Binding of ________________ to receptors (ligand-gated) on the sarcolemma at the neuromuscular junction is vital for depolarizat

kifflom [539]

Answer:

Binding of ACh (acetylcholine) to receptors (ligand-gated) on the sarcolemma at the neuromuscular junction is vital for depolarization of the muscle fiber.

Explanation:

It allows acetylcholine to be released into this synapse when an action potential hits a neuromuscular junction. Acetylcholine attaches to the nicotinic receptors localized on the post-synaptic membrane of the muscle fibre's motor end plate, a specialized region.

Hence , the answer is ACh (acetylcholine) .

Leona [35]

Answer: High density lipoproteins (HDL)

High density lipoprotein can transport back cholesterol and sometimes called "good cholesterol". Patient with too low high-density lipoprotein will be considered having dyslipidemia(disturbance in cholesterol concentration) when other cholesterol considered as dyslipidemia if its too high.

In maize, liguleless (l) is recessive to having ligules (L), and dwarf (d) is recessive to tall (D). These two genes are linked

bearhunter [10]

Answer:

given,

LL║ll and DD║dd,

after crossing over, Ld║Ld × lD║lD

LLdd × llDD

in F1 generation, they will give, LLll, DDdd, LLDD, lldd → LlDd

in eF2 generation, the offsprings will be, LLll × DDdd

LLDD ,LLdd, LLDd, llDD, lldd, llDd, LlDD, Lldd, LlDd

1. yes, these genes are coupling.

2. → phenotypes of parental genes = ligules, liguleless, tall and dwarf

genotypes of parental genes= LLdd, llDD i.e; heterozygous

→ phenotypes of F1 generation = 25% Ligules, 25% tall, 25% ligules-tall, 25% liguleless-dwarf

genotypes of F1 generation = heterozygous ; LlDd that is ligules-tall

3. recombination frequency= no of recombinant / total progeny × 100%

= (1344+1344) / 6156+1344+1344+1156 × 100%

= 2688/ 10000 × 100%

= 26.88 %

that means linkage happened

and the map distance is 26.88 map unit.
