Answer:
Endosteum plays an important role in bone repair, bone remodelling and appositional bone growth.
Explanation:
Endosteum consists of a soft and thin connective tissue that lines the cavity of femur and humerus. Some of the major functions of endosteum are as follows:
Bone remodelling: Endosteum can stimulate the bone resorption that leads to the formation of new bone from the outside.
Bone repair: Hematoma, at the time of bone injury causes the division of endosteal cells and helps in bone repair.
Appositional bone growth: Endosteum that line the osteoblast cell can secrete bone matrix and increases the bone diameter.
They play an important role in the control system by sensing defects that occur during essential processes such as DNA replication or chromosome segregation, and inducing a cell cycle arrest in response until the defects are repaired.
The function of the cell membrane is to protect the cell from any outer surroundings that could be harmful to it.
Answer:
Explanation:
If there are 5 genes, let us assume that they are in the alternative forms with 2 possible gets for each five... So we have
2 possible gametes for each five = 2 to the power of 5 = 32 gametes
Then genotypes = 3 to the power of 5 = 243
The same also for 10 genes
2 possible gametes for each 10 = 2 to the power of 10 = 1024 gametes
Then genotypes = 3 to the power of 10 = 59,049
The same also for 20 genes
2 possible gametes for each 20 = 2 to the power of 20= 1,048,576
Them genotypes = 3 to the power of 20 = 3,486,784,401
Positive impacts of genetic engineering:
• New products are created such as food with higher nutrition values, drugs that are more effective and safer
• Disease prevention (“correcting” the genetic mutation, or removing disease-causing gene)
Negative impacts of genetic engineering:
• irreversible side effects, for example resistance of bacteria or introduction of viruses in human cells
• abusing like change specific traits that are not connected with diseases, create human outcomes that are ethically questionable.
