if you find a new species of algae floating on the surface of a coastal zone, you would likely consider it a type of .
Anna11 [10]

A new species of algae floating on the surface of a coastal zone, it is a type of <u>phytoplankton</u>.

Algae is an informal time period for a massive and various group of photosynthetic eukaryotic organisms. it is a polyphyletic grouping that includes species from a couple of awesome clades.

Algae belong to the dominion Protista whereas, fungi belong to the dominion Fungi. Algae are autotrophs, and Fungi are heterotrophs. Algae comprise photosynthetic pigments. Fungi are able to digest non-residing, natural fabric, and additionally absorb easy vitamins by the fungal hyphae.

A eutrophic lake is typically shallow with a smooth and mucky backside. Rooted plant boom is ample alongside the shore and out into the lake, and algal blooms are commonplace. Water clarity isn't right and the water frequently has a tea color. If deep is sufficient to thermally stratify, the bottom waters are devoid of oxygen.

Assume a population of purple and white flower pea plants (2000 total plants) is in Hardy-Weinberg equilibrium. The frequency of
lys-0071 [83]

Answer:

a) 0.48

b)

p= 0.4\\q=0.6

c) 720

Explanation:

Given ,

Frequency of white flower plant (p^2) is 0.16

Thus, frequency of dominant white allele (p) is equal to \sqrt{0.16} \\= 0.4

As we that, as per  Hardy-Weinberg equilibrium equation

p+q=1

Substituting the value of p in above equation, we get

0.4+q=1\\q=1-0.4\\q=0.6

a) As per Hardy-Weinberg equilibrium equation

p^2+q^2+2pq=1\\

Substituting the given and calculated values in above equation, we get -

0.4^2+0.6^2+2pq=1\\0.16+0.36+2pq=1\\2pq=1-0.16-0.36\\2pq=0.48

b) The frequency (decimal form) of the dominant allele

p= 0.4\\q=0.6

c) number of homozygous purple flower plants

= frequency of purple flower plants (q^2) * Number of flowers

= q^2 * 2000\\= (0.6^2)*2000\\= 0.36 * 2000\\= 720
