Which structures add to the fluidity of the plasma membrane:
Stels [109]

Answer:

(a) Carbohydrates are the structures  which add to the fluidity of the plasma membrane.

Explanation:

The principle components of plasma membrane are lipids, proteins and carbohydrates which are attached to some proteins and lipids. Membrane fluidity means how much viscous is the lipid bilayer of cell membrane? The membrane phospholipids absorbs fatty acids of different lengths and saturation. When there is amore distance between phospholipids fluidity increases.Another one is the  temperature and cholesterol. So these are the three factors which affects the fluidity of the membrane. The rate of saturated and unsaturated fatty acids decides the fluidity of the membrane at cold temperatures. Cholesterol take up the tasks as buffer blocking the lower temperatures from fluidity inhibition and blocking higher temperatures from increasing of fluidity.

A substance synthesized at the cell body must undergo ______ transport to reach the synaptic knobs.
cricket20 [7]

The cell body must undergo Anterograde transport to reach the synaptic knobs.

The synaptic feature is to transmit nerve impulses between two nerve cell neurons or among a neuron and muscle cellular. Synapses connect one neuron to every other and are thus liable for the transmission of messages from the nerves to the mind and vice versa.

Synapses are a part of the circuit that connects sensory organs, like those who come across aches or touch, within the peripheral frightened gadget to the mind. Synapses connect neurons inside the mind to neurons inside the rest of the frame and from those neurons to the muscle tissues.

Synaptic transmission is the method at synapses by way of which a chemical sign is launched from one neuron and diffuses to other neurons or goal cells where it generates a sign which excites, inhibits, or modulates mobile hobby.

Which of the following has a chance of being identified by genetic screening?
SOVA2 [1]

Answer:

A genetic screening test is more likely to detect genetic disorders.

Explanation:

A genetic screening is a tool used in the field of genetics to investigate the normal configuration and alterations in genes. It is based on the identification of an individual's DNA, proteins and chromosomes.

<em>One of the main functions of genetic screening is the </em><em>detection of genetic disorders</em><em> in an individual, before or after birth. </em>

Phenotypic expression or severity of disease are physical or functional expressions of genetic disorders, while treatment are the specific actions for these disorders.
