Answer:

DNA ligase is an enzyme which can connect two strands of DNA together by forming a bond between the phosphate group of one strand and the deoxyribose group on another.

DNA polymerase is an enzyme that synthesizes DNA molecules from deoxyribonucleotides, which are the building blocks of DNA. The enzymes play an essential role in DNA replication, usually working in pairs to produce two matching DNA stranges from a single DNA molecule.

DNA gyrase is an essential bacterial enzyme that catalyzes the ATP-dependent negative super-coiling of double-stranded closed-circular DNA

Helicases are enzymes that bind and may even remodel nucleic acid or nucleic acid protein complexes. There are DNA and RNA helicases. DNA helicases are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied.

The anterior portion of the body of most annelids, such as the earthworm, is adapted for sensing the environment.

Diano4ka-milaya [45]

Answer:

The answer is False. Although sensitive cells are more abundant in the anterior portion of the annelid´s body, in general, they are arranged in all the segments.

Explanation:

Annelids, such as the earthworm, have a variety of sensory cells:

Mechanoreceptors, disposed of in groups in each segment of their body.

Photoreceptors: Light-sensitive cells. Although they are located in the whole body, they are abundant in anterior and posterior segments, concentrated in the intern and dorsal part of the epidermis.

Humidity receptors are the most sensitive cells and are located in the first segments of the earthworm body

Chemoreceptors: sensorial cells cumulus forming a prominent tubercle with prolongations that extends through the cuticle. These tubercles form three rings in each segment but are especially abundant in the anterior part of the body.

The tegument is very rich in free nervous terminations, which functions might be tactile.

Which of these invertebrates have segmented bodies.?

zhuklara [117]

Answer:

The correct answer option is C. Annelids.

Explanation:

Annelids are the invertebrates that have segmented bodies.

The annelids or Phylum Annelida (also called ringed or segmented worms) are widely known for their characteristic of having segmented bodies.

These annelids contain largely segmented bodies with each segment having secondary subdivisions known as annuli which consists of elements of the different body systems which are essential for life, for instance the nervous system.

Which includes the physical characteristics of an organism

MariettaO [177]

The question is asking "which includes the physical characteristics of an organism Gene" and the answer is the phenotype. An organism's phenotype is basically its outward appearance and its phisical characteristics. In contrast, the other options, gene, allele and genotype, refer to the genetic make up of an organism - its genotype

The prefix mono- means “one” and the prefix poly- means “many”. How are these meanings related to the terms monomer and polymer

Dmitriy789 [7]

When a molecule is made up of one sugar unit, its called a monomer.

Eg. Glucose, galactose, fructose

When a molecule is made of more than one sugar units, its called a polymer.

Eg. Cellulose, glycogen

Polymers are usually macro molecules.
