Answer:
cellulose
Explanation:
it is not the true polymer
Answer:
A) repressors
Explanation:
A transcription factor is a protein that controls the rate of transcription of genetic information from DNA to messenger RNA, by binding to specific DNA sequence. The function of TFs is to regulate-turn on and off genes-In order to make sure that they are expressed in the right cell, at the right time and in the right amount throughout the life of the cell and the organism. Groups of TFs function in a coordinated fashion to direct cell division, cell growth and cell death throughout life.
Hi there!
The cell theory states that all cells can make duplicates of themselves. They do this by dividing themselves in half, until they are two cells.
The cell which divides itself in half is called the parent cell, and the cells that are produced from this are called daughter cells.
The origin of the cell, would most likely be the parent cells.
Hope this helps!

Answer:
1. the middle piece contains the chromosomes. FALSE
2. the tail contains the mitochondria. FALSE
3. the acrosome is next to the tail. FALSE
4. the head contains 46 chromosomes. FALSE
5. the acrosome is next to the nucleus, and the head contains 23 chromosomes. TRUE
Explanation:
The major parts of a mature spermatozoan in human males are the head, middle piece and the tail. The head of the sperm is a flattened and pointed structure that contains a nucleus. There are 23 chromosomes present in the nucleus. Chromosome surrounds the anterior two-thirds of the nucleus. The acrosome is a caplike vesicle and is filled with hydrolytic enzymes that help a sperm during fertilization. The middle piece contains mitochondria that provide the energy (ATP) for locomotion of sperm to the site of fertilization and for sperm metabolism.
Pompe is a disease in which u have a defect in the lysosome (an organelle found in every eukaryotic cell). The gene should be making a certain enzyme but it doesn't. This causes things to build up in cells that shouldn't be there. This type if disease is progressive and can be fatal. The treatment for this disease is very expensive. A person would need enzyme replacement therapy...which is not cheap. It will drastically affect a person's life. One can have progressive muscle weakness (where they require a walker or wheel chair), respiratory problems (where a breathing tube might be needed) , and heart defects.
