Answer:
D
Explanation:
During metaphase of cell division, the chromosomes line up in the metaphase plate and the spindle fibers from the poles extend and attach to the centromeres of the chromosomes. The spindle then contracts and pull different chromosomes to the opposite poles of the cell before the parent cell divides. If spindle fibers do not form, then the chromosomes will not separate during anaphase.
Therefore, the final cell after mitosis will be a cell with double the number of chromosomes -because if you remember, during interphase, genetic material is replicated so each daughter cell can have its copy-. Due to quality control in the process of cell divisison, this cell will mostly undergo apoptosis, otherwise, it could develop into cancer.
I believe the answer is chromosomes.
Chromosomes are basically coiled up pieces of DNA with proteins.
I hope this helps! If it doesn't, please reply.
<u>Answer:</u>
The sequence of the bases in DNA is most important because it provides the instructions for the traits of an organism.
<u>Explanation:</u>
- 'Deoxyribonucleic Acid (DNA)' is an instruction carrier. DNA stores the information and passes it from one generation to another.
- It stores all the information that helps in growth, development and different characteristics developments.
- So, the 'sequence of DNA bases' is important to be transferred during the reproduction that transfers the characters from parents to children.
The question is incomplete as it does not have the options which are:
- Adjusts the positions of the head, the neck, and the trunk
- Perform respiratory movements
- Stabilize or position parts of the appendicular skeleton
- All of the above
Answer:
All of the above
Explanation:
The axial skeleton is the group of bones which forms the centre of the skeletal system. The central portion of the skeletal system includes bones of the skull, bones associated with the skull, the thorax, and the vertebral column (spinal cord).
There are 80 axial skeletal bones out of which 22 bones are present in the skull, 7 attached to the skull, 25 in a thoracic cage and 26 in the vertebral column.
The axial skeleton help maintains the position of the appendicular skeleton, maintain the posture of the body by maintaining the posture of the neck, head and trunk and also help in the respiratory movements.
Thus, all of the above is correct.
I think the best answer from the choices listed above is option B. Planning activities at your own home helps you avoid situations involving alcohol since alcohol use is almost always tied to group events outside the home. Alcohol is mostly present in parties and any group activities. Hope this answers the question.
