<span>Hornworts are needle-like sporophytes that are a part of the group of bryophytes or non-vascular plants. They have horn-like or needle-like structures that have a flattened green plant body. These hornworts may be found all over the world but can only grow in places that are damp and humid. Some of its other species grow in large numbers as tiny weeds in garden soils and cultivated fields. While others in the tropical and subtropical areas grow on barks of trees.<span>

Explanation:
Complete Question: In apneustic breathing, which is practiced by most marine mammals:
A. A small amount of air is kept in the lungs before diving
B. A large amount of air is kept in the mouth before diving
C. Normal breathing is maintained before diving
D. Several deep breaths are taken before exhaling and diving
E. No actual breathing takes place before diving
Answer: D. Several deep breaths are taken before exhaling and diving.
Explanation:
Common dolphins, whales and other marine mammals are known to undergo apneustic breathing. This breathing process is characterized by periodic or several breathe inhalation, followed by holding their breath and then exhaling them.
Marine mammals can afterwards, went on to dive. This process prevent high water loss out. Thus, they make fewer respirations while maximizing the amount of oxygen produced for optimal consumption.
The answer is Fatty Liver
Answer/Explanation:
Normal cell division is a very controlled process.
There are several checkpoints where the cell ensures the cell is:
- receiving the correct signals to divide
- that the environmental conditions are favourable for the cell to divide
- that there is no damage to the DNA.
However, cancerous cells proliferate uncontrollably. This is because they can bypass the checkpoints and divide without the necessary signals. This means cell division keeps occurring even when conditions are unfavourable and the DNA is damaged.
