The absence of a particular trait does not exclude a species from a particular clade that possesses that trait because physical attributes of the species is not the basis of the groupings in the clade.

Cladistic groupings uses the evolutionary relationships among the species as its basis in grouping rather than its shared physical traits. These evolutionary relationships are called apomorphies or a set of unique features shared by all organisms in the group but not found in the distant ancestors.

What does a single-celled prokaryote, like a bacteria, have in common with a single-celled eukaryote, like an amoeba? Select the

densk [106]

Answer: Both are single-celled microorganisms which contains plasma membranes, cytoplasm, ribosomes, DNA

Explanation:

Cells are the smallest functional unit of organisms which are classified under two main categories namely:

--> prokaryotic cells and

--> eukaryotic cells.

Prokaryotes are unicellular or single-celled organisms which do not possess true nuclei. Their cell structure is simple as there is NO definite nucleus and the chromosomes lie free in a particular part of the cell. Examples of organisms that belongs to this group are the bacteria. They can only be seen through a high power of a light microscope and are found in air, water, soil and living organisms. The general structure of prokaryotes like bacteria contains Chromosome ( single DNA strand coiled up), cytoplasm, ribosome which are few cell components among others.

Eukaryotes are organisms which possess a definite or true nuclei. The cell structure is complex and highly organized with a well-defined nucleus (meaning its DNA is surrounded by a membrane). Many structures called the cell organelles are present which include: mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and lysosomes with other cell components, that is the cytoplasm, plasma membrane and ribosomes. Each organelle carries out a certain type of work. Examples of organisms that belongs to this group are the amoebas.

From the explanation above, both bacteria and amoeba are single- celled organisms which contains plasma membranes, cytoplasm, ribosomes, and DNA.

The degree to which the findings of a study may be applied to a larger population represents how ___________ a sample is. A. Ina

g100num [7]

Answer:

B. Generalizable

Explanation:

Generalizable means something's ability to be applied to a general or wide group. So, if something is generalizable that means that it is applicable to a wide group of things outside of the initial study. Thus, B is the correct answer because it is the only vocab word that properly describes how widely applicable the study is.

One of the best ways to generalize a study is to use random or probability sampling. This helps ensure that the findings of the study can be used by others in different situations.

Do unicellular organisms evolve?

givi [52]

Answer:

Unicellular organisms may stay as one cell but they grow too. Multicellular organisms add more and more cells to form more tissues and organs as they grow. ... Growth is the increase in size and mass of that organism. Development involves the transformation of the organism as it goes through the growth process.

Explanation:

Yes they can
