Osmosis is 98% water and 2% salt inside the cell.
Answer:
Meiosis and Genetic Variation.
Explanation:
When homologous chromosomes form pairs during prophase I of meiosis I, crossing-over can occur. Crossing-over is the exchange of genetic material between non-sister chromatids of homologous chromosomes. It results in new combinations of genes on each chromosome.
When cells divide during meiosis, homologous chromosomes are randomly distributed during anaphase I, separating and segregating independently of each other. This is called independent assortment. It results in gametes that have unique combinations of chromosomes.
In sexual reproduction, two gametes unite to produce an offspring. But which two of the millions of possible gametes will it be? This is likely to be a matter of chance. It is obviously another source of genetic variation in offspring. This is known as random fertilization.
Answer:
A

If there are more predators than prey, the ecosystem will fall and the predators will die of starvation or cannibalism
Evolution is how we came to be as human beings ranging from rats, apes etc. This has helped us increase our survival skills and communication (ever since the beginning)
<u>Distress vocalizations</u> can help this rescue dog and firefighters find fearful people and pets stuck in buildings that are on fire
Distress vocalizations are sounds produced in the presence of painful, stressful, or threatening stimuli.
Mammalian vocalizations are the product of respiratory and laryngeal activities under the direct control of brain stem cranial and spinal motor neurons and modulated by higher brain processes.
Vocalizations offer the further promise of unique informational content about the emotional state of the subject. There is evidence that the form, contexts, and neural processes which modulate distress vocalizations are highly conserved between species.
