The muscular system can be broken down into three types of muscles: skeletal, smooth and cardiac, according to the NIH. Skeletal muscles are the only voluntary muscle tissue in the human body and control every action that a person consciously performs. The muscle that is found at the heart is Cardiac Muscle.  It is an involuntary, striated muscle that constitutes the main tissue of the walls of the heart. Hope this helps.

kati45 [8]

A hypothesis for this observation might be that malaria is not endemic to southern Africa. It is a plausible explanation of a given scientific question.

<h3>Hypothesis and scientific method</h3>

A hypothesis is a plausible explanation of an observation of the natural world, which must be tested by using the scientific method.

Testing a hypothesis involves performing additional observational and/or experimental procedures in order to confirm or reject this assumption.

In this case, the sickle cell allele is found in high frequency in regions where malaria is endemic.

A plasmid _____________________________ . A. can confer antibiotic resistance to a bacterium. B. is a single-stranded circular D
hodyreva [135]

Answer:

The correct answer will be option A.

Explanation:

The bacteria organize its genetic material in the single circular chromosome suspended in the cytosol along with additional circular double-stranded DNA molecule called plasmid.

The plasmid is present as a separate structure in the cytoplasm which performs important functions during stressful conditions in the bacteria like providing antibiotic resistance to the bacteria, formation of filial factors during conjugation and many others.

The plasmid which confers resistant to the bacteria is known as the R-plasmid. The R-plasmid consists of r-determinants which confers antibiotic resistance to the bacteria and resistance transfer factor (RTF) which helps in plasmid transfer.

Thus, option A is the correct answer.
