Answer:
The excessive alcohol consumption of the mother.
Explanation:
Alcohol consumption during pregnancy harms the developing baby, the foetus. This is because alcohol passes from the mother's blood to the baby's blood and this affects the growth of the baby's cell.
This causes severe damage to the cells of the brain and the spinal cord.
FASD - Fetal Alcohol Spectrums Disorder is characterised by growth and developmental problems and it can range from mild to severe.
Example is the baby having small head, narrow eye and behavioural problems later in life.
Answer:
Cartilage rings of trachea have protective role
Explanation:
Trachea is a tube, part of the respiratory system, which allows the passage of the air: from larynx to lungs (primary bronchi). It is enveloped with cartilage rings that prevent collapse of the trachea when there is no air. The cartilage "rings" are C-shaped, except one full ring-shaped - the cricoid cartilage which attaches trachea to the larynx.
Because types of chemicals in minerals need to form.
Answer:
Overthinking it.
Explanation:
Just go with with what you gut is telling you
There are five characteristics of Muscles; namely Responsiveness, Conductivity, Contractibility, Extensibility and elasticity.
Assigning each example to the universal muscle characteristic being described;
Conductivity; (electrically stimulating a muscle) Local electrical change triggers a wave of excitation that travels along the muscle fiber.
Contractibility; Shortens when stimulated
Elasticity; Returns to its original resting length after being stretched,
Extensibility; capable of being stretched between contractions.
Responsiveness; to chemical signals, stretch, and electrical changes across the plasma membrane.
