Hello!
Higher temperature affects plants’ growth especially in temperate crops like wheat. It reduces the growth of shoots and roots in plants. This, in turn, results in a substantial reduction in the overall height of the plant. High air temperature can lead to dehydration and scorched leaves.
In general, the increase of temperature would cause a damage in ecology of a certain area as most plants would not be able to adapt to this change. This, in turn, will affect the distribution of such plant species as they would die off unless placed in an environment with more favorable conditions.
The answer is asexual reproduction. This type of reproduction does not involve fusion of gametes. The offspring arise from a single organism and inherit the genes of that parent only. Consequently, there is little variation from parent compared to sexual reproduction.
Steroid hormone
- The cell signaling pathways induced by the steroid hormones regulate specific genes within the cell's DNA. The hormones and receptor complex act as transcription regulators by increasing or decreasing the synthesis of mRNA molecules from specific genes.
- Steroid hormones are not able to target every cell within the body, so the overall response is slower. They bind to receptors on the cell's surface and the receptors aid in helping the steroid hormones enter the cell.
- Hormones work by binding to protein receptors either inside target cells or on their plasma membranes. The binding of a steroid hormone forms a hormone-receptor complex that affects gene expression in the nucleus of the target cell.
- Steroids pass into a cell's nucleus, bind to specific receptors and genes and trigger the cell to make proteins.
