10. Which of the following groups of organisms are prokaryotic? (Choose all that apply)
Archaea
Or
Plants
Or bacteria
Or fungi

Answers

Answer:

Archaea bacteria

Explanation:

just search each answer choice asking if its eukaryotic or prokaryotic and it will tell you

Bacteria and Archaea are groups of organisms that are prokaryotic, which means that their cells do not have cellular organelles or a delimited nucleus in the cytoplasm.

The prokaryotic cell is characterized by not having a cell nucleus, therefore its ribosomes are smaller and its genetic material simpler.

Prokaryotes are, in most cases, unicellular microorganisms.

The bacteria is a unicellular and prokaryotic microorganism, which means that it does not have a nucleus, they are a few micrometers long and various shapes including spheres (cocci), rods (bacilli) and helices (spirils).

A diversity of unicellular microorganisms that make up the archaea kingdom lacking nuclei (prokaryotes) is known as archaea.

Their cells are surrounded by a covering (cell wall) made of various materials that give them high resistance against antibiotics or other harmful substances.

Therefore, we can conclude that bacteria and archaea are groups of organisms that are prokaryotic, which do not have a defined nucleus and or organelles surrounded by a membrane.

Identify the strengths and weaknesses of Mendel’s Law of Independent Assortment.

Answers

Answer:

Explanation:

Mendel propel two laws The law of inheritance and that of independent assortment of gene.

Independent assortment of gene explain that alleles of a gene assort independently and that different Allele can show different phenotypic effect and differences. This means that in a gene where we have 2 allele they can both show individual difference where one can have a dominant effect over the other and the other allele is recessive.

This law does not take care of linked gene where alleles don't separate after crossing over sister chromatids but are rather inherited together given rise to complex inheritance.

Monetary policy is supposed to be (independent of/coordinated with) Congress and the president. This goal is aided by the fact that the governors' (two years term dont allow/ 14 year terms allow) them to outlast the president who appointed them. Because Congress initially intended to create a decentralized banking system, there are also smaller branches of the Federal Reserve known as district banks. The presidents of the district banks take turns serving as members of the (board of goverment/ federal open market committee) The Federal Open Market Committee (FOMC) is the official policymaking body of the Federal Reserve and is made up of (all board governors and five bank presidents/ all bank presidents and five board governors/ memebers of the board of governors/ distrtct bank presidents) . The mechanism for translating FOMC policy into action is (the federal funds rate/the reserve requirement/ the statement of open-market operations/ an FOMC directive) , which outlines the course of monetary policy for the next six weeks.
