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:
from precipitation, oceans lakes streams and soil
Deforestation is the most serious problem facing the world’s forests and the main regions of forest loss are Amazon rain forest.
Deforestation refers back to the decrease in wooded area areas internationally which are misplaced for different uses such as agricultural croplands, urbanization, or mining sports. significantly accelerated by means of human sports due to the fact that 1960, deforestation has been negatively affecting natural ecosystems, biodiversity, and the climate
If forests are cleared, or even disturbed, they release carbon dioxide and different greenhouse gases. forest loss and harm is the cause of around 10% of worldwide warming. there may be definitely no manner we can fight the climate crisis if we do not prevent deforestation.
Forest loss captures essential influences on woodland cover: deforestation and forest degradation. Deforestation is the whole removal of bushes for the conversion of wooded area to every other land use inclusive of agriculture, mining, or cities and towns.

Answer:
The correct answer is B. <em>The cells in the outer skin surface appeared flat, whereas the cells in the cross section were not flat.</em>
Explanation:
The epidermis is made up of five cell layers, which have different functions: Stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.
- <u><em>Stratum basale</em></u> is the <em>innermost germinative, single, basal layer of the epidermis </em>composed of basal cuboidal-shaped cells. These cells are the precursor of keratinocytes, this is why this layer is also called germinativum. In this basal layer, there are also Merkel cells as well as melanocytes.
- <em><u>Stratum spinosum</u></em> refers to the keratinocytes which produce keratin.
- <u><em>Stratum granulosum</em></u>, this is the layer where keratinization begins. Cells produce hard granules that change to keratin and lipids as they ascend.
- <u><em>Stratum lucidum</em></u> is conformed of densely compressed cells, which begins to flatten and appear indistinguishable between each other.
- <u><em>Stratum corneum</em></u> is the most external layer, composed of dead, flattened cells which are released regularly in a process known as desquamation.
