Exercise can cause lactic acid fermentation in the muscles
Hope I helped! :) (would you mind giving Brainliest answer? I'm trying to increase my title and I would really appreciate it!)
I believe ecosystem sorry if I'm wrong
Answer:
A) AV node
Explanation:
According to my research on studies conducted by various medical professionals, I can say that based on the information provided within the question the structure being mentioned is the AV node. The atrioventricular node is responsible for connecting the atria and ventricles transferring the depolarization wave from the atria to the ventricles.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
Answer:
This binding causes a conformational change in the receptor which enters into the nucleus and binds DNA to activate transcription
Explanation:
Testosterone is a steroid hormone responsible for inducing protein synthesis and growth of tissues with androgen receptors. Testosterone receptors, also known as androgen receptors, are a class of nuclear receptors activated by binding androgenic hormones (e.g. testosterone) in the cytoplasm, whose binding induces a conformational change of the receptors that are subsequently translocated to the nucleus. Within the cell nucleus, these activated receptors form homodimers that bind DNA in order to promote the transcription of target genes capable of regulating cell growth, cell cycle progression and survival.
When Sarah performed this experiment, she changed the levels of nitrogen in order to observe the changes in the morphological features of the plant.
All of the characteristics of the plant that she observed were dependent on multiple different things, but the level of nitrogen was an independent variable that she was changing at her will.
