Answer:
It's important to not touch the sides or the bottom of the test tube with the thermometer because touching it to the sides or bottom of the test tube fractures the glass and does not allow for correct temperature measurements.
Answer: Both groups are bilaterally symmetric triploblasts with the protostome pattern of development.
Explanation:
Lophotrochozoa and Ecdysozoa are bilaterally symmetrical clade of aminals. They are triploblastic and they possess protostome pattern of development that is to say in their embryonic development, the mouth develops first before the anus.
Answer: C. It is the part of the stamen that contains the pollen
Explanation:
Anthers are the pollen containing units in a flower that can be found in the stamens of such flowers. It should be noted that typically, anthers consist of two parts which are referred to as the thecae and each one of the theca is made up of two microsporangia.
Therefore, from the explanation above, we can infer that the another is the part of the stamen that contains the pollen.
Answer:
Homology
Explanation:
Homology refers to the presence of similar or shared body structures, body parts, gene sequences, proteins, etc. among various lineages. It represents divergent evolution of these lineages from a common ancestor.
Presence of various similar structures in human and salamander reflects the fact that these two species have shared a common ancestor during their evolution. The shared ancestry between human and salamander led to the presence of various homologous body parts and identical gene sequences in them.
