Biuret solution is used to identify the presence of protein. Biuret reagent is a blue solution that, when it reacts with protein, will change color to pink-purple. Sugar with Benedict's solution. Protein with Biuret solution.Aug 10, 2020
Answer: population of bacteria can survive and flourish by using light independence reactions
Explanation: So like the bacteria perform chemical reactions which produce energy for them
Answer:
The correct option is b) motor output of the spinal cord
Explanation:
Motor neurons, also called afferent neurons, drive impulses from the brain and spinal cord to the receptors (eg, muscles). They are the motor output component of the spinal cord.
The spinal cord is a cord of nerve tissue that runs inside the spine. It conducts the nerve impulses that arrive from the receptors to the brain, and the responses with the motor orders from the brain to the effector organs. Thus, the brain receives the information and can develop an order that modifies the reflex response given by the spinal cord. A spinal nerve has two nerve roots: a motor and a sensory root. The motor root has nerve fibers that carry signals from the spinal cord, to the muscles to stimulate contraction and produce muscle movements, the fibers are efferent as they leave the medulla to the periphery through the anterior roots of the spinal nerves.
Answer: • Most prokaryotes lack well-defined organelles. They can move from one place to another using cilia.
• The presence of peptidoglycan in their cell walls allows them to be visible on staining.
Explanation:
A prokaryote lacks a nucleus that's enveloped enclosed. Also, most of them doesn't have well-defined organelles.
The presence of peptidoglycan in their cell walls allows them to be visible on staining and they can move by using cilia.
Answer:
It could happen through mutation
Explanation:
<em>A segment of DNA after many cell divisions could have more base pairs than it originally did as a result of mutation.</em>
Mutation is generally defined as a sudden change to the DNA sequence of a cell. This change could be of difference forms, including:
- <em>Addition of bases</em>
- <em>Deletion of bases</em>
- <em>Substitution of bases</em>
<u>Addition of bases to a DNA will generally lead to a longer base pairs in the DNA, deletion will lead to a shorter base pairs while substitution will only lead to a change in the base sequence without any change in the length of the DNA.</u>
