Why are biologists still debating the classification of protozoans? A. Biologists never agree on anything. B. There are estimate
miskamm [114]

Answer:

B

Explanation:

Answer B is correct:

Because the biologists are continuing to learn more and more about such minute organisms, protozoan systematics – that is,  the taxonomy (classification) and the evolutionary interrelationships of major groups of protozoa – remains a  topic of debate and change, still today.

Some of the rather  LARGE and unwieldy taxonomic groupings of past years are  particularly subject to revision with expansion of and  refinement in the knowledge about the members of those –  and related – assemblages. Paradoxically, the protozoa  themselves are becoming more difficult to define with  precision as our information about them and other microbial assemblages increases. Thus, presenting a single  satisfactory circumscribed definition for them is not an  easy task.

...

Answer A sounds so funny.

Answer C and D are false because Protozoans are usually single-celled and heterotrophic.

Hope this answer can help you. Have a nice day!

If a corn plant was heterozygous for kernel color and seed shape, what would be the genotype of the plant?
NNADVOKAT [17]

Answer:

<em>The genotype of the plant will be PpSs and the phenotype will be purple colour and smooth shaped. </em>

Explanation:

Considering the description in the question, we know that purple colour is dominant over the yellow colour and smooth shape is dominant over the wrinkled shape.

A homozygous trait can be described as a trait which arises due to the same alleles of a gene. A heterozygous trait arises when both the alleles of a gene are different. In such a case, one allele will be dominant over the other one and the phenotype of the dominant allele will be seen in the plant. As purple colour and smooth shape are dominant traits, hence they will be seen in the heterozygous plant.
