Answer:
maintain homeostasis
Explanation:
Lizards are poikilothermic organisms, it means that their body temperature varies over the course of the day. There are poikilothermic organisms including lizards that bask in the sun during the morning and evening hours, and thus they can increase the body temperature
If living space is reduced, then competition increases! if there's nowhere to go then there's going to be some pretty high tension!
Answer:
The correct option is A.
Explanation:
Here is the complete sentence: Hox genes APPEAR TO FUNCTION IN SIMILAR WAYS ACROSS DIVERSE GROUP OF ORGANISMS.
Hox genes refer to a group of transcription factor genes that control and regulate animals development. Hox genes function by specifying segment identity, that is, they are responsible for determining the parts of the embryo in which different structures will form. For instance, the genes determines the part of the embryo that will develop into head, legs, stomach, etc.
Hox genes are usually clustered together in a particular spot on the chromosomes and they are present in different forms of animals; the function of hox genes in these animals are similar.
Answer: They have low melting points.
Explanation: Ionic bonds are formed by a complete transfer of electron from a metal to a non metal. This loss and gain of electrons between atoms result in positively and negatives charged ions respectively. The compounds formed is usually ionic with high electrostatic force of attraction and this makes them to have high melting points because high amount of energy is needed to break the bonds between the atoms.
Correct option is b) A DNA polymerase that is a main polymerizing enzyme.
DNA polymerase have specific role in the replication of DNA process. In E.coli which replicates the genome from a single replication fork, the polymerase DNA POL III enzyme primarly responsible for DNA replication and then form replication complex with high processivity.
The polymerase is physically linked to clamp through a clamp interacting sequence motif. This interaction serves to increase the processivity of DNA polymerase. Because the when its high then synthesis DNA very quickly. This is due to part of the beta -clamp that hold on DNA stands.
