Why are babies born with cancer?
Babies can be born with cancer due to genetic mutations that occur during fetal development. These mutations can lead to abnormal cell growth and the formation of tumors in the baby's body.
What is the difference between primary and secondary nondisjunction?
primary can happen in meiosis and as a result produces gametes with more than or less than the original number of chromosomes. secondary occur in an individual whose chromosomes already has the wrong number because of non disjunction.
Which hormones must increase for endometrial growth to occur?
For endometrial growth to occur, the hormones estrogen and progesterone must increase.
Where in the process of meiosis does nondisjunction occur?
Nondisjunction can occur during the separation of chromosomes in meiosis, specifically during the anaphase stage. This can lead to an abnormal number of chromosomes in the resulting gametes.
What are the key differences between partial and complete molar pregnancies?
Partial molar pregnancies occur when two sperm fertilize one egg, resulting in an abnormal fetus with some fetal tissue. Complete molar pregnancies happen when an empty egg is fertilized by one or two sperm, leading to abnormal growth of placental tissue but no fetus. Both types can have serious health implications for the mother.
What is cancer and how does it occur?

What is neprhohydrosis?
Nephrohydrosis (synonym Hydronephrosis) Term popular in <nephrology> Abnormal enlargement of a kidney, may occur secondary to acute ureteral obstruction (kidney stone) or in chronic kidney disease.
Does plant growth occur at the lateral buds?
Yes, plant growth can occur at lateral buds. Lateral buds are potential sites for new shoot development and can give rise to branches or new stems. When activated, lateral buds can contribute to overall plant growth and branching.
What is an abnormal tissue?
Abnormal tissue refers to a group of cells that exhibit atypical growth or structure compared to normal tissues. This can occur due to various factors, including genetic mutations, inflammation, or infection, and often results in changes in function. Abnormal tissue can be benign, meaning it is not cancerous, or malignant, indicating the presence of cancer. The identification of abnormal tissue is crucial for diagnosis and treatment in medical settings.
Why is there cartilage in your kidney?
Cartilage does not naturally occur in the kidney. If cartilage is found in the kidney, it may be a sign of a rare condition such as a teratoma or other abnormal growth that needs further evaluation by a healthcare professional.
Why are babies born with cancer?
Babies can be born with cancer due to genetic mutations that occur during fetal development. These mutations can lead to abnormal cell growth and the formation of tumors in the baby's body.
The series of changes that occur after a disturbance in an existing ecosystem is called?
secondary succession.
When do atrial septal defects occur?
Abnormal openings in the atrial septum occur during fetal development and are twice as common in females as in males. These abnormalities can go unnoticed if the opening is small, producing no abnormal symptoms
What is the purpose of a parotidectomy?
to remove abnormal growths (neoplasms) that occur in the parotid gland.
When does secondary succession could occur after?
Secondary succession can happy after primary succession . Secondary can be independent but is not usually independent from primary succession.
What can cause Secondary encephalitis?
Secondary encephalitis may occur with measles, chickenpox, mumps, rubella, and EBV
Is a tulip herbaceous or woody stem?
Is a tulip woody or herbaceous? tulip is herbaceous, because it is a monocot. secondary growth doesn't occur in monocots, whereas secondary growth produces cork, which is the woody stem found in dicots
