<span>Transfer of materials into a cell against a concentration gradient from low to high concentration requires active transport because you need energy for it to happen since its going againist the concentration gradient.

2) If the foliation on a rock is running north-south what direction is the tectonic pressure coming from?
vovangra [49]

Answer:

if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down)

Explanation:

The pressure is the second most principal factor that influences metamorphic rocks. It originates from the weight of the own materials, their densities, and the deepness.  

Litostatic pressure originates from the weight of materials in the interior of the crust.

Pressure generates alignment of materials (foliation and schistosity) and mineral rotation.

There are different types of metamorphism.

Dynamic metamorphism is the one where pressure is the principal factor. It generates by tectonic conditions, and it presents mainly in failure or fracture areas. It provokes trituration and recrystallization of minerals.

Classification of the metamorphic rocks according to their structure:

  • Granulation
  • Recrystallization
  • Metasomatism
  • Massive
  • Foliation

Foliation refers to dynamic metamorphism, where pressures act and minerals orientate perpendicular to the pressure direction.

<em>According to this concept, if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down) while minerals' weight helping in the process of foliation. </em>

Do you think microscopic organisms like bacteria and amoebas are impacted differently by the factors that limit population size
yarga [219]

Answer:

Explanation:

Factors that limit population size of an organism and slows it down and prevents it from growing are called limiting factors. Limiting factors generally affects all living organisms with the same impact; this is because the mode of survival of living organisms (based on the characteristics of living things) are usually threatened by limiting factors BUT the responses are different.

For example, when there is low supply of food (which is a limiting factor), large organisms (like humans) emigrate from such region or location to a region where there is a large or enough supply of food thereby reducing the population of the that large organisms in the initial location. A short supply of food/nutrient for bacteria (which is also a limiting factor) is responded to differently. When there is a short supply of nutrient to a bacterial population, it affects the population size by restricting the growth of such bacteria in that space/location.

jekas [21]
C) Both.
Plants go through photosynthesis (producing Oxygen), but to consume the sugars they have created they have to go through cellular respiration as well, which produces carbon dioxide. All organisms go through cellular respiration.

Hope this helps! :)
