Answer:
As a transcription factor
Explanation:
Testosterone is a male sex hormone secreted by the testicles which promote the growth of the male reproductive organs and the male characters like muscle buildup.
The hormone shows the paracrine effect and thus act on the target cell at distant. The mechanism of action of the testosterone is that it controls the gene expression of various other genes.
The testosterone binds the specific proteins which activate the expression of the gene that is they acts as a transcription factor which activates the expression.
Thus, as a transcription factor is correct.
Answer:
Rapid increases in water temperature cause extensive fish kills
Explanation:
Biotic factors are all living organisms that contribute to an ecosystem. On the other hand, abiotic factors are non-living factors, such as climatic factors (temperature, rainfall, wind), edaphic factors (soil type, soil texture, soil aeration etc). Changes of abiotic factors can have a huge influence on living organisms of ecosystem. The effects might be benefical or harmful.
Some of the most common abiotic factors that can impact a marine ecosystem are water temperature, currents, light, alkalinity, oxygent concentration etc.
The right answer is the chloroplast.
Autotrophic species must stock up on food in order to have energy at all times.
Plants, for example, through their chloroplasts make sugar with the energy of sunlight and from soil water and carbon dioxide from the air. This sugar synthesis using light is photosynthesis.
