Answer:
1. d. changes in the methylation patterns of <em>loci</em> involved in growth and metabolic disease
2. b. differences in the expression of metabolic genes
d. changes in histone acetylation patterns
Explanation:
Epigenetics refers to the study of heritable changes in gene expression which are not dependent on DNA sequence. Epigenetic mechanisms involve DNA methylation, histone modifications (acetylation, methylation, phosphorylation, etc) and regulatory non-coding RNA (ncRNA) pathways. These epigenetic mechanisms work together and mutually reinforce each other in order to modulate gene expression (either by activating or suppressing gene expression). In consequence, transcriptome data (e.g., genes differentially expressed in particular tissues/cells or stages of development) is an important piece of evidence indicating the existence of epigenetic modulation.
Answer:
The conversion of ADP to ATP using light energy
Explanation:
Photophosphorylation is a stage in photosynthesis in which ADP is converted to ATP using sunlight energy.
Note that, in photophosphorylation, 2 ATPs are produced
This process is fundamental in maintaining a stable energy level in our eco-system.
Answer: I don't have a definitive answer for this question but I do have a helpful explanation.
Explanation: Try to find out what each letter means and organize the elements by how they connect to each other. If you don't know you can research to find a diagram that can help show you how to connect these functional elements. You could try searching how do you find the elements of HOH in a diagram.
Answer:
All options are correct, that is, they would all be correct for osteoarthritis.
This disease is characterized by being very painful at the joint level, it is degenerative, and mobility decreases over time.
Explanation:
Osteoarthritis is a pathology that is based on the fegenerative destruction of the joints, generating edema and loss of function, that is why it is pain.
The pain is very intense and very marked, that is why it is treated with immunosuppressive drugs and analgesics. (In addition to kinesiology and physiotherapy).
This disease decreases the functional unit and the joint space, generating possible ankylosis, pseudoarthrosis, elimination of lubricating fluid from joints and nodular structures. These nodular structures tend to be more common in the hands and are called by professionals as "drum fingers".
