The correct answer is: 2.5%
The vast majority of the human genome (97.5%) is comprised of non-coding DNA with different functions. Non-coding DNA includes telomeres, introns, non-coding RNA genes and gene regulatory sequences.
• Telomeres-ends of DNA with protective role (prevents shortening of DNA),
• Non-coding RNA genes-e.g. genes for tRNA,
• Gene regulatory sequences such as promoter, enhancers and silencers.
Answer:
ATP acts as a regulatory molecule in multiple steps of the citric acid cycle:
- An abundance of ATP inhibits the <em>pyruvate dehydrogenase</em> complex that converts pyruvate into Acetyl Co-A.
- ATP acts as an inhibitor for the enzymes, <em>isocitrate dehydrogenase</em> and <em>α-ketoglutarate dehydrogenase</em>.
- In bacteria, ATP is an allosteric inhibitor of the enzyme, citrate synthase.
Explanation:
In the citric acid cycle, the 2 pyruvate molecules formed can either be converted to Acetyl Co-A or stored as lipids. As the enzyme, pyruvate dehydrogenase has to make this decision, this step of the TCA cycle is a crucial control point of the pathway. Pyruvate dehydrogenase is activated when phophorylated by a kinase but deactivated in the presence of high amount of ATP by a phosphatase enzyme. On the contrary, the presence of high ADP activates the complex.
ADP or a low energy signal allosterically activates the <em>isocitrate dehydrogenase</em> that converts isocitrate to a five carbon alpha-ketoglutarate. High ATP inhibits the enzyme.
The enzyme, <em>α-ketoglutarate dehydrogenase</em><em> converts a</em>lpha ketoglutarate to a four carbon compound, succinyl Co-A. Here, ATP also acts as an inhibitor.
Answer: all eukaryotes
Explanation: Plants and animals both preform cellular respiration. Cellular respiration is the process of sugar (glucose) being in the process of transforming into energy for the cells!
Answer: The dolphin's population growth is 150% .
Explanation:
The birth rate of dolphins = ![2.0=\frac{2.0\times 100}{100}=200\%](https://tex.z-dn.net/?f=2.0%3D%5Cfrac%7B2.0%5Ctimes%20100%7D%7B100%7D%3D200%5C%25)
The death rate of the dolphins = ![0.5=\frac{0.5\times 100}{100}=50\%](https://tex.z-dn.net/?f=0.5%3D%5Cfrac%7B0.5%5Ctimes%20100%7D%7B100%7D%3D50%5C%25)
Dolphin's population growth = Birth rate - Death rate
= ![200\%-50\%=150\%](https://tex.z-dn.net/?f=200%5C%25-50%5C%25%3D150%5C%25)
The dolphin's population growth is 150%.
I think the correct answer would be the third option. Environmental influences include family dynamics, neighborhood quality, and educational opportunities. These influences involve everything that surrounds an individual. The environment one is subjected to greatly affects the totality of that person may it be psychological, social, physical, behavior or attitude, beliefs and perception. For instance, if a child grow up in an environment that is healthy where relationships are nurtured and love and respect is present between members, then most likely this child would grow with great self esteem and would have the same characteristics as the people he lived with.
