Answer:
The heritability of type 1 diabetes is likely high, indicating that genetics plays a larger role in the development of type 1 diabetes than the environment.
Explanation:
Identical twins are formed when a single zygote separates into two embryos after the process of fertilization. Hence, these twins arise from the same egg and sperm.
Fraternal twins arise when two different sperms fertilize two eggs at the same time.
Hence, we can say that the genotype of the identical twins is similar.
The results from concordance data prove that genetics play a higher role in type 1 diabetes.
Answer:
A. Calcium would be transported to the sarcoplasmic reticulum therefore contractions would cease.
Explanation:
A muscle fibre will stop contraction immediately ATP is used up. Also, muscle contraction will end as soon as the information from the motor neuron stops. This repolarizes the sarcolemma and T-tubules, thereby closing the voltage-gated calcium channels in the sarcoplasmic reticulum. Calcium ions are then pumped back into the sarcoplasmic reticulum, in order for tropomyosin to cover the binding sites on the actin strands again.

Answer:
The membrane will move to the left in view of the applied pressure.
Explanation:
The scenario described can be perfectly illustrated through understanding the concept of osmosis.
Osmosis can be defined as the movement of particules or molecules in a solvent from a region of lower concentration to a region of higher concentration, through a semi permeable membrane.
To put differently, the movement of water molecules is from a region of lower osmotic pressure to a higher one. And for osmosis to be achieved and water molecules evenly distributed, pressure built must be slow and steady to a state of high or equilibrium.
This often results to movement of membrane to the left as a response to the osmosis phenomenon. Increasing the number of water molecules in the extra cellular fluid will thus accelerate this process, increase the pressure built up, and thus generate ripples from a lower area to a higher one. Osmosis is thus gradual and steady.
Yeah!! As it acts in slightly acidic medium i.e., of pH 6.8 so, acidic conditions deactivate amylase enzyme...
