in question number 6, the correct answer is false. this is because arrow  C is representing a combustion reaction whereby hydrocarbon or organic carbon from the fossil fuel is burnt in the presence of oxygen to produce carbon dioxide. this process is not conversion of chemical energy to mechanical energy. in this process energy will still be stored in form of chemical energy in the bonds of carbon dioxide and water produce


in the question number 7 the correct answer is true.  this is because the green plant is using energy from the such for the process of photosynthesis. photosynthesis is a process by which green plants make their own food using energy from the light. light energy is used to split the molecules of water to oxygen and hydrogen ions. oxygen is released into the atmosphere whereas hydrogen ions are used in the dark stage of photosynthesis a process referred to as carbon fixation. the end result of carbon fixation is production of organic compounds such as glucose, protein and lipids among others. these foods store energy in form of chemical energy. so arrow A represents transfer of solar energy to chemical energy


in the question number 8, the arrows that represent the release of carbon dioxide include arrow C and arrow F. in arrow C the process occurring is referred to as combustion and it occurs when hydrocarbon in fossil fuels reaction with oxygen in the presence of heat to produce carbon dioxide and water. the arrow F represents respiration, a process by which living cells manufacture energy in form of ATP from organic food such as glucose. respiration end products include water carbon dioxide and ATP. it is essentially the reverse of photosynthesis


in question number 9, arrow E represents cycling of carbon from living organisms to non-living organisms. this is because it is showing conversion of a carbon from the dead tree to fossil fuel. when plants and animals die and buried deep in the ground, they are slowly converted to fossil fuels which contain organic hydrocarbon compounds including petrol, kerosene and other compounds.


in question number 10, arrow B & C show the conservation of energy and mass. when living organisms die they are converted to fossil fuels which are used in industries to produce energy required for various activities. during this process carbon dioxide is released into the atmosphere and it is used by plants in the process of photosynthesis as shown by B. this is conservation of energy and mass the number of carbon in the fossils fuel initially came from living plants and when fossil fuel is combusted it produces carbon dioxide that will be used in the process of photosynthesis and cycle continues.

If your blood sugar level is low from skipping lunch what reaction will occur in your liver cells
Vadim26 [7]
The answer is Glycogenolysis

When we are hungry or skipped a meal our  glucagon, <span>an hormones</span> that regulates blood-sugar levels, is released to avoid glucose levels in the blood to decrease to a risky value.

Glucagon makes the liver, but also the muscle, to breakdown accumulated glucose called glycogen into glucose to increase blood-sugar levels. This process is called Glycogenolysis and can also be  stimulated by an increase in epinephrine during  fight-or-flight responses.

hodyreva [135]
<span>Parents can pass on chromosomes to their children that are different than their own when the new gene combinations are created by crossing over. The exchange of genetic material between homologous chromosomes is known as crossing over which occurs in meiosis. When homologous chromosomes pair up and exchange different segments of the genetic material. As the result, a new combination of genes will be formed. If there was not crossing over, all genes on a chromosome would be inherited together.</span>

Is the binding of a transcription factor to its dna recognition sequence necessary and sufficient for an initiation of transcrip
hram777 [196]

Transcription factors are necessary for an initiation of transcription at a regulated gene but not sufficient.

Transcription is the first step of gene expression in which DNA molecule is copied (transcribed) into RNA (mRNA) by RNA polymerase. The process of transcription is divided into three phases:

1. Initiation

• RNA polymerase with transcriptional factors bind to gene promoter Transcription factors can enhance the interaction between RNA polymerase and a DNA sequence- promoter, encouraging the expression of the gene. Such transcription factors are called activators. Otherwise, when the gene expression is inhibited, factors are called repressors and they bind to sequence –operator.

• RNA polymerase unwinds DNA double helix (transcription bubble is formed)

2. Elongation

• RNA polymerases adds nucleotides complementary to DNA  

3. Termination

• RNA polymerase gets to stop codon (transcribes a sequence of DNA known as a terminator)

• Formed complementary RNA strand is released from DNA-RNA complex
