Answer:
Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner. Effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves. Scientists have high confidence that global temperatures will continue to rise for decades to come, largely due to greenhouse gases produced by human activities. The Intergovernmental Panel on Climate Change (IPCC), which includes more than 1,300 scientists from the United States and other countries, forecasts a temperature rise of 2.5 to 10 degrees Fahrenheit over the next century.
Explanation:
does this work :)
An enzyme is protein and it needs to maintain its 3D structure as the enzyme work like "lock and key". A little deformation to the enzyme structure can disable its functions.
Protein is prone to denaturation. Condition like pH and temperature can affect the protein and cause an alteration to its structure. Higher temperature should speed up the reaction but too high temperature might damage the enzyme. So, the "optimal" condition would be the condition where the enzyme structure is not altered.
Answer: The claim that gene regulation results in differential gene expression and influences cellular products (albumin or crystalline) is best supported by t<u>he specific transcription factors made in a cell.</u>
Explanation:
Genes store deoxyribonucleic acid or DNA that makes up the genome. The genetic information within genes is expressed through a process called transcription followed by translation.
During this, the genotype of the organism is changed into its phenotype or physical characteristics genes are controlled or regulated through certain molecular mechanisms These essentially determine transcription and translation and whether gene products is active or in active genes are turned on when they are able to transcribe the genome.
gene expression may be regulated
via
- modulation before or after the transcription process
- modulating translation
- modulation after translation
A control for the transcription process is called a transcription factor. These are DNA sequence specific proteins that are capable of activating or suppressing transcription at certain sites. In different cell types, different combinations of transcription factors contribute to gene expression.
The correct answer is b. The kingdom classification system can change based on the discovery of new information and organisms.
<span>
The kingdom is taxonomic rank, below domain which is divided into smaller groups called phyla. Different kinds of proposed classification changed over time and at the moment the kingdom-level classification of life includes Bacteria, Archea, Protozoa, Chromista, Plantae, Fungi and Animalia.</span>
