Answer:
Similarly to their eukaryotic counterparts, bacterial chromosomes perform the complex task of efficiently compacting DNA while supporting gene regulation and proper DNA segregation. Chromosomes are thus shaped at multiple scales by a large number of proteins and DNA enzymes
- Analyze: (f) look for relationships of data
- Scientific method: (g) series of steps to solve a problem
- Conclusion: (d) statement based on the results of the experiment.
- Constant: (b) variable that remains the same
- Scientific Law: a) well-tested description of how something works in nature.
- Research: (c) gather information using the library or internet
- Multiple trials: (e) conducting an experiment more than once
Scientific laws explain phenomena that have been proven to be true by the scientific community. In general, theories explain how a phenomenon occurs, whereas laws predict what will happen in a particular scenario based on an equation.
A scientific law foretells the outcomes of particular initial circumstances. It may tell you what color hair your unborn child would have or how far a baseball will travel when launched at a specific angle. In contrast, a theory seeks to offer the most plausible justification for why events take place the way they do.
The five most well-known scientific laws are:
- Bernoulli's law of fluid dynamics.
- Dalton's law of partial pressures.
- Hooke's law of elasticity.
- Fourier's law of heat conduction.
- Archimedes' Principle of Buoyancy.

Answer:
THE ANSWER BELOW and i really hope this is the answer your looking for if not i am sorry
Explanation:
A. Brain - Organ level
B. Neurons - Cellular level
C. Neurotransmitters - Chemical level
D. Neurons and neuroglial cells - Tissue level
E . Brain combined with the spinal cord and spinal nerves - Organ System level
There are five levels of organisation of life; cell, tissue, organ, system and organism.
The smallest unit is cell. Neurons are nerve cells.
Aggregation of cells forms a tissue. Neurons and neuroglial cells aggregate to form nervous tissues and are hence at tissue level.
Aggregation of tissues forms an organ. Brain is an example of organ. It is formed from aggregation of nervous tissues.
Tissues aggregate to form organs while aggregation of organs constitute a system. The nervous system consist of brain combined with spinal cord and spinal nerves.
The nervous system release chemicals called neurotransmitters.
The answer is chicken.
Biuret test is used to detect the presence of peptide bonds. Peptide bonds exist in proteins, so when they are present the test comes purple(positive).
Protein is found in big amouts in meat, fish and tofu.
From the options the one with the biggest amount of protein is chicken(around 33g/100g) and will cause the highest positive reaction in the biuret test.
Coconut and potato also have it, but its very little. They are rich in other macronutrients.
Cookies are full of sugar, not protein.
Butter is a source of fat, not protein.
1. The lipid would be more saturated. FALSE
2. The lipids on the fatty acid tails would be much shorter. TRUE
3. The membranes would contain more cholesterol. TRUE
<u>Explanation:</u>
The mammal caribou lives I the extremely cold environment of the Arctic and thus has several physiological adaptations to survive the cold. They have short ears to reduce heat loss and have two layers of fur. The lipids in caribou legs have several adaptations
When compared with saturated fatty acids unsaturated fatty acids are more fluid at low temperatures. Thus the lipids in the legs of caribou are unsaturated to maintain fluid nature at low temperatures of the Arctic. Shorter lipids on fatty acid tails remain more fluid at low temperatures when compared with the longer ones.
Thus the lipid in the fatty acid tails will be shorter. Similarly the presence of more cholesterol in the membranes would make it more fluid in the cold conditions of the external environment. Thus the membranes would have more cholesterol.
