Answer:
True
Explanation:
A DNA molecule is composed of the nitrogenous bases stacked inside the two backbones made up of the phosphate and sugar molecules. The nitrogenous bases form the nucleotide which when read in the triplets called codons code for specific amino acid and then form proteins.
If we say that we have to protect the DNA than it means that we have to conserve the DNA molecule. Conserving the DNA molecule means that the sequence of nucleotide which codes for specific proteins must be conserved as it is the protein molecule that is essential for survival.
Thus, true is correct.
Answer:
Genetic continuity is maintained by the Replication or Synthesis phase and the Mitosis phase of the Cell cycle.
Explanation:
- The Cell Cycle can be divided into the following phases,
- G0- Interphase.
- G1 - Growth phase.
- S - Replication or Synthesis phase.
- G2 - Second Growth phase.
- M - Mitosis.
- Of all the above phases, in the S phase the replication or doubling of the genetic material, that is, the DNA, occurs for equally distributing the genetic material to both the daughter cells.
- The M or the Mitosis phase is also essential to ensure that the distribution of the genetic material occurs accurately among the daughter cells.
- Hence, a genetic continuity is maintained across the generations of the cells.
Answer:In this GIZMO, your job is to arrange the LARGE organs in order from beginning to end.
BEFORE you do this, look at each of the organs listed. Place your cursor over each organ to
learn more about it.
ACTIVITY A: BUILD A DIGESTIVE SYSTEM
Now it’s time to design and build your own digestive system!
Start with the LARGE organs tab to build a basic system.
Click on the SMALL organ tab and read about each part.
Click and drag each of the SMALL organs to the proper location.
Follow the directions below.
Question Type Your Response
Which organs allow nutrients to be
absorbed?
Which organ stores and compacts waste
before it is eliminated?
Which TWO organs help to break down food
mechanically (physically)?
Which muscle contains ACIDS to help break
down food chemically?
Which muscle contracts to move food from
the mouth to the stomach?
Explanation:
Answer:
The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts.

From right to left.
1) Cytokinesis is almost
finished, so it’s the end of Telophase
2) The chromatids have just
split up and are migrating to each pole, so it’s Anaphase
3) All chromosomes are in the
equatorial plane, so it’s the end of Metaphase
4) The chromosomes are in the
poles and cytokinesis has just started, so it’s the beginning of Telophase
5) The spindle apparatus is
complete and the chromosomes are moving to the equatorial plate, so it’s the
beginning of Metaphase
6) The spindle apparatus is forming,
so it’s Prophase
If you want to put them in
chronological order, it’s like this:
6-5-3-2-4-1
