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.
Answer:
1. E. A, B, and C
2. B. Smooth ER
3. D. Neither
4. B. Maintains turgor pressure in plants
Explanation:
1. Though I've never heard of "nuclear pores" in the nucleus (I've only known of them to be in the nuclear envelope), answer E is the only one that has the most obvious answer--storing genetic material. The nucleus regulates cell activities by using the stored genetic material to produce proteins.
2. There's no explanation for this as it's pretty much just memorizing the function of organelles, just remember that "lipid biosynthesis" is just basically saying "making lipids".
3. Viruses are neither eukaryotic or prokaryotic since they have no defining characteristics that eukaryotic and prokaryotic cells have. They lack a nucleus and can only replicate when inside a host cell.
4. The words "large central vacuole" should give you a big hint to the question talking about a plant cell. Turgor pressure is when the cell walls of plant cells press up against each other due to the size of the large central vacuole. This is why plants wilt when they do not have enough water, their cell walls do not press against each other so the structure is weak.
Almost positive diagram A is a animal cell that’s eukaryotic, and Diagram B is a plant cell that’s also eukaryotic.
