The correct answer is a eukaryotic cell. The eukaryotic cell is a bacteria cell that has the same structure as more complex cells. Eukaryotic cells have many structures that help to maintain homeostasis and also to provide energy for the protein synthesis.
Answer:
The correct option is A. Steroid hormones exert their action by entering the nucleus of a cell and initiating or altering the expression of a gene.
Explanation:
Steroid hormones are derived from cholesterol and regulate multiple biological processes. All steroid hormones exert their action by crossing the plasma membrane and by binding with their respective intracellular receptors. They stimulate cell growth in a very different way, their lipophilic nature gives them the ability to cross lipid barriers, so, without the need for extracellular signals, these hormones can easily enter the cell, cross the cytoplasm and reach the nucleus. There they bind to specific receptors that are associated with DNA promoter regions, modifying their structure and promoting the expression of the genes under their control.
It depends on what the big fish and the small fish eat
Answer:
3 peaks
Explanation:
Topographic map is used to show different landforms using different symbols. There are two important elements of landforms that include elevation and slope. It uses contour lines to portray different features of lands on the map such as slope and elevation.
<em>According to topographic maps, more close are the counter lines, more elevation are in the landforms. </em>
Peak is the pointed top of mountains. In this topographic maps peaks or elevation is shown in the form of irregular spherical shape. There are 4 elevations in the map but only 3 shows the peak according to counter line formation and the fourth elevation will not have peak on the top.
Hence, the given topographic map has only 3 peaks in the landform.
