B) It is a fluid mosaic model, with proteins interspaced in the phospholipids, both of which can freely move laterally.
Explanation:
The fluid mosaic model proposed by Singer and Nicolson describes the plasma membrane’s structure as a mosaic pattern of components consisting of phospholipids, proteins, cholesterol, and carbohydrates; all of which provides the unique fluid character of the membrane.
According to this model, the phospholipids constitute the main fabric, cholesterol attaches between the phospholipids in between the layers, integral proteins embedded within the bilayers of the phospholipids, peripheral proteins along the peripheries of the layers and carbohydrates outside the membranous layers.
Answer:
FRONTAL LOBE
Explanation:
The frontal lobe can be located at the anterior part of the brain, extending back to a fissure known as the central sulcus. The frontal lobe functions and helps in coordination of reasoning, motor control, emotion, and language. It contains the motor cortex, which is involved in planning and coordinating movement; the prefrontal cortex, which is responsible for higher-level cognitive functioning; and Broca’s area, which is essential for language production.
Let say for example Kyle is my friend who was a victim of an accident.
Before the accident, he was industrious and well liked BUT after the accident, he is profane, impetuous, and incapable of working toward a goal.
Such changes in personality would be consistent with loss of impulse control which is a significant frontal lobe function. With connections between the planning functions of the frontal lobe and the emotional processes of the limbic system severed, Kyle had difficulty controlling his emotional impulses, attitudes and abiiity of working towards his goals.
Answer: Antipararell strands
Explanation:
The feature of the DNA is antipararell strands
Continuous and discontinuous replication is as a result that the two strands in a DNA molecule runs antipararell, which means one strand run in the 5' to 3' direction, while the other is in the 3' to 5' direction.
The strand which is discontinuously synthesized is referred to as the lagging strand.
Discontinuously synthesized strand produce small DNA molecules attached to its own primer RNA called the okazaki fragments.
<span>Nudation is the process wherein an ecological system experiences new growth after a major event. Given that a drought killed all of the plants in the farmland and the wind and birds moved new plants into the now barren area, this is an ecological succession.</span>
