Answer:
Water!
Explanation:
A stream-lined and slippery body is the characteristic feature of aquatic organisms. The stream-lined body of aquatic animals helps them move easily in water. Possessing a streamlined body reduces resistance when moving whereas a slippery body provide resistance to parasites and also help some animals to breathe through their skin.
Hope this helps! :)
Answer:
The Thalamus relays sensory signals, regulation of consciousness, sleep and alertness. While the pons of the human brain act as message senders and receivers. It also connects the upper and lower part of the brain.
Explanation:
Crossing over is the main event in meiosis and heredity as it leads to genetic variation.
<h3>What is genetic variation?</h3>
Genetic variation is the changes that take place in the genes of individuals that can lead to the formation of new characters.
it generally occurs in meiosis specifically during crossing over.
Thus, it can be concluded that crossing over between non-sister chromatids during meiosis is significant in heredity as it leads to genetic variation.

The adhesion and cohesion of water is a result of water's ability to form hydrogen bonds. The way a water molecule is organized has one side of the molecule having a slight positive charge, while the other has a slight negative charge. The slight negative and positives are attracted to each other, making the water sticky in a sense, or more technically adhesive and cohesive.
This process is active transport.
Unlike other methods such as diffusion or osmosis, active transport requires extra energy provided by the organism from such as cellular respiration. In addition, they also require a carrier protein, which can change its shape to bring the substance through the cell membrane.
Some examples requiring active transport may include root hair cells absorbing mineral ions, or our small intestine absorbing digested nutrients into our body.
