Answer;
Decision making and emotion; memory and visual processing
Explanation;
Cingulate Cortex is a subcortical structure above the corpus callosum. its anterior (Forward) segment participates in decision making and emotion, and its posterior (rear) segment participates in memory and visual processing.
-The forward 2/3 of this structure, the ACC: anterior cingulate cortex- participates along with the hypothalamus in the control of the autonomic nervous system (also roles in decision making, emotion, anticipation of reward, and empathy)
The rear third, PCC: Posterior cingulate cortex participates in memory and visual processing.
Answer:
The correct order, from fastest to slowest, for the passage of molecules and ions through the cell membrane is oxygen, sodium ions, glucose (option D).
Explanation:
The plasma membrane is a lipid bilayer, with glycoproteins and membrane proteins, which constitutes a semi-permeable barrier to the passage of substances into and out of the cell.
The speed with which a substance can pass through the membrane depends on its chemical properties -hydrophilic substances pass through with greater difficulty than lipophilic ones- requiring in some cases specialized transport mechanisms. The different rates with which a substance passes depends on this.
- <em>Oxygen (O₂) </em><em>passes through simple diffusion, depending on a concentration gradient. It's the molecule that passes through the membrane the fastest.
</em>
- <em>In second place, there would be the </em><em>Na⁺ ions</em><em> -charged atoms- that cross the membrane by facilitated diffusion, through specific ionic channels.
</em>
- <em>The </em><em>glucose</em><em> molecule, being larger, requires the use of transport proteins, being its passage through the membrane slower with respect to oxygen or sodium.</em>
Undoubtedly, molecular weight and affinity for the plasma membrane are determining factors for the passage of molecules through the lipid bilayer.

Answer:1) Carbon moves from atmosphere to hydrosphere and biosphere in the process of photosynthesis and to lithosphere by deposition of dead bodies while from hydrosphere and biosphere, carbon can be move in the process of respiration by animals.
2) During respiration process which takes place in plants in which carbondioxide is released and by eating carbon containing food by animals. By decomposing the food, carbon is releases in the form of carbondioxide.
3) Carbon can be used by the marine plants in the process of photosynthesis and during the process of diffusion, carbon is also dissolve in water bodies.
4) When the plants and animals die, the carbon which is present inside their body is buried in the soil present at the bottom of the ocean and the shells and corels of some animals also contain carbon which is soon be the part of the lithosphere when they die.
5) After the decomposition of seashell, carbondioxide is produced because shells are made up of calcium carbonate.
Explanation:
Explanation:
In simple diffusion, small molecules without charges such as oxygen and carbon dioxide flow through a plasma membrane without assistance and without expending energy. Other substances such as proteins, glucose and charged particles called ions cannot pass through the selectively permeable membrane
