Answer 1

Sure:

static Expression<Func<TModel,TProperty>> CreateExpression<TModel,TProperty>(
    string propertyName)
{
    var param = Expression.Parameter(typeof(TModel), "x");
    return Expression.Lambda<Func<TModel, TProperty>>(
        Expression.PropertyOrField(param, propertyName), param);
}

then:

var lambda = CreateExpression<SomeModel, bool>("IsAlive");
