The right answer is spiral.
Size and shape vary from one bacterium to another. The majority of bacteria have a size between 0.5-5 μm in diameter.
Most bacteria are either spherical or rod-shaped. In the first case they are called cocci (of the Greek kókkos, grain) and in the second bacilli (of Latin baculus, rod). There are also intermediate forms: coccobacilli. Some rod-shaped bacteria are slightly curved like vibrio. Other bacteria are helicoidal. They are spiral if the form is invariable and rigid, spirochaetes if the body is flexible and can change shape.

Answer:The correct answer for your question is lizards and snakes are more genetically similar than lizards and birds.
Explanation:As already known that the Order of Squamata is the largest order of reptiles but lizards and snakes alone make the largest part of the Squamata. Lizards and snakes are similar in many aspects like cold blood, senses, tongue and reproductive organs.
Answer:
The correct answer is option d. "A region of DNA sequence upstream of a gene where transcription factors bind".
Explanation:
Cis-regulatory elements (CREs) are fragments of DNA that do not encode to a protein, but regulate the transcription of nearby genes. CREs regulation is based on binding to transcription factors. These elements are vital for the regulation of complex molecular mechanisms that involve the participation of multiple genes. Additionally, CREs could participate in pleiotropy (a single gene being responsible for the development of multiple traits), because a single transcription factor could bind to different CREs.
