A researcher determines an organism to be eukaryotic, unicellular, and autotrophic. In which taxonomic group should this organis
Aleksandr-060686 [28]

According to the characteristics of this organism, it is classified into the Protist kingdom, which brings together unicellular or simple multicellular organisms that do not form tissues, both autotrophic and heterotrophic.

<h3>What is the kingdom protista?</h3>

It includes eukaryote-type organisms that, due to their characteristics, cannot be included in the rest of the kingdoms of this class.

Although most protists are unicellular, there are also multicellular protists and they can have autotrophic or heterotrophic metabolisms.

Therefore, we can conclude that the protist kingdom groups living beings that have cells belonging to the eukaryote group.

grigory [225]

Answer:

1. How did the tidal wave  affect the predicted frequencies of the alleles in the population?

No changes

2. What is the frequency of the recessive allele?

q= 0.6

Explanation:

If we assume that all individuals were equally likely to be wiped out, that means the frequency/ratio of the gene and genotype of the population will not change. The tidal wave killing 100 out of 200, so it simply makes the population become half of it used to be.  

If the population at equilibrium, we can use the Hardy-Weinberg formula to find out the expected frequency of the dominant and recessive alleles. There are 36 homozygous recessives out of 100, so the frequency of the recessive allele will be:

q^2 = 36/100

q= √36/100= 6/10= 0.6

Cytokinesis is the final act of cell division. In a typical animal mitosis, a cleavage furrow forms at the equatorial cortex after anaphase. This furrow then advances inwards to separate the two daughter cells.
