Where are the answer options and a picture of the problem?
Answer:
10 arrangements, although the parents have brown hair, they have a recessive allele for the blonde hair. The two brown heads can make a blonde or brown and or course even a red haired child. In this case the parents with dominant brown hair have a recessive blonde hair giving them a chance to have 10 arrangements to have blonde hair due to their recessive allele.
Explanation:
Heterozygous means that to have inherited different forms of a particular gene from each parent. In this case the children will inherit both brown and blonde hair genes.
Answer:
d. more permeable to sodium ions.
Explanation:
The binding of Acetylcholine with the receptors at motor end plate facilitate membrane permeability to sodium ions therefore opening of voltage gated channels for sodium ions.
Sodium ions diffused into the synapse of post synaptic neuron at the neuromuscular junction.
If the stimulus is up to threshold levels; more chemical(neurotransmitter) gated sodium channels opens, and sodium ions move into the synapse to depolarize the membrane with reversal of charges to generate action potential.
The continuous binding of Acetycholine , leads to permanent opening of sodium ions,and over excitation from depolarization. Acetycholinesterase enzymes breakdown Acetycholine to choline and Acetyl Co -A. These are recycle back to Acetycholiine
Answer:
One should use less energy and embrace alternative energy sources such as wind or solar energy. Will try to give what is taken away from the earth by giving back to it. Such as afforestation should be done
