Answer:
carbohydrate chain
Explanation:
Cholesterol is more rigid than some of the other lipids in the membrane. Cholesterol keeps the fatty-acid tails of the phospholipids bilayer from sticking together, which contributes to the fluidity of the plasma membrane. The membrane would become rigid. Transport protein move needed substances or waste materials through the plasma membrane
. Carbohydrate defines the cell characteristics and help cells identify chemical signals.
Answer:
4. metabolism, growth, and evolution
Explanation:
Living organisms show different characteristics like respiration, movement, metabolism, growth, evolution, respiration, excretion, nutrition. Most of the microbes are microscopic and unicellular which means they are made up of only one cell but they are also living.
They perform three major types of activities like metabolism, growth, and evolution. This can be seen by culturing bacteria on suitable media. So in the medium, it can be observed that they consume the food present in media and extract energy from it through metabolic activities and are showing growth. All micro-organisms evolve due to mutation. So the correct answer is 4.
Answer:
An Enhancer
Explanation:
Enhancers are the regulatory sequences and are generally located 80-160 base pairs upstream of the transcription start site. Enhancers have bidirectional elements that are involved in the initiation of transcription. Enhancers serve as the binding sites for activators to increase the concentration of activators in the vicinity of the promoter and thereby increase the rate of transcription of the gene.
According to the given information, the loss of a regulatory sequence led to a reduced level of transcription of the gene. This means that the regulatory sequence was involved in the upregulation of transcription. The presence of the sequence far away from the promoter makes it an enhancer.
I love finding Nemo but I think Nemo doesn’t exist and his dad is just so paranoid so he still thinks he’s alive but no and dori don’t got memory loss she just can’t see Nemo so she forgets what they are looking for
