Answer:
The advantage of small cell size is that substances like organic molecules and ions can diffuse easily into the cells whereas wastes can diffuse easily out of the cells.
The correct answer for the question that is being presented above is this one: "Yes, because the observed changes in histone modifications are consistent with reduced transcription." The results shown in Figure 19.5 prove conclusively that histone modifications are causing reduced Hnf4a gene transcription because <span>the observed changes in histone modifications are consistent with reduced transcription.</span>
Answer:
They speed up chemical reactions. Without them you wouldn't be alive. They break down macromolecules, and also lower the amount of energy needed for a chemical reaction to happen.
Answer:
Cellular respiration takes place in mitochondria of a cell, hence it is also known as power house of cell , because it gives us energy in the form of ATP molecule .
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.
