Unoxygenated blood from veins enters the right atrium then it goes down to the right ventricle then out through the pulmonary artery to the lungs where it becomes oxygenated blood which then enters the heart through the pulmonary veins and it goes to the left atrium and then is pumped down to the left ventricle and out through the aorta to the arteries where it travels to different organs and becomes deoxygenated and then the cycle repeats itself.

Place the following steps of endomembrane system function in the correct order.
maks197457 [2]

Answer:

D

Explanation:

<em>The correct option here would be</em><em> D</em><em>.</em>

The endomembrane system refers to a group of membrane-based organelles whose primary function is to synergistically work together to modify, package, and transport lipids and proteins. The system includes organelles such as the lysosome, the nuclear envelope, the endoplasmic reticulum, and the Golgi apparatus.

For an endomembrane system function involving a protein, the protein would first of all need to be synthesized by the ribosome - the free ones or the ones attached to the rough endoplasmic reticulum. Thereafter, the synthesized protein would then be folded or packaged into transportable vesicles. The vesicles are then received by the Golgi apparatus which further modifies the proteins before transporting them accordingly.

Hence, the correct order of a typical endomembrane system function would be:

  1. <em>Ribosomes on the RER synthesize proteins.</em>
  2. <em>Proteins are packaged into transport vesicles.</em>
  3. <em>Golgi apparatus receives transport vesicles from the RER.</em>
  4. <em>Proteins are modified by the Golgi apparatus.</em>
  5. <em>Modified proteins may be secreted from the cell by exocytosis.</em>

Which situation would most likely increase the carrying capacity for humans
vredina [299]

C. A new source of freshwater

Explanation:

The situation that would most likely increase the carrying capacity for humans in a certain region is the availability of new sources of freshwater.

In ecological terms, the carrying capacity of a place is the the number of people, animals, or crops which a region can support without environmental degradation.

  • A new source of freshwater provides new resources for the ecosystem.
  • In the freshwater, more fishes are available, more plants can grow around and a lot of biological activities can progress.
  • Water is essential for life.
  • Fresh water sources are incentives for choosing to live in a place or not.
  • A fresh water source increases the carrying capacity for humans in a certain region.

Which statement is true about atoms that are more stable?
Svetlanka [38]
The stability of atoms depends on whether or not their outer-most shell is filled with electrons.  If the outer shell is filled, the atom is stable.  Atoms with unfilled outer shells are unstable, and will usually form chemical bonds with other atoms to achieve stability.
