Answer:
allergic reaction
Explanation:
Difficulty breathing and getting swollen is a sign of allergic reaction
<em>Because for example one large eagle needs lots of small sparrows to eat. There is usually a food pyramid so for example you could display it along the lines of 1,000 worms are eaten by 20 sparrows which are eaten by 1 eagle. Its just the way things are. It is a fine balance. if you went up to two eagles on same land they would run out of food quickly and then would either starve or have to move on and using up all the food doesnt help them so it needs to be in a fine balance. A balanced ecosystem.</em>

During gametogenesis, if
nondisjunction occurs in meiosis II (meaning that that at least one pair of
sister chromatids did not separate), the resultant effect will be two cells that
has the normal haploid number of chromosomes (n), one cell that has an extra
chromosome (n + 1), and one cell that has one missing chromosome (n - 1). In
summary, two of the gametes will be n, one will be n + 1, one will be n — 1.
The correct answer is C. Trees provide oxygen for humans, so by reducing trees you reduce oxygen available for humans.
Answer: The genotype ratio is 2Ff : 2ff
The phenotype ratio is two normal feathered birds to two silky feathered birds.
Explanation: Let F represent the gene for normal feather and f represent the gene for silky feather. F is dominant while f is recessive, therefore a male that is hybrid for trait of normal feather is heterozygous and will have a genotype of Ff, a female that is homozygous for silky feather will have a genotype of ff.
A cross between Ff and ff will yield 2Ff birds and 2ff birds. Since F is dominant, a bird having genotype of Ff will manifest outwardly as blue feathered birds while ff will manifest outwardly as silky feathered birds because f is recessive and must occur in a homozygous condition in order to manifest phenotypically. Therefore, the genotype ratio is 2Ff: 2ff.
