type of RNA present in the ribosomes whose function is to read the codons of the mRNA and carry corresponding amino acids to the peptide chain.
- rRNA, is another type of RNA that makes up the ribosomes and functions in the synthesis of proteins from the amino acids.
Answer:
Homo species have differences in brachial index, face and teeth size as compared with australopithecines.
Explanation:
Australopithecines were found in pleistoocene era and adapted to the bipedal locomotion but shows differences in walking style as compared to early homo species. They have large brachial index. The postcanines were large but incisors and canines were small.
Early homo species were found around 2 million years ago. They shows bipedal locomotion with different walking styles. The brachial index of early homo species was small as compared with the australopithecines. The post canines were small but incisors and canines were large.
