Answer:

So where then did all the carbon that living organisms are built of come from? It turns out that most of the carbon we use today came from a collision with another smallish planet about 4.4 billion years ago.

IN THE LUMEN INSIDE OF THE ENDOPLASMIC RECTICULUM.

<u>Explanation:</u>

The endoplasmic recticulum is the continuous membrane system that forms that forms the more number of flattened within the cytoplasm of eukaryotic cells and performs the multiple process in the cell.

The immportant functions of endoplasmic recticulum is folding, synthesis, modification, ans transport of the protein. The lumen is the protein which is present in the endoplasmic recticulum.

The lumen of the endoplasmic recticulum is the area closed by the endoplasmic recticulum membrane, it is an extensive network of the membrane tubues, visicles, and flattened the cisternae found in the eukaryotic cells.

What most likely happens when lithospheric plates move apart deep below the ocean?
Alisiya [41]

Magma seeps up along plate boundaries and forms mountains.

Factor 1 creates competition and factor 2 creates genetic variation.

Explanation:

Question 1: Magma seeps up along plate boundaries and forms mountains.

When lithospheric plates move apart they create divergent plate margin where magma seeps up along the plate boundary and forms series of mountains. The mid oceanic ridge was formed this way.

  • The lithosphere lies on the weak and molten asthenosphere.
  • Different plate interactions produces a wide range of plate movement.
  • Along a divergent margin usually, two oceanic plates are forced to move apart.
  • The forces the asthenosphere to rise through seeps as magmatic bodies.
  • The rising magma them crystallizes along the margins of the plate to form mountain chains like the mid-oceanic ridge.
  • It is common to find young rocks at the plate margin and the older ones away from spreading centers.

Question 2: Factor 1 creates competition and factor 2 creates genetic variation.

Scarcity of space leads to competition between organisms and availability of mates creates genetic variations.

  • In an ecosystem with limited space, there will pressure on available resources.
  • This will lead to different organism developing strategies to efficiently adapt to their environment.
  • Organisms will in turn begin to compete with one another for the limited resources.

When we have a diverse number of mating options, genetic variation occurs. This suggests that we can have different gene combination as a result of the mating organisms.

A variation in the genetic pool of a place leads to better adaptable traits to survive the environment.

Why is it necessary to fertilize agricultural crops to improve productivity?
sattari [20]

Answer:

  • Because soil has lost nutrients.
  • To provide the right nutrients needed by a particular plant to grow.

Explanation:

Due to regulkar use of soil, the nutrients in the soil have been constantly used by the plants grown on it.

Due to this, soil has lost its value.

Application of fertilizer is one wey through which farmers artificially provide nutrients to the soil.

Therefore, application of fertilizers becomes neccessary for improved crop productivity.
