My guess is that you're wanting the formula for respiration (which is basically the opposite of the formula for photosynthesis)?
So on the left (reactant/inputs) side should be: sugar and oxygen
On the right (products/outputs) side should be:
Carbon dioxide, water, light energy/ATP
The correct answers are:
- Methylation of histone tails in chromatin can promote condensation of the chromatin.
- DNA is not transcribed when chromatin is packaged tightly in a condensed form.
- Acetylation of histone tails is a reversible process.
- Some forms of chromatin modification can be passed on to future generations of cells.
- Acetylation of histone tails in chromatin allows access to DNA for transcription.
Histone modifications are post-translational modifications of histone protein that can affect gene expression by altering chromatin structure or recruiting histone modifiers.The most common modifications are methylation, phosphorylation, acetylation and ubiquitylation. All of them affect the binding affinity between histones and DNA and thus loosening (gene activation) or tightening (gene repression) the condensed DNA.
Histone methylation is a transfer of methyl group by histone methyltransferases to lysine or arginine amino acid of protein. Effect of methylation depends on the type of protein that is modified. Demethylation is the reverse process.
Histone acetylation is the process of adding of an acetyl group(by histone acetyltransferases) to histone proteins and it can also activate or inhibit the gene expression. Deacetilation is reverse process.
Answer:
I think its chemical energy is not required because passive transport doesn't need energy at all
Answer:
A) drive reduction
Explanation:
Motivation is the urge that fuels and directs human with the energy to accomplish a given task. Motivational theory is accustomed with the role of searching for what drives individuals to work towards a goal or a task.
The drive reduction theory explains physiological ideology required bring out an aroused tension state that motivates an organism to satisfy the need.
Instincts Theory reflects innate and fixed pattern of complex behavior in animals. For example, making holes of crabs for safety.
Optimum Arousal Theory drive people to engage in certain activities in the quest to keep up with an optimum level of physiological arousal.
Hierarchy of motives: According to Maslow's pyramid, hierarchy of motives is explained based on need to satiate or quench the least physiological needs in order to be active before subsequent level needs.
Answer:
Although you might have heard people talk about a gene for red hair, green eyes or other characteristics, it's important to remember that genes code for proteins, not traits. While your genetic makeup does indeed determine physical traits like eye color, hair color and so forth, your genes affect these traits indirectly by way of the proteins created via DNA.
Hopefully, this answer helped! :D
