Answer:chloroplasts and cellulose cell wal
Explanation:
<span>the glucose-sodium cotransporter in animals, Na+ moves back into the cell down its electrochemical gradient, providing the energy for glucose to move into the cell against its concentration gradient.
</span>It makes sense css <span> glucose is cotransported with Na+ ions</span>
<span>In cotransport, the energy required to move one solute against its concentration or electrochemical gradient is provided by an ion moving into the cell down its electrochemical gradient. </span>
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.
Answer:
The theory of aging evolution
Explanation:
The theory of aging evolution seeks to investigate the reasons why living beings begin a degeneration process at a certain age, among the various theories proposed is that of <em>Peter Brian Medawar</em> proposed in 1952, who claimed that natural selection avoided these mutations malignant <em>during the reproductive stage</em> to avoid the reduction of the population, however once this stage concluded the selection allowed them to manifest themselves.
